I'm wondering how much NOS can you use in an 87 rx-7 with 160 miles. I was told mey engine was rebuilt by one of the previous owners but I'm still not sure but if I have a good compression ratio how much NOS will suit my car best.

 

instead of everyone answering this question, it would be nice if you just did a search because we just answered this question.

 

***... no love at all...

 

sorry. but really, intead of everyone wasting their time answering it again, he can look for the one we just answered. i dont mean to be mean.

 

I will answer this:

If you are not positive that your engine is in good shape then your car can handle NONE, ZERO. You need to get a compression test then go from there. Get your car as close to 100% as possible, then go for a 50 wet shot.

 

if you have good compression, on a turbo II w/ a 50 shot, you could easily see up to 60 RWHP. Just make sure your fuel is up to par. being Fuel pump first and the bigger injectors. It's a great upgrade for the dollar. Do your baisc mods first, and you'll see really good results. Good luck ....

 

why not direct port?

 

Wet shot seems like a safer way not to lean out. With a 50 wet shot or so you won't have to upgrade the injectors or fuel pump. Contact fc3s.org on here.

 

ohhh ok. so whats the difference between wet and dry?

 

wet dumps fuel as well as NOS. Dry only dumps NOS

 

oh ok. thanks.

 

Right, a wet shot of N2O will add both Nitrous Oxide and more fuel into the engine, so it makes it safer for the engine. A dry shot will only send Nitrous, and is a little bit tougher to tune and a little more dangerous if not tuned correctly.

www.JimWolfTechnologies.com sells aftermarket computers that incorporate two modes: one being for spirited driving, the other being for the same but with NOS. It's set for a dry system and the injectors compensate the extra fuel needed. It's really nice and with the flip of a switch you can turn everything on. I wish someone made something like that for our cars.

Direct port would B a bit hard to tune even with an AFC you would need more flexibility, so something such as a wolf 3D or Haltech would have to be used.
