Difference In Gtr Intercooler Sizes

[stiffler]

I have an r32 gtr with what looks like a standard gtr cooler that has an alloy look in appearance. From my understanding the 32's and 33's came out with black coolers but this one may have been cleaned and doesnt have a temp sensor hole like the 34's have. I recently bought a 34 gtr cooler to put on my car and i noticed it seemed a touch smaller so i whipped out the measuring tape and this is what i found.

r32gtr = 600x290

r34gtr = 600x265

On the forums ppl said that the 34 cooler are a little bit better then the 32 and 33 coolers but i havent found anywhere that it says that the 34 is a touch smaller. The 34 basically has one cooling passage less and fins either side of it which results in the smaller size.

Can someone confirm the sizes for me please?

The two I've had in my hands to compare:

R32 GTR intercooler, 25 row and around 290mm tall (calsonic sticker)

R33 GTR intercooler, 23 row and about 270mm tall (no noticeable markings)

Other sizes & construction were identical

thanks for your reply. I guess no one knows why the r34 gtr cooler flow better, or apparently flow better

It's probably bullshit anyway, unless someone sets up a testing bench and back to backs all three you really can't say either way.
