Impreza GC8 legacy 2.2t internals...

Im in the process of building a 98rs, I plan to utilize my DOHC heads on the 2.2 closed deck legacy block. My question is how reliable are the stock internals such as rods or valves and valve springs, could I run 20psi daily on stock internals with exception of some low compresion pistons?

If you use the dohc heads on the 2.2 your compression ratio will already drop to like 7.5:1 depending on what head gasket yu use.

I would get STi heads at least or the JDM ver.8 heads and you would have a crazy setup on your hands. But yes, 20psi will be no problem for that block for everyday driving.

Don't different heads have different sensors? Kinda like the wrx having less timing marks on the cam gear than a legacy?

I'm not sure if the 2.5RS SOHC motor had different dish in the pistons and different cc in the heads or not, if it's 49-50 like the DOHC heads on the 2.0 and EJ25's nowadays, then yeah, it would drop it immensely. with 20psi, I don't have any rough figure that would work dude for estimated power.

20psi at 9:1 is alot different than 20psi at 7.5:1 and of course 30psi at 7:1 is just kick ass.

EJ motor compression calculations this guy did some great calculations on a number of combos just scroll down the page a bit to see the results. BTW I have the 2.2 block on 2.5 heads using a cometic head gasket. I think I'm in the 7.8-8 to 1 ratio.

I have a justy. It is a 1000 horsepower monster. If you look in any 1990 + Websters Dictionary for the word MONSTER, you will see a pic of my 89 Justy 1.2 Liter NA. BTW I hate Mexicans, they are subhuman rabble! Did you they are so underdeveloped as a race that they can only see in grainy black and white images?

EDIT: I HAVE DYNO CHARTS AND IF ANYBODY WANTS TO GO FOR PINKS ( NON-MEX) BRING IT

Ok i see all this great talk about the 2.2T. Where is all the negative stuff about? They kinda change the block design for a reason but why. The 2.2T is a center thrust cranks while i believe after 97 they went rear thrust on all blocks after that. And if anyone else can think of more stuff do share. \

P.S.

i will be assembling a 93 2.2T w/ CP pistons, maybe rods, wrx heads and just want to be more knowledgable if things ever start to go wrong.

Site should be up. If you can't get it to work, try this
https://www.mail.experiencetherave.c.../images/ej22t/

Only real neg. thing I know about the ej22t is the heads. They have small valves, and don't necessarily flow as well as the ej20 or ej25 heads.

They changed the blocks because they cost too much to make. As well as they stopped making the turbo blocks when they stopped making the turbo legacies! Damn those fools!

The stock turbo pistons are still pretty damn nice. I just pulled (two hours or so ago) 4 of em out of my future new motor. They have at least 150,000 miles on them, maybe more. THEY ARE CLEAN! Ok, actually they were kinda oily, dirty and covered in carbon. But.... it was just oil and carbon. They look basically new under the carbon coating. I am currently steam cleaning them in the dishwasher. I will give them a double cycle to make sure my wife doesnt detect an oily taste on the silverware.

Yup, site will be up pretty much indefinitely. When I get done, I'll make a full write-up and move everything over to my main site. Similar to my AWD & 5MT swap. I'll have a redirect, so it should be a seamless transition.
