Hello

It has been a while since I posted on here, over a year. I have read the posts but still need some help. Please help. I live in Japan, American, so not Australia, but dont mind buying parts from Australian stores.

I have a new 1992 R32 GTS-T. This time its a manual. My first car died. I am taking parts off of it. I am going to take the RB25 turbo with the HKS aculator and put it onto the new car.

SO far the car has a 3 inch cat back exhaust, split front pipe, stock cat, Apexi air intake and that is all. I am going to add the RB25 turbo as I mentioned. Should I keep the HKS aculator on it or put the RB20 one on?

I am getting a inter cooler also. Will used ones be fine such as ones from Blitz or Arc or used GTR ones? I can find cheap used inter-coolers here for about 100 dollars.

My goal is 300 hp but now I am aiming for 250 hp to start. Should I replace the fuel pump too since I am adding the turbo and inter cooler? If so than I will buy a after market one rated higher so when I start the big mods I will have it.

What else should I add now?

Are the Emanges' still a good option　for tuning later?

Help please

What is the HKS actuator set to? If you still have a stock ECU, it will probably go into Rich & Retard mode (R&R) if it's set to 12psi or higher.

Change pump for peace of mind, it's what 18 years old now, no guarantee it will take kindly to the extra power.

Since you are aiming for 250hp, the stock intercooler will do, but at 300hp, you will need a better one, used intercoolers should be fine as long as the fins aren't damaged and you give it a good cleanout. At 300hp even the R34 stock sidemount is a decent upgrade to support that power, but no more.

The ECU is stock. I am not sure what it is set to. The adjusting screw is at the opposite end 80% from the starting point.

So should I switch to the RB 20 aculator?

How do you clean out a inter cooler?

      New to R32 ownership

      By luke gtr · Posted

      Unfortunately,  it feels like it's been on the decline for nearly a decade. Especially as wallet racing became popular with them(biggest wallet can pay off a car that wins). It seems like a different mindset kf ownership these days. But, hopefully people like yourself keep some of the skyline scene alive.

      Realistic Injector/kW Limits on E50 & E85

      By Dose Pipe Sutututu · Posted

      A bit of data is always good, beats the Facebook experts with their opinions Although the kWs aren't anywhere near what you are after, it should give you a good indication. I have Bosch 1480cc injectors, often called 1650cc (only when run at 4bar). I run mine at 3bar base so I don't thrash the fuel system. Up top, making 437kW with boost dropping, injector duty is at 69% on E80 (might have had some residual 98RON in there)

      Realistic Injector/kW Limits on E50 & E85

      By TurboTapin · Posted

      I have some downtime due to winter, and just wrapped up converting the car over to flex fuel. We don't get E85 at the pump over here in Canada, but I will be running Ignite E90 Race gas. I'll be mixing it with 99-100 RON pump gas and shoot for 50% ethanol content, up to possibly 85% content if there's any noticeable gains. Here's the question. Most I'll ever want to hit is ~600rwkW. I've currently running 1200cc injectors and want to keep them under 90% duty cycle. As per some online injector calculators, I should be good with 1200's well past 600rwkw on E85. As per other calculators, I'll need 1600-2000cc's. The variety is rather amusing.  With you Australians having E85 at the pump, what realistic duty cycles are you seeing in those kW ranges on E50 & E85 on your injectors? Thanks,

      No issues here with my PRP gears in an OEM pump housing. I did confirm all housing clearances were to spec prior though. Cheers.

      Water leaking into the rear trunk

      By 32.det · Posted

      Thread is a bit old but figured id give my input anyway just incase. Have had lots of water problems in my R32 and was getting sick of wet tools in the boot and water filling up half my taillights. I ended up finding that whenever my car had been repainted they didn't reseal the taillights to the body of the car so water was just flowing straight into the boot, this is amplified by all the water around the bootlid being directed down to the taillights so would get pretty wet whenever I washed the car or it rained. You could probably use silicone to seal them to the body but I think from factory they use a roll of automotive grade butyl rubber. Hopefully this helps you if that ends up being how the water is getting in on your car!
