VP T5 to L67

[VK SL 3800]

Hi all,


Im building up a mild L67 for my VK and im wondering how well the old T5 will handle it, iv been reading mixed views on strength, some saying they break, other saying if being abused they break like when flat shifting but will be fine otherwise. Any one had any experience with them? Im contemplating going a T56 but the setups are really expensive and i already have the VK setup for a T5.

I dont abuse my car but i dont wont the gearbox failing when i give it some on the odd occasion.

Cheers Ben!

If the T5 is the same between V6 and V8 (im pretty sure they are), they can hold tons.. Mischa was running a stock T5 bolted behind a 355 and it went fine..

it has been done and works well

For a mild built that isn't 'thrashed' daily it'll handle it fine.

Sweet sounds promising, well i think i will run the T5 and if it does break ill go down the T56 route.

I used a T5 behind an Ecotec and had no problems with 12psi

I have heard second gear is usually what goes in them. The V8 T5 has a taller first gear and a shorter input shaft.

There are mods you can do to make them a little tougher, a billet retainer plate and shimming the bearings tighter - google it

as above the v6 t5 has a longer input shaft and shorter 1st gear. from what ive seen the box is fine as long as its not being flat shifted, also i hear slamming 3rd gear in particular is not a good idea

thats my old car. been running this engine and trans setup for two years now with no problems (it's in the Calais now) and i don't baby it around.

only thing i've noticed is that the box is getting a little noisy under high load, low revs, but nothing major...

This is good news, ill definitely run with it.

Thanks guys!
