extractors on a 4agze

[chris_85]

hey.

just wondering if a set of 4age 16v extractors would fit a 4agze, and would they be effective?? cheers

[gixer]

yes they will fit.

[chris_85]

will they do the job? will they be worth while?

[Otaku]

yes they will fit
what type of extractors are you talking about after market or stock ones?
I think all factory extractors are all the same (expect for the 20 valve)

[chris_85]

its a set of genie extractors, not sure if theyre 4-2-1 or 4-1

Will they be effective? Hard to say. It depends how they are designed and made.

What's needed for a ZE exhaust is very similar to what's needed for a GE exhaust, only it needs to flow some more gas. So if the extractors were good on a GE they will be fine on a ZE.

I know this isn't a GZE but recently dynoed a 4AGE NA then put some 4-1's on, in the mid range the improvement was neglible, at the top end it held torque a fraction longer about 800rpm so power was slightly higher, torque curve was nearly exaclty the same except for the slight hold at the top end. This was a standard motor so obviously gains would be noticed with further imrovements.

I quite liked my Genie 4-2-1s on the GZE which i had. Felt nicer by the SOP dyno than the stock set which i drove to the exhaust shop with. That and they didnt have the datsun-about-face design of how it went over the crossmember.

One the GZE i would get 4-1 as with Forced Induction you don't need the backpressure to help with power. Hurricane make some at about $400 last time i got some.
Just rem the 20v ones can be made to fit but they are for NA applications so i wouldn't recommend it.
