Hey guys,

I need your help. I need you to post as many pics possible of just turbo manifolds for both TT and Single turbo systems. There is a possibility that with the appropriate time and R&D a manifold can be designed for these applications for the DIY turbo kit builders.

Any and all pics will help preferrably of the flange, bends, and welding points. We are going to based of design around what some of the others have done and see what we can come up with.

Help us out and we will see what we can come up with.

 

are you in the process of trying to make a custom fabricated turbo kit?

 

 

The problem with makinf a do it yourself universal turbo kit, is the variances in different turbos and configurations.Look at the PE,Greddy,APS and JWT manifolds, all use different turbos,all manifolds are drastically different.

Right now.. I am working on a Single Turbo manifold. I understand what you are saying, but in that case theres a pretty easy solution. The way I look at it most people will be interested in GT series Garrett turbos. Now, anything below a 30 is going to yield a lot of hp (300s). My interest at this point is the 42. If I can manipulate a manifold and turbo of that nature in there, then smaller turbos should be a breeze. I know you have seen them all MRC, can you help me out?

 

If that is the case then simply start with a good equal length header design and rout them together to the turbo location making sure all of the tubes are equal length.

 

I thought about an EL design, but the downside to that is spool time. Can you suggest any quality equal length headers on the market? I want to route the turbo down low toward the short block A. that will give me more room to route the other manifold to the turbo and B. Ill have more clearance for less bends in the downpipe.

I see you make a good point, the difficulty is going to be making a collector that mates perfectly to the cut-offs that we would make to the header.

 

The TN single T kit uses the stock manifolds. From what I hear, those kits are really efficient and make good hp. If I was going to try to fabricate a single kit, I would follow this idea. Their turbo placement ideal in my opinion because you don't have to run a sump for oil supply like in the APS single T kit. Just find a more efficient way to route the manifolds together and maybe intercooler piping with less bends. But like I said, that kit works really well from what I've read.

 

Good case in point BUT!.. The stock manifold is VERY restrictive. Its 1.25" diameter opposed to most 2-2.5 for some manifolds. There are better manifolds to be had, but a manifold designed like that would be ideal. to get the turbo lower. Shorter oil feedlines= good!

 

Bottom line is, it is very cost prohibitive for the average joe,unless he is a master fabricator,to come up with his own turbo kit.

 

I have my sources...

 

pcv tubing mock up, basic welding , band saw, measuring tape, 180, 90, 45, degree mandrel bent tubing and donuts from a ton of online stores can go a long way.

plus you can learn a lot from a DIY. priceless...

 

you have a good point. Once the simple design is down, then all you need is a good mandrel and tig welder and your set. I have those connections already.

BTW, I stumbled across this on my350. http://my350z.com/forum/showthread.p...=1#post2549966

Im getting closer.....

 

Not to bust your buble, but by the time you purchase a set of SFR manifolds, which are their design for their turbos, then purchase similar turbos and make all the SS piping, and intercooler, your right back to square one..Which is purchasing an already made,no headache turbo kit that someone else already planned out.Im not trying to bust your chops,and I wish you luck,however in my professional opinion there is nothing the average joe is going to duplicate that performs as well and is cost effective as some of the turbo kits that are already on the market...Not saying it "Can not" be done, but its going to to take alot of your time and money doing your own R&D..

 

If I had the money (and I don't right now), I'd like to take the TN kit and fit a verticle flow FMIC. I'd think it'd be a little more effiecient. That kit is supposed to be compatibale with aftermarket headers, but I think the thermal properties of the stockers are better then the aftermarkets.
