[Darren1970]

Hi Guys

new here, i have a 94 classic sti, the dive train feels rough and needs sorting, im wanting to do some drag racing, what upgrades are worth doing for aggressive launches?

few spare gearbox's will help ;) lol

As said above [emoji3]

But will need a good strong box and matching diffs.

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.

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

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.

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.

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.

Think the casing will be the last thing to worry about.

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.
