Gearbox choices


Recommended Posts

Posted

I seem to have a thing for gearboxes at the moment, there seems to be a lot of good sensible knowledge here so whilst what I might have planned may be frowned upon I'm hoping someone can help gearbox wise.

I have a supercharged 2 litre EFi Pinto (205 block) waiting for me to do something with, I did have a type 9 box but when I was skint I sold it. It actually turned out to be goosed so I refunded the lad.

So I don't have a gearbox for it and I want a replacement and Type 9s seem very expensive now.

Are there any other alternatives? I know you can use the MT75 unit with an adapter which when I swap out the Pug 2.5td on my van I can use the MT75 mated to it as it'll be replaced for a Merc diesel.

It'll all end up in a Reliant Robin eventually but I want to keep an eye out for a suitable box.

Mazda box? Rx8 boxes fit with an adaptor. Downsides being the gearing is too low on first on a regular engine and if your knocking out masses of torque it might struggle.

Posted

Wow they're cheap but looks like length could be an issue as it looks a good bit longer than the type 9. But then I could move everything back and it might help balance it out better.

So the box is around £150 and the conversion kit about the same.

Would the RX8 not be putting out more torque than a Pinto?

Rx8 and torque don't belong in the same sentence.

 

The Mazda box has been used in mk2 escorts and I know of a bloke who won't use them again after blowing two.

Yeah googling them they all mention the same thing. 

I think I'll run the MT75, apparently it can be done without the adapter and using a spacer for the clutch release bearing.

Mustang and TVR boxes should bolt up *I think* but you won't be saving any money that way. Pretty sure they're the same or similar to the MT75 with different gears, but it's been way too long since I looked into it so don't rely on any of that...

I think the only issue with the MT75 might be that the ratio is a little short and Ideally I want to have a bit of fun and get a decent 1/4 mile time with it.

What axle are you using? Maybe easier to get a mt75 in there and change the diff ratio to suit the box/powerband.

The 230bhp rx8 which the 6 speed comes from has roughly 155 lb-ft of torque, a standard injected pinto has about 120 lb-ft of torque that's before your supercharger and any other mods,

 

I'd say for ease grab another type 9 one will take a supercharged pinto's power and torque

 

You seen this type 9 listed wrong on ebay, £125 b.i.n

T5 will fit and should be a straight bolt in but that is the sierra cosworth set up so not cheap.  

 

Given all that don't discount the MX-5 boxes, unlike the Ford ones there are plenty available.   I think that kit cars and Morgan have moved to using them with a longitudinal duratec so they must be reasonably strong.

Sounds interesting,

Sounds mental,

Sounds lethal!

Would a Borg Warner t5 fit? That said one of those would be expensive

Probably but it's only being done for shiggles, it'll be fully caged etc but I want to make the exterior look as original as possible which I think I can manage. 

Axle wise I'm not sure I might just see how the Reliant one does and then when it eventually explodes I'll probably change it out for a shortened Ford or perhaps Volvo.

I was going to try and use a Trabant but I can't believe how expensive they are.

Posted

I think I'll see how my MT75 works out but in the meantime stash some monies away and keep an eye out for a Type 9.

Are RWD Volvo gearboxes viable? There's one on here for £100, with a free car included.

Ive got a few type 9 boxes at my yard and also a couple of 4 speeds. Im only at Durham so local to you. If you still have the knackered type 9 I have a contact who gives £50 for them. Let me know if any good.

I weighed it in unfortunately it was just as I was moving so I binned it to get rid.

How much do you sell them for?

 Prices are pretty much dictated by what banger/ stock car lads pay. Normal type 9s are £150, Type 9 with long second gear (out of P100) are £250. 2 litre 4 speeds are £100 and 1.6 4 speeds are £50. All are complete with gearstick and clutch fork.

.... so a 'crock/rusted to the drive' FoMoCo is not worth owt* "scraps on its arse m8, I'll drop by tomozz @ £50" is a big earner, then?

Do the 1.6 4 speeds sell at that? I couldn't give a low mileage one away it had a gearbox mount and prop with it as well

Gearbox will be worth a bit. Depends if its a 1.8td or a 2.3. If its a 2.3 check the vin plate for rear axle code If its code m its a 3.14 diff which is worth £££££££££s to the kit car boys
