Gambit Posted September 7, 2015 Share Posted September 7, 2015 As said above [emoji3] But will need a good strong box and matching diffs. Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted September 8, 2015 Share Posted September 8, 2015 Clutch control. I'll make a mess of this but it was explained to me: put your hand 6 inches away from a wall, now push as hard and quick as you can. Do it again but this time have your hand touching the wall to begin with. Find the bite and feather it in to gear. Takes the strain off the gearbox. https://youtu.be/ZlFHY_U22Jo Quote Link to comment Share on other sites More sharing options...
Darren1970 Posted September 8, 2015 Author Share Posted September 8, 2015 i was hoping to see about rebuilding my box with maybe stonger internals if they do them, ive drag raced bikes for years so this car thing is new to me Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted September 8, 2015 Share Posted September 8, 2015 If you have a TY752 gearbox you could look at getting a TY754 with matching diff. They seem to have a reputation of being stronger. I may be having my gearbox rebuilt soon and I should have a price today. I'll let you know the outcome. Quote Link to comment Share on other sites More sharing options...
Tidgy Posted September 8, 2015 Share Posted September 8, 2015 to be fair it really depends on how hard you launch it and how many times, subaru gearbox's arn't mega strong, you chuck a 6 speed in, but they still fail if you start really giving it some stick. 1 Quote Link to comment Share on other sites More sharing options...
Darren1970 Posted September 8, 2015 Author Share Posted September 8, 2015 it would be good to know how much to rebuild thankyou. i will want to launch hard i know what im like on bikes so trying to find whats the best way to go, i was hoping to find out if there are any internal modifications that help. i was reading about strenghening plates that go on the gearbox to stop them bursting by the looks of it.

Scoobyghost Posted September 8, 2015 Share Posted September 8, 2015 Think the casing will be the last thing to worry about. Quote Link to comment Share on other sites More sharing options...
Gambit Posted September 8, 2015 Share Posted September 8, 2015 Place In Liverpool called gears will be the best people to ask they rebuild them and would know of any strong internals. Or even Andy forest might be able to give some advice but I know he's getting ready to do some races in Australia. So think he will be busy.
