Here is a good read on high egt's and what people have done to try to fix the problem http://forums.nasioc.com/forums/show...ht=channel+egt.

Thanks, I will look into them. I may even get with a machinist about possibly designing a block guard (deck saver) for the WRX also if opne isn't available yet. Thanks for all the help guys!! i just need to figure out what cranks are forged and whiat ones aren't in the suby motors and I'll be set

PS- oh yeah, what about heads- are the stock ones workable or are they boat anchors? If not, what should I look for? Damn, I have been too spoiled by the DSM's lol..

Sorry about that, I forgot to post the link (bangs head on desk), I edited the post and included the link this time.

I cant help you with the question about the heads since I have no experience modding above 285 hp but Ron at axis knows a lot about makeing big power and he would be a great person to talk to.

Here is a shop that sells used JDM sti motors and trannies http://www.finelineimports.net/subaru_usedengines.htm.

Not too concerned about the AVCS- won't make any more power, just help give more bottom end, not too much of a concern. I am more worried about flow of the heads. Are there any that actually flow better than others? Thanks again.

Tranny problems can be solved with an 5sp STi RA gearset and stock 5th gear and new syncros(usdm). That is what i am going with when my tranny blows. I would stay away from NOS on the stock motor. Also as said before, if you use the FP green on the 2.0 you will need engine work. You would get more power out of a VF34 and accessories with no block work and it would be reliable. If you rally want big power go to Esx. They use axis engines. link:http://www.easystreetmotorsports.com/

I am probably just going to look for a 2.2 closed deck block and build it from there and set mine on a stand in case I ever need/want it later on. I would prefer to have a brand new ~1200 mile motor as a spare(mine) then rip it all apart and build it anyway. The VF34 will never meet my goals, so that turbo is well out of the equation

. I will look into ESX to see what they have, however, no one builds my engines but myself and my machinist

, so I do not know what I can get from them besides parts? Thanks again guys.
