Bullant47 Posted July 5, 2005 Author Share Posted July 5, 2005 Okay so back on topic.Hows the car at low revs know? Making any less power? Do you have a graph from like 2000 rpm upwards? Can you retain the existing dump pipe? Dying to find one. BASS OUT Hi Bass...The car is as it was with the original GCG Hiflow, spools up early. Definately have not lost any power down low.. But when boost builds up it is brutal and hits you in the back much much harder...I'm not exagurating, the car is a bit of an animal.. I have a CES split dump, but it fits up as a standard dump to the VG30 Exhaust as Stock as a Rock. No modification necessary. Brett from GCG told me when he rebuilt the turbo with the VG30 turbine housing on it that it would make 30kw@tw more....I emailed him after I got the car re-dynoed at C&V and attatched the dyno chart, and yesterday he emailed me back and said " It looks like we were right on the money eh good result" I could honestly recommend anyone with a RB25 engine contemplating a GCG Hyflow turbo upgrade to add the VG30 turbine housing at the first build.

Bass Junky Posted July 5, 2005 Share Posted July 5, 2005 Yeah pics. Any identifying marks on the exhaust housing we can look for? Link to comment https://www.sau.com.au/forums/topic/78983-gcg-hiflow-hybrid-on-r33-gts-t/page/3/#findComment-1449274 Share on other sites More sharing options...

thommo Posted July 5, 2005 Share Posted July 5, 2005 ok, to clear this up a bit, is the VG30 used here from a single turbo z31 300zx? Link to comment https://www.sau.com.au/forums/topic/78983-gcg-hiflow-hybrid-on-r33-gts-t/page/3/#findComment-1449392 Share on other sites More sharing options...
Bass Junky Posted July 5, 2005 Share Posted July 5, 2005 I believe so. I'm madly trying to find some. Might be able to find more than one.

Bullant47 Posted July 6, 2005 Author Share Posted July 6, 2005 They haven't got any. It probably worth trying the "For Sale" section in a Nissan ZX forum as well? I've tried and tried to download the pictures on here of the VF30 Turbine housing, I've even zipped it but it keeps saying that the file is too large. I took the originals on a 6 megapixel camera on the highest quality. Anybody know how i can resize?

GTRgeoff Posted July 6, 2005 Share Posted July 6, 2005 So where is the break even point on one of these compared to an off the shelf turbo producing the same power/response? Edit- basically since GCG advertise around $2K for the rebuild, plus the cost of the housing, plus the work to modify the housing, would it not be more economical to just buy off the shelf?

Bass Junky Posted July 6, 2005 Share Posted July 6, 2005 I guess the following would be about right. Turbo = free High Flow = $1950 (max) exhaust housing or busted turbo = $150 I assume the exhaust housing machining could be done when th turbo is high flowed so no additional price. Total, $2100 I think Link to comment https://www.sau.com.au/forums/topic/78983-gcg-hiflow-hybrid-on-r33-gts-t/page/3/#findComment-1449734 Share on other sites More sharing options...
Bullant47 Posted July 6, 2005 Author Share Posted July 6, 2005 Yeah, I agree with bass, for around the $2000 you get a turbo that puts you easily over the 250kw realistically and closer to 280. Is a bolt in situation, no modifications required for the fitting which is a big plus..And retains the stock look for any enquiring eyes. I know I was disappointed with my stock Hiflow struggling to get 240kw with the usual mods. I know for sure i was disappointed in my HKS cams, I thought they were a waste of money. But I think now with the VG30 Turbine housing the cams might be getting breathing space. One last thought is that I feel i'm comming to the end of my quest for more power. SK's theory of 280kw max is good for me.

Bass Junky Posted July 6, 2005 Share Posted July 6, 2005 Bullant47 What size cams do you have? I've got the Tomei Poncams, 260 x 9.15 Link to comment https://www.sau.com.au/forums/topic/78983-gcg-hiflow-hybrid-on-r33-gts-t/page/3/#findComment-1449791 Share on other sites More sharing options...
GTRgeoff Posted July 6, 2005 Share Posted July 6, 2005 So reasonably comparable for new, and a bit more than used. Sounds good, comes with warranty so a decent option for those interested. Ian, I think you are right, but find 220rwkw was too much on stockish suspension so the lod R33 needs plenty to tie the thing down. 280 would be tyre murder Link to comment https://www.sau.com.au/forums/topic/78983-gcg-hiflow-hybrid-on-r33-gts-t/page/3/#findComment-1449799 Share on other sites More sharing options...
