'89 Supra 1jz auto to 5spd question

mikemc69 · 06-08-2010, 12:28 AM

New to the Supra world and still learning things about my car, not new to rebuilding engines and have done a 5spd conversion in my mustang.
I just got a '89 Supra with a 1jz twin turbo jdm engine and trans. The swap was done perfectly, only mods are.. New intercooler, 3'' custom exhaust from downpipe, intake, and bov... plus quite a few appearance items such as 18'' wheels etc.

My question is... I found a complete '90 supra, NA engine with a 5 speed. Can I use this tranny with this jdm engine, if so will I need any additional parts? I know autos are better for building boost but still going with a 5 speed.

Thanks in advance!

Yes, you can....although I would recommend sourcing an R154 tranny instead of the W58 on the NA. The R154 is more stronger and can take some abuse as well as high horsepower.

As for the necessary part, you will need to get a bell housing, W58 or R154, which ever swap your going to.
