611 Posted April 24, 2012 Share Posted April 24, 2012 Due to a bit of an engine upgrade i needed a bigger clutch to take the extra power. So after having a bit of a google and a look at the Over the winter jobs project that andyC is doing. i located a flywheel (A monza in told? can anyone confirm it is?) And i found a 9" clutch to fit on german ebay (see below) but what i want to try and find out is. This flywheel is flat and my previos flywheel was machined lower where the clutch plate goes and the clutch cover was flat on the face and the new one has the face set back a bit into the cover, so how do i tell if the depth is correct when fitting the clutch plate to the flywheel? any help would be great. The cover mounts fine to the flywheel as in the bolt holes all line up. I see on andyC's thread that it looks like he is using the same flywheel but i dont know what his clutch is? Any help or advice would be great. Andy. Quote Link to comment Share on other sites More sharing options...
andyc Posted April 25, 2012 Share Posted April 25, 2012 Looks just like the one i fitted to Johns car. All i'd say is get the surface skimmed as it looks a tad rough. Everything should just bolt up without any problems Cheers Andy Quote Link to comment Share on other sites More sharing options...
lamchop77 Posted April 25, 2012 Share Posted April 25, 2012 Std manta clutch will handle 160bhp but only just, any engine with more torque (2.2/2.4) will tear them to pieces in no time even the larger 2.2 clutch only lasted 10 miles max before it was knackered. You need a 6 bolt clutch setup just get the flywheel modded for a calibra turbo (same spline as 240 gearbox). This is from experience, my tuned 160 bhp grasser engine ran an LUK std manta clutch for 3 years and is still ok, the 175-180bhp 2.2 shredded a std LUK clutch in no time. i ended up with a manta 400 paddle clutch from helix.

611 Posted April 25, 2012 Author Share Posted April 25, 2012 (edited) Hi Andy Had planned to get the flywheel skimmed but wanted to check that the fit was right before i did so if i needed any thing else doing i coud have it done at the same time. Have you got the clutch fitted on your now? Shoud the amount the cover surface is recessed into the housing be the same amout as the clutch plate thickness or less? been a long time since i fiddle with clutches! when i put the clutch plate upagainst the flywheel and then the cover on there is a gap from the cover to the flywheel? should it be like this if so what should the gap be? i dont want to put it all in and find it wont disengage? Hey chris Thanks fo the info, im just looking at getting the car up and running and to see how much power i get and what the clutch is like before i spend a load of money on one as i still have loads of other stuff to spend money on! Its a 2.4 with 95.5mm pistons and a high lift cam from emen in sweeden, twin 45 throttle bodies with fully mapple ecu, so not sure what it will be putting out? i would think around 150-160bhp Just out of interest, what are your thoughts on what this is worth cost wise? The engine i was going to put into it, but am now going to sell (im just building it back up) is a 1.9 taken out to 95.5 with a 2.0l big valve head. inlet valves (45 i think) all ported and flowed, with a mild road cam. It was built a number of years ago and then sat in the garage for the last 6 years! it had new pistons shells etc when first built, i have had the bores honed, block and head cleaned, will re-seat the valves, head has had a very light skim and im just going to rebuild as is with all new gaskets etc.. would it be better to sell as complete but not run or try to sell head and bottom end seperate with gaskets to go with? Not sure what is best to do so any advice would be great. It ran great when it was all running and had about 130bhp but the cam is quite mild. thanks Andy Edited April 25, 2012 by 611 Quote Link to comment Share on other sites More sharing options...
lamchop77 Posted April 25, 2012 Share Posted April 25, 2012 Andy I remember the spec from our previous conversations, its only worth what someone will give you for it, and unfortunately lots of people just dont want to fit CIH motors. As for the clutch, dont jib on this bit!!!!! Its the weakest link in the drivetrain due to it being a 4 bolt type. Spend the money now and fit something decent like the calibra turbo one, any tuning after that will not be a problem. The recess on a 2.0 XE flywheel i have is 1.8mm and i think from memory that a 2.0 manta i measured was 2mm. Check your std manta one but i think 2mm is pretty much it.

611 Posted April 25, 2012 Author Share Posted April 25, 2012 Hey Chris The better clutch is on the list of later on bits! Doing these Manta's up seem to end up costing a small fortune! I have just finished putting all the running gear back in, the alloys are off to be refurbished, getting the engine re-bored and new pistons fitted and i still need to get the exhaust system made.. where does it end! I know what you mean about people not wanting the old CIH any more seems they all want those vauxhall ones. just not too sure if i should spend the time and money getting the old engine back as a complete engine or to try selling off the bits separate? I suppose by the time i have the head and block back together im not far off the complete engine any way! Thanks again for the info.
