hey i have a complete turbo kit im about to put in my 94 LS...but what parts should i replace or upgrade before installation of the kit...THANKS GUYS!

 

i mean engine components...such as head gasket...etc....thanks

 

It all depends upon what's worn out. Give it a compression and leakdown test, if everything is good, then don't worry about the headgasket. It wouldn't be a bad idea to replace things like the timing belt, but even so, a lot of people don't do anything before they put on a turbo. If it were me, I'd give it a full tune up, replace the belts, and check everything two or three times just to be sure.
