Thread: Upgrades.

i just made a cold air intake out if abs pipe and a 6 inch k and n filter i led it over my pcm and made cut a bigger whole threw the fender wall for more air to get to the filter. i also put a Helix td spacer in and a 3800 tuned pcm. the car feels so much better and feels like its got more balls then stock. any ideas on what i could do next for more hp and perfomance? i already have a high flow cat converter.

They're going to tell you to read the Safely modding your 3800 thread just warning you

Take out the tb spacer and put headers on it.

would i have to re tune my pcm for new headers? and weres the safly moding ur 3800 thread at i wish i new about that one lol

no you wouldn't have to.

can u give me a linkl to them. im interested

and is it only the heads i change not the pistons or anything? just a drop in part? what would it do for my car?

^^that one. as for headers, they're bolt on. remove exhaust manifolds, bolt on headers. another mod that's pretty easy to do and has a good power increase is higher ratio rockers. 99% of people will tell you to top swap and throw a supercharger on. i am the 99%.

if i top swap what would i need and i know id have to retune my already tuned pcm wont i

hpw r theses heads from zz?

supercharger, lower intake manifold, L67 heads, couple of pullies, idler standoff, L67 balancer, L67 throttle body, L67 MAP sensor, bypass valve harness... think that's it. and yes, custom tuning

Ummm, research.
