I looked at Tracy's site last night, and can't see how he has room for his cooler to be in the right cheek area, behind the evap core.  I have to believe his engine is farther from the firewall than mine, because there's absolutely no way a stock 2nd gen cooler will fit in that location on mine. 

 

Cheers,

Rusty  (still in search of cooler)

 

 

Two factors made it possible.  

 

1.  Used the early RV-4 FP prop cowl (40" FW to prop flange) which is about 1.5" longer than current version

2.  Used the RX-5 Cosmo oil cooler which is shorter but wider than the RX-7 cooler, and has ports more conveniently located than the RX-7 cooler.  It was a gift from my brother Barry who owned the RX-5 donor car.
