Howdy, Jay here. Im getting different answers about if it's worth doing due to compression. Ive been told by 1 mechanic that i need to change comp otherwise wont get much boost. Cost 20 k. 2nd opinion from performance workshop is that the RB30 has alright comp to just bolt on a turbo and run up to 10psi. I need to know if I need to rebuild engine? It's in a manual Gq wagon. 91 model. Any advice would be appreciated,
Thanks .
