That is a big problem with people just trying to put an LSVTEC together without any research. They install a VTEC head on a stock LS bottom and then they get pissed when it fails. They go tell all their friends that the LSVTEC sucks.
Please quit spreading this bullshit. 99.9% of the LSVTEC "horror" stories that are told are the result of someone causing their engine to fail and they just can't admit that their own stupidity lead to the death of the build.
Yes it will be more complex than an LS/T, and more expensive than a GSR/T if he does have the LS block already. But it can be done and is not more difficult than a GSR/T once you get the LSVTEC running.
