Default Cam, head, hybrid questions...

I am planning to go the ej257 route like many others. In looking at the heads and com options I am not sure which way to go. I am NOT building a drag car, or a dyno queen. I want a strong consistent power curve.

I also want it to be cost effective.

I am thinking something like the following:
ej257
ej205 heads
ej257 cams
fp16g evo, fp20G, or other turbo (still researching, much to learn here)
800cc injectors
TMIC
255lph fuel pump
TBE (already on car)


Questions:

Will the ej205 heads and USDM Sti cams work well together? What kind of power are people making with this set up?

What other head/cam options are there that will NOT cost me an arm and a leg?

Does anyone have dyno plots showing STI cam vs WRX cams on a 257 hybrid?

I don't see porting and expensive cams as a viable option for ej205 heads when I can buy V8 head/cams for 2K. I want to cut money out where it makes sense to do so, and not at the cost of quality/reliability... remember I am not out for big peak power numbers...



Thanks in advance

Chris

Check with SBW. He is using an Axis 2.2 with WRX heads and USDM STi cams. I know it is not exactly what you are looking for but it may give you an idea. He has a thread from a pump gas tune in PPB

i will be running that EXACT setup in less than a week. i spoke to franz over at ktr who will be tuning it and he said he's expecting around 270-280whp on 93.

270-280 seems low depending on the dyno. What does a stock WRX or STi make on that dyno.

The 2.2L is a nice motor, a lil' extra down low with the rev happy top end of the JDM motors.

ahhh, that's a little more inline with what I am seeing.

I like the STi block for it's low cost and the fact that it is OEM, and non-forged. IMO forged are great for race cars but not so much for a everyday car. Hyper pistons hold tighter manf. tolerances and as such should last longer under less than race conditions.

My biggest concern at this point is what to do about heads/cams. I keep finding the costs for ej205 heads/cams/P&P are within ej2087 V8 heads which are a much better base AFAIK.

I would like to see a nice chart showing flow rates, with various heads/cams.
