Swampy442 Posted October 20, 2008 Share Posted October 20, 2008 Ive been looking into fitting Supra CT12b's to my 1JZ head, I have all the kit, manifold, turbos etc. Does anyone know of a place that can adapt the 2JZ manifold to fit the 1JZ head, or the 1JZ manifold to fit 12b's or a new manifold? Thanks Quote Link to comment Share on other sites More sharing options...

bondango Posted October 22, 2008 Share Posted October 22, 2008 to use 2jz jap spec turbos on a 1jz you need 2 of the front turbos (with wastegates) from the 2jz - they will bolt to the stock 1j manifold. Rear wastegate control arm has to be reprositioned and welded, You need a Custom Y-pipe and DP fabbed. all stock 2jz piping also used. They will also be a lot laggier than the stock tubbies and some people who have done it got pretty bad surging. Quote Link to comment Share on other sites More sharing options...
