The old radiator was giving me trouble, and was corroding badly. I had it in combination with an ebay thermo fan so it was never going to work that well. I picked up a radiator from an EG civic, and a slim AC thermo fan from a mid 2000s Holden Astra (Vauxhall?).

Comparison:



I used the civic hoses cut to size in combination with the lower datsun hose. Then trimmed the fan shroud to fit on the radiator:



Mounted in the car:



Slightly shorter than the 120y rad, fits under the bonnet fine:



Also needs an overflow bottle, and some mounts bent up to stop it falling into the crank pulley. Runs cooler in traffic, yet to test it properly (Sydney summer). Was cheaper than an ebay alloy rad at $90 for the parts and I got a fan too. Any suggestions to make it even better?

Very nice, about the same size too. How did you fasten the radiator to the car? and the fan to the radiator?

The fan bolts directly to radiator if the top of the shroud is trimmed to fit around the top hose. One side needs a short bracket made up but I used a cable tie through the fins for the time being.




The bottom will not come free as it is sort of wedged into the bottom tank and also bottom hose.

The bottom of the rad itself has two plastic posts that fit into holes I drilled in the rad cross member.

Thanks for providing this info. Turns out this is the least expensive radiator I've yet to see and still is good for a 90hp engine (26mm thick version -- 60hp for the 16mm version). Much less expensive than an eBay alloy radiator. And it is almost identical in size to a B110/120Y radiator

To finish off the catch can, here's what I used. As long as the overflow hose is keep in the water of the container it will work fine

I used a 3 core version of the same radiator from ebay
was a 90aud pick up from an altona warehouse in Vic. Oz.
Think they moved to Hoppers Crossing for rental reasons.
Used it for my 1.7L G16B into a 1999 carry van.
Went from 1.3L to 1.7L with cam and lighter flywheel.
Revved daily to 7500rpm with 90mm stroke giving no issues
and temps were always very stable. Great budget radiator!

with elec. fan 3 core 32mm $110 or offer

without fan 3 core 32mm $90aud

Issue is D you need a shroud for that thermo fan (although they're available through ebay too for extra cost). And it wasn't getting hot at high RPM, it was hot at 800rpm sitting still in traffic. The temp would crawl up and the fan combined with the aging radiator was not moving enough air. Hence a newer fan with more power.

Also consider height is an issue in the 1000. My bonnet barely shut with a 120y rad. The wider A14 radiator fit fine but the one I had was in even worse shape.

Bracket example:



I like that any container can be an overflow bottle, lots of opportunity for something ridiculous (like a VB tinnie)

The early suzuki 1.3 radiator would heat up after some redline use
then idling at the lights, the shroud was the suzuki unit worked well.
I used the toyota top rad brackets which are everywhere.

Its a nice conversion though you will be more than happy as long
as you keep it filled with the good stuff. Good to see these cheap
radiators serve the budget car communities.
