Interesting info ...:

HKS official Japanese web site http (//www.hks-power.co.jp/) rates their new(er) GTSS power output equal to their GT2530 at 320PS. This is perplexing in that the official HKS Australian web site rates GT SS at only 280ps and 2530 at 320ps.

Also the "new" Trsut T517Z's now look to be superior to the HKS items as they flow alittle more power and come onto boost earlier than the 2530's but probably later then the GTSS's.

Anyone gone from GTSS's to T51's ????

note; image below is HKS dyno graph for GTSS's !!! ... comments ?

I was under the impression that all of japan and europe get 100RON aswell   I'll say this: don't get too hung up on Japanese brands. A few of them make a few good things (tomei oil pump, nis

Jeremy, The 25/30s will make around 70rwhp more than your R34 made last time on the Dyno but with a very wide power band plus they can be had cheap these days.

Guys,

How do you insert an image into these messages (Im not too bad on computers but this has got me Fked)

I know someone who has Trust T517Z turbos in a GTR. Spools up around 3300rpm, starts pulling like a freight train after 4000rpm@ 12 psi. Higher boost + cams etc will see these babys pull well over 300awkw.

Quoting "Club Skyline" A Japanese tuning mag the Trust T517z turbos were designed to fit between HKS 2530 and HKS 2540 range.

But if I was in the market for turbos, the New GT-RS would be my choice.

Hi guys, as I see more of the results from twin GTRS's it starts to look more and more like they are a bit too big for a standard internals RB26. OK on 2.7 litre and 2.8 litre engines with high rpm limits (9,500 rpm plus). Just a little late building boost in the rpm range with 2.6 litres and the standard rpm limit.

Of course if HKS published compressor maps we wouldn't have this problem of having to wait for other people's results and they might actually sell more turbos faster. But I'm not holding my breath on that one.

Hi guys, moving onto T517's, no water cooling and no ball bearings, so long term reliability has to be a consideration. The most tricky bit is their wastegates open the other way, this makes using the common designs of split dumps almost impossible.

I'll pass thanks.

Uhh...ohh, i think you will find that BB turbos can be rebuilt, but if i owned a BB turbo i wouldnt be too concerned about the need to get them re-built.

Your likely to damage a turbine/compressor thru dodgy filters or engine crapping itself, before needing to rebuild the turbo's core/cartridge...that said if your buying 2nd hand, being able to cheaply re-build ($400) a bush bearing turbo is comforting.

      Anti Squat Kit

      By robbo_rb180 · Posted

      What are you doing with the car? street car or race car? People get hung up on the squat of the s/r chassis rears. There is positives to the squat if a car is setup and driven correctly for it (correct ride height, spring rate, alignment, damper valving). Generally just lengthen the rear traction arm by 5-10mm and that will help the squat and bump steer too. You are also correct with the roll centre too. This too also needs to be adjustable if you start messing with suspension geometry.   Having done quiet a bit of testing on race cars this year in regards to rear squat, I've seen some big positives from it in regards to drive off corners and traction.

      I find I am using the MX5 for everything except long overnight cruises with Jackie, or, if picking up the kids to go somewhere, the SS has so much more room inside, and is much more comfortable if your going to be doing Hwy driving for 6-8 hours And the MX5 isn't bad in stop go traffic for a manual transmission car, whilst the clutch kit has been upgraded from stock, it is still light, and also not having a stupidly light flywheel in it helps as well, I've spent alot of time sitting on the M5, M4 and M7 stuck in traffic when plodding around the Greater Sydney Region in it Another benefit is MX5's are not really a car that gets stolen, you can pretty much park it anywhere, and it will still be there when you return

      I can totally get why you like it for that sort of commute. I was thinking BoganDore because it's such a lazy drive, for things like stop start traffic.   I used to do over an hour in stop start shit from one side of Bris to the next, twice a day. My choice of car was larger displacement, with an auto. Basically for torque in low rpm/very low speed, and no clutch pedal. But loved a fun manual for the weekends, which the partner has (plus had the LandCruiser too for other fun drives). I now have an EV as a work car, and I tell ya what, ultimate daily driver, especially if youre out of energy, like I often am after work. I don't even need to touch the brake pedal   That said, I'm presently rebuilding the Liberty GTB to get it setup for weekend drives and track abuse! So small high revving turbo engine with 6 speed cog swapper!   But for your style of commute, I'd probably take the MX5 too!   For those choices, I'm ignoring fuel economy. Because I know how atrocious V8 daily life is for fuel from when I used to daily a manual SS, ha ha. Hence why I know I love the daily rumble of a V8

      People just don't understand how good MX5's actually are and how fun they are to drive, park, manuever. You feel like you have got some fun cheat code, while everyone else is sitting in their luxobargeSUV like normies who missed the point of living. It really is that noticable. As long as you/your stuff fit, and you're comfortable (they are), a MX5 is the best car on earth to daily around.
