Hi there, Hoping someone can advise which gearbox would be worth using from the selection I have available, or if I should be considering others? I'm intending to do an 02A conversion to my Scirocco mk2, using an ABF engine on 276 duration cams and Jenvey / lumenition ITB's and management. I have the engine and quite a lot of donor parts available including several gearboxes at hand. The engine is quite heavily modified and should be putting out decent power. I have a CHA gearbox available that came from a Passat TDi, a CDA box from a mk3 GTi 16v and also I think a DPA box from a later mk3 GTi 16v. The box is going to be fitted with an LSD before installation in car, and I've the option of swapping different gears out with assitance from a mate who knows a bit more than I do about such things. I've had a look through the forums and there seems to be little information on the CHA box, if I understand the ratios correctly, it looks like the CDA would have quite short ratios and a relatively longer 5th gear (motorway gear)? I don't want to compromise the acceleration and performance with anything stupid, and my knowledge is limited in this area. Wheels / Tyres will be 195 45 15. These would be used with a lightenend flywheel (6.5Kg iirc) and new uprated VR6 clutch. Thanks in advance!
