did you advance the timing try 12-14 degrees also bring the TPS up to 1 full volt for better throttle respose,the timing adjust is good for about 5-9 h.p.

12-14* on nitrous? Isn't that dangerous?



Wait, nevermind, don't mind me. Thought we were on the nitrous subject still

Thats a good ? With advancing the timing and running the nitrous will that still be ok?

Start with like a 75-100 shot. If you like it as much as I did, Go up to 125-150 and get a regulator and a bigger fuel pump.

Erik92gt

What nitrous kit would be recomended since there are so many different options out there and what fuel pressure regulator is a good one to get?

lloydchristmas

I prefer to use strictly NOS stuff. Regulator you can get from BBK

If I was going to make any mods on a motor that didnt plan on being around for a while I would do things that would interchange with the new motor. Throttle body, intake, injectors, mass air, fuel pump, headers, etc... I did the same thing and it all worked out good for me. I have replaced everything you can imagine so if you would like an opinion of a swap I proabably have already done it. Dave

I appreciate the idea, the only problem I would run into with that is im not sure how everything is gonna match up yet with what im gonna be running. I plan on running a 306 that will be about 400hp itself with a ATI Pro Charger with about 14 lbs of boost, so thats gonna put me close to 600hp. I plan on going with an Aroemotive Fuel system. But as in the throttle body, mass air, injectors and headers, im not sure whats gonna match up with it.

yea ull need a bigger throttle body ,mass airmeter and injectors after u do that, i like ZEX nitrous system, easiest to work with and install

yeah on nitrous thats too much timing i think your suppose to decrease timing

now if your staying on motor then advance the timing
