What's up everyone!! I have a 91 Dx with an Si cam and a basic intake,but I need more!!! I have been thinking about swaping a Z6 head with MPFI to get a good boost in power but my D15B2 has 160k on it. Will my Motor hold out with a high reving head on it or should I just swap the whole Z6? My budget is limited so I'm trying to get some good power on a budget.... Any advise would be great!!!!!
