Would this be enough for cooling? i have a question in reference to cooling,
i am building a 240sx with a ls on boost and of course space is very tight so i had to make some custom parts here and there, cut here and there.
well either way back to the point, my current setup with a ls1 water pump with a 160* thermo in it, and 2 spal fans i believe 2800cfm both together. and then here comes the part that kinda throws me off just because its most likely one of the one rad that will fit how i need it to fit .
its a Griffin Radiator 22x13x3

just want to hear your opinion on this setup

That thing certainly isn't very tall, but the core part is pretty thick and seems to use every inch of the height for the core. this radiator for a 240z is known good with an LS. It is wider but the actual core area isn't any taller. 2 thicker rows might have better air flow than the 3 thinner ones on this z unit

I assume you have an intercooler further blocking airflow? Where do you live? Middle of Texas or Death Valley would suck.
You know a lower temp thermostat does nothing to help prevent overheating.

Assuming the same number of rows and similar fin construction, a radiator that has two times the surface area (L x W) has twice as much heat rejection capacity. Your 22" x 13" has about 290 square inches. Compare that to a Summit universal aluminum unit at 30" x 19" - 570 square inches - almost twice the area. So, the 22 x 13 seems quite small to me. I run a 2 row 24" x 16" in my 240 (Volvo) with twin 11" SPAL fully shrouded.
While the extra rows help -- they don't help as much as folks think. The problem is that the delta-T (air temp) available to transfer heat reduces significantly as air moves through the radiator. It picks up heat (raises air temp) from the first row and then can't pick up as much from the second, row, and even less from the third row. So, the second row adds about 50% more heat rejection capacity, the third row adds about 15% more.
Given big turbo V8 - I'd want more rad.

Seems to me you'll have to cut some sheet metal and fabricate. Your car isn't any narrower than mine -- so there's some room there somewhere. The Corvettes tilted them back to solve the head room issue.
