Also from memory Ridgecrest don't make a copper gasket for 18rg (if this is wrong or someone else does let me know). 11/12:1 is high for 98Ron, where were you getting pistons like this as I'm also trying to source some (though only around 9.5:1) JP's in Adelaide haven't made 18rg pistons previously and require specs which I'm also trying to get (anyone, anyone). A metgal gasket would let you "play" with comp ratios if the pistons you want aren't available. The rods should be studded, studding the crank isn't a bad idea for higher revs. Bore stroke for 18rg is 88.5 x 80 (though another source says 89x80, confirmation) and so is over square, good for revving. Good cams, the right head (88253 has larger valves) balanced and well built shoud be strong enough and have adequate power for N/a motor. [Report message to a moderator]
