Hi Guys,

As stated I need an oil cooler for my R34 GTT.

It's recently modified and running close to max temp. during winter. This being the case I'm going to need an oil cooler before summer.

I don't want to spend a shit load of money if I can avoid it, that being said I'm looking for a reasonably good quality unit.

I don't see the need to purchase an expensive brand. I know there are a lot of cheaper ones out of china these days, but what's the quality like.

Interested in any thoughts people may have.

Thanks

Paul

On my old R33, I had one from "performance-wise" unsure if he trades anymore, but he had a few threads a couple years back in the traders part of teh forum.

I bought an 11 row cooler with oil filter relocation kit for around 350 delivered, this was a couple years ago now. It worked well and I did around 10 track days last year, no issues at all

how much were you looking to spend?

there are univeral kits for about 350 - 450$ that have decent quality

I run a just jap kit...but with a different core. the quality is good enough but the lines are so damn long...ive got one that snakes all over the engine bay.

But it doesnt cost much to get them shortened to what you need.

I'm happy to spend $350 - $450.

Only thing being if their universal, does that mean I'm up for extra labour costs.

Thanks

well were you looking to install them yourself?

what area are you from?

sydney?

Wait on a sec, just to check, your car was running close to max temp yeah........which guage did you get that info from? Also, exactly what temp (in numbers) did it reach?

I have a HKS oil cooler kit, everything fitted up perfectly the first time, i reckon its worth the extra coin personally. Autosport Engineering in Kirrawee fitted it, go down there and tell the tall bloke that mx5 chris and stev0 told you to go there. Probably wont be cheaper but you may score a beer out of him :P

I got it from the factory guage (not sure of their accuracy, I've heard different opinions).

On a cold day the oil temp runs at about 100 degrees, sometimes a little higher.

Wow, that is a bit warm.

I found a second hand TRUST kit for around the $350 mark. It bolted up first go on my 32, and at the Wakefield track day the temps barely got over 90degrees.

What kind of driving do you do to get around the 100degree mark? Is that just putting around town, or really getting stuck into it?

Putting around town it probably runs about 90 - 95 degrees, but when I really put my foot down (for short periods of time) it runs higher.

I never hammer it for to long as I don't want it to overheat.

buy a trust kit. sure there are cheap kits at only $350 or $400 but at a workshop they can cost up to $500 to fit as there is a lot of stuffing around to do it properly (route the lines, make a duct etc).

The trust kits come with thermostat which a lot of the cheap kits don't. they come with good cores. they don't come with bonus bits of swarf or dags inside. they also come with lines that are the correct length not crazy long ones that have to be looped around. they also come with adapters to fit the proper filter for the car. they also come with quality re-usable earls fittings, not cheap fittings. plus they seal and never leak. they also come with all the extra little bits needed like mounts, ducting, conduit to protect the braid etc. It's easy to see where the money goes when you compare a $1000 trust kit to a $400 chinese kit.

I know which one I'd buy. and I have used a number of trust kits now on my cars.

one tip is do not get the radiator mounted one. get a kit that mounts the core in either of the side ducts. much better.

Yeah I tend to agree with you. I've used all high quality parts in my mods so far (including a trust intercooler) so why start using cheap parts now.

Only thing I don't understand is what's a radiator mounted one (do Trust make them?). How do I ensure I get a kit that mounts the core in either of the side ducts?

Thanks Paul

the radiator mount ones are ones that mount between the intercooler and the radiator. they mount to the front of the radiator. the problem is with no ducting there and other heat exchangers (intercooler, air con core and radiator) they don't get good airflow and don't work as well as they should. I have used one that way (a trust kit on my old 32 GTR) but it was not as efficient as the exact same core duct mounted in my other 32.

Yeah I've still got the stock radiator.

How would replacing that affect oil temperature?

Thanks

It would drop it significantly. Much easier to do than putting an oil cooler in too. Those cheap chinese ones from just jap and the like really work.

FYI I was going to do the same, buy an oil cooler that is...

Ended up buying a upgraded radiator and it dropped the oil temps by about 10 degrees. Also fitted a R33 thermostat to kick in earlier and keep temps lower.

Try that first i think.

      Boost level and torque curve

      By Lithium · Posted

      As someone who has been playing with turbo things for some time now, be prepared for this to not be the first time feeling this way    I'm busy as atm, but if no one else covers the things I'm realising are worth mentioning to you then I will when I have a chance as it seems like I overestimated your knowledge on how turbos and wastegates work.  Otherwise I recommend having a look around how wastegates and boost control work, really anything on understanding the general mechanism of boost control as it will help you find the answers to the questions you're looking for.  Your initial question jumps some fundamentals.

      so this is an anomaly??? I thought it was a voluntary increase

      we can only guess exactly what happened from our keyboards, but to me it looks like they were targeting 27 but the wastegate was too small or poorly controlled and the boost crept up, that is quite common

      Good points!  Took those for granted - though I *did* actually give an example of winding boost up more than it had been before where I wasn't actually specifically looking for more peak power.  The Toyota Starlet dyno plot that I shared and mentioned showed an overlay from the previous tune it had and the one I'd redone, I left the boost targetting the same as the old tune but then after peak power I ramped boost up by a good 5psi or so over what the old tune had at the same rpm. The reason I felt comfortable with this (though the owner of the car had a "are you sure?" moment when I suggested it) is that the setup wasn't turbo limited, it was largely head sealing limited and the owner was a bit concerned as for the last few seasons he'd had issues with head lifting - sometimes not completing an event without having some headgasket issue, so he didn't want to run any more boost than it was. The reasons I was ok with raising the boost a good 5+psi MORE than that was that I left it where it was in the middle, and only increased it where VE (and therefore cylinder pressure vs psi) were dropping hard and I didn't stop the torque from dropping, just reduced the drop.  Well, there is that and the fact that the previous tuner had it overtimed by near 7degrees at peak torque - but that's another story haha.    I didn't really go into detail about that "turning it up more" thing but now you've mentioned the "not detuning", sometimes the boost *can* be turned up higher than you'd expect if the setup allows for it and you do it smartly.  I've tuned things to run 30psi on BP98 "safely" that a few years ago (or still?) people would cry that it was a stupid idea - but given they were well intercooled, low EMAP turbos and only doing that kind of boost where VE is dropping etc I was pretty confident it wasn't as cowboy as it sounded at face value and we never ended up with issues as a result of it.
