Oil Cooler Vs Transmission Cooler.

Hi fellas,

I am planning on adding performance parts to my R33 GTR and was thinking of some oil coolers. I understand most people often add oil cooling units for either their transmission or engine to cool the oil in them. My question is, which would add some noticeable performance gains and would both be good?

Moreover, to get a few extra kilowatts of power - would larger injectors and an aftermarket fuel pump add anything. I'm currently running a stock engine with only performance coilpacks and spark plugs so would this add anything?

Cheers,

to my knowledge there are NO performance gains other then keeping the engine healthy and lowering high oil temps though track or industrial area abuse.

although lower oil temps could mean better turbo performance as they don't like high oil temps

Thanks mate...

But should I get both oil coolers or just one for the engine?

Cheers.

thats one thing that i'm unsure on, if lower gearbox temps will make the gear box last longer and not blow/less likely to blow then i'd have one in yesterday, fairly easy on the rb20/25 as u just use the auto banjo bolts and hard line.

i've been meaning to ask if there's any real difference or can you still kill your box just as easy?

Kevin don't you just drive your car around on the street? What on earth would you need a tranny cooler for :)

You do realise the point of an oil cooler don't you? It is to keep the temps from climbing high which will cause engine oil to thin. Meaning unless you drive your car very hard on the streets, it aint going to be doing squat for you.

You have been on these forums for as long as I have and you ask a question such as "would larger injectors and an aftermarket fuel pump add anything"....

Thanks mate. I'm a noob - not going to try and deny that. :-)

Basically, I'm trying to add some extra power on my GTR but don't want to upgrade turbos as I find them very responsive. Wonder if there's anything else I can do...that's why I raised these questions... thanks mate.

injectors, pump, FPR, and a new wastegate spring, or a new wastegate all up, of anything a hks one. but thats HKS money.

with the 440cc injectors you would be limited to the 300kw mark, same as the stock pump i guess.

go for 550cc, tomei FPR, and either a HKS wastegate or a 1 bar spring/s for your ones now. then add a decent BOV that wont kill itself above 10psi.

there you go, that should pull you up to about 300kw at the fly.

thats assuming you have a decent exhaust fitted before all else, whats the point on putting in more if you cant remove of more.

You missed the main thing he needs if he wants more power, an ECU.

Basically if you want more power these are your steps for your 33 GTR:

1. Exhaust

2. Cam gears

3. Boost controller

4. ECU Tune

5. Clutch

He doesn't need an aftermarket FPR.

Kevin if you really don't know much about performance modifications start searching in the Forced Induction section. It has been covered MANY times. Or simply go see Trent or some one regarding a package he would recommend.

your way would be the proper way of doing it. like if you have alot of cash flying around, but then again, rb26 parts are getting hell of a lot cheaper than the rb25 parts.

my way was just replacing the ecu upgrade with a FPR, a hell of a lot cheaper. but then again, nowhere near as good as a ecu.

p.s, i also think the performance section would cover just about everything

^^ This!

But I would not push the stock turbos over 1 Bar (14.7 PSI) unless you have steel internals.

what if the car is auto? even on the street, autos benefit from a cooler once you increase the power. so keeping that in mind, auto trans cooler or engine oil cooler? both w thermostats of course

If your skyline has that tiny single-loop-of-pipe trans cooler then yes, I think in an australian climate its an important upgrade, even on a stock vehicle.

      I know mentally you're set on the ATS clutch but honestly I'm a big fan of the Nismo Super Coppermix Twin. It's much cheaper and in some ways I think it's a better design for a street/circuit car.

      Just checked in first post and you should be able to bring it home November this year, right? I'm amazed you made it through four years of this. As hard as it feels now the rest will go by in a breeze in hindsight, I'm sure.

      Realized I haven't been back here in a while. Still here, still alive, still waiting for the car.  I went back again the only time last year from Oct-Nov for R's Meeting and drove it around some more, including a few laps on Fuji Speedway(in the wet, sadly). The car still feels good, but have a couple small things to address. I've been getting more parts but have slowed down still, and most of the bigger purchases are now out of the way. I find myself getting impatient more and more when it comes to getting started on this project; it's quite hard for me not being able to really dive in and start making this car my own because it's halfway across the world. At times it doesn't even really feel like I own one of these. Haven't really been motivated or had the desire to document the last trip on here or social media for, well, reasons... but here's some pics...it's also still alive and well as you can see: I've narrowed down to the last large part purchases(anything over $2k) before the engine build to be: 1) Ohlins Road & Tracks 2) ATS Twin Carbon clutch 3) Endless BBK with some custom options and 4) Kansai Service carbon driveshaft I don't think the budget exists for all of these this year, but I'll try for one or two items I think. Though, every time I look at my spreadsheet I sigh, shake my head, and get depressed just that little bit more.  'til later.

      It's a stunning location!  I've been to NZ twice but haven't made it to the North Island yet.  Definitely on the cards but the South Island is hard to tear yourself away from too... Looking forward to see what you can wring out of it once you can get it to hold together!  Be awesome to get a low 11 or even sneaking into the high 10's pass out of it.  That's a bloody quick car that most people will never experience in their life.  Enjoy!

      Nominally yes but I’m not really at that stage yet. Outsourcing to Japan is also a relatively good deal at the moment because their currency has devalued much more against the USD.  You would assume this but a lot has changed from the pandemic. Mechanics are in short supply and demand for fixing old cars has gone up from the cost of new cars. 250-300 USD/hr is not an unusual shop labor rate in California and you’re paying that regardless of whether the guy is competent or not. Coworkers have been quoted 3000 USD for a water pump and thermostat at a dealer on an N54. Oil changes went from ~75 USD to 150 on fairly normal cars like Civics. The cost of the oil and filter hasn’t even kept up with inflation.
