Quality work. Probably worth pointing out the rings were gapped / ground prior to piston assembly to the right tolerance. Getting the rings right is super important on these engines along with using updated head-gaskets.
@@PMAutoworkswould love to know your gap and clearances for comparison with other people’s builds and why you chose them. More in depth would be great video.
I’ve watched this video about 10x most satisfying things in the world!!! I’m in the process of building my own block I sent it out to get closed decked!!!
I’ve got a type ra block with a bad rod bearing in my garage, I’m trying to get motivation to build it, and now I’ve got the bug, 5 videos in and I’ve got a parts list. Just need to find a video that details the exact sizes of ring gap, and other clearances that is ideal for 450whp with a stock type ra block. Might even try stock rods and pistons. Just replace bearings and rings. Good rods and pistons are so damn expensive.
can you post a video on how to install the shortblock into the long block please, that’ll be super helpful since that’s what i’m currently trying to do
are the rod bearings for those manly H-beams one-size fits all for a new nitride crank? tryna figure out if plastigauge and buying size A, B, C, D bearings are needed(kinda like hondas). Thanks man, great video!
Great video, but 500hp and not close decking a EJ257 is pushing it. Rated at 400hp max for semi closed here in the uk. Why not close deck it? Anyway great build 👌
500hp and no close deck is 100% pushing it. If it was a build for a client we would closed the deck but since it was our own shop car we decided to test the limits of the block. As of today, the car has seen multiple track days and is still running! Thanks for watching. 🙂
Great video, but aren't you ment to check the size of the oil control ring in the bore and trim ring gap if required, before putting onto the piston? Or was this done before video. 👌👍
the engine block you are assembling is forged ??? ... the block is new or can the old one be used ... ?? how much is the price ... I have made modifications and I have put a lot of after market things on my car and I have modified it in force and thrust and thrust 385hp has but after that I am using a lot of oil .. they say I need a forged block...
The EJ255 / EJ257 are essentially the exact same block (apart from casting the EJ257 designation in etc.) along with the factory crank and rods, The difference on the STi (EJ257) is the piston dish and the heads. So the EJ255 heads can be fitted to an EJ257 and vice versa but you must use the right headgaskets. Factory pistons are hypereutectic ones on both from factory, but it looks as if he's using aftermarket forged ones here. With 500HP being the aim for this short-block it would be pretty much certain as the stock internals would suffer over 420HP or so, and ring-land failures a real probability. (Which can still happen with a bad tune / rings on forged pistons too btw, but not as easily). The cylinders are likely overbored to standard. Standard is - EJ257 = 99.5mm Bore x 79mm Stroke.
Im killing myself over this build im doing watching this video was like being tapped on the shoulder by the subi angels saying "be one with the Ej my son"
Lol! Glad you noticed. We searched long and hard for the perfect set of pliers to build these engines. DM us on @pmautoworks instagram and we'll try and check for you at work.
Is that a new block you're installing on? I have ringland failure and am wondering if I can save money rebuilding rather than buying a new stage 1 shortblock.
It was an old block that we got machined and rebuilt. You can save money by rebuilding yourself but if you don't have the tools i'd recommend just buying a built block.
@@PMAutoworks So the cost of tools necessary for the rebuild outweigh the difference in price between a built short block and a rebuild kit with a machined block?
@@mikealmiracle4834 yes, some of the tools needed are torque wrenches, micrometers, feeler gauges, bore gauges, ring compressor, rod bolt stretch gauge.. it adds up quick
@@mareksumguy1887 May not hurt anything, but yes, clean oil should be used on the cylinder walls and piston skirts, and nothing on the rings, as the aim is to get the cylinder broken in / the rings to bed in and locate in the cylinder.
blobeye_dylann A properly preloaded bolt won't stretch with the cyclic loads. It needs to be adequately tightened to a load greater than the demand of the engine, and measuring bolt stretch is the most accurate way to make sure it's reached.
Although it wouldn't have been a bad idea, for our horse power goals we didn't need to close the deck. As of today the engine is still running strong after seeing countless track days.
Dude built this on a coffee table and that gives me hope that I can do this lol
You can do anything if you put your mind into it lol
I assemble on two plastic foldable tables from home depot, you got this.
Done that before!
assembling is way different than building, but it still requires skills though and he is skillful
Quality work. Probably worth pointing out the rings were gapped / ground prior to piston assembly to the right tolerance. Getting the rings right is super important on these engines along with using updated head-gaskets.
Yeah I did mention all the clearances have been done prior to assembly although I should be more specific. Thanks!

I'm buying an ej257 short block tomorrow.. thanks for the inspiration, pal!
Hell yes!
So satisfying to watch! Hopefully we see some Fa20dit builds .
Never seen someone assemble a block on a coffee table before lol
Lol yeah this was before we had better lighting in the shop. Check out our FA20 build video on our channel!
for 500hp i would have used ARP case bolts ! a real safe way to go .

Great video. How is it holding up to 500hp?
Wait.. you're telling me a days work can be done in 14 minutes and 23 seconds??!
Yessir!
One question: what was the reason for measuring the bolt on the rods when torqued to the crank?
We are checking the rod bolt stretch.
are the rod bearings for those manly H-beams one-size fits all for a new nitride crank? tryna figure out if plastigauge and buying size A, B, C, D bearings are needed(kinda like hondas).
Thanks man, great video!
No these rod bearings come in standard size and typically have perfect clearance. They also come in over and under size if proper clearance is needed

Hi Christopher. All measurements were done prior to assembly.
Bruh that looks easy...am going to open up my spare case halfs and get it closed deck so might as well learn.
Hey! What price should we expect for labor for this type of work? Thinking of having my block built as well, probably closed deck too
Labor rates depend on location. If you're local in California give us a call!
Came for the build but inspired by the track. What is the name of that beat please

It’s a used block that has been machined. Prices vary
When you’re torquing those connecting rod
Bolts what were you measuring using that odd looking dial indicator setup ?
It is a bolt stretch gauge. Used to measure the bolt stretch.
@Bryan Gombert measuring stretch gives you optimal clamping force
What is blue printing and balancing?
was thinking of purchasing a crawford built short stock- what else would i need besides the installation kit and new clutch?
We recommend getting ARP headstuds

What’s the red stuff your putting on the rod bearings? Grease?
It's called Redline assembly lube
... and he used about 3 times too much.... and you’re certainly not meant to use it on the piston/bores!
@@mareksumguy1887 May not hurt anything, but yes, clean oil should be used on the cylinder walls and piston skirts, and nothing on the rings, as the aim is to get the cylinder broken in / the rings to bed in and locate in the cylinder.
Hi Marek. It's moly based lube that cannot be used on piston rings and bores. This redline grease is fine to use on cylinder walls.
What's the gauge for when torquing the rod bolts?
It's called a bolt stretch guage
@@PMAutoworks What makes the bolt stretch important?

Is there a certain limit with these, with such high cylinder pressure?
Yes the stock block can only take so much.
