hits the inside of the car?

i would be looking at cleaning the AFM and replacing teh plugs ...

then get a mechanic to check your engine mounts.

So you got funds to modifiy and upgrade the skyline,.. but not maintain it?

I think you need to get your priorities inline.

But i would look at the AFM next since coil and sparkies are new.
