Which Turbo Should I Use For My Project?

[Coquito]

I am in the market looking for a turbo for my 500BHP ( more or less ) CA18DET project. I have been looking at Garrett´s GT3076R ballbearing turbo but I have learned there is a "fake" and a "real" GT3076R.

As far as I have heard, the difference between the two turbos is that the "real" 3076 has got anti-surge and different compressor/turbine wheels.

I am sure the "real" 3076 would be best for my engine but unfortunately I don´t have that kind of money right now. The "fake" 3076 is almost half price in Denmark but how would it do on a small engine like mine, compared to the "real" 3076???

Which turbo would you guys use on a project like mine???

If you have some ideas I can use for my project, things I might have overlooked or something I should do different I will be glad to hear about it.

I have rebuild my engine with the following specs:

forget the fake one, as it could destroy your engine if it is a super fake one.

Why spend all the money and skimp on the main component?

Go and ask for a Garrett GT3037.

I had the 7 blade version of the GT3076 and it only made 240rwkw before it ran out of puff

Mafia:

Never said thanks for the map you sent me. It gave me a good view of how much you actually advanced the ignition. So THANKS.

But ehm... A garrett GT3037? isnt GT3037 a HKS item?

The turbo he is talking about is not a "super" fake... Its just the 7 blade version.

[The Mafia]

actually. no.

HKS make a GT3037 Pro or GT3037 ProS

Garrett Make a vanilla GT3037.

The difference is the Compressor Trims. Garrett run a 56trim, HKS use a 52 trim

[nissan200sx.dk]

Hmm, cant find it on turbobygarrett site.... ?

Do you have a product number for garretts vanilla GT3037?

OK, thanks

I will check out the Garrett GT3037R. Is this turbo better for my CA18 then the "real" GT3076R or is it more or less the same???

[wolverine]

actually. no.

HKS make a GT3037 Pro or GT3037 ProS

Garrett Make a vanilla GT3037.

The difference is the Compressor Trims. Garrett run a 56trim, HKS use a 52 trim

the current HKS 3037's are all 56 trim comps as far as i know.

The Garrett GT3037 IS the real GT3076

[STATUS]

contrary to the above comments the HKS 3037 is available in 3 trims 48, 52 and 56.

built a killer 300+ rwkw CA18 for a guy in sydney (same guy has his black 300awkw evo in current fast fours, acyually its his mums but we did the receipe )

if i was you i would be looking at a genuine HKS GT3037 as the rear housing are far superior and on a small capacity engine will make quite a differrence (on skylines the differrence is measurable but the extra money vs gain is generally to small for many to warrant it) i do alot of SR20 engines and setups and can never match the Garrets resukts to the gen HKS items except in the real small GT-RS range.

i would look at the 56trim 0.73 rear 3037S part number 1401-RA127 (450+hp) if it were mine i would run the 0.61 housing (1401-RA126) and live with a little less top end (420-440hp) and heaps more mid.

the other option is to buy the garret version and fit the HKS housings which are about $400-500 US

There's also the Tial housing options. This is Tial housed HKS GTRS:

What turbo is he running?

[wolverine]

hi trent

where can i get HKS 3037 52 trim?

what are the differences between the ProS versions and the garden variety?

[wolverine]

ok, checked nengun and i had only checked ProS versions. i found the 52 trim.

[STATUS]

turbo is a gcg "special" 3076r with tial rear housing and surge slotted cover, 260rwkw on 14psi full boost by 3500rpm on a 2litre.

i apologise but the info above is taken from another forum, I'm not personally sure on the exact specs but i saw the thing close up on the way back from QLD, we all stopped at Raleigh raceway for a quick thrash.... it is by far the best engineered car out there... bar none.

[juggernaut1]

Thanks URAS, yes GCG supplied and fitted my Tial housing too. The beauty of the Tial housings are that the T28, T30 and T35 housings all have the same size footprint. So I can swap turbo's without requiring new manifolds, gates, dump pipes.
