We shortened up our dual pass radiator, and made it stockier, 2.5″ thick core, so that we could put a 21×2.5×3″ intercooler core on the top of it. Now we can add a condenser to the front if we need to, or tuck it all the way under the core support and make some room for that 1.8t log manifold.
We should have this ready for shipment by mid to late February, we are sorting out the last bits of attachment points, testing outlet sizes and making piping kits for 1.8t and TDIs
Keep your eye out for a purchase date!
So you’ve installed your new mk4 powerplant into your mk1, now you are left with plumbing it in. Some swaps (vr6 specifically, the TDIs dont fit well either.) require you to modify the radiator, and finding stock hoses that will work can be a scavenge-fest.
We have used a stock mk1 rabbit radiator flipped upside down, then you have to cap the overflow port, and it wants to leak eventually, not to mention that your temp switch is now across the engine bay and in the way of everything you just installed..
Soo… we went looking for OEM options, found a dasher radiator that works pretty well, unfortunately the aftermarket support for Dashers is very small. There seems to be little to no stock of the replacement dasher radiators anymore. Leading us to our natural course of action, make something that works the way we want.
In about 1-2 months, we will be stocked with a new radiator for your swaps. Fully tig welded endtanks, no plastic all aluminum construction coupled with the dual pass design will help keep your rabbit running cool. Stock mounting pins and core-support mounting tabs are in place. We also have removed the overflow port as most mk4 based swaps have a port on the motor or in the factory hoses.
These will also work for those who want to run carbs or ITBS and are using some sort of an overflow container.
