thanks for all the replies from what have had done for searching i came up with this complete kit and not much else. granted the toyota injection would be awesome but from what ive gathered i need to swap the heads get a complete kit hopefully from the junk yard that has not been completely destroyed wire the thing in so far the system does not seem to make and power gains but im really just looking for the MAP sensor and to keep from floading out on hills. and does anyone know if a 82 exhaust header would work on the later year head? cause i just bought a header and i have a offenhauser intake manifold which i could use on the new system once again thanks for all the replies
