Will I need an upgraded Alum. one next year or did the old ones work pretty good back in the day? Just planning ahead. Which brand, if I need to buy? Frank Todaro Member Region: Ohio Valley Region Car #: 35 Year : 1999 Posts: 170 Status: Offline posted         I cannot tell you if you really need the aluminum Rad or not, I have one and it works fine. my first one was the Koyo its pretty good but pretty expensive. When I toasted that one from a wreck, bought a Godspeed on EBay and its about 100.00 less expensive and works well. -------------------- Frank Member: No Pain Racing B Wilson Gold Member Region: Oregon Car #: 68 Year : 91 Posts: 2359 Status: Offline posted            yes, you will want to upgrade. Koyo 53MM or Sprigfield Dyno Rad. -bw -------------------- Bruce Wilson 2010 Oregon Region Champ 2010 Monte Shelton Driver of the Year 2010 25 Hours of Thunderhill E3 and Under 2 liter Overall Champion Oregon Region SM Class Advisor Terry Whitlock Member Region: BUCCANEER Car #: 23 SSM, 36 SM Year : 1992, 1990 Posts: 136 Status: Offline posted         The Panic Motorsports team has had good luck with the Mizu Radiators at the bargin price of $240.00. Battle tested at VIR 24 hour race http://yhst-76310268609575.stores.yahoo.net/mizuradiators.html -------------------- Terry Whitlock Scottie Member Region: WDCR Car #: sm 19 Year : 93 Posts: 199 Status: Offline posted         I have had really good results with my cxracing rad. It is basically like the koyo. 53 mm, and comes with a cap. I believe it was 150 duckets. -------------------- How do I fit this ls7 into my mia... nevermind. Keith in WA Pack Fodder Region: NWR / Oregon Car #: 88 Year : 95 Posts: 2000 Status: Offline posted         The OEM auto radiator does a decent job cooling. We ran it for hours straight when it was mid 90s at the track. We tried a stock manual one that overheated early in practice. On the other hand, we had really long straights and it was a chump car race so not much drafting. It's nowhere near as efficient as my big Koyo but we were limited to what we thought we could get away with. -------------------- Keith Novak (Will work for tires) TR6 Member Region: Southwest Car #: 500 Year : 2002 Posts: 179 Status: Offline posted         +1 on the CXracing aluminum radiator. I have been using and abusing it in the scorching Texas heat this season and it has held up perfectly so far. And less than $150 shipped. -------------------- Greg H. 2002 red Miata #500 Denton, Texas Steven Holloway Blue Eyes, Aquarius, hates being squeezed to the grass in SowDiv! Region: Lonestar Car #: 97 Year : 91 Posts: 740 Status: Offline posted         +2 for the CX radiator. Temp stays at 192 with the stock thermostat regardless. Even my oil temp has been lower-205 instead of 220. -------------------- If you can't fix it with a hammer, it's got electrical problems. D.B. Cutler Huge Member Region: Detroit Car #: 5 Year : 1991 Posts: 1029 Status: Offline posted         If you are down south, I'd say you need a larger radiator as 1.6Ls don't like heat at all. I have the big Koyo and it's been great. martinatlanta Junior Member Region: South East Car #: 73 Year : 1992 Posts: 3 Status: Offline posted         Thanks everone! good advice..
