jorre 0 Posted December 8, 2006 what is the best gearbox that i can fit under my T16 engine? I have a gti-6 gearbox, but i have heard from people that it isn't a good gearbox because they aren't strong enough for under a T16. Some more info. My T16 engine is home build. So MI16 with lowered compression, tb's and gt28rs turbo. Share this post Link to post Share on other sites
Daz_C 8 1 Cars Posted December 8, 2006 Hi I know its probably not the same power but I'm using a 6 box with quaife atb pushing over 200bhp and had absolutely no probs with it and although not so much now (old age and conscience ) it has had some serious ragging in the past I'd imagine the amount of torque you will be pushing will show its weakness if any but i'd imagine the driveshafts will go before the box but hey what do i know Share this post Link to post Share on other sites
Miles 331 1 Cars Posted December 8, 2006 The cut of the gears (Helical) isn;t as deep or strong as the 5 speed boxes, Even the Race ones I know sometime use the std gear set's and I've only seen 1st gear weld onto the output shaft, Yet I;ve seen and had a few 6 speed boxes with striped teeth. So a BE3 5 speed box to suit your needs Share this post Link to post Share on other sites
28CRAIG 2 Posted December 8, 2006 Did Jamie Tonks ever have any problems with his if that was fine i am sure yours will be. And seen as you have got one you may as well use it and see how you get on. Share this post Link to post Share on other sites

357 0 Posted December 13, 2006 I use a Xantia 1.9TD gearbox. Hi I use an S16 fitted with T16 pistons and running 2 bar boost and my GTI-6 box is still the same as I got it 2 years ago. Maybe my wheels spin too much and this reduces the load on the shafts and gearbox. Share this post Link to post Share on other sites
jorre 0 Posted December 13, 2006 i'm going for a diesel gearbox. I don't want to take the risk of using the 6box and after a few miles build it back out. And i'm definately going to have a good LSD. Share this post Link to post Share on other sites
cybernck 402 1 Cars Posted December 14, 2006 if you ever get too wild with power, to get most out of it use mi16 gearbox with diesel (~3.4) final drive . Share this post Link to post Share on other sites
