Hello all, I’m doing some thinking and I guess you could say I have a bit of writers block but for modifications. I have an 06 supercharged cobalt, I built it up with a zzp stage 2 kit, 2.8 pulley, tuned ecu, k&n typhoon cold air intake, fully built 3 inch exhaust, long tube headers with a cat delete. I’ve got a dual pass endplate, a stage 3 heat exchanger, lighter weight enkei wheels, upgraded rear trans mounts, sway bars, and strut bar. I’m still in high school and this is my first car, I love it to death I’ve put a lot of time saving and wrenching on this car and I seem to have run into sort of a roadblock of what to do next. I could put in a limited slip diff, put new coil overs (the previous owner put them on, I don’t have any issues with them), or I could upgrade my 60# injectors up to 80# and start running e85. I really don’t want to do a turbo swap on it, I know it would be faster and more fuel efficient with a turbo swap, but I feel like if I wanted a turbocharged one I coulda just got the turbocharged one. Are there any mods that I’ve missed that would give me some good gains while still keeping it what it is, I.e. no engine swaps, transmission swaps, massive projects etc. I have access to tools and lifts and such at a military base I have access to, and I’m a hard worker when it comes to getting cash to support projects, though I am by no means rich. I want to maximize my cars potential without changing the identity of the car, and essentially make the fastest supercharged cobalt there is lol. Any ideas for more mods I could do? Thanks for the input!

 

HS and a fast car...This may not end well.

 

build head and tvs next

 

Haha yep, never heard that one before but hey at least I’m the one payin for it all and I have usaa so paying my insurance is also doable

 

^This.

 

Yeah get a tvs and ported head/cams/springs.

 

Ok so which one first? It would seem building the head and such would be cheaper than a tvs am I right?

 

I’m thinking about getting a tvs, are they somewhat simple to install? They seem easy enough. Also thinking about running meth injection, since we wanna reduce as much heat as possible and also reduce that carbon buildup around the ports, best thing I can do before getting an actual port and polish job done, can’t do it until school breaks for a bit. Anyone know the best quality meth injection system? The more failsafes and alarms the better, even though I’m not really going to tune it over the top starting out, I’m willing to pay for that extra room to improve.

 

The TVS is an easy install but you will need to tune for it.
As far as meth goes there are a few options but hit me up if you are serious as I have a pump and a progressive controller that I need to sell when I get time to list them officially.

 

if you have access to e85 i would start looking at that route. you wont have huge gains with the stock blower, however the gains will be far more apparent once you go with a tvs blower.

if you want to go down the water/meth route i would highly recommend an AEM kit with the multi input controller (kit number 30-3350). i went to this kit and am using injector duty cycle to control it, it works far better than a boost based water/methanol system for a blower car.
