BPU mods are horsepower-related only. Suspension is a separate category of modifications.

Pardon me for correcting you, but it's not really an RZ till the calipers, full ABS system, and differential are upgraded too. All of these SZ components are significantly inferior to the RZ/TT's.

Hmmm....could you provide supporting documentation for that? US-spec Mkiv's had 4-piston front brake calipers since '93.5. I find it very strange that 'yota would have short-changed the JDM TT like that.

1) What is a "racing" brake pad? Sounds pretty subjective if you ask me. 2) There's no substitute for a bigger rotor. 3) (And most importantanly) there's no substitute for a 4-piston brake caliper over a 2-piston.

Disagree. For what it's worth, I would not roadrace a ~3500 lb. Mkiv Turbo with n/a brake calipers - I honestly believe it would be dangerous and stupid (even if the pads were hand-crafted by Zeus himself).

Again, please provide a link to support this. In the US, the '96 Mkiv TT was actually downgraded from quad independent ABS to triple independent ABS (rear wheels use same ABS valving post '95). To me it seems highly unlikely 'yota would downgrade the US ABS the same year they upgraded Japanese-spec ABS.

How do you know he's not, if this wasn't in the list of modifications?

Disagree, imho.

I agree with you that the mods that are on both Supras were chosen with some degree of forethought, and may very well have been installed properly. In fact, a few of the mods are downright impressive (eg. the Ohlin shocks). HOWEVER: I do disagree with the subjective interpretation of the overall results, since the '93 won't be a full TT/RZ until the transmission AND differential, calipers, and ABS system have been addressed ... and the '95 won't be full BPU until it has a downpipe and some way to raise the oem boost level.

If I had to pick one of the two based on what you've posted, I'd go for the 93.5 TT 'almost-BPU'...assuming the prices are fair for both. With the '95 SZ->RZ partial conversion, you'd still be getting an n/a Mkiv with a transplanted engine, and too much $ put into the suspension for your application (just assuming about your application - please let us know what it is), imho.
