The ignition coils are RSX COP (coil on plugs)
The intake manifold is a Edelbrock Victory Jr for an Acura Integra, we had one at the house along with an extra OEM manifold and noticed the runners lined up. So cut the flange off both and welded the OEM flange onto the Edelbrock also fabricated a flange for the mustang throttle body.
As for the Exhaust manifold, yes it is generally similar to Brians but only generally. The pipes are routed differently, the turbo is mounted differently. While I can't really see what kind of tubing his is made from mine is made from Schedule 40 Stainless steel. It's seriously strong. we actually lifted the engine out of the car with it (had to send the engine back to the machine shop cause they screwed up and hadn't notched the piston skirts for the oil squirters.)
As for the transmission well, nothing as of yet. but I'm seriously looking at getting the PAC gear set if they are still available. Otherwise my buddy was thinking we might be able to make an adapter plate to fit an RSX transmission. I do have the Driveshaft shop stage 2 axles.
But I also have the TurboXS multistage boost controller so will atleast be able to bring the boost on in stages so as not to shock the tranny as bad. Also as a stop gap measure I know where I can get a gtx tranny for cheap.
