Garrett GT35R 714568-1 or -2


Recommended Posts

Hi Mr Walker, what is your power target? What capacity engine? What are you aiming for with the car? Road, drag, circuit or combo?

The reason I ask is we have used a GT35R with the 1.06 A/R turbine and it works very well on a 3.1 litre engine with a 700 bhp target, that has a close ratio gearset and is targetted at a road/drag combo. This engine also has a lot of other parts, cams, ported RB 26 head and manifold, forged rods and pistons, valve springs, head and main bearing stud kits, etc etc.

However if you have a 2.5 litre with limited mods and want a road only car, then I would not recommend it.

Hope that is of some help

Hey SydneyKid,

In a word....YES. You've pretty much outlined what I have in mind. An RB30 with an RB26 head and associated paraphanalia and mods as mentioned, with the intention of lots of street and regular drag racing sessions to bring out the peak. I was aiming at 600+ bhp. Would the .82 be more appropriate for this power target or would you suggest I reconsider my turbo choice? I want to use off the shelf Garrett equipment rather than any Japanese brand names...

Hi Ghost Who Walks, your power target is pretty much what I would aim for in one of our ciruit race cars, the low 600's seem to be the go for maintaining good response with sufficient power. A vast majority of the Japanese circuit attack Skylines have this power level. For a turbo we use a Garrett (what I call) competition core, this enables lots of choices of compressor and turbine. The main advantage is, being designed for racing use, they are easily (inexpensively) serviceable and rebuildable with off the shelf parts.

Have a talk to your local Garrett agent, they should have the details.

A skyline i drive in reguarly uses a built RB26 with a 2.7 capacity, and associated headworks, he has a GT35R with a 1.06 housing and the car has good response low down in the rev range, seems to hold the power well all the way 7500-8000rpm. Has run a smidge over 470rwhp.

Hope that helps

I have this turbo sitting in my room for my RB25DET. Just wondering how it compairs to the turbo's you guy use down there? It's a standerd bushing turbo. Here are the specs.

56 trim GT40 compressor wheel

-76 trim T350 turbine wheel

-T04E (3" inlet, 2" outlet)

.63 AR exhaust housing.

    • TCU is enroute, should be here on Monday. Have just paid for a transmission locally, they've got to pull it out of the car and should be with me on Friday. Just getting little bits and pieces I need for wiring. Thinking about using a small bulkhead connector to run the transmission wiring through the tunnel as the trans plug is quite big.  So all going well i should have the box dummy fitted up next weekend and start wiring.
    • sure, just PM me your email....
    • Haha likewise, take my shit box for a spin and maybe you'll end up wanting a R33 shit box again lol...  
    • @Jasoncauser looks like a tight technical track, and definitely fun! Let's hope I make it to that day 😎  
    • The springs just lets the valve bleed off pressure/oil and it bypasses the feed gallery and heads back to where the pickup feed is On the LS the oil gets the the bearings...eventually  This vid explains the OEM pump well IRT the pressure release valve and how the bypass works The oil pressure light coming on intamitantly could just be a sticky valve, but, why pull something apart and not put something better in  I believe the low oil pressure light comes on somewhere between 5-10 psi Well will stick a gauge in after the installation to see what difference it makes at hot idle and higher RPM, and by high RPM I mean 6300 RPM.....LOL
