W58 Or R154

[GST95]

I dont own a Toyota, but am considering one of theses gearboxes for a mitsubishi 4g63 powered rwd project.

I cant seem to find the info that I need about these boxes, so I hope you guys can help me out or point me in the right direction.

I dont need to know if it wont or will work. What I need to know is what is the max rpm will I be able to consistantly shift both of these?

I know the R154 is stronger, but what is the hp or torque limit of both of these?

The engine that will be used will probably be around 300-400hp and rev to 7-8k maybe more.

Do you think either of these boxes will work good with these specs, or should I look for a different option?

If there are any other PROs or CONs to either of these please let me know.

I think I already have a W58 (out of a 84? celica). Is there any identification marks on it to verify?

Thank you for your help.

If this is not the right place to be asking for this info, can somebody please tell me where I might find the answers to my questions?

If anybody knows of any links to other cars using either of these trannys with a similar engine (300-400hp, 8500rpm redline) that would be very helpful.

Thank you.
