I'm in the midst of planning and executing some mods to my car. Debating the Turbo S and Cargraphic GT Auxiliary oil cooler issue. Haven't made up my mind yet. Some well-respected Rennlisters with TT's pushing very impressive horsepower levels endorse the added protection of the GT unit, but it may not be necessary for my intended uses (street and DE's with this car). I am collecting price and availability info. What is the cheapest source of the Cargraphic GT unit? Sorry I missed a group buy in January. Thought I could find one for $1500 or thereabouts, but having no luck. I'm aware of Gert and have used him with great success in the past, and will again in the future, but after currency conversion and shipping his 1500 Euros is $2000 USD. Anyone know of any sellers with them in stock and charging a reasonable price?

Kudos to those going the way of fabricating their own units, etc., but I've narrowed my thoughts down to these choices.

Thanks
