Hi Guys,

Just checking if any 260RS owners have upgraded the front mount intercooler. I'm looking at buying the HKS R Type though wanted to be sure the one I'm looking at isn't too big and would fit okay with the front bar etc. Any help would be appreciated.

HKS R Type intercooler: http://www.rhdjapan.com/hks-type-r-interco...dard-size-29465

Part Num: 13001-AN007

Type: R

Core size / mm: 600×300.5×103

Why? Is yours damaged?

Nothing wrong with the one I have, I only just had it flushed and cleaned a couple weeks ago when I was getting some other mods installed... that was when I was told I needed a bigger fuel pump and injectors due to the car leaning out after 8000 revs on the dyno.....the stock system is getting replaced with the parts below. I figured since I've paid for the additional fuel capacity I could go for a few more ponies with a larger front mount.

HKS 600cc Top Fed Injector

HKS - Adjustable Fuel Pressure Regulator

HKS - Fuel Rail Upgrade kits

HKS Intercooler Piping Kit

Bosch 040 Fuel Pump

Pair of Z32 Air Flow Meters

The factory unit will not be a limiting factor.

Why do you need the fuel regulator and injector rail? . Bigger injectors will give you more flow and the factory reg and rail is up to the job.

What turbos are you using and what are you goals for the car?

I didn't know the factory reg was good enough, was just playing it safe seeing it wasn't that expensive. The fuel rail is just for cosmetics really...wanted to add some more colour to compliment the HKS adjustable cam gears and racing suction kit.

If you have a look at forced induction and particularly at the dyno section for GTR's you will see that the factory RB26 gear has a fair bit of headroom.

If cosmetics are important then that is an entirely different matter.

Thanks for the headsup, I tried searching for info but couldn't find much and figured for another $300 I'll know for sure it will work and the cosmetic aspect was an afterthought....... as it was it took me a while to find somewhere that said the stock fuel pump was only good for 155 lph, which when you do the sums with the injectors being 440cc and the pump at max 99% cycle it needs just under 157lph... hence the leaning at high revs on the dyno.

.44 * 6 * .99 = 2.61lpm / 156.816lph.

keep stock fuel rail and use nismo injectors. keep stock FPR, FMIC, dumps, airbox. look into nismo AFMS'

keep it looking stock. stock injectors/afms should do 280rwkw ish, what are you pushing? Base your mods off of an R33 GTR, and there are plenty of great threads of what to buy/not to buy, and how it can be done and keep it looking near standard. Forced induction is your best bet for non-stagea specific modding.

    • My thinking is that if the O2 sensor is shot then your entire above described experience is pure placebo.
    • Here is the mess that I made. That filler there was successful in filling dents in that area. But in the middle area. I can feel dents. And I've gone ocer it multiple times with filler. And the filler is no longer there because i accidently sanded it away. I've chased my tail on this job but this is something else lol. So I'm gonna attempt filler one more time and if it doesn't work I'll just high fill primer the door and see where the issues are because guidecoat is of no use atm.
    • Ok, so I think I sort of figured out where I went wrong. So I definitely overthinked it, and I over sanded, which is probably a large part of the problem. to fix it, I ended up tapping some spots that were likely to be high, made them low, filled them in, and I tackled small sections at a time, and it feels a lot better.    I think what confused me as well is you have the bare metal, and some spots darker and some are lighter, and when I run my finger across it, it' would feel like it's a low spot, but I think it's just a transition in different texture from metal to body filler.    When your finger's sliding on the body filler, and crosses over to the bare metal, going back and forth, it feels like it's a low spot. So I kept putting filler there and sanding, but I think it was just a transition in texture, nothing to do with the low or high spot. But the panel's feels a lot better, and I'm just going to end up priming it, and then I'll block it after with guide coat.   Ended up wasting just about all of my filler on this damn door lol  
    • -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.
    • Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go.
