You're unlikely to feel much benefit from a LSD in my opinion. The only time I find one would be useful is when pulling out of a junction with lots of lock on.

On a track I've never found traction an issue, with the back (either wheel) only breaking away at high lateral loads, at which point both wheels tend to go at once.

An example from today at ~95mph on a cheapy airfield day:

Quite possibly a feature of the camber sweep / pro-squat of the stock marlin geometry. I can launch mine like a hooligan in a straight line and it digs in and goes with very little wheelspin.

Unfortunately, the T series PG1 bell housing is different from the K series. So won't bolt straight to a K series. Though the 220 box will be stronger (has different bearings) and will be different gearing.

Your best bet, is get A PG1 from a 1.8 bubble Rover. If you get one from a BRM and possibly a VI, they will have a type B torsen diff in and bolt straight to a K series. BRM definitely had it.

Honda K20A2 from a UK Civic Type-R with a matching gearbox. Power unknown, but 197bhp stock, and mine has been remapped, so I'd hope it's making a typical remapped figure of circa 220bhp.

I'm guessing, running the R65 box, your running a 1.1/1.4 or 1.6 engine. Is upgrading to a 1.8 an option? Might be able to get engine/box/MGF gear linkage and ECU as a set etc. Straight forward conversion.

Ken Robson's car had a 1.8vvc from a BRM with torsen equiped gearbox. His car came to an end sadly, but he may still have the drivetrain.

Hi John.

Did think that but was unsure of circumstances with Ken's car. Would have it all for a conversion into another Marlin

Thumbs up Pg1 Lsd

Ken's issue wrecked the drive chain and the engine mounting holes, lugs and oils all scattered and its still an ongoing claim as far as I am aware, he was going to exchange the VVC, Dave Andrew's modified head (where the power was) but don't know its current position. His original doner was a BRM so would have had an LSD.

I had a VI doner and it was a std diff. I have a new PG1 with new LSD fitted ready to be fitted but it may not get there.

Might I ask, is it a Quife LSD? Just in case you don't get there, might be interested... Looking at building another hybrid box myself..

Brandon. Your 220 box. Is it a standard box with a standard diff? Or a turbo box? What do you see if you look through the drive shaft homes? A bar, penny washer looking or just a hole? If it has a torsen diff in it, could put it into a K Series PG1...

The spec of the car is 1600 k series piper cams and pullys twin 40 webers
r65 gear box
i have a complete 200 turbo car i think it has the original gear box it spins both wheels so i guess it has the torsion diff
i also have a vvc engine and gear box out of an mgf
i like the ratios in the r65 and is quite small and light
so i have a few options i guess i could fit the turbo engine and box but it looks very heavy compared to the k series any advice much apriciated thanks Brandon

Swings and roundabouts on what you what and how much work you want to do with the car. Going the 220 turbo route, you have a lot more to think about and work to do. Yes is heavier, but has a lot more torque and power as standard.

Can't remember how it works. But my 220 turbo donor, had a ordinary 220 box with a normal diff in it. Will find out for sure once you pop a drive shaft out.

Another common problem with the 220 turbo box (Type A diff), is the bearing carrier breaks. I did not realise in the Marlin until I had the box apart. As you can see here, no way of the driveshaft connecting to the diff!
