Nitrus in a VW Jetta

[damnationover]

I was wondering if there are any dangers to installing the bolt on NOS 40-60hp import kit on a 1985 VW Jetta GL. Also any concerns I have to be aware of. I know a fair bit about engines but this will be my first modification.

thanx in advance

theres a chance of blowing a headgasket, because its an old car. Might be to hard for the pistons, bearings etc... is it cast or forged? Bearings will probably be worn out if its a high mileage car.


You have to increase the fuel pressure, new fuel pump is a normal upgrade, running lean (lack of fuel mixture) is usually when things blow up.

If i was doing this, i would try a small HP kit. And work on up to something higher. Unless its a beater car and you dont really care.

I am not sure if it is forged or cast ... the mileage is unknown ... it is believed to be around 250 .... the car is a beater car but I would like it to last a while ... I am returning to college this year ... maybe I will buy a del sol with a V-Tech and just wait and put nitro in it

Nitrous on a car or truck with a questionable engine is not a good idea unless you just want to play and don't care if you blow it up . START SMALL !!!

Rebuild the engine with Forged Pistons and better components. Get a stand alone Fuel system. if its a four cylinder you don't want to exceed the size of the shot by much. A brand new out of the box four cylinder is suppose to handle 75hp shot of nos. A very well prep'd four cylinder can handle 100-120hp shot. Maybe even more. Anypoo. I wouldn't risk nos on that engine. If i were you I would do the engine swap for a VW 1.8T engine and then upgrade the Turbo and then add NOS. Then yourcar will haul.
