if you went for a twin scroll GT3071R with a 0.78 housing you could get close to 300kw with cams and it would have a stupid amount of response. but this will be an expensive route as you need a twin scroll exhaust housing and you need twin gates to do it properly.

Another turbo that people haven't suggested is ether a TD06SL2-20G for just under 300kw or a T67 for over 300 with standard cams. Both these will need external gates as both the Trust and T3 flanged housings are external gate housings.

reason i ask is volk34 had his car on the same dyna pack dyno as you a couple weeks back and made 210kw. then today at the SAU-SA dyno day at willals

his car made 162rwkw. thats a 48kw difference between his 2 dyno runs

sorry to use your car as an example volk

There is something else going on there, in the past with the older version there was around 10% difference between dyna pack dynos and other drive on chassis dynos due to no correction for wheel slippage, but the newer versions seem to be pretty much the same as most mainlines.

Your talking about a 24% difference which sounds to me like something else is wrong. Also 162 would be just under what would be expected from a standard auto R34 (don't know what car his is) or is about right for a stock untouched R33. so what mods is he running, has his car been tuned? is it running more boost? was it running the same boost in Willals dyno?

i think he has a auto r34 gtt. as for the other stuff i cant comment because i dont know.

"loksta6" you are now on notice and will receive an official warning..........followed by a ban if this slander towards a business continues.

Your post has been deleted but have attached a link to your warning fyi.

If anyone has an issue with a business, take it up with them but KEEP IT OUT OF HERE!!

thanks for all of your responses, as i had suspected gt3076 with .86 will be the one. i have all suporting mods and an eye out for some poncams. hopefully see and introduce myself next dyno day :P thanks.

i am pretty much going the same way mate

I'd get the .82 again if I was to buy another turbo. Response difference between .63 and .82 would only be a couple of hundred rpm max. And your going down the E85 route so the better flowing rear will make a world of difference when you start running higher boost levels. Come to think of it. Just get the 1.06 :D

after doing a bit more of a research your right Luke......63 and .82 rear housings dont have a world of difference in regards to response.....1.06 is in a league of its own isnt it??? :D

.63 rear housing should see me 300rwkw on 25??? mind you its going to be internal gated

ahh internally gated's a different story. get the .82.. you'll run into overboost issues with the smaller housing and IW.

FWIW mine is ex gated type .63 and makes 360 rwkw so the housing can flow more then 300 rwkw thats for sure.

While on the topic of turbo upgrades, I was looking into mix matching housings, staring with my 2530 ...

I'm thinking of upgrading the compressor side of my HKS GT2530 turbo.

The turbine side of the 2530 atm is a 76 trim (53.8 major - 47.0 exducer) wheel and 0.64AR T3 housing which I was going to keep.

Thinking of throwing on, on the compressor side ...

Garrett T04S upgrade kit

wheel: 59 / 76 / 60 trim

housing: AR70 (rated to 550hp)

Now the 2530 is internally gated. I'm looking for a responsive daily driven turbo for 250+awkw, with enough poke for track days and time attacks.

There is another T04S compressor kit, which may be too big for the 76 trim turbine ...

Garrett T04S upgrade kit

wheel: 61.4 / 82 / 56 trim

housing: AR70 (rated to 600hp).

Thoughts?

What you are in effect making is a GT2876R, they are a crap miss-matched turbo as the small turbine can't produce enough drive to drive the compressor wheel to full efficiency. The biggest i would go with a NS111 turbine wheel is a 71mm compressor which will give you in effect a GT2871R.

If you remember Ryan was running a GT2871R on his R33 and he was making 250 kw with stupid response. I would keep the T3 housing and buy a GT2871R CHRA and make up what Ryan was running

Garrett elude to the miss-match of the GT2876 when they state on the website;

* Best suited for unique applications such as asymmetric turbo installations

* Not recommended for general performance applications

Thanks for that. Now I've got a better starting point to go shopping :D

    • 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.
