Hey all,

Im torn between a Hi-flow or a new HKS GT-RS.

Looking for some personal opinions here from people who have used either of these or have had a chance to compare them.

Looking though some threads ive noticed the GT-RS has a slightly better power curve on the dyno but was wondering does it justify the extra cost for what seems to be a relatively similar peak power to the GCG hi-flow. I'm chasing street response, no lag monster suggestions please! :P

Well all opinions are welcome!

Thanks,

Dragonforce

I"m running the GCG high Flow.

I've been really happy with it. It makes good power and with cams, I've got a pretty fat power curve.

Check out the Dyno graph comparison website in my sig, and have a look at the power curve between my car and some of the GTRS equipped cars.

If I could have my time again, I would probably have gone GTRS or probably even 2835ProS.

At the time of getting my turbo, I'd blown the old one and the fastest way back on the road was a high flow.

Someone here PM'd me just the other day saying they really like their HKS GT2835 Pro S 0.68 A/R on an RB25DET .

The full kit may look expensive but they give you everything to make the turbo fit like all lines a dump pipe etc .

The call was that its very similar to the std pea shooter turbo right down low but comes on reasonably quickly - like a road car turbo should .

This person thought through someone else experience that the 0.87 A/R exhaust housing option cost that nice low-medium range squirt and for the small amount of top end it wasn't worth it on an RB25 .

The guts of it is that the 2835 Pro uses a slightly larger trim version of the same compressor family as the GT-RS uses .

Turbine wise its a little larger and a different family to the GT-RS's one .

Exhaust housing wise the Pro S one is a MUCH better design and with the 2835's turbine will make more power for stuff all difference spool wise .

Like with any change to a turbo engines breathing abilities you HAVE to tune it properly to take full advantage of the upgrade . This kind of thing is a bit beyond what the std computer wants to deal with and dito for the std SMIC .

Sounds like a real nice can live with it everyday road car option to me .

Cheers A .

      Yes...but look at the numbers. There is a tiny tiny fraction of the number of Joules available, compared to what is used/needed. Just because things are "possible" doesn't make them meaningful.

      Somehow Vertimass/Oak Ridge National Labs has figured out a catalyst that can convert ethanol into C9-C10 hydrocarbons in basically a single step without ending up with a bunch of ethylene or similar waste products: https://patents.google.com/patent/WO2023224867A1/en I still don't think anything like this will keep us from needing to transition to EVs regardless along with all kinds of other electrification, but things like this will go a long way towards alleviating the problem of how to electrify things like planes. Renewable diesel is seemingly an easier problem as well, Chevron is already running refineries for the stuff and the primary feedstock is tallow and other waste fats from agriculture.

      Ok so I have sorted everything with my uniclutch and  i can offer up a bit of feedback and some things that might help others.    I found problems with factory damper line. Weird shit and had trouble with peddle adjustment    I used this https://au.gktech.com/products/r33-gts-t-skyline-braided-clutch-line?_pos=2&_sid=22b01b9b9&_ss=r Also when adjusting peddle leave a bit of play. You can get into a over stroke condition easy.. Make sure you can push the slave forward after adjusting to confirm fluid can return to master then you will need to pump it up heaps…..not sure why but that’s how it is.    last thing the splined adapter is machined perfectly. If your input shaft is old like mine was I would put a bit of valve grinding paste on it and stroke it like a 15 year old. Just to give it a tad more clearance and to better match it to the spline.    reason is on a near flat shift I have had situation where the peddle returns a millisecond after you lift from the clutch. No slip or anything but I reckon this is due to tolerance on the spline being way tighter than stock clutch and binding for a sec. I think this will go away but also my spline was old. Box is old so I guess I should have checked better. It’s a super neat fit.    it feels light as and holds awesome without any noise
