Am planning turbo and pump mods on my 95 160hp auto, to hopefully get 350+ hp. Would it be good peace of mind to "O" ring the head, or would it be a waste of time at this level? My useage will be heavy towing.

 

u dont need to do anything except install some gauges...get a 100plate and some gov springs and u'll be hovering at the 300hp mark already

 

Would that be with the stock turbo or with a after market turbo? If its with the stock turbo will EGTs be an issue?

 

with any heavy towing you need gauges. trans temp, egt, water temp (I like), boost is always fun to look at.

Bypass the wastegate, on the stock turbo, a plate, gov springs, valve springs for an exhuast brake , and maybe injectors at some point.

No need for oringing the head.

If egt are a problem get a water/meth kit and run straight water when towing with a small jet, it will suck the heat right out.
