mtnickel Posted October 8, 2012 Share Posted October 8, 2012 (edited) Looks like this might fit the bill for us RB guys.http://www.ebay.com/itm/ALUMINUM-RACING-DUAL-CORE-2-ROW-COOLING-RADIATOR-86-87-COROLLA-AE86-4AGE-JDM-/221065284508?forcev4exp=true&forceRpt=trueFor those that can't view when that link expires: it's an ae86 rad. Mark Update (Feb 2014). Finally got around to installing this. I'd say for the budget it's a pretty good option. I this into it: $110 - Rad $7 - 1 3/8" pipe ends to be welded (or JB welded) over-top of the 1 1/4" outlets $5 - Stock toyota rad top brackets. I forget the model but some late 80's or 90's toyota. Cresida maybe?. - Lower rubber mount from random car with rubber donut and hole (with $5 above). Here are the parts in question: the one Rubber donut on the left was the proper toyota one, but all the toyota mounts were welded to the chassis so I couldn't pull them. The one on the right has a match that isn't seen here. The hole was too small to fit the bottom studs. To enlarge it I took a Pulley bolt that was the right diameter, heated it up red hot with a Oxy/Ace Torch and ran it into the hole. Worked like a charm. Otherwise it's difficult cutting rubber. Dimensionally it fit like an absolute dream. First I checked how much hood clearance I had using cardboard. Once I had the rad up though it was clear that there was over 1.5" of clearance so I took the cardboard off so it didn't get in the way. The upper support is a tube so I couldn't weld a nut on the underside. I resorted instead to drilling all the way through and welding studs(bolts) to hold the upper brackets: The rubber donuts are seen below. I actually mounted them second. I jacked up the radiator until it was nice and snug to the top brackets. Then I positioned the lower and tacked them to the lower rad support. Here's how it came out: Edited February 24, 2014 by mtnickel Quote Link to comment Share on other sites More sharing options...
mtnickel Posted October 23, 2012 Author Share Posted October 23, 2012 As an update. I think I'll take the plunge on this. looks like a decent piece. Will keep you updated on fitment and cooling abilities. Mark Quote Link to comment Share on other sites More sharing options...
richracing Posted October 26, 2012 Share Posted October 26, 2012 I just checked the measurements on the AE86 vs s30 radiator, and it looks like the AE86 rad is 3" taller... That could be a problem. post pics of fitment when you get it installed. Quote Link to comment Share on other sites More sharing options...
stony Posted October 27, 2012 Share Posted October 27, 2012 The Arizona z radiator has worked great for my rb setup. Quote Link to comment Share on other sites More sharing options...
mtnickel Posted October 29, 2012 Author Share Posted October 29, 2012 The Arizona z radiator has worked great for my rb setup. This one has a total height of 16.5". I'm fairly certain that isn't too tall for a Z-car. I've seen others up over 18.75" (JTR), and the KOYO 240z rad on ebay is roughly 17.5" tall (454mm). Did you look at core size or overall height?

richracing Posted October 30, 2012 Share Posted October 30, 2012 I was comparing that to other 280z radiators, like this one... http://www.ebay.com/itm/Aluminum-Radiator-70-78-Datsun-240Z-260Z-280Z-RB-RB20DET-RB25DET-SHROUD-12-FAN-/250901727939?pt=Motors_Car_Truck_Parts_Accessories&hash=item3a6ae88ac3&vxp=mtr ...which has an overall height of 13.5". Now I haven't measured how much height I can get away with in my 280z, but i will pull out the measuring tape tomorrow. Quote Link to comment Share on other sites More sharing options...
mtnickel Posted November 3, 2012 Author Share Posted November 3, 2012 That one sits on top of the frame rails, not between like others will. I believe maximum width to fit between is about 25, but 24-24.5 is preferable. Mark Quote Link to comment Share on other sites More sharing options...
mtnickel Posted November 3, 2012 Author Share Posted November 3, 2012 Other issue is that it's outputs are 1.25" vs 1.375" (1 3/8"). I'll likely just weld a sleeve over it or something. Quote Link to comment Share on other sites More sharing options...
R3VO 3VOM Posted November 4, 2012 Share Posted November 4, 2012 I just used the one from mckinney motorsports. Very well done and can be ordered with an electric fan that plugs into the stock wiring. Quite a large one. Quote Link to comment Share on other sites More sharing options...
mtnickel Posted November 5, 2012 Author Share Posted November 5, 2012 The point was to save costs. The mckinney one is what...$300-$500? This was roughly $110 shipped, $30 for a Volvo fan and relay. Add in an aluminum pan to build a shroud a couple brackets from a junkyard, and I should have a pretty good cooling system same side for under $160.

mtnickel Posted November 6, 2012 Author Share Posted November 6, 2012 The only thing I'd worry about is quality really. This is a legitimate concern figuring ebay. That said, I've been quite impressed by most of the ebay intercoolers and whatnot I've got. It's nice that it's all aluminuim as well, so if it needs a repair it's just a matter of welding it up. It arrived yesterday, and I just need to pick it up from the states (I'm in Canada). Will let you guys know how it looks in there.

richracing Posted November 20, 2012 Share Posted November 20, 2012 updates??? hows the fitment and how did you mount it securely? Quote Link to comment Share on other sites More sharing options...
mtnickel Posted December 7, 2012 Author Share Posted December 7, 2012 updates??? hows the fitment and how did you mount it securely? Looks like it's going to fit great. I'll get some pics up as soon as I can. Just got married and the house is a little crazy...plus working on cabinetry stuff for new place. This project has taken a back seat, but I look forward to getting it going asap. Fire up the garage heater and go! Mark Quote Link to comment Share on other sites More sharing options...

BobsYourUncle Posted December 10, 2012 Share Posted December 10, 2012 What are the drawbacks to just modifying/moving the top outlet on a radiator designed for an S30? There's plenty of cheap ones ebay... Quote Link to comment Share on other sites More sharing options...
