A strong engine block is the foundation of every powerful and long lived turbocharged engine and today I'm going to show you in detail the process of building the engine block that I will be using in my turbocharged engine. Addtionally we'll be addiing up the costs of all the elements in the build to see exactly how much a strong, fully machined engine block with all new parts costs. Also links to all the parts you will see in this video are in the description.
The engine I'm building is a modest 1.6 liter Toyota 4AFE whose power output I'm planning to triple by turbocharging it. The planned application is street and track driving which means that this an enthusiast level build and has such a budget.
As I didn't want to remove the existing engine from my car in the interest of keeping it on the road for as much as possible I decided to buy a junkyard engine and build it. Obviously the first step towards building a block is to completely dissemble the engine and the engine block and remove all the internals from the engine block.
As you can see we are working with a pretty old school closed deck cast iron engine block. Although cast iron blocks are heavier than their aluminum counterparts they are a good choice for turbo builds due to their increased strength and rigidity which requires no or minimal reinforcement to cope with high amounts of boost.
Once the block is dissembled the next step I have taken is to do all the necessary machining. And this includes boring and honing the cylinders for 0.5mm oversize pistons and decking the block to achieve a perfectly flat surface for the head gasket.
Another type of machining that is often done is align honing which looks like this. This ensures that all the main bearing tunnels are of equal size and in perfect alignment with each other . Although many machine shops in my are offer this service I decided against doing it because all of my main bearing tunnels were within spec. align honing is good practice but it requires a lot of operator skill and all the tools to be equally worn. I have seen some negative experiences from align honing that unfortunately did more harm than good so after taking into account my current measurements and the difficulty of finding Toyota 4A blocks I decided to not take chances and leave things as they are.
I also machined the block to allow the fitment of oil squirters. This not something that is typically done and it did create some minor damage on the block which needed to be welded up but more on this later.
After all the machining is complete I decided to remove all the loose surface rust on the block to prepare it for painting later on. But what's much more important than rust on the outside is cleanliness on the inside. The block will be full of metal shavings and dust after machining as well as grime and other debris from previous engine operation. This is why cleaning the engine block as thoroughly as possible is incredibly important for any engine build. Any metal shavings or other foreign matter left inside the block can cause engine damage and ruin your investment. I cleaned the block by spraying gasoline under pressure into every nook and cranny. Gasoline is a good solvent and helps remove old oil gunk and grime and it also flushes out metal particles. It is especially important to clean every engine oil passageway. These can be found at the oil filter location, at all the main bearings, as well as inside the block going to the cylinder head.
Another extremely important area to clean is the main oil gallery. In my case it's even more important because I have drilled holes and cut threads into the main oil gallery resulting in a massive amount of metal shavings inside it.

Thanks, I'm interested to know what process you're using to determine what alternatives there are compared to stock parts from the Toyota Electronics Parts Catalog? For example how did you determine that this 4AGE crankshaft is compatible with the 4AFE engine. How do you find companies like MRPLTD, and what criteria do you use to determine if their parts are of reasonable quality?
Great video as always! I'm curious, did the shop rebalance the rotating assembly after notching the pistons for the oil squirters? While it's not a lot of material removed, I'd worry it's significant enough to require rebalancing.
Hello, what is the thread on those banjo bolts for the piston squirters please? I have modified a Ford Pinto block and fitted a set squirters to it, but I would prefer to use valved banjo's instead of the straight through ones.
@@kingcosworth2643 I wish you asked before, they're in now with loctite and I can't check any more. Sorry. But you can use the part number and order one from Toyota to test?
@@d4a That sounds good, have you the part number, or now where I could find it, thanks!
Awesome video! As an engineer, I highly appreciate all the specifications displayed on the screen as well as your reasoning for choosing particular products and solutions for your needs. Even though I don't understand half of it.
While I'm not an engineer, i found myself with far fewer questions at the end of this video than any other DIY guys out there. i don't think i yelled at the screen once hahaha exceptional content, definitely a new favorite Toober
Honestly, $2000 USD is cheap for a build with this much detail. Amazing work! I think 300HP will be no issue for this engine.
Let's hope so! Don't jinx me 😂
A stock block can handle 300hp
@@kensmechanicalaffair that’s what I thought
@@kensmechanicalaffair For how long though?
@@BigUriel Forever, lol.
Super exciting to see this engine build finally coming together! Can't wait for the first test drive video!! Awesome work, D4A! Love your content.
When we built the last complete engine I did, the biggest thing was having a plan in place & following it. The engine, a Buick 3.8L/Series II, is on Ward's list of best engines. Machining was fully done, used ARP attaching hardware kits (both stud & bolt). Factory rods are powder metal forged units, Mahle pistons with better ring sizes & longer skirts. Cometic headgaskets. Intercooler (water-to-air). Eliminated the CR balance shaft, Closes double roller chain & tensioner. Upgraded oil pump. It's been 8+ years and it has had exactly 0 hiccups.
Supercharged?
3.8 series 2 is on my list of worst engines
Yo, I’m looking at building a V6 ecotec for my Vs holden statesman, I’m looking at getting around 500-600hp capable of handling an aftermarket supercharger? Easy you reckon or what?
Awesome to see the build coming together! You must be getting excited seeing all these parts actually going into the block!
So good job full of details. I am so excited for this build. Can't wait to see it fires up. Go go go.
I was searching for a channel exactly like this for years, i found you trough instagram initially. Thank you for your always enjoyable and especially never boring explanations! Keep up the good work!
I cannot stress what a great and educational channel this is, thank you so much for your videos, this is genuinely verging on a free engineering course. ❤️ Love and respect from Malta.
I’m so excited for this build, this will be an inspiration for me for when I build my own.
This was tremendous. Best engine build video I've come across thus far. Your level of detail and explanations are unmatched in my experience.
Very excited to see it all come together! I can't wait to see the smile on your first track day😎
I usually paint the block any color but black so that any leaks are easier to identify. Great to see a vid of him actually doing something instead of a white board.
Looks great! Every boy's dream of building a powerful engine. Love your detail, as per usual. Gotta say though, I find you're very adventurous for adding on those oil squirters and notching your pistons for clearance! Not something I would have the guts to do but I'm very impressed by your intuition.
im so exited for you project mate! keep it going, i await for more detailed shoots!
Great vid and explain. Also it's very good that you show us the parts & costs. Thanks. Up to the next
hold on. you didnt mention about balancing the piston weights after you added the notch. i hope you did it without mentioning. this build reminds me about my very first engine build but i did N/A 4A-F. a mechanic helped me to torque down and assemble it back to the car. it was such a struggle to tune the engine since i use 4A-GE pistons but managed to make it runs smooth and torquey. what an experience for a mid-schooler me lol
He balanced the pistons when they arrived and its only a small notch. I'd say they'd still be within 1 gram of each other which for 6000rpm will be fine. If you're going 11,000 then maybe balance them better....
@@1one3_Racing i see. thanks!
Not recommended..
You are awesome. The content you are creating helps someone like me in understanding engines better. Thank You. Keep it up. Subscribed.
All your videos are highly informative and educational.
So like.. this channel gives me engineering explain vibes, but it a waaaaay more digestible format, you’ve earned yourself a sub!
So cool ! I can't wait to see more, your built is finally comming together ! :D Also, it's nice to see the cost because it's not over the moon and with some saving, might be possible to do one, one day :)
Great stuff! Looking forward to see what this beast can do. 👍
Badassery happening on this channel! Doing things legit is ALWAYS the way to go if you don't want to end up just another MEME. Keep up the awesome work!
13:10... this is what I did with my Chevy Ecotec build I have never had any issues after notching for my oil squirters 14:40... as long as your mains measure 0.0005 within tolerance you do not need to align hone...for main studs...
Awesome bro, love what you did with the 4afe block and the adding of the oil squirts, block came out boss man I use to have a strong 4afe normal aspirated In a Toyota conquest body many moons ago
My ONLY concern was when modifying the piston skirt to clear the oil squirters. .. there appeared to be some sharp edges. I hope you rounded those off to prevent stress risers. . .
Definitely did that, I just couldn't shoot everything. I was drowning in footage as it is 😂
@Mr T the owner wont like the stress if the bore scratched to hell
@Mr T the ones on my hand? just a cute night lamp
@Mr T HAHAHAHAH
@Mr T i dont mind being gae tbh. i like cute girls
“Getting the block clean will make you dirty” 😎, your videos just keep getting better, thanks.
Always great content. We appreciate you 🙏
That's very exciting and of course, informative!
Terrific and thoughtful presentation! Thank you!
I love the idea of this video, not only is it enjoyable to watch an engine being rebuilt and upgraded, but I like learning so much from clearly knowledgeable person and not a rambling idiot talking too quickly
Snap ring orientation explanation was cool , learned something today.
It's always best practice to align hone when changing to studs or adding something like main girdles. Hopefully you don't get any distortion in the block. Good luck with the rest of the build!
Thank you for the great content. It's educating and enlightening. Spasiba!!
Loved the video, great job, very detailed and informative. Thanks :)
Man im hyped up thx for making this video!
I can't explain to you how happy I am for your content, there are so many youtubers one here who act like immature clown fools when explaining cars, they goof around like we have time for all the bs entertainment and foul language, so many young hipster trendy foolish behavior, I don't have time for them, its a refreshing experience for your channel, Thank You
I like this built ❤ it's always nice to see someone using f-head for performance purposes 💪
I can’t wait to see it running !!
Awesome vid. Thanks also that you show us the costs. Love it
Exiting stuff, keep us posted!
Seeing a 4AFE (I drive a bone stock T19 Lean Burn Carina) and an Insize calliper (one of my most frequently used tools) made me feel wholesome :) Great project! Love the humble Toyota four bangers!
Excellent video Bro. Keep it up.
Dude, you got that Slav squat on point!
Man, how did I only just find this channel, this is great.
Very good. Ready for the BOOST!
Sometimes I'm thinking what these guys do for a living and how they have so much time to spend on such builds. Do they have a family, a mad girlfriend, like wtf? Super happy to see someone put the time and effort, great job!!!
Girlfriend? Your car is your girlfriend.
He does have a family. Just an incredibly hard worker!
Some guys decide to spend more time in the garage due to a girlfirend or wife.
Brilliant video...keep them coming 👏
This video was very informative
When it time for the first startup plenty of us would like to see it live!
Love it bro , awesome vid
This is gonna be a great build in the end
Great fun old Toyotas I love the way there's so many interchangeable parts with different engine's & cars throughout the range in the 80s-90s my old mr2 mk1 fitted with supercharged engine also fitted a bigger supercharger from a different model can't remember which then found that gt4 st165 brakes fitted was a track weapon
Thanks for this incredibly useful video!
Man this is a really well made video.
For increased reliability use full groove main bearings, this guarantees 360 degrees of oil supply to the big end bearings and reduces pulsation in the oil supply to the bearings.
Amazing video, very educational 👌🏿👌🏿👌🏿
Good Job there is many thing to think of when use a block not ment for the power you make. Look forward to see it finish and tuned on Dyno. Thanks for uplode.
This made my day
Its also a good idea to start with a block that has enough rigidity designed in. A block that was never designed with higher horsepower/kw output in mind is not going to take well to forced induction. One good reason for align honing the main bearing bores is to ensure that they have a common centerline. Your bearing bores may be in spec size wise but there is also a tolerance for alignment.
Beautiful, Beautiful!
Did you balance the rotating assembly? Especially the pistons after notching them for oil squirter clearance?
please answer this cause it really bothers me :)
Piston balancing is very important..to gring it like this make the engine vibrate on high rpm.
fr idk why he didnt just rotate the oil squirters.
if you reduce just a small amount from the skirts it will not impact weight much. In this case he will do all 4 equally. I hope he answers your question. What I wonder is if he dynamically balanced the rotating assembly.
@@wafiydeejah Especially a 4 cylinder.
I love this channel. Thank you :P
You make this look so easy to do lol Making me wanna upgrade / build my 1.4L engine
Awesome video, thank you 👍
This was fantastic! I find myself wishing there was more! Exceptional content, and your accent is also quite entertaining, my wife loves it haha please continue to fulfill the what, where, why, & how as you did in this DIY. the "when" doesn't seem so necessary. seriously though I have to give credit where credit is due... im not sure if you recited any of this but the execution is superb. Articulated in a very easy to comprehend approach and enough details to answer many questions i have in my head while watching but not too much where it takes away from the point. very educational for the Noobsies and professionally delivered in a manner i didn't mind following along when it was a subject ive probably heard a million times now hahaha very well done sir! you have an appreciative fan here looking forward to the next!
I wish I had you knowledge I’d be working on engines right now :)
Wow thanks for al the use full information! Im building a 7age engine(also turbo charging it) and happen to have almost the same setup you are using! 4agze pistons with max speeding rods 😂💪🏻. I assume i can use most of the modifications you use and i think im gonna use your video as a base line for my build! Just waiting for a crank sprocket to correct the timing for the conversion and then i can start building 💪🏻
Nice stuff I would love to hear numbers and calculations about expected torque the components resistance... ECT
Cylinder heads usually require the most attention. Can also be very complicated as well unless you stay with standard.
Great vid, thank you.
Very nicely detailed step by step on building the engine block. What process was used for the block weld repair, and why was it necessary?
Interesting! And nice project ! :)
This is awesome, I did the same as you with a 3SFE, with maxpeeding rods, 3sgte pistons and crankshaft with arp, my isn’t done yet, i need to machine the head because a high compression, the 3SFE look too similar to the 4afe.
for me. it was extremely well balanced, no stroker, stock rods and pistons{.080 over} and headwork done by a specialist. then not touching anything without asking the tuner first. reliable as hell.
One of best engines ever made.. Bever stop..
boost is pricey! but info given here is priceless!
A real world self build engine, all be it, by someone with good knowledge. Good price for bore, hone and decking, I charge €500 for a four cylinder 🙂👌
Thanks for all your tutorials. Did you chemically clean the coolant passages in the block? Scale is an effective insulator. More important for the head but significant for the block none the less. Hydrochloric acid works a treat in cast iron blocks.
Superb video.
This is going to be fun to watch :-)
How much does a shop charge to hone out small bore of the rod
Legend says he is still cleaning that engine block to this very day
Some great info here
Me and you are aligned. But I'm actually doing the turbo on the 4AGE. I'm using the MRP turbo kit from New Zealand, and a Borg Warner 6258 efr. Thank you for showing the oil squirters machined in, I really didn't know how I would get those in. I was considering just using e85 to cool the Pistons but now I might be able to get away with just using oil squirters
why not Garrett turbo? i heard Borg Wargner turbos are not good quality
Some 4AGE blocks come with oil squirters from the factory…especially the later model ones (some 7 rib, not all).
Worth a mention here, the thickness of the wrist pin is critical to a good build. I run .200 wall pins and even .250 wall pins on 1000+ hp 2jz engines. Its a lot of added weight but the piston isn't strong enough to support itself and a flexing pin.
nice build
I am looking to build my 96 4AFE Corolla with a SC 12 supercharger using as many stock parts as I possibly can. I do have a SC 12 intake manifold as a template because the fourAFE is drastically different. So that will need to be custom-made. And I’m doing this just to see how we can handle boost. My second plan is to Frankenstein a manual 2AR Out of a sion TC into my 96 rolla lol
Thanks 🙏🏽
You could put some custom spacers between block and nozzles to get more clearance from piston
But then they would hit the crankshaft
What he says about the gudgeon pin snap rings when it comes to installation orientation is one of thos things you really do need to check/do. A friends Yamaha Raptor seized and upon pulling it down what had happened is that both those snap rings would of been installed sideways (one still was) and one had snapped in half causing the gudgeon pin to slide to one side and out of the boss in the piston. The remaining boss couldn't cope and broke so the pin got pulled out of the bottom of the piston and as one would imagine. If you install those pins sideways and run the motor at high revs, the snap rings will eventually fatigue and snap.
Man my 93 Corolla sure would like to triple the power output of its 4AFE
Great info...thank u
You should do a iconic engine video on the Ford barra straight 6.
great commentary.
Thank you for the awesome info...I'm trying to come up with one engine from a Toyota 4E & 5E engines...what are my odds
Awesome video as usual! Quick question. Isn’t it necessary to line hone when using ARP studs on the main caps? In my case (VW 1.8t 20v) I decided against ARP because the increasing load you are supposed to use on the bolts meant a line hone was necessary and hated the idea the same as you.
Shipped a full 5.0L crate motor from east coast to FRA by air for $650. But that was two years ago. Not surprised if that price has doubled by now.
Bravo!!!
Any tips for me in, for future me may attempt, building a high RPM NA W8 engine, using custom valve technology like on the Koenigsegg Gemera
