replace the catch tank with the bigger cusco one that sits in front of your battery. you still have a standard sized battery so it'll fit there no problem. also consider installing some improved cam cover baffles it will help stop so much oil making it to the can. the mines ones are excellent. plenty of copies available now but I like to do the right thing and buy the originals, they are not silly money.

here's a pic of the catch tank I mean in one of my cars. it's the 'racing version' and from memory is 3 litre size and fits very nicely. sorry it's not the best pic as you can't see the whole can. it also runs much bigger tubing than the small one you have.

just a quick question about your pic BB, is that gtr in the pic still running A/c? or has it been removed? im just looking at the oil cooler. you have so much room there.... my car is so tight i cant fit my cooler anywhere but down in the front bar... so shit

yeah it's still running AC and still functioning too.

you can see the AC core is the black core you can see either side of the oil cooler. the radiator is a sard radiator and is unpainted. the intercooler is a trust 3 layer core and is in front. you can see in the pic the radiator is mounted behind the radiator support, none of it protrudes under the support. the air con core is what is mounted under the radiator support and up against the radiator.

to be honest I much prefer to mount the core in the passenger side 'brake' duct on R32's. you can use a smaller core and with some good ducting and an exit path for the air cut into the plastic wheel well liner they work very well. my other 32 is like that. this one already had the oil cooler fitted and I think that core is too big to stuff into the area where I would normally put them. it seems to work ok though, but in the guard is better.

PS. what exactly is getting in the way? you're welcome to come and check out the set-up if you want. some stuff has been moved around a bit to make room etc. like the power steering bottle etc. check out where it sits. car also has no abs which makes a bit of room (not utilised yet but will be).

Here's a video of me driving (badly) at Hampton Downs (just outside of Auckland), constructive criticism welcomed :)

Can someone show me how to embed this in my post so the preview shows rather than the link?

yea my car runs no abs (nismo edition), there just dosnt seam to be any room there, ive got a 52mm alloy radiator, factory cooler. My oil cooler is in the front passenger brake duct like you have said. and i have a slot cut in the wheel well, with mesh covering it so rocks cant smash my cooler. ive mounted it in there took me ages to make up brackets and things, it just looks my efficent, where yours is in that pic. my car runs quite hot compared to My mates 32R, his got no Ac but and his cooler is mounted where yours is, his also got a factory radiator.

Ive got a Nismo Thermostat, 52mm alloy radiator, oil cooler..... but cant quite keep it as cool as his, in saying that its not geting Hot Hot, temps sit around 80deg on a warm night, and get to 95 when into it. i also dont have a shoud on my radiator so i think that is whats making it run hotter. Im in the middle, of fibreglass one, alil bit of sanding tomoro and she'll be ready to paint, ill see if that fix's it. ive got a good feeling it will.

that thing is awesome man, i love the welds on the cage!!!, it looks really responsive out of each turn!!

what type of radiator are you running? if it's a china one and you still have your stockie try switching back to the stock one with stock shroud and see how that goes. I've seen enough GTRs now go backwards cooling wise after fitting chinese radiators. the standard radiator providing it's not got the worlds biggest intercooler in front of it works very well.

you got any ducting around the oil cooler? my other 32 has the same trust kit as the one I just pictured but with a smaller core and mounted in the passenger side duct. it runs nice and cool, it has aluminium ducting around the core to channel the air through the core and then our through the exit path holes in the guard liner.

are you still running the standard engine fan too?

I got no idea what brand the radiator, it came with the car when i brought it, im guessing its a china casue theres no jap brand lil plarks on it anywhere. i wish i did have the stock, i would deff put it back in.

the cooler is a trust i think 7 row, it fits a lil sideways but basicly right in front of the passenger side vent and the air either has to go through it or it will just hit the intercooler pipe work. but theres nothing channeling it out to the rear exit, thats a very good point, mite make somthing up, so once the airs gose through the cooler it gets shown the best way out without swirling around and shit.

and yeap still got the stocker fan in place. ill finsh sanding my custom radiator shoud today and fit it up, see if it makes a diffrence.

i also had a look in my bay yesty, to see what was in the place where your cooler is on your.... my A/C condenser is there and about 4 other small black alloy pipes that run from the condenser to the a/c core.... they must have removed all that stuff for your car and re positioned it, cause theres noway you could fit anything there with mine, ill post a pic if you like.

cheers

yeah that stuff can be fairly easily relocated a bit.

definitely do a little duct for your core. I'll see if I can find you a photo of mine with the bumper off. it's very simple but works amazingly well. air will always follow the path of least resistance so without some ducting around the core air will just hit it like a brick wall and then flow mostly around the sides of it, not through it like we want it to. it will still work but it works many times better with the air actually flowing through the core not just over it.

consider something like this for the intercooler opening too. means you can get away with a smaller (or even standard intercooler) on the track as it's efficiencey improves a lot.

actually you can see part of the oil cooler duct here in this very old pic of my car. on the passenger side. also the middle 'slat' is removed to allow more air in there. it channels the air through the core nicely.

found another similar pic, possibly a bit clearer.

I have one somewhere with the bumper off. will try and find it for you.

BINGO. found a pic showing the simple duct. it works wonders.

EDIT: make that 2 pics.

You can see how much smaller this core is than the other one but I'd say it works just as well if not better. the ducting is so important.

I would also consider buying a used standard radiator and shroud and put that on. I bet it performs better than the current china radiator and no shroud combo. and just wait till you pick up a china radiator and compare the weight to a standard one!! china radiator must be about 4 or 5kg. standard one I'd say less than 2kg. and that's empty. obviously the bigger volume of the china ones means more coolant and even more weight. and in my experience they do a worse job than standard of cooling.

It's a cheap experiment and takes only 10mins to change a radiator. so I would definitely give it a go.

Rightio lads,

Small update, slowly working towards fixing the over oiling issues.

New oil catch can is done, holds a lightweight odyssey battery which is new also.

The can has a sight glass on the side and a small tap on the bottom to drain the oil (which we'll eventually remove the tap and run a return feed straight to the sump so it will just gravity drain.

We're not quite at the removing the engine stage yet so we can't access the sump to weld return oil feeds from the catch can and the breather plug on the back of the block.

We may just tap into the oil feed return line from the turbo to self drain the oil catch can for now.

In the pipeline is

- Cam baffles

- Oil restrictors

- Drain on the back of the head http://www.spoolimports.com/content/SPOOLR...OilDrainKit.asp

intercooler shroud. basically seals off the gap between the intercooler opening in the bumper and the intercooler. helps force air through the core instead of onto and around the edges. good mod, definitely improves the efficiency of the thing.

I bought a few in japan a couple of years ago. I may still have one or two in my garage. no idea who made them though. but they were nice enough and work well.

you can also DIY one with some bits of thin sheet alloy if on a budget. seen it done many times and quite effective but does look a bit 'race spec'....

    • Yeah i found that alot of parts can be wrong or "very" hard to get the real right one. I already bought some brakes years ago on me "old" GT calipers and they were wrong too 😄  I told them too. Even send them pictures...but they said "EBC catalogue has them on my car... So i dont know what their answer will be. I call monday them and let them know that they are really not on my car. If they were they would be already on a car...
    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
