its not the 1st time ive heard this and now im quite chauffed paul, so who do u know that i know HA!

I know me...and you know me.

Mahle's are a great slug...as used by the top V8 Supercar team at the moment. Argo's RB30 rods are made locally in Maitland and have been a long proven item. The Nitto pumps are the best OEM style pump money can buy.

Now where did Marko get the idea to use Mahles.....or even RB30.........

Yes Mahles are shit hot, same as Argo. it costs a bit more than the spool stuff but IMO its worth it.

Id get a JUN pump over nitto, only because ive used them before and have experience with them :P

Good luck with the build!

stevo, you should be a sales consultant for the rb26/30 hybrid - if it wasn't for that lunch @ blakehurst rsl amongst those 80+ yr old retiree's, i probably would have stuck with the rb26

Gone for the spool kit - should have it soon..

Also a nismo oil pump (not N1)

thanks for the input guys :)

Best balanced kit ($$ / quality) i reckon. We use a similar combo for our budget builds. I hope the pdf was useful in regards to machining cost etc... please keep it to your self too :P

I am building a new motor for the drift car also Huddy so i think ill be getting some tips from you :)

Was going to go the Rb26 path but i think i might have to go with a Rb30 bottom now

you'd be crazy to go 26 path unless its well built. look at all the issue tom has had. even trent had issues with cat's motor when they first got it out but that was soon sorted.

TBH is is more important to get the rb30 bottom end right than the RB26...... especially for drift. We ran a stock rb26 for two seasons before cat killed it doing doughnuts at the gazza nats :)

Toms kept dying as no-one explained the extra oil required in the sump.

The only issue we had with cats engine was a std guide cracked and a piece got lodged in the top of a piston (causing an odd knock). The head got a full build and has had no issues since.

The new engine was spot on till i used a custom sump (supossedly the best around) and the pick up was poorly designed and caused a pressure drop @ 8800rpm. So now we run a 8litre sump designed by the boys that build High energy and ASR sumps, car revs cleanly to 9000rpm with no oil pressure dramas. Well over 400rwkw and over 600nm.

Seems the main issue with them is amount of oil in the sump. I know Toms car has always been slapped together and last time he was running of the gates spring pressure due to boost controller stuffing up. Fairly sure it seen well over 2 bar of boost so wonder why it blew LOL.

Main issue ive been having is my oil pumps. What oil pump do you use in your car Trent? i think ill PM you on a build build list :)

Cheers

oh and good luck huddy :)

ive got a set of the mahles being tested in a severe duty big hp sr20 atm and we will strip it down at the end of the season and check them versus our control engine. They are nice in fact they are ready to slot in (wieght, coating, finishing ect) and the ring kit is not bad (file fit so dont slot em in)

Many pistons are domed, JE, COSWORTH, CP etc the Trust ones we use in our car at present have valve reliefs for bit lift and duration in the dome.

      R32 Gtst - Track Car

      By bcozican · Posted

      it takes so long to get things done but ... they are nearly there and we hitting the track soon again  So - at Perth Festival of Speed the car unfortunately had a decent off, wasnt me driving, wasnt the person drivings fault. Long story short car got sent very fast towards the wall without the control on throttle from the driver input and a disaster was averted but there was damage that needed to be fixed - carbon busted and alot of bent bits The splitter got munched and had to go back to get fixed - took a bit to get it there, fixed and back but got a surprise package when a new double element higher DF splitter came back - nice surprise !  and first person to have one     At a car show I took the car too some punks stole one of my carbon indicator blanks and stomped on the other so had to get a new set of headlight / indicator combo from tops stage so got front fender vents as well to put in the order     While all this was happening the new MCA golds turned up and did some fiddling around with those   Put in the flappy paddle system and clutch lockout wiring/ system   We have also put shorter gearing in top top it out at 300 kmph in 6th gear  where previously I held 5th to 282 at SMP and 277 in Perth   Looking for better control and faster acceleration     I wasnt intending on doing pedal box I was managing with the brake master replacement system I had going on and adjusted std pedals but on applying the clutch switch to the old system we found the *insert technical word here * bar that goes from the pedal to the master was bent about 40 deg and about to snap = lucky find otherwise be a bad bad time - discussion was had about getting a custom bar built to withstand the load but in reality it was time      making any suspension, wheel or anything adjustments to date has been a nightmare - aero off, adjust, check and repeat - time consuming and hard - short of going full airjack system we fashioned some external manual car lifts this will make life a million times easier     All the bent framing, some intercooler pipes and other has been fixed and replaced and after 6 months I finally have the car back at home in my control so its get to work on it, set ride heights, wheel align and will start track testing again soon   So ultimately other than a few flashy bits nothing actually looks likes its been done but in reality alot has. Typical   We'll see how all this goes

      I'm far from an expert, but for sticking bits of metal together occasionally I got a MIG, the biggest one I could get with a 10a plug (because while I have some 15a GPOs around, they are not everywhere).  Also, because I get through SFA, I just buy the small disposable gas bottles at Bunnings, I'm not opening a BOC account to get through 1/10th of a full size bottle each year

      Ignore the BOV / recirc valve question. You have an NA and shouldn't have one. If there magically is one though... It should be removed, though it shouldn't really effect it in the way one will for a turbo motor with it venting to atmosphere while running an afm.
