hey guys,

what gearbox would you say would be best for a 450-500bhp classic road car?

5 speed with uprated internals

or

6 speed,do they do uprated gearkits for these?

i reckon 5 speed will be better for acceleration,but having all that power it may be better to use 6 gears to spread the power?

can anyone who runs either,give comments,experience and why that choice please.

thanks in advance

First off, forget POWER, it's NOT power that kills a gearbox, it's TORQUE.

That's why, when you go 2.5 from 2.0 litre, the increased torque kills the gearbox.

Mine is around 400/400 and I have a 6-speed non-DCCD box and love it.

ok well torque should be similar figures as bhp,i hope lol.

alcazar,so u have a 2.5 with a 6 speed?

having had both a wrx bug 5 speed and blob sti six speed ,would never swap six speed.took some getting used to.but six speed is the nuts.

Yes. Was advised that going 2.5 with mods made it necessary.

Several people on here said so, as did three respected tuners.

well the engine will be a 2.1, i was thinking about the albins gearkit or a similar one,but my mate said maybe a 6 speed would be better

Running PPG on our wagon with 490bhp and 2.1 stroker and this combination is amazing.

With a 2.1 running 450-500 you should be fine with either a 5 speed PPG or Clinic gear set tbh.

I have driven both albins and 6 speed.if I had the money it would have been albins.but I didint and bought a 6 speed.just going in now at the clinic

Albins are tested up to 580ftlb of torque I believe and have slightly longer ratios than the uk box. Kev runs one in his 22b @ the clinic. My personal view and understanding is that anything 2.1 or above on a 6 speed equals far to many gear changers on the road. So you lose the drivability, but then there's the uk hawkeye 6 speed with longer ratios lol
As Leeroy says its down to funds and of course personal choice. There both very strong boxes.
