Ok I've decided i'm definately turbocharging whatever V6 I put in this car. (92 RS 3.1L for those that haven't read previous threads). I know I can build a turbo 3.1 using the computer froma syclone or typhoon, however... Since I now have to get a new engine or rebuild anyways I was thinking of going with a 3.4 DOHC provided that it is thin enough to fit between the Camaro's wheel wells. It already has forged internals from the factory, although I don't yet know what the stock compression is on one of these. I figure I can get some pretty nasty hp numbers this way. Has anyone done this sort of swap into a 3rd gen using GM FI, and does anyone know if there is a DIS ECM that is OBD1 that will run a boosted engine. Any input would be greatly appreciated.

Turbocharged 3.4 DOHC Camaro :rockon: (Hey if yer gonna do it, do it right!)

Thnx
Brian

 

As long as its a 60 degree block I think you should be ok. If its a 90 degree then might as well put in a V8

 

i know itll fit. there's a guy doing it right now in an 86 - not turbo tho. problem im running into is no ecm thatll control a dohc with boost. im gonna say you possibly can use a w-body ECM and a richened up TGP(turbo grand prix) code.

what trans are you gonna use? i dunno if the 700r4 will have the clearance on the bellhousing for the drivers side starter.

you should check out the DOHC sections in the 60* v6 part of gmforums.com, couple guys workin on turboing them(including me, but theyre over my heads with the computer stuff so im just gonna copy them when done)

next you will be messing with custom accessory and belt. also, they dont have forged guts from the factory.

depending on the year of DOHC you get, compression will be 9.25 or 9.5:1

i have a T3 for when/if someone figures out a computer code to work with the 3.4. my problem is the electronic trans...

right now, im workin on a twin turbo 3.1 with FWD aluminum heads and intake, 2 t25's, 2 intercoolers, and a T5 trans(ka-boom!). gonna use a turbo grand prix ECM and chip, DIS, and a 3.1 harness outta FWD 5 speed w-body. the T5 bellhousing has provision for the drivers side starter that the front wheel drives use.

oh ya - keep in mind, on the DOHC, its a FWD block casting, so your motor mount bosses are not in the same positions either.

i love 3.4's

 

Dont listen to that troll SVT, you should define the input cause you get fk nards like him spewing his v8 bull****,


go someone else SVT your opnion is not welcome on the v6 board.

 

I was always told a DOHC 3.4l might not fit. And if so, the starter is on the wrong side. however, anything can be done with $$$

 

I was planning on using the stock 700R4 tranny. I got my information on the DOHC engines from here: http://www.angelfire.com/ca2/34Performance/dohc.html
It says in there that they had forged internals. Either way I'd have to put new pistons in it to lower the CR to 8.5:1 max. However no one has been able to tell me if it will fit in an fbody or not. I do'nt have a problem with moving motor mounts and such. I guess I'll have to do more research on it. SVT even if the 3.4 was a 90* I'd still stick with the V6, I already have another camaro with a 350. I want to build a V6 that eat up a mustang cobra for a mid-day snack j/k. The point is to advertise that its a v6 (which it really will be) and then make them cry when they're picking Goodyear out of ther grille.

Patgizz, I wonder if you can get the compression down low enough using FWD heads, those are the fastburn heads but they have very small combustino chamers and although with a supercharger valve shrounding isn't as big of a deal as NA motors, the CR on that engine may be too high to run any kind of boost over 4-6lbs on pump gas even with intercooling it. And your right about that T5 trans, kaboom is an understatement, although at the compression it sounds like your gonna be running with those heads I think your engine and trans will be saying Kaboom in unison.

Anyways, thanks for the input guys, I really appreciate it. If you hear of anything else that may be helpful please either post it or e-mail me at brian@netrodyne.com .

Thanks again,
Brian

 

i'm not sure if that will work. i used to own a grand prix, and those 3.4 dohc's are pretty fat engines. the 3.8 series 2 is more compact then them!

i doubt you will clear the strut towers

 

Thats what I was thinking. Does anyone have the dimensions of one of those engines with the heads on it? I think the motor might fit but exhaust manifolds/headers might be a different story. Well I could always put zoomies on it and cut holes in the fenders for them j/k.

 

im definitely rebuilding the bottom end w/ lower compression(its at 8.9 n/a now) pistons on my 3.1 so i could run more boost.....

ill measure the DOHC in my lumina later today at some critical points for you. ever since i yanked the 3.1 out in june and put in the 3.4, i've been having a blast and would never go back to a n/a 3.1 ever again

 

ok i went out in the rain.

all measurements were from widest point to widest point

DOHC:
valve cover to valve cover: 24"
exh manifold to exh manifold: 28"
bellhousing to timing cover: 22"
bellhousing to front of pulleys: 24"

2.8 v6:
valve covers: 15"
exhaust manifolds: 22"
bellhuosing to timing cover: 17"
bellhousing to pulleys: 21"

small block:
valve covers: 21"

472 cadillac that i had in my 85 iroc w/ modified BBC headers:
valve covers: 25" - only measurement i have cause it is on the stand now. it did fit and was tight, but no more so than a big block chevy


so go measure your strut towers and see what happens. you wont be using the FWD manifolds anyway, youll have to fab some custom headers or something.

 

If you're going to do it, then please, do it. Nobody's done anything about turbocharging yet, but they sure can talk about it!

 

Thanks Pat, I think it'll fit. If a small block is 21" then the DOHC is only 3" larger, but I'm sure a BBC is larger than the DOHC by 1-2" and plenty of people have stuffed on in 3rd gens.

Tom, I agree with you on that note. I'm workin' on it.

Check this out guys: http://www.fiero.nl/forum/Forum2/HTML/027692.html

The fiero guys are a great source of V6 info.
I think if someone can squeeze a DOHC in a fiero with a turbo I can squeeze one into an fbody. After all you can do anything with a plasma cutter and a 12lb sledge.

Thanks again

 

Holy crap that website's slow; and I'm on a fiber optic line. I'll try it again later. Where is .NL? Netherlands?

 

.nl is more like new zeland....but looks mean...

i wish someone put that thing in a camaro...

 

Listen junior I'm anything but a troll. I was at this website before it was even here. How many of you here remember the OLD website? Prolly about 5. And a V8 is bull ****? Riiiight, after you ride in one you tell me they're bull ****. I was simply saying if its not a 60 degree block the install would be like putting in a 90 degree block V8. But I'm sure your *** didn't make it far and have no idea what I'm talking about with the degrees. Sit down little boy before you get burnt.

 

A few questions about a 3.4 DOHC swap.
Will it bolt up to the 700R4?
When swapping in its computer how is that going to interfer with your thirdgen instrument panel?
Whats the fuel economy on one of them?

 

well,

it will bolt up to the 700r4 or t5. all the 60* motors have the same bellhousing.

i cant speak for anyone else, but in my lumina when i went from the 3.1 with a 3.33 final drive to the 3.4 with 75 more HP and 1500 more usable RPM, and a 3.43 final drive, i went from avg 19/27 to 18/24 BUT the highway #'s are skewed cause i dont have my converter lockup wired in yet. id say probably lose 1mpg overall compared to the 140hp 3.1 and probably the same to the 2.8

theres 2 DOHC motors, complete w/ harness, in the junkyard here for $400 a peice - they dont know why they dont run but the timing belts are intact. if you were looking for a good complete rebuildable motor since you'll be into it anyway to do the pistons.

 

I agree. A lot of people who talked about it only got as far as scavaging a turbo from a junkyard. I would really like to see a turbo or supercharged 60 degree V6 in a thirdgen. I prefer supercharging because it requires much less computer programing.


What it really comes down to is $$$$. It's going to cost at bare minimum 2k for a working setup. I just wish one person would do it successfully.

 

snake you sond like a punk!!!

from what my bro told me you f*cking lie and you only 18

awwwwww you momy pays for everything you have

if you got so much sh*t to talk meet me somewhere and well see who wins

and bring the supercharged rustang

if you dont have a f-body or if you dont whant on get the f*ck off

 

Walmart on Wudruff road. This sunday@8:00p.m, I'll be out there along with some other rustangs you can try out. Oh and who is your brother?

 

Ok I have to know the outcome of this one. Someone post it after sunday... BTW is it me or did it become a little bit too hostile in here? I'm like the king of GM and Ford rivalry, but I think we should limit it to joking. Just my $0.02 worth.

In the words of... someone "Can't we all just get along?!?!"


Later
Brian

BTW Pat, I'll be taking measurements on the car this weekend, I live in Jupiter and the car lives in Vero Beach (until it has something under the hood to motivate it anyways). Thanks again

 

Oh it will be on video for you to see! And yes this has become too hostile in here. I know the V6 board is a bunch of people that get sick of hearing "swap in a V8" but I haven't said that once. I did however say if you are going to swap in a engine that isn't a 60 degree block that you might as well be swapping in a V8 (too much trouble). But I get flamed for it. Oh well this guy bucked up to me, insulted me personally, and he lives in my town. Lets see if he shows up...

 

I can get the headers made for anyone interested. Email me and we'll put it together.

And to Gumby.... I know its easy to get offended by us V8 guys cause we tend to start a lot of **** (kinda like big bro picking on little bro) but I think SVT didn't mean to start a flame. I think its really great all the effort you V6 guys put into your cars, but just try accept the fact that most V8 guys are closed-minded and can't accept V-6's as performers.

 

im makin my own headers for mine, but 87 would need some if he isnt up to it. the DOHC has a different flange and port loc. than the regular 60* motors.

 

How much $? :hail:

 

Off the top of my head I would say stainless (mandatory with turbo) would cost between $600-$800. If you are serious and want an accurate estimate email me.

 

im working late sunday! but maby saterday?

 

and i wont get my brother involved in this its between me and you!

 

Sure, when and where? I might show up if I have nothing better to do.

 

Alright, don't get yourselves killed on the street; take it to the racetrack....

 

wall mart 8:00 ill be in a 90 rs camaro red!

 

I might meet you there. I'm going out somewhere else and meeting up with a few mustang friends. Its a big street race but I really don't want to say when and where on here if you get my drift. I might just head out there tonight to see a nice third gen. Which Walmart?

 

Dude..yes Snake doesn't have a F body and can be a bit of a PITA..his Mom probably does pay for all his toys too..(if they really exsist that is??)...but you swearing up a storm doesn't make you look any better. Calm down and please... watch the language.

 

As for you Snake ( Monkey boy) You talk all this talk, yet seem to your way out of racing people...go race. Win or lose doesn't really matter. You've got a big mouth, now it is time to fill that mouth with, either glory or Crap. Don't play games...go race him and shut up! I've heard so much crap about this stang of yours...lets see if it is for real!

 

Please let us know how you make out. Win or lose. Please win! I'm sick of this Monkeys crap...it is time for him to eat his crap like his brother and sister do.

Yes Snake! I'm sure you realize I don't like you to much. You, yourself have led me to this conclusion. You dug your own holes in life. Question is did you dig so far, that you can't get back out????

 

BS my way out of racing someone? I said I would race tomorrow night and he wants to race today. (giving me a days notice) I have been working non stop today trying to get my car up and running so I could go race him so how bout you STFU until you know what you're talking about. We will see what happens

 

Yeah OK! I'm done with the likes of you...Grow up PUNK! I know exactly what I am talking about. I have read many of your so called posts here. Almost all and stirring of the crap. Why are you here??? No one likes you...don't you get the picture? Your a big mouth little jerk. Go away! Please! Save me the pain in my eyes every time a read one of your posts. One last thing..why do they call you Monkey??? To much crap in, or coming out of your mouth. Is that your face or are you talking out of you AZZ again. Sorry Moderators...this kid justs ticks me, and alot of other here, off. I will stop....

 

LOL calm down. I got an easy solution for you if you don't like me so much. Just dont read what I say. You see a red SVT under a name be like "oh crap thats snake" then just skip by what I have to say then read the next. And you called me a PUNK. *gasp* thats a bad word! :sillylol: Get over it. Also I have no idea what walmart we are meeting at!?!?! I guess I'm just going out to walmart on wudruff


Edit: I want to know what I post. So give me an example.

 

Aww hell this isn't fair. Xceleratecamaro isn't even gonna race me in his car. He is racing me in someone else's 383 Carbed RS. WTF is that, gonna try to beat me with a car that isn't even yours? So sad

 

Hey Snake..just did a search on your nick name...Funny thing was about almost half of the threads you made a post on got closed! All having something to do with you! This one will be another on your list. I don't really care what kind of car you have or how fast it is. Personnaly I don't think you should even be racing anywhere but the track. Don't underestimate Snake....Why is you car not running?? I just read some threads with you supposably racing someone a few weeks ago. Who care I'm finished with all this. If you plan on staying here fine...just be more carefull how you present yourself. And then everyone can get along.

 

None of your business why its not running. Its broken, you know them Fords! Anyways the reason my post got locked is because of people like you and all that start **** with me for no reason what so ever.

 

why do you morons have to go and ruin a good in-depth technical post with this bs

 

I certainly hope you aren't talking to me??? The last thing we need is another person calling people names. I stopped this conversation on my last post, and hoped it would be closed or fixed by now... I am here for the better of the board. It was kinda wrong what I did, and I admitt that, but this kid is full of it. I will not explain myself any further.

87SC/SS I appologize for this in your thread..It is all yours. I'm done! Again...87SC/SS..sorry.

 

not you, the other 2 geniuses. hopefully it will get edited and not locked up

 

Well I hope it doesn't get closed really cause 87SC/SS may not get all his questions answered, and then I would feel bad. They probably won't edit the posts either. Well it is up to the Moderators now, and I will respect what they choose to do.

 

how about we forget all the bs that was talked and turn our attention to the real topic at hand. as far as a turbov6, how about the 3.8 man? think about they got 200hp stock, plus if you add the turbo you got around 300hp, that would be pretty impressive, also you can easily find a 3.8 out of a junked 4th gen for pretty cheap
just my .2 cents though, if you can find a engine out of a tta then you are golden

 

being as the bolt bosses are different between blocks for FWD RWD id suggest pirating a 3.1 GTP turbo motor for everything but the block. this menas ECM wiring etc. i would then transplant all these parts into a RWD 3.1 block. including the crank sensor and the dIS. use the GTP turbo etc. this should net you with a doable parts combo. aside from tying in a few wires it should be really simple to do.
