soarer twin turbo engine into n/a supra ever been done

[garethr]

...... seems the gearbox in the manual Soarer TT is the same in the Mk3 Supra, but the Soarer sits further back. So if changing to manual, which would be best, an n/a gearbox or the TT Mk3 box?

I think that the difference between the Soarer and Mk3 'boxes is the position of the gearlever.

First point is that you would be very lucky to find either a Soarer or JZA70 R154 gearbox in the UK. Manual Soarers and 2.5TT Mk3 Supras are very rare over here.

Secondly, the 3.0 turbo Mk3 uses the R154, but with a different bellhousing (Bondango may be able to help you out with that), and there are lots of them about because Mk3s rust and blow head gaskets.

Thirdly, the W58 from a Mk4 N/A would be easier, but it's supposedly much weaker than the R154, and there must be some significance in the fact that Toyota didn't use the W58 behind the turbo engines. However, I assume that there are NA-T Supras running with the W58. so......

The mark 3 forum guys reckon that a 1.5 JZ is complete BS. The only reason they use it is because 2jz blocks are significantly easier to source than 1 jz ones.
