its the stock turbo what do you expect? its small for a 2.5L its way too small for the 3L.

does drive nice in traffic though, boost from 1500.

Oh damn... it is a 4.0L straight six though; you 3.0L boys are all about capacity aren't you? Are you sure you don't want to buy it and mate a RB head on the bottom end...

It was for the guy asking what it would be like with a stock turbo..

Another one i heard somewhere thats stuck in my mind;

"Anything an RB26 can do, an RB30 can do better"

Rb30 never won bathurst

Rb30 never won bathurst

Never got the chance did it?

The race R31's didnt use 3L

[Sir Lord Van Von Vader'ham]

mine does.

What sort of NM's are ppl getting. i know driveline changes it a bit but just curious.

nah the Group A R31's had the Rb20

so RB20 > Rb30?

Lol

p.s im only stirring

Mine made about 7000 tractive effort. when i worked it out (iforget the formula) it was like 530mn.

Seems a little low

My engine in its' old car with a pair of 2540's made ~600ft-lbs (~800Nm)

540nm @ 4700

320kw @ 5700

Your distinct lack of emoticons makes it hard to tell

I actually changed diff ratios because it didn't rev.. lost ~2000rpm in each gear so changed from 4.3:1 to 3.9:1 and picked up speed in each gear again. Like TiTs said, it made boostwell early, I think it was actually making positive airflow at idle (not pressure, flow). I had to tighten the bov right up to stop it leaking at idle.. you would think that a leak like that would be a VACUUM leak.. sucking air in.. but it was pushing air out!

IMO an RB30DET with an RB25 turbo (with OP6 rear, wouldn't choke up by 5800rpm) is how the R32GTSt should have been released from the factory! The inspector that passed it over the pits was well impressed

Mid 700's from memory

There are 2 types of people in the world, Those who have 30 bottom ends and those who will.

[joe blo]

im thinking bout putting a hypergear powered up highflow turbo on it. its a 500hp unit with .82 rear. his makes 305rwkw on a rb25 with all standard cams and crap. how mad will it be on my rb30? super fast and stuff? wheelspin everygear?

[TiTAN]

see how similar the power / boost curve is compared to a 3076 then make a rough guess based on AL's dyno sheets in the RB30 upgrade thread.

My dirty 30 is almost ready to be boxed up to be sent to be fixed. After almost 12 months (having lost interest and built a new house) I want to get it fixed and hope to get some ks on it this time.
