I was more worried about durability and cooling capacity when it gets hot this summer (40C) and I'm using the air conditioning. It does seem cooler, (never goes above 1/4 scale) and rock stable, but that is also because the pretty looking single row was bad... any radiator change would have been an improvement.

It's my understanding the turbo really needs, HAS to have the twin row. The single is a recipe for disaster.

Be careful trusting the L series temp gauges, most never read above 1/4 scale. An auxillary temp gauge is the way to go as well as replacing the original L sender. ( advice from someone who has melted an EA82T without a heads up from the temp gauge)

I installed a new 2 row when I put the fresh engine in my RX. With a aftermarket gauge, the temps never went over 200f.
When I installed the TMIC and hood scoop, my temps while on the road rarely went above 140f. It was the coldest running EA82T I ever had.
The gf was complaining about riding in it as it had very little heat in the cab :rolleyes:
First thing she asked me when I did the EJ swap....Does it have heat now?

Last fall I breezed thru my RX's ea82t for a winter commuter ( just hg's,seals and head surfacing) using the stock rad w/o aux fan, it has never kicked on. With an aux temp gauge I was running 190 ish 30 thru 50 degrees. As the temps started to avg upper 50's to low 60's I averaged 200, 210 to 215 on long uphill grades, hotter under boost. fsm states operating temp at 209 +/- 15 degrees. Dont like to push it like that and as of last weekend the car is parked while I source ecu/harness waic for ej20G conversion. Should note also that rad was 200k afik and at 65-70 mph 2 hour + trips. could imagine what new rad and working aux fan would do.
