I've been thinking about forced induction for my G, but the expense and reliability issues with the twin turbo kits worry me. From what I've learned the VG35DE is really not made for forced induction. You can get away with running low boost levels, but the power gains at these levels are just not enough. Is there a race shop or tuner that builds race tuned VG35DE's? It just seems to me that this would be the way to go if you want more power. It may be a little more expensive but there should be less reliability issues. The engines would be running the way they were built to run.
Johnny you can put a Stroker kit in the engine if you are looking at big boost and big hp. Chromium Blue started a thread about this in the performance section. It is pretty expensive, but you can get good power normally aspirated with internal mods to go with higher boost if you want to in the future.
With a supercharger you should be able to get about 360 to the wheels with a little mods. Once you start going down the TT path you are correct that it will start to get very expensive very fast.
For a serious race engine from a good engine builder you are looking at $10,000 to start with bare min... going up from there wiht proper R&D. Our 350Z race engines for the Grand Am Cup series are above that... complete engine mang and a wiring loom you are looking at $7500.
Thats just a complete B&B'd engine with cams.
Yes, but at least you're getting a separate engine for that! You can defray the cost by selling the OEM engine or just keeping it if you decide to sell the car. What the folks doing the turbo or supercharger mods are risking is a total engine replacement if it blows up - buying a crate engine doesn't risk that, unless you sell the original.
Anyone, in my opinion, contemplating spending many thousands of dollars on extensive engine modifications should seriously consider buying a crate engine instead.
