Yes and no. For example, the BCC, cam gears, fmic and fuel controller would all be useful, but the downpipe would not be. Aftermarket single turbo kits position the turbo in a very different location than oem, so the connection from the turbo's exhaust housing to the downpipe is in a different spot. As a result, the single turbo downpipe has a different shape.

No. Again, as I already stated in my previous post, the oem block is good for 800rwhp+, and the oem fuel system is good for 500rwhp. Therefore, you would not need more internal/fuel upgrades to make 500rwhp.

By restricting airflow/boost to the oem wastegate actuator, which slows down its response, and therefore allows a higher boost level.

Only about 14psi, safely & reliably. Can't you get 93 in vegas?

Oh, I forgot to mention in my previous post that you can use a meth+water injection kit (instead of race fuel) to increase the net octane level, and safely raise boost.

What did you mean by "XD"???
Phil '94 Supra Turbo, 6spd, 'APU'+
Displacement is no replacement for boost.
Life begins at 30psi.

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
