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.

      Possible swap on R34 RB20DE NEO?

      By GTSBoy · Posted

      If the RB29 box in the car is a push clutch, then yes, you will need to deal with the pull clutch on the turbo box. You either buy a pull clutch and don't use the old one, or you do the things needed to convert the turbo box's clutch arrangement over to push. Which is a bit of a f**karound. "Making" a custom tailshaft is the easy part. But you will need to source the front clip yoke - the bit that goes into the output of the gearbox. These are not as easy to find. They are out there, but they don't grow on trees the way that they used to.

      Turn signal wiring question

      By GTSBoy · Posted

      Indicator bulbs are way too bright to use as a "corner marker" (we call them parking lights too). Sure. Go ahead and do it. But realise that you wil need to come up with all your own wiring to do it, as no-one will have a standard howto worked out for Skylines. It's just a matter of abandoning everything that Nissan have done and starting from scratch. You'd probably be better off retrofitting tailght/brakelight globe bases into the front indicator housings and using the taillight circuit for your corner marker and the brake light as the indicator. You'd need to work out how to kill the marker circuit while the indicator is flashing, otherwise it won't flash on-off, just bright-less bright.

      Possible swap on R34 RB20DE NEO?

      By Kapr · Posted

      Hi. A little bit of an update. It maybe(hope not) looks like i would need a new tranny(it would be "maybe" a cheaper or better option anyway) So i need some info. I know i need a different propshaft(i can make custom one) LSD is not a problem cuz the engine will be still(for now) N/A RB20. So if i buy RB25DET NEO tranny...is there something else i need? I read something about push/pull type but i do not know if i need to "change" something or i can just plug n play onto my engine a go? Thanks for the advice

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..
