Which Cylinder head?

[iceminion]

Andrew, I suggest the 1G 7bolt head, as I understand it, it flows the best. And on turbo cars, flow is everything. I will go out to the garage and take some pics of both heads and post em later tonight.

The 2g head probably has better response when off boost, but comon, boost is life, go for alot of boost.

I agree with JET, I would go with forged internals, you wont regret it, the 1G rods are cast, and they can bend/break, and the 2g pistons are cast also, they can melt easier.

E85 - Let me answer this once and for all: you can run E85 in any car, all you need to do is re-program the ECU (or use an SAFC) People have been running E85 in cars for a long time with no problems, regular pump gas has 10% Ethanol, sometimes more.

I dont know why everybody assumes E85 will corrode the fuel system, it wont.

If I am incorrect on anything I said, feel free to correct me, lets keep the correct facts in circulation, not automotive superstition.

Have you read any of the other posts in this thread regarding port size and air velocity?
