m20 turbo stroker love???

Its a really expensive adventure, considering you can get a full i motor for like 500 bucks...

Somewhere on here I found a thread where the guy used his e head on his e bottom end but ported the head to i specs. He used the i intake and other components but the motor internally was a e. From what he was saying the compression didn't drop because all the e stuff was used. Does this sound like a good idea ?

Yea, it just lowers your compression alot and aparently completely ruins the squinsh area of the combustion chamber. The Super eta pistons are alot better since they are designed for the i head.

you are going to need super eta pistons. It's been awhile since i've read the stroker threads on e30tech.com but they cover this topic thoroughly so i would do some reading there.

A lot of people run i heads on normal eta pistons...

[backtrail69]

You REALLY need forged pistons for HIGH boost and reliability.

Are these motors running stock eta pistons ?

-Chris

Yes. They don't tend to last long.

There are at least 2-3 guys on e30tech running that same setup. Stock eta bottom end and i head pushing 18+ psi. BMWSOB ran an 11.6 with a TCD log manifold.

ouch

I wouldn;t slap THAT eta bottom end on just yet.

if I am not mistaken, I believe you need you swap the pistons (since it;s not a super eta)



anyone have more knowlegde about simply slapping a non-super eta bottom end with an I head?

[jay dot dog]

ok, i want to build a m20 turbo stroker, i have a 1985 e motor and i can go and get a i head off of a 89'ish 525 if i do i'll slap the head on my e block "with all new seals and gasket's from what i have heard it sould have about 8-4-1 compression ratio very good for boost i just wanted to know how much power i could get out of the motor with this setup,, 255 walbro 24# injectors or maybe 32#,fmu,61 trim turbo 3 inch in 3 inch out running about 10 to 13psi,big boy front mount intercooler ,2.5" hard pipeing,hks ss bov,msd boost retard,m30 afm.. i want to go MegaSquirt but i need alot more info on what i need to buy to get it working correctly.
