FOSTA Posted October 16, 2012 Share Posted October 16, 2012 (edited) Im just about to start my second build, im picking another engine up this weekend and im aiming for around 600+bhp. this will be a build that i will be taking my time with as i want to do everything myself. so my question is whats my options in gearboxes? i have a na autobox in at the moment but that is already being pushed near to its limits. would a tt auto box be ok for 600bhp? (im thinking not, but unsure) ive been looking at a 6speed but is there any outher options? thanks in advance FOSTA Edited October 16, 2012 by FOSTA (see edit history) Quote Link to comment Share on other sites More sharing options...
hodge Posted October 16, 2012 Share Posted October 16, 2012 A stock autobox won't hold for long at 600hp. It's either a 6 speed or a rebuilt/upgraded TT autobox. Quote Link to comment Share on other sites More sharing options...
safcdixon Posted October 16, 2012 Share Posted October 16, 2012 Tt autobox with a couple of coolers would probobly be fine dude im sure whifbitz had a tt running that Quote Link to comment Share on other sites More sharing options...
Chris Bailey Posted October 16, 2012 Share Posted October 16, 2012 I remember Lee saying he had a Stock autobox with 2 coolers that run 700bhp, He turned the boost down so that the autobox didnt get cooked lol. Im sure if you put some oil coolers on the gearbox then it should be okay with 600bhp. Quote Link to comment Share on other sites More sharing options...
haz182 Posted October 16, 2012 Share Posted October 16, 2012 my current single is running about 550/600 on the stock auto box with cooler.. been going for 16k and still pulling strong.. Quote Link to comment Share on other sites More sharing options...
Noz Posted October 16, 2012 Share Posted October 16, 2012 R154? I looked at 350z gearbox's back along, but a waste of time. Maybe another car's gearbox. With the variation of gearbox's on the market and the ability to get custom prop's and bellhousings adapted, it seems crazy there isn't a box out there cheaper than a 160 that coud be used/ Quote Link to comment Share on other sites More sharing options...
tooquicktostop Posted October 16, 2012 Share Posted October 16, 2012 Speak to Ryan, he can map the torque down to protect the auto box, you should be find with a couple of coolers, leeP is also doing some built stock boxes at a good price these are set up for very different power levels I would have been tempted myself, I miss the auto a lot of the time Quote Link to comment Share on other sites More sharing options...
thetrashcanman Posted October 16, 2012 Share Posted October 16, 2012 Can buy my V160 box if you want nudge nudge wink wink etc But yeah I have heard the TT auto box's holding 550/600 going on for years, safest option is really a V160/161 box but depends how much your willing to spend. Wouldn't bother with the R154 option either, it works out almost as expensive as going for a 6 speed in the end really, so what's the point?

Kaan W Posted October 16, 2012 Share Posted October 16, 2012 Get a built auto like me I wouldnt like to think about replacing the clutch every so often with a manual and also how the auto box just keeps pulling its crazy! Quote Link to comment Share on other sites More sharing options...
HadeS Posted October 16, 2012 Share Posted October 16, 2012 Here in Poland we have a lot of drifters who puts BMW gearboxes and running 5/6xx HP. I'll be fitting one in my car (Getrag 260 - 5speed). As soon as my car will be running I'll be able to give some feedback. Quote Link to comment Share on other sites More sharing options...
abtin90 Posted October 16, 2012 Share Posted October 16, 2012 Dr Jekyll has one of David P's hybrid autoboxes for sale and if I remeber correctly it managed to hold over 500 lbs of torque fine on his setup - - - Updated - - - Here in Poland we have a lot of drifters who puts BMW gearboxes and running 5/6xx HP.

FOSTA Posted October 16, 2012 Author Share Posted October 16, 2012 (edited) Oh I didn't think the TT auto box could manage that sort of power that's fantastic news. Yeah I knew it would require extra coolers but that's easy to sort out. I'll do abit more research then I think I might start looking for a low mileage TT auto unless a 6speed comes in at a steal Thanks guys Edited October 16, 2012 by FOSTA (see edit history) Quote Link to comment Share on other sites More sharing options...
Supra N_A Posted October 16, 2012 Share Posted October 16, 2012 like said before.. tt auto box with coolers! Quote Link to comment Share on other sites More sharing options...

I'll do abit more research then I think I might start looking for a low mileage TT auto unless a 6speed comes in at a steal Thanks guys As long as it's mapped properly to drop the torque you shouldn't have a problem with the power your looking at (obviously combined with coolers) Now the autobox is a little more reliable (or should I say the limits/weaknesses are really known) I'm tempted to keep my auto when i go single as I love it (despite me having a 6 speed waiting to go in lol) Quote Link to comment Share on other sites More sharing options...
