my street car/daily driver is getting some nitrous love....
the car is an internally stock 1989 toyota mr2sc has the 4agze motor in it...its a 1.6 rated at 145hp...it comes with a a/c compressor like supercharger that i now have wired on a switch...

car has usuall boosted mods..header/exhaust/intercooler and porting of the supercharger...


the car has wierd intake track...
it starts sucking through the af then too the tb that is not mounted on the intake manifold...it then goes through the supercharger and into more pipeing too a intercooler then too a inlet port on the intake manifold...

im wanting too run a 50shot wet into the car...i know the benifts of spraying pre supercharger but thats alot of pipeing and im thinking it would go lean...im thinking the best placement is about where i have it?? i want opinions and theorys thanks...

Where is the nozzle located? pre cooler, pre throtle body. People will recommend that on boosted vehicles that the nozzle is after the cooler and before the tb.But in your case???????
Nice video. sounds like everything was working hows it feel?

the car feels great....if you look in the pics you can see my nozzle is very close too the manifold...it's after the tb and intercooler...if i spray the car befoer the tb it will be taking fuel and nitrous through the tb/supercharger/intercooler and all the pipe literally like alot of distance...im sure it would be bad like that...


i was thinking about spraying fuel at the manifold where it is at then spray nitrous pre intercooler for better cooling but it might puddle fuel doing that i may just leave it how it is...plugs and timming look too be on the safe side and it feels good...

You're doing it right. Don't spray through the intercooler or charger, that's not ideal and can be dangerous.. The manufactures always say 6" or so from the TB, but on a car that use the TB before the supercharger that's wrong. Some cars with Eaton blower have no choice really, since the charger basically is the intake.

You want it close to the engine, but not so close it's only going to make it's way down 1-2 runners. Far enough back for good suspension in the passing airflow before any individual cylinder runners. I'd say your placement is perfect!


Nice MR2 by the way, I've always had a massive crush on those cars. My step dad had a N/A one back in the early 90's, and I have fond memories of it.
