Well here is my winter mod list what else should I consider.

52 or 58mm Throttle Body (which one?)
30lb SVO Injectors
Holley 255 lph fuel pump
Electric Water Pump (Meizere or CSI?)
1.7 Rockers
NX Wet Kit

What gains should I expect from these mods, excluding the NX kit. I know how much it will help.

 

Ditch the TBs....been discussed a ton and the overall consensus is that it doesn't help. What size RRs are in now? 1. 6 or stock>

 

I currently have the GMPP 1.6's. here is what originally got me thinking about getting the 1.7s

I have read a someplaces that a tb helps and someplaces say it doesn't. I will research further before buying though. Thanks.

 

The throttle body and the injectors are not really needed. The fuel pump is good for the juice. I would spend the other money on a controller so you can get the most gain from the n2o

 

youre gonna need a good ignition setup with timing retard capabilities for the gas. junk the throttle body and 30#ers, you dont need them. spend the extra money on an MSD digital 6+ with launch control and adjustable retard. youre also gonna need a bottle warmer, prob gonna want a purge kit, blow down tube etc

theres a lot more to it than just buying a nitrous kit

 

Thanks for the n2o advice guys but I have had it on my old Formula and already had it on this Z28 but removed it after the cam install, so I know there is more than just putting on a nitrous kit. I already know what is required for that, but Thanks anyway.


That is why I am going to put the fuel pump and injectors, the injectors may not be needed but I would rather play it safe. Alsoas far as ignition I have an MSD 6A on the car right now.

Now are the electric wp and 1.7's worth the price?
