anybody know Blackbart?
Does any body know blackbart? he says he's got 6 2.2Ltr turbo pistons
con rods and things like that. would it be a bad idea to use "used pistons" in the EG33? at 175 for 6 it's kind of tempting.

I've never met him, but I know the Gen 1 Legacy folks rely on him for parts. I've never heard of any bad transactions.

might want to do research...I dont think the 2.2 rods are interchangable? Or was it pistons? I cant rememememember (Concussions are easy to get)

rods are good, pistons are a no go

I thought the 2.2 pistons were the same size. or is that for the 22b? i did a search
http://www.importperformanceparts.ne...ns-subaru.html says the EJ22t turbo pistons are 96.9 like the SVX's but if you guys have fist hand experience, then i'll take your word for it. i know you guys that have been turboing the EG are very sharp and know first hand a bunch of stuff. has anybody tried to put these in?

Theres more to pistons that width... The SVX pistons make a 10:1 compression on a non interference motor while the 2.2 makes 9.5:1 on an interference motor. The SVX pistons have more height and valve reliefs than the 2.2 pistons

uh tom, pre 97 the ej22 was non-interference, the ej22t was no exception, i'm not trying to belittle you. your probably right about them being different, just adding to the knowledge pot. no subaru motor with a timing belt was interference from the factory till 97.

so if it's a pre-97 the pistons will work? i sure didn't know about the valve reliefs! thanks for all the info guys. i havn't touched the eg motor ever. and i havn't been thinking about this project for about 5 years.

we had done the math years ago and found the compression ratio of the 2.2l pistons were significantly lower than acceptable levels. For ex. a turbo piston would drop it to 7.5:1 and an N/A piston was 8.0:1

Excellent, so i 'm not the only one that's wanted to put the 2.2 pistons in. but doesn't the 8.0:1 ratio mean we can put huge ammounts of boost? like 30 psi?. i better start saving then. BTW does anybody know the VE of our motors? (volumetric efficiency)

top VE our motors see stock is 98% as far as I know

Holy crap! that's awesome, do you know what it drops to when we put the 8.5:1 pistons in it?

not sure. The motors I have built were both supercharged.
