Expensive J-pipe when you don’t receive your order!The J-pipe and down pipe are where the real value in this kit are. These are custom pieces that cannot be purchased elsewhere and are definitely of better design and higher quality than the few alternatives out there (CX and Treadstone).
Having previously built my own turbo kit from scratch, with some success and some failure, this is a big part of why I bought the wits' end kit. It really is a superior product if you actually get it,
The turbo, wastegate and all the other bits and bobs can be cobbled together on your own with some patience.
:edit: just read about that HD Automotive kit for the first time. That might be a viable alternative for a similarly designed J-pipe and at least the beginnings of a downpipe.
Personally I would fabricate my own.
I’ve built turbo manifolds before for B series diesels in Cruisers. Several 100,000km’s later it’s still going strong.
I use schedule 80 weld-els.
