TII radiator vs. N/A radiator
I hauled *** to work this morning, opened up my hood when I got there and my radiator had a nice crack in the top of it. I've been using the na radiator, and seeing as how I have to get another one it might as well be a TII one. What I'm asking is the TII radiator any better than the na, want to know if I should just get a nice aftermarket one if it's not.
Thanks, Tony

Don't bother with the oem radiator you can pick up an aftermarket performance radiator that's all metal and performs better for less.
My original radiator split it's top 2 months ago, I bought a 2 pass radiator that was about $240, my local Mazda dealer wanted $1200 for an OEM radiator.
Also I think the N/A and TII radiator are the same part #.

I believe you'll come to the conclusion that the turbo and non-turbo radiators are the same for a manual car.
But buy a KOYO. I have one and am going to buy another. One great radiator for cars in Texas or the Southwest. It makes a big difference in the summer.

Your wrong, all manuel cars turbo or not had the same rad. The auto rad is differnt. the extra capcity you see for the turbo is from the coolent going to the turbo. That "additonal cooling on top of the motor" you speak of is called an intercooler, and I assure you it doesnt contain coolent...

Did you not read the link? Did you not notice the capacity differences?
Coolant capacity:
Turbo 9.2 qts
N/A 5 speed 7.7qts
I didn't pull this out of my *** people. Why are there people telling me I'm wrong on this one? Where's icemark when you need him? The radiators are thicker on the auto and TII. Are you trying to say that extra 1.5qts is chillin in the turbo itself? Wouldn't it make sense to make a higher capacity radiator when more coolant is needed?

Sorry, but I own and work on both non-turbo and turboII 1987, RX-7's......and they are the same animal. Plus....look at the site I left a link to for the part numbers. By the way, a KOYO is an excellent replacement for the stock radiator. A true bolt in, no fabrication required install.
Also confirmed by an expert from another part of the planet in a post above.
