So far the W58 is okay, but I know it's on borrowed time, just waiting for the crunch/bang

 

Not sure what I will do when/if it goes, can't warrant the cost of a V160/V161, so may go Auto

 

Same problem I had Rog. When mine popped I was all for getting a V16* and even had one lined up, but other problems that were previously hidden chewed up the budget :( I ended up having to go w58 again, which took me and Paul 2 months to source :shock:

 

Even W58 boxes are getting scarce these days. If it goes again, I'll be looking at R154, as they seem to be the most readily available (still scarce though) conversion available. Might just fork out for a MKIII complete, strip the conversion and break the rest. Unless a V16* pops up at the right time.

Yeah as said Jon, I am seriously looking at the Auto route, I can't be bothered trying to get all the bits together to make a non MkIV Supra Gearbox fit

nice figures mate , 30hp loss from fly to wheel power is that right I lost around 100hp at ssr

 

That's already been asked and apparently 7.5% is the expected loss, so it's about right

 

In all honesty I am not up on this sort of thing, so rely on others for the info
