What is the difference between Grand Am SE1 & Grand Am SE

The motors are the same on all the Grand Am models. The GT's are rated a little higher due to the "Ram Air" intake but it really doesn't make a difference.

the engine is the same the only difference is that the gt goes up to 140 m/p/h and the se doesnt

False the grand am's are all limited between 115 and 120

And yes all the engine are interchangeable but if it had a four cylinder first you'd have to get a the transmission for the engine

I have a 2001 Grand Am Gt and it actually goes up to 140.... I also own a 2004 Grand am SE1 and it tops out at 120. The GT is built lighter and lower to the ground and comes with Ram Air which is why it has a higher top speed. I do prefer the SE1 however because it is a smoother ride and has cloth bucket seats instead of leather bucket seats. That is just opinion though.

False I’ve had my grand am gt up to 142 mph before if you have a pre 2000s there is no speed limiter

Also my gt has cloth bucket seats

you are all wrong the grand am is a basturd car arriving from the grand prix and the trans am
