It just doesn't make sense to me from what I see at the shop that the 3800 are built that strong. It seems like something happened around 96 or so that these engines went down hill.

I dont know if it's just becuase they are so popular or if it's the fact that at one time or another they have all overheated and warped the plastic intake to the point of filling the crancase with coolant.
But I have never in my career seen an engine come in so often with bottom end problems.
i have seen a lot of the 3800 with the plastic intakes warp/crack/blown gaskets who the hell knows i know they go bad alot. i had a Bonneville with a 3.8 never over heated and the damn thing leaked and hydro locked the motor.

i think its cool when people build up v6s. there was a guy that used to go to a local car shows with a low 13 second turbo 3.8 was cool little car. i dont know the specifics on the car interms of what turbo setup or if he had or hadnt rebuilt the bottom end. i havent seen him in a while and i dont remember and i dont want to post false facts

I'm probably not being very subjective about this. I think I just got a bug up my ass about the newer 3800's.
I used to love the old 3.8's when they first went sequential.
They seemed like awsome motors!

the SC3800 is built well and has heads that flow like stage heads. A stock turbo and long block GN has been 11.37. No reason to doubt a turbo3800 won't be slow.
This car has way more than what you mentioned and the car that is closer to what you mentioned pulled a 12.63. That's not low 12s to me :p

I am also not saying a 3800 can't be fast, cause they can be ungodly fast! Hell, I saw a Firebird pull an 11.3. It didn't sound anything like a V8 so I found him and talked to him. The car was an N/A 3800 Firebird. His car was sick.

THe car that laid a 12.63 could have been running low boost, I guess it was a bad example on my part. THe other car ran faster than a 12 with just rocker arms and exhaust, which I would assume anyone putting a turbo on would have exhaust done anyway.

I've never ever seen or heard of a n/a 3800 going that fast! Did you get any details on the build? I could only guess he was spraying, right?

The dude that ran 11.8 also had a nice wheel and tire set, gotta remember that. As for boost I'm pretty sure you can't run anything too high in the 3800s without doing some major work or a high risk of blowing it up. I know for around $1,000 I could get my GTP running in the 13s with the smaller pulley and exhaust work, but even doing that you risk issues. After that the motor work gets pricey very quickly.

The dude with the N/A 3800 was way over my head but no, he didn't even have spray. The car was also fully gutted running slicks and skinnies. I know the motor had a lot of work done to it with a lot of scientific and mathematical mumbo jumbo. It was his third 3800 motor I believe because some of the experiments ended badly. He was the mechanic and he had a friend drive the car. They are fairly serious racers.

Another person I know has a GT and did a top swap, cam and some other big changes. He also ran slicks at the track and trailered the thing there and back. He kept boasting about how he was gonna run a mid to high 12 and totally kick my ass. One day we went to the track at the same time. He ran twice with a 14 and a high 13 and then the car broke down on him. He then proceeded to throw a fit like a complete baby. I met him a week or so later and you should have heard the excuses.

What I don't get is why someone would waste so much time, money, and effort into a n/a v6. Why not turbo it and be done with it? I've been thinking about getting a supercharged car for the wife after I get the truck paid off and getting one of those turbo kits since I can use some of the leftovers from my turbo t. My question is, how long will the transmission hold up to these bigger turbos and 25+lbs of boost? I find it hard to believe that the pt61 wouldn't kill a stock trans at high boost and at the same time does not need a converter. THose are 10 second capable turbos in the GN world.

The gentlemen that does my tuning (Bruce at Aggressive Automotive Performance) won the TSE class a few years ago. He is a master mind and even pumped out over 40 hps just on the tune alone of my car. He has put many LT1 cars in the single digit numbers.

I went to his annual yearly event last year and a customer Grand National he built ran an 8.89. The customer himself doesn't even use the car at the strip, but instead is a serious street racer that bets on 1k+ races. Bruce told me that the car I saw wasn't even the fastest one he's ever built.

As for the N/A 3800, why not? It obviously impressed you. Also I don't think the guy spent any big money on the car. If I remember right he has his own machine shop and ground the components himself. I would rather have his car than any of the ZZP cars I've seen at the track. The last SS Cobalt ZZP car I saw was going under some major issues.

I did see a guy with a turbo grand prix run 11.7s all day long on a motor that had 240k miles on it. But his car had A LOT of work done to it.

I can't believe I made that mistake a long time ago.
Bought a v6.....got attached to it and just kept trying to make it fast.
I realized a simple forged rebuild would cost me out the ass.....THEN I still had to drop another $5000k on the procharger....then I had to get it all tuned and troubleshoot it.......realistically.
Then I had to swap the Rear, Trans, Brakes, driveshaft, pay for tires......
I just realized it wasn't worth getting into debt JUST to prove a v6 can hang with v8's.......plus likely blow my motor and have all the high maintenance that comes with owning a supercharger...


Second time around I just went straight for the v8, and it only cost me $3k.
And it's cheaper/faster for the money.:lol:

Yea, no doubt... That's why I'm keeping our GTP stock... I might do exhaust, tune and suspension down the road just for shits and giggles. I need to get my fiancee a new car after we get married though before I do that.

I would love to get my old v6 m112 car back. The power was insane for a v6. I could run a 12 easy. and still hang with the shelbys. What i like is the satisfaction you get because mostly gt owners are cocky as hell when they see a v6.

There's a nice newer V6 stang around me, the guy works at the corner store. It sounds really awesome as I think he said he has full exhaust. Also he put in some 3.73s. I have a feeling he surprises a few GT guys.

75 wet shot nitrous kit. (450 bucks). Once youve had your fun with the juice, and have blown up that motor, go buy a v8 k-member and an Lt1...Then put the nitrous back on it.hehe.

The last time I got next to a mustang GT on the road I jumped on it at a 35mph roll and smoked the tires sideways next to him. I guess my little buick v6 with the stock turbo was a bit too much...on 22psi:devil::thumbsup:
