Any new radiator options?

I think it was done many years ago, around year 2000 time frame, and that is based on a service invoice I got with this car showing the replacement of 8 spark plugs. but it is how I got the car.
I'm concentrating on the drive-ability issues first, then I'll tackle the cooling setup and front tub restoration later.

I had some radiators built to put in place of oil coolers and ran a 6 core center rad and ended up switching it to a renegade hybrid unit, I installed a different fuel cell and wasn’t concerned about spare tire. All my hoses run through the rockers and I run a electric water pump, to fill system I use a 5 gallon bucket with a pump submerged in anti freeze and pressure to bleed system.

Why did you switch to the renegade hybrid style?

What kind of radiator setup did you run before, and what were the problems with it?

I’m currently fitting a modified Jeep radiator in front of the tub, but with an air duct that’s similar, but larger than this.

I’m also going to be running a stock internal Subaru 3.0 flat-6. One of my strongest design requirements is that factory gas tank is not altered and I retain 100% use of the trunk.

I am running a aluminum block 350 with TwinTurbo‘s, no intercoolers and meth injection To cool the charge. The first set up directed air through radiator and out the side aprons to the wheel wells and that air flow was not enough so fender radiators were added. It helped but still not good enough. I was wanting to keep the tank but it couldn’t flow enough fuel, I actually cut the tank up for the lower pan and had that installed on the first set, and installed a different fuel cell above it.

With that shroud pic where is the radiator going? You have a front shot, of how the radiator and shroud work together?

Oh ya, forget the trunk that’s what the back seat is 4��

I think I might have found a perfect radiator. I was going to use a Jeep Cherokee radiator as some have done. But I would have to shave about 50mm off the bottom to clear the lower valence, and notch the side tanks to clear the bumper shocks.

Turns out the Renault Alpine A310 has a 720X220mm radiator. This size fits PERFECTLY in front of the tub, where I'm making the cooling duct.

They're super cheap also, only $200 USD, and 56mm thick core.

The Jeep one is still a bit more core area, but the Renault Alpine radiator can evidently cool a 300 bhp turbo V6 just fine, and I'm only planning on about 260 bhp.

It certainly save a lot of time using the Renault radiator.

What kind of fans will you be running?

After some measurements, I found that three slim 8 inch fans will work well, like these

I already ordered this radiator, should be here in a week or so. Then I’ll make a wooden mock-up and use that for the fitting.

The radiator arrived today and I did some test fit ups, I think it will work well.

Here's another radiator option for side, fender mounted radiators.

The 2003 to 2007 Honda VTX1300S motorcycle Radiator.

The radiator core measures 7 inches by 13 inches. The tanks on the end are 1.5 inches by 7 inches.

This would be a perfect size to fit in the front fenders.

What else is great about these, is they come with a rock-guard grill and a fan shroud. It's all there.
