Just as the title suggests, what are all the bolt ons really? Its hard to get a definite list. Im a college kid here, and Bolts on are the only thing im seeing in my future for the next few years, but after intake/exhaust, im out of ideas. Help me out.

 

cold air intake
maf sensor or maf ends
airfoil
throttle body
underdrive pulley
electric waterpump
roller rocker arms
computer tune
fan switch
shifter
skip shift eliminator
aluminum drive shaft (1le or ls1)
gears
lower control arms
panhard bar
sway bars
springs/shocks
strut tower brace
sub frame connectors
torque arm
torque arm bushing
headers
off road pipe
cutout
Electric plate for cutout
catback
true duals
high flow cats
o2 simulators
computer reprogram
roll cage
larger brakes
braided steel brake lines
line lock

 

um.....you forgot something......lol (thats a pretty comprehensive list)

you can also upgrade your ignition system (either an msd or crane box, or the delteq system)

 

coolant bypass
ram air
removeal of emissions stuff

wieght removal stuff
knock sensor

Maybe a better question would be, "Worthwhile bolt on's."

Don't waste your time with a MAF or a larger TB unless you are making serious HP. Also, the TB bypass is a worthwhile free mod. Underdrive pullies are good for about 5 maybe, but why would you want your electrical system and A/C to be comprimised for only 5 ponies? Air foil may give you 2-3. I've got one because I found a good deal on it. Couldn't feel the difference. All the other mods are specific to the goals of your car. I'm just trying to save you some $$ on stupid mods.

 

well every little bit adds up
best three mods are
cold air intake
headers
catback exhaust

 

Agreed.

 

...and gears for some, especially A4's with the 2.73's.

"but why would you want your electrical system and A/C to be comprimised for only 5 ponies?"

i personally NEVER saw a problem with either charging or AC with my underdrive pullies on my LT1, and i havn't seen any problems on my LS1 either.

noticed a bit of a drop on my old 87 Iroc...

 

That's what I am looking at doing. I also want to get ahold of an aftermarket intake elbow as well.

 

i got the 1le intake elbow because mine broke and it was the cheapest one out thier..... thats about the only reason to get it

 

adj. fuel pressure regulator as well

 

Anybody know the best bolt-on only times for LT1 and LS1 cars? I was curious if anyone had actually taken all the bolt-ons to the limit without digging into the engine. I would think at least LS1s would be able to get 11s w/ drag radials?

 

they have done that in a gmhtp mag. they were all 11-12 sec cars
some of them have had alot of lightening done to them. thats a great free mod that does wonders

if i remember none of them were using bigger than a 1.6 rr
i know they have 1.7's out thier that fit, just something to think about
