Well if you have the internals and engine modifications figured out already just by selecting a bunch of parts off of VACs website good luck! I'm telling you you have a lot more to do than simply rebuilding the motor to be stronger, bolting on a manifold and turbo and getting it tuned. It may seem that easy but if you want better than OEM or even OEM reliability you are going to have to do more than simply throw some parts at it and up the boost. On the other hand I realize Im a picky b@st@rd and have to have everything perfect, so what Im looking at doing and what you want may be two completely different things.
As far as tuning since it seems you are looking to keep the OEM ECU I would try and get ahold of Mark Dsylva or E.A.T. Enhanced Automotive Technology he is local (I believe) to you and has experience tuning the S38 (NA chip burns) and most people seem to like his work. Good luck man, looking forward to your progress!

So what should I do to make it oem reliable with boost?
sorry.... but it will NEVER be OEM reliable..... no tuned car will be, unless you spend some millions on it....

Internal stuff of the 3.6 is very good ,,, strong and quality materials
but you have to lower the C.R.,,,,,, 8.5 is a populair cr that many use,, i would never go more than 1.2 bar,, more boost ,,,more tremendeous heat are made from the engine
another intake box is needed,, new software,, new exhaust manifold,, new fuel system
this is a //$$$$$$$$$$$$$$$$$ project
her is a picture from a S38B38 engine ,, in a E30 M3
800 horsepower @ 1.8 bar ,,,,,,, that is a lot,,and the car is easy to drive

Hum why do you say it would never be OEM reliable? Granted OEM's do have a large R&D budget but at the same time they do have to build to a budget. So if you ask me a proper build up of the engine (Internals, electronics, heat management, lubrication etc.) for forced induction coupled with more modern technology and practices I don't see how OEM or better than OEM reliability can not be attained.
It simply comes down to research of the areas of the engine that are under more stress due to the turbo application and then applying reasonable and well tested parts and practices to increase the engines ability to cope with the new stresses. So yes it does take more time and lots of research and usually more money (not millions) to make it OEM reliable but at the same time its far from impossible. Just my 2cents and hopefully my build up will be able to accomplish it .
Ferrari-BMW is that your car by any chance? Also why do you think an aftermarket manifold is needed, does the OEM unit become overly restrictive above a certain threshold or what? Thanks for your input.
you will never get OEM reliability because you dont have tons of engineers working in your project, neither safe and quality tests.... so, a little thing can ruin it all.... hope it doesnt, of course! but, OEM reliable...? no, sorry....

So ur sayin my stock engine can handle a kit without work. To the engine?

I have a S38 B36 with a Dinan turbo, puts out around 500 reliable HP. It is complete with the exception of the intercooler. It was pulled from a wrecked M5. Speedo showed 20k miles on it (don't know if that was actual) The engine was modified with low compression pistons and the electrical has extra controls all done by Dinan Engineering.
I have done a turbo conversion on a factory NA car...a VW 8 valve. This is about the most basic German engine in production in the last 20 years. Doubling the factory power and making it reliable ran near 10grand. I ended up with about 350whp and NEAR factory reliability. I can't imagine the costs associated with a properly done S38 turbo...needless to say, the Dinan kit would be quite a chunk beyond the 15k upper limit mentioned by OP. I'd look into a good stand alone like MOTEC, 034, or Tec2. Many of the headaches that I encountered with the VW turbo conversion stemmed from attempting to modify the Motronic ECU to deal with boost. Don't waste your time on that...go standalone from the beginning and save your self the trouble. That said, attaining factory like tractability under all conditions will require a fortune in dyno tuning time. Plan to make the car safe and driveable under normal conditions, then program for full boost, and fill in the blanks as your bank accounts allow. This will be a long expensive process, but will be worth it when you're done. You could of course go the Dinan or VS motor route, but plan to triple your budget, at least...good luck and keep us posted.
