Intercooler Selection

[Turbz_13]

Just wondering what would be a good intercooler and good size core for a GTR. brands im currently looking at are PWR, ARC, Blitz, Trust and Nismo(if i can find a place who sells them, and a price)

i know it will be a case of "what do you want to do with the car" forget that phrase, doesnt mean anything to me as i will still do what i want in the end!!!! just want peoples opinions on the brand, how well they work and whats a good sized core(thinkness wise)

thanks. James

if you dont plan to go over the 300-350kw then stock is fine

[Turbz_13]

am planning to change the turbo set up to either a nice sized single or a set of strong bolt on twins

Well that phrase should mean everything to you. Someone could suggest you get a massive thick trust drag item that will create lag when you're after response, or vise versa someone could suggest a smaller core when you're after 30 million rwkw's and it'll choke top end power. All of those intercoolers work briliantly for there intended purposes. As for you intended purpose, no one can tell you how well they work for that if no one knows...

whats the core thickness of the std gtr cooler?

[Turbz_13]

lets say im looking at 350kw atw. or running 20+psi boost....not that it really matters

[Yawn]

I would say the stock gtr cooler is good for up to 350wkw for street applications. The stocky is around 60-ish mm if im not mistaken.

For anything over that, most people go for something like 600x300x100.

what kinda power would a 70-75mm core see at the wheels, if the std core is only ~60mm..?

[Ronin 09]

a good 75mm cooler will see you at 400rwkw happily

[noone]

Whats the benefits in going over 75mm, I live in darwin its damn hot all the time.

Is a quality 100mm core going to restrict flow to the radiator much over a 75mm.

Is there going to be a major change in response. Have a crappy bent up fins 100mm at the moment so have no idea what stock was like

And looking for an upgrade running 2530's poncams powerfc usual mods and more for track than drag but keen to do a little of both

and the odd motorkhana just the usual stuff

Sorry if this is a bit of a hijack but seems I am in a similar situation

[rev210]

The standard GTR intercooler isn't shabby at all, pretty good core design and pretty much perfect end tanks.

I invested in a custom ARE built intercooler after changing to group a turbos and it certainly was significantly better than the stock unit with the bigger turbos. www.are.com.au

If you throw away the idea that the cars purpose has anything to do with intercooler selection then you lower your odds of getting the best.

as far as im aware, not sure if the 33 and 32 gtr cooler is the same but the 34gtr cooler is good for 500HP... so if the older style gtr coolers are the same it shud see u to 350rwkw easy. but seeing as its an old car now i wud prob go for a good 75mm cooler.

[Beer Baron]

Here is the deal. for what you want go for a core thickness between 70mm and 100mm. I have seen and sampled lots of coolers and the ones that stand above the rest are ARC and nismo. both can be had around $1500 or so. Me, I would go the ARC, but the nism one is top notch too. for you I would go 70mm for 350rwkw 100mm is overkill and will just starve your radiator of air more than anyting else.

[Turbz_13]

would the 70mm core still be suitable for a 350awkw GTR? i believe that to be around 400rwkw's??

[Turbz_13]

i know where to find the ARC stuff i just cant fond the NISMO stuff...can someone help there...cheers

[Yawn]

I agree Beer Baron and Ronin_09, as im using a 70mm ARC unit myself, with similar power output to what you want.

You can get the Nismo gear from Nengun or greenline etc., or a few traders from this forum can import one for you too.

my 32 GTR also has GRP A turbos and with the usual mods STD intercooler saw 320 ATKW with 20 PSI intake temps were fairly high and after a few runs was loosing power, and detonation was a real issue, there were a few options, cooler sprays or upgrading cooler.

I was going to go for a TRUST drag cooler or ARE cooler, the prices quoted did not fit my budget ($ 1800)!!

decided to get one of those cheap EBAY coolers ($380) 120MM thick and never lookled back after fitting up it made same power on 16PSI with minimal preassure drop. with 22 PSI made 460 RWHP and intake temps were no probs even after re-tuning on a summers day.

by running twin compressors it pushed the air through quite well (compared to big single) and only changed boost range by 400 revs. NO LAGG!!!!!!!!

water temps didnt move that much.

Cheers

Be aware that the thicker core you go the more you need to cut from your front bar to fit it.

a 70mm core is probably best for fitment and would suit what you want. ARC, Trust and HKS will do the job.

Nismo stuff will not be any better than ARC but about 30% more on the price tag. Both are direct fit items if you buy the correct one.

120mm thick is overkill for that application and you would see more response from your setup with a more reasonably sized core.

not all large upgrades require cutting the bar. mine, only a slight mod of bonnet latch and removal of one of the two horns.

Yep i agree a bit of overkill but as stated only cost $380,

and dont forget that a lot of the "better" branded items are now made in china, possibly even the same factory????
