j7r

Hi guys, I need to rebuild the R21 turbo engine in our HoverAid hovercraft and the head bolts we ordered turned out to be the wrong ones. Does anyone have a set we can buy and get hold of in the next 48 hours? We have a fundraising event on Saturday... Help! Cheers Andy Mayo

Hi. I'm trying to understand correct cylinder head bolt tightening torque for J7R 752 R21 Turbo 1988. Dialogys shows 87.5-97.5 Nm for all engines. Instruction for cylinder head gasket - pre-tightening 20 Nm, than 120°+120°+20°. Where is the truth?

I Am under the belief that the crank fitted to the 21T is in some way stronger/different to the N/A versions of the J7R. I Need to know what the difference is, if any....can anyone enlighten?
