I'm in the process of taking my 80 engine out (Newly Rebuilt) Hayes Mazda Rotary done it, and installing it in a perfect condition 84 GSL. Only change is Mazdatrix Complete Header and Exaust System.

My Question is: Should I stay with the under radiator oil cooler or change it out to the under the oil filter leaking prone filter thats on the blown 84 engine.

I have both radiator and filter styles.

Any help before I make a Boo Boo.

Thanks

Past 6x RX-7 owner. All 1st Gen's :unsure:

One of the most popular mods for 83+ 1st Gens is to rip out the oil cooler and install the "old style" under the radiator type cooler. These coolers are far superior to the cost-cutting oil pedestal version that Mazda installed in the later model 1st Gen.

Radiator style GOOD!

oil filter style BAD!

I dont think you can just take out the water/cooled oil cooler...I think you wil have to change that housing..and I wrong?

Someone explain..

nope, you just take out the oil cooler, and replace it with the 80's oil filter pedestal

Yeah I just learned that going to a rotary shop...

I think I may convert mine over..

Thankyou Everyone. It worked---Ta Da---

Just so ya's know, make sure you replace the Foam on the sides and top of the Oil Cooler or it will rattle like Hell.
