SR20 turbo exhaust on a 240 that still has a KA24 (before getting the SR swap)? - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

if i have a 240sx that still has a KA24 in it...

and if i dont get the SR20 swap until later
and for some reason i can get a turbo exhaust system that is made just for the SR20
(the HKS hi-power for the SR20)
http://www.hksusa.com/sr20det

is everything good or are problems going to come up?
(if i put that sr20 turbo exhaust system on a 240 that is still running on a KA24)
before doing the SR20 swap

you might ask why im not waiting to get the swap first but i can get the sr20 turbo exhaust now for cheap
from what i seen from searching the thing thats different is the diameter
how would it run on a nonturbo KA24 240sx ?

It was shown a lonnnnnnnnnnnnnnnnnnnnnng time ago that even NA KA's like 3" exhausts.

It works perfect but it will be a lot louder with the KA than the SR...
I'm running a Buddy Club Spec 2 80mm turbo exhaust on my stock KA...
With my SOHC KA, I ran the stock cat but with the DOHC KA I'm running a 80mm SR downpipe, cat delete, and then the exhaust... It all bolts up...

and here is an old post where Alex dyno'd before and after with a 80mm exhaust on an NA KA... it made more power throughout the entire powerband...

The Hi-Power exhaust that you're looking at is still pretty quiet on a ka. A buddy of mine had one on his s14 stock ka and when he floor'd it you can hear the intake over the exhaust. The resonator on the Hi-Power is pretty large and isn't quite straight through so a loud exhaust shouldn't be too much of a concern like Nike's BC Spec II.
