What up Honda-Tech. I have an old school drag manifold with matching 2.5 downpipe and turbonetics turbo. Turbo is turbonets 57 trim .63AR. Turbo is setup for 5 bolt downpipe but one of the holes was stripped so it looked like the previous owner filled the stripped whole. I downpipe does have a few dents in it but it did not seem to affect performance. I ran this setup like this for years and never had any issues. Also, the bolts holding the turbo to the manifold seems pretty tought to loosen, so I am going to leave everything assembled. The turbo has a little shaft play but boosted fine for me. Turbo only was run off wastegate (7psi) the entire time i owned it. It will not come with the return line. I will take 225 shipped for turbo mani and downpipe. I also have a tial gate that i am looking to get 120 shipped for. I know the cast drag mani looks rough but it does work and does not leak.
