Well unless you don't like going fast, I would think the positives outweigh the negatives. :dontknow:

Don't forget Issa, he had a JWT. I think he sold it on my350z finally.

could have been easily searched..
but there are multiple turbo'd FXs

Here is a sticky thread that could have been easily read.

Engine will not deteriorate faster... there is added stress on the seals, the pistons and the rods. There's cases of 90,000 miles twin turbo'd on the stock block (Vinny Ten Racing brags about them all the time) but this is at conservative power levels. I haven't heard of many over 400 rwhp on the stock block lasting nearly as long.
So because of this stress to the engine people go Revup? Or that's a different thing?
Different motor. Because of this stress people go built. They get forged internals such as Eagle H-beam rods and Arias Extreme Duty pistons with a lower compression ratio, along with some valve and valve spring upgrades. For even more serious power they sometimes sleeve the cylinders.
Wow bro.. I kind of see the picture of this.. But what about the engine block.. I mean you are pretty much exchanging the internal parts of the engine.. But doesn't the engine block suffer from the same stress too? I'm just trying to separate fact from fiction in my head.. Thanks Frank!

The stock internals are good to around 400 rwhp. However, the tranny is the weak link and will probably need to be upgraded if you go with forced induction. Get a valve body kit and tranny fluid cooler at least. This is what happens with the G35s.
The stock block is just fine... the cylinder walls are strong enough. The weak points are the pistons and rods. The transmission is pretty robust as is, but you would definitely contribute to the longevity by upgrading the vb and tc.
There's also way too much of a delay in shifting in stock form. Once you've added forced induction of any kind, the tranny can't keep up with the motor. You'll shift at like 6k in order to make it in time before bouncing off the rev limiter. In fully automatic mode, the transmission will NOT shift before hitting the rev limiter if you just plain floor it.

IMO In order to take advantage of the power a turbo set up can generate, upgrading the engine internals is a must. Also, once you go turbo the OEM ECU won't be able to handle the massively changed system. Fuel delivery upgrades (pump, rail & injectors) would also help take advantage of what the turbo has to offer. Finally, you'll need a tune to take advantage of the exact modifications you have made. The purpose of the tune will be to set protection limits for the engine so that it's not possible to get too close to the physical limits of the weakest link in the drivetrain. A good tune can lower the chances you'll blow the engine, or lower the chances for premature wear. If you look into turbo kits, aftermarket engine management, fuel delivery and parts for upgrading the engine (plus all installation costs), I would guess you are going to need somewhere in the neighborhood of $15,000.00. There's a lot of other systems impacted by installing high capacity forced induction.
This is really the reason to do the turbo or not - if the cost is worth it to you. This is not an investment you can count on getting back even if you sell the car. If you can afford it and it's what you want (and your wife won't kill you) then do it up, bro!!!
My plan is still for a turbo kit, but now I'm thinking it's still going to be a while longer. That way I can take a look at every single system to make sure I'm not missing anything.
