What is the best Brand 150 hp Nitrous Oxide system to put on my 1991 350 TPI motor and why? Thanks.

 

SEARCH. I would say either NX or NOS.

 

I would say NX cause they claim to actually put 150hp to the wheels.

 

I did search!!! Didnt come up with anything that answered my Question. Thanks guys! Anyone actually use the NX system on thier TPI?

 

I love my Nitrous Express system. It's an LT1 wet kit and i installed it on my 89 IROC 305 TPI car with no problems at all. I Started running a 75 shot, then a 100 shot, now I am running a full 150hp shot with success. 150lbs worth of nitrous at this level and it's just asking for more it seems I reccomend the same kit and I also reccomend that you get the safety items like the fuel pressure safety switch, the wide open throttle switch, the bottle heater, and the purge kit, and a remote bottle opener. It gets pricey but every little feature is well worth it. Foloww all of the directions in the kit and everything will work beautifully! I also just installed a digital nitrous pressure guage from nitrouskits.com or dynotune.com...forgot the name, but it works NICE Goodluck and keep it safe man.

 

i Love the Zex system but i can't use it on my carb'd car :-(

 

Thanks Auto! My only concern is how that Nozzle mounts in my rubber intake boot, that boot moves with the engine and I worry about the Nitrous spaying more on one side then the other threw the throttle body.

 

I see what you mean...

I ended up drilling a hole(don't laugh) in the MAF sensor on my 89 car and Plumbing it AFTER the hot wire and pointed at the engine but yours probably doesn't have a MAF so you can't do that. Your car has a plastic piece that connects the air box to the throttle body, right? Is that rubber or plastic? Either way that would be the optimim place to plumb the nozzle and aim it at the engine. A Proper sized hole(so it holds the nozzle tightly) and a good glue or sealant will keep you safe. Goodluck!
