my setup consist of..

- M24x's w/ associated valvetrain
- 1mm over valves
- hytech 2.0L header
- 3" exhaust which i will eventually be changing to 2.5"
- Mugen intake
- Wiseco 11.5:1 comp pistons
......etc, but thats the main things.

I was thinking the biggest bottle neck now is the intake manifold and throttle body. Next after that will be the head. Am i correct on this?

I plan to order a VictorX since everything else on the car is geared for top end as well as a Professional Products 68mm ITR throttle body. Or do you think the stock ITR pieces are sufficient?

 

with that setup, a victor x and a 68mm should work very well. especially on the top end.

 

If your motor is geared for topend i would go with a 72-70 throttle body with the victor x manifold because the tb will make your powerband more broad

 

may i know whats ur set up and the hp ur running current cos ur set up sounds like mine and i wanna check if i'm gettig power out from the m24x cam.

 

With the set-up you have already, if you're not going to invest in the victor x or tb, GO for the a CNC ported intake manifold and ported TB. You'll be extremely happy with just those bolt ons
