Would this front mount i/c be o.k.?

[Nu2skylines]

I've researched different sizes and brands of front mounts but I still have a question.

Someone has a trust 410mm x 260mm x 70mm front mount with 60mm endtanks. Would this intercooler be large enough for my R32gts4? Modifications are only turbo timer and hks exhaust.

[Gradenko]

Whats your power goal? If anything, it may be too large.

[Roy]

If anything, it may be too large.

Too large??? Here come the differences in opinion:D

[MADGT4]

Man i got a GTS4 and i'm gettin a 600x300x80 that thing is tiny man go for something a smidge bigger i mean i only got Zorst, Dual Boost controler and thats it.

In this case bigger is usually better but not too big don't want too much of a pressure drop etc.

[Steve]

In a word - yes

It would probably be fine even if you intend going a larger turbo as well, something like a HKS2530.

the best sized cooler is one that is optimum for your hp goals - too big and you will get extra lag and a more sluggish throttle response.

going by the aftermarket coolers I have seen (not too many, so please dont take my words for gospel) a 'good' cooler of the dimensions you quote should be good for over 400bhp.

to quote http://www.horsepowerinabox.com/make_model...skyline_r33.asp

Note this isnt a Jap brand name cooler that they are talking about, but a local product. I have no reason to believe that a japanese product is going to be inferior:)

This intercooler uses an 18”x12” high by 3.5” thick bar and plate intercooler core, smooth aluminium tanks with 60mm inlet/outlet and centre mounting points make for quick easy fitment with minimal front bar trimming. The core itself is rated at optimum 580 horsepower with 1.5 PSI pressure drop at that level.  We have made up to 630 horsepower through these cores but with nearly 2.25 PSI pressure drop.  This cooler was featured in a Zoom magazine technical article where it proved to reduce air intake temps by nearly 25 degrees over the standard intercooler during testing where the car was run at 11 PSI for 15 seconds at 5000 RPM.  The standard intercooler had a pressure drop of up to 8 PSI at 7000RPM whereas this one had a mere 1 PSI drop.  

A bit of that is probably sales pitch, but I dont think it would be far enough away from the truth that it wouldnt be reasonable to expect good performance at up to 400 or 450bhp

my 0.02 anyways

Gradenko: Not too much since I'm just looking to learn how to work on the rb motors. I've already put a turbo timer and a hks exhaust on it. Looking for an intercooler and boost controller (probably greddy profec B). Changing the plugs soon but so many different opinions and I don't know what's in there right now. I checked the NGK catalog and it says 5 but then some people say 6. I don't know if to go platinum or iridium, heat range 5 or 6? I've searched many threads but still indecisive.

Madgt4: Wow, that does sound pretty large? Are you going to have too much pressure loss in that i/c? I guess that depends how efficient it is.

Steve: No, I'm not upgrading any turbos or anything. I'll probably be purchasing hks2530's from what I have read later for the R33gtr or R34gtr.

Thanks for all the advice, I'm just looking to upgrade a little and learn on this car before I purchase my R33gtr or R34gtr next year.

Anymore advice would be great. And yes, I haven't been posting much because I've been searching and reading through everything first.

That cooler will be just fine dude.

Your standard cooler will be fine for around 12 psi through the standard turbo.

Put it this way.

The standard size that MOST companies make there intercoolers is 600 x 300 x 70.

A standard GTR cooler is something like 600 x 270 x 70 (I think).

If TRUST has decided to make a cooler that is slightly smaller for a car that is more lightly tuned, I would buy it.

Actually, I would buy anything TRUST makes if I could..

send a PM to "rev210" asking about your intercooler....

He has run a 12 second pass in his R33 GTST with the standard cooler which is not that better than the R32's..

He'll set you straight.

I was under the impression that he never got his 12, just low 13s??

BOOSTD managed a 12 with stock turbo, but he had a cooler.

[TTT]

my mistake.

still.

decent number with a standard intercooler.

My point was that rev210 is one of the guys int he thinking that the larger the intercooler is not really a better thing.

It has to be matched to your turbo and so on.

So this particular intercooler 410 x 260 x 70 made by a company like TRUST will be mroe than enough for a R32 GTS4 with a cat back exhaust as the only mod.

Actually, that intercooler would be more than enough for anything the standard turbo will be able to handle.

[Nu2skylines]

Thanks guys. I actually forget to say that it has a hks highflow filter but it was on there when I purchased it, not that it matters.

As I said, I just plan on putting a greddy profec b and the i/c before I get my gtr.

By the way, any suggestions on my plug situation. I'm fixing to order them. And yes, I have searched but still with so many opinions. What do you guys run on your gts'?

[Steve]

With cooler and exhaust, boost etc I was running NGK BCPR6ES (copper) gapped to 0.08mm - worked much better than the stock ones which are a heat range warmer and gapped at 1.1mm.

[TTT]

I've got 1 range hotter than steve and gapped the same.

the mods I have are..

RB25 turbo

3 inch turbo back exhaust

trust PANEL filter in standard box

ARC Standard intercooler replacement (fits in factory spot)

13psi

works without any probs..

[Nu2skylines]

Thanks. I was checking those out and noticed that the BCPR6ES plugs were gapped at 0.08mm and the BCPR6ES-11 were gapped at 1.1mm (0.044"). I guess I'll be ordering a box today since I can get those for only about $3 plus shipping of course. I've checked local auto shops and they want $12-15 per plug.

[TTT]

$12-$15 per plug for copper plugs?

sweet jebus..

they are like $3 - $6 each around here..

[Nu2skylines]

Seriously, I'll be ordering over the internet. So GTST, you went with "7's" since you went colder? I know NGK does it differently than others and the cold-hot is opposite. Higher number, colder the plug from NGK. I hate that when I'm ordering for my gsr because I normally get 2 steps colder.

[TTT]

You're confusing me now..hahahaha

I thought that the higher the number was the hotter range..

anyway..

I can't remember..

but it is the standard heat range for the skyline.

just gapped to 0.8

[Nu2skylines]

Me too but I always have the ngk website bookmarked:

NGK heat range

It's with the other brands that they do the opposite of NGK. I actually think NGK just does the opposite of everyone else just to confuse people.

Also you forget revs car was a freak and hes been the only one able to get such a low time with stock stuff!!

[Sydneykid]

Hi guys, courtesy of Mr Donnon, we run NGK BCPR7ES-11 Copper. Really expansive, like $3 each.

[Guest INASNT]

but u have to replace copper plugs more often that iridium or platinum plugs???
