Brent, if you're in Seven Hills often enough anyway drop into UAS down the end of Tucks Road and have a chat to them, they may be a bit more expensive, but have worked on quite a few Stageas around the area now and know what the go is.

First of all you need a new radiator, not another used one. Second you should be able to get one from a radiator repair shop. In New Zealand I can get a generic replacement (or a thicker one) with the hoses and trans pipes in all the right places. they just look in the Natrad catalogue. I haven't heard either way if this is possible in Australia but i should imagine it is.

An aluminium or any other radiator without the heat exchanger for the auto trans is no good (unless you have a manual of course). The primary purpose of the heat exchanger is to raise the trans fluid to its optimum operating temperature as quickly as possible and the secondary function is to provide additional cooling.

This primary function will not be acheived with more or bigger seperate trans coolers and since most trips are less than 10km it is important for the auto that the fluid goes through the radiator.

Yes the stock radiator has a plastic top but it has probably lasted 10 or more years.

[To give an example of the importance of the heat exchanger... her indoors was compaining that she would have to buy a new car because the auto trans in her Toyota Corona was stuffed and she didn't want to pay megabucks to overhaul it. It would n't change into top gear until about twenty minutes' driving i.e. normally not at all on most short trips. I fixed the problem with a twenty dollar thermostat - the old one was stuffed and opening at 55 deg so that the engine was taking forever to get up to proper operating temp and therefore so was the auto.]

You beat me to it re. the missing heat exchanger on aftermarket radiators Rob. I wish we could just buy the cheap alloy radiators from Just Jap etc.... but none of them cater for autos. Good fix with the thermostat.

Yeah or get it re-cored I guess; that is what I always thought I would do. Cause for a new stocker it would probably have to come from Nissan who would probably charge the earth? Pity we don't have something like Natrad in Australia... :) Maybe a re-core would be doable though just gotta ring around (same as a new radiator as I understand it; they replace the fins/core. although stag radiators have plastic end tanks, not sure if that makes a difference).

so its probably best to get a stock one then? lol less stuffing around straight out and striaght in. alloy would be nice though. but i will stop by UAS and see what they say.

went down 2 UAS in seven hills yesterday and booked her in for a service. Asked about the radiator and they suggested alloy straight away and said its better with the addition of the after market trans cooler than the stock oil cooler. rekons it would take 3 hrs to install? im thinking about it.

He said they deal with a few M series stageas... who of you guys goes there and how good are they?

yeah not just a question of cooling capacity (alloy w/big external cooler will cool more yes) but it's also important to not have *too* much cooling capacity when it's cold, with no way of heating the transmission fluid up to minimum operating temperature (which is what the stock radiator does - Rob explained it well in post #6).

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      I already have the ability to datalog the voltage... what I can't do is correlate it to what the gauge is showing when I'm looking at the data at a later date. Or something like this. Except getting the oil to 125C+ involves me going 200+kmh at the track so you can imagine this is a little tricky unless I do something like note what the voltage is when I am at the top of 5th gear so I have a point to reference on. Drove car today. O2 still reading richer because hopefully not a leak instead of massive restriction I've introduced. Car really doesn't sound like a LS. It's quite strange. Pulled a bit of fuel out up top. This does potentially explain why my spark plugs looked like the car was running pretty over-rich. If I was tuning it to a ~12.7 which in reality was far richer than that in the past. It will be handy to have the dyno WB to compare my WB to to compare notes that's for sure. At this point I'm happy to just sit in the passenger seat and tune the thing given I've got about 7 million hours on the platform lol.

      Yeah I understand you have to pay for an updated map or subscription service or something. But I can't even find a current map for Australia. My map is dated 2017, but didn't this car version still sell in Australia until 2021?   Also, just as an aside, the navigation system warns you of traffic incidences ahead.....why would they include that on a map they knew is not receiving live information. I am forever going to be warned of an incident that probably existed for 30 minutes 8 years ago.

      Run it in open loop for now, and drop the frequency down. This lowers the resolution and requires more duty cycle to do anything, however good to troubleshoot.
