Thanks, Stefan

From memory the standard Mk2 8v GTI vented rotors are 239x20mm

I reckon the min. th would be no less than 18mm.

Hey,

Ok i went ahead and got myself the 276/268 cam, havent fitted it, wanted to do that on the long weekend... Now im looking at getting some parts from gap, the driveshaft to gbox seals as they are leaking.. Im thinkning of getting a adjustable cam sprocket too, do you guys think its really worth it? would give me the chance to play with the powerband of the cam alot easier wouldnt it? I also think the cam sprocket bolt is a stretch bolt, you guys just reuse that one or get a new one?

Thanks, Stefan

nice work stefan!

did you get the cam from techtonics tuning? because if you wanted an adjustable cam gear/sprocket, they do cheap ones too. ( inexpensive cheap )

realistically, people who i've known with adjustable cam gears just set it at a certain point and never touch it again. if you plan on playing with the power band or seriously shaving the head/decking the block then cam gear is +++

Thanks Jay Nah got it off a mate who sold it to me cheap. Im just thinkning of leaving the engine stock for now... is the cam gear really worth it or should i wait till i do more mods and run it with the stock one for now?

[jayjay]

if you plan on leaving the engine stock for a bit, just chill with the stock cam gear.

Yeah thats what i thought too. Thanks for the help mate Will update this when ive fitted the cam and see how she goes now!

Hi guys,

Ok so i tried putting in the new cam, all went well until i wanted to start it... Wouldnt go, found that my timing was out by 3 teeth., I adjusted top and bottom end timing and its all spot on now. Tried to start but all its doing is crankning over fast and popping out exhaust. This sounds like ignition timing doesnt it? My rotor arm is on ht lead 1 and my firing order is 1, 3, 4, 2.. Is at all just a matter of adjusting the timing by turning the dizzy or am i missing something? Its digi 2 btw! Any help would be awesome!
