I was making a subtle point, In my experience the 4 cyl are not prone to overheating. Specifically they came from the factory with a decent cooling system.

However like most aluminum head engines they are not very tolerant if it happens.

I guess that was my point too, radiators get plugged up, water pumps, hoses and water jackets fail or get plugged up with junk and the engine then is at greater risk than most to crack a head. I had an old Isuzu trooper with the same problem. Just sayin, Turbo conversion aside, the V6 engine is a preferable choice for me anyway.


In that respect the V6 and the 4 are at equal risk to an overheat. However the 4 cyl heads are more likely to crack when abused and the both will warp on a severe over heat.

On the positive side new 4 cyl heads are easy to come by. Besides that silly point, as you pointed out the V6 is a better stock setup. The only weakness on the V6 I have seen is the front pulley. Perhaps my next build will be a four valve V6 SWB turbo.

I ended up swapping in a lot of V6 chassis parts on mine. Starting with one almost would have made sense.
