    yeah you normally use the clutch setup to match the gearbox not the engine

    cool cool, i was just wondering incase the markings didnt line up:lol:

    i take it the 16V pressure plate is aloy stonger..

    because i was thinking of a diamond plate clutch, but didnt think the diaphtagm would be all that strong, especially if i didnt replace it... so is a 16v pressure plate more efficient?

    16v plate gives you a tighter grip, its not essential and if your going to buy and uprated clutch then i wouldnt bother.

    Still need a dizzy? it from an AGG, providing i can find it

    A lot of clutch kits use the same pressure plate, so I assume they've all upgraded to the 16v plate. A standard Sachs 8v clutch will be fine. Just make sure the surface of the flywheel is in good condition - give it a rub with some coarse sandpaper if it's gone shiny.

    Cheers

    This is what ive done so far towards my conversion...

    [​IMG]

    [​IMG]

    [​IMG]

    After 2 hours, i had my engine out...

    [​IMG]

    As you can see on 1 of the cylinders, there is a large amount of oil which has been burnt from th broken piston ring & Split valve guide..
    [​IMG]

    I moved the car out so i can start the engine build in the dry..
    [​IMG]

    I got my cylinder head back from having the valve stem seals, valve guides, valve seats & skim. (60 thou) i think..
    [​IMG]

    lovely new valve guides..

    This is as far as i have got so far[:d]

    a Kent GS2 is ideal for this conversion.

    yeah, i did think about the kent GS2H Cam, But i cant afford that at the moment with no income...:( i was looking at the newman 276 can which is 145 exc VAT .. that doesnt seem bad, but what do you reckon on the newman cam?
     
  15. Admin Guest


    probably much of a muchness about the two.

    I was really happy with the GS2 in my mk1. nice on idle all the way to the red line.

    2l bottom end and cam, i was making 140bhp:p

    i see you had one and sold it, fool:lol:

    Yeah had one, never fitted it.. sold it as i needed money! and was going to do a ABF conversion anyways:lol: :(

    i wouldnt mind a cam in it though! .. but at the moment, i need to concentrate on the fuelling side of it:lol:... im on a DMTL 32/34.. and want to try and rejet that for it if i can.. whether that means the good old drill bits if i cant find jets big enough:lol:... its just i cant afford twin carbs just yet:( .. you reckon the fuelling could be done on the DMTL?

    The DMTL will be fine, and theres more than enough jets around so you dont have to bodge/drill existing ones.

    The GS2H would be fine, as would a newman 276. Recent quality issues with newman have been a problem for some, tho others have had good results in the past.

    I'd also check the cc's in the head if you've had that much skimmed off, plus whatever it had off originally... you'll find the c.r fairly high.

    i think the head has been skimmed 2 times before.. but ill check!

    "mr hillclimber" check my 32/34 Jetting Thread, and give me some advice on what you think about my idea..

    plus, how would i know if i need to go up a size in jet? would it become slugish on the transitions from idle to primary main? etc etc

    cheers

    It maybe worth going up one size on the mains as a precaution before it hits the rollers, providing the current jetting is correct of course.

    one size on the mains?

    so from 120 to 125, which im guessing is a 1.25mm jet
    and on the secondary choke, 140 to 145?

    i thought that because the difference from the 1.6 to the 1.8 is a gap of 3 sizes, so wouldnt i need to go up 3 sizes again on the secondary choke to 155 (140 originally on the 1.8 and 125 on the 1.6) ?

    i thought this because the 1600 to 1800 is 200cc.. and 1800 to 2000 is also 200cc, so would add the same difference again..
