Which Cylinder head?

[Andrew7dg]

Just to warn you I love talking about engine dynamics, so please if you are going to suggest one, back it up with a reason. I know this has been talked to death but I don't think I found an answer to this question.

I am figuring out which head should I go with, the 1g or the 2g. Reading DSM tuners and vfaq, I am confused on what I should do. 1g has bigger intake ports. However there hasn't been any test done to see if that actually helps HP. It is just an assumption by people just comparing the intake ports. There are a lot of people throwing 1g heads on 2g engine blocks. There maybe some proof but it could be false proof by the difference in cams between the 1g and the 2g. However there has to be a reason why the stock 2g cars (215 hp) are making more hp and tq then the stock 1g (190hp).
The 2g head has a better angle for the air to enter onto the intake valve, which I heard is better then having the bigger intake. This has been sort of proven with the evos still having the same intake size as the 2g. And they are making good horse power yet. The 2g is also built with better metal then the 1g. My guess is the 1g does better in the higher RPM. However this car is only going to see the max RPM of 7500 so is that really considered high rpm on this car or does that mean going past redline...

what do you think I should do? I value any opinion I get.

The other question is how much will this actually matter. Will I even see much of a difference? When people run their cars on the dyno, it seems like they only look at max rpm but I am going to be looking to see what I am making in the lower rpm as well in the higher rpms.

I should probably mention what I have planned for the car so that better advice can be given. I am not building a High HP car. I am looking for good responce from the engine and the turbo from across the rpm range, not just the high rpm

I am going to go with the 1g rods with 2g pistons so I can have a compression of 8.5

I am building a MegaSquirt system to play around with (I am a DIY type person so I enjoy any chance of building stuff) The MS system is going to take over the stock ECU. I will have full tuning capabilities, also a wide band will be purchased for tuning. Going to go with MAP

255hp with a Aeromotive FPR (bigger injectors are going to be purchased soon, I don't know how big)

FMIC with hard pipes

3" exhaust system w/o cat

built my own boost controler

ACT 2600 clutch

Leaving the transmission stock (was rebuilt 10,000 miles ago)

Evo 3 exhaust manifold

Haven't figured out what turbo yet...

I want to go to E85 for the 108 octane so I won't be dealing with knock but still a little confused on what I need to do to the car to make it compatible. Where should I go to get the fuel rail treated?

Anything else I am forgetting

Spring is comming and I want to get the DSM out very soon!!!
