Changing Intercoolers For 260rs

[CruisingFast]

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.
