So the cost to fully rebuild a pre 2001 6.5 locally is about $4,000-$6,000. I was thinking to myself... Heh, I already got $50,000 in my K5blazer, why not another $5800 for an Optimizer NAVSTAR? So I did it... I guess I’ll just sell the surplus of parts and motors I have and use that money to get caught back up on this new purchase. Smart move? I think so! I already made $1,200 in parts that I picked up from a member and am about to make another $2000+ on a 6.5 I am almost done refurbishing.

I thought about a Cummins swap and had to also consider that cost, modifications and additional weight that is not good for Rock Crawling and off-road.

So what water pump, coolant cross over, IP, intake, turbo and exhaust manifolds should I use on the Optimizer?
