    Just plain wrong!

    https://rover.ebay.com/rover/0/0/0?mpre=https%3A%2F%2Fwww.ebay.co.uk%2Fulk%2Fitm%2F312929698581 talk me through this one!
  2. The rear crankshaft bearing carrier is a source of oil leaks often confused with a leaking oil seal as I found out to my cost. When fitting the rear bearing carrier use some sealant before pushing the bearing carrier in place, you may see a little seal and pushed out of the gaps, wipe the excess of the inside of the engine, also use some sealant before pushing the fibre wedges in when fitting the sump gasket.
  3. I’ve got smaller plugs and adaptors in 1 of my Pinto’s, got the plugs from Burtons, they look just like normal plugs with a thinner threaded bit. the adaptors sit flush to the chamber walls, the plugs a little higher than standard plugs, top of plug where the lead sits is exactly the same as standard plugs. i assume these plugs are just a different size of car plug. bike plugs used to have a different lead fitting (screw or clip) which may be where the “leads won’t fit” statement but most are the same as cars now. when I’m building an engine I do a chamber volume measurement using a pippet but think the statement that fitting bike plugs and adaptors will increase compression enough to make 2 bhp is pure fantasy. I also factor in 1cc for ring depth below piston top however you can change your compression value by using pie to more decimal places and then making excel display less decimal places in the final solution.
  4. I’ve done a quick and dirty calculation on compression ratio for you engine. now there are some assumptions because I don’t know your piston deck height and I don’t know you actual chamber volume, that said it won’t be far off...ish i use Rheinz when I can and they have a 1.3mm thickness compared with 1.63 standard. so with all that said my calc put your compression at 10.65 to 1 at most ok if you make sure you ignition timing is ok
  5. Thanks for the info im getting carbs refurbished and fitted to a manifold that will give a bit more access then I’ll go to one of them.
  6. I took a look at your profile as I’m suffering with bike carb problems to but Wales is a bit far to go for a RoRo tune. The original spaced and horizontal set are massively overfueling and other sets are just not right, my thoughts are to either get one set refurbished then tuned or sell the lot on eBay and start again with a new DanST setup and get it tuned in His place in Bingley or at Northampton Motorsport. ive even got a set of bike throttle bodies on a Pinto manifold but need a new fuel tank, fuel lines with return, fuel pumps and ecu to make it work....Aaaaarh
  7. Car Builder Solutions do a selection of servo’s and I note they do a twin servo setup, it’s a beast and probably needs fitting in the boot.
  8. I run V6 Type 9’s in my kit cars using a spacer between bellhousing and box 1 Kit car runs a 3.9 diff and 195 60 14 tyres yes the 3.3 1st is still low but engine goes to 7500 so I can sort of mask the gap
  9. It’s all about the price Type 9 price for secondhand is heading north of £250 and that’s with nothing more than a visual check by taking the lid off. i have seen recon boxes on eBay for £750+ again no way of checking quality except eBay rating. BGH Geartech is well renowned, been in the business forever and will build to any spec or ratio’s Take a deep breath when you look at prices.
  10. Tins of Slimfast and you’ll save 5Kg for little money and feel better at the same time. weight saving on a heavy car needs to be everywhere not just 1 bit, alloy hubs, alloy engine etc. etc. etc.
  11. On my Lotus 7 replica the 4 Branch manifokd wraps round the drivers footwell. I glued glass heatmat to the outside of the engine bay bulkhead and inside the footwell . for your application andbif you have space a simple ally sheet heat shield with an air gap between the exhaust pipe and pipe tunnel will help reflect heat, glueing silvered heat mat to the tunnel helps with transmitted heat and another layer of heat mat under the carpet should reduce conducted heat. its never one solution
  12. V6 Type 9 is stronger and has better ratios longer 1st 2nd and 3rd standard 1:1 4th and slightly longer 5th just need a 30mm spacer and an in-line bellhousing
  13. R,L or P stamped on the head back end on the exhaust manifold face 2.0L 48cc combustion chamber 1.6L 38cc combustion chamber putting a 1.6 Head on a 2.0L block makes the combustion ratio far to high and a skimmed 2.0L injection head is a much better base to work with
