Hf manifold or aftermarket
 

I have a 88 crx hf comming to me by next week and i was wondering what the benifits of using an aftermarket manifold over an hf manifold. besides the fact that i can run an external wastegate?

Re: Hf manifold or aftermarket
 

you can run external on the HF too.

Re: Hf manifold or aftermarket
 

And how do you go about managing that one?

Re: Hf manifold or aftermarket
 

cutting and welding a flange

Re: Hf manifold or aftermarket
 

If I am wrong I stand corrected, but the main diffrence is the hf's are more prone to cracking over a dedicated log manifold

Re: Hf manifold or aftermarket
 

I've seen more cracked log manis than hf ones.
california cx/vx and 96+ sohc manis converted to turbo manis crack all the time where the spark plug O2 sensor is.

Re: Hf manifold or aftermarket
 

Cali has spark plugs in the ex manifold? :o

Re: Hf manifold or aftermarket
 

he meant o2 sensor

Re: Hf manifold or aftermarket
 

hahaah! ya thats what i meant. :-[

Re: Hf manifold or aftermarket
 

HF's better than a log any day.. but better than a primo after market... probably not.
