I'm lookin at a 92 1 ton and just wanted to make sure they didn't choke e'm down to much, thanks Terry

 

oldy enough cali dont have any emissions for diesles here. but i do not know for sure.
if they did its nothign that cant be bumped up. thing slike pumps settings etc... the 92's that came here may have all had the 21cm housing where as others have an 18cm. both suck. jiMMy

 

Not on a 1st gen. 2nd gen 12 valves had EGR.

 

they sure did do something different to them: they charged us about $3 to 5k more for them!
