slabbyfaceddean Posted September 3, 2019 Posted September 3, 2019 (edited) Took the head of my engine today to find it had been rebored to 1216 . I was told it was a standard 1127. Dont worry about the blackness on the pistons, carbs needed a good set up ,clean and jetting properly. They cleaned up rather good with a wipe of petrol. My Question is does anyone know what the pistons are ? They have B00H4 markings on them. Anyone know ? Edited September 3, 2019 by slabbyfaceddean Quote
vizman Posted September 3, 2019 Posted September 3, 2019 They look like Wiseco, no good for turbo. Quote
Dezza Posted September 3, 2019 Posted September 3, 2019 Keep delving. You may be really lucky and find it's got Carillo rods too! Quote

I used 1186 12:1 Wisecos in my first turbo - barrel spacer knocked the CR down. There is also a fair amount of crown thickness that could come off with would reduce the spacer thickness and achieve a better squish! Quote
slabbyfaceddean Posted September 4, 2019 Author Posted September 4, 2019 No I pre bought Busa pistons before the strip down as I thought it was a standard 1127, so once these are identified I'll stick them up for sale. Quote
vizman Posted September 4, 2019 Posted September 4, 2019 Ok, not the best option for turbo use..... ......but if you’re not using them it don’t matter. 1 Quote
clivegto Posted September 4, 2019 Posted September 4, 2019 (edited) They are wisco. These are some pics of JE high comp & low comp pistons. Interestingly they have the same numbers cast into the inside. So presumably the turbo ones have been machined down. Edited September 4, 2019 by clivegto Quote
slabbyfaceddean Posted September 4, 2019 Author Posted September 4, 2019 I just need to know the CR off them I suppose. Then I'll stick them up for sale anyone recognise the code ? Quote

slabbyfaceddean Posted September 4, 2019 Author Posted September 4, 2019 (edited) Block/ Barrels and pistons are off now.. Edited September 4, 2019 by slabbyfaceddean Quote

Put a piston back in there with highest part flush with top of barrels, measure how far piston is down the bore.Stick a piece of perspex with a small hole drilled in on top with grease round the edges. Get a syringe with oil in fill it up then deduct the amount of oil from size of top of piston if it were flat. Edited September 4, 2019 by clivegto Quote
slabbyfaceddean Posted September 4, 2019 Author Posted September 4, 2019 Been on to wiseco , they are 12-1 CR. Quote
