Wow. Didn't realize questions were aimed at me. Heregoes.
228 whp is great but how much did you spend jeff ?
This is vague. Spend on what? Just the turbo setup (initially, I'm on KA-T v2.0) was $2200, but that was also 3 years ago, when RevHard's mani was one of two on the market, and was $650. And no fuel setup. I just drove KA-T automatic at 4psi for 20k miles on stock ecu/fuel injectors/pump and no intercooler. So comparing that to a current FMax is like comparing Apples and Shovels.
i'm not sure but if you check out jeff's 240sx you'll see that
it's a system that requires more than what is provided in the
kit
I never had a kit, as I pieced mine together. But FMU is a really poor fuel management if that's what you're saying. Go with what Matt is saying for fuel management. He knows his shit.
Is there a difference between Fmax, Xs Engineering, Greddy, etc? (Other than the fact greddy doesn't come with the intercooler)
FMax uses a log style sidemount mani on t3/4. XSE uses a RevHard and full t04b, like my setup. GReddy does have an intercooler option, and it's a VSPL with different hotpipe.
