I was at the wreckers, the VN commodore is a nearly perfect fit.
Call Randy at NISSCO in Bayswater and ask what he put into the ' moster red dr30 that vincent had' i think it was some sort of falcon or commodore.
If youre after an alloy one, look at the S13 range for the SR20 or CA18det. the inlets/outlets are in defferent locations, im not 100% familiar with what goes on with th FJ but the radiators are CHEAP from tawian, like less than $200 landed, off the ebay...
there are real pricey ones, and also cheapi ones...
but the fitment is near spot on too.
I have a 3 core copper Australian spec MR30 item,has inbult auto radiator cooler bult into the bottom tank. it does need a bit of a repair (stone chips in the top section of the honeycomb)
Its only worth as a spare to me for in the future, or sell it for the c0pper!!
Currently installed and running, leaks about 200ml a week.
Dunno how much its worht but fell free to make an offer. Im gatehring funds to get some exhaust mods done (the age old 'over the diff 3 inch' trick)
