I was just browsing through Summit, and ran accros these. Maybe everyone knows about them already. They are the S10 v8 swap headers, I've seen pics of some other types, but these look even more compact. anywho here they are. Looks like they could work well with turbos.
can't post a link, just look in the header section for S10 v8 headers.

 

awesome....i've never seen those. I'm going to go check on price.......and maybe i'll see how they work on a motor like mine

Not too bad for $280 but i could build some for less that would fit better

 

what he said

 

I was looking at a set of stockers off the 82 cross fire vette as a set to help me make a nice single set up.

 

Thats really interesting... Granted someone could build them cheaper IF they had a welder, but someone like me who doesent, 2 t3/t4 flanges, slight modifications, and a trip to the local welder/exhaust shop could have those headers ready to go for about $400.

Then comes down pipes, turbos, intercooler, plumbing, etc etc... I say about $1500 if you do all the work besides welding... not a bad investment if ya ask me!

If I come across some extra money, Ill pick up a set of those and test fit em... if it looks like they wont work, Ill send em on back to Summit and lose my $8 shipping.

 

After some thought, I doubt these headers would do any practical good. If the flange were to be mounted at the front of the header like the design suggests, then it would be impossible to use the factory accessory brackets, and possibly heavy hood interference.

They do have the basic design of an easy to make turbo header, and after some more thought (talk about friction in da brain!) like some said above, a set that fits better could be built for fairly little money.

 

that has got to be the nastiest flowing aftermarket headers i have ever seen

 

This is Lingenfelter Twin Turbo Corvette headers:

 

I think the regular 120$ hedman s10 swap headers would work much better.

I am thinking about doing a single turbo setup and running a s10 header, flipping it and welding the flange on...just need to figure out what kinda turbo I need.

 

I bought the hedman's, test fitted them and hated the way it looked. You can make it work (since it has been done) but it looked like there would be some clearance issues with the steering column IMHO. They aren't very symetrical either and i think it would be tough to make it look very presentable.

The stock exhaust manifold conversion is super clean and nearly free. I'm looking into this now.

 

If I do decide to do this I'm not gonna be running the turbo on the drivers side just the pass. side.

I have seen the drivers side done but like you said it looks like a nightmare when it comes to clearance.

 

just running a single turbo off of one bank sounds like a nightmare for tuning cababilities. i would look into running some type of system like the BBS designs system, that way both banks are feeding the turbo.

too big of a turbo running off one bank will take to long to spool, too small and you won't make any boost.

 

Is this the type of header superirocz used in his twin T3/T4 setup? I couldn't make it out for sure in his pics.

 

Yup, he used the hedman shortie s10 headers.

 

A set of stock L98 manifolds converted to twin turbo headers;
got the idea from someone on the board, and it worked out great.

turbos fit under stock hood too; and these are larger than GN turbos (TD06-20G)





the L98 manifolds are CAST STEEL, I used the same nickel/cast rod that Nasa uses (210,000 PSI) from what Im told it will last

 

Or you could just simply buy some turbo headers designed for the thirdgen to begin with, which fits and is merely a bolt on. www.bbsdesigns.net sell them for $545.

Also got twinturbo headers. They do have complete kits too. Check it out.

 

545 dollars is no small amount when you consider the L98 exhaust manifolds will work nearly as well and are free or nearly that.

 

THat's true, but considering some people don't know how to weld, it's cheaper than buying a welder and a welding course.

 

If you had a set of L98 manifolds, or even if you didnt (what $30-$50 on ebay?) You could take them to a person who DOES know how to weld, with pictures of what you wanted and maybe even the materials, most people know how to cut up steel right? make the pieces up then get them welded. Crap like this is cheap to get welded up, originally I was going to have a friend TIG weld the manifolds, he wanted $80 per manifold but I played around with the Arc welder and found it would work perfectly fine.

I mean, i guess to each their own. if you cant weld, and dont know where to get something welded, or the material, you really dont have much option then do you?

Someone with at least some fabrication skill shouldnt be afraid to cut and gut some crappy stock manifolds though, I mean even if you screw them up what did you lose? All in all I spent $50 on the manifolds / materials and welding rods. $50 for a set of twin turbo manifolds, is not bad in my opinion.

 

No, I don't mean to bash your job, I would love to have them. But for some people, like me, those manifolds aren't plentyful, so it would could be easier to just buy something, than to spend alot of time and at least some money for something that I suspect isn't quite so good, and don't fit as good as the finished ones. Anyhow, it was just a tip. If you can make them yourself, it's not a problem then.

 

Kingtal0n, you’ve been busy… looks good. I’m surprised that you didn’t just weld the air fittings shut while you were at it. I asked you this before, but I don’t remember seeing an answer, how did you come to the conclusion that they are cast steel? The rod you used would work on either.

A few points…

Don’t worry about L98 manifolds… any V8 3rd gen manifolds will work fine. The biggest difference between them is the size of the outlets which you cut off and blocked anyway.

As far as flow, with the right turbos there aren’t many small blocks that you won’t be able to blow up with those manifolds, flow really isn’t an issue, and the castings having heavier walls is an advantage from a durability and heat retention perspective.

Finally, finding someone to do it shouldn’t be a big deal, TIG is WAY overkill and probably not even a very good way of doing this. If you brought me all the parts cut and fitted I would probably weld it up for you for $50, probably $100 if I had to do the cutting and fitting.

 

Not trying to burn anybodys bottom but there are a few statements in this post that must be addressed form a design/engineering/physics standpoint...Even though Lingenfelter used roughly the same design as the headers in the first picture, I would not call those headers "idealy designed". The 90 degree joints to the main body actually impede (somewhat) the flow from the exaust port infront of it; to look up the reference for the basis of this effect look up "Laminer Flow". This is especially important when using forced induction because more air=more end gases that have to be successfully scavenged from the cylinder. Stock Manifolds and the aformentioned header will function but they certainly will not allow for max available power with a given forced induction system. Sorry if I strayed off topic...just a little bit of power theory for eveyone to think about. Like I said before, not trying to flame anybody...just take the info for what it is worth...Thanks.

 

Im pretty sure your wrong; im just going to let Crossfire tell you why your wrong, maybe if we were talking super chargers... , Its GOOD information, I agree stock manifolds = crap for power in most cases... Lingenfelter was no fool he knew what he was doing.

It was explained to me, I think I understand it, but my explaination would be less than adequate at this point.

 

that bbs header is $575 for JUST THAT ONE SIDE.

not both sides and crossover.

 

I do believe that it doesn't matter too much what your headers/manifolds look like because the turbine of the turbo is going to be the biggest restriction regardless.

Now if we're talking about pulling as much power as is possible, sure tuned equal length headers would be better but kingtalon is going to pull 600hp out of that setup with ease and not too many people need more than that.

KingTalon:
What exactly did you use to weld those up? I'm starting on mine this week and hopefully will be able to document it with pictures as well as you did. I have access to an arc welder (what rod?) as well as a mig (wire?)

You made the rectangular area between the manifold and the flange but is there not a piece of stock bar that could have worked there to save you some trouble?

PS: my manifolds are in the mail. $10 plus shipping

 

Im pretty sure all the information you want is in this post: https://www.thirdgen.org/techbb2/sho...0&goto=newpost

if it isnt, leave me a PM or add a post to the above post and ill help you as best i can. I dont think the rod/wire information is there yet though, i just got back tommarow ill find out.

 

Hi Guys,
Probably some of you may find my headers expensive, but when you consider that they are made of laser cut 3/8" thick steel flanges, 1/8" thick pipes, all TIG welded and they are all designed to be used with operating A/C, then is not really that expensive. The street and strip TT design even lets you keep all the power accesories, not that bad isn't it? The best way to understand such thing is to try and make your own headers; figuring out turbo position, down pipe clearance, wastegate location, the cutting, the grinding, money spend, time spend, etc... and finally contemplating what you end up with.
I am not hitting on anybody with this, just defending my prices

 

no one complains about your product BBS. I personally think that you have the finest turbo headers I have EVER seen. I would have surelly bought them if i had the cash, no doubt in my mind.

problem is, when your budget for the entire project consists of what your asking for 1 header I didnt have that choice, i had to make my own. I spent about the same on my entire project as one of your headers cost; simply because it was all i could afford right this instant. In the future when I do my next TT project, (there will be another) I will probably go with a set of your headers.

 

Hi KingtalOn,
Thank's for the complement
In that future project are you going with the street and strip TT kit or the nasty race TT kit I bet you are concidering the nasty one now that the A/C is gone aren't ya.

 

well my "future project" isnt going to be with this car, i may end up selling this car and starting with a new thirdgen. thats way down the line from now though, i hope your still around by then.

for now, i have what i want, a TT camaro. in all its glory too, oil leakin and turbo whirliness. so budget minded I used duct tape instead of silicone hose in one place. LOL thats getting changed soon though, dont worry.

 

I don’t think that you have any reason to defend your prices… When you take into account the labor involved and the materials needed your prices are quite reasonable, I believe that they are right around or just under what I suggested that people would have to be willing to pay to get someone building them a while back (mind you people thought I was crazy and I basically suggested that in the next few years as those of us that had 3rd gens as our first cars get old enough to have a little money that someone will probably turn up and start selling them in about that range).

To be honest, I’m still wondering if your making enough money on them to keep building them long term…
