Alright, I found this pic while browsing the turbi technology website. I had originally went over there looking at header designs to see about welding one up myself. I was going to have a co worker do it. he used to build headers for a living.

Anyway, i ran across the kit that turbo tech makes for the vortec truck. Well LOOK AT THIS!!!


In my case, this is damn near PERFECT! It is passenger side mount, they make kits with T76 turbos so Im pretty sure one would fit. I would have to worry about a crossover, a drivers side shorty header and ducting to the TB.

Guys... I think this is the ticket!!! There are guys with the LT1 turbo tech kits on modded motors making 650rwhp so I think that says something about the potential of their stuff.






Im going to call them this morning and do a little bit of footwork. If this is even remotley possible guys, IM SELLING MY VORTECH NOW AND PURCHASING THE TURBO STUFF.

Alright got some more info guys.
I talked to George @ Turbo Tech. He said that the vortec truck would be as close to a fitting header as I could find. he also said that it is a log design.

He made it a point to mention that he thought I would only be able to make 650-700 hp with that manifold though. That seemed bogus to me because I know of one LT1 guy making 650RWHP with a turbo tech single turbo and a 383 with AFR heads, etc.

He said he had room to turn up the boost on the wastegate too.

So Im debating here. Should I or should i NOT go with this header?

GRRRRRRR!!!!!!

 

Header in action:

 

Im going with what dan said on MFBA. Besides, single turbos suck. Do duals like me and 89procharged. Dont you want to be part of the group Guido?

What is that much better about twin turbos? You double the heat under the hood, you take up more space. It becomes a nightmare.

Besides, a T76 will support the horsepower levels you guys want to make with 2 turbos so why not go with 1?

Just makes sense to me.
Im not even positive Im going to go with it. The fact that it will only support that much horsepower, while it has been exceeded, doesnt leave much room for improvment.

 

Twins are easer on the motor and you can make 1100hp on a 355 with two TO4 turbos and intercooler. My engine will dyno 700@14lbs on pump gas and 1100hp@20-25lbs on race gas when its all said and done.

 

What makes twins easier on the motor?

 

There is NOT twice as much heat underhood. You still run two headers with a single. Twins run similar levels of power at lower boost levels, have longer lifespan, and reach full boost at lower rpm. You can also avoid externally wastegating the units, which can be hard to find room, and is very expensive. The twins I am running will support 1000 hp, have internal wastegates, and reach max boost by 2800-3000 rpm.

 

Are you using twin super20G's or something?

 

1000hp?You better think abut getting a Bowtie Block.Im not a turbo expert by any means but to think to only be putting back pressure on one bank of cylinders,probably,two sides into one.What about the Callaway turbo Vettes?Doesnt Callaway sell the headers and turbos?Give him a call.
Guido,why are you dumping the Vortech?Turbo is a great power adder too,but a supercharger isnt a slouch either.You are talking very little differences in hp.I would think gradual increase in boost is much safer on a engine ,than the hit a turbo gives.
Why is everyone now interested in turbos?My question is not sarcastic,just want to know why?I have yet to see the hp differnces on the track or anywhere over a centrifical.Turbo is expensive to do,from what I am seeing,alot of custom work.Yes,the Lingenfelter turbo vette is very impressive,but it costs $45,000 ,and there is alot more involed than just strapping on 2 turbos,the price reflects it.
Guido,why dont you just build the motor and keep the vortech for now,its paid for.And what would a turbo give over a Vortech anyway?With a 406 under the hood you wont be strapped for power by any means

 

If you are concerned with the 1 turbo and single LOG manifold, then how about buying just another LOG manifold and running a twin set up? If each manifold can support 650-700hp then you are covered with 1300-1400HP. If you want around 700-800hp, you would still have pleanty of room to grow for future "MORE POWER" demands. Just a thought though. What size are the manifold primaries? Are they made out of Stainless Steel?

YOU HAVE A GREAT LOOKING CAR!!!!!
US 3rd Gen er's need to get a a company TURBO TECH or so, to develop a turbo kit for US!!! WE have more room than LT1's and LS1's, why doesn't anybody make one?

WE NEED TO MAKE OUR VOICES HEARD!!!

 

Well, personally, i have always loved turbos and dreamed of a twin turbo car since i was like 9 or 10. so i am going to do it. also, a turbo is more effiecient than a supercharger. not by much, but it is. also, haven't you noticed the numbers the pro's are running with turbos? now i am not saying that there are not others running huge blowers and tons of nitrous not winning. look at billy glidden, tony christian, and some of those mustang guys are super quick with those big D-3M's. But who is the quickest in Pro 5.0, uh Joe DeSilva with a big turbo. Also, look at rieger, he won the class in his second year. Does anyone realize that in most pro classes that nitrous and supercharger motors are allowed unlimited cubic inches, but turbo motors are limited to i think the mid 400's? also, if you run twins, you have to weigh like 3200. I like both blowers and turbos. i just like turbos better.
Guido, how much are those headers?

 

Although my turbo selection will support 1000 hp, I will be making less. No need for a Bowtie block. In fact, I have a tall-deck, Bowtie block for sale. It cost $3000 new, and is good for a 434" stroker motor. I will throw in a pair of custom Heddman Hussler headers, too. They are needed due to the deck height of the block. Taking offers...

The turbo tech header is 321 stainless and is $600.

I talked to George there and he said that since there are so many different belt configs on thirdgens, that he couldnt make a kit for it.

I am personally leaning towards this single turbo. Its easier, less hassle, and will provide the HP Im after. However Im not going to do it till next summer I think. I want to finish putting the 406 together, and then i am putting my vortech back on. When tax time rolls around, I will have enough money to put a speed pro ECU in my car along with #55 injectors or larger if I need them.

After that Ill decide what I want to do.
But I love the idea of a turbo. At least now I can say Ive done some research on it and know a few options.

As for putting a turbo on the OTHER side (drivers side) There is a header for the impala SS kit they make, and it may clear the master cylinder but m not positive. Also, there is the LT1 kit but the header for it, turns down on the front and puts the turbo down close to the block. It doesnt look like it would clear. Possibly space the sway bar down or just take it off? I dont know...

just some thoughts.

 

Ummm... What did it cost?

Steve

 

I posted it last post...

 

Sorry, I meant cost of the entire kit. Just curious....

Steve

 

Oops.

Im not sure. I know all those parts would not fit. Hell, you have to have all your air diverter valves, water diverter valves, and all that **** out of the way for even this header to work. Thats the only way it would work I think. But I think if your going to the level of putting a turbo on your 3rd gen, you already have that **** gone.

Besides that, the downpipe from that kit wouldnt work. The intercooler and piping would probably not be a direct match. Just too many things different.

 

Take a look at the header for a Impala SS from turbo tech. It appears to me to be a mirror image of the vortec headerexcwpt it mounts on the drivers side. I am going to buy one of each sooner or later and do a twin turbos set up on my Vortec motor in my truck.

My thoughts...

Single turbo setups are easier to plumb, especially when you're using an intercooler (which should be always).

Schedule 40 iron pipe is available in 45 and 90 degree bends, both standard and tight radius bends are available. It is weldable and much cheaper than stainless and the wall thickness allows it to live. You can run a crossover tube under the engine from the stock drivers side manifold into the passenger side manifold where the outlet would usually be. See www.sdsefi.com for a manifold they built out of the iron pipe. For the difference in price between the manifold you have posted and the cost of the pipe bends you can buy a mig welder and enough pipe and bends to make headers for everyone on this board.

Speak to someone like Precision Turbo or Turbonetics about sizing a turbo properly. The newest generation of turbos can pump more air more efficently and with less lag so don't even consider a junkyard turbo unless you're trying to win a bet (I can run 10 second Ets for under $500, etc...)

Ok time to bring this post back up.. will that turbo tech header work, the dang thing is up to 700 now and maybe if anyones interested we can try a small GP im definetly going to be getting one in about a month or so which should give anyone else time to get up the money, and what trouble will i have getting that in my 86 along with the 93 LT1 i just got ? Hehehehe.

 

Guido, are you sure the Turbo Tech header will fit in the f-body engine bay? from the pic, it looks like the turbo mount is spaced away from the valve cover by a good distance. my gale banks manifolds have the turbo positioned right atop the valve cover and i don't see where there'd be much room to move it toward the fenders... just a thought.

I think that i am going to buy a chop saw & a welder & give it a go. my logic is that i can buy the tools & build mandrel bent tubing & do it for about the same cost. I am goign to have to do all the intercooler tubing myself anyway so why buy the header (to save time i suppose)?

from the second picture it looks like it will work fine, just have to plumb up the output of the turbo to the input to the TB.

how you planning on conroling fuel, by the way?

You guys are forgetting the biggest factor in the single turbo vs. twin turbo debates. The COOl factor!

Face it..not many of us are going for more than 500hp or so. you can make that with NOS, roots blower, centrifical, or even a screw blower. The biggest reason to go with a turbo over any of those is the COOL factor! And what could be cooler than one turbo...than 2 turbos!

I am following the turbo scene in the inport world..I own 2 camaros though so I have an american heart...I just love the way they get their power...turbos!. There little marvel can produce mad power and only drain 5-10 percent to make it, unlike the superchargers that take up to 50-60 percent.
Now the 1 verses 2 turbos'...You can get 1 big turbo and make just as much power as 2 small turbos...2 big turbos will suffer mad turbo lag and not be effective.
I read an article recently in turbo and high performance where they pitted 2 turboed supras against each other 1 single the other twin. To much the disapointment the single had more power overall and more power in the lower-mid and upper range. It could simply spool up faster and support more boost.
Now twin turbo while is cool has a ig disadvantage...money...twice the pluming 2 turbos..ect ect.. Right now I am looking at building a single turbo garret t06 4.3...I am looking for power in the range of 500 at 8-9 pounds boost and much more at the racing setting of 25 pounds...Yes I am going all out and building it to habdle that much boost...
I will love to take out any 8er around on the street with a 6er...I will just think its funny... thats my .02

 

Guido,

did you ever get one of these headers? have you started on this project?

Nope. Not at this point.
I may do it a little down the road. One step at a time for me. Im trying to get my car to run right at this time.

 

what are you running? I think that you are running a 7730 are you not?

I like the single turbo idea too. Its cheaper, less upkeep when time to replace the turbo. v8s are very torky so it won't lag on the low end like a Japanese car would. Look at Grand Nationals. That should be proof enough for the single turbo debate.

How does a single turbo bolt up? From the looks of the headers, it looks like it would connect on one side of the car!

Wouldn't that cause a huge difference in the pressure and scavenging on one side of the head, as compared to the non-turbo side? Doesn't seem like it would be all that healthy to run if you ask me. I think with duals at least both sides are symmetrical, or at least closer to it.

Or am i wrong, does a single turbo bolt up to a y-pipe of some type, where the headers meet?

Hey Bubba, all the parts are there. check out thier web site & you will see. they intend that you use thier Driver side manifold & use the crossover pipe (that they provide) to come up to the Pass side manifold that is in the kit. then you mount the tubo on that. & run the single down tube off of the output of the turbine down to your exh.

Pretty cool really. I talked to George (the owner I believe) & thought he was going to send me one to do a trial fit into my 2nd gen, My buddies 1st & 3rd gens, but he never did, Oh well, guess they have too much business to want to have 3 more generations of of Camaro users.
