Jamesy Posted May 11, 2011 Share Posted May 11, 2011 Its the torque the will kill the box mate, 500-550ftlb is the limit mate. If u want big power u gotta gdt a boostlogic or similar in there with a high stall. Something like a GT35R is perfect with stock box If u go for 500ish power you'll be fine. Even if it breaks u can get a stock autobox for peanuts these days Quote Link to comment Share on other sites More sharing options...
JamieP Posted May 11, 2011 Share Posted May 11, 2011 Size of the turbo means nothing, its how hard you run it that counts towards how long the box will last, keep it to 500/500 and you may be ok for a while. Quote Link to comment Share on other sites More sharing options...
Rob_Mitchell Posted May 11, 2011 Author Share Posted May 11, 2011 yeah so just best i stick with a 62 then, i want something that looks big too but not too laggy. I have done my fair share of research and narrowed my search down to nearly ordering the s362 bw, but just want opinions as its not a cheap mistake to make... and the 72 makes me smile when i see the size but way ridiculous for my aims???

JamieP Posted May 11, 2011 Share Posted May 11, 2011 You can fit any size you want Rob, just cap the boost, for the most the bigger the turbo, the slower it will spool, although a lot of the new billet turbos spool extremely quick. Quote Link to comment Share on other sites More sharing options...
Nic Posted May 11, 2011 Share Posted May 11, 2011 Something like a GT35R is perfect with stock box Agree, the GT35R would be perfect with the stock auto box, for everyday use at legal road speeds it'd be difficult to beat. Quote Link to comment Share on other sites More sharing options...

Josh Posted May 11, 2011 Share Posted May 11, 2011 How come you won't upgrade the gearbox? Just get a built 'box if you want an auto and lots of power/big turbo. Quote Link to comment Share on other sites More sharing options...

Nic Posted May 11, 2011 Share Posted May 11, 2011 its knowing when the boost will come in though aint it? if i go for a 72 then would it spool different from a manual-auto? At lower boost you won't get the best out of the bigger turbo, a smaller turbo at a higher boost pressure will be far more responsive. On a manual with more gear ratios to play with you may be able to live with it but I'd imagine on an auto it could be a bit of a PITA. I'd fit a 61/62mm turbo to start with but future proof the ancillaries to support a bigger turbo, then swap turbos when you get the gearbox sorted.

sdistc Posted May 12, 2011 Share Posted May 12, 2011 PM Krister on here - he used to run a BL built box on his Holset 70mm and drove it very hard, so he will be able to give balanced feedback. Quote Link to comment Share on other sites More sharing options...
