Smile another ej205 2.2 stroker thread

Hey guys! this is my first time posting a thread in the built motor section...here we go.

I am collaborating with another member on the forum to build a semi-closed ej205, and run usdm sti crank, rods, and forged aftermarket pistons. I am planning on running 91 oct. pump gas, and i want it to look stock under the hood so ill be running a stock location turbo. Currently my choices are tdo6 8cm 20g, HTA green, or an atp 3076 turbo, and im open to other options, just havent researched others yet.

heads that are within an ok price-

USDM sti heads- thinking ill get these ported and use them with avcs, im not sure what ill need as far as wiring, IA perf. avcs wiring kit?
pnp wrx heads with aftermarket cams
ver7 heads, dont know much about them though, early models were not big port
???



My problem is that i need help with choosing heads, and im debating whether i should go avcs heads or not, because if its not worth it i dont want to spend the money. Considering that we are doing all the labor, i dont think the longblock will run me more than 12-1600$ but i am willing to pay extra for avcs if its worth it.

My goal is to have a reliable (as in 50,000 or more miles) daily driver that will see 3 to 8 trackdays, a few autox, and cross country road trips every year. If my driving trends continue to go this way, i am looking at about 20-30k miles a year (2002 bugeye wrx with 153k on the clock)

I will be happy with a useable powerband, and as long as bottom end power is greater than what it is now with my stock td04 im happy. I hate numbers but 340-385whp range is the goal. Car will not be beat on or launched, but definitely driven hard on track days.

Any thoughts, suggestions, and criticism for this engine newb is appreciated.

the only semi closed 205 are the ones that you make yourself.
207 are semi closed deck.

your 02 ecu will not support avcs. that is unless you get jdm ecu,
but then to make it all work with minimum hassle you would need
engine harness & bulkhead ti ecu harness.

tuned a usdm legacy gt with vf-37 factory twin scroll that made
~330 whp @ 18~20 psi. but you said useable power band.

the amount of money you're about to spend it would be easier
to get a ej255/57 bolt on your wrx heads with the turbo of your
choice & call it a day.

we will pin the block and make it semi-closed, and i am probably going to go with the jdm ecu, tune it, and reflash the usdm ecu with that tune for obdII purposes. im also looking into a 257 bottom end, with ver.7 internals/ ver.8 heads, aftermarket forged pistons.

jax i see you post in here alot, i appreciate the feedback man.

I pinned my older phase 1 2.5 block with good results. The first time I ran it I didnt even have it honed, much less rebored to oversize pistons. So I know it works.

thats reassuring. My friend will be doing all the pinning and he has experience with it. Is it possible to run a 2.5 bottom end with ej207 internals and heads? im thinking i want the extra usdm displacement, and the jdm motor capabilities. I havent heard of it done before, probably because my search skills are crap

A 2.5 bottom end with 2.0 internals? No, you can't run 2.0 pistons in the 2.5.

Look a few threads down.... I am currently starting a similar build but with higher power goal I think. I am coming from the 2.5 hybrid route and I hated it. Such a rough motor.... I have been in ej207 cars and they are much smoother and just seem to be happier motors. The 2.5 hybrid is a knock happy setup. You are on the right track I would do the build you are thinking about and not go the 2.5 route!

oh i know, i mentioned it in my post, id be running aftermarket forged pistons, and get them honed and everything. im just trying to see if id be able to rev to 8000 like the jdm sti, and still have the bottom end torque of the usdm sti.
