Hey everybody, does anyone know the measurements to a stock radiator in a R34 GTT. I'm looking at upgrading to a PWR product, If anyone has already done this what were the benefits you saw, how long did it take and how much did it cost.

Cheers

Two bolts for shroud, two bolts for radiator top supports... bottom hose, flush coolant, remove top hose, remove radiator and replace.

Took me about 20 minutes to remove the old one and replace. Looks fat and will give you so much better cooling potential. Very worthwhile upgrade in my opinion.... next is silicone hoses and better clamps.

Also the radiator has nice strong alloy hose outlets, as opposed to crappy plastic ones that break in your hoses.

Thanks mate spoke to a guy called jamie at Natrad radiators in midvale said its top of the line in radiators, but also mentioned that if your at the lights it can creep up over half way on the thermostat, but as soon as you get going again it flys back down, do you think this is a huge problem or is it cause that the radiator is made out of aluminium. Also I'm gettin a Garrett GT30 turbo upgrade, bigger injectors and a airflow meter installed soon do you think that having the radiator put in will help keep everything cooler or be the same with a stock.

It will probably be the same as stock or better. Ebay aluminum radiators work a treat :) no problems with them so for a while.

Depends what you're using them for.

I had an ebay ally radiator and it used to heatsoak something horrid after half an hour on the hwy and temps would just steadily increase. It also couldn't handle a decent burnout on a 40deg day, would spit coolant everywhere.

Turfed it in favour of a stock 32GTR radiator and the difference was huge. Temps well under control, a good 2.5min burnout on a 40deg day would see no more than 105deg.

Also a FYI, temps WILL increase when stationary UNTIL hot enough to engage the clutch on the engine fan. If it gets TOO hot, the A/C fan will kick in.

Another FYI, you won't notice the needle on your factory temp gauge move until the temps are over 100deg.

Nah not yet mate was gonna be the last of my engine mods, previous mods were tomei typeB camshafts, bigger rear housing on turbo, on top of other previous mods now running 324HP so pretty decent for everday car will post up when done and if increase in hp or better performance overall. Spoke to a guy a Natrad radiators a few times, so have a few other people on this site says there the shit, so i will have it done eventually.

Are you having overheating problems at the moment? Do you have an oil cooler?

I am running the stock radiator and clutch fan with 400rwhp and no overheating issues.. Got a bit hot on the AHG pan with then it was understandable considering the ambient temps.

An oil cooler would be of a lot greater assistance than going for a replacement radiator - unless it is faulty.

Good point on the oil cooler. I'm not sure about the OP but my radiator is visually rusted inside so I'll conduct another flush and replacement. I'm also considering a cross-flow radiator. Anyone have any experience with the PWR crossflow (or any other company)?

In all honesty mate spend your money on something else for your car.

My 32 is running a standard rad and after 5-6 laps of beating the piss out of it around barbs it is still only around about 115 deg.

IMO dont replace it unless it's broken

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      Look for broken wire or bad connector at the motor. Might not be it, but is worth starting there, as it is easy.

      R32 GT-R: 4WD Light Turns On After Bumps – Code 19 (ETS Motor) But No Issues Found

      By Bireley_32 · Posted

      Hi everyone, I’m having an issue with my R32 GT-R. Sometimes, when the car goes over a bump or experiences some vibration, the 4WD warning light comes on the dashboard. When I check the code from the control unit in the trunk, it shows Code 19 – ETS Motor. However, everything seems to be working fine — if I turn off the engine and restart the car, the light goes away and everything functions normally. Has anyone experienced this before? Where should I start troubleshooting this issue? Thanks in advance!

      I'm back from the dyno - again! I went looking for someone who knew LS's and had a roller dyno, to see how it shaped up compared to everything else and confirm the powerband really is peaking where Mr Mamo says it should. TLDR: The dyno result I got this time definitely had the shape of how it feels on the road and finally 'makes sense'. Also we had a bit more time to play with timing on the dyno, it turns out the common practice in LS is to lower the timing around peak torque and restore it to max after. So given a car was on the dyno and mostly dialled in already, it was time for tweaking. Luis at APS is definitely knowledgable when it came to this and had overlays ready to go and was happy to share. If you map out your cylinder airmass you start seeing graphs that look a LOT like the engine's torque curve. The good thing also is if you map out your timing curve when you're avoiding knock... this curve very much looks like the inverse of the airmass curve. The result? Well it's another 10.7kw/14hp kw from where I drove it in at. Pretty much everywhere, too. As to how much this car actually makes in Hub Dyno numbers, American Dyno numbers, or Mainline dyno numbers, I say I don't know and it's gone up ~25kw since I started tinkering lol. It IS interesting how the shorter ratio gears I have aren't scaled right on this dyno - 6840RPM is 199KMH, not 175KMH. I have also seen other printouts here with cars with less mods at much higher "kmh" for their RPM due Commodores having 3.45's or longer (!) rear diff ratios maxing out 4th gear which is the 1:1 gear on the T56. Does this matter? No, not really. The real answer is go to the strip and see what it traps, but: I guess I should have gone last Sunday...
