50cm?? Thats half a meter before.. Is there even half a meter of pipe from cooler to TB?

I'm sitting inside and haven't looked at it for a while, my judgement of distance is definitely off haha.

It's near enough to where the pipe comes through my cold air box.

I was reading through the thread and was going to weigh in anyway, though looks like you're very much on the page I am reading from - so I'll +1 with with a bit more anecdotal evidence to support it

The ATR28SS15 would be a perfect turbo for your application. I didn't look into some thing even smaller as it doesn't make that much of a difference in response but did loses quite a lot of power. I'

^ lol... maybe I'll use a 3" intake pipe and add in more bends.. that usually gets the suuuuuuuuuuuuuuuutuuututuutut going LOL. Anyhow, some real world facts to back up the results.. errbody likes ti

You want it to be as close to the compressor housing of the turbo as possible. If your running actuator pressure you can also pop a nipple on the comp housing and run it straight from there to there.

Why is this, exactly? The only reason I can think of is to avoid overworking the turbo if your cooler is a restriction, but at such a measly boost level that I'm running I can hardly see that being of concern.

Actuator reaction.

If the surge is created by a minor overboost at those revs/throttle then moving the reference nipple will mean the actuator reacts quicker and can overcome the problem.

Thats assuming the surge is created by that specific issue.

Okay so the reply back from JJR is that all there dumps/front pipes are the same so mine was not a defective product.

No no What they are saying is, All my dump pipes are defective. You like you buy.

I might look into having that done then - would the turbo need to be removed to put a nipple on the outlet though? I would think this would only be for safety reasons to avoid metal shavings falling down to the compressor.

To make it simpler just get one welded on the cooler pipe as close to the turbo as possible.

Should work to the same effect mate.

Stao is it possibly you can produce these with a nipple on the cover from now on?

I was a little :( when I didnt find a reference nipple on mine but there were 2 casting marks indicating where it could be fitted.

^^this. I welded an 1/8 npt socket onto the underside of the pipe out of view then screwed a barb fitting in

cbf, lol. But yeah if (when) I next remove the turbo I'll have one put on the comp cover for sure.

Yes I have stock of the billet 20G but only in a 10cm T3 rear. I can sale you the core for $700 if you want, which you can run that in your current 8cm housing.

18G, and 25G plus 8cm turbine housings are still work in progress at this stage.

Ok , so what are the advantages of billet wheels compared to the ones on the one i have now? (just talking myself into it really, just seeing if i can justify the extra $$) the car that the turbo will be going on will be used mainly for track work so it will get a hefty work out!

Well if the comp wheel is made exactly the same to original caste then it makes no differences. lol

For our billet wheels we run a different sized hub with slightly taller inducer and blade curvature. All manufactures has their own wheel profiles, so there won't be an identical billet turbo result.

The currently 20G follows our SS hub and blade profile, that is engineered to produce the most Power with Least RPMs. So the car comes alive as soon as its on gas. You can see that worked extremely well refer to test result based on a SR20det None Vct motor, and no one has yet managed to get 200rwkws by 4000Rpms on same setup. Its going to be crazy responsive working with the Rb25det. I would expect the end result be similar to the SS1PU with more top end since working with proper manifold and external gate.

I reckon i might get a 8cm housing and one of these Billet 20G's and jam it on the 4AGZE Ke10 rolla i have here with some E85 in the mix..be epic on 30psi..lol

have a killer ex manifold here for one, be a shame to waste it..lol

cheers

This is a pretty good result from a high flowed Rb20det turbocharger bolted on to a stock rb20det motor internally gated. Green is 98 and red id E85 limited by fuel pump. Hopping to see around 250rwkws with fuel pump replaced.

For 4AGZE Ke10 rolla, Here's a result from a ATR28G2. Good chance cracking 300rwkws on 24psi on e85 :yes:

      ER34 AT ECU and HKS SLD pins

      By GoHashiriya · Posted

      Hi all, I need to get this HKS SLD attached to my stock ECU because I've now got the German autobahn and faster European circuits to contend with.  The car is a manual 2dr ER34 with an AT ECU and I've realised the AT ECU has two pins for speed sensor signals: Pin 29: Vehicle speed sensor signal (Vehicle speed sensor 2) Pin *58: Output shaft rotation sensor signal (Vehicle speed sensor 1) - *RB25DET A/T model only Before I go butchering this harness, is anyone sure of which pin is the correct one for signal adjustment? The attached document from HKS indicates pin 29 but I found this situation mentioned in the following thread on a different forum (R34 GTT Auto Trans Speed Cut Problem | Zerotohundred) mentioning pin 58 needing to be altered by member zephuros, albeit it seems to be for an RSM-GP and the info appears to be old.  R34_All_Workshop_Manual-pages-2.pdf R34_All_Workshop_Manual-pages-3.pdf R34_All_Workshop_Manual-pages-1.pdf HKS SLD Vehicle Pin out P59-P70 ER34-pages.pdf

      People like Johnny Dose Bro might be laughing at my post because I accidentally added 100mm to my numbers. 350-355 is indeed the lower limit. 450 is off-road Skyline spec.

      What is the "compromise" that you think will happen? Are you thinking that something will get damaged? The only things you have to be concerned about with spherical jointed suspension arms are; Arguments with the constabulary wrt their legality (they are likely to be illegal for road use without an engineering certificatation, and that may not be possible to obtain). A lot more NVH transmitted through to the passengers (which is hardly a concern for those with a preference for good handling, anyway). Greatly increased inspection and maintenance requirements (see above points, both).   It is extremely necessary to ask what car you are talking about. Your discussion on strut tops, for example, would be completely wrong for an R chassis, but be correct for an S chassis. R32s have specific problems that R33/4 do not have. Etc. I have hardened rubber bushes on upper rear control arms and traction rods. Adjustable length so as to be able to set both camber and bump steer. You cannot contemplate doing just the control arms and not the traction arms. And whatever bushing you have in one you should have in the other so that they have similar characteristics. Otherwise you can get increased oddness of behaviour as one bushing flexes and the other doesn't, changing the alignment between them. I have stock lower rear arms with urethane bushes. I may make changes here, these are are driven by the R32's geometry problems, so I won't discuss them here unless it proves necessary. I have spherical joints in the front caster rods. I have experienced absolutely no negatives and only positives from doing so. They are massively better than any other option. I have sphericals in the FUCAs, but this is driven largely by the (again) R32 specific problems with the motion of those arms. I just have to deal with the increased maintenance required. Given how much better the front end behaves with the sphericals in there.....I'd probably be tempted to go away from my preference (which is not to have sphericals on a road car, for 2 of the 3 reasons in the bulleted list above), just to gain those improvements. And so my preference for not using sphericals (in general) on a road car should be obvious. I use them judiciously, though, as required to solve particular problems.
