Bolt Ons
 

i was always wondering what full bolt ons were, well moreso if i could get a solid list that i could work off of.

i have heard

Intake
P&P throttle body
Electric water pump
underdrive pulley * i've heard mix reviews if anyone can clear it up*

The definition I'd give is modifications that do not force you to break a fluid seal (as in gasket).

everything you listed is a bolt on...headers and exhaust, lid, fuel pump and injectors

Headers, full exhuast, Electric water pump....

anything that isnt internal to the engine is what i consider bolt-ons. everyone has their own little spin on what they are though.

-lid
-throttle body
-ram air
-intake manifold
-underdrive pulley
-clutch/converter
-ewp
-headers/y/catback
-lighter driveshaft
-gears

I'm sure there's a few other little things

The most common accepted use of "Bolt Ons" or a car thats "Stock Internal" is that no mods can touch the engine oil. This also, of course, assumes that you are naturally aspirated.

LT1 land allows roller rockers...

so do the lsx lists

Depending on what engine, bolt ons also include simple things like

plug wires
coil(s)
ignition module
distributor
!EGR
TB airfoil
TB spacer
NOS
