I suppose, at the very least, something can be taken away from these frankenfails. So having GTX 63 mm wheels jammed into a place that they don't belong netted a result that was lazier by far the

Don't feel bad. You tried something and you reported back honest results. Much respect from me. I try to do the same but this place can be hostile sometimes lol Hopefully you recover as much of the

This thread used to be interesting but now it's dull. Can someone chuck some turbo(s) in a car already and report back (preferably with skid vids)

EFR is expensive, how about Precision 6262?

Could of had EFR for the price of all these turbos you keep building and keep on getting the same shit results with!

Step it up a game, GTX3584RS would be good fun. 

Or get a GTW3884, good on the wallet. Plenty of 2JZ boys are using them and making some decent HP with good response (no idea about transient throttle).

@timmy_89 might be able to comment :)

How about a Garrett gtx3582 

 I think to put 3582 0.82 T3 Twin Scroll

and still look at the turbines mambatek. but the difference in price is not big, I think it's worth it?

Someone i know of just ran 9.6 @ 143mph with GT2860s highflowed to gtx2871r. Z32 but still gt28 housings...

Nice, good!   I don't really know what packaging constraints Z32s do or don't have but I suspect this has little relevance to low mount twin configurations on GTRs due to the reasons which have been gone over many times.  The single turbos (at least the cores) of the GT28 range are well known to be capable of decent flow in their own right, but needing the smallest possible compressor and exhaust housings, limited space for dump pipes and compressor inlets the turbo starts getting all of the worst case scenario options for performing mean that they really aren't going to perform as well as they are capable of when used as stock location turbos on RBs.

rb26 can not rotate these turbines anymore. What can I do to fix this?

1.3 bar = 491rwhp

I figured out what was the problem, the resonator created a back pressure in the exhaust system of 0.6 bar

 

I installed single mamba GT3582R (11 blades, t3 0.82 ts) on same confing

1.1 bar = 478whp

I'm going to cut out the resonator, then I'll make a graph for 2 bars

That's the resonator, or a flexible joint?  Either way.....f**k!

it's a resonator, but I cut it out

but for some reason I can not boost more that 26 psi at 98bp

Mamba turbos are good, I wouldn't be surprised if their parent company is actually making parts for Garrett as well.

Tell me more..?

Frakzz - If you want big twins in stock location, literally what ol Dosey says there might be a good starting point, Td05-18 or 20g's with billet wheels CHRA (yes thrust bearings) in a kit (including braided lines, gaskets and studs) for the same price as second hand -5's?

Acktually oil predates dinosaurs by a few 100 million years :P

hahaha. Nice.

But does it predate Godzilla? Didn't he kill off the dinosaurs? or was it a man in the sky

      After market rear camber arm adjustment

      By Duncan · Posted

      Then, shorten them by 1cm, drop the car back down and have a visual look (or even better, use a spirit level across the wheel to see if you have less camber than before. You still want something like 1.5 for road use. Alternatively, if you have adjustable rear ride height (I assume you do if you have extreme camber wear), raise the suspension back to standard height until you can get it all aligned properly. Finally, keep in mind that wear on the inside of the tyre can be for incorrect toe, not just camber

      I know I have to get a wheel alignment but until then I just need to bring the rear tyres in a bit they're wearing to the belt on the inside and brand new on the outside edge. I did shorten the arms a bit but got it wrong now after a few klms the Slip and VDC lights come on. I'd just like to get it to a point where I can drive for another week or two before getting an alignment. I've had to pay a lot of other stuff recently so doing it myself is my only option

      You just need a wheel alignment after, so just set them to the same as current and drive to the shop. As there are 2 upper links it may also be worth adding adjustable upper front links at the same time; these reduce bump steer when you move the camber (note that setting those correctly takes a lot longer as you have to recheck the camber at each length of the toe arm, through a range of movement, so you could just ignore that unless the handling becomes unpredictable)

      I got adjustable after market rear camber arm to replace the stock one's because got sick of having to buy new rear tyres every few months. Can anyone please let me know what the best adjustment length would be. I don't have the old ones anymore to get measurements. I'm guessing the stock measurement minus a few mm would do it. Please any help on replacing them would be fantastic I've watched the YouTube clips but no-one talks about how long to set the camber arm to.

      Heh. I copied the link to the video direct, instead of the thread I mentioned. But the video is the main value content anyway. Otherwise, yes, in Europe, surely you'd be expected to buy local. Being whichever flavour of Michelin, Continental or Pirelli suits your usage model.
