Read the latest issue of Turbo or Street Perf.(forgot). And there was this RX-7 with two turbos. Now you say,So what, all RX-7(3'rd gen.) come with two turbos,and you would be right, but this one had them piped in parallel, and one was smaller and had a diff. compressor so it would spool up in the lower RPMs and the other kicks in later. My point, can similar set up be mounted on an L28 with wastegates tuned to diff. pressure to allow this split. That way there would be no lag, and you could run higher PSI's. Or the weight of the piping will render the set up useless?
