Its time... 2.0/2.1/2.3 or 2.4 build ?
Fuel doesnt kill the motors unless its straight methanol which is corrosive. The E85 wasnt to blame its just a case of fatigue of the stock bottom end possibly. If the phone didnt ring off the hook I would have gotten to take a look at it today 
but thats all part of how it goes I guess.
Since we havent even pulled the valvecover off yet, most of the failure theories are just that. There are no leaks, holes, or otherwise, just no fuego underhood. I am going to go in early and make it my goal to see whats going on.
Just to cast my vote and my future build... 2.1 and 10:1

With a 10.1 ratio how much boost could be ran safely on pump gas on a gt35r? Also if you can't run more that 20 plus psi would it even make sense to run a turbo bigger than say a gt3076 since the turbo will never be in its "sweet spot"? Anyone on here do a high compression build?
Most of the high compression builds are either racegas only, pump meth, or E85ish...so I am not sure. 10:1 2.1's arent new though, they have been done in the DSM world for along time.
Main reason I am going to do one is the cost of the block in case of failure. The other problems that they have had in the past I dont think are totally 100% build related, more the crank oiling vs. rpm issues.

With that said - when tune up is correct - 20 PSI and pump gas is about the limit IMO on a 10:1 motor (at least the limit on our tuning ability, I am sure more can be ran)...
Larger turbine side on the GT35R is a plus ---- IE - larger turbine wheel... = less back pressure = more love from your high compression motor.
I run a Borg Warner S366 on my EVO IX - simmilar compression ratio - 10:1, 92 octane, meth injection, ECU flash, stock MAF, 20 PSI - just a tad under 500 WHP.
Great car - fun to drive.

10:1 compression ratio and pump gas = a lot of money spent on dyno time to make sure you do not go boom.

That is my personal opinion based on what I have seen here at the shop and on the dyno.

Advantages - pump gas hero!
Disadvantages - none that I can think of (I however am a huge fan of the 2.1l - so my opinions may be biased).

The most important mod for a big motor small turbo car is E.C.U based boost control...Or at least it was on my car...
Boost Taper was out of control with my MBC and EBC...
