I need to know if someone knows if i can put in a Garret Air research T-12 with intercooler, 4 wire oxygen sensor and housing, wastegate, and tubing for the intercooler.
it was pulled out from a saab 16 valve 2.0L.
i wanted to know if the turbo was big enough to do a lot of power and if it is can it fit.... because i can get all this and go buy a really good blow of valve like really soon
i'm going to buy the 3.4L tommorow.
if anyone can help me
also i need advice from people like Ked to know what i should put onto the 3.4L for power upgrade
i'm going to hunt v8s and i need knowledge and power

89 Firebird 2.8L with Y pipe, flowmaster, K&N, rebuilt tranny.
soon going for 3.4L
need to know what cams and/or valve covers, valve springs, rocker arms, and intake.... i really need advice on intake, mine is destroyed. so i gotta make one or something for my incoming 3.4

Al I can suggest is that you will be blazing new territory.
Be the first and educate us.
I doubt the turbo is large enough.
You need a turbo for a 6 cylinder.
Even Nissan used two turbos on their V-6 Z Turbo'd car.
Not saying ya can't just, enjoy and keep us informed.
Add ons?
I like good running tranny myself!
Beyond that, the engine is quite fine, as it.
I'd go to Extrude Hone and have the heads, upper, middle & lower intake cleaned out.
While at it, use the stock manifolds, get them extrude honed, also.
Incidentially, for real power, Ihave V-8''s
I love this V-6 as is.
Quick, fast, powerful, economical

KED85

Oh
Make sure you spend the measly $6 for the GM Performance Parts book.
Any GM dealer.
Worth it for every answer you truly need.

goodluck, take it to a speedshop and see what they think.

Project: 85 2.8 bird

planning on putting a turbo on the 6?, sounds familiar.

My turbo has a built in wastegate , it was from a 4 banger mustang motor.

don't forget the oil lines, put a cooler in before it gets to the turbo.

Watch how much psi you run, the 60* motors have a relativley high CR

Camro_Hunter_D will "eventually" have turbo headers, but I was planning on just running off the exhaust manifolds

I'm still looking into this, but I was thinking of pilfering an ecm & injectors from turbo GP.

Up the fuel pressure.

Why would you need a 4 wire o2 sensor?

most likely an FMU (Fuel Management Unit)

Some people like turbotimers, others will just sit in the car & let it idle for the 30 secs & then shut off.

Get the 3" cat back system, will flow better w/turbo.

damn, all these people getting motors but me , at least my suspension will be new.

Project: 85 2.8 bird

The stock 3.4 cam is good, get new springs installed though when the tubo is installed, & spend the $$$$ to get the crane full roller rocker arms.
Edelbrock & other 2.8/3.1 chrome valve valve covers will fit.

make sure your tranny is up to snuff, also

First, my only question is are you on a tight budget? If you are, maybe this project isnt for you. We're working on running garrett t3's for our olds 455 boat, and the money factor is large. if i were you, and it were me personally building the engine, id run a full forged rotating assembly. Get Ross Pistons, get a GMPP 3.4 forged crank, some manley connecting rods, and SS pushrods and valves. Have the 3.4 heads ported and polished. Have the combustion chambers opened up a little. Make sure to use high tensil strength bolts through the whole engine. Dont want to build a high $$ motor and have the thing blow up on you because you put in cheap hardware. I always recommend ARP bolts. See what you can do as far as a fuel system. Adjustable fuel pressure regulator is a MUST. Possibly a second fuel pump. Also, that turbo your looking at, its too SMALL! If you can find another one, run 2 of them. my 2 cents.

Project: 85 2.8 bird

good catch Graeme, AFPR. my bad. you got a boat too?

any opinion on my turbo? the f*rd motors were 2.4l

Graeme'sFirebird

Yep! got a boat, 22 1/2 foot Konda Day Cruiser

Project: 85 2.8 bird

mine's a 18.9" 76 pontiac bonneville w/a 400 inboard

Keoki_Firebird89

Okay its the day i went to handle the whole 3.4L thing
monday i'm getting the engine
apparently my dad (I'm 19) went crazy and is taking the engine to port and polish. now...... the polish guy tells me i need more lift so i take full potential of the everything hes gonna do to my engine.
so i'm here thinking....more money.... ::scratches turbo plans for a few months:: BUT HEY I CAN WAIT!
guys i'm gonna attempt what many attempted before.... making the v6 a v8 hunter
of course i'm sure many have said that and failed or gave up.... so i need help from all of you to remain focused.
does anyone know a camshaft kit with more lift than what the 3.4L has to offer, which by the way i know are good cams.
i'm also looking for the roller rockers
some people say compu cams some say crane cams.... i need to know which one is better and should i go 1.52 or 1.62.
the turbo i found is for 500 bucks and it brings the t-12 and all that other stuff i listed minus the blow off valve which i already found which one i want.
I have a Y pipe, flowmaster, no catalytic converter. In miami we have no smog regulations, K&N. I have till monday to handle all the parts i want to get for the engine. all these parts aren't gonna cost me the labor... only the price of the box. Yes i am running in a tight budget, but don't mind that. The budget is cause its all i have saved up now. I will have a lot more money... so i might be able to pull this off.
Also what accel wires work for the 3.4
and what spark plugs should i get considering platinums aren't good for boost(turbocharger, supercharger) and MSD.
So basically for sure on monday i'm getting the engine, its gonna be ported and polished, as well as a few minor tinker ups.
what do i do about intake.
okay all my questions must be annoying you guys... sorry about that
thanks for all the help so far.

follow this link: Tiago
he modded the sh*t out his 3.4. gives you something to think about. Best to do as much as you can with the 3.4 out of the car so you can still drive your car around & get parts & stuff.

the most recomended plug I've heard of using is NKG.

You can get more info inthe ower adder forum here or @ firebirdv6.com , they're a v6 forum.

KED85

Extrude Hone would probably do your work for about $600+.
Just reassemble the heads with fine tooth comb,.

AlexJH

If you're going to turbo, you might want to think about getting a Sunbird turbo/GN/Syclone/Typhoon ECM to take full advantage of your forced induction.

Have a look at craiger's post on the DIY PROM board.

Just a small point, Keoki....it's a federal violation to remove any of the smog equipment. I live in Jacksonville, FL, where we dropped our smog inspections last year, so I don't have to deal with that state stuff either.

But, you're planning to build a ride that's going to draw a lot of attention. Although rare, the feds can actually impound your car for failure to comply...and it doesn't take a rocket scientist to determine whether or not you have a cat installed.

Why not look at one of the low-restriction ones like Random Tech?

Keoki_Firebird89

Well about the cat. It broke and i only had so much money so it was cheaper and more power came out of it as well as mileage
i'll look into that cat you told me about.
yea i'm getting all the engine components i can afford now while the engine is meaning i only pay for the price of the part.
i'm gonna try the edelbrock performer plus cams for the 3.4
and i'm prolly gonna order the valve springs to match with it
also i need to know whats the difference between non rotator valve springs
and rotator valve springs, but i think the rotators are the ones i have to get
i'm looking into the crane cams gold series 1.62 roller rockers
and i think i remember reading fiero valve covers are a good uprgrade for the 3.4L can someone confirm this cuz then i can get this cheap.
now count the port and polish.
and everything i have already... i'm gonna have a decent car
what do you guys think i'll do 1/4 time
the mod list is:
3.4L engine
2.8L intake with the box open
k&n filter
Y pipe
Flowmaster
no cat
crane cams 1.62 rocker arms
edelbrock cams
edelbrock valve springs
port and polish
and the fiero valve covers if its true that it is an upgrade

Also thanks guys ... your a pretty cool bunch
i asked a question and you all helped
keep up the good work!


I'll keep informing you... who knows .. i might be the fast 3.4L guy around here.... of course with the help of all of your knowledge.

i plan on working on the ignition system when i recover from the whole 3.4L swap.... finacially recover that is lol

i'll work on the ignition system and air intake system...

then i save up for the turbo
i'm prolly gonna get the first choice turbo i wanted to get since i concieved the idea
Garret T3/T04E Turbo with built in wastegate

I might get a new job soon and that means i can definitely afford the turbo project.
Then i explain everything to you guys and who knows
we might start a V6 revolution
lol.... or not...
i just wanna be fast.

I cant find a website for this place but, "RAYJAY Turbo" makes some turbo kits for all kinds of apps they might just have one for a v6, but like I said I cant find squat on them.

Graeme, A mustang?? What happend to the Chevell?

Camaro_hunter_d

Actually the turbo's that nissan used were really too big, thats why they had that really bad take capability(LAG). Compare there turbo's to Porshe for instance(I know its apples to oragnes) But the reasearch that porsche put into their system shows in the results in performance. Nissan built a general performance that takes a while to get going, while the porshe system is effective nearly off of idle.

When designing a turbo system, the biggest critical thing to do is get the turbo size that you need, not what you want. Youwant a low to mid end, you have to use a smaller turbo. It will kick in off idle, and let you rip the low end, but after 3500 RPM's it has nothing left to give. You go bigger and you get the mid to high. meaning you have to be going over 40 MPH before you really get anything from the turbo. Not a stop light runner. Now what nissan SHOULD have done is go with 2 smaller turbos that being they are smaller will improve the low end, and being 2 thay can hold the PSI into the higher RPM's through sheer amount of flow.

Camaro_hunter_d

Ok Honestly what I was thinking of the turbo system for our cars was this.

a SINGLE T3/4 Hybrid.
This would offer good kick in at about 2K through 3800. So still not a good high low end booster, if you have the manual your in heaven cause you can hold it there before take off, Auto's you need a higher stall 'verter to do it.

Oiling system, nothing fancey or extravegent. Oil tap at the pressure sending unit that would go to an oil cooler, THEN to the turbo.

ECM, all custom PROM. I will make the program in my 92 speed density 3.1. 2.8 guys sorry thats what your stuck with. I will recomend to anyone that gets this system to go to a junk yard and switch from MAF to Speed density.

Engine internals. To be worked out. I need to get the ratio down to about 7.5-8.0 to 1. NO HIGHER, for any amount of decent boost. I personally plan on getting the system to about 15-17 PSI for my car.

Exhaust system and routing to be made my me. All custom. I DO PLAN ON MAKING AN INTERCOOLER ROUTING PLAN. So this will allow the install of an intercooler.

rx7speed

that turbo sounds way too small for your car

you would prolly be boosting at an idle

and you would prolly have to get it ported out to handle any decent flow or you would prolly end up choking the car to death.

,for my rx-7 I was running a T04 with no problem and the boost was able to kick in at about 3000 rpms
and also if you have the car setup right you should be able to run more then 7.5-8.0 comp

I was running around 8.5 at 12 psi

I know I could have pushed to 15 without much problem
just boost spike was killing my motor

and I know of a few cars running a 9.0:1 with about 12 psi also

and I have seen a few s2000 running 6psi and they have what 10-11:1 compression?

just make sure you get all fueling issues setup good and have good tuning and you should have no problem with it

KED85

IF I did.
I would extrude hone the whole top end.
Lower compression.
Add supercharger.
Centrifigal.
Use all the other TPI V-8 set ups as a guide.
90% of the guess work is done, that way.
What do you have to do with a turbo?
Add more pipes then I've ever seen.
AND IF I WAS GONNA DO A TURBO?
How simple can this answer be?
Go get a 3.8 Turbo motor and slap it under the hood.
You're gonna tell me you cannnot find a used Buick 3.8 Turbo?
They have got to be so common it's not funny.
Or just buy a wrecked 1989 Trans Am and do as Kyle did.
Fix it.
Way easier, way less money, way less custom hokey guessing.

Buy a proven design by GM engineered motor and spend the effort intergrating it under your hood.

Hell even a Syclone engine set up would be a plus to work forward from. It is a V-8 minus 2.

Camaro_hunter_d

Well I was gonna do the lower comp so IF I wanted i could upgrade later, or run a little NOS(75-100 shot) with it(and our bottom ends are not known for being the strongest in the world). And I sized the T3 maybe a T3/4 for LOW END. Thats where our cars need it the most. So Thats why I was looking at the 1700 through 3500 band on that turbo. That would allow you to run the turbo with a HIGH RPM BAND profile cam to squeeze the turbo a little more. Relying on the turbo through 33-3500 RPMS then the cam kicks in and opens the top end up. And if like me hit the juice and really begin to scream. I think that this set up SHOULD be good for around 13's on turbo alone. Maybe quicker who knows....

Not meant to flame or anything just putting out the info. AND by running that low a comp later I could create a twin T3 set up that would rip any 350 to shreads. And yes where I am mounting the turbo(s) you CAN mount 2 of them. The troble being then the intercooler(s)....

rx7speed

hey man I know there was no flame there
but if you want to tell me that a thirdgen is better then my maverick I would have to go tell my mommy on you cause it the bestest car in the world


I would say a T3/T4 or a T4 would prolly be best

I think it is a T3 that comes stock with our cars and full boost would hit by 3000 rpms I think with it starting to push at 2000, and this is for a single not a twin.
being that your motor is putting out a little more displacement I am sure it would pick up in the rpms a little lower.

if you are going to go with twins and want to pull the power up in the low rpm range then I would go with maybe twin T3 turbos

and n2o with a turbo




though you can always be like a few guys from the RX-7 forum and run a T-76 or T-88
and remember this is with a 1.3L car
