UPDATED 2.4L Performance Modification List
UPDATED 2.4L Performance Modification List
Intake: The stock air box is highly restrictive. Freeing this up would provide more air for combustion and increase power output
- Cold Air Intake
- Short Ram Intake
- Intake Manifold
Exhaust: The less restrictive an exhaust setup is, the more power will free up from an engine. Our 2.4 stock exhaust system is decent (has 2.5" piping), but it is restricted by the header, cat (in the downpipe), and the exhaust section from rear wheel back (which becomes 2.25" piping and has a restrictive muffler)
- Header (Exhaust manifold)
- Long Tube (high-end gain)
- Mid-length (mid gain)
- Shorty (low-end gain)
- Turbo (for turbo applications only)
- Downpipe
- Catback

- Transmission Tune
- LSD (Limited Slip Differential)
- Quaife
Tuning: Our stock engine tune is rather conservative. Tuning parameters like power enrichment delay, air to fuel ratio, and spark timing will result in decent horsepower gains. Tuning after installing bolt ons (intake and exhaust) will further bring out the potentials of those modifications

- Canned Tune

OK I think I got everything that wasn't added from the last thread. If you see something missing just post it up and I'll add it. Also if you have a video clip or picture of your exhaust that isn't already up please post the link and I'll add it.

try and get some brands for the STS
JBP has stage heads
LS2edit for ecu tune
for nitrous any of the brands, Zex, Vemon, Holley, etc. etc.
also Bassani makes a cat-back.
I know there are intake manifolds as well.

Added and they also make a cat-back exhaust system too.
Yes they do, added them
I can't find Bassani's cat-back on their website. If you know where I can find it post the link.

I was waiting for you to post cause I couldn't remember the who made the procharger kit lol. Its been added and I moved trifecta and I think I'll rename it also, so not to confuse people.
for short throw shifters you can add that we can use the same ones made for cavys.. i have one..made a thread also...
