Hks Fmic Or Stock Gtr Fmic? Which Is Better.

[R33GOD]

Had a mate looking at my car (r33gtr)cause he's never seen it before and he noticed i had a HKS cooler on it.

i knew it wasnt a stock item but yea... HKS!! we measured it and its about 100mm thick.

Now the question is will the HKS cooler out perform the stock gtr intercooler power wise? basically will i get more from my mods with this cooler than stock?

initially i am looking for a power goal of approx 280 rwk on about 16psi. will i get more power on the same boost or not with this fmic? lag? what are your thoughts.

here are my mods for anyone who asks:

-7's @16psi

wolf ecu

full exhaust

540cc injectors

nismo f/pump

apexi pods.

*injectors and wolf aren't in yet but will be soon. car currently on 12 psi*

thanks

The bigger and better HKS FMIC will allow you to run a higher boost than a stock IC.

The more boost, the more heat. The bigger the IC, the better the cooling.

A stock R33 GTR is good for abour 300kW's.

I read an artical in a ZOOM mag (I think) afew years back and they did a test for the standard GTR intercooler VS an aftermarket one VS a TRUST Triple core intercooler.

Some time bigger is not always the better but as what 2LV8ETRsaid... You have that option other wise there is no point in having a bigger intercooler.

stock GTR is good for a bit more than 300rwkw

Either way, if you have HKS one, all good and well. Doesnt offer much of a gain for your setup though IMO.

you can have a big cooler and it perform shit compared to a smaller one

its about the internal design, fins and so on.

Bigger doesn't not equal better necessarily.

If you saw the size of the coolers Nizpro use on the XR6 turbos for 400rwkw you wouldn't believe it - i didn't.

[R33GOD]

so is the stocker better for my power goal?

[R31Nismoid]

its not worth changing put it that way even if there way a gain...

because do check properly you'd need to do back to back testing etc to find out exactly, every setup is different

I have 330ish rwkw on a stocker no probs. I think your limiting factor will be the 540cc injectors, at my power I am hitting 90 percent duty cycle at close to redline with 700cc.

Someone may correct me but I would sell yours and get bigger ones so you always have some safety net, you don't want to be running 100 duty cycle

stock 440's with a FPR and a minor increase flow 300rwkw. Ferni has done it before.

I see 90% duty @ 280rwkw/15psi on factory injectors at the moment as a max.

550's flow enough for 340-360rwkw without a drama at all. I've got a set sitting here waiting to go into mine.

700's should be good for near on 400rwkw from memory if not more

If your @ 90% with 700's I think you have a fuel pump on the way out, or perhaps a slight blockage somewhere/bent lines etc.

[R33GTRKid]

hmm new pump, new afr, so will check again tonight

Are R34 GTR FMIC different to R33 GTR FMIC?

People are running 400RWKW with stock R34 GTR FMIC
