50 shot Nitrous on 57 trim

[ShadeTreeDSM]

Got a 90 GSX. 57 trim, DNP tubular manifold w/ 40mm tial, 3" full exhaust, Rebuilt stock motor, bored .020 over, ARP everything, cometic head gasket. walbro 255, FIC 880 cc's, and Aeromotive FPR.


getting it tuned in a few weeks and wanted a little quicker spool up time since its a street car. was thinking 50 shot. thing is i have the ZEX dry kit, dont know if that would be smart to do. should i get the fuel & nitrous solenoid from a NOS wet kit and just use that ?

or should i not even use NOS at all..


tell me what you all think

I have a 57 trim and used my NOS kit for the same thing, If you run a 35 shot (by NOS's jetting guide) you will increase spool greatly! The only reason i don't have mine on still is my bottle is out of date andi need it hydrotested before the shop will fill it

Did you guys use a dry shot and if so what size of jet (like you said) did you use and any fuel enrichenment??? I am thinking of the same thing, a little shot and was wanting to do a dry shot. Thanks for any comments.

A zex 50 shot is rated at crank. So it is comparable to a NOS brand 40 shot. Dry is fine if u have the ecu adding fuel. If not I would do a smaller dry shot and see what the AFR is under spray with no fuel added.

Thanks thats what I was needing to know. Inject right before the thottle body?

A dry shot can be injected anwhere. Before TB or even before turbo. I would do before turbo to get the full chilling affect and one less chance for a boost leak.

Wise thinking....hate boost leaks. Glad I only have 4 couplers!!! Thanks for your advice!
