what intercooler you using? Might be some gains there... headers p&p'd? You could always go with a hybrid block too...

Theres always the water/meth injection, not a permenant power adder though. Are you running a 91 or 93 octane map? Can be some small gains tere sometimes.

I would go for the cams with a good pnp for your heads and new springs/retainers.

It will move your power to the right, but with the new springs/retainers/cams you should be able to rev a little higher to use more of the top end power.

yea all this is gonna cost me some $ lol.....well right now im at 19-21lbs of boost and no i did not get it dynotuned..so i don't know exactly how much whp i got, im guessing around 305.....give or take....but would the stock block be able to handle reving higher? i just dumped a crap load of money about a month ago and i could throw away $350 for my buddys cams its just all that good stuff that comes along that cost money, but if i do buy the cams i would work on it at toward the end of summer......anything else i can do to squeese more power?

Cruising at 65 with the CC on a flat road, I could get about 30mpg out of the WRX, The STi gets 28 in the same condition. Around town I usually got 19 out of the WRX, the STi gets about the same. I accelerate more than I should...

SO I guess it matters how much freeway driving you do. If you stay in 5th for long stretches, the 2.5L WILL cost you some gas mileage but if you don't, it prob doesn't change much of anything.

Sorry to bring this thread back from the dead. I dont believe anyone ever answered his question about the block being able to handle reving higher. I am looking at cams right now, and I have the same question he did. The cams i'm looking at would allow the car to rev to 7500 (I would also buy valve springs). Would the stock block be able to handle this?
I am looking to get a little extra power without upgrading my turbo. I just put a 16g in last summer and i dont want to upgrade the turbo again so soon.
Thanks for any advice

I think the stock block would handle 7500 rpms.I would upgrade the head studs and head gaskets.

I agree if we're talking about the EJ205 (which we are) but I'll point out that the EJ255 and even the EJ257 don't handle RPMS past 7k very well. The 2.0L actually has some more room to play with. I'd do what dumdum said here before raising redline though. I just wanted to point out he's talking about EJ205s and not the 2.5L versions.

Ok thanks for the help! The cams I was looking at are stage 2, they are 264s. Do you think I sould upgrade my valve springs and retainers? Also someone mentioned earlier in the thread that you should port and polish your heads when doing cams. Is this required or just a suggestion?

Wouldn't he see some significant gains from doing headers? both in hp and torque I would imagine that would help his low end and his top end a good bit especially for the torque aspect if hes running a 2.0 liter? I think mosc might have mentioned the headers previously but I figured I'd bring that up because headers was something I was considering doing myself if after a while (hopefully a real long while after the 16g is installed) i get bored with my current set up or soon to be current set up.

Also I would think if you did like a intake headers n gears the car would feel much better and prob be a good bit faster...I know people usually say avoid doing the intake but I have heard that a intake goes great with the header back exhaust makes for a nice combination.

I don't know what you're talking about. The stock headers are pretty good.

Equal length headers will provide a nice power gain even over stock P&Ped headers.The stock un equal design is inefficient.NASIOC has a lot of factual data on this as well.
