first never used nitrous and never sill if you need it you dont need to be racing
second everyone i talk to says that the mk3 isnt a good shell to build on better is mk1,2,4,5,6,
so mk3 is out
but yes i thought about rear mounting the r32 into the mk1 or 2
and be ok dont know yet still looking into thoughts and plans it might be just as easy to buy a mk4 5 or whatever and just weight it out for the strip
