I'm on the hunt for a radiator, I ended up putting the A15 in the because my 1200 block was not back from the machine shop. A15 runs great car picked up 500 rpms down the straight but the cooling is now marginal. I'm using a GX 3 core which likely needs boiling out again (been 5years) so this time I'm looking to upgrade. I saw 3 core aluminum race radiators for Roadster $200, the inlet/outlet are in the right place etc. Any one try a roadster rad or now of another that will cool the car well (Yes I looked at the upgrade section) I keep the motor between 4500 & 8000 RPMs when on track and most of the time it's above 5500. Any suggestions??

I doubt you guys got them in the US,
but the radiator from a C20 vannette works a treat behind a worked A series engine.

You can't beat the N14 radiator
* all aluminum
* $79 brand new
* fits well in a 1200

See Radiator Upgrades

We can get the Vamette radiator from Rock Auto but it's $471, so that is out

David, yes the Sentra rad is good but is it an improvement over a 3 core GX, basically do we know if it will cool a built up A15 in 100+ degree heat?

It is Pulsar and will cool a 115 HP GA16DE.

The thicker versions are for SR20DE, but are $90.
