GDay,

Just thought id ask all you gurus if a 600x300x105mm intercooler is a waste of time on an R33 GTR engine with forged internals, GT35 700hp turbo and upgraded everything else. Ive currently got a Hybrid 600x300x76mm cooler and i suspect this wont be enough to cope with about 320 - 350rwkw.

Ive got the opportunity to buy one for about $400 new so im just seeing what you guys think. Also, GCG in Sydney offer the 100mm intercoolers for $900 core only. Is this a bit steep? Any ideas where to get one for less than GCG's price?

Thanks,

Shaun.

it all comes down to the fundamentals of the design etc of the core as to wether an intercooler will work or not.

in saying that , it is a common misconception that bigger is better.

more often than not a greater thickness of the core is required when the face (surface area of the core) is small.

i am of the opinion that hybrid coolers suck , though im sure many upon many guys have them on cars producing 350 at the treads, which is their choice i geuss.

remember that just because a cooler "flows" 500cfm , doesnt mean it will work , the way a cooler should. i mean a peice of down pipe from ur gutter flows 500cfm but does it cool air.

if i was you , and judging by ur car and engine combo i wouldnt skimp in any area of its build up , go and buy a cooler and or a kit from www.are.com.au , i am biased towards that company as i have known the owner for a good 13-14 odd years now, and have seen numerous back to back tests and logging etc of various coolers, and also have one on my vl

in other words , 400$ for a new cooler , no way , go spend that 400 on alcohol and waste ur money on something u will enjoy :)

not sure why you went the Hybrid choice over the stock GTR cooler as they are good for the power figures you are aiming for anyway. The thing to remember is how well it cools the air passing through, not so much how much it can flow. Not 100% sure on this one, but if you go too big it creates more lag. Someone correct me if i am wrong.

Ill give the cheapo a miss, its too much of a risk.

yep good choice i have seen gtr's with reasonable gain from 250rwkw over the stock gtr cooler. a good 100mm cooler is the way to go not a cheapie. the jap branded ones are proven as well whihc cant hurt

meggala

I had an ARE bar and plate on my GTSt and was very impressed :(

Another recommendation for ARE!

    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful         
    • Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.
