Saw it at the Spit yesterday, so it must be driveable to a degree?

Well that's what I thought. I saw him about 3-4 times on the weekend and James and I had different views on if it was fixed or not. From this thread, I gathered it was still waiting to be fixed because he said he didn't want to spend the $4000 to rebuild it but buy a second hand engine.

Oh wells.

um - might take more than 4 days to build an engine guys

Car still not fixed no, should get the replacement engine put in later this week, yeah you guys did see me the car is still drivable as long as i dont use too much boost. Its just one piston doesnt have much compression, but as if i am getting a new engine its doesnt matter so much if i drive it around still.

I didnt see you guys shane and nismogirl, i saw james car at the spit though.

hopefully my car is all sorted for the msciii cruise.

That's what I thought. I kept telling James that I didn't think it was fixed!

We were parked beside James car. Yellow VL. Andrew's car.

Just be careful that you don't screw your turbo due to all the little metal bits from your piston ring lands floating around in your oil...

Speaking from experience here

same thing happened to me dude, Although i got greedy and stupid and wound it up to 16psi for 2 weeks, went good on the street at night but at the drags it shit itself and i too had a lumpy arse skyline, Got home, removed plugs, had 30psi in number 5 cyl. Pulled engine out, removed head and seen the exhaust side of number 5 piston was melted. On 12psi it shouldnt have done the damage it has. Would have to be a mixture of things, poor fuel, blocked or restricted fuel filter or injector, too hotter spark plug, timing to advanced, engine temp higher due to faulty t/stat or loss of water, surely something else caused it, i ran around on 13psi with stock cooler and everything for along time before i upped the boost and too be honest, the car actually went better on 13psi than it did on any other boost level with stock gear. WHY did i crank it up?? Inexperience i guess was the main thing, i just wanted to go faster and i didnt think of the consequences, But anyway what i was getting at was i had to rebuild my engine also. The bottom end of my engine is done. My piston Kit included ROSS pistons, rings and gudgeon pin. 1600 was the price. AS for the Rb26 piston i dont think the pistons are the same, im using the Rb26 crank and rods and i think with the extra stroke of the crank the gudgeon pin has to be set higher in the piston whereas the rb25 gudgeon is lower, Dont quote me but this is what i think is the case. Good luck with it anyway.
