I think accepted wisdom is that p30 block can be safely taken to 86.
n42/f54 blocks preferred for bigger bores.
unless you're prepared to fit liners of course.
I have rods from Maxspeeding rods in my current and previous engine. I have very close tolerances between piston and head and no contact and no problems at all. I'd recommend them.
I think a short stroke engine is cool, but even the LD crankshaft isn't super long stroke and will rev.
I'm revving mine to 7700, and my previous engine with l28 crank went well past 8. (in the end it was valve train that limited the rpm)
Thanks. I like the weather TBH. Brexit is... hard to explain
This pic is of the piston in situ - you can see where the proximity of the head squish area has kept the piston clean. This is my previous engine with 0.6mm head to piston clearance.
I've got 11.8:1 on normal fuel, but I believe our fuel is better in UK than yours. I run it on 99 ron, although I didn't hear any pinging on 95 either.
0.8mm clearance and lots of squish.
you've either been incredibly unlucky or its not the diff.
anything unusual about the suspension or gearbox setup?
whats the noise like coasting out of gear? in gear with the clutch in?
