I need nos...!

[dylant]

Has anyone had a NOS (or similar) conversion fitted to an n/a Supra?

I think there are a few out there. But Insurance is a real killer. what do you want to know?
Direct/Multiport Wet systems are what you are looking for. 25bhp shot per cylinder....25x6...

I was also thinking about NOS a while back when I had a Celica GT4 up my back end, fast cars http://www.mkivsupra.co.uk/iB_html/non-cgi/emoticons/cry.gif But just recently purchased a sports exhaust, which does the trick of increasing HP instead http://www.mkivsupra.co.uk/iB_html/non-cgi/emoticons/biggrin.gif

Anyway here is some info on NOS for you, as a newbie I found it useful anyway http://www.mkivsupra.co.uk/iB_html/non-cgi/emoticons/wink.gif

Quote[/b] ]Nitrous comes in a tank and the systems are fairly cheap. The pressure in the tank feeds it into the intake piping. In essence it's a form of forced induction that just uses a refillable substance (n2o) to power the acceleration. It is dangerous to use it at a low RPM so often it is only activated above a certain RPM (often in the 2,500 - 3,000 range).

When you heat N2O to about 570 degrees F (~300 C), it splits into oxygen and nitrogen. So the injection of nitrous oxide into an engine means that more oxygen is available during combustion. Because you have more oxygen, you can also inject more fuel, allowing the same engine to produce more power.

Nitrous oxide has another effect that improves performance even more. When it vaporizes, nitrous oxide provides a significant cooling effect on the intake air. When you reduce the intake air temperature, you increase the air's density, and this provides even more oxygen inside the cylinder.

Also keep in mind there are different types of kits, wet, dry and direct port.

Wet systems
This system fires nitrous oxide into the cars engine along side the additional fuel required to make the power. These systems supply a nozzle for the intake that has 2 inputs. One for nitrous oxide and the other for fuel. Because fuel is being mixed with the nitrous at the point of injection we call it a wet nitrous kits.

Dry Systems
These systems do not have a fuel solenoid as the additional fuel is supplied by the cars own injectors. This means that at the point of injection there is only nitrous oxide, no fuel. This is why we call these systems dry nitrous kits.

Direct Port
Direct port nitrous oxide systems use 4 injector nozzles and are screwed into the intake manifold branch of the cars engine. One nozzle per branch.
