i bought one for my '80zx. when i recieved it, one of the lower fan shroud mounts was broken off. they didn't fit right anyway so i removed the other side and then soldered on the ones off my original radiator. i had to by speed clips for the rest of the shroud mounts and oblong the holes in my shroud to line things up right. i also had to shorten the screws that hold the shroud on, or they would of touched the tubes. i had to use new mounting bolts but the holes lined up fine. i had to run a new overflow hose because my original was too short and it was a pain trying to slide the hose on the new tube on the radiator due to the tight fit. i had to grind away the mounts on the evaporator because the new 4-core doesn't allow clearance for them. i needed someone to help me hold the radiator up as high as possible in the car before i tightened it down or it sat too low and i couldn't get the lower hose on. after all that and a new paint job on the radiator everything worked fine. i bought it on sale for $220 and am very happy with it so far. it was only $30 more than a new 3-core. what a deal, just took some work.
What I have heard each and every one of you say here is that it didn't fit. Works fine but it didn't fit. MSA has had big trouble with the 4 core coming apart and busting after a year or so. Wouldn't you rather have a better radiator that fits and costs less? Try Griffin Radiator. Even custom built they are less money, made of aluminum so less weight, and much higher quality. You can direct them to put things like temp sensor bosses and even AC evaporators built right in. Search them out on your browser. I am all for MSA in fact my car is an MSA poster child but when a product is a dog you gotta cut it loose.
when i bought it i wasn't expecting a perfect fit, that's rare among custom parts. what i do expect is for it to last. i haven't heard myself of anyone having problems, and the radiator looked of sound quality. it had good solid welds along the tanks. $220 for an all brass radiator is an excellent price considering it's size. griffin can't build a custom aluminum radiator for anywhere near the same price.

Actually I've heard of at least half a dozen that have gone bad in around a year.
When I pulled mine out with less than a year on it it was leaking in 5 different places. The shop I took it to said it had a complete shortage of solder holding it together.
It's only about $40 more dollars last time I looked for the more efficient crossflow racing radiators. and that was the one that was custom made for the Z. The make fit ones are about $50 less than the MSA one.
is that gm radiator a direct swap or what mods are required? and if they make an aluminum radiator to fit a z for that kind of price, i'm all for it. i've just never seen one for under $350. could you give us some names and places to find these radiators? that would be helpful. if my 4-core springs a leak, i'll most likely just get it fixed. it would piss me off if it only lasted a year. a 3-core modine at my shop price would of cost me $190. that's as cheap a radiator as i could find brand new.
