Squizz. Cool, I'll organise a drive in the next few weeks. I'm going to Melbourne this weekend for the "Show Off" series. I'm having car show withdrawalls since the last decent show I was at was the Auto Salon final battle.

Muz. What is the difference between the HKS cooler and the Trust cooler ?

rb26DETT. Is the temperature going outside specificatiion or is it just getting hot ? What deg would you say its getting to ?

I have been having a good look at different kits and was just about to ask anyone if they had used the HKS oil cooler kit. The particular HKS kit for the 33 GTR is very large, much larger than the trust kit (although trust has a few different setups), its a 16 row cooler approx dimension off the top of my head were 220ishx200ishx40ish. But by the sound of it, it sat inside the wheel arch, not sure how I feel on that. The wheel arch option might be alright with a 400R front bar but I am not sure there would be enough air flow through that area with a standard GTR bar. mmmmmm.

There was no specification. Whatever people say like it will reduce blah blah blah by how many degrees does not matter. The RB26 makes a lot of heat, don't know why either...maybe it's cos of the second turbo??

Anyway I found that with the cooler, it just reduced cruising temperatures and gave me probably another 5 to 10 mins hard driving in the mountain. Temp. gauge on the GTR console was reading halfway (I always back off when it gets there), so I'm assuming around 95 to 100 degrees?

Best would be to fit it and then go for a strap...makes a difference, but not much.

If you could, just go for the biggest possible oil cooler, more volume of oil plus larger surface area to cool the oil. IMO, i think the ARC's oil cooler would have to be one of the best, too dam expensive though.

GTRman, I can't answer what the difference is as I didn't look at the Trust item. I have a Nismo front bar and have mounted the cooler in front of the right front wheel behind the duct opening in the bar. rb26DETT is probably correct in saying that you need the biggest cooler you can get(within reason) and have plenty of air ducted to it. Remember the GTT is only a single turbo so the under bonnet temps will definitely be lower but the oil cooler will definitely reduce your engine oil temps

You really need to fit the oil cooler in clear air to get the full effect. Fitting it behind another cooler will only ensure that it gets hot air from in front and radiated heat from the radiator behind.

Ok. Well I'll fit the cooler (between the intercooler and radiator) and see how it goes.

BTW I have the owners manual and it says the safe region for the oil is to the line above the centre line.

Yep and so is the HKS kit.

Simple logic tells me that if the vehicle is moving, then the swept hot air from the intercooler is being directed onto the fins of the oil cooler which not only is having to deal with the oil being hot, is now having to deal with a higher ambient temperature passing over its' fins which in turn then passes the hotter air onto the radiator which by now is really struggling. Probably got an A/C condenser in there somewhere as well. Probably compounding the temp rise all the time.

Just my thoughts is all.

the trust kit is made to be mounted there

For the life of me I can't understand why you guy's want to run Jap oil coolers. Gibson never did,,he ran Sereks or the like with direct ducting. The jap one are way to thin and the oil passes through them way to fast.

      RB26DETT Sketchy boost mod?

      Or do we think it was installed to give 1 bar of boost max, all day, everyday?

      So could it be assumed it has been installed intentionally with potentially a power FC boost controller kit?

      What should I do next to hold the head on

      By Gareth87 · Posted

      Had my rig on Matt's dyno at PITS the other day. After a few years between tunes I added a few sensors and swapped intercoolers. Result. 553hp at 26psi. Not bad for an FJ20 that was built in 2007. The problem.. It filled the overflow bottle on hard runs which leads me to believe the head gasket isn't sealing. I have a coolant pressure sensor which was reading cap pressure at 22psi and occasionally overrunning to 23/24 psi on deceleration after a pull. It was not spiking. It has arp2000 head studs and a cometic gasket. As its been 18 years in service, I pulled the engine out and head off. Everything looks good but we obviously have an issue. Where I'm at.. Years ago I had the same issue, I checked the stud tension and they were all over the place. Some at 60 to 70 and some up near 90. I nipped them all to 100ft lbs and this stopped the water push until now. I believe this compromised the gasket back then. What do I do? 2 options are..  1) I bought arp 625+s, which I could put in with a new gasket. Thinking Kameari this time, reassemble and try again. 2) strip the block, get fire rings machined in with copper gasket and try that. I do not want to push it more than 28 to 30psi. I think the turbo will be out by then anyway. (G30-770). My other concern is the long term ability of a copper head gasket. Are they streetable for years? I feel like a new gasket with the new studs will probably suffice, but I don't know. Any thoughts welcome and advice on copper gaskets and fire rings. Thanks!

      Chris' Toyota Mark ii JZX110

      I'm a fan of the JZX110, and the Aristo. Big cruiser cars, and with the factory cars, super comfortable and feel like you're driving an armchair! And the JZ motors are a pretty nice engine too, especially with some basic mods.   The import process, and the need to be able to trust people, and the fact there's so many scammers around is what ever puts me off wanting to go through that ordeal!
