Radiator Upgrade

[chook]

Got a leak on my top tank Radiator seam, could prob get it recrimped/sealed but id rather put the money towards an upgraded radiator, as i have experienced a high needle towing my boat last summer.

Anyway, my question is, since most/all upgraded radiators are designed for Manual transmissions, without the internal tranny cooler, can I forget about this cooler and just rely on the S2 external transmission cooler, which is quite large ? ie what % of cooling would the radiator transmission cooler perform ? maybe i could fit a secondary external cooler ? any ideas ?

Im looking at getting the KOYO type-Z radiator.

Would this one fit? http://www.skylinesaustralia.com/forums/t187748.html

Edit: Sorry just read about the trans cooler issue... was going to suggest a davies craig cooler like sydneykid's setup; then I remembered that the trans fluid gets piped through the bottom of the radiator to WARM it up too to get it up to operating temp as quick as possible. So I don't know if that aluminium job would be suitable; but if it could be made to fit into a C34 chassis it sure looks like it would keep the engine cool

Already bought the KOYO, much larger than the factory.

Ive also got a davies craig cooler from my last R33, together with the large S2 stock tranny cooler should be fine. Regarding bypassing the radiator cooler, ive read some conflicting advice, davies craig website says it is fine, just a slight loss of cooling. Considering the radiator thermostat wont open for 5 or so minutes, it wouldnt have any warming effect initially, dont think it is an issue for Australia conditions. Ill check with a few experts before installing.

Fitted new radiator today, did timing belt whilst I was there, tomorrow fit secondary Auto cooler in lower area in front of wiper bottle. Radiator is significantly larger than stock, shouldnt have any more worries towing in QLD summer.

Chuckie, havnt got a powersteer cooler, is it only needed if you are throwing it around a lot of corners, or just for everyday usage ? Are you running 2 Auto coolers or just moving factory cooler ?

Gday, i do about 400k per week, i can remember a power steer cooler on my R33, wonder why nothing on the Stageas, maybe since they were designed for snow. i also run Transmax Z in PS and auto to run them a little cooler, although both are looking brown.
