He advises against a bigger flowing higher pressure oil pump as what was suggested by Kaleb simply because he feels the turbo won't rob the oil pump of anything in any significant amount and the pump can only put out as much as the oil galleries allow for anyway. Seems logical. He did say that he'll be checking the oil pump and as long as it's still in pristine condition, he'll continue to use that one. The pistons are another matter. Now that they're definitely lighter, it means blueprinting/balancing the whole assembly ... from pistons to crank. No concrete word on whether we'll actually be using the Z32TT crank (the snout needs machining to fit the oil pump and besides, it was grazed by the air chisel used to get the rusted timing belt cog off). Nevertheless, it is definitely in the picture so hopefully something good will come of it. We've only discussed bottom end so far, so I'm not too sure what the story is with the top end (valves, lifters, etc). I'm sure if there was a major issue, we would've discussed it by now but maybe he also needs reminding when it's all ready to be slapped together again. I'm going to place an order with my dealership for the exhaust studs just to make sure that they'll handle the extra heat and more importantly, so I don't have to do any friggin' more motor work if I can avoid it!!!!! So that's it thus far guys. More updates in 1.5 weeks when I speak to him again.
Handed over pistons (and Z31T water pump) to my engine builder. He's keen to get the motor completed ASAP, which is good news because it means I won't have to kick his arse for being so damn slow with it!!
