Which Gearbox.. The great debate..

SirDelton · 2006-09-30T06:21:38+00:00

The plan is to have a street driven Kitcar which is able to be used on the Race Track (NOT RACING) on club events. I want it to be fast & able to handle a Drag run or two without blowing any of the drive train apart. What I have is a EJ20TT & adapter plate to run a 2Lt Kombie box. But No Kombie box ATM.. After talking to people a lot of them have been saying the gear ratios in the Kombie boxes make the cars scream there heads off at 110Km/hr. This maybe great if I was looking for a Drag Car but that isn't what this car is being built for so now I'm thinking this may not be the best option. If I was to use a 2Lt Kombie box & the Tyre Dia of the 20inch rims I have been told will be anywhere from 630mm to 666mm depending on Tyre brand used. So based on this what kind of revs will this thing be pulling @ 110Km/h? What is the Max speed possible (If redline was possible) in top gear? (Sorry no idea what a Subaru Redline is.) What other option do I have for Gearboxes with better Ratio's? I don't want to spend $10000 Plus on a gearbox so please offer options way under that. (If there are any.) Thanks Darren Baker I'm hoping to do it right 1st time around even if it means I have to wait longer to drive this thing..

Hi, I have merged your thread into this one. I assume you have figured out you can buy albins gears in any ratios.

If you have a lot of HP and torque, you don't need 5 gears. Top fuellers only have 1 🙂

I have my gearbox set-up so 1-3rd is normal, and 4th is an overdrive. It's like a 5 speed with no 4th. It works fine cos I have excessive amounts of torque. In normal driving I take off in 2nd a lot anyway. So on surburban roads I only really use 2nd and 3rd.

Check the prices on boxes from the US, make sure you have correct shipping estimates and check the import duty. A mate got cheap BRM's from the UK, but had to pay heaps for import duty so they ended up being expensive.

And did you have your gearbox rebuilt locally whith your own gears or did you buy a prebuilt performance box?

Most of the info is in this thread. I used an albins 4th gear set, stock 1st-3rd. Rebuilt locally by Leons Motors. Links will be earlier in the thread.
