12SecTPIguy

I am looking to install nitrous on my 92 Z28. I have forged pistons, rings are gapped for nitrous, and am still running a stock runnered TPI. I have siamese ported the intake, ported the stock heads and it runs 12.7 @ 107mph as it is. I want 11s. How much does it need to get their and which brand is the most reliable.
Thanks in advance,
Charlie

Wizards of nos kit, better quality and features by far.
U.K based of course, but worth getting,
used other makes before and not as good.

Of course, because its not american nobody here will be
up on them and tell you otherwise, but you pays you money.....

When I ran Nitrous on my IROC, I used the NOS kit. I think it was part #5252. It's a wet kit, which most prefer over the dry kit. Installation was a piece of cake, and boy did it wake up my car. With the 150 jets, I went from 14.40s pretty much bone stock to 12.42/111 with no other changes. So, i dropped 2 full seconds in the 1/4. Your gains won't be that drastic as you already have mods, but I would expect at least a 1 second drop, maybe abit more, assuming you can hook. Hope this helps you out.

Do it properly tho.

Go progressive.

A large fixed hit is NOT any good for your engine, trans or diff.
Use a progressive controller and you can run a larger shot,
safer( far less likely to break things, which is what nitrous earned
a bad name for) and be quicker down the 1/4 mile too.

Wizards of Nos kits use solenoids that are designed to be pulsed,
all others will wearout and need rebuilding fairly regulary.

Bottles also use a safely release valve instead of the silly blow off discs.
These are much safer, just relieving pressure slowly as it needs to,
rather than just blowing and losing an entire (expensive) bottle of gas.
NOt to mention the occasional failure of blow off discs that have destroyed
a few cars over the years.

Youd be different too, not many in the states would have these.
