my 90 crx dx is rated at 92 hp. realistically how much hp would a good exhaust system snd air intake add?

 

5-6 hp maybe

 

You can probably get the same if not a little more buying a D16A6 camshaft and swapping it in along with a MPFI swap.

 

haha, yeah, not very much. i got the same motor in my car, it sucks, i know. take your time and build a motor. not sure what kind of money you have, but you can get an enging that needs rebuilt, rebuild it and have less than 500 in it. i'm building a d16y8 right now, and trying to get 250hp on nitrous.

 

this cam will swap right in? any smog check problems swapping cam and injection here in calif? dont need 250hp. maybe an extra 20 would be nice. i have a 71 chevelle ss w/500 ft lb. torque. and a gsxr 750. so my crx is my putt putt.

 

Yup, the cam will swap right in.
No problems with CA Smog; it's for the most part just like having a D16A6. They won't notice it's been modified just make sure you connect everything how it was to pass smog.

 

why are there so many threads just like this? lol

 

plus you lose bout 30% through drivetrain you want to have a fun single cam dd do multiport wit an a6 and get ya a good clutch and 7lb fidanza flywheel(or any light weight flywheel) its a world of a difference and it frees up alot of power your car doesn't struggle on the hills it usually does.... its a good investment....

 

I used to have a 91 DX and I put a Pacesetter cheapo cat-back on it and I actually noticed quite a bit more power.

6-8 HP on a CRX is 6-8% more power.
