"What's your radiator/intercooler setup like on this? I'm assuming the radiator is below the intercooler? " Brandon, the radiator and intercooler are the factory ones from a 2-wheel drive Sierra Sapphire Cosworth. Yes, the radiator is below the intercooler, I cut the radiator support panel wider, and converted the headlights to only two with air intakes to aid cooling. I also used the smaller exhaust manifold from a 4x4 Cosworth Sierra and boost hoses and notched the sump at the front to clear the cross-member and steering, adding 'wings' on the side of the sump to make up for loss of oil space. If you are considering the same swap you are welcome to PM me any questions. I would say that there are probably more modern, lighter engines now which would give similar power, but I already had this engine. Just to add, the non-running L20 engine that was in the car has gone to my friend over here for his Bluebird coupe, so it hasn't gone to waste : ))
