any update stao on that rb25det gettin tuned? the one only running 9psi for now

He drove off to Adelaide, probably come back in 2 weeks to finish off the tune. I will postup result once its done.

Ok. This is our latest dyno result based on a ATR28G4 in a .64 T28 rear housing running on a build CA18det running 98 fuel. Car made 316rwkws at 24psi at this stage ( Note: see how the power curve is still rising. ). going to do a final tune in few days. This turbo would be making some mad power on RB engines using .63 rear housing.

ATR28G4 would be some thing similar to a GT3076.

Its my daily car. I drive drive it around to deliver turbos. lol

CA's modifications: Forgied pistons, Split fire coils, Nistune ECU, FMIC, 700CC injectors, Z32 AFM, 256dur/8.9mm cams, Tomei adjustable cam gears, ebay manifold and 3inch exhaust. Every thing else not mentioned are stock.

That looks good. OP6 is still small. You need .63 rear. I can get one machined for for $250. But you need to make a new front pipe. Check That exahust place next to Trents.

The guy got EPAed and defected on the way back from SA. its going to be a while before it go back to the dyno. Hoo and by the way there are plenty of ATR43's progress. The laser cutters finally got our flanges ready. So just matter of putting them together now. should have 2x samples done by weekend.

Its similar sort of CHRA. Rear housing is different. It will be a.63 Rear housing. that we made our selves. I'm plaining to make 4 different types of CHRA with 2x different sized A/R housings. which are powered from any thing at 230rwkws to 330rwkws depends on driving ability. I will post some photos once I get the housings finished.

no one does, i drive to Hoppers. Car runs 100% time on E85. Jerry cans ftw! :(

Hopefully some one starts selling it soon, im not as dedicated as you are :)

Whats the price of it now?

    • Whoa, that's a name I've not see for a long time! Sorry to hear about the engine / turbo damage.  Fwiw with any engine problems it often really a case of just seeing what happens when it's apart, ymmv - I wouldn't rule out the possibility that the damage isn't even from the turbo failure, or possibly from a combination.  The airflow between cylinders isn't dead even, injectors can go off over time as well, with the turbos overboosting if you didn't have upgraded fuel system there could have possibly been a bit of leaning out - stock triggering is often a bit unreliable by this age too.  Basically its an old engine and a few things could have been going on, and you won't know how much work is needed until the engine is apart.  
    • I'm just shocked there's a euro driver on our roads who is thinking of other road users and not attempting to blind everyone. I wonder if Prank uses his indicator too...
    • Its hard to tell really. The Q50 owner's forum talks about it a lot and has quite a few people directly affected, but no idea what % of cars sold actually had the block replaced. Also, there seem to be 2 distinct issues which both get diagnosed by Infiniti as requiring a block replacement (no wonder they are going broke) 1. "Porous block" where coolant mixes with oil through thin or poorly cast parts of the block 2. Head coolant gallery plugs not sealing. If I was noticing engine coolant loss I'd start with cooling system pressure test (as always) and then I'd pull the cam covers and reseal the coolant gallery plugs on both side before worrying about a potentially porous block.  If neither of those did the trick it would be put in a second hand engine out of japan; I haven't checked pricing but I'm sure there are plenty around by now as they've been in production 10+ years
    • To clarify what I posted above, I thought you both had a situation where it cancelled sooner one way than the other.....if it is reasonably even where it cancels in either direction that is probably normal (consider gentle movements like lane changes, you don't want it to need half a turn of lock to turn the indicators off)
    • Son, in this country, that is a piece of Gyprock. f**king drywall. FFS! I also like the autocorrect of trailer to tablet. I was reading it and thing, "what the hell drugs is he on?" Then the photo made it clear enough.
