Front engined Corolla and mid engined mk1 MR2 have the same pump. I wouldn't worry about it and that rad looks fine. The cooling pipes (if run under the car) will also provide extra cooling. A smaller pulley may cause cavitation at high rpm so I'd avoid it. If you're going racing then a larger pulley would be better to slow the pump down. Just make sure you can bleed air out of the rad.

the biggest restriction in a cooling system is the thermostat and it is designed like that and the worse thing is the pump cavitating because of to much pressure caused by restictions but we are talking about such a small car so the pipe length will be short and the larger radiator will be less restrictive than the stock one its a it might work situation it might not

I am still questioning it as well. The good thing is.. I can mount an electric pump almost anywhere. So that's a plus!
This car has many weird available space unlike a mini.

Hey guys,
I found another radiator i have a question on. Double pass 2 row
This radiator is for 600cc mini sprint racers. The radiator is 1.75" x 10" x 18"

What do you think? enough?

Unless you have knowledge in Heat Transfer and can calculate everything, it is a bit of a "suck it and see" situation.

When I did my cooling system I just looked at it basically like this. I have a 2000cc Vauxhall engine, which say puts out approx 160hp. The MPI Mini rad I had fitted right in the grill opening at the front, but this really only cools a MPI Mini say 90hp approx. I had very little room, so a side mounted rad in series was needed. I chose an Yamaha FZR 1000cc bike rad as this combined with the MPI rad should then have enough cooling capacity for the 2000cc Vauxhall engine. This has worked out fine with fans on both rads and an adjustable thermo fan switch. All bits were bought for very little.

If your cooling an engine of bigger capacity than say the rad you intend to use, then I'd say there could well be a problem. 600cc rad to cool a much bigger engine doesn't compute to my mind. Just to finally add that I checked my water temps with an infared lazer thermometer before and after each rad and if anything my series radiator drop the temperature a little too much.

My 1.6 Toyota 4age is cooled by a Nissan Micra 1.3 Rad (which measures 14.5" x 15" x 5/8"). The Nissan is around 75bhp, the MR2 approx 130bhp. The temp gauge used to sit in the middle of the gauge in the Toyota MR2 that the engine came out of. In the mini, the temp rarely reaches half way. You also need to consider that your rear mounting the engine, so what used to be the engine bay where the rad will be is now a much cooler place with the engine gone. My rad sits right next to the bare exhaust manifold. I had a problem with overheating when I first built the car as I used a second hand rad from a scrap yard. The rad was corroded so it wasn't as efficient as it should have been. When I fitted a brand new rad, the problem was instantly solved. Like Birdman says - its a 'suck it and see' situation. Personally, I'd go with the mini sprint rad.

Found another option that i think might be worth the money.
Yes.. chinese.. but i have had good luck with chinese radiators.

185 USD incl expedited shipping.
Size is 11" x 17.5" x 1.5"
Much more affordable

There are a few people running the standard mini size radiators on engines much more powerful than yours, so I'd say you'll be alright.

However as Birdman said, this process is all trial and error

Bahh..
Got the radiator and its 2" thick.. They told me 1.75 and its not. What is sad is the fact that i need that 1/4" so i can clear my radiator fan.

I realized.. the front valance of the carol is held on with foam glue. I seperated the foam and pulled the front grill/valance away around 1/2". Next i am going to relocate my support beam upwards and this will allow me to clear the fan and we should be good to go : )
