Advice on gearbox

[littleblue1]

Looking to be running around 240 bhp on my vtr been told that a standard vtr box wont take the power, is this true, if so what would you recommend running, btw road car not track, bit stuck on what to go for

[axsaxoman]

that depends on a few things
1 is the gearbox good now?--eg has it been rebuilt recently--If not drain oil if its grey in colour -then time for a rebuild
2 how mechanically sympathetic are you
3 turbo or s/c
4 lsd
5 how much torque and rpm it is at
6 be box is not that much stronger anyway--and can be broken just as quickly with bad driver
7 is power figure at fly or wheels
8 type of clutch
9 you going drag racing
10 impressing people by wheel spinning it

[littleblue1]

No gearbox has not had a rebuild, not one of these types of guys who wheel spins to impress lool that's a kid in a 1.1 fiesta looool! Turbo and hopefully 240 ATW, I would like to think I'm a good driver

[MartinObviously]

Gearbox would take that I think, if it's rebuilt.

I'd be fitting an LSD with that kind of power though, otherwise your passenger side tyre wont last long :P

[littleblue1]

Yea I've been trying to get hold of an LSD box but can't find 1 anywhere

Threads just been posted in the forsale section. Vtr box with quaife diff if thats what an lsd is?

Quaife make LSD (limited slip diff) differentials.

So I'd say yes.

Ask the person selling it just to double check :p

I wouldnt worry about fresh build unless the synchros are new tbh replacing the bearings wont matter a great deal all the ones ive seen knakerd have teeth missing.

Also its not so much about bhp more torque like said above. Answer all of the questions gmc asked and you will be in the right ballparc of making a sensible decision.

A cars only as good as its shittest component.

With sympathy the MA box will survive with a diff - I'd advise a quaife (gmc have/had them on offer). Drive it with any aggression though and you'll shit the MA. The BE (as John alluded to) is stronger but it's not invincible. I'm on my 3rd now.

[littleblue1]

Yea I've been talking to the guy selling the engine and box he won't split ha to come as a complete package, I've been looking I to getting the be conversion but I am more than likely going to rebuild my box or buy a recon box tbh and keep that stocked up lool! Mr sure on torque hoping for roughly the same figure as bhp if possible, and not surprised Ross ur running over 400 bhp lool

[Tom5190]

From experience i saw one go out with 280hp (not sure on the torque) and come back the very next morning with stripped teeth in on the standard diff.

Few weeks later it went out with gripper inards..... again it came back the next day with stripped teeth on the crown ha.

[littleblue1]

So it all really depends on how you treat the car then to be fair haha
