I've searched for an answer to this question, but had no luck. Would an H22A intake manifold fit in my car, and would the ports match up? The only questions even remotely similar involved an F22, not an F23. Thanks.

 

h23 bolt patterns line up with the f22b1

you have alot of porting and portmatching to do, along with the collant port between the head and manifold you will also need to run the thermostat housing and rear hard coolant pipe from the h23/f22a6 and a way to use them ITB's

good luck

ps : not justthe aforementioned but a large assed throttle body and a cam with decent profiles and higher compression (if you are not boosting) to take advantage of the tremendous air volume you have just introduced access to the motor

 

Grrr. What about an Audi A4, or A6 dual stage? Bda91acc brought that idea to my attention. One last thing, throttle body. Would it be better to use a Prelude throttle body, or get one specifically made for my car from, let's say, Holley, or Gude?

 

you can put a bigger throttle body but it would do you much good without proper porting, you know what i mean? if you want to get it done, get it done right and you'll happy about it.

 

Would a Prelude throttle body be sufficient? I don't know anyone with one on their F23.

 

we are working with golden eagle to bring a f22b and f22a intake manifold to the market before the end of the year, I would hate to see GE R&D bill right now but the new products coming out right now are kickass

Nothing for the F23?

 

well if I can track one down to have for a few months im sure we could have it made
