i've done my reading and searching, The best source of info i found said not to bother if i had to ask as far as turbo applications.

I already have a wet kit, I'm thinking about running a 50 or 75 shot..
mods:full 3" exhaust, msd 6a, cone filter, hks pfc f-con, aftermarket FPR, walboro 255 fuel pump

all i want to know is if this is a bad idea. lol
good experiences/bad experiences welcome!

 

Few people do it on turbo Rx-7's, but not necessarily because it can't be done. The only two I can think of are Steve Kan and scathcart on this forum (search for his guide). I've messed around with nitrous on piston engines. Just make sure you've got a window switch. A bottle heater helps a lot too because without one the pressure will vary a lot with the weather and how much nitrous is in the bottle.

One thing you need to be careful about is overboosting. If you have stock turbo you may easily overwhelm the internal wastegate.

Throw some race gas in there the first time you do it. It's cheap insurance. I'd do at least 110 leaded. With a stock ECU and no form of timing control it's a little riskier.

 

stock turbo but the wastegate has been ported. and i've also read scathcart's writeup sevral times (he only covers n/a application), thanks for the info through!

 

The problem with nitrous on a TII is that it produces a lot exhaust gases for that tiny little wastegate. You'll battle boost spikes as soon as you engage nitrous no matter how big you port that stock wastegate. This is the reason I mostly only covered N/A engines. Its very hard to make good use of nitrous with a stock turbocharger, and with an aftermarket turbo, you can just as easily turn up the boost if you need more power without resorting to nitrous.

That's not to say nitrous doesn't have its place on a turbo engine. For massive turbo's, its excellent for building power until the boost kicks in, and the huge exhaust gas volume it provides massively decreases lag. As well, it decreases charge tempreature by a huge amount, which helps to reduce the chance of detonation, and helps to increase power.

That being said, I used nitrous years ago on my stock turbo TII with mild success, so it can be done.

 

that's exactly what i was looking to hear! thanks scathcart!
