How does the dump fit with a different core on the turbo? or are the cores the same length?

Every thing fits the way it was, they are still your OEM housings. The T2x bearing housing is few mms short. But it doesn't affect installation.

Can possibly high flow it with a BDR351 Comp wheel working with GT45 turbine wheel. Should pump out 1200HP. What sort of housing is it in?

not sure on the rear housing size havent checked yet i would only want it to flow 1000hp anyway would the rear wheel even need changing for that?

Depending on the engine size, for 1000HP you will need a 1.2 A/R turbine housing, and 87mm 85T turbine wheel. The T04Z runns of a 74mm 76T turbine wheel which is rated to 700HP, so it needs to go up in size.

Either way its not a cheap exercise so unless your T04Z is blown, its probably worth selling it and buy the T51R which we can supply at a very reasonable price.

My concern with that is if both cores ar 2-3mm shorter than the gap between the turbos opens up 4-6mm, thats enough to mean that double layered gaskets will be needed or it will leak like a sieve.

Very good result for stock Rb20det, how come its so wavy on the top? ignition problems?

It's a hub dyno so they don't have the power dampened by the rollers which usually smooths out the curve... Plus RB20's always have a bit of a wavy top end

No ignition problems at all (had a lot more boost it in and didn't miss at all)

This was with a G2 in .63, My engine blew up on dyno during the next run. Even thou that made the power and response, I still prefer .82 for high performance RB25det. unless if that was a 3576 profile.

.63 works out ok on RB20dets.

You find Rb25det with .82 rear makes power lot easier with less boost and lot less heat.

What would lag be like though? Could it make 250kw at 120kph / 4500rpm ish like that does?

only cos for me i wouldnt be at the top of 4th much on track if at all (drift), or road so thats why i was thinking the .63 could be better for that reason?

    • Yeah kids certainly add a whole another dimension to your life.  Life ceases to be about you and more about them for a while!  And I wouldn't have it any other way.  I love watching them play sport and make new friends along the way. Wow, sounds like your mate is a good guy to know!!!  He's got some serious toys in the toy box!  Yes it would be lovely to be able to do stuff to your car without getting all tied up in boring shit like how to pay for it!!  I would describe my spending style as "aggressively spontaneous and logical but regrettable purchasing"....  That will hopefully make no sense at all which would be appropriate given that is how I buy stuff.  I'll decide at the drop of a hat that I'm buying something expensive, research the living shit out of it for 2 days straight then go out and buy it.  Then I'll have instant buyers remorse for 2 days which generally passes by the time it turns up on the front step!  If I'm feeling ballsy sometimes I'll tell my wife.  Other times it just makes its way silently passed the house and out the back to the shed, never to be spoken of again...
    • My extinguisher mounted like this unscrewed a little (Maybe from the chair sliding forward) and dumped a bit of white on my mats. I'll need to get a more narrow one for future.
    • I totally couldn't do the whole kids taking up my life thing! 😮 I find it bad enough doing 45 hours in 4 days, and then fitting normal adulting life into the other 3 with no kids! As for my mates race cars, they're AMG C63 setup for production racing. The original is what has just been stripped and a brand new shell built. The original is then going away to have some panels straightened, then it will be put back together again. Then there's a third that will shortly head off to have a roll cage put in, then build it up too. And potentially a fourth to be built too... Oh, and he has two Renault Clio D class production cars, ha ha. And when he's not racing them in the Australians and QLD production championships, he's been racing one of Chaz Mostert's Lamborghini's in GT4. They just won GT4 at the 12 hour in the Lambo. We're pushing to finish the new AMG as it has its first round (and potentially its first shakedown/outing) in under w weeks for Round one of QPC, and that round is really the shakedown to make sure it's all good for the Bathurst 6 hour, which I'll be at too. Ha ha ha Working on my project is different to his, I slowly tinker and work ways to make things happen on a shoe string budget. Hes in a good position that he has a massive workshop full of parts and tools, ha ha. He also looks after me. When his air compressor died, he just needed it working, so bought himself a new one and gave the old to me. Sand blaster unit too, and a 20t pressing. And pretty much all the shelving in my shed too as he upgraded all of his (the stuff he gave me is the expensive black Bunnings heavy duty stuff)!   I enjoy working on his stuff. No decision paralysis, and anything that's needed parts wise is just there. Plus, then I get to be hands on at the track in real racing, not just club day stuff.
    • I know which one I'd prefer to have in my garage, and which one I'd actually drive as intended
    • Yeah mate, no probs. Just swap the email addresses?
