What the bollocks were you thinking letting your mate BOUNCE OFF THE LIMITER, UNTUNED on 20PSI???????

U shouldn't even drive on boost AT ALL untuned let alone on 20psi!

Personally, I think 5w oil is too thin. As soon as it heats up its goin to get thinner than 5w. The oil will heat up quick especially if your tappin the limiter. Nissan probably recommends 5w for a stock vehicle in Japan, but over here the weather is hotter and there is not a whole lot of us running stock engines. I run 20w mineral synthetic blend and a few mates with tougher engines run 15w and 20w. They have 400hp v8s, a couple RB's and a SR pushing out 300kw at the wheels. The only engine failure I have seen from them is a rod through the block on a mates 383 chev while he was laying a skid at 8000rpm.

Anyway my 2c.

if your going to be bouncing off limiters very often, an n1 pump is a bad choice! ( have broken two)

reimax is the best i have used todate.(group A oil pumps or just get the gears & cheap too)

+1 for 5w-30 too thin for a modified. If I were you, I'd be running Motul 300V Chrono 10W-40.

interesting what do you mean by incorrect and cut corners? examples or even better, pics?

well the mechanic and i had a look at everything and what was ment to be in there wasnt, just a few different parts and he said to the conrods were not flush or not shaved off a bit to get more torque/pressure on the bearings and the bore had uneven wear and are oval an he said it wasnt oil failure.

thats just what ive been told!!!
