How many people on this message board have really turbo'd their 2.8's or 3.1's? and how much did that cost? I see many people talking about turbos but no one seems to be doing it, I'm trying to get 300hp out of my v6 but it seems like the only way to go is swapping to a v8 or just buying a v8, its going to be less expensive then trying to make my v6 go fast, what ever happened to turbo Dave? Is he the only guy to have done this? Just trying to figure out if I should just look for a v8 bird instead of trying to make power out of my 3.1. thanks guys.

 

well 300 hp mmm well me and my friends are doing a little expriment with a twin turbo setup 3.1 v6 92 firebird the turbos costed 300 cheap stage 1 each and the intercooler is off a gt3000 we are custom making the piping and headers but remeber you need to do engine work too injectors, heads, pistons cam that if you really want too go overboard but about 1635.55 is how much i spent on it so far alot freebies so i guess 2000

 

Daves12secV6 has done it, FirstFirebird has, a number of other people plan on turboing their engines and I know of a guy here in denver (doesn't visit this board) that cobbled together a turbo setup using a saab turbo and jy parts. He only put ~$250 into it not counting the cost of a previous rebuild. Not quite 300hp, but still fun.

 

Lets see... There was Doward, one of the old V6 Mods, Daves12secV6, FirstFirebird (didnt stay on the car for long). There are many who talk about it but most of them disappear once they find out that there is a lot of work involved. There are others that have put them on 2.8/3.1s in other cars...SixShooter put one in his Jimmy. And a bunch of FWD people have turbo'd their cars. Just not many V6 Third Gens.
I know of 2 that are working on putting turbos on their car-->FirstFirebird and Me. I think that FF is shooting for 500hp and Im shooting for over 300hp...but we both are doing aluminum head swaps( a whole lot better...and a whole lot more work). 300 will be a lot harder when you keep the old iron heads.

 

Never mind turbos, what about supercharging one?

 

Roots superchargers aren't made for our cars anymore but you could possibly adapt some sort of centrifical supercharger.

 

you could just go teh the local junkyard an rip out an entire turbo setup from a sabb and cut an weld it to fit your stuff but honestly with the oil pan drilling tuneing an all that its not worth the time. I have a v6 an love um but if your looking for easy power your best bet is (hate to say it) to sell your car an buy a car with a 350 its easier to build that up to hit 300hp and probabally cheaper in the long run.

 

i'm slowly working on a hybrid/turbo swap. slowly as deals become available. so far in the last month i've picked up a 3.4 for 250 and a 17k mi 3500 for 320. as soon as i find the head for my other engine stand i'll see what the bores look like on the 3.4 and get the appropriate pistons...

 

I am.
So far i have.
3400 complete motor,
a t3/t4 hybrid turbo,
And working on getting a 3.4l

I plan on building the hybrid, and then once thats done.
build and install the turbo system.

 

As mentioned I turbocharged my 3.2L hybrid in my Jimmy. I was one of the first to build a RWD 660 hybrid, AFAIK, the first to build a RWD hybrid AND turbocharge it.

I spent about $2200 CDN at the time, to build the engine AND install it, WITH the turbo system, which included a custom crank trigger and custom headers. Many parts were made by myself and/or my grandfather. I also had new Hypereutectic pistons, new cam (GMPP, equivilant of the Crane 260-2).

I made 218 HP and 270 ft/lbs AT the rear wheels, with too small of an injector and not anywhere near tuned right. I bet there was at least another 40 HP and 30 ft/lbs in the combination with a better injector and properly tuned.

 

I won't be happy if I make less than 250whp N/A with the new engine.

Twin turbos are comming soon.

 

Does anyone have a turbo kit they are willing to sell? I know Turbo dave used to sell some, but I don't know what happened to him, I'm either thinking about rebuilding my engine and turbo, or just swapping it for a 3.8 Buick turbo if I can find one somewhere.

 

Somewhere there are pics of a datsun 510 IIRC that has twin turbos on a chevy MPFI 2.8

http://www.bryanf.com/510/images/510v6e2.jpg

I think the reason alot of people talk turbo is they think they can bolt it on like some just bolt n go part. Its the farthest from it. So they figure that out and dont want to spend the cash, time, or even have the proper knowledge to play in the area.

 

Why not just go with a 3.4 out of a 93-95 F-body and swap in a set of 3600 non VVT heads and put a mild cam in and enjoy 11.5:1 compression and about 300hp N/A but thats also with high flow exhaust, 3600 intake, and a full port match with polish. Lots of power to be made in a 60v6 just not with the 2.8 or 3.1 because there heads suck and flow rate is horrible compared to the aluminum counter parts.

 

does anyone know anything about putting a procharger on a 60* v6 , or any supercharger on a 3.4L v6

 

You mean 3500 heads

 

Yeah I did want to go with a 3.4 but and I still might, but why not a 3.8? Is a 3.4 interchangeable with 3.1 parts? Do they sell 3.8 crate engines with all the parts allready there? Another thing I wanted to ask you guys, I have a neighbor who is selling his 2002 Corvette Engine for $3,000, 30,000 miles, of course I want to buy it but will it fit our bay or am I just wasting my time? Is it too hard to install and am I risking it not working at all?

 

3.8L RWD are hard to come by (older ones that is). GEN II require too much work and same with all the 3.8L FWD

 

uk speedbird im guna supercharge in the end old skool ! im ditching the mpfi going to edel's intake and carb, then when money allows ill get a simple carb supercharger old skool style. its guna whip. ;-)
turbos dont take that much money to setup if you search around, with all the turbo diesels here in the uk theres loads of junkyard parts for nothing. as long as you can fab up some parts your self its just as easy as getting power from a v8 - either way you gunna have to strip the engine apart eh?

from what i can see a v6 car is a good place to start as when they were first sold it wasnt for there performance, so the bodys had less stress on it over the years as opposed to the v8 cars deeling with all that torque for 20 years i think most v6's body/chassis are more solid and cleaner than v8's and beter looked after. anyone agree???????????????

 

Do you mean you are going to put on a roots SC? IF so, good luck. There was only 1 system made for the 2.8....and they no longer make them.
I was going to go SC...until I found out that you can lose up to 50hp(maybe more) just to spin the SC.

 

hi, you could rig any blower up really just make it fit,we'll fab somin up ;-) like the turbo boys are doing, 50 hp to spin it ? really? id be surprized! guess we will see!!

 

I saw a graph somewhere that showed HP loss Vs. PSI...but cant find it now. What I remember might be along the lines of some V8 numbers ...but you still lose some HP to run the SC. Dont get me wrong, Im not tryign to talk you out of it. A supercharged V6 would be bad ***...if its done right you will be able to put down some serious numbers.
There was a member that had one of those kits(Fageol Supercharger), I was talking about, and was selling it a while back.
His user name was Persanity...but he hasn't been on since Sept 2007 and I have no idea if he sold it.
Check out these links, they might give you some ideas.. LINK 1 LINK 2

 

things i can do if i had the right heads, flow jet machine and autocad

 

thanks

 

You'll have to keep me updated on that zs, sounds like you're going to be having fun there if you can get the blower to work! I'm still just trying to get my Bird going! Just finished putting the new LIM gaskets on and fitted a new air pump too. Fingers crossed

 

yeah unfortunatley it may turn into a longterm project as weve just decided to try for a baby, although it will mean ill be parking it up so its the ideal time to rip the motor apart and get it on that stand, should look nice sitting in the lounge LOL

 

If you looking into boost there are a few web sites that you should look at.

This first site has some nice parts for the 2.8L engines, including probe forged pistons.
http://www.fierostore.com/Product/Showcase.aspx


Superchargers made with our engine in mind, though I'm not 100% they still make them.
http://www.fageolsuperchargers.com/

Great sites from people who already make turbo 2.8L engines.
http://www.westcoastfiero.com/headers/2_8_manifold.html

More forged pistons for a 3.4L.

As for the turbo choice if your looking to run on the street and want something nice and reliable a single T3 is a fair choice and you can get them used for not too much, the rebuild of the T3 wasn't hard when I did mine. Next best choice is the one everyone goes nuts over being the T3/T4 hybrids using a T3 exhaust section and T4 compressor meaning more boost then the T3 but not as much as the T4 with a quicker spool than the T4 but the can be pricey. When it comes to V type engines a single turbo isn't always the best solution do to the amount of bends in the piping, sometimes a smaller set of twins is a better solution. With a long run between the engine and the turbos you lose force that can be used to drive the impellers and removing any advantage over friction you may have had by using a single turbo. If you are looking into the twin option I would check around for a set of stock turbos from a Mitsubishi 3000gt VR4, they are common and again easy to rebuild. Hope at least some of this has been helpful.

 

I didn't have time to read the whole thread, but I have turbocharged my brother's 1988 2.8 firebird, and then put a cammed 3.1 in it and turbocharged that. From my experiences, it isn't anywhere near worth the money or effort of turbocharging a stock 2.8/3.1 except for the "uniqueness factor". My advise to anyone else thinking about modifying the 2.8/3.1... I'd convert it to the later style top end-first. Convert the fuel system to aftermarket or at least to a V8 ecm and MAF sensor, then turbo it. It takes a ton of research to get it done, but Firstfirebird and Sixshooter have all the research done and have always been very willing to share information.

 

Do the head swap. You won't regret it.

 

i know a guy on one of my other forums (project89 is his sn over there) who was pushing 11's on a 3.1 running a T3/T4. the car was a monster, he's now going to build a boosted 4.3 for his Camaro

and i know i just revived a dead thread

 

^ Which site, this one, Click Here....?

 

my friend i put nitrous on my car 3.1 with a 125 wet shot never had any problems just nitrous cost alot to refill and with the 125hp hit and the stock 130-110hp to the wheels when ever u need it u got about 230 -240 right there and with some head work and forged pistons u can hit a 200 shot maybe and if u blown the motor drop it pick up a other one and pop it in install the same kit and ur off again

 

LOL, the exageration keeps getting more and more.

And...

No he didn't.

 

Monster, LOL. And that's with iron heads.

 

dam were do these guys come up with this, i love how it goes from looking for to actually pushing, i quess well just have to wait till the 2nd week of march to find out if its gonna be an 11 second slip or 10 second slip

and dam u rob u had to give away that thread

 

I am about order one of those ebay turbos for my 2.8 which one did you get project. I remember reading something saying that the turbos with the blue label have problems.

 

http://cgi.ebay.com/ebaymotors/T3-T4...QQcmdZViewItem

u building headers??? or doing the under k stlye, if ur doing headers i would go with a larger turbo

 

i remember you said on Horsepowerforums.org that you were close to 11's, maybe i've just gone loony in the head

btw project, i'm 1990CamaroRS from HPF. just found the sn was already taken over here (not suprising though)

 

im getting there its just slow going, 12's for now i havenmt really goten to push the car to much this past year. im pretty sure the last times i posted up over there was my 13.00 run when i said i hope to see 11's by the end of the season.

nice to see u made it over here lots of good info on these boards

 

im going to do the under k style headers will take me forever without a pipe bender plus im only doing a very mild turbo install mabe like 7 psi on the 19lb/hr injectors.

 

Umm, are you serious lmao? You do realize that that thread was PM'ed to me from another member here, and I'm pretty sure most people on the V6 boards were already aware of it, being that the thread has over 2000 hits already....

 

lol well atleast not all the cats are out of the bag yet

 

i just bought a turbo from my friend its a garrett m24 cold side said a/r .70 and hot side was like .82 i have no clue what those numbers mean but he practically gave it to me so i couldent refuse. It has like almost no shaft play and its pretty clean.

 

pictures of this turbo???? im willing to bet its a full t4 turbo

 

M24 is a t25 They came on some Mitsu's and a friend of mine had a pair on his Nissan 300zx TT, and those very turbos are in Six_Shooter's hands now.

They are teeny-tiny....

 

Ok I searched the model number and found it on this site
http://www.tunertoys.com/Garrett_T3_...15583-5007.htm

Its a T3 and its damn heavy My friend used it on his civic to hit 440 hp on the dyno. It looks pretty damn big. Ill take some pics later

 

thats a 60-1, thats to much turbo for what ur doing its gonna laggg bad

 

ya thats what I was thinking ahh well i guess i could still use it to figure out where ill mount the turbo under the hood. Idk haha mabe ill give it a try. I can deal with lagg w/e the turbo cost me less than 100$ and i didnt have to pay for shipping

 

That's not an m24 in the link. Got pics of the one you have? Maybe next to a soda can or something?

 

as soon as you start on that project (nixon5) be sure to post up some pics! I am planning on putting a turbo on my 2.8 someday. I'm trying the jy-parts type thing.
