I was running twin 12" thermos on a dedicated track car and a disconected clutch fan.

i found that temps went abit weird and all over the place (had the thermos wired and re-wired a few different times to fix the problem and nothing)

hook the clutch fan back up and she was sweet. this was on an sr and ive had another mate have the same problem with his rb20 and his new car (black top sr)

like i said, it was my personal opinion and on a track car i didnt like it and neither did my car

Abe, help us to help you buddy.....ie.

How much power are you anticipating?

How much track work will the car see?

Is it your daly and if so, how much rush hour driving will it see?

and most importantly, what is your driving style like, ie. boot into it from most traffic lights (which is how I drove when I was younger) or just the occasional squirt, etc?

All the above factors have a big say on clutch choice but having said that (and as Steve stated) you couldn't go wrong with that NPC setup from the little I know about you and your car.

Hope this is all helping bud, cause I was the same when I was trying to decide on turbos and zorsts before selling mine.

Thanks for the help Pete.

At the moment it has ~260rwkw, will eventually go higher when i rebuild the engine - if it dies.

It will be seeing 1-3 Days a year at the Track - Depends how many SAUSA does.

Yes, it is my daily, generally it is a straight run to work, with 1-3 traffic lights. But as for slow moving, bumper to bumper traffic, very rarely - hardly go anywhere near town, closest i get is maybe Vilis :D.

Take off from the lights is generally sedate, but will sometimes give it a bit up to the speed limit, also very rarely go for hills runs, but will be going on a few more hopefully as i now have weekends off :(.

what fmic kit did you get? you shouldnt be cutting up your fan (found out the hard way)

also, personal opinion, thermo's are shit if your also removing the clutch fan.

Never said I was cutting up the fan ... hence why I removed it.

I've removed the clutch fan and fitted thermos to my previous project cars ... including a supercharged SR20DE powered 200B and CA18DET VG30BB turbo powered 1600, and never suffered overheating.

I'm just asking what thermos (for those who are) are being used on RB25DETs.

I'm running a single 14" thermo and even on the track i have no problems with temps.

The problem with clutch fan is that they produce parasitic loss all the time even if the temps are fine. The advantage of the thermos is that they only produce a power loss when the cooling is actually needed which you will surprised to know is only around 30% of the time (more if you are in stationary traffic obviously). When the car is moving generally you don't need any more air flow than what you are getting by the car moving through the air.

Which is my thinking too. What 14" brand are you running?

I'm also running a 52mm alloy radiator. :D

We found in our old drag car that the a/c thermo off a vr/vs holden did a fantastic job, but they are a 16" fan. Other than that try to get one with curved blades and preferably with an outter ring to stop the blades flexing too much.

LOL, sounds like James would make a good candidate for a Mod with his stick wielding talents .......**mental note** :D

yep thats a definate, theres a couple of people from that party im willing to bet are still showing the marks of a good banning now.

never said you were cutting them (i can read and saw what you said) just said you shouldnt also why i asked what fmic piping kit you had as despite the kit you shouldnt have to cut the fan blades as any decent kit made should fit between cam cover and fan shroud without hitting the fan, thus no need for thermo's on a daily car. :D

get thermo if you want was just trying to save you the time and money as they arent needed. also gave you the brand that ive used so go for gold :(

i like to think of myself as a pretty patient guy....

BUT FOR PHUCKSAKES I WANT MY SKYLINE BACK AND FINISHED!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Err....fairly sure that needs to be changed. :)

Yeah, i know what you mean. Mine has been off the road for 2-3 weeks with a fried clutch, and its going to be about another 2-3 weeks before its good again :)

Aberax i see your having troubles deciding what clutch to choose..... I highly recommend the same one that i got which was through the group buy that madaz did. I had an R33 GTST with 250 RWKW and i hammered the thing with no problems at all. Before this i went through 2 other clutches. The NPC setup was VERY easy to drive and was capable of a fair amount of abuse ;). Good luck in what ever clutch you choose to go with :)

Ive been waiting since November for my engine. Been driving an R32 with a busted engine since October. I win :)

Sp you have a 5puk Ceramic from Steve's (Madaz) Group Buy? Did you also get the Flywheel too, or have your old one machined?

^^^There you go Abe........just get the NPC bud as it's less than 1/3 of the cost of a Nismo and very good clutch for the $$ by the sounds of it

LOL i don't know what your complaining about, my cars been off the road since march last year and i have only now just started to build the engine.

Which is my thinking too. What 14" brand are you running?

It's just a generic one off eBay.

    • You just need to remove the compressor housing, not the entire turbo. I would not be drilling and tapping anything with the housing still on anyways. 
    • So, I put my boat on a boat. First of all, I'm going to come out and say it. Why is Tasmania not considered a holy goal, an apex that all road-legal modified cars go to, to experience? This place is an absolute wonderland of titanic proportions. If people are already getting club runs for once in a lifetime 30 person cruises to Tassy then I've never seemed to see it. It is like someone replaced the entire place with an idyllic wonderland for cars, and all of the people living there with paid actors who are kind, humble, and friendly. Dear god. After doing a lap of almost all of the place I've found that it's a great way to find out all of the little things that the car isn't doing quite right and a great way to figure it all out. All in all, I drove for 4 hours a day for a week and nothing broke. I didn't even need to open the engine bay. This is by all means a great success, but it has left me with a list of things to potentially address. I also now have a 3D printed wheel fitment tool which annoyingly hasn't got any threads in it to actually assemble it. I might be able to tape it together to check the sizing I actually want to use, but it'll likely involving pulling the shocks out to properly measure travel at least at the front, and probably raise the car while I'm at it, at least in the rear. I scraped on quite a few things and I'm not sure how else to go about it. I was taking anything with a bump at what felt like 89 degree angles. And address those 10 other tasks. And wash the car. God damn it is dirty. And somehow, the weather was perfect the entire time - And because I was on the top of Mt Wellington it turns out it was very much about to freeze up there. I did something I typically never do and took some photos up there in what must have been -10 and the foggy felt like suspended ice, rather than mere fog. If you own a car in Australia, you owe it to yourself to do it.
    • Damn that was hilarious, and a bit embarrassing for skylines in general 😂 vintage car life ey. That R33 really stomped. Pretty entertaining stuff
    • Hi, I have a r32 gtr transmission. Does any of you guys have an idea how much power it will hold with the billet center plate and stock gearset? At what power level and use did yours brake with or without billet plate? Thanks, Oystein Lovik
    • Saw this replica police car based on a Mitsubishi Starion XX parked next to a 'police box' (it's literally a box) in Hirohata, Himeji City in Hyogo prefecture the other day. It's owned by Morii-san who is a local Mitsubishi Starion enthusiast. According to a local radio station blog post, he always wanted to make a police car himself based on ones he saw in his favourite Manga comics.  As it's illegal to modify a car to look like a police car and drive on the road, Morii-san tried many times to get permission from Aboshi police station headquarters nearby. They refused initially by after they got tired of that they granted him permission. However, the car can only be displayed on private property and obviously can't be registered as long as the police livery is present. The car was completed at a cost of 1.5 million yen (US$ 10,000) in addition to the car cost. A location was chosen outside Hirohata Police box where the car can easily been seen from the street. Morii-san has two other Starion road cars, both widebody GSR-VRs.
