Why does no one use the 3.8 V6 out of a camaro?

Oh the FWD people are all over these engines, you can even get the L67 computer to run a turbo motor with some tweaking. Personally I'd just adapt the LC2 ECM onto it because its a MAF system instead of speed density. I'm really tempted to do this as my next project for a road racer.

Maybe you should think about GMs new Global V6....

Low 10's sounds like something to me....

I believe Intense www.intense-racing.com is also the company that builds the bullet proof 4t65e and they have all of the parts needed to make it hold up to some serious power....

The car is extremely fast, but damn, did you look at the mod list? If you have 25K+ for mods , you might be able to build one. I think I would have gone another route.

Don't know any facts about this engine but would it make sense to use it as (with necessary tweaking of course)a replacement motor in a 10-11 sec GN?

Well your looking at forged pistons, $650, custom headers, ~$700, a lot of chip tuning. and a beafed up 4l60E, I honestly have no idea on the bolt pattern on these, as a min. If you are looking for a cheap replacement.... I'd say that this would not be it, if you looking to be original and use more stock parts then I would say its worth a shot. The weak link as I see it is the crank and I've not read enough to know that limits on it is but I would suspect it'll hold up just as well as a tradiational NA crank for the V6 will, meaning treater her nice and she'll survive, probably higher than the old NA cranks do due to the stronger and more rigid bottom end.

Just a thought,

How easy is it to find a good 401 nailhead? or an old Ford flathead? The LC2 won't be around forever and I think the Series II/III will make a economical replacement at some point in the future. When the rarity of 109 parts cause the cost of building a LC2 to be greater than a Series II (for which the aftermarket following can only increase), we may begin to see 3800 powered GN's.

As far as that 10 second GTP, they are only runing 19.8 psi of boost, and I'd bet that block could handle 30+ psi no problem. . . .

 

[TurboBuickSix]

Has anyone investigated if the 8445 heads fit the series II? That would take some trouble out of it.How about an aftermarket head that lets our stuff bolt up and fits the new block? Then it's on to forged cranks (sigh). Until you brought this up I had'nt realized they still used a Buick motor in the F-body.

 

[Drac0nic]

The turbo crank supply will run out for the 109s before anything else does, but Eagle's looking to cover us for that. I'm cynical of the 3800 being a GN replacement block because of shortages, maybe improvements but not shortages. Hell, the 3.8L is/was the #2 engine GM produced, behind the SBC if I remember correctly. There are tons of em in salvage yards, even though they're NA blocks. The 3800 would probably be a good choice because I would imagine they fixed a lot of the oiling flaws in the 3.8. Even if the 3800's crank isn't stress relieved by rolled fillets, the stiffer block should make up for it to an extent.

Here are some 3800 pics I figure I'd throw in.

 

[TurboBuickSix]

Looks like the crank has the rolled radius huh?? Still curious about the heads.Maybe a new aftermarket intake with integral power plate would work.

here's a set of "race ported" heads for a 3800. If you consider that the 3800 SC makes 260 horse on 7.5 PSI boost, you're talking significant better flow stock for stock heads. If you look at the exhaust on those, there's damn near the same exhaust flow as intake flow too.

Hey there fellas,
Im undergoing a turbo project in my 00 camaro v6. I bought a 97 GTP short block with 100K on it for a 100 bones off ebay. I paid $700 for ceramic/moly coated wiseco pistons at 9.0-1CR .020 over. $230 for forged GM series 3 L32 rods, $500 for a stage 2 tranny and $400 for an edge 3000 stall converter.
I also paid $2500 for a turbo kit with a t3/t04e 60trim .82 A/R turbine and .50 compressor. We dont currently have any companies that works for our community like intense or ZZP does for the grand prix folks and alot of the aftermarket parts dont swap between the 2. The bottoms we can swap rods and pistons, but the heads and intakes are different.
We have the ability to tune our cars now with the HPtuners suite, which has been holding us back for some time now. Fuel problems stop us from running much more than 10psi, and after that is really uncharted territory as far as how long the engine will survive.
If you have any question I can help out or point you in the right direction, so feel free to ask away. I have been lurking on this site for a while in search of knowledge, and if I cna give any back I would be glad to.
Also heres some reading for you guys:

nice setup, looks well fabbed. Are you intercooled, or running hot air? With that setup you oughta be able to make near 400 horse at a full atmosphere of boost. Even without race gas it'll be nasty, but with race gas it oughta be a real hard hitter. Besides, oughta be an easy hustle, just tell em you've got a V6 camaro.

 

[snatchSS454]

Sorry for the confusion, but thats not what mine will look like. First I wont have forward swept headers. I have shorty headers and will just use a those. I am only using the ypipe that comes with the kit(pic on webpage)
Second I am using an LS1 procharger twin intercooler setup http://memimage.cardomain.net/member_images/12/web/468000-468999/468763_50_full.jpg
This is them on a car to give you an idea:

pics 20-27 show the intercoolers

Does anyone happen to have GN aftermarket header or manifold setups. I am unclear how your pipes are routed and was thinking maybe I could use some of yours.

Anybody know anything about the bolt patterns on the L36 and L67 blocks? I can't really imagine GM spending enough money to make 2 different blocks for vertualy the same engine so is the 4L60E different from the regular V8 ones or does the pattern off of the 4T60/65e's match the chevy v8 pattern?

Thanks,

 

[Drac0nic]

I was just looking at this yesterday by coincidence. The pattern's a FWD bolt pattern, which means you need to get the trans with it or get one from a 60 degree V6 Camaro and similar. I would think that the internal parts would be similar, but you may wanna talk to a trans person about that to be sure. The FWD pattern is NOT the RWD Chevy or BOP pattern, and I have as of yet to see an adapter for it. If anyone knows of one, I'd be interested in it too.

 

[snatchSS454]

Im not sure if I understand your question fully but what I think your asking is, will a 4l60e from a v6 camaro work on an a FWD L36/L67 application. To my knowledge yes, the L36 FWD/RWD bolt pattern is the same as the L67 FWD app. Now the rwd L36 4l60 tranny found in the v6 camaro will not bolt up to the v8, and the internals are a little different.
Hope thats what you were looking for. Also the 3.8L series 2 is a 90* engine, the 60* was a 3.4L or maybe even 3.1(not sure about those).
Here is some tech data for you

[CTX-SLPR]

That's pretty much what I was asking, I figured the internals would be a bit different but any good tranny shop should be able to make it work. The 60deg V6 your talking about is the 2.8L predominately found in 3rd Gen F-bodies. Thanks for the info on what trannies will fit, I'm always a fan of Grassroots Motorsports Challenge, so this might be a good canidate for a cheap durable powerplant to use in something light.... like a miata.

 

[snatchSS454]

I honestly think the only 90* v6 is the 3.8L series II. Good luck.
Shane

 

[CTX-SLPR]

there also is the 4.3L (3/4 SBC), and the 3.1L and 4.1L's Buicks. The 2.8L and the 3.4L V6's are 60's.

 

[snatchSS454]

good to know.
Thanks
