A couple of things, why are you using your old clutch? The FW05R comes with a clutch setup, a good one at that. As for Pull-start, you may have clearance issues so I doubt it's a way to go. As for the pipe and manifold, there are several companies that came out with this right hand side arrangement. Check out Skyline, Rdlogics, kyosho etc. You will get more information just by going thru the FWO5R thread. Hope this helps you get to were you need to go.
