Q for you Turbo Guys

[fast_ga]

Allright, plain and simple question here guys. Has anyone on here sucessfully Turbo charged a 3400? I mean got the bugs worked out and have had good results and have a turbo 3400 that runs good and can be driven daily? Ive seen a lot of projects here lately with turbos and i've seen most of you having a lot of problems and a lot of bugs and a lot of things not working right and i really havent followed the threads to closely to know what ends up happening. Just considering my options here, wouldnt mind starting a turbo project but i dont want to dump tons of $$$ into something i wont be able to properly tune and get running right ya know! Some input would be greatly appreciated.

Theres been some that fabricated their own, but the only turbo in the market for us, its already up and running is the HP Turbo. Website is www.turbochargedpower.com. Talk to phantom505 his car was the one doing all the testing on. He knows quite a bit.

to be honest. If you want big power buy a car with a turbo stock that can handle the power. It will be cheaper and less trouble free. Not to mention you can make lots of horsepower reliable

[FORTEEN3GT]

Just to let you know... the 3400 V6 is a great motor for turbo and boost!!! it is very reliable and has a really strong bottom end....

compression is only 9.5:1 ...so it will take 6-9 psi really well..

without 8:1 compression you shouldnt boost 12-15 psi..... but who needs 12 psi......

6-9 is enough for a 300 horsepower car!!!

anyone that says otherwise doesnt know GM!

The tranny with 12 psi is the only issue....at 6-7 psi it holds up well.....kind of like a 75 shot of nitrous.... 12 psi is like a 150+ shot which is not good for the tranny!! as a comparison .....hope this helps!!

Doug i know what you mean there man, this is all just a pipe dream really. I was just thinking about what i wanna do to the car if i get bored with it! Im sure i wont. If im gonna have a turbo i got to have a 5 spd thats just how i feel. And so far no one has been able to get a 5 spd in a V-6 GA..... except for GM themselves! So yeah i will eventually get into a car more suitable for big power upgrades.

This is the perfect car for doing things like turbos. I'm so sick of "it wasn't on your car when you bought it so it shouldn't be there now."

Just look at the power ... and I've barely begun.

The HPP kit is fully tuned with a DHP computer, BTW.

Dude relax, im not saying that. What you are doing is awesome and i commend you! Id love to do what you are doing! Just a little out of my range of funds at the moment. Plus i dont have the time to make trips allover the place for tuning and this and that. Trust me i know the 3400 motor can take some nice boost and hold up to it, i know what these things are made of i work on them all day! I just read that huge 20 post thread on your ride and the turbo kit, lots of good info, and im glad some companys are starting to get into the Grand Am performance aftermarket! Good luck with everything man.

Yes and while your making 300 hp I'll be making 500 rwhp reliable.

[phantom505]

And you'll be running the same times. Supras are dyno queens, that's a well known fact. I went to the some MarkIV page and they had 500 wHP Supra's in the 11's. At 300 wHP I know I'll be in the 12's, and I'm willing to bet at 350-375 range I'll be in 11's so long as my suspenstion holds up.

Case and point: http://www.mkiv.com/main/index.html

[Doug]

mkIIIs are not dyno queens We can actually hook and run good times

[FORTEEN3GT]

dyno queens???

1000 hp supra's run 10's!

1000 hp mustangs run 8's!
1000 hp trans am's run 8's
1000 hp grand nationals run low low 8's!!!

you are right....supra's have problems with putting power to the ground....they are not setup for drag racing! it has been proven.
but they do look sweeeeeet! my fav car! only way for them to run 8's is tubbed out with a ford rearend...and a 3 ft long rear axle!

There are a lot of people working on turbo kits. Some will spend thousands and still be running 14's- which is pathetic.

So far, if it came to "Put Up or Shut Up" all the turbo grand am's would have to shut up because none have run any better than 14's. Sorry, but this is a fact. I hope that we will see something interesting from these people by the end of summer......we'll see.

[SpyhunteR]

It doesn't take a 1000hp supra to run 8's...

a local supra here in vegas runs 8.8-8.9 last track event, and he has under 1000hp... dammit..

Finally!!! Someone who isnt
Anyhow im just researching different forms of boost and i've seen in person some of the supercharged guys run, just havent seen a turbo 3400 run yet, just heard a lot about projects getting started and going bad so that was the reason for this post. Right now it looks like continuing my NA mods are in my best interest cause i can do most of it myself since i have the know how and the tools and its the least costly. But i am interested in boosting my ride eventually.

Well from what I know.,.....have read i should say.....if you want expandability with your boost, stay away from S/Cs. Turbos are really the only thing you can up without having to get new pullies or another blower.

Im not an expert, and I will run N/A unless I get a good amount of cash someday right up front.

Anyways, at the moment I dont see anyone doing better than 14's on the track. I am not sure what all you guys have done to your internals (forged pistons, new cams, new crank, bigger oil pan and better oil pump, bigger fuel rails, new ecu, P&P everything, and whatever else (exhaust, lightened car (real light rims/tires), lowered, etc)). Seriously though, to get REAL numbers...less than 14, you need to spend cash. HP/TQ and low numbers cost a lot of $$$. There is NO WAY around that.

[Doug]

ditto. I put 6 grand into my turbo grand am to run 14s. I just put an intake/3 in exhaust on my supra and it will proabaly go mid 13s now. Best 600 bucks I've ever spent. Having a car with tons of potential rocks.

[phantom505]

Is this a Supra site? Geez by this post it's hard to tell.

Go elsewhere if you want to talk Supras. It's not hard to modify a car that comes with boost already installed. It's that simple. It comes from the factory practically tuned. So other have to work harder to make it work as well. So what? Isn't that part of the fun?

I'm not building this car to run 13's. If I wanted to do that I could have, and probably killed the transmission. I'm building to run 12's for now and will be much faster than that in the future.

Right now I'm running 9 psi and very few stock cars on the road can even keep up. Actually, I have yet to run into a person with enough balls to try to take me on the highway. '97 Cobra gets me on take off, but then again it falls behind once the wheels start rolling. It would help if I dumped the stock tires.

It's a fine daily driver. It's a little harsh when you step on it, but then again most cars of any respectable speed are.

[Doug]

Just trying to warn people who don't want to waste a lot of money on there grand am for crappy results. I have seen it time an time again.

[phantom505]

I don't think it's the GA, I think it's the people building them up.

I have a fast supra. In response (Never seen one of those before .)
I have a fast Grand Am. In Response (Now that's something I've never seen before...good job.)

See what I'm getting at. It's nice to have a fast car and all, but it would be more fun in a GA. I'm not trying to put down supras. Hell they're nice cars. I would just rather build up a GA.
