Has anyone used Garrett 2560-10s yet? I want to use a pair in my wifes Tomei 2.8 thats slowly happening but would like some feed back before i make up my mind.Yes i know everyones going to suggest a big single but a GTR is twin turbo in my mind and will stay that way.

I care not for Drag racing ,Track is the place the car will be used.

Yeah arguably what makes the TO4Z cartridge is its TO4R compressor , the P trim turbine is a bit long in the tooth nowdays and long overdue to be replaced by one of the GT UHP turbines in a sensible size and trim .

The HKS version gets a leg up from housings that are not truck diesel types and can have custom AR's and diffusers to optomise for petrol performance apps .

Their GT2510 is old and old thinking compared to more modern GT28BB combinations , they learnt to lower the boost threshold by going down in comp trim rather than turbine trim and style . A couple of the SR20 spec GT-SS cartridges would be very interesting on an RB26 as they are basically a GT2530 cartridge with 60 rather than 63 trim compressors . Garrett sells this cartridge as well from memory .

Out of time cheers A .

I should grab some photos as it makes a lot more sense in pictures :mad:

I've attached a couple of pictures of the install I've finally got around to getting of the father's digicam. I've made some notes in the pictures. I'll try to remember to take some more (particularly of the front turbo and its support, and the top of the aircon outlet in the firewall) next time I have the car in bits.

Justin, as with several others, im running the HKS GT-SS's with Tomei Type B Poncams and making around 320awkw on a very safe tune.

The norm for most people running this turbo/cam combo seems to be around 315-330awkw, dyno and engine specs depending.

They are an awesome street turbo, particularly if you are looking for response.

I have garrett 25/60 and make around 228 kw at 5000 with a peak of 367 what does your car make around that rev range?

How hard was it to wrap the trust dumps? How much did you use in the prosess? I've ordered these dumps, and i'm currantly pulling out my turbo's and putting some 2530's in. (If I ever find who designed the R32 engine bay, i'm gunna kick em in the nuts)

Do you have anymore pics of your modding?

I would get them ceramic coated rather than wrap them (if I had my time again). When you put the dump pipes on the exhaust flange of the turbos the studs are extremely close to the dump pipes so fitting the nuts on is an absolute bitch, so much so it was impossible to have the wrap right up to the back of the dump pipe flange (the nut just wouldn't fit with the extra thickness from the wrap). YMMV. Some people haven't had this problem.

I can't remember how much wrap I used exactly. I bought one of these DEI Thermal kits. I am pretty sure I still have one of the 50" rolls left (but don't quote me).

I'll send you a more detailed explanation view PM.

    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell. 
    • Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂  
    • Is this a brand new LSD? if so, have you followed any break/bed in procedure for it? Usually involves heaps of figure 8 patterns, a fluid flush.
    • It's TWO steering wheels actually. 😛 one for each hand They are wheels, and they steer!
