I have searched and searched to no avail on several of these questions, some I have found, but others do not answer directly. First things first, I have a B16A in a 92' EG CX that includes: I/H/E, Stage 1 Clutch, A/F ratio gauge, 8lb Flywheel, Chipped ECU tunned on Crome. I am looking to stay all motor since curves and mountain road > straight lines. Emission tests do not matter where I live, so my questions are:

1. Will a 12.5:1 CR be efficient on pump gas w/ a good tune?
2. Will 84mm pistons be a threat to the block. (I dont believe it would matter.)
3. If not, will I need to mix 100 Octane race fuel, half and half, with 93 Octane (Available in TN).
4. What would be a large cam that would use the full potential of the motor.

Open to Suggestions:

1. Cam gears?
2. Buddy Club P1 Racing Dual Valve Springs?
3. Buddy Club P1 Racing Titanium Retainers?
4. Skunk2 Racing’s Pro-Series Intake Manifold?

 

well, you've got a few issues here:

1. It can, but with the right engine components. Just because it is higher compression doesn't mean anything if the components you use aren't right.
2.You cannot fit 84mm pistons in a B16 Block without sleeving it first, and even then, without the accompanying additional stroke to go with it, you won't see too much of a gain at all compared to 81.5mm
3.Again, fuel is on you and how you drive. some of us here are at 12.0-12.5:1 using 93 octane, with no mixing
4. That's where your reasearch needs to come in. you don't need a very large cam to do what you're trying to do. Skunk2 Tuner2s or a Pro1 would do just fine. But it depends upon the header and IM you're using. Don't get parts that are made for straight line racing (in the name of POWER) if you're running mountain curves aroudn

Suggestions.
1. anything but e-bay crap
2. sure
3. Sure.
4. Good idea.

BTW, I've done even better with my turbo honda on the "curves" and mountain than even my Hi compression NA car. its all in the build and purpose, not whether or not it is turbocharged or NA

 

thank man I appreciate your time and help, so this might be for the FI forum but your saying that I should maybe look into a low psi turbo build perhaps?....I run on HWY 421 (The Snake) and I just like the mountain roads in the fact that they challenge me back. And just wondering....is it practical to add weight in the rear since it is super light and squirly?
