Has anyone here considered putting a supra 5 speed in their falcon? And has anyone had any quotes or does anyone know roughly how much it would cost? And how much horsepower are they rated to?

Thanks, Dave.

which model 5 speed are you looking at?

Why not fit a T5? (Original equipment for 6 and V8 with different ratios) Where did the idea come from for the Toyota box? The T5 is reasonably easy to find and fit and is generally robust.Later build ones- late EB on are better). SVO make a short shifter for the box that reduces lever travel about 50%- snick-snick. good stuff!

I investigated this as an option to upgrade the gearbox in my EL XR6 rally car. The concensus was that the Supra five speeds are rated to about the same as T5. The twin turbo boxes / 6 speed boxes are a lot stronger, more expensive and harder to fit, and if you had sufficient HP to warrent something stronger than a T5, then the tremec (and not the tremec T5 fitted to many late V8 Falcons, which is a regular T5 with a tremec badge) is the go. It's easy to pick the difference, the tremec weighs about twice as much as a T5, and is a lot bigger.

A T5 will do the job in a standard or mildly worked Falcon, unless you are really hard on the box. The I6 and V8 boxes are different, and can't be swapped.

I hope I have solved the problem in the rally car by getting a close ratio straight cut gear set put into the standard box. The first three gears are all about 4-5mm wider, so hopefully they will hold together. It's not in the car yet - hopefully will be this weekend.

Whiteryder, can't you please pass on the details for SVO - thanks.

What i found out was the Supra 6 speed that lives in the Twin Turbo RZ model is a German Getrag brand. It is a top gearbox but being made in Germany it'd be very very expensive.

I think the T5's are a good box, and relatively well priced.

Info on SVO shifter and pic up soon... Stay tuned...

There's two, the V160 and V161 - slightly different ratios. These gearboxes have the bellhousing fully integrated with the box (like a Holden Gemini), which means fitting one up is not as easy as getting a bellhousing made up to bolt it on. Castlemaine Rod Shop were getting one in to investigate making an adaptor. Price of the box alone, 2nd hand is a lot more than a Tremec.

Contact Mike Webb, SVO in Ringwood ph 98768586 re the short shifter. It cost me $375 fitted. It works very well, and makes the standard shift seem very sloppy. It's well made and should be reliable.

You can bolt a VS (possibly other commo's too) commo shifter (off their t5 of course) on to a Falcon one to give it a short throw feel as the shifter is shorter....

You can use a shifter out of an EA 6cyl as they are the same as the ones in the EL GT. They are visually different and it is a shorter throw.
