Home made STS Kit?
coming from you doesn't sound very promising... please advise. I don't plan on having it put together in a day or a week.. nor do I plan to have the parts tomorrow... I was kinda hoping to force myself to pay for it as I go so I don't just shove it on a CC... Also i think if researched and done correctly it could be done for far less. But i could be way wrong... hense why i posted here... You guys know best.. but i think many of you have deeper wallets than I.
You state that you do not fab stuff yourself, you farm it out. This suggests that others will be, in effect, building the kit for you.
If that is the case, it will be A> Much cheaper and B> Much less frustrating to just buy a genuine STS kit.
If you had a machine shop - or direct unlimited access to a machine shop, along with the requisite skills, talent, time and patience - I would say "go for it and please post lots of pics of your progress"
Let me put this a different way; if you were into superchargers - you might look at the ECS Paxton or the A&A Vortech kits and say to yourself "they are just a few brackets and a couple of tensioners" right??? Wrong.
What you are paying for - besides after sales support - is their R&D. The ECS & A&A kits bolt on and run effortlessly, flawlessly, without fanfare or issues for thousands of miles on stock engines. Same with the STS kit and most of the well designed TT kits.
That R&D is not cheap, nor is it easy, no is it fast. An example is the (soon to be released) APS TT kit. They have been testing their kit for months - refining, honing, getting all the kinks worked out....
And that's just testing. Who knows how long they spent on the initial R&D, the deep research and design that got them this far where they are almost ready to offer it to the public.
A Paxton or Vortech head unit is circa $2000 retail. Some people look at that and think "why should I pay $5k+ or $6k+ for something that costs $2k?" But what about the "ancillary" parts? The J-Tube, BOV, FMIC, tensioners, routing, alignment, relocation, oiling etc.. etc. etc. etc. etc.
And what about the after sales service? The guarantee (for want of a better word) and the reliability?
Building a kit is much more than buying two Garrett turbos and some piping, throwing it together and seeing how it works.
I, personally, do not have the skill, talent, will, know how, knowledge - call it whatever you like - but I know my limitations, and I do not have the ability to build a forced induction kit from scratch. I tried it in the 80s and the results were very mixed. I have since learned my limitations.
So, like I said - "Good luck". I meant it with absolutely no heat.

I mean cut the bends and weld it yourself.
If you have to farm out to a shop anything you save if going to eaten up with their labor for making something that is one off.
The reason that there are not other shops "making the same thing cheaper" is that supposedly Rick Squires and STS hold a patent on this rear mount turbo system. Now if you make one for yourself... I would not be worried about it. If another shop started making them for sale, I am sure something would be done about it.

now tell them to get blue off teh dyno an let my lil wussmobile on there...
As far as DIY this is the simplest application for C5 IMO. With that said look at or do some searches on this forum and learn/guesstimate A/R ratio... it's not rocket science.
Read up on heat retention and other details, study thermodynamics and take it from there. Don't fall into bigger is better mindset because with rear mount it will hurt you much worse then front mount.
If your competent at welding/bending/fabrication consider it a mild challenge.
Good luck,
Mike
And that's just testing. Who knows how long they spent on the initial R&D, the deep research and design that got them this far where they are almost ready to offer it to the public.
Once the extensive testing program is complete you can expect a reliable twin turbo system that produces high power and torque combined with high component durability.

On the other hand if you are a fabricator, or have the experience and the equipment, then you might save some money. But you also have to look at your R&D time as an investment too.
The exhaust part is simple, and the charge tube probably isn't that difficult. I think your biggest problem will be the oiling of the system in the rear. Even STS has or had problems with this. And I am sure they have made huge R&D investments into that area.
You should price all the component and material first, then see what you have to work with to save anything. But I think you are going to open up a can of worms trying to do it yourself. And in the end, you will probably wish you just bought a kit that someone else has did the painstaking learing curve for you.
But building your own kit would be fun no doubt if you have the skills though. Good luck if you go that route!




I can tell you for a fact, that there is HUGE amount effort (time, R&D, Q&A, capital) to develop well a working kit vs. something that tossed on the market on your dime and pain and suffering.
The margin is simply not that high for any manufactuer, hence many rush to market to early. Someone that is going to do it one off, you are going to have your hands full over years. There is some serious talent here, but they always start with something.
How were you going to make the rear mount wiring harness?
STS does a have rear mount patent.
STS does have patent on its oil system.
The STS Corvette instructions have a 2004 copyright.
