I was going to do some work on a 96 Camaro for a relative, to try to get it up to speed. I was wondering if anyone has any pointers or helpful things to add.

non-limited slip diff.
4L60E trans
3.8 V6 engine with hyper chip

We've have done:

changed the oil (valvoline maxlife 5w-30)
spark plugs NGK laser iridium
spark plug wires (ACDelco Prof)
coil packs X3 (ACDelco Prof)
driver side window regulator w/ motor (dorman)
fog light assembly RH (used)
coolant exchange (prestone)
new abs headliner
rear shock absorber replacements (ACDelco professional, left rear is already leaking fluid after 2 months....?)
brake fluid flush all 4 wheels (valvoline Dot 3/4 synthetic)

Planning on doing:

Power steering fluid exchange, drain and fills x3-4 (prestone)
Transmission fluid exchange with new filter + lubegard (valvoline maxlife atf)
Rear Differential fluid exchange with new gasket (valvoline 80w-90 w/ felpro gasket)
another coolant flush/clean and exchange (prestone)
sea foam air intake cleaning/hot soak

Thinking about:

whole car new bushing kit (looking at ENERGY SUSPENSION318130GBlack; Hyper-Flex System Performance Polyurethane from rockauto.com )
new tie rod assembly (looking at PROFORGED11610017 )

any helpful advice or more things to replace or look into? Thanks

Its its in pretty good condition, but needs some maintenance.

 

Add pressure testing the coolant system. You can borrow the pressure tester from a chain parts store and just search "how to pressure test my car" on youtube. The 3800 is prone to failing lower intakes and if the coolant gets into the oil it will ruin the engine. The issue with the lower intake gasket was the material so if its already been done it will not be an issue in the future.

 

Do you mean the head gasket? I didn't know the coolant had anything to do with the intake gasket

 

There are two coolant passages that go through the lower intake gasket. This allows the coolant to circulate through out the block. This is very comon knowledge in the 3800 comunity.
