"There is still some fab work to be done. Most of it has been covered under "GT28" installation in search. You could call these "Budget" GMS 675-R turbos."
They go for $850 each. But ginn you were saying that its not worth doing DIY GT28 to fit Z32 before. Are you going to use my FAQ post to instruct your customers on how to do their budget kit or will you make your own FAQ here on installing gt28rs on a budget???
