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.

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.

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.

It's a noble idea except not many people knows what they are doing and they just end up wasting money and time.

Factory cars are almost always more reliable, I am not sure where you are getting the unreliable part from?

Oil temp issue
Fuel starvation
Brake fade

All from a factory car.
Many cars have issues when thrown on the track which cause reliability issues which then require you to mod the car to fix.

cossie1600 · 07-10-2012, 11:31 AM

how many times have you been to the track? you do know all cars will need some basic stuff right?

Not with the SC because mine is not prepped yet.
I still need better brakes, running on the OEM pads (deciding what level I want) and need Nissan to replace my transmission before I start romping around.
That is my point, you were saying just buy a car and call it a day but all cars need prep (minus a handful). NA or FI neither is reliable so you coming in saying if you want to track do not buy FI is just wrong and since you have not provided any info other than agreeing it cost money then thank you. Also, have you boosted a Z and ran it around the track yet?

cossie1600 · 07-10-2012, 11:45 AM

what you mentioned are track necessity and car design flaws. what happens when you go fi? everything magnify and become worse. what are my chances blowing an engine, losing a fitting, blowing a hose than you? much less.

and lets not even get into the prep work on brakes and suspension

The bold part is still required for NA.
Also, you still have the same issues with a NA car, you can easily blow a hose or even your engine. VQ is known for having some engine oil issues or you push it to hard in the heat and your radiator gets dinged with road debris you seize up. FI v. NA is not some huge leaping step if prep is done. With a NA car you are still going to have to prepare and be ready the same with FI. At the end of the day I spent more money though though, that is it, we both still prepare.

Which returns me to your original point:

That is wrong.

Damn... guess I better tell Tony to take my TT kit off after he prototypes it...

Spend some time at the track days and you will see why.

Btw, you are right that you can certainly make it reliable if you are willing to spend tons of money and basically bring a shop with you. But then at that point, is it really worth while to keep the car? Just buy a faster one to start.

I have spent plenty of time at the track, I just have yet to run my boosted Z.
Plenty of friends with 350z who are boosted who run all day without issues, only bringing themselves and some tools. Hate to break it to you, but it is not some magical fairy dust you need to run a boosted Z car at the track. It just takes knowledge and prep (and some money) and you are fine, nothing much more than running a NA Z around all day.

Maybe you should spent sometime at the track with a few boost Z owners and see how they do?
