What Garrett Turbo Would My Hybrid Highflow Be Compared With?

so did you have a whole core and wheels purchased?? then the housings machined or was the turbo built from parts??

I gave them a RB turbo and they had the VG30 out of a Nissan Cima.They chucked the cartridge and wheels and bought a Garrett cartridge with the wheels and shaft balanced and assembled in it.Then both the RB and 0P6 housings were machined to suit.Turbo charger was then assembled.

ok its a

GT3076R 700177-5017 xxx xxx 54.97 comp wheel 52 trim xxx 54.98 turbine 84 trim

Interesting

[Risking]

how did you come to that conclusion??

The numbers provided have no reference to the actual wheels being used in the turbo only the core.

Unless they purchased an entire core with matching wheels it wont be a 3076.

I dont think the Op6 housing will actually take that size exhaust wheel come to think of it.

Without removing the housings and measuring it up and working out the trims or talking to the builders its not possible to reference any numbers besides the core numbers.

I dont think it will flow quite like yours tho

I'm not going to argue the toss.

He said it was NEW cartridge, and supplied the CHRA number off the ID tag. No suggestion of interference or modification, just a new cartridge installed between Nissan housings.

That -0017 tag equates to a 52T T04S compressor mated with an 84T 60mm turbine. That data comes off a spreadsheet sourced directly from Honeywell. Unless there was some big quality control problem, it's unlikely that Garrett got it wrong.

Given the tag number, that's what I would say is in there.

HOWEVER, those who disagree, can. At this stage all that matters is probably giving the thing a run and seeing what it does.

Once again Dale you are a wealth of turbo knowledge.Im off to Tassie tomorrow but will be getting the turbo fitted not long after i get back,cant wait.

Oh and to my original question what would the turbo be compared with then??

[Dale FZ1]

I have no claims to fame, but here's a couple of suggestions:

1. The OE comp housing may strangle the potential flow capacity of the impeller. Physical size difference between this and the .70 A/R housing Garrett normally mounts up to that impeller suggests that the mass-air flow will be reduced. By how much is a guess but that side should (guessing) be able to support 240-250rwkW - maybe slightly more. I'd reckon with a .70, the compressor would be good for 280-290.

2. The OE turbine housing normally mates up to a MUCH smaller rotor. This one MAY present an excessive restriction at higher flows, leading to tuning issues to control knock if you wanted to run big boost. Still, if it was machined correctly and profiled to match up to the rotor, it may be quite ok. I'd guess this one is also likely to run out somewhere around the 240-250kW mark.

Overall? A bit slow to come on, pretty big mid range hit but top end petering out by comparison. Again, a guess only.

Keep us informed how it goes.

EDIT: I don't think it would be directly comparable to any off the shelf item, given the specs (and assuming they are correct of course).

EDIT 2: While you have the turbo off the manifold, get someone to drill and tap a suitable location near the collector to take a nipple/bung. With VERY LITTLE mucking around you could run a temporary pressure gauge and monitor what sort of backpressure this turbine actually created. You may have seen some other discussion that focused on that issue at length. On consideration, that is what I will be doing if I remove my turbo again. Low cost, and better understanding of what is going on.

Do you think this is similar to what I have in my R33 (i was the one that sold you the injectors).

I have still been to busy to get the actual specs on the turbo I got. All i know is that it runs nicely and I dont get any boost spiking.

David, enought with the talking hey, lets get this baby stuck in so we can compare your car to mine

[The Mafia]

I'll race you both

Hi Trooper , its been a while hasn't it .

I tracked down your mate at Chippingnorton and he did did tell me the cartridge number in yours but thats about a thousand bits of paper ago . I remember he said they pressed a collar into your exhaust housing and machined it to suit the turbine which is a novel way to go about it .

The details escape me but at the time I thought it was not the way I'd go about it - something about the turbine being a little small for the compressor but its hard to be sure .

Those injectors are still in their boxes and will stay that way untill I get my hands on a Datalogit .

Cheers A .

G'day Adrian

I think soon all the specs will be 'lost' no one will remember what was put in - I dont really mind what is in there, as long as it works, its more responsive than the stock one and very streetable which is what I was after, still a shame they are not going ahead with the project.

I fried my PFC so just got that repaired at access

I am starting to get misfire problems, hoping its just a matter of gapping the plugs down.

Ready to upgrade injectors I think (again), I really want to change them but my tuner doesnt and he is the one with the knowledge. Making 260rwkw on stock injectors, stock FPR etc on 1.1 bar

Not sure what to change next. Injectors, Cams, Splitfires come to mind - but I just spent a lot of time having things tuned for economy so I dont really want to touch things for a while.
