i am not a hundred percent sure if turboing a first gen is like turboing a second gen, u will not be able to run stock injectors and fuel reg and get a good tune, the second gen takes a fourty lb injector, stock r 19, and a bigger pump torun decent, along with a fuel management system, such as MS...first gens may be alittle different, but i would rather be putting in a set of 200 dollar injectors, rather than a 350 dollar engine,(leaning out is a very bad thing)for one the injectors take all of ten min to change, and and engine can take a few hrs..... good luck

 

his turbo has an internal wastegate
