Hello all in Australia, :)

I have looked around this site a bit and you all seem to know your stuff and have many interesting threads on the site that have been very helpful....

I have read a lot about the GT2860R turbos with good reviews on here so far (its the -5 HKS2530 equiv)

I Have ordered these turbos and am looking to fit them next week and get the car mapped up.

So far im running:

87mm JE Pistons,

new bearings

HKS 264 Camshafts

uprated fuel pump

uprated FPR

denso 550cc injectors

trust elbows

downpipe decat and exhaust

induction kit

HKS hard pipe kit

Power FC ecu and boost kit

OS Giken STR twin plate clutch

HKS Steel head gasket

Apart from a refresh 2000 mile ago with better bearings etc the bottom end is STD ! no uprated rods for me and a std gearbox :)

Because of this i am thinking no more than 550BHP at the fly ? I am therefore aiming for 550 exactly hehe

Does any1 on here run these turbos and what are you making power-wise with lag/response/torque etc ?

Any help is muchly appreciated guys as no-one in the UK hardly has these turbos yet....

Heres a pic or 2 of my car >>>>>>>

Hey Peter, glad to see someone running a 32, seems like alot more 33's and 4's over there.

I'm using these turbos on my R32GTR, dont know if my numbers will help you though. My engine is standard internals with adjustabke cam gears, dumps etc and Power FC. It makes 406 hp at the back wheels at...from memory as i'm in off-shore at the moment, at 16 psi. Just about maxed out the stock injectors. As kwazza11 said check out the rb26 turbo upgrade sticky

Good luck and keep us posted with your dyno results

Thanks all for the responses guys,

Im lgetting the new turbos fitted on saturday and hopefully i will get to 550 bhp at the fly without too much lag, im just hoping that it wont be too laggy....

Is there anyone over there that is running the same bhp as 550 ? and what mods you have to get there ?

I made 360rwkw on only 13psi at ADVAN. Engine has 88mm pistons, cams, oversize valves etc. TWO.06L on these forums has run a 10.3 with these turbo's also

Wrong turbos dude, two.06l ran a 10.3 on HKS 2530's...

      R32 GTR Limp Mode?

      By Nydt · Posted

      Hey y'all, I have a completely stock 1991 R32 GTR, yesterday I took my car out and went for about a thirty minute drive. It was fine on the way there but when returning home I think the car might have gone into a limp mode. I was cruising in 5th gear around 130km/h, the hicas light came on and there was a significant loss of power. About a minute later I hear a thump, the car starts driving normal again and is fine the rest of the drive back. This is the second time its happened, same as now it was fine on the trip there. On the way back it had the hicas light on but that time I would feel the power going in and out before hearing the same thump and it being fine.  I have no idea idea what causing this, but if anyone has any ideas it would be great as a start chasing the cause of this. Also I can provide more details if needed. Thank you

      Steps to DIY sanding car back ready for respray....

      By GTSBoy · Posted

      When sanding across a convex panel, you need to sand, as much as possible, at right angles to the curve. If the panel is compound convex curved (ie curved in both directions) then you are SOL and have to use "craftsmanship" to get it right.

      Duncan's V37.......race car?

      By MBS206 · Posted

      This sounds like me. And then why I leave shit that I had previously hobbled together broken. Lately I've changed strategies to "If I don't want to justify the money on decent stuff, I'm not going to justify hobbling it together". I'm still for DIY, but DIY it properly is more my thing. However, I am terrible on not setting up backups still... Which reminds me, I need to go backup some of my work VM machines... Oh, it's also why I've become a lover of building things into Docker Containers... Then I just need a machine that can run docker, and bam, that specific system is up and running, on the specific versions of everything I need for it to run (In the event a change in required software version breaks something else). Also, these days, my steep learning curves are spent with work related stuff, and on very varied projects, that my want to do other random projects like build a dashboard for my own car has dwindled away to "I just want the car running", which is my current PITA, as I'm getting the Landcruiser usable again, and it has just been non-stop the past 6 to 8 weeks of buying parts, and working on it. Oh, and tools that are meant to be fit for purpose... And they break, because 25 year old 4WD decides it's stronger... But by the time I have it ready to roll back out the drive way, nearly all the stuff in it will have been touched and serviced, so the damn thing better give me NO FREAKING ISSUES, for at least the next 50,000KMs! Just redone whole front of the motor, and resealed the up top stuff, replaced a bunch of things getting perished, new timing belt done, water pump, lower timing cover (Toyota diesel engine runs timing GEARS for the bottom half the motor, and a timing belt from halfway up to the top), new harmonic balancer, fix up the alternator, new thermostat, full swivel hub rebuild, new bearings and seals front and back, steering box rebuild, new battery, and today, it turns out a rear shock has let go, so four new shocks are about to go on order, and that will leave me with after the next run of work, to see if I need to order just a brake caliper re-seal, or if I'll need new pistons in them too. Oh, and I'll finish welding in the new floor sheet metal shortly too. Presently I just want it finished already... But once all the above is done, I still need to fully service diffs, gearbox, transfer, and motor. Then flush and bleed the clutch, and flush and bleed the brakes. But enough about our waffle, back to Duncan's heat problems... I think for Duncan he just gets a thermoswitch, and a manual switch to run some water misters. Thermo so it's only on above certain temps, and the manual switch so it can be turned off even if it is above certain temperatures. IE, switch on for "I'm now on track", then it doesn't need any "smart" computers that might try and do things wrong. And switch the thing off completely on the cool down lap, so when he stops in pits, there's not even a possibility of it dripping any water out to get him in trouble.
