Kit is on order from gouky In the us. Still going down that road. The 2nd gen is just a bandaid for a while.

just beware, that you may fit this and you don't have a HG issue and it could be you cooling system, rad etc. as mandalay said, check the temp of the coolant hoses both off the head and the one pre thermostat to see if water is flowing thru rad back into the motor.

^ what he said
Assume nothing.

So check the hose pre thermostat from the radiator and check the hose from the coolant outlet assembly to the radiator?

Radiator will be coming out on Sunday. How much of an asshole job on the mr2 scale would you think this is?
Also, what coolant do you guys use? The guru put the green **** in mine and from what I have been told, it's the wrong stuff.

Green = wrong. Most green **** contains silicates and borates which are bad for your water pump seals etc.  I had an argument with a Mazda dealer about this when my gf bought her Celica. anyway...
 
Use either Toyota 'long life coolant' (Red) or what I use is Nulon Red Long Life coolant which is an OAT based coolant.
 
If you do switch over to Red/OAT coolant (and you should) make you properly FLUSH the whole system out with water/rad flush first, as mixing the Red and green coolants apparently will sludge things up.
 
 
 

Thanks. Any specific brand of radiator flush? Also as I will have the rad out are there any tests that you guys know of as far as checking for blockages in the system?

I think most will be fine. Mine had green in it but I can't remember if I used it or not. The one I had here was Techtaloy Flush I think.
