Yep piecing one together. Im going to take the middle of the exhaust manifold and take it to a exhaust shop or somewhere and get them to make it out of Stainless and get them to weld a T3 Flange on it. When I was at school I did a dyno simulation on the computer of the 3400 with a T3/T4 and it "theroetically" made 362 whp on 6psi. Stock internalled. Of course I will have to rearrange where my pcm is and wires and what not but it should fit the way I crapply drew it up. Its just a rough sketch lol. What do you think?

Money,,,, kachinggggg.
Then you need some bigger injectors, bigger fuel pump, intercooler, piping, silicone parts are high priced for what they actually are. Will your ecm handle boost tuning?
I am there, What I thought was going to cost a reasonable amount for twin turbo's on my s10, doubled.....
If you have the funds, go for it. I would have to say it would fit there, going to be tight on the down tube though and thats alot of heat for the mastercylinder, but It should work.

Here's what I think.
On the stainless part. Especially since it'll be holding the weight of a turbocharger, I would maybe check over in the boost forum and see what they think of it. You don't want to use a material that's going to break.
Unfortunate part is that on the 3400 you cannot take a front exhaust manifold, flip it over and put it on the back side. It doesn't fit that way. I think what some guys might be doing is juat having a blockoff made for the rear manifold and then having the crossover pipe modified for a turbo. Might even be an easier way to go.
Oh, and 358whp @ 10psi on a 3400.

I'm not saying you can't make that kinda power, because I know of that 2Gen build. Johnny (the link I posted above) had his on the dyno and it ran 299whp at 11psi. He's using a t3/t4 turbocharger. He has a built engine as well, I can't see why he isn't pulling numbers like that 2Gen.

Probably in the tuning. IIRC that 2nd gen is using modified 3.1 Turbo code in the ECU.
He had it tuned on the dyno, he is using MSII

Its because johnny was using the stock cam. Hopefully it will be different this year. I can see 400 hp from that engine in a few months.
could you not use the space that you have setup for a block off plate for a wastegate or BOV?

I think theres alot of potential with this 3400 motor to put down some good power if not push it into the 12s on the stock bottom end. I have already priced it out and it will be reasonable. Good idea though right?

As far as the Stainless goes I was just throwin that out there. And My injector duty cycle at WOT is only at 70% so i have some tuning there as far as the turbo goes before I get to 80% and have to get bigger ones.

You could probably get a set of GTP fuel injectors when you go boost and be ok. What upsets me is how for the same engine at WOT your duty cycle is 70 and mine is 112.
I do like the idea. The typical setup of the turbo on the 3400 is off of that crossover pipe. Though, don't forget to include a battery relocation kit as part of your parts list for the turbo setup. It will need to be moved.
Battery has been relocated for some time now.

Well, then that solves that.
Steve is correct, I had forgotten that Johnny was using stock cam. I was talking to johnny a few weeks ago, and he has the engine pulled apart right now to check everything over, installing a new cam (not sure on the specs), I think he had the compressor side of his turbo machined out and a bigger wheel put it in, and he's upping the boost to 15psi for this season.

If you are getting a crossover pipe modded why not use somthing that will support the weight of a turbo better? Can't remember what its called but (Skeg 10 I believe) its used for gas fitting, find that and use it to do a crossover pipe, it will suopport the weight better. Another turbo you might look into is the Holset HY35(off the '02 Cummins rams i believe).
I'd rather drive an A than push a J...
another option for the headers is to make a log style one (sorta like the ebay ones for the 2200) but make it out of stainless elbows here is a link to see what im talking about they are a little heavy but you will not brake them... I have a friend with a 650hp Honda civic with a header made of this stuff and he cant brake it. good luck and keep us posted. I want to do this swap also so its nice toe see the progress and it looks great!!!!!!!!!!!
