So it seems my mechanic said he thought it sounded like the upper bottom end and it seems he was right. No compression at all in 1 and very little in 5. No visible holes or cracks in the block, sump etc. It also blew the blow off valve off. He doesn't think there's much point in pulling the head off yet. Will do that once it's out of the car to fit to the new block.

His opinion is it massively over boosted and damaged pistons when it backfired.

So the Phoon bottom end is on order and I'm looking into valve springs and a billet oil pump gear. Any opinions of good gear to look for?

I hate to say it, but it seems like atomic can make good parts, but can't put em together properly! Nizpro do oil pump gears too don't they?

Yeah this seems to be the case. There's a few bad stories going around about their engin builds.

I know there's a mob over here in WA that has a pretty good reputation for there oil pump gears... Kostecki race engines I think they're called. Might be worth a look into :stirthepot:

Cheers mate, will look them up s well as Nizpro.

Upgrade your actuator and port your waste gate port out while the motor is out.

But this would require a tune. I will be doing a couple of mods that dont require a retune (oil pump gears, valve springs, intercooler, piping(?)) but I want do all of the mods that require a retune at once after its run in good and proper.
