Thanks for your advice ppl. The block has already been bored out to take 88.5mm pistons, so if one can use 18rg pistons with the 2t crank then I'll give that a go in 1.8L form
I agree it would be EASIER and SMARTER to use a 3t bottom end to displace 1800cc, but I want it to rev like a demon not tow caravans.
" Can you hack camming up then revving out the motor to 8000+ RPM every day to make it perform? "
You make it sound like a bad thing....
Supposing it turns out bad, has anyone got a spare set of (cheap!) 89mm 3t pistons?
