I have just bought a new PWR intercooler to install on my R32 GTR. if I install the new intercooler, given that it has slightly higher volume (I think) than the standard GTR intercooler, would it be safe to drive without a retune, or would a retune be required straight away??

Thanks for your help

The difference will be negligible, I wouldn't worry about it.

What power are you chasing? The stock cooler seems to do a decent job.

If you are going to run it up on the dyno, back to back testing between the two cores would be nice to see.

Does the outlet look like the one below?

The top intercooler is for an R32 GTR from PWR. The bottom is an R32 GTR intercooler. One of these things is not like the other.

My question is this: Have the muppets at PWR fixed their drawings so their cooler actually fit now?

Mine sort of looks half way between the two shown in your picture. The PWR inlet/outlet doesn't seem to point down as much as the original GTR cooler, but hopefully the mounting brackets are located at slightly different angles to offset this.

Did you bother installing yours or did you just send it back?? If you mounted it, what did you have to modify to get it to fit properly?? And if installed ,did you need a re-tune??

What sort of power are you making out of your R32 GTR? If its highly modded and making big power then I would definitely want to get the tune updated to get the most out of the cooler change (assuming the standard one is a restriction).

If its only lightly modded then yeah dont worry about a retune, but I wouldnt worry about the cooler either. The standard gtr cooler is fine for big power 350kw etc.

Well it may fit. Just check it as best you can before you start ripping parts off the car.

I had mine fixed locally and installed. That invovled cutting off the inlet pipe & rewelding it in the correct position. As far as I can remember PWR "warranty" does not include freight and as they are in Queensland and I am not it would have taken weeks to get them to fix it. Ignoring the fact that I no longer had any confidence in their ability to get anything right.

Had a bunch of other things done at that time so the car got a retune anyway. You shouldnt need one.

Can you post a pic?

As an aside is there anyobne who does a decent 3" thick tube & fin intercooler for an R32?

+2 a mate has a PWR on his R33 GTR and his tuner at AVO thinks he will gain 40+kw by changing it out for another brand because it is a restriction in the system. 29psi was only seeing 370kw from twin HKS 2835

*Raises eyebrow*. Thats a REALLY poor result!

Not the first time this has appeared over the years.

stock GTR core for 400rwkw = win.

i had my cooler changed from std r34 GTR (60mm) to a 70mm ARC core and it made no difference at 350kw

the only real diference was that it would pull 350 for three consecutive runs, so it took a little longer for heatsoak to set it. but as far as power difference there was none.

a bigger/better cooler will only come into play when repeating runs on a dyno because it might stay cooler for longer?

just letting you know my experiences.

      Yeah based on old XRC5964S specs, it looks to be roughly GTX3576R sized? But this 5964S compressor will flow 90lb airflow somewhat similar to the compressors in both the GTX3584RS or G35-1050.. I fully expected the 0.64 rear A/R to choke up top - seems way too small from typical convention - but these are seemingly beneficial over the prior 0.82 results.. Be interesting to see if he comments on the EFR question in that thread - he mentioned in a prior video that BW EFR's were the "cats pajamas 10 years ago", but by the sounds of things all his kits have been using Xona for quite a while now.

      Yeah it’s still got the oem manual gearbox and clutch, only kinda mods are a blow off valve, coil overs, and a aftermarket intercooler. Also had it for about 2 months now with a lovely midnight purple paint on it.

      Yeeeppp, been following a lot of the testing on the latest Xona stuff and there are some mental results.  He also went over 1000hp @ 4 hubs on his Mainline with a XRE6364S (63mm) which was also well into the 20psi range before 4000rpm on a 2.5. Crazy stuff. Fwiw the XRE5964S is basically the modern equivalent of their old HTA3582 - would drive nicely enough on an RB25 or 26, but proven capable of a huge amount of power if you want to spicy with rpm tho even at sane boost levels will make stout numbers

      R33 GTST Axles

      The axels in my R33 seem tired, and have a bit of play in them. I cannot find any new of course, not interested in buying used, but I am looking to see if anyone can identify some cross compatible axles. In the states I have seen suggested for S chassis the J30 axles, however for the skyline (as best I can tell) the lengths are about an inch off (2.5cm) on both sides. R33 my measure L 22" R 24.5" GPT L 22.5" 24.25" J30 L 23.5" 25.5"  so shaft length is probably an inch wider. Not sure if someone has another still remanufactured option besides the J30. I figured worst case I can buy a pair tear them down and swap the center shaft. My other option was reaching out to GSP to see if they cannot piece together a set, since the axle stubs are still manufactured, I wouldn't think it be that hard to find a shaft or make a shaft work.
