piekey Posted January 6, 2021 Report Posted January 6, 2021 Wow thats news to me, i wonder if they sell many ? The more gears means more gear changes. I don,t think 6 gears would be of benefit in a road car. Type 9 5 speed close ratio all the way for me. Spend the ££ saved on other upgrades.

Ouch, seven and a half big ones for one of those!
deltamal Posted January 9, 2021 Author Report Posted January 9, 2021 It's lots of pennies, so I'm fimishing my Mk5 crusader estate off instead, long term project! the block has been re bored, decked,crank ground and fitted wih a stage 2 head that I acuired but turns out that it was not all it could be, issues with the cam (injection), valves (standard), gas flowing (not finished) and porting that didn't match the manifold but it's being sorted now with a suitable high torque cam with the head relieved so that the oil seals dont get crushed, bigger stainless valves, correctly flowed and ported, and then the ECU re mapped on the rolling road, so should then be nicely drivable! the rear valance needs replacing and then it's ready to go! 1
