i have been looking at hahn and zzp for the 2.4l boost kit. my ride is going to be daily driven, but i want a decent amount of power, and not have to worry about it taking a dump. can anyone advise on what kit they have, and how was it installed(by self/ shop) and how it has acted/ or if ya have had any problems. I have the dough to buy either kit now, i just cant make up my mind here, and opinions welcome. thanks .

 

I have the hahn setup but modified. the parts mechanically are great. the tune is the hard part. you better make sure you have someone that knows what they are doing with tuning. Thats been my only problem is tuning.

 

celica when u goin back to the track? im really curious to see what kinda times u put down with the new tranny man..... i wanna see if our cars can truly best the 2.0's and have u got the new tune down yet?

 

Im still having a hard time with getting the tune right. It runs good as long as its not WOT but I cant race without being WOT. Wont shift past 6k after turning codes off that were disabling the engine. Im not sure what you mean about besting the 2.o's but I have beaten a few supercharged cobalts already at the track as well as redlines.

 

i mean potential-wise...... just wanna see which of the engines would have more

 

Our tunes on the 2.4l turbo kit are great. Great driveability, great gas mileage, (as long as you are not in boost all day), and great power. No extra inj. or piggy back controlers. Our car went 11.8, I'll let that speak for it's self.
