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:

Engine is balanced to 8500 rpm.

Apexi Power FC + Commander

Wiseco forged pistons ( 1 mm. Oversize ).

Pauter connecting rods.

Standard crankshaft ( Knife edged, regrinded, balanced and kryo treated ).

Treadstone intercooler ( Core size: 550 * 200 * 90 mm. ).

Dump valve ( Aluminum. Adjustable. 51mm piston. )

K&N large Air filter.

Nissan Q45 throttle body.

300ZX Z32 Air Flow Meter.

Walbro fuel pump ( 255 L/min. ).

Sard adjustable fuelpressure regulator.

Sard 800cc fuel injectors.

4” stainless steel frontpipe ( Homemade ).

3” stainless steel exhaust pipe ( Homemade. No cat. ).

2.5 “ stainless steel intercooler pipes + silicone couplers.

Cusco race engine mounts.

Apex performance short shifter kit.

Brand new radiator ( Same size as OEM radiator but twice as thick ).

2 electrical fans.

Oilfilter relocation kit.

Innovate motorsports wideband sensor.

Datalogit logger ( for Apexi Power FC )

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.

I've emailed you a speadsheet with them all on it

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.

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

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.

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.

    • Personal experience. Those f**kers burn. And are actually a PITA to put out. Next time I walk down the back, I'll snap a photo of what the inside of the bonnet looks like when that thing ignites. PS, powder fire extinguishers are useless on that stuff too as it's fibrous and when it ignites, it starts to pull apart. And you end up just blowing powder through a sieve effectively.   Like the big thing is, if it's fire resistant, it's job is to stop what burning? The METAL above it? It's just to try keep heat off the bonnet paint work.
    • Oh man, sorry, $60.00000000... 😛
    • That's more or less what he meant. What it really means is that you do not have to go full crazy on the build. Don't need the best oil pump, expensive rods & pistons, big cams, etc. You can upgrade whatever you want instead of using stock level items, but you don't have to. Having said that - any time an RB is opened up, if anything is getting replaced, I think the opportunity should be taken to do all the sensible upgrades. Pistons, rods, pump, etc.
    • February update 🙂 We managed to get the very last 1/18th "Extra Scale" cars stock available from bookstores in Kyoto. These are actually the last ones and will not be restocked again! Hachette Collections Japan have not decided on a release date for these or other models in the series, so for the time being these are all there are available new.  These are showing up on Yahoo auctions at inflated prices already (especially the Celica and NSX) so get yours now at a very reasonable price before they disappear! Stock quantities: NA1 Honda NSX - 1 left: https://www.oemsoko.co.jp/products/1-18-extra-scale-1990-na1-honda-nsx 1973 Toyota Celica LB 2000GT - 2 left: https://www.oemsoko.co.jp/products/1-18-extra-scale-1973-toyota-celica-lb-2000gt 1968 Mazda Cosmo Sport - 2 left: https://www.oemsoko.co.jp/products/1-18-extra-scale-1968-mazda-cosmo-sport 1970 KPGC10 Nissan Skyline 2000GT-R - 2 left: https://www.oemsoko.co.jp/products/1-18-extra-scale-1970-kpgc10-nissan-skyline-2000gt-r
    • When you say basic rebuild, you mean an oem rebuild?
