    This has just reminded me of when Pete Rosenberg said he would put an SR20 clutch into my CA18DET'd S13 and someone who surprisingly didn't invent the conversion saying fook off it can't be done

    All I can remember was it had a modified S14 flywheel with S14 flywheel bolts the starter motors still up the shed somewhere but I didnt think to check what type it was to be honest.

    The guy I bought it off was running big power with an S14 clutch aswell.

    When I bought my last CA and all associated bits it was fitted with the S14 clutch setup, the previous owner was running around 450 BHP.

    I changed it back to an S13 setup though, I ran this ckutch http://www.apexperformance.co.uk/cat...f677fb43f4bfa4

    Why not just order your SR20 aluminium flywheel with a CA ring gear on it?

    Spec make aluminium flywheels for the CA and the SR so they could probably do it for you.

    I think I might try to replace starter ring on SR flywheel with the ring taken off CA fly, any reasons for this not to work?

    I have couple of questions about SR20 fly+CA18ET starter combo... First, minor, is that starter hits block ventilation tube a bit, did those who made this conversion had this problem?
    And second, starter teeth step is around 11mm, while SR20 flywheel teeth step is 8mm (the same as CA18 flywheel). Isn't it too much of a difference?

    ummm.... why go thru the hassle of SR hardware, if CA18 bits will suffice ?
    this thread... about 10 posts down

    looks like a pretty intense setup to me. Note this item; 14. Custom clutch house clutch

    that link I posted with the low 10sec full street red corolla doing wheelstand launches.... that is the very outfit, he told me did his clutch.
    Perhaps contacting that nico member would shed some light

    That would be one-off clutch, so probably expensive, and surely harder to get than more common SR20 clutches, I think

    I finally got my hands to test-fit SR20 flywheel with CA18ET starter. Well, bad news is this starter doesn't fit this flywheel too good - it makes bad sounds when cranking, and flywheel teeth were damaged a bit after I cranked it for a few seconds... Did anyone else have this??

    More holding force due to larger diameter and longer "leverage"... Also cheaper and plentiful flywheels and clutches
