Hmm didn't realise TD did cams! Defo worth getting an Alloy Civic rad for peace of mind on the cooling side, mine was brilliant for track temps, was well below 80c when I was on track (90c for the fan to kick in)
Awesome I get comments about my cars sometimes, but a vintage classic car owner started talking to be about Jap imports when I was in the GT at a fuel station and got talking about Starlets and old school Toyotas to a Toyota technician who drove into the dealership in a mint AE86
If it's ported properly it'll be good for 1 bar Personally wouldn't risk running any more, but you'd definitely see a gain on a tubular manifold, worth getting if you're sticking with a CT9/Hybrid
