I have decided that i will be better off building a car that was meant to be rwd for drifting rather than what I have been doing so my parts are going. I have for sale Tein Flex's for gc8/early leg etc - 1200 jdm early wrx heads - 300 sti pinks - 300 ej22t block decent shape - 600 ej22t heads decent...

:lol: Yes, I realize I'd need to put the stubs in the hubs for the wheel bearing to ride on and to keep the wheels on. :wink: http://www.clubwrx.net/forums/showthread.php?t=27532&page=5 Scrolling down to the picture on this page, my diff is on the left. What is there to weld together? I may ver...

Breaks axles every time? that must suck, I have yet to break an axle and I have been running rwd w a "spooled" rear diff ( welded, more consistant for drifting ) for a year now and have yet to break anything. If I were breaking them that much I would either convert to sti rear diff/axles e...

Sounds good to me.

those heads should be a 49cc chamber, I dont have time to do the math at this second but it would be in the mid 7's

no problem.

( fractured back?!! OUCH )

well it really depends on where you had it tapped, but yes its a possibility. Put some zip ties on the "T" to keep the lines from comming loose.

did you check for boost leaks? look for a spot where your pressurized piping oculd have came off ( like at your IC ) if thats not the case I would look at your turbo. if all of a sudden you are not making boost, you either have a boost leak somewhere or your turbo went bad ( which probably isnt the ...

yes you should be able to without issue.

I agree, but as I will be in area's where off boost is of issue, and I want to have something with off boost grunt a little ( and it is my daily driver when the weather is not good enough to be on the bike ). I am concerned with moving the thing from a stop. Again , its just my preferance. Now I hav...

I am not saying it wont function, I personally think that c:r in the low 7's is too little ( for what I would do in my personal setup ) , unless you are building something that you are going to boost a ton, but off boost performance will suffer a bit.

problem is without actually cc THOSE heads, you dont really know what they are ( from my experiance so far , looking at the available charts havent been so accurate ) . I would be interested to see exactly what you have, and see what your car is really running for a compression ratio.

did you cc the heads ever? were they shim/bucket lifters or hydro w rockers?

bah,,

just go standalone and call it good.


I wish hydra would make a damn wire in.....


oh well, looks like I will haltech it.

yes, the observed engines I had were all turbo ( only ones I ever bothered to hook a pres. guage too )

these pressures are close to most i have seen as well. subaru's run a lot of pressure once off of idle.

there is that ejspecs page, although I dont know how much to trust it,
I saw 28cc for the pistons and 40cc for the chamber.

I think the head gasket compressed is ~1.5 mm for the 2.2 gasket

I have sohc 22T heads on my shelf at home, if I get a chance tonite I will cc them.

best bet would be to CC the heads and find an accurate chamber size, seems there were quite a few. Once you have that you can do the calcs to figure out what it is you need to do . But yes, most likely you would end up with a very low comp ratio, while it would work, it would definitly be sub-optimal.

but do you know what heads you have? if you have a small combustion chamber head it will be much better than if you had the ones I had. I seriously doubt you have 57cc chambers.

also,

what gasket did you use?

would depend on the chamber volume, it could work if they are the smaller norm ( around 49cc ) and I still think that your comp ratio with stock gaskets will be too low. If you ran the thin gaskets it makes it better, but there isnt a good thin option for the 2.2 either.

Tien Flex's adapted from a GC8 , I love them, as low as I want it , with camber adj, and damping adjustment as well.
downside is the price, luckily I was able to get them at wholesale but stull not cheap.

Yea, I figure that my 1 cc vairiance could have been from a little carbon on the valves etc. considering I got that close consistantly I say 57's it is.

ack! that would suck NA , I assume that was a "need to get a motor running out of this pile of spare parts " project?

ok. sti block arias forged pistons @ 22 cc volume sti stock gasket @ .21 compressed deck clearance of -.254mm 20g heads @ 57cc volume std stroke/bore for 2.5 nets : compression ratio of 8.06/1 <- acceptable however if I chose to run the ej22t block unmodified I would end up with somewhere around 7.2...
