M44/M42 ITB/Multi Throttle

[kingpersia]

Hey guys im new to the forums and really join up to get your opinion on stuff because you guys are pretty much the market.
Within the next 10 months i plan to design and fabricate a Multi-Throttle intake system with a carbon fiber intake phlenum for the m44/m42, which will pretty much bolt on. Ive done my research and can see that the price for one atm is about $AU3600. I plan on selling the ones i make between $AU2000 & $AU2800 ( depending on if a carbon fiber phlenum is ordered)
My question is do u guys think that it is worth fabricating it, because im going to be building one for my engine weather or not i sell more (im planning on building something on the lines of the S42).
