tt manual, is there any difference between the two, if so can a jap rad be fitted to a uk car

I had a Jap manual rad in my car and I bought a UK manual rad because I thought they had a larger surface area, as it turned out they were identical. Doh!

They're not - the UK one has 25% more cooling surface.

Well either they disguise it bloody well or I was sent another Jap rad ...

Having a UK and Jap rad sitting together now I can confirm they are identical

cheersfor that lads

i thought the uk spec car's had bigger or better rad's ,oil cooler's etc ...as you need a oil cooler on a j spec auto ????????? :confused:

 

or is the N/A rad smaller or bigger than a TT one ...????

 

 

..

Oil coolers are definitely different, UK one is about 3x the size.

Only the oil coolers are different..........Rumour was it that the diffs were different too but i am not so sure

UK model has a diff cooler, Jap one does not.

Stillen quote re rad

The 17% uprating for Europe may or may not be correct. Or maybe its all in the matrix density and it otherwise looks the same. Maybe also that Import ones were never intended to cruise at over 112mph hence the apparently smaller cooling, smaller oil cooler and no diff oil cooler.

Quote from the Stillen site

"Extra-cooling, heavy duty 300zx radiator. The 300ZX Twin Turbo is a world-class supercar, capable of tremendous power with moderate modifications. If you are going to be racing or pushing the limits of performance, you need greater cooling capacity. This oversize radiator increases cooling capacity by seventeen-percent. Designed originally for the 300ZX Twin Turbo models shipped to Europe for running high-speed on the Autobahn, the radiator will keep the engine in its optimum operating range even under such extreme conditions. Application: 90-96 300ZX Twin Turbo Manual Transmission, 90-96 300ZX Twin Turbo Automatic Transmission" unquote

 

is what it said - sorry the link above doesnt work right

So that sounds like a Stillen upgrade, rather than an OEM mod. Like you said though, it is possible that there is something different about the core, but to all intents and purposes the two radiators look externally identical.

It was an upgrade for Europe, but not us. It was mainly zeds supplied to Germany cos it was believed that with them having the unlimited autobahns, they would need more efficient rads, in that case, why didn't any Manx zeds get em :D

edit, doh just re read yer post, me twit!

Anyone got any pics of a UK diff cooler? I run high speed 200-300 mile runs so may make sense for me.............

 

If i can retrofit it to a jap diff even better
