I just bought a Zex nos kit for my 93 RX-7 with a Apex IHI turbo kit. I have a f-con that works great with this set up. The power is good, but not great. How risky is installing this kit? The engine is new from japan with 4000 miles( witha street port). With the smallest jet (55HP) what are the chances of blowing my new engine?

If anyone has any experience with nos, please let me know.

PS I was thinking of spraying it on my Peter Farrell intercooler if it is to risky(is that bad?)

The intercooler choice won't really make any difference with the nitrous. I would make sure you handle on your A/F ratios on just turbo first before you use it.

the A/F are good for the turbo

keep it low 11's high 10's.

If you got enough fuel, the amount of NOS shouldn't wear on your motor all that much. Unless you use it at every stop light.

Lets see.... NOS stands for Nitrous Oxide System, and you have ZEX... So you probably won't be shooting NOS into your engine :-p

Spraying "nitrous" on your intercooler could improve its cooling over the ambient temperature, thus decreases the chance of going into detonation. Make sure you don't spray "wet fogger mixture" onto a ignition source.

If your air to fuel ratio is within the safe margin, you probably won't blow your engine from the ZEX nitrous system. ZEX systems uses a computer controller to increase fuel mixture so you should not run any leaner than what you are already running.
