There's a guy on eurocca.net who is wel into a project involving a heavily modified 2j and a e30. but thats going a bit off topic.
In reguards to the redtop, i have already pissed off the butterfly's in the manifold. once i get it all in, plated and running ill certainly look t a low mileage silvertop, or maybe build one up outside the car with forget internals and that.
