Haven't updated this for ages. We sort of blew the car up at the end of last year. Or thought we had, but turns out it was just hydro-locked with oil. During some very enthusiastic laps of the speedway track, the breather filled up the intake manifold with oil. It lost power and had massive amounts of smoke and oil was pouring out of the exhaust and air filter. Looked bad, so we packed up, went home and tore the engine down.
Inside we found it was running a blacktop crank and piston set, with new flycuts made to clear the 16v valves. This was in a 7 rib block without oil squirters - either from an mr2, or from the very last of the jdm ae86s, which is what the engine came out of. So that was a nice bonus. Rebuilt with new bearings, rings, a ported head and ~264 deg cams, it now has around 210psi of compression instead of the normal 180 and sounds absolutely furious again.
Pic of the pistons and a standard bigport piston for comparison.
And here's the motor looking all pretty before getting covered in dirt again
Also put in a half cage and harness because things were getting pretty crazy by the end of last year
And now we're back to doing this again!
