I seen something similar to this in the GT section. I noticed we don't have one and even though a lot can apply from that thread to our cars also, we need a "go-to" thread for all members w/ a GS to come to for ideas on what to do with their ride next. This could also help prevent a lot of "I'm new what mods should I do" threads. I will update this thread constantly and would love for members to chime in and help make this perfect. These may not be the best prices but they are the upgrades themselves.

Hehe :wub: you didn't say no :ghey: Dax :naughty: haha j.p
Didn't want you guys to go unnoticed on this and take all the credit. I'll actually use a "*" to mark what was added by other members!

You guys did a fantastic job writing this up! Good work all the way around the engine stuff is golden. Their isn't anything you can really "add" to forced induction accept that bolt on manifold sense that's the only mass produced part :(. Hopefully soon that will change.. I would rep you guys but my phone won't let me
Thanks man, just trying to help the community :) :bigthumb:

Will add all of this man and credit you! Big thanks!!! :bigthumb:

Too bad Ripp Mods doesn't make the 4G69 headers anymore otherwise, you could put that too on the list.
Under the "Weight Reduction" section, you have "RRE or OBX Headers" and "the RRE Underdrive Pulley" but I'm guessing that's a typo.
You could put in the intake manifold for the prev generation Lancer Ralliart. It's more or less PnP.

It's time to e-Rape your ass! #nohomo
Haha I thought it felt a bit sore :squint: lol, I'll add the intake manifold, and I put the pulley and headers under that section also because they do both weigh less then the originals thus "reducing the weight" some. The headers drastically weigh less due to no catalytic converters. Also a CAI weighs less then the stock airbox. Not necessarily specific for weight reduction but wanting to give people an idea of what does effect our heavy ass cars weight lol. I'm going to reword it to make more sense now haha. Thanks tho :woohoo:
