Al Posted July 6, 2005 Share Posted July 6, 2005 I have just heard that the std VL turbo exhaust housing is almost identical to the VG30. T3 flange .63 a/r. I was told there was a slight differance, can't remember what, but would not effect the operation and mounting of the turbo. The flange on the dump pipe is different though, thus a custom dump whould be required. Can someone in the know confirm/reject this theory, please? Can the std VL housing be used, instead of the VG30?

Bass Junky Posted July 6, 2005 Share Posted July 6, 2005 Al, somebody said that to me too, but because the exhaust flange is different, it would make it a pain in the butt to get custom parts made up. I can't confirm 100% though. I have a guy who thinks he may have a couple for us though. VG30DET that is.

Al Posted July 6, 2005 Share Posted July 6, 2005 Great, I still would prefer the VG30det turbo exhaust housing. But if i am unable to get one, i still have my 3.5" front pipe from my previous exhaust so all i need to do is get a dump pipe made up at my local exhaust shop, no big deal really .

Cubes Posted July 6, 2005 Share Posted July 6, 2005 I was always under the impression the VG30DET housing was a .82 and the RB20/25 turbine housing a .64? EDIT: Apparently its the VG30ET housing thats a .63. Not the DET.

S3_Girl Posted July 6, 2005 Share Posted July 6, 2005 The Vg housing is a .81, i searched 6 mnths for one, and eventually paid $50 The vl is a .64 from memory. cheers darren Link to comment https://www.sau.com.au/forums/topic/78983-gcg-hiflow-hybrid-on-r33-gts-t/page/4/#findComment-1450944 Share on other sites More sharing options...

Cubes Posted July 6, 2005 Share Posted July 6, 2005 I picked mine up last night.. whahahah. I managed to pick up a second handy one that apparently works (it feels and looks in good nick) for $300. Thanks for not cutting my lunch Bass Junky. lol I'm starting to doubt it is in fact a .81 or there abouts. I've got a what was meant to be a .82 ARB GT35R machined housing. The GT35R housing is quite a bit bigger. I'll have to find out how to measure the a/r and well... Measure it!

discopotato03 Posted July 7, 2005 Share Posted July 7, 2005 Area to radius ratio is difficult to measure without sectioning (cutting up) the casting . These Hitachi housings never had the ARR size cast into them like Garrett's housings do . My impression looking at all three is RB20 type = miniscule , RB25 type = small , VG30 type = huge . They really do have a lot of volute area inside them but remember they were designed to not choke a three litre V6 . Cubes do you intent to run the complete VG30 turbo or some kind of bitza thing .

32vspecII Posted July 7, 2005 Share Posted July 7, 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. Ian what bolt on turbo can I get for 2k that makes 280rwkw ? and where can I get one ?

Cubes Posted July 7, 2005 Share Posted July 7, 2005 Bass Junky, Are you sure they don't have any? I was in there only a few days ago and they had quite a few. Your not confusing Option1 Garage with D1 Garage? Discopotato, I plan on initially running the as is VG30DET turbo, I'm keen to see how well it goes. I know the RB20DET turbo makes 175rwkw on 9psi from 4400-4950rpm. Lets see how the vg30 differs. I figure it should make 210rwkw on the dyno that I run on (rb25's make 190-200rwkw with rb25det turbo's and approx 11psi). Should be interestering too see. To be honest the exhaust a/r doesn't look much bigger than the rb20det turbo i'm running. When I was up at D1 Garage I noticed there are 2 different types of rb20det turbo's, mine and a smaller looking one. It has what looks like a smaller exhaust housing and a different designed compressor inlet, mine steps up to the compressor wheel where as the other smaller one has a smaller inlet steps down then steps back up to the compressor wheel.

Ionos Posted July 7, 2005 Share Posted July 7, 2005 Will the VG30 turbo bolt straight up as is? And does it have steel exhaust and intake wheels?

GunMetalR33 Posted July 7, 2005 Share Posted July 7, 2005 This hi-flow sounds like the perfect upgrade here, and correct me if I am wrong in saying this but cant you get a Garrett GT3071r that has a T3 flange and a Option for a nissan .63 ar internally gated zuast housing capable of making 280 rwkw easy for about 1900-2100 dollars???? If I had to make a choice between a engineered turbo and a re-engineered turbo I know what I would go for... Yes I know that its a RTA risk & you still have to run water & oil lines so add $250 and a heat shield. 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/4/#findComment-1453072 Share on other sites More sharing options...
