Well, did I ask you talk about that? Not... :rolleyes:

I don't care if my car is that slow. In my Ohio law that we have speed limit for 55 or 65 on highway. Florida where you live I have seen 70 mph so far. You used be speeding freak. I know some of you are speeding freak. :p

Oh one more thing. If I decide swap them. I still use regular unleaded?

L36 yes L67 no.

lol, I guess someone could take that two ways lol.

You need to calm down (again) you're the one who opened this can of worms you do'nt see the rest of us posting" Good reason to sh-t can that gutless POS 3.1" the point I'm trying to make is if you ask for feeback your going to get it,but from what I see the 3.1 is a decent DD motor if you're not into performance the only thing for showing there's not much bling available ,since your motor is running good wait till you have problems with it to decide on a swap and a new motor is fairly expensive you could buy a good low mileage drop in for much cheaper but I woul bother with it right now since your engine seems to be fine .Chico(pops)

Palsut show your friend this picture and tell him to shut up.

This is lame discussion.
I don't think I need to point out the reliability of our 3.8 engines. That is not disputed. And we know what causes engine fires, so if you've heard about the injector o-ring issue and have an older car, laziness is what will cause your fire.

Onto the transmission:
1) on the forums we hear about transmission problems a lot.... more than engine problems. this is because most people are modding and driving around like a$$ holes, hence broken transmission.
2) if our engines had some kind of issue like other american engines, we wouldn't be paying as much attention to the transmission. it happens to be the weak spot, so why are people saying its so terrible?
3) tons of people have had their original transmission last a long time. I don't need to point out examples, but to add to it, I have 121,000 miles on my non-HD original transmission, and have been supercharged for 2.5 or 3.5 years no issues.

Thank for all the helpful tip and advice. I need lot of thinking about that all day. I will let you know official answer tomorrow.

BoostenGTP02: I emailed him a picture. He says "lol, better call a fire truck I think his engine is on fire"

Alright, I'm going say that instead tomorrow.

I have spend some time to research for 3800 engine. They are very nice and fast of course. It is nice to know that new engine won't cause any fire like old cars. Also, tranmission problem cause by 50/50 chance. Some abuse or some care. Since, I will care then I'm sure it will be fine. The FWD thing... lol I guess that's life.

I own 3 3100 engines from 1997 Oldmobile Cutless Supreme (sold it 2 months ago ), 2003 Pontiac Grand Prix (summer) and 2001 Pontiac Grand Prix (winter).

History about 3100... I meet that engine first time in April 2001. I like it very much. It was much better than my 1st car Chevy Corisca that I wrecked it. I don't remember what kind engine that car have lol... 3100 engine is pretty good. My old car Oldmobile Cutless Supreme have over 250K mileage when I sold her away to someone. My summer car now have over 100K. My winter beater is almost reach to 60K mileage. When I took my car to service for 100K mileage. This guy told me this engine is very good shape. I told him I changed it every 3,000 miles. This guy told me that's really good. It should last you forever if you keep doing that. It is feel good to know that. It is only one problem with my engine that gasket blown but it cause by coolant. I already send gm coolant lawsuit that everyone complain about that 3 weeks ago. I might get all of my money back but I have to wait and see.

Since my 3100 engine is very good shape. I hate it waste if I throw it away for nothing during swap for new 3800 engine.

I'm going to keep my 3100 engine. Yeah, I can't hear but I will probably get loud booo from grand prix crowd :p

BUT..............

Like AustinGTP.... He blown engine like May or whenever and he use it other chance. I believe his car is 1997. He is pretty good job to keep body clean over 11 years. If something happen to my engine then it will be good chance that I will swap new 3800 engine. My car is 5 years old and over 100K mileage. It will take some time to see what happen in future. Since GM stop making 3800 engine. I think it is safe to say I might not get any new 3800 like 5 years later. Who know how good my 3100 engine. It is still good right now. Sorry long type but want to tell how I feel about 3100 and 3800.

AustinGTP's is a 99. And some of these engines can go for ever and some just bite the dust early, just like any other car.
Guy on clubgp just blew his motor, extensive mods, but found some hair ball like stuff in his oil screen. You're right, you most likely won't find a new 3800, unless you search hard.
You got your car for a DD, that's what it is.
If you now decided you want to Mod like most on here, then you either get a GP with a 3800, or you swap one in!
Yes, they are all FWD, unless you change that, but FWD has managed to pull 8 secs in the 1/4!

New 3800 crate motor.

Palsut, don't do the 3.8 engine until you have problems with your 3.1 engine. It doesn't seem like your fully into the swap so I say stick to the 3.1.

I want to do what rook has done but I'm not going to do that until like a year and a half from now because I'm almost at 200,000 miles and the tranny is slipping a little bit.

I would keep my 3.8 V6 POS as its being called over ANY Ford product on any given day. At least I dont have to worry bout my blocik splitting in 2 like his 5.slo Fagstangs.

I won't swap until it has problem. Maybe I should never change oil so it can blow up? nah

I'm pretty impressed with my new exhaust. I have already drive nearly 200 miles since I fill her up last Saturday night. My gas tank still haven't reach to 3/4 yet which it cannot be right (usually under 3/4 on Wednesday). Now, it is Friday and it is still above 3/4. Huge differance than my driving habit. I like it very much right now. I have read some of you get 21-25 mpg. That's pretty low number. Mine should be 30+ mpg.

I will order my new 3100 cold intake that will help little mpg this winter season.

I didn't swap until I had issues with my 3100... the exact same issues I had before: intake gaskets. They're a plague to the 3100/3400 series engines. Apparently GMs poor decision to use a plastic gasket for the intake, coupled with dexcool, just eats them away. I've lost count of the numerous 60* engines I've seen come into work that are getting intake gaskets done or need it done (yum, cream under the oil cap).

Your engine won't blow due to anything with oil change, it will blow when you get some coolant down in the crankcase and it eats the bearings. It's not exactly a fun job to finish either and will run you around $800 if you have someone else do it. 3800s do get intake leaks, but they usually pool on top of the motor, not in it, and they're much less common.

I got 30mpg with my 3100 on the interstate and 26 or so average driving around my area. My 3800 gets around 27mpg interstate, and 22-23 average, but you have to remember, it's pretty well modded (and that's with me hitting the happy pedal a couple times). I never got a chance to drive it prior to my modifications either.
