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 .

      Boost cut after swap(RB25DET NEO) R34

      By Kapr · Posted

      Ok thanks..that was my second question if i can somehow bypass this even with Nistune(that is all i have right now...aparat from stock ECU. So with some aftemarket it can by "bypassed" or make it work?  I know there is Link or Haltech (mainly used). We have ECUmaster here so i will gather some info about it.

      Yes. You will need to get the original boost sensor and wire it in. That is.... if you plan to use a stock ECU - even a Nistuned ECU. The Nissan ECU will not operate correctly without it connected. And yes, it will do annoying stuff like you are experiencing. You will almost certainly be better off with some aftermarket ECU, than trying to hunt down rare sensors.

      Ok so ABS/TCS is "not" the problem. Yeah i know now about the ABS with Nistune(i told that to the Nistune guy) but iam not 100% why or why i dont have ABS. ABS cube is in the engine (always has been) but i had braked couple of times rly hard and brakes just locked and scream. Does all Skylines have ABS cube? That boost sensor https://www.sau.com.au/forums/topic/367633-wtb-r34-gtt-turbo-pressure-sensor-pics-inside/ Is this it? I need to ask but i have a picture of engine bay and i do not see that (100% is not in that place) If i do not have this the car can do what mine is?(cutting around 4000 rpm) Here is the pic of my engine bay(only one i have) BUT i think i dont have that cuz loom was used from my RB20DE NEO and i know (obviously) that it does not have boost control or any wire to that...) so maybe that is the problem? (i dont know for 100% if that car where the engine is from had that)...but i dont have the loom from that

      S1 rb25/s14 starting problem

      I'm with you here. It's either loom has an issue, OR, injectors are not functioning properly. It could even be they're just constantly dribbling, hence the wet, but not firing.

      Depending on how long the car sat it is very possible for injectors to be stuck open or closed, I'd get them cleaned and flow tested. Other than that, obviously when the loom changes and the car doesn't start any more....the loom is suspect so some tracing / comparing may be required
