The V6 Avenger always needed more power because that horrid A604 automatic transmission would not let the engine do its work unless manually shifted. The problem was not so much horsepower but torque, literally too little too late.

The 26% improvement and slightly lowered range offered by the 24 valve 3.0 6G72 seems barely worth the expense, but the 55% gained from the 3.8 6G75 certainly is and should turn the Avenger into a good sport in the real world the Stoplight Grand Prix.

I have seen thorough description for swapping the 6G73 for the 24 valve 6G72. What I would like to do is combine a Galant 234 HP 6G75 to the existing transmission with available performance upgrades and re-flashed TCU. My question is whether the 3.8 is the same relatively straight forward swap as is the 6G72. I'm guessing on a larger throttle body and porting work at the intake manifold. Otherwise....what?

 

There is the exact swap going on , it's not near as straightforward as the 3.0

 

my 2.5 is jammed in there pretty good...good luck fitting a 3.8. my guess is its not even worth it. if i were you id throw a gsx swap in it

 

Can someone give information about 1998 Dodge Avenger engine.

 

What would you like to know?

 

can you swap the 2.0 with the 2.5 and if so is there alot of work to do it?

 

It's an extensive swap and really not worth the effort

tranny won't work , axles won't work motor mounts tranny mounts computers and wiring harnesses all need swapped

you'll spend more on parts then the cars worth

 

Thanks that's what I was wondering. Do you know why the 2.0 is $1000 more than the 2.5

 

What do you need ? Short block ? Long Block ?

 

was wondering will a 1998 dodge avenger 2.5L work in 1997 dodge avenger it had a 2.5L in it
