it is gonna be cheaper for all the way around to just save you money on the ls/vtec and instead, turbo the ls, im gonna have a FULL ls head for sale pretty soon, the ls head, or motor is so much cheaper to boost, its ridiculous. You need to search, it better to have a ls that is sleeved and the head is port matched at least and has adjustable cam gears with aft mrkt valvetrane. all of this would be cheaper than an ls/vtec. dont just MAKE a LS/VTEC JUST to be able to say that you have a LS/VTEC. I am missing the point for you to build a ls/vtec if you are gonna boost. show me a good reason for turboing a ls/vtec compared to a ls motor.
