XGTRX Posted March 20, 2016 Share Posted March 20, 2016 (edited) It was. Linear, quick to fall back into its stride. I would 100000% prefer that than a set of -5's (let alone a set is RS's) on a stock engine. Makes me very curious to see what a 3582R would do on the same setup, being smaller. That was an old dinosaur garrett Z, open scroll, single gate setup. The Zs work well don't they.[emoji2] [emoji2] [emoji2] Don't know what it is with the 35s but they don't seem to come back on as quick in between gear changes, where dyno sheets makes them look better than what they are in my experience. Its good to see u experienced the Z first hand, dynos tend to lie about a lot of things, but its a fun turbo that's for sure.

s2d4 Posted March 20, 2016 Share Posted March 20, 2016 (edited) Yet to see a GTW result that is half decent.I would assume twin scroll, billet compressor wheel and ball bearings would make some difference compared to the dirty T04z you tested? The old T04z dynos never looked any good really. People actually use to look at that and stay with the twins.

XGTRX Posted March 20, 2016 Share Posted March 20, 2016 Yet to see a GTW result that is half decent.Old Z with a newer style billet compressor with a bit of cleaning up comes on 300 or so earlier. Pretty much what a GTW does, yet people always claim more response, like 500 rpm, yet to see it though.

Dose Pipe Sutututu Posted March 20, 2016 Share Posted March 20, 2016 Because most GTR owners run those T04z in single scroll. To really harness any motor vs. turbo application is to go twin scroll to reduce back pressure on each pulse as well as rely on scavenging. The more the motor breathes, the more torque and power it will make. Simple combustion engines 101.

Got out of it with a smile on my face.I'm not shy to express my hate for 2.6L's. They suck. But I'd rather a 2.6L open scroll, dirty old Dinosaur T04Z than a 2.8L with RS's as much as I hate to say it. Call it what you will. I'm VERY critical of a setup.

I wasn't having a go nor do I like RS's.Was just saying that you would like the gtw more than the old z, dyno or no dyno considering you like the z and that generally has not so nice dyno curve.

Was just saying that you would like the gtw more than the old z, dyno or no dyno considering you like the z and that generally has not so nice dyno curve. Well, the same can be said about the GT vs GTX. And the jury is still out on those as they take a shit load of boost to reap the benefits. Yet to see a gtw impress on an RB in the real world. As piggaz found out the old BB Zs aren't as bad as people make them out to be and their performance aren't really reflected on a 4th gear WOT run on a dyno sheet. As with so many perceived laggy dyno sheets, the real world says different. 1 Link to comment https://www.sau.com.au/forums/topic/463295-opinions-on-hks-gtrs-on-a-rb26/page/3/#findComment-7700458 Share on other sites More sharing options...
Piggaz Posted March 20, 2016 Share Posted March 20, 2016 If I could draw a comparison. The low end fell between a -9 and a -5, yet made 450 kW. This was the most basic jurassic park setup there is. A proper twin scroll manifold, twin gates, two scroll ass end housing would have made it better no doubt! "Twins for response" is a little upsetting when a dinosaur open scroll Z punches hell out of -5's on an equivalent engine.
