Added some stuff. Come on guys I know there are build kits for the auto tranny out there help me find them please. Thank you.

 

what about pistons and connecting rods?

 

I have a Stage 2 on my cobalt and midrange does seem stronger as well as response.
Next time theres a dyno day here if I still have the stage 1 and it hasnt sold by that point im going to do the 3 dyno passes for 75 bux and have the first as a baseline run then run the stage 1 then the stage 2.

 

that's a good deal most shops around my area charge about 100.00 an hour for dyno time...

 

last time we had a meet at one of the local shops they ran a 3 for 75 pass.

 

Added what I found.

On another note do cams have to be specific to the 2.4L or can we use aftermarket cams designed for the L61,LSJ,and LNF engines too?

I asked because I came across this

http://www.zzperformance.com/cobalt_...1124&catid=143

It doesn't specify which engine(s) they can be used on.

 

they have to be designed for the 2.4 and those are probably for 2.2's

 

I hate when they state its for the ecotec engine but doesn't say which one specifically.

 

if any of you guys need a clutch... lemme know im trying to get rid of one i got =[ quiicklyy

 

Alright I have a question for this...

Jets plug in module for the 07 2.4 is the same as the 08 2.4 same part # and everything hell the ones I have were even used on an 07 2.4 before they were installed on my car. So is it possible hptuners just hasnt updated or checked the 08 computer yet? Now yes I know how these things work by changing the signal after the computer decides what to do.

Because honestly the jet module seems to make a decent difference.

Just food for thought.

 

Hmmm interesting seeing as the 2008 Sport uses the same ECM as the 2.2L. As far as I know hptuners hasn't unlocked that ECM yet.

 

What about the cti header and down pipes?

 

Got a link to them?

 

Yea they have a midlength header that is also a step header, downpipes, a catback, and the over axel pipe (gets rid of that 2.25 part and makes it 2.5) great for a cheap alt to a catback
