I'm putting together a simple car for a nice daily driver. 94 Talon, AWD, Auto. Block is going to be a simple 7bolt 2.0L with EVO9 rods/pistons. I wanna be able to get this car up on the converter as quick as possible, using a Holset HY35 turbo (same turbo as an HX35, but smaller turbine wheel/housing). Got a 4k stall converter as well. Plan is to run E85 as well.
My question is which head/intake will deliver the best results in terms of spool and overall power? Here are my options that I'm thinking.
1. 2G head/EVO3 intake manifold. Proven combo. Pretty much bolt on and go.
2. 4G67 1.8L head + 1G intake manifold. 43cc combustion chamber head increases compression up to 9.3:1 with the EVO9 pistons. However, this head has the 1G "big" ports and will require the use of a 1G intake manifold. Will the big ports and 1G intake negate the higher compression/quicker spool that the smaller combustion chamber offers?
3. 4G61 head from the 1.6L crowd (Summit, Colt, etc). They have slightly smaller ports than the 2g head (but seems like some simple port matching would suffice), have the smaller 43cc combustion chamber, and I can use the EVO3 intake with it. However, there isn't much info on 4g61t.org when it comes to swapping their 1.6L heads onto a 2.0L motor. Usually it's the other way around. Our head on their block.
I'm not trying to re-invent anything here. Just trying to make the most out of what's available OEM on a budget. I'd like some more input from you guys.
