hey guys, well i was looking around and i found a 98 3.8l firebird the thing is it needs a new motor, and well i recked my 97 3.8l i was thinking could i just swap my engine out of the 97 right into the 98 with out any probmles. i mean both cars are set up for a 3.8l so they should just be as easy as swap in swap out right? the only thing im worried about is that since the body style changed that it wont fit but i dont no so can u guys help me out here

 

i can't see any reason it would not work. they are pretty much the same motor. the lt1 bowed out for the ls1 that year but i don't think the 3.8 gm motor did. you may be asking on the wrong website. most on this site have v8's

 

Its the same damned car with different panels. I see no reason why it wouldnt/shouldnt work.

 

The throttel bodys are different. Ones slanted as the other is not. It should fit no problem, gain a coulple of horses straighting up that whole intake (lid to the manifold). Also, in 2000 they swiched to Tubeler headers. Which gave a few more Horses/sound. It should fit no problem, Might as well get pace setter headers and look up abboit raceing and get some heads and intake ( The sponsered car has a stage three/ 275 hp to the ground/ some odd 300 torqe.) Look up www.firebirdV6.com Perferct site for the 3.8 and the 3.4. Some guys are running close to 450hp to the ground with a few mods.

 

A "few" mods?

A heavy cammed and stage 3 headed LS1 with all boltons through a 6-speed tranny makes 450-460 rwhp.

I sure as hell don't see a 6 pack doing that even with a full bolt on/cam/head set up. If so there aren't more than a couple of those "freaks" in all of the United States.

A few mods.
