I think you have answered your own question. 370z stock block was not designed to be blown. All components are stressed when aftermarket parts are bolted on. My stock clutch started to fail withing 8 weeks of going forced induction. Clearly longevity of motor will be compromised. If you can live with size of GTR that would be much better investment. Very few people are will to build 370z forced induction car properly. I count myself in that large crowd as I will run stock motor until it blows and they build up motor truly built to handle forced induction.

There is no definite answer to that. 500whp Though seems to be the upper limit. The problem is know one knows if your car was the perfectly spec'd engine/drive train when it left the factory or the one that just barely passed quality control. Same is true for a GT-R it can fail on the track unmodded too just like a modded Z could. Only thing is that the stock GT-R would be a warrenty replacement where as a modded Z would not.

When I go the route of FI I will probably looking at the 450whp area and that's what I am comfortable with. And I will have enough money on hand to replace it if it all goes to ****. The only thing you can do in the end is hope for the best and be prepared for the worst.

7k miles on the TT setup. Drove it to from TX to NC and back with no issues. It's a DD too.

25k boosted miles. went TT after 5k miles of owning the car. Just replaced the stock clutch a few weeks ago. I got a OS Giken clutch from GTM which I highly recommend. No issues so far.

If you plan to track the car, don't do it. You will just end up dealing with headaches one after another. Track driving is different than a couple runs at the street light against Vin Diesel. Buy a real car and call it a day

Wrong!
If you prepare a forced induction car it can easily be tracked, will it require more money? Yes, but it is doable.

Anything is possible with money. The question is, do you want to blow 15K into the car before you even have a chance to put a competitive run in? It's not just spending money on radiators oil coolers and turbos. There are tons of things to consider once you are actually moving fast. Have you thought about what would happen to your clutch? your diff? your power steering? your suspension? your brakes? There are ton of parts to get into before you can track the car reliably. Buy the right car and call it a day. If catching a GTR is your goal, go buy one or find a slower driver you can pass and call it a day. Btw, look at how many heavily modded guys talking about preparing their car for the track, yet no one ever goes out.

The other poster is correct about you will never be satisfied with the mods.

theDreamer

You just listed the point in modding though, building a car to enjoy. I love the idea of just buying a GT-R and passing people, but I prefer the idea of taking this car and doing something unique with it. I get to put on my SC, modify my suspension, currently deciding on my brakes. It is part of the fun.
Yes I could just go buy a car and run it around and enjoy it, but that is not what I want.
Who said you would never be satisfied with the mods? Coop said it never ends, and that is true but that is the fun and enjoyment. Not that we do not get satisfaction, but we look for the next thing.

Also, look at other people on the track with NA setups, reliability is never something you bet on with any car (factory stock or modified). You want to track you will be dumping money in no matter what, how much is up to the owner and what he/she wants to enjoy.

If I am reading this right, your endgame is not performance on the street, but a lesser opportunity to have more authority on track days.

I'd hardly recommend it. You know (probably better than me) how important driving is on a curvy track to better times. (I am ASSuming roundy-round.)

If you want daily authority on the road, in excess, then yes, it's worth the trouble and the cost and the lessened reliability. (Every HP over stock lessens reliablity.) This curve gets steep up around 500whp.

If you want a dead stock GTR, it will beat the pants off of a modded Z. A bit more money, but then you are in the same predicament: I want even more...

It never ends. But we spend money and modify to create something different.

Reliablity is a mandatory speedlimit sign at the intersection of passion and performance. Who's looking?

I would be quite interested to see how a turbo Z with a good set of tires would stack up against a stock GTR. Might need a new diff and coil overs as well

Back on topic. I think a turbo Z could be a reliable track vehicle so long as it has supporting mods and a vast amount of cooling. Upgraded radiator and huge *** oil cooler are def a must.
