power wise on a mostly stock engine? besides nos

 

A supercharger.

If thats not the answer you are looking for then probably longtube headers, since you already have a cat-back.

 

how hard is header install on lt1? motor is deep in their, i want heads/cam but aint got the $ right now

it has a stock CAI right? no need changin that, do u see any diff. if u un hook the hot coolant running thruogh the throttle body ?

 

Well, I would say a 100 shot, for 500 dollars you have an extra 100 horsepower, if you want to do it that way....

 

header install is a b****, but well worth the trouble-get some friends to help(small handed ones)-while you are there,change plugs and plug wires-I would go with Hooker LT's or AS&M.The AS&M are not full length,but do have 1 3/4 primarys but are a little pricey.

 

Headers can be anything from a breeze to a pain in the butt to install, it all depends on which kind you get. The best bang for your buck headers are Hooker LTs.

A CAI is not a bad thing to do either. You'd probably see the same difference installing a CAI as you would headers because the stock airbox/airfilter is just as much a restiction as the stock exhaust manifolds. Plus a CAI takes less than 30 minutes to install.

 

i have 93k miles...would be ok? 6 speed...would i run into problems with stock engine components with 100 shot ?

 

Stock cai? From an aftermarket cai unit you're likely to see 8-10 horsepower, also I would do the coolant bypass it's been dyno proven to add 7 at the wheels.

 

Headers aren't hard at all to install really. It is just a little time consuming. I guess the difficulty is based on the brand of header. On the CAI LT1's don't have a stock CAI you need to buy one they are approx. 175-200new. Also do the TB bypass you don't gain hp you prevent the loss of hp as the car warms up.

 

I think that all depends on ur driving style and how often ur spraying. Plus, every engine is different of course.

I have head of people spraying on engine with 150k plus and running some great times, then again i have seen people spray on a 56k engine and throw a rod.

 

Waswa, you are crazy if you think you would see the same difference between CAI and headers. I couldnt barely feel anything with the CAI. Headers were very noticeable. It is definitely a good mod though but buy a used one IMO.

 

I can't quite tell if you're joking or not.

 

Headers! all the way! even with a stock Catback, its the biggest gain other then NOS or SuperChrager for an M6

 

i've seen the dyno sheets that say that too, but a dyno can vary that much without making any changes, and turning the car off long enough to do the mod probably cooled it off enough to make that difference

 

def. longtubes? or shortys?, and used headers or CAI?
