There's something I always hate, having to topup unknown existing coolant risking a reaction between the 2.

The best you can do is Genuine Nissan Long-Life Coolant (LLC), from a Nissan dealership. 1 litre of concentrate cost $10-$15 and makes 2-3litres (depending on a 50:50 or 66:33 mix of water:concentrate).

The cheaper option is Nulon concentrate that meats the Nissan specification (Nissan LLC I think is the technical name)

get the Nulon Pre-Mixed (green) coolant ..I paid $20 per 5l canister just the other day. Don't just top up.

If you've got an hour or 2 I'd highly recommend taking out the factory radiator and hosing the fins down (carefully) mine was completely blocked with bugs and dirt.

Flush the system, and use genuine Nissan LLC. But don't mix it stronger than 60:40.

If you use the genuine stuff, and change it every couple of years, the alloy bits won't corrode, simple as that.

Hi Guys, just bought GT-T R34 pretty much stock overall. Noticed the coolant is way below the low line...is there something you guys recommend and from where I can get it or can I pick up anything from the shelf.

Thanks

Hey guy any chance you would know how many litres an r34 gtt would hold as im replacing the radiator and dont know whether to buy the 5ltr LLC ($62) or a couple of 1litre ones at $16 each

Its inbetween 7-8L (cant remember) you dont need 5L because you have too mix is with demineralised water. I suggest 4L or less of LLC and the rest demineralised water too get a 50\50 min or less. To much coolant and you wont be helping your engine cool at all.

Edited by central coast person

it takes 9 litres for the whole system but you will struggle to get even 3l in there unless you properly flush the whole cooling system (there's a few threads about that too) Don't forget to bleed the air.

    • Damn it, I was at work last night, and stayed in a room there during the storm with the car outside, but undercover, I just went downstairs and well....there was a large steel locker that has come from some place last night, it wasn't anywhere I could see yesterday, and yeap, it landed on the fraking car....of course it did..... LOL So, I'll need to take it back for paint and panel, luckily it was only the boot that took the hit, so it could have been worse Serves me right for staying at work and getting on the cans with some of the boys
    • Yeah, really happy with how it all turned out As for aftermarket lip, nah, I'm not really a fan for practically reasons on a street car that gets driven everywhere  I did have the full lower kit on my 2015 STI, but found the front lip scrapped alot, even at stock 4x4ish ride height As the NC sits now, with the lowest point of the car at 110mm, so just legal, some steep driveways and steep speed humps will still "just" scrap those little plastic OEM air dam thingies on the undertray just before the front wheels
    • Here's one I help build and tuned a decade ago, Garrett  GTX3071R Gen 1, T3 twin scroll 0.83 rear housing. Went from larger 272 cams down to smaller Tomei Poncams to help with the low end. S13 non VCT motor. Car was purpose built for the track, hence low down was the focus. Note the actual dyno chart shows lower boost, however the EBC and boost gauge showed 1.9Bar (Ignore the torque, I was young and didn't know how to set derived torque)  
    • I’m doing some side developments on SR20det S13 engines, its one my hobby cars used it to compare flow capacity of some smaller size wheels. SR20det is one of another JDM legendary engines I'm sure there are plenty of SR enthusiasts on this forum, I will share results some common turbo configurations here. a quick run down of what the car is: Wide body 180sx Type X with black top engine (blue). It has: Stock bottom end Haltech 1500 ECU 5-0 motorsports trigger kit Kelford SR20DET Beehive Spring with Titanium Retainers Kelford Cams SR20DET S13 188-B 268/272 Cams G25-660 Turbocharger in T2 .64 rear housing internally gated ARP Head studs MLS head gasket 1000CC ID injectors Walbro 450L Fuel pump Front mount cooler kit JJR’s 3 inches turbo back exhaust (its too short for the 180sx it had to be extended) Pump 98 fuel Hub Dyno tune So far made 270rwkws at 22psi full boost by 4500RPM. Engine is very knock limited hence a pretty bad looking top end. From previous experiences it seems like SR20dets are happier with bigger size turbine, some thing like a GT30 would make way better top end, but on same time response is lost. It won't be a problem with S15 VCT engines. I'll be testing alternative turbine housing, turbine wheel and possibly dump pipe options for extra flow to resolve the problem and of course E85 would resolve all the issues.            
    • Awesome writeup and details. Thanks for sharing the story so far. I can relate to parts of it with my previous car and some of the issues I had to deal with.
