Without back to backing with an open 0.82 housing it is hard to tell.

On the road it drives nicely, it makes boost much earlier on the road than the dyno. I am not sure it is down on power. It is +/-10kw to most other results (excluding the outlying results from special dyno's)

Yavus felt there was an exhaust restriction based on the rate of climb and the taper at the top end. I am not so sure, it could be the old external gate (pretty sure it runs a 7-8psi spring) it could be the turbine housing maxing out. A 1 bar spring would make life easier for the boost controller. Anyone know where to get one for an old school HKS gate?

Ultimately it makes power around where it should, 200rwkw at 4100rpm isn't shabby on this dyno. I can reinstall the de-cat but 10kw or so extra top end is useless to me (assuming it is even an issue).

We could have played silly buggers and brought it all on much earlier for dick schwinging reasons but this is consistent with other Unigroup sheets.

the atp housing would probably be becoming a decent restriction at that power level, hence the top end. you could probably squeeze a decent amount more out of it with big boost though.

i have the same gate and found a mob that manafacturers copies and springs to suit a while ago but lost all the details when my hard drive died unfortunately. they are out there though, just gotta find them.

Any update on this mate?

did u sort out a new spring/exhaust restrictions and been back for a new reading?

Should make a different assume the split is from the manifold to the wheel tip of the turbo. It also makes the a/r slightly smaller then what it is depending on the thickness of the divider.

yer the a/r stays the same but the with the same a/r housing in both open and divided the divided will lose a small amount of gas area due to the divider, but this is more than made up for by the increased efficiency of the divided pulses

Well after years of having sub-standard options for going twin scroll on Garrett turbos we can now get genuine Garrett VBand Housings in open or twin scroll... will be interesting to see how these perform!

Dafarq. I was half expecting to see a fleshlight when the email notification came through :P

Hahahaha yeah it was a bit random but the inlet looks like a piggy!

They should be a good thing though hopefully!

Ahhh nice find Lithmeister! Where did you find this gem?... they had their rapid prototyped stuff at SEMA a while back, looks like they have come through with goods.

I'm well connected, and always have my ear to the ground.

(aka, I follow Turbo By Garrett on Facebook and they posted an update which I spotted while slacking off :P )

    • LOL.... a good amount of people (not all) on that continent seem to know everything and like to measure things in bananas, football fields, statue of liberties instead of the metric system lol.
    • I assume the modules are similar enough, so if you've had no issues I don't see why I would. I have tried to find a wiring diagram for the FPCM / fuel pump circuit, but I can't find it anywhere. Otherwise, I would just do some wire cutting and joining at the FPCM and give the 12 V supplied to the FPCM directly to the pump instead. If you know anyone that could help with wiring diagrams, I'd be very happy  
    • If it dies, then bypass. The task isn't difficult. I have one running on a standard R32 FPCM. That's after nearly 20 years of it running an 040, which pull substantially more current than the Walbro. They're not the same module, but I'd hope it indicates that the R33 one should be man enough for the job. I think people kill them when putting proper sized pumps on them, not these little toy pumps we're talking about here.
    • Silicone spray won't hurt anything. And if it does, that's an opportunity to put some solid steel spherical bushings in, so you can really learn what suspension noise sounds like, If you're going to try it, just spray one bush at a time, so you can work out which one is actually noisy. My best guess is that if the noise started only since putting the coilovers in, then it is just noise being transmitted up through the top mounts of the struts, and not necessarily "new" noise from bushes. But it's almost impossible to know.
    • Are you saying the 34 is SUV height, and not that we're talking about an SUV here? (because if we're talking about an SUV, you don't fix them. You just replace them when something breaks. Not worth establishing sufficient emotional connection with an SUV to warrant doing any work on one). I wouldn't jack my car up on a short little loop of 10mm steel rod poking out through a hole in the bumper bar, front or rear end. I realise that we're probably not talking about that type of loop at the front, being the one under/behind the bar on a Skyline.... but even for that one, trying to jack up on what amounts to a thin piece of steel, designed purely for withstanding a horizontal tension force, not a vertical compressive force (and so would be prone to buckling/crushing) and, my most particular bitch about it - located RIGHT AT THE EXTREME FRONT OF THE CAR, applying a load up through the radiator support panel, etc, with almost the entire mass of the car cantilevered between there and the rear wheels? Nope. Not doing that. Not on the regular. That structure out there in front of the front crossmember is not designed to carry load in the vertical direction. Not really designed to carry any load at all, really. The chassis rail that the tow point is connected to would be fine loaded in tension, as per towing. Not intended to carry the mass of the whole car, especially loaded all on one rail, with twisting and all sorts of shitty load distribution going on. No, I will happily drive up on some pieces of wood, thanks. That can only happen on driven wheels, and they are at the other end of the car, and this problem does not exist at that end of the car. And even then, I have been known to drive up on at least 1x piece of 2x8 each side at the rear, simply to reduce the amount of jack pumping necessary to get the car up high enough for the jack stands. What really really shits me about Skylines is the lack of decent places for chassis stands at either end of the car. You'd think they'd be designed into the crossmembers.
