I would try build a turbo on my engine. But I don't know anything of a turbo.
So I hope this could with the know how of daves12secV6 and other people.

To daves12secV6
Your turbo runs this on 3 or 6 cylinders? And why have you done this?

 

the turbo runs off all 6 cyls,if u only run it off 3 the engine will not run right,not to mention it would take forever for the turbo to spool up/kick in.
now if u ran 2 turbos u could run one off 3 cyls and the other turbo off the other 3 cyls

 

Have you pictures of the exhaust manifold, both sides to the turbo?
How you have made it?

To daves12secV6

Have you changed your ignition system for the turbo? Or is this still original?
Because the ignition timing is also important for the turbo!

 

u can run stock iginiton upto 9 psi,but after that the stock stuff becomes to weak.the stock timming curve is very conservative,so u really dont need any kind of timming retard untill u get into higher boost levels.i actually run my current engine at 10 psi with +4 aditional degrees of base timming,though i do aociasionally get some detonation and pinging.if i weree to back it off 2 degress it prolly wouldnt ping/detonate at all.

timming also depends on octane rating as well,the higher the rating the more timming u can run safely

 

Where have you placed the boostcontroller? And have you a maunual or electronic boost?

How many miles have your engine runs since the turbo setup? And have the engine always runs on 10 pounds of boost?

 

i have a manual boost controller,its mounted under the hood,ive got about 15,000 miles on the engine with the turbo on it,this engine has always run 10 psi

 

Where exact under the hood? And what does it do the boost controller?
Have you maybe some picture?

 

its mounted nexto the battery it connects to the wastegate and allow u to turn the boost level up or down without changing the springs inside the wastegate,i dont have any pics offhand but i can take some tommorow

 

Yes, I had gladly pictures of the boost controller and the connections. Thankx

 

Have you also the original cylinder head gasket on your engine or have you a copper gasket?

 

stock gaskets,there is no need for copper4 head gaskets

 

Dave, have you the stock exhaust manifold or headers?
And have you the stock ECU chip or an tuned chip?

 

i use the stock ecm and chip,but i also run a mass airflow system,since ur car is a 3.1 u have a speed density system,i am unsure of how well it will work with a turbo system in stock form.
i have stock manifolds,though on my new engine im am building foward facing headers

 

dave i was wondering where d u have the maf located?

 

its mounted on the inlet sude of the turbo,i have a aprox 8inch long tub that goes to the turbo inlet that makes a 45* bend at the end the maf is hooked up there,with an air filter hooked to that.look in my howto thread i belive there are some pics in there

 

dave on those forward facing headers u got them in the work and also are u gana be selling any?

 

possibly but there not gonna be cheap

 

well i was thinking about building some off fwd manifols do you thing that will work. because i wana take a weekend to do my turbo and i dont wana be working on the headers forever

 

Even with extensive mechanical knowledge, it's quite a project! My mechanic even thinks I'm crazy for putting a turbo on the 6! I have him do all the "DIRTY" work (anything that will pour fluids all over my driveway). The best thing to do is have all the parts handy (even some extras) and a friend to help won't hurt either. I'm still up in the air 'bout the twin turbo setup since I'm running a MAP and not a MAF. If you run a single setup, you can use your factory manifolds and just get a y-pipe from dave.
For all of you, I've found a website that has cheap mendrel bends in all sizes, including header kits and intercooler kits that start around $45 USD.
Here's the link...

Here's a link for silicone connectors and clamps...

Both have lots of goodies that are better quality than e-bay perhaps.
Lookin forward to having someone doing this build at the same time as me!

P.S. Welcome to thidgen!

 

im unsure of what the fwd manifolds look like,but id have to say the easiest way is to build the under k-member y pipe like i did.its cheap very effective,and dosent require welding to cast iron,which is hard enough in its own,u have to use nirod,and even then its still a bitch to weld

 

I'ts easier to make a mild steel plate to bolt to the head, welding cast isn't easy even for my friend who works at a CNC machining factory!

 

well some of the manifolds ive been looking at are mild steel

 

Why don't you do this

 

id love too but way too much money and time for me right now

That's SWEEEET! Got a couple of questions, 1.What size turbos are those (I have a pair of a/r .48 exhaust.63 I was thinking of using)? 2.No wish to use an intercooler? 3. Is that a 3.1 w/ a speed density? 4. Did you build your own manifolds, and how hard were they?
----------
Wouldn't cost any more than your planning to spend now! If you don't use an intercooler, you could use that money to buy another turbo. The major concern would be building the manifolds, but the intake side is simpler.

 

Haha, calm Firstfirebird. That is not my car or engine. I saw that picture and was very impressed by it so I saved it. If I had the money and knowledge to do that, i'd definetly share it(only the knowledge though).

 

If my memory is right thats not even in a camaro. I doubt if youd have enough room on the sides to mount the turbos there.

 

Yeah, I got so excited that I wrote that before checking out the pics of YOUR car, haha
BTW, your car is sweet too...

 

I think there is enough under mine (Firebird). I was hoping to talk to someone about twin turbo. I mean daves12secv6 has been awsome about answering questions, but he's using a MAF setup and I need some answers on a MAP system. Does anybody know if the twins could be run into the intake (before the MAP) or would I have to run the MAP BEFORE the turbo (like daves)? I already have some turbos and the guy who gave them to me is really pushing for the twins (he has a tt300zx). He said I would be the only one around to have them, but now that I saw that pic from charcoalbird I see that SOMEONE has already done it, and I like it!

 

You might, I dont know that much about the room that the Firebird has.
The MAP sensor comes out of the back of the upper plenum. Also I just read that you could keep the MAP and stock chip if you ran a FMU.
