    it was two specific problems with the freddy inlet - a leak around the press fit stub pipe to the radiator - it wasn't sealed and weeped very slowly, eventually caused an airlock in the top hose and then .. and overheat.

    then when I took it off one of the bolts was rusty - turns out there was some porous aluminium in one point as well.

    I wouldn't buy another, not with the japanese yen at the price it is at the moment, the copies aren't worth it.

    the GReddy ones can't fail around the radiator outlet in the same way as they're threaded and sealed, rather than relying on a press fit for a water tight seal.

    I've got to say, mine runs fairly hot - I will have to install an air to air oil cooler at some point but for around the normal roads, it's OK.

    yeah on roads mine is fine and the fans are controlled by the z32 ecu so they come on if its getting quite hot, even at the ring it did fine, it just runs hot id like to get it running a bit cooler too if im honest

    update .. it mostly just .. works

    I've just been driving it(!) to put some serious miles on it to properly run it in - I'm now using boost rather more, even with 0.5bar of boost, the twin turbo setup pulls well - my arse dyno says it currently feels around 280-300hp but with really, really nice responsive pickup at the low end.

    I think with full boost and the S15 injectors I have planned for it, a responsive 370-400hp isn't beyond the realms of possibility.

    I've got some more refinement of the cooling system to do - after some blats on a motorway, the water is getting too close to 110C for comfort (measured in the top hose). cruising it's around 100C once it's heatsoaked.

    oil temp (measured at the filter housing) is around 90-95C when the water is at 100C, the oil reaches 100C when the water is getting close to 110C.

    before you start really giving it some beans, it'll happily tootle around at 90C (water) continually, suggesting the heatsoak seems to be the major issue.

    the things I'm going to try:

    two aluminium plates riveted to the sides of the radiator to close the gaps up on each side.
    seal the back of the kouki indicator holders - right now, they're up against the intercooler but as they're slatted, they let air get into the wheel arch liners rather than pushing it through the IC and then to the rad.
    upper cooling panel to stop air flowing over the top.

    I've already got the OEM undertray on at the bottom.

    potentially a nismo thermostat, though I don't fancy this much, I don't want to overcool it.

    if anyone has any suggestions, they're welcome to chime in.


    my speedo is now fixed too, courtesy of Dom over at picbits.co.uk, one of his boxes is sorting my RPM out too

    oh and final point - measured the fuel consumption last night.. mixed driving, involving the motorway blats mentioned above, some cruising, around town - fairly mixed use ... 26mpg (!)

    I'm rather pleased with that.

    right. long bump on this one.

    the 180 still lives, though it's looking a little sorry for itself. I'll get some current pics soon.

    I crashed this in 2016 and due to life taking over and agreeing to fix a friend's AW11 MR2 that was mostly made of branflakes, I've been pre-occupied with that for the last .. 3 years.

    That's about to be finished though so I'm starting to get things together to fix this - I crashed it on the motorway in 2016, not too badly, low speed and crumped the front passenger side corner. I've already got all the metal work I need to be able to fix it, so it's welding mostly to sort out.

    If anyone has any arch liners for an S13 - please let me know, it's about the only difficult thing I've got left to find

    Bollocks, just realised the old webspace I used has been turned off. Will get the pics re-uploaded and re-tagged.
