Studioface, finally got my J37 tb installed with your 4"CAI.
Your tb is like mine with The allen screw tapping where The sensor used to be.

I have a bit of a problem, as im having a bit of rev hang, but básically my problem is The rpms jum a lot when rolling and neutral.

Díd The tb relearn procedure without results.

Any imput?

BTW, it breathes like a beast.

I am not really looking for anything thats too much aggressive thats why I am going with the A's but for drop in cams and seeing guys making over 20whp I think thats pretty decent gains.As for the intake system the theory behind it is the more availability the air is,the faster the delivery and given the nature of these k series they love to breathe.I am sure the intake could use some fine tuning but that would require multiple tests and data logging with a flow bench and alot of trial and error.
I just made it sampler by going bigger with less bends and less restrictions.

What about their S's the supercharged cam.

Currently at 250hp
I have a perfect setup to test this j37 on a non ported rrc. I have a k20z3 with stock bottom end
Hytech header
3inch exhaust
Rrc mani
J35tb
950cc injectors
Drag cartel 2.2 cams
Super tech vt

I'm very interested in seeing what gains could be had over my current setup....
Here is a link to my dyno results with j35+rrc

I would say the j37 and ditch that skunk2 mani. I have almost all same mods.

I have a question! I installed the the big bore throttle body but the bolts that came with it seem too short! I used my torque wrench to tighten them but it kept going in circles! I have all black bolts! Do i need the silver looking ones!
Any help at all? I dont want to run with loose screws!
