New Intercooler

[Shadex]

Hey all, Im looking at putting a new cooler in my car.. Cause mine is looking pretty shot..

Im looking at putting a 600x300x100mm in my car.. the turbo will be running around 16psi when its all back together..

Its a R33, Minor mods... Power fc, Cams gears, 3" straight pipes with a varex, And a FMIC thats not looking to healthy

My only problem is i have heard.. with a bigger cooler you loose boost pressure if your running low boost, but my issue is.. what do you call low boost?

And is this just a myth?

[SDEWY5]

dunno wat low boost is considered maybe 10-12psi? but id imagine u would struggle to notice a difference

[Shadex]

Yeah, Im just wondering if a 75mm is gonna be more beneficial?

I would personally go a 76mm cooler core, 100mm is way to thick. Also if your have a real thick intercooler, its harder from air to pass through and your radiator will recieve less air and then may have overheating problems. Save your money and get a 76mm core, you will probably notice a bit of lag with the 100mm core, because there is more area to fill, it takes longer.

I see, I was looking for something in between, say like.. 85mm or something but i wasn't haven't much luck finding anything..

Intercooler core design is the bigger issue - whether it is a tube and fine or bar n plate. Do a search for the differences.

When i was upgrading mine, i looked up and found that the tube and fin design is more effecient at cooling the charged air - however something to do with how it flows through the tank which affects radiator effeciency. 76 or 85mm wouldnt really make that much of a difference.

IMHO - I think that a 76mm tube n fin design would be more effecient then a 85/86mm bar n plate. Im using a tube n fin 85mm HDI fmic and I dont have any overheating issues at all.

Best to do your research before you think of buying anything. Good luck!

I sure hope your not running 16psi on the standard Series 1 turbo...BANG

A RB25 standard turbo is good for 18psi or so?

[cmoney]

Nope....tends to go bang with anything over 14-15psi being constantly pushed through it. Hi-flowed with a steel turbine wheel sure, but ceramic will simply discintegrate & part ways with the turbine housing & disappear into your exhaust somewhere....

mine went bang at 12psi drifting! do NOT push it man

[Shadex]

Hmmm, Cause ive been running it on 13 for awhile.. Boostworx told me there good up to 18psi :S

Back to topic, get a Greddy, HKS, ARC, Blitz, Nismo, etc....76mm cooler.

If you are on a budget the cooling pro ones from just jap also do the job fine.

If you are not running at least 20PSI or higher then there is not point and a waste of money to buy a 100mm cooler.

As a comparison, many GTR owners out there are pushing 350AWKW with the stock cooler no probs!!!

Why would your car need a 100mm if its pushing no where near that?

Check out the SAU sponsers as they look after the members with good pricing.
