buliding single turbo header and have a question about header design.
I got the headman shorties for a f-body to start with so the drivers side is done and wraps around like the old bbs kit. I have the other turned upside down and have cut the tubes off and can make it all fit with the a/c fairly easy,BUT then no room for a 3 inch down pipe, well not much. I was wondering how much of a power loss if any would after coming up from the drivers side I stepped up to say 3 inch pipe and used it as a log and just piped in the pass side so I now only have one pipe up and lots of room for the down pipe back. It just seems that if you run a standard header on one side that running the other just into the flow it would make the two sides of the engine run different. Like running a shorty on one and long tube on the other, you would never do it. I know the bbs stuff is like that but really that is the reason I didint do it plus I want the turbo mounted down where the factory air can was at on my formula. Plenty of room there(where mustangs mount them too) and away from the a/c and valve cover but down pipe tie in to the rear becomes a problem. If anyone has done this and has pics that would be great to give me an idea of where to go with it. You can do it a bunch of ways but I dont want it just done but done right. I have a t-76 turbonetics ceramic ball bearing turbo now for those who told me not to go with the smaller master power t70. It would be so much easier to not build a seperate header for the pass side and just log it in but I want it right. If that is fine then I am all over it but want some people making good power and that have run it like that for a while to tell me not someones general opinion on it. Pics of some combos would be great if anyone has done what I am thinking of doing or just what you have done and it has worked out for you. I am keeping the a/c but will make new lines to go around it if needed but nothing is getting moved on the engine and of course the smog pump is gone giving more room there.

Re: buliding single turbo header and have a question about header design.
Put the turbo where you want it. Keep the D. side header as you have it. make the crossover and P.side however you have to to mate to the turbo where you want it.
It really is that simple. logs/manifolds/custom headers are only gonna make a little difference. So make em to your liking and run it and have fun.

Re: buliding single turbo header and have a question about header design.
besides on a mild setup the biggest restriction will always be the turbo not the logs, manifolds, etc.

Re: buliding single turbo header and have a question.
I guess that is what I needed to know. I just wanted to be sure it wouldnt affect the performance of the engine. I am sure you know how the bbs comes around and connects to the drivers side. Now take where the turbo is with that set up and move it down(chris where you had it on your vette manifold set up) to infront of the radiatior catch. If I tie it all in at that header then run a single pipe up to the turbo is that ok or do both pipes need to merge at the flange?

Re: buliding single turbo header and have a question.
actually I m wanting to do it like the factory tta set up but continue the pipe farther away to mount the turbo up front. mounted where this one is(chris did this) and using this style for a v-8 moved way down.

Re: buliding single turbo header and have a question.
wow that is cool. I could do something like that on my 94 z that is a race car. the lt1 would be good for a similar setup minus turning the intake. I am working on a hot header now. Down pipe is the biggest problem other than dumping it right down. I am going to have to get creative with getting it to the rear. Other than that going pretty well. will put up pics when I get done.

Re: buliding single turbo header and have a question.
A buddy of mine has a 66 chevelle big block twin turbo that has a intercooler set up like that but the size of the pass compartment. I think it holds dry ice. It is a 2500 hp car. I think twin 88mm. Super nice car too. Was restored then cut up. I hated to see him chop up such a clean car but it was a 283 car nothing fancy just super nice. Now a super nice race car. Well I spent 2 hrs and came up with this really quick. Leaves me alot of room for a down pipe and the other side to merge. I will place it down front and come over the top with the pass pipe like chris did. Should work out good and the nice thing was the header I cut up, I used all the pipes from it but one small piece off another I had here so actually used both headers in the kit I got so no waste. Look ok??

^ You have to cut and paste the new link, the one linked as a thirdgen attachment, otherwise you'll get that message of already posted. Like this, here's an already attached picture (from a few posts up), but with the new link;

Re: buliding single turbo header and have a question.
Its all good now. I have most of it done but now have a few questions in two new threads about the intercooler and bov set up and the waste gate set up if you want to check them out and see what you think. I have the hot side all in am going to start welding it all up shortly. I just need to pick a few spots to make it able to come apart easily for working on the car.
