Get a decent sump made. Forget that trust 44 gallon drum junk.
I have a 9.5 litre sump and it's not the lowest point up the front of the car. Maybe contact rips in NZ and get him to make you one.
I'd rather spin the engine a little harder than constantly smack a hard cut, over and over again.
Can't help with your question, but seriously, don't bother.
Shhhhhhhh. The only thing the rb26 crank is good for is to put it out of its misery, crush it up and use it as road base! Never knew the magical sound waves of the RB 26 hoon the car down the road.A 400 kw GTR would benefit greatly by using a stroker crank. The typical "-5/400kw" type of build on a GTR needs more cubes than 2568 cc.
