quote from rx7club:
 
The stuff is great. I was one of the very first people to actually use it through Pineapple Racing. (I\'m his test subject alot of times.) As far as costs go, i think its $20+shipping.

I beleive that Rob won\'t warrenty a 3rd gen motor without this stuff running in the car. CJ

I bought mine from here (http://www.racestuff.co.uk/www.racestuff.co.uk/info.php?p=4). Seems to have gone up though.

I run the npgR, which was advised when using electric water pump.

It is also best to change over when engine has been stripped as it does not like much water ingress.

And do you just replace the AST cap with an open cap?

Quotedo you find the car runs cooler?

It won\'t make car run cooler, but Evans does not boil until a much higher pressure. Pressure is induced in a water filled system to raise the boiling point of water.

QuoteAnd do you just replace the AST cap with an open cap?

I run mine at zero pressure, but my setup is far from standard. You can run a open cap on the AST or a lower pressure one. Don\'t forget you would need to clean out expansion tank an refill with Evans.

I am using a citroen saxo pump, which you can just see mounted in picture.

The turbo oil feed comes from the normal exit point on front plate.

I could make a bracket, but you can buy cheaper online!!!
