Manual Gearbox Conversion BG9

[lowandy]

Ive been looking on trademe and the internet about manual conversions and 1 site i came across said that EJ gearbox will fit other EJ engines so they are all compatible. But not to sure so figured id ask on here.

I came across a manual gbox for sale with the code ty52vbaaa, will this fit my 2.5ltr non turbo bg9?

It says its from a wrx so would there be any difference to a non turbo gearbox apart from strength?

pull type clutch vs push on a NA

I bolted a WRX motor into my 250T/BG9 and ran it on the Auto just fine

make sure Diff ratios match would be the main issue

Cheers for that, i did hear something about cable clutch vs hydraulic? but i think its what you just said about pull vs push.

So would it be a safer bet to get a non turbo gearbox? Im looking to rwd convert it before i put it in so i thought id get a turbo gearbox to be stronger.

And if i brought a gearbox with matching diff combo, this would eliminate the ratio problem?

[Marky]

if its rwd it doesnt matter what the ratios are box vs diff anyway

[lowandy]

Ok so it seems that there are only turbo manual conversion available to buy, does it matter about the push vs pull and how would i get around this?

Bump. Still looking for this. Would i run a non turbo flywheel or turbo flywheel if i get a turbo gearbox?

I am about to do the same with my BH9 conversion, Just get turbo gearbox complete with clutch and thrust bearing, The pull type clutches are stronger so will last longer with a non turbo. Just confirm that you have matching ratios. 4 bolt/8 bolt bellhousings all interchangeable, you just use less bolts if you put an 8 bolt on a 4 bolt block.

You would need turbo flywheel, just treat it as if it was a turbo car and use all turbo bits, Easier to locate second hand anyway

Pull vs push, Turbo gearboxes use a thrust bearing that clamps into the pressure plate and pulls the pressure plate away from the clutch plate, push (non turbo type) pushes the thrust bearing into the pressure plate to release the clamping force.

If you are running RWD then any gearbox will do, ratios only matter if you are running AWD.

I assume the car is auto at the moment? a manual hydraulic clutch assembly from any legacy/wrx 1989 - 1998 will fit.
