I just got my Holset H2E I bought (used) and it is in the basement ready to go! I just need to get the adapter plate to bolt it to the manifold and weld up a downpipe. It came with a short piece, about a foot long of 4" downpipe, that I need to weld a piece onto. I conveniently have a welding class on saturday where I can probably do it. BIG horsepower here I come!
