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.

which engine gearbox and tyres are you useing it looks like it goes quite well

Don't know of a LSD for the R65 box. Pg1's had the torsen diff

ive got a 220 tomcat so maybe put the box out of that in ?
would it fit a k series engine

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.
