I finally found a picture of the cooler i currently have cooling my rb20. I think its of a 7MGTE (MA70 Supra).

Does anyone have an idea of their level of efficiency, ie, how much boost can safely be run through it? im upgrading soon though still would like to know.

Its the bigger one pictured with inlet/outlet on same end.

cheers

Hi Timd, I used one of those for quite a while, very good cooling. The inlet air temperature drop was very good, much better than many other similarly sized intercoolers I have tested. It did get a bit of pressure drop over 1.1 bar, but it wasn't terrible until about 1.3 bar, then it went verticle. At 1.1 bar it made ~175 rwkw on an RB20.

The inlet and outlet are 55 mm, while the standard RB20/25 pipework is 62 mm. So, if you are going to use one, you will need a couple of silicone reducers (2.5" to 2" is the common size).

Hope that helps. :)

Thanks for the reply mate

Just what i wanted to know, i wouldnt be running more than 1bar through it so it is still within its limit, good stuff. I am still going to have to upgrade though. As i have turbo inlet, i/c inlet and outlet all running ontop of each other due to the in/outlet being on the same side of this cooler. This leaves my pod tucked up in the left corner getting bugger all cool air. My plan is to run the i/c out pipe under the drivers guard and into the bay, behind the radiator and up over the rocker cover. This should free me up some space for an air box or at least cold air ducting. Its tricky in the 280zx as theres not much space to work with.

Do you know if there has to be any engineering if i cut a hole in the engine bay(leading out to under the guard) for i/c out pipe? Should it be reinforced in the event it may cause weekness?

thanks again

    • Oh bugger ! Your right ! Good old hydrogen sulfide. Takes me back to the good old school days ! 
    • I've owned a few scooters over the years, a Vespa PX oil burner was my first scooter, followed by a few others, including a little 50cc BeeWee that I used as a barracks bike, and I've had a blast on all of them, they really are the cheapest for of city/suburb transport around The only issue with scooters in Australia is lots of people look down on them due to their size,  maybe they need a big bike to make up for something else where they are lacking, unlike Europe and Asia where every man an their dog owns one, and now that filtering is legal in NSW, local traffic is never a issue Not to say I haven't owned my share of big cc bikes over the years, but they were for more blasting through the hills or Hwy riding where it needed to sit on Hwy speeds Safety wise, I ride like everyone is always trying to kill me, everyone is running a red, or running stop/give way signs, or generally asleep at the wheel, which most people are duringtheir commute, I also ride really safe, and give myself, and everyone else enough room in case I need to pull some hasty evasive actions, I've done a few rider training days over the years, which has come in handy on more than a few occasions  As for mods, there's nothing really, and yes your right about aftermarket exhaust, all you get is loud and obnoxious noises from them, like every 250-300 cc you hear with a aftermarket muffler, in saying this I did put a rear muffler from a 125 Aprilla on one of my old 125 scooters, it was horrendous and no amount of full face helmet and ear plugs would dampen that noise As for coming from the Harley, and what a overpriced POS that was, I no longer do big rides as my poor old busted joints ache after about 1/2 an hour of riding, long cruises are so much more enjoyable now in a car, so a big bike would be pointless   
    • Oh wow, it's easy to forget how cheap these can be. Probably the cheapest way to travel. Though people in cars here tend to be morons and I would not feel very safe. Were scooters ever big in Australia? It used to be the thing growing up in Europe ~20 years ago. 50/70/125ccm Peugeot or Yamaha and some others. Utterly obnoxious Polini race exhausts. Kick stands that slant as much as possible. So loud. So much noise for really not moving very fast at all. But it felt cool at the time. Not sure where I'm going with this, but there is an aftermarket for mopeds! Though I'd have pictured you more for a Goldwing kind of guy after growing out of the Harley.
    • You need to know I am sorry for this.  
    • As the MX5 isn't apparently "manly" enough, and I need something for runs to the local shops, and also take to my part time job at the salon, basically I can keep the MX5 away from car parks and stuff......like "flying lockers", I was wondering what I could buy to fix this issue LOL, I pick up a new Yamaha 125 Delight this arvo from Trooper Lu, basically a R1 that you can fit a slab of beer on between your feet, also, it was $29400 cheaper than a R1, so actually it's 2 x better than a R1
