Help Needed Installing Grex Oil Cooler R32 Gtr


Recommended Posts

Guys, as titled, I need some assistance with a Grex oil cooler. The model I ordered should fit into the right inner fender. I guess that means the drivers side right? But all the pictures in the japanese instruction book refer to the passenger side? WTF is going on?? I am trying to fit the cooler in front of the factory BOV but I have never seen a cooler mounted there with the BOV's still installed. I wish I could read japanese. Can anyone shed some light?

Thanks for that. Grex make a number of different kits. They all have various length hoses depending on the coolers location. Has anyone fitted the grex cooler infront of the factory BOV's?

I'm not sure if its going to fit and my instructions are for the wrong location :happy:

I got a HKS oil cooler it goes on the passenger side , the lines run under the motor

I highly doubt you can fit it (any cooler) in front of the BOVs. mine is in the passenger side duct. mine is a grex kit also. the big one. and it just barely fits in the passenger side duct.

ive spoken with the guys at meridian motorsport about an oil cooler for my gtr and they say they have never fitted a cooler to the drivers side. they have always put them on the passenger side

i have a large one.

mines mounted horizontal (laid flat) here....

shot is from under. and its more over to the passenger side. left part is front lip

max temp today was 85c which was driving for a long time with a fair bit of hard driving (i went bush)

you know the inner fender probably refers to the area right in front of where the RHS front wheel arch is...

i.e the position where the GTSt ventilation slats for the SMIC are cut into the inner plastic guard on the passenger side, but on the driver's side...

so the cooler sits not against the front bar, but behind the BOVs nearer to the wheel well?

does that make sense??

What size cooler and was it a Trust / grex one? Do you have pics? The instuctions I got with the cooler shows installing it in left inner fender. USELESS!

I must be the only one with a 32 GTR who installed my oil cooler in front of BOVS....special. It can be done.

19 row oil cooler kit from UAS, earls fittings etc. Tight fit near one of the BOVS but the reason mine fitted was that I had previously removed the BOV piping. Also made brackets from aluminum to mount cooler.

That's great. Thanks for the pictures.

I purchased the Trust / Grex unit because it's of high quality and I prefered a vehicle specific kit rather than making brackets and having hoses made up for a universal kit. That's why I paid the extra money for it. But it seems unlikely this kit can fit in the intended location without changing BOV's or stuffing around. Not happy. I was assured this unit will fit without any modifications from the supplier, whitch I have in writing.

Some pics of my setup:

    • Done few measures to work out how I'm going to fit the Thermotec Exhaust Jackets to my headers, the kit comes with 8 steel zip ties and 80 clips, enough sleeve to cover each primary 600mm(24"), thus having a clip every 75mm. I test fit one of the primaries, the sleeve covers my 1 7/8 primaries well, and when the clips are on (I didnt use the clips, I used some small stationary fold back clips), there isn't any gaps which is nice. Looks the goods so far. Just need time to do final fit up, and then take it for the typical "smokey drive" until the sleeves "cook off" the manufacturing residue like the normal heat wrap smoke show. The hard part is covering the No1 primary on the 4:1 headers that obviously is bolted to the car and ducks behind the other primaries, I assume I'll be laying on my back playing "elastic man" with my arms Also purchased a few electrical glands to run the RaceTCS wiring thru my firewall as I cannot see a neat and easy way to jam the cables through any existing "holes", 3 x 16mm glands to suit 5-10mm cable, the CAT6 cable is 5.5mm and the 2 ten cores are just on 9.5mm, tight enough to keep the moisture and engine bay fumes out. They will hopefully fit on the firewall on the passenger side without to much fuss, I've had a quick look, but there will be alot more looking before the 16mm holesaw gets to to play. I'm still waiting on a rough quote from Autotech for the actual termination into the PCM and ABS modules, whilst the actual job isn't rocket science I would prefer to "pay cash" to someone with more wiring skills and proper tools for the job than me. My wiring skills stop at buying the wiring, the Deutsch connectors, drilling the holes in the firewall, and fitting the glands, any more could result in fire, or possibly bay windows in the block. Why am I drill holes, I need to feed in 1 x CAT6 from the ABS module into the cabin, and 2 x 10 core, 1 x 10 core of 8 injector out, and 2 earths, and 1 for 8 injector  in for the injector interceptor wiring and a power. I will be heading into Autotech to get approval for my cunning plan. So many coloured wires and tapping into to ABS and PCM makes Mark's head hurt......... I pay cash now..

    • Now with a fresh alignment, a lot less toe in at the rear now as it's no longer needed (subframe offset by 10mm upwards). Front toe touched up and I think I'm some what ready for All Jap Day, which might end up being cancelled due to the rain.
    • 4D table allows you to say have the slider at 0%, 25%, 60%, 80% ethanol as an example, giving you multiple maps if you will. Also removes the need to do arithmetic when you're tuning, no need to go ahh I need to add 11 to my base table cell of 8 to give me 19. I "think" it makes tuning a bit easier, however still yields exactly the same results as using the conventional compensation tables as you and I are both well versed on.
    • We're setting the backlash. "Shouldn't" need to change it as the same front centre, crown wheel and pinion are going back in that came out of it but we will see.
