It’ll be the same as shimming the standard oprv mate, so yes it has been done and I’ve done it myself. Small penny washers are all that’s required to do the job of shimming.
Shim the rear stub axles so you’ve either got parallel or slight toe in. It’ll help the turn in massively.
Some stuff called shim steel is your friend for this.
Well 80hrs ain’t that much on a road engine, but on a race engine it’s quite a lot mate.
There’s not much scope for increasing the oil pressure on the formula setup either as the oil pump is pretty s**t tbh.
Get a piece of 25mm silver steel (from memory the cam journals are that size) and put it in place of the exhaust cam. If it turns freely, the cam journals are worn and the head is essentially scrap. You can get the cam journals line bored, but I’ve only found one place in the UK that could do it...
Do you have vvt? Or is it not used on the formula engines?
The exhaust cam journals wear out and you lose oil pressure there. You can run an oil restrictor in the block to help improve oil pressure as well.
Update on this! My mate has been driving the clio like a hooligan with the blackline diff installed, and it’s all positive noises coming out of his mouth.
On track tomorrow. 👍🏻👍🏻
I’ve got a 129 (same as a 130, just has a speedo drive) that I can build up? It will be fully rebuilt and reliable.
Pm me if you’re interested @HarleyV123 👍🏻
You’ll probably find that the diff is worn internally - namely the planet gears have worn into the casing. It’s boot unusual to see tbh, but it means you’d need a new diff regardless.
I know the exact noise you’re describing and I can confirm the noise when up in the air is normal. As is the...
Mk2 crownwheel needs to be machined to suit the blackline - the same as the quaife. The mk3 crownwheel is bolted on. Couldn’t say if the diff fits in a Meg box though I’m afraid.
Did a trial run with the diff fitting this evening. Fitting was fine and no preload adjustment required!
Heated the crownwheel and fired it on the diff.
Only negative is the thread for the nut isn’t as nicely cut as you’d get on a quaife, but, the nut tightens down to torque spec, so all good!
For anyone else interested in the blackline diff, I now have a blackline diff in my possession to fit in a mates gearbox. It’s nigh on identical to the quaife, and I will be fitting it in the box tomorrow evening for a dry run - just to see what the fit is like.
If it’s all good, I’ll then fit...
Right ok fair enough. Well there’s a strong possibility that there’s an unhappy bearing in there then if you can hear a droning noise.
Unfortunately these cars were built in the knowledge that they were going to be abused.
But the diff will make noises when it’s jacked up.
They all make a noise when they’re jacked up, so I’d advise that you drop the oil out of it and make sure the oil has no debris/particles in it.
The gearbox code you have is a jc5 089. You ideally want another one of those, or a 129 - this gearbox has a speedo drive as does your 089. I can’t...
It’s alright you ignorant f**k. 😂

The bell housing of a 197/200 box is huge in comparison mate.
Only real option is to find a 6 speed TL4 from a dci as they have a smaller bell housing from memory, then fit the 197/200 gear kit inside the box.
Next problem to overcome is the crank sensor position as it’s different on the TL4...
