5 speed box into mk2 cortina is it hard to do

[jayv8 0]

hi iv got a mk2 1600gt running a 2000e box i want to go 5spd but wot iwant to find out is will i have to mod or cut the tunnel to fit it and wot prop will i need to get for it also is it hard to convert to cable clutch and cable throttle as im going to fit my 1760 xflow with 40 s

If its a Mk2 series 2 Cortina I'm guessing it originally had a single rail box? Then I'm also guessing the tunnels are slightly larger than the early Mk2's?. So there may not be much cutting if any required.

If its a Early Mk2 then yes you will need to cut the floor.

 

You will need another prop or the end of your existing prop changed. You'll also need to make up a gearbox x member to suit the T9 too.

 

Personally I'd stick with hyd clutch if poss, as cable clutches don't seem to last that long especially the aftermarket rubbish that seems to be floating around these days.

hi jayv8 if you look at 2nd of october i replied to this conversion that i have done

regards mikel.

Why would you want a 5 speed type 9?

The 5th gear will help to keep the revs down on the motorway, but fitting a 3.54 diff will also achieve that.

The 2000E gear ratios are much better spaced than the type 9 ratios...

That's very true but the lack of 5th gear is always going to be at the back of your mind, but a 2000e box with a long first gear with a 3.54 doesn't make for a car that accelerates that well, and still doesn't cruise comfortably!

 

There are other ratios available in the type 9 to give you a longer first gear than the sierra type 9's and they will still give cruising capability. You can also buy kits to convert a sierra type 9 to longer first gear for about £250.

 

Maybe fitting an RS2000 alloy bellhousing well get around the issue of having to bash the tunnel as I understand they are smaller than the cast iron type 9 ones?

 

You're still going to need to cut your tunnel for the repositioned gear lever hole UNLESS you buy a converted type 9 - this gives you the gear lever in the same place as the normal mk2 cortina gearbox tunnel gear lever hole. Basically the type 9 is "cut and shut" on the extension housing. Nothing major and something i wish i had done to my mk2 escort when i went from auto to type 9 as i wouldn't have needed to cut a thing then!

The bellhousing unless you're mounting the box right back about 8" or 9" isn't the problem in the tunnel. The main case is the issue being fractionally wider than the older 3 rail type boxes. Again this is only an issue for series one mk2 Cortina's.

Also you can only move the gearlever forward about 3" max on a type nine by shortening the tailhousing. you cannot move it anymore without a complete re-engineer of the reverse gearlever spring assembly. The only company I've seen do that is Voigts at £1500. In fact I'm not even sure if he is still doing them. And they still not really any better for Anglias or Cortinas as they still have the reverse spring housing behind the lever, thats the other bit that fouls on the tunnel.

 

 

Voigts Box in the flesh.

 

 

 

 

Here's one I did myself for my Anglia Van. The most you can get before hitting the reverse spring assembly. There are oil seals and bearing runner for the selector shaft beyond the join. There are a few MG companies offering the same as this for their cars now.

The box you modified is the type I should have fitted to my Escort - I only needed about 2-3 inches movement forwards. Nice job there.

 

Not heard from the original poster on your thoughts?

[kenbex522 34]

Cheers. I had to do this to get box to fit my Anglia without chopping huge chunks out of the floor. Another problem in an Anglia is the gear lever hiting the handbrake, so it solved that problem too. I'm not sure there is any benefit in doing that mod in a Cortina, as I'm not sure how close the handbrake lever is. In my current vehicle (Corsair) its dash mounted.

 

This pic shows unmodified T9 in my Corsair. Floor pan almost identical I'm told to an early Mk2 Cort, only a bit at the top of tunnel needs removing.

My concern with any car when fitting a gearbox is cutting out any of the cross bracings (which i had to remove part of in my escort) and it looks like I may have to remove one in my cortina either with the engine in it's normal position, or further back when used with a steering rack conversion. I've got an automatic car so the space isn't the problem width wise, it's when mounting the gearbox up to give good ground clearance.

 

I'm guessing looking at where your gearbox is sitting that the engine is further back due to a steering rack conversion, as the extension housing sits a fair bit behind the tunnel crossbrace?

[kenbex522 34]

Nope. The gearbox sits exactly where the end of the old one sat. As I've mentioned in one or two threads on here, I could just change the yoke and use the original prop. The only strengthener I cut thru is the one right where the bump is on the selector rail tube. But I've made a new bit to reweld in. The rack conversion has made no difference to engine position as thats a rear mounted rack and the sump bowl is in front of the x member.

in an escort the gear lever position with a type9 is the same as a mk2 rs2000/mexico anyway i know you have to chop the strengthening piece out and we used to cut the hole out offset so you can just turn it round and weld back in, you have to use a quickshift so that 2nd and 4th arnt either side of the handbrake. the box is longer so you need a shorter prop not just the bigger yoke i imagine that would be the same with a mk2 cortina.

No, a 1500/2000e (3 rail) box is 1/2" longer than a Type 9 believe it or not. The type 9 yoke is 1/2" longer in the body of the joint( not the long slidy bit). So takes up the difference, if of course you are putting everything exactly as it was.

 

This pic shows them side by side. I took the 2000e out of my Anglia and changed it for the type 9. The engine position stayed exactly the same. I just changed the yoke on the 105speed propshaft and it all matched perfectly. At the time I didn't realise the 2000e was longer either. Always thought the T9 was longer. Thats not to say about any other boxes, I've not tried those.

 

[creddersmk2 2]

well i'd never of thought that! the series 2 single rail must be the same length as well, i must be thinking like the mk2escort box with fixed bellhousing is shorter the mk2 cortina boxes were aswell. thanks for that :thumbup:
