let me also add that with regards to a VVT system on a forced induction vehicle, you are asking to blow it up, unless it was designed for boost. yes being able to breath better longer is good, BUT, may i add that most advanced VVT engines were designed to be high performance, high compression N/A engines, not boosted engines. this is why so many honda fanatics boost their b16a's and b18c's with just bolt on turbo's and no other work, then crank the boost and blow it up.
basically the battle of the late 80's early 90's in the 4cyl performance engine was low compression turbo engines, like our lovely nissan engines, or high compression VVT engines, like the honda vtech engines. toyota was kinda split down the middle and did both, with several turbo and s/c engines, and then the monster race developed 20 valve silvertop.
in the end, VVT won, because it was cheaper to produce once it hit the production floor as it was simply computer programming more than anything, and was easier to maintain and drive daily. however, Neo VVL kicks the shit outta Vtech.
that's why it's not favourable to boost a VE engine, unless you've done internal work. namely, putting in lower compression con-rods, most favourably from the VET. i can just imagine what a SR16VET N1 would be like...
