Will A 1.8Td Gearbox Fit A Xu10 Turbo 8V?

Recommended Posts

Slo

Im running a 2.0 8v turbo and I want to get rid of the silly 1.6 be1 as the ranges are far too short for it. Will a 1.8td box fit my 8v turbo xu10j2te? or do i need the 1.9td box?

Whats the difference?

Also whats the chances of converting the be3 box to be1, would it be easier to convert to the be3 controls?

 

Cheers

The beauty of the xu and be gear means that any box with the correct bellhousing bolt pattern, i.e. be xu, will bolt on.

 

What you need to do is make sure the diff is a 205 diff (the later diff from a xsara or 306 or 406 etc... Will be bigger and your shafts wont fit on the passenger side). You can get around that by either chopping the end off of your shaft, using a 306 inner cv, or by swapped the diff for a 205 item.

 

You also need to make sure the top selector arm is a 205 item, not a 306/406/xsara etc... The 205 item is a flat arm with a ball on the end, a non 205 item is a funky bent arm, a bit like an 's'. You can generally swap the 2 arms without issue.

 

Generally a be1 box is easier to convert to a be3 assembly, but not all boxes have the right casting to do so, but fitting the be3 set up is 10x easier and a better idea imho. The be1 clutch setup is a nasty system designed to fail. To go be3 you'd need a new release bearing (£15), clutch cable (£15), and to modify your pedal (turn it in to a hook where the cable fixes) or buy a 2nd hand be3 (£15). I assume your be3 box has the clutch arm and shaft, its generally good practice to fit new bushes (check if they are white or yellow).

Thanks for that, its coming from a 205 and thinking about it I might as well take the whole gear selector mechanism, linkages and pedal box to save messing about while they are available. Great to hear the box will fit on the lump. Will my 1.6 gti shafts fit it too?

I wouldn't want to try using 1.6 shafts with a turbo, even though they do fit.

 

you don't need any of the selector mechanism, that's all the same, all you need to run a BE3 in a pre 89 car is a post 90 205 clutch pedal (all the same) and a post 90 BE clutch cable.

The shafts have been in it since the conversion infact they're the original shafts and have been spot on so far and its had some stick. Was a little worried about them snapping but been sound so far.

 

What about the lift up reverse thing? Will it just work the same with reverse behind 5th and just disregard the lift up cable?

yep, just disregard the cable.

Yeah, dont fit the cable at all, it will cause problems selecting gears, just leave the breather there (where the cable would normally screw in).

 

Nothing wrong with 1.6 shafts, just they wont take the abuse like a 1.9 shaft with bugger cvs. That being said if you have 1.6 hubs you'll end up needing to swap those for 1.9 hubs in order to run the 1.9 shaft due to spline count.

Have you put the 1.8t box ratios into a final drive/ tyre size calculator? You can find all the info online and will tell you max speed and rpm at most speeds in each gear.

 

Don't chuck the Be1 cable and collar setup! Hard to come by and will be worth £30ish.

Wont be chucking any 205 parts anytime soon. I have no idea what the ratios are, I dont even have a box yet going for it tomorrow. Im just sick of jitser revs, tazmanian devil acceleration and landrover top end. Not to mention a fuel guage that goes down quicker than a 16 year old in a corsa.

If it's all coming out of a 205 don't forget the little things like the be3 gear knob (or just the map) and the sleeve from the be3 car's gearstick to replace your lift up mech. And the be3 does use a different thrust bearing to the be1

What tyre size are you using and what is the turbo engines rev limit?

 

I'll find the ratios and post the rpm in each gear.

I don't know the ratios of the 1.8td by heart, but do recall that it was pretty long.

I use the 1.9td box from 306/xsara and find it a pretty good match for the engine. Except the first gear, which is short. But I think that is common for diesel gearboxes.

A turbo car I finished for someone had a 306 TD box in. Ok yes the long ratios are more suited and allow relaxed cruising. But the gap between 2nd and 3rd just totally killed it for me. Even on the car in question with 250bhp and similar ftlb. I drive a turbo 205 for fun so it's the GTI close ratios for me all the way. If I want to cruise at low revs I'll use my BMW.

Fair point, but bit dependant on the engine. Mine has 220bhp and full boost at 2800rpm, so does pick up easily in 3th. For a car with turbo gap, I would pick a shorter box.

Ok i've got the box and it came with the thrust bearing but not the gearstick sleeve, just the bare metal mechanism. Ive already got a be3 knob in my car that ive been using to save my new be1 from use.

 

If any of these gears are too high for my engine whats the chances of swapping the lower equivalent from my original box into it? Ive got no idea what power its putting out but its a bit of an animal.

Tyre size is 195/55/15 and its running oem management so its what 6000 revs?
