So here's my story...
I'm new to the forum, but I've had my 95 rs for about five years. About a year ago, it overheated on me and blew the head. Ended up being the water pump. That's when I found out that finding a 420a in this part of Indiana is nearly impossible unless you got at least a grand laying around. So the car has sat ever since.
A couple weeks ago, I finally found a motor I could afford so I jumped on it. The guy had decided to go turbo so he bought a motor that was aleady built for one. So I gave him 300 for the motor minus the valve cover (apparently the company that the turbo motor from doesn't include the oil pan or valve cover). I had to spend another 200 for gas to go pick it up, but all in all it was still about 300-500 cheaper than the junkyards around here wanted (assuming they could find one)
Before I realized that the old motor was blown, I had replaced the water pump, thermostat housing (I origionally thought this was the problem), idler bearing, tensioner bearing, and timing chain. All have 0 miles on them. So assuming nothing has frozen up from sitting, I have those parts at my disposal. However, when I replaced those parts, I somehow managed to screw up the inlet on the radiator, so now that needs replaced when i get the motor installed (i'm nowhere near good enough to try it myself). And that brings me to my questions:
Hey, I searched around with the search feature and found a lot of useful information about the radiators available for the 420a. However, I didn't find anything that specifically answered my questions. I'm sorry if this turns out to be a topic that's been beaten to death, I really did look for it.
based on what I can afford, I think my main options are stock, radiator barn's aluminum radiator, and a koyo aluminum radiator with the plastic tops. Stock, I've seen for around 80-90 bucks, and the koyo for 135, and the radiator barn for like 132.
How much cooler will the high performance ones keep my motor? Are the Koyo and Radiator Barn pretty much the same aside from the top, or is one cooler than the other? Also the Radiator Barn doesn't mention whether or not it fits an automatic transmission. Has anyone had any problems there? It does however mention that it works with or without ac. The Koyo doesn't mention ac at all. I've never heard of that being an issue. Does it really make a difference?
For the record, I have an automatic with no ac, but I'm considering installing ac if I can find the parts cheap enough after I get the car moving again.
Sorry if that was too lengthy.
Any other advice is welcome.
Thanks.
PS, sorry about the topic name, I should have thought that through more.
