RX7 - do a search for the specifics... but from what i remember...
they have a thermostat in side of em... and the fittings are too small... soo you gut the thermo and weld in AN bungs... and then have it ultrasonic cleaned...

Go to BAT Inc and get a new one....and use a thermostat.

No but by the time ya do all that stuff, you coulda just bought a new one that fits, needs no cleaning and has the right sized fittings.....
Kinda like reusing a condom.....

(never thought I would say that)After its all said an done you might as well get a new one. I would feel better knowing that my freshly rebuilt motor is being cooled by a NEW, RELIABLE, oil cooler, not an old, unknown condition, and after its done modified oil cooler...but what do I know??

LOL - i beg to differ tho, albeit you make good points...
depends on the NEW cooler you purchase....
but RX7 coolers are as cheap as 20-40 bucks on ebay. figure another 20 for the threaded bungs you weld in and 50-150 bucks to have it cut/welded/sonicleaned.....
I have an rx7 cooler here somewhere... nice piece. i ended up using a setrab that i got a killer deal on...
how is it different than re-using the engine mounted cooler on a /6 or a /4?? and i bet you didnt have yours ultra sonic cleaned when you rebuilt your last motor

Damn....
You got me on that one..... BUT!!!! I am not having chunks taken out of the coolor and new pieces welded on either.... Touchet!!!! (dumb french cant spell)

any competent shop with a tig can do it. but it has to be pressure tested....
aircompressor and sumberge it
its probably cheaper than you think.
RON S made his a bolt together unit if i recall - uses it to cool his 3.6

Haha...now thats something I would NOT trust myself with. If I was going to modify an oil cooler to cool that chunk of money...aaahhhemm...engine... I would leave it to the pro's... But just for comfort, if you could spend an extra..say 30-40 dollars to buy a NEW cooler with a WARRENTY would you take it or would you go through the trouble of getting all that work done on another cooler and TRUST it?

when i find all my parts for gizmo....i think i will split for a new one....plus a thremostat...
but if you have a rx cooler in your possesion.....for twenty or thirty...and money is an issue....use the damn thing..and get that six on the road....
i don't know how many degrees i lose by running refrigeration copper through the longs....but there is another idea...to chew on

So I should'nt reuse my condoms? 
My "junkyard" RX7 cooler($15) has been working great X 5 yrs. and my 3.0L has had no problems........ My memory may be failing me but I do not remember welding on new fittings....I adapted A/N fittings directly. I took the lines down the drivers side...widening the existing holes. If you want more pic's let me know.
