Types of I/C off GTRS

[judd]

Ok last night i meet a guy with a Stock R32 GTR also, he checked out my car and said nice I/C. I thought and still think its a std I/C

BUT.....he is convinced mine is a 97 V-spec Cooler. Because it doesnt have the lines going through it. Can any one tell the difference, which comes to my next concern, someone told me i have a Tight rear LSD because at low speeds while turning it is jumpy. others say it is std.

Judd - I'm not sure if you can tell that if your car is jumpy it is due to the LSD. but then again I'm not an expert..

Also as far as I know I didn't think theres any difference at all between the regular GTR and Vspec intercoolers. I have a HyperRev that shows all the differences in the models between Series 1,2 and 3 GTR's and the Vspecs and it doesn't mention anything about coolers....

[judd]

well he said that? i dunno maybe 97 GTR cooler??

wat is diff between R32 and R33 i/c

[400HP]

yeh well mine is a 97 GTR and i'm quite sure the cooler is the same as the other 33 GTR's.... I'm not sure the diff between the 32 and 33 coolers though... but I think their the same size... hey how did u go last nite?

Hi Guys from what I can tell;

* the R33 GTR I/C has one more row of tubes than an R32 GTR I/C

* the tubes themselves are slightly bigger in diameter than an R32 GTR I/C

* there are visible weld joins on the tubes, that are either not there on an R32 GTR I/C or can't easily be seen.

I have not had an R32 and an R33 I/C together in the one place at the one time. It has been a couple of years since we had the R32 GTR I/C and I have just got an R33 GTR I/C and these are the things I remember as looking different.

What I can tell you for certain is, on the flow bench, the R33 GTR I/C flows about 5 to 8% more air at 500 bhp with 1.5 psi resistance. Turning that around, it flows the same amount of air with around 1 psi less resistance.

Hope that adds to the information bank.

So what ya saying is the R33 GTR cooler is better....

NOTE: The only differences inbetween a GTR & GTR V Spec is its suspension..

(Im not talking about kits, badges, dump pipe. Im talking about major differences....)

Sydneykid,

Your car says R32 GTST RB31DET have you got a bored out 3litre block in your R32, must be a bit of a beast!!

and nismogtsx:

The R33 keeps the RB26DETT engine from the R32 GT-R. The power is still the same with an official 280hp (206kw) at 6800rpm, although inofficially it is ass-umed to be around 302hp. Increased peak turbo-boost of 0.84bar, an improved intercooler and changed computer control parameters make for a higher torque of 375Nm (271 lb-ft) at 4400rpm. As usual, power is deployed via the 5-speed Getrag gearbox and ATTESA-ETS to all four wheels.(from http://www.infinitig35.net/R33/GTR/index.php)

so sydneykid is right!!
