As per Chuck33079's comments above, FI (plus necessary supporting mods) is not for the average DD - they can be difficult to drive in traffic and can be expensive to install and maintain (especially if you are paying someone to do the work).

While the VQ is a fairly sturdy engine, there are a lot of "little" things that need to be taken care of before pushing it to FI output levels. Eg, oil pumps have a tendency to come apart at high RPM, stock cooling capacity is marginal (even with no engine mods), &c. Do your homework (Chuck33079's links above are a great place to start), make sure everything is installed properly, and you should be OK with anything below the 450HP max that has been mentioned.

But, if you think FI is for you, go for it. Several other site members seem to be very happy with their setups.

Edit: Looks like Chuck33079 already covered most of this while I was busy typing. He seems to give more detailed answers than I do, so I'm going to take a nap.

A lotta truth in there. FI is a whole lot of fun, but it's a huge expensive project. And you need to be able to diy a lot of stuff, even if you don't install the kit yourself. Maintenance is key.

Also, you need to have a handle of what is going on mechanically. Understand what is going on with the car and the kit. Know why things happen. It's not something where you give a car to a shop, pick it up later and never think about it again. Boosting a factory NA car is not an undergraduate level class.

Start with this: Maximum Boost: Designing, Testing and Installing Turbocharger Systems (Engineering and Performance): Corky Bell: 9780837601601: Amazon.com: Books

The more homework you do up front, the fewer tears you'll have later.

So much for taking a nap. The older I get, the more I hate telephones.

Just because you can go to 450HP doesn't mean you have to. A system with less boost will be more reliable, cheaper, and more "streetable" (eg, a more street-friendly clutch can be used). How many ponies do you really need in a hot-rod grocery-getter?

I wouldn't be at all surprised if a few intake/exhaust mods, plus a tune, wouldn't put a s**t-eating grin on your face without a lot of the expense, headaches, and reliability issues of FI. YMMV

Amen! No matter what mods you make, somebody on this site has probably already done it. Learn from their mistakes.

This. The $15-20k you would save by going with a bolt-ons/tune setup would pay for a lot of track time.

Honestly I think thats the route I am going. I was reading and the cost is way too much. I'd have to be patient for a year to be comfortable to where I wouldn't worry about it. I'm prolly just gonna do manifold, headers HFC's LSD and final drive. I have stillen gen 3 intakes installed already. I want to save that big money for the new supra or GTR. Putting that amount in the Z would put it in that range anways...The Z is just an amazing car and I love it but dying to add my own touches as well as increase performance but again its not a need unless I get track serious

That's what I am trying to do. I'm gonna save my money for the new supra or GTR. I honestly dont need the power. especially that much for my use. again medium track use. I'll look into FI when I know more about it. These questions are getting out of hand lol...For now i'll do manifold, headers, HFC's, LSD and final drive along with tune. I got gen 3 intakes and agency power exhaust on there. with the rest I Should be happy.
