Hmm everyone doing something big while I do small stuff that I probably shouldn't even bother mentioning...but I will do anyway
I replaced the parklights with white LED ones to go with the xenon lights
Pretty sure you can a BMW 335i for around 30k mark and that's a nice car twin turbo as well which gives you decent amour of power and pretty smooth on the road
but not as fun as a skyline would be
Do you have a BOV on it? Sometimes if they don't close properly after a boost then the car would not accelerate and keep stalling, it would also sound like there is air leak
You will need a bonnet and bumper, I did mine, my advice is save and get carbon fiber bonnet instead of fibreglass, this is my car after the conversion, the parts I got from carmate,
