it certinly doesn't look simple. Hrm... How big is the turbo? i've never held or seen one in person. How does the FD primary compare with a S5 TII turbo?

Both the primary and secondary turbos are the same size. They are Hitachi ht-12's. The TII turbo's are ht-(something largers). You can use one of them (fd's) on a turbo project if you wish. You will have to make a turbo to manifold flange as well as a turbo to downpipe flange. I'm sure you can mount the wastegate actuator on there somewhere and get everything to work. I disassembled a set of twins and am using one of them to slap on a crappy old honda and see how it works. I've had a lot of spare time on my hands lately

One from a Volkswagen TDI should be easy to find.

Thanks for all the suggestions, but i'm looking to find the smallest turbo. The engine is only 470cc kawazaki Z400 with big bore kit.
