I am now fully bolted with a GTX 250 turbo and tuned on 93 pump gas, with city driving I usually average around 24 or 25 mpg's, on the highway cruising at 80 mph I get right at 31 mpg, not bad

as the title reads

all their kit is comprised of is the Eibach lowering springs and Sonic RS struts. If you only have the springs I'd be interested in that as well, or the GMPP performance suspension

will also consider larger injectors along with it

as the title suggests, Im noticing a bad noise whenever I accelerate from a stop while making left turns only. it also makes this noise if I accelerate hard in a straight line. I've seen other posts similar to mine but without answers on other websites, it must be a front wheel drive thing. I...

Got some new tires installed recently, Falken zeix ze960. There isn't any reviews on them as they are new tires so I'll provide my input. My initial impressions: they have a much stiffer sidewall than the extremecontact dws06 I previously had on. I went from 215/50-17 to 225/45, although its a...

Had the inevitable blown PCV check valve in my intake manifold and prior to that my purge solenoid went out. I've already replaced the other two PCV check valves. I replaced the purge solenoid and installed the PCV bypass/fix kit and at the same time installed a boost/vacuum gauge and AFR gauge...

I've already got the ZZP downpipe and a custom catback, only need these two pieces. I could just make my own cat delete section, but I would really like the ZZP mid pipe

Tons of useful info here and knowledgeable people! I mostly thread lurk and soak in information, and based off of what Ive gathered, Encore rotors are a direct bolt-on as with corresponding f-body Camaro 2-piston calipers. the Camaro rotors are 300mm OD just like the Encore rotors, but are...

Looking at finally upgrading the sound system on my 2012 sonic LT and got a few questions. Ive been lurking the forums and looking at pictures and installation does not look terrible. While I'm doing the install I plan on sound-proofing the doors, spare tire wheel well and the trunk with dynamat...

good condition, local pickup only, 350 OBO. more info here: Chevy Sonic OEM 15" wheels, tires, lugs

Got some Trico Force wipers for my sonic a couple months back, about an inch larger on each blade. I've noticed on the larger blade that it "flutters" at speeds over 60 mph on the upstroke. Could this be due to the spring in the wiper arm not putting enough tension on the larger blade? Has...

Does anyone know if the RS grill has the same dimensions and the same mounting points as the grill on the other sonics? I like the look of it, hides the "mustache" with the hex pattern out in front

Filmed with my gopro hero 2 for a short drive. Mods are a Spectre intake, custom 2.25 inch cat-back with a 3 inch tip, no mufflers or resonators, and a custom tune. I think it sounds good :) I was granny shifting for the most part, maybe one of these days I'll do a 0-60 run with the camera in...

I was cleaning my sonic the other day and accidentally rubbed the end of the vacuum tube up against the radio screen and ended up scratching it (this thing gets scratched really easily, I want to put on some kind of film to prevent that) but anyway I want to remove the scratch but don't know...

How can I get one? I searched the forums on here and didn't get any info about this

Didn't have the money to buy a name-brand intake yet, so I settled for this with a tune for now (pretty much the same anyway, only this one's plastic and does not come with any mounts) I had to make the bracket that goes around the second bend and onto the frame so it doesn't wobble around as...

Thinking about getting some aftermarket wheels in the near future, have my eyes on a set of 17" bronze EV5's. I have a black Sonic hatch, what do y'all think? I read somewhere on here that if I switched to 18's I'd have to re-calibrate my speedometer, hope that's not the case with 17's

Anyone have this setup, an aftermarket intake and tune? A buddy of mine data logged my sonic the other day and we found that it runs pretty rich from the factory, which explains its rather disappointing gas mileage around town. I know turbo vehicles usually run on premium gas only, and its...
