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.

    • So to further complicate things or hopefully explain better: This is a VDO sensor. It clearly does this math inside the gauge itself... because it displays a temperature in C to me instead of a voltage. The signal wire to the gauge is in Volts, not Ohms. I have just teed into this and sent it to the ECU. ChatGPT spat this out: Temperature (°C) Thermistor Resistance (Ω) Voltage Output (V) -40 36563.56 4.973962698 -35 26284.63 4.963854097 -30 19149 4.950518086 -25 14127.68 4.933166097 -20 10504.68 4.910527969 -15 7721.35 4.879055954 -10 5720.88 4.838133512 -5 4284.03 4.786165799 0 3240.18 4.721119717 5 2473.6 4.640900563 10 1905.87 4.543692515 15 1486.65 4.429695182 20 1168.64 4.296344225 25 926.71 4.144091368 30 739.98 3.972492431 35 594.9 3.782907287 40 481.53 3.577860996 45 392.57 3.361217186 50 322.17 3.136573398 55 266.19 2.908608143 60 221.17 2.68039363 65 184.72 2.455599277 70 155.29 2.239608872 75 131.38 2.035132288 80 112.08 1.846579676 85 96.4 1.674774149 90 82.96 1.511882199 95 71.44 1.359001674 100 61.92 1.222169588 105 54.01 1.100403407 110 47.24 0.989775394 115 41.42 0.889528391 120 36.51 0.800974069 125 32.38 0.723478416 130 28.81 0.654148313 135 25.7 0.591893137 140 23 0.536380597 145 20.68 0.487551867 150 18.59 0.442640126 155 16.74 0.40213318 160 15.11 0.365841848 165 13.66 0.333073247 170 12.38 0.303758956 175 11.25 0.277572169 180 10.24 0.253917873
    • Can you measure resistance between the pin you're wiring to, and the sensor ground?
    • Not 10 out of 10 crap. But just so......disappointingly....bleh. Just didn't do anything well. Everything was bland. Didn't even have a long enough life to justify the ongoing daily disappointment. Although I was so happy to see them go that I'm glad they didn't last longer.
    • Not enough to make any difference at all.
    • Don't they cool down technically when you're sitting at a set of lights?
