how much is too much

Z370Z011 · 03-23-2013, 09:42 PM

considering going F.I. in the future, but since my Z is my daily driver, the mileage can stack up quickly.
so my question is, how many driven miles is considered "too much" to go turbo? at what point will i have to consider rebuilding the motor due to reliability being a greater issue.. Considering the motor hasn't been abused.

im currently at 26k, maybe this thread can help others as well.

I think the motor will probably take 450WHP reliably for a LONG time (assuming you get a larger radiator and much larger oil cooler
Transmission has it's own issues

very good point on the transmission, completely overlooked it.
i think ive seen people run 2 oil coolers on the motor? is that possible/necessary?

I think for any FI, lets say up to 550WHP, or a stage 1, a 34row is a necessity,
I'd personally run 2... I've already got a 25, and I'd add another 25.

I know a lot of people who run 25 rows with a FI kit and overheat their oil QUICK... Or the car starts pulling so much timing at 220 that it takes away from the point of going FI
(Ahem, Stillen, being cheapskates for only providing a 25)

*not an expert.

But I think also engine longevity can depend on amount of boost you're pushing.

From what Ive been told from sam at gtm that the 370z motors will hold around 550whp with a good tune and a big oil cooler is a must have.. I went with the gtm 34 row oil cooler myself...

nice! i think i might end up running 2 oil coolers lol

550WHP seems a bit high...
As a DD I'd go for around 450WHP

The motor can probably last as long as you want it really until you start pushing 550 or heavy driving (track abuse).
A solid tune with appropriate supporting mods will help greatly in making sure the engine lasts. I am at 400whp with 30k miles on my engine with the GTM stage 1 SC.

My advice would be not to turbo your daily driver.

There's a good possibility everything will be fine, but it's unwise to have your only car be a boosted vehicle you drive a lot.

IMO, first investment is a backup car. 98% of the time going FI gets you something reliable, but it's better to be prepared.

If you browse the classifieds here, you'll see a lot of boosted cars being sold, many by folks that didn't fully understand what they were getting themselves into.

In short--mileage isn't a problem, but the Z should not be your only car if you are going FI, unless you have great friends that will drive you around.

I'm a few hundred shy of 50k miles (TT'd at 22k miles), and my engine doesn't pushing 450 whp as often. For daily driving, it still doesn't see more than 5 PSI unless I'm at full throttle. I'd still like to be tuned to 500 whp though.

so is your Z a daily driver?

Thank you for that very informative response, I never really thought about it like that. So you mean that incase it breaks down right? or its just flat out a bad idea to use it for daily use? I have access to another vehicle, my dad has an 08 F-150 with 10k miles, which i put the majority of them when i went up to seattle. idk why he doesnt drive that thing

lol. But if incase my Z
ever breaks down, i guess i can always go borrow his truck.

however if its just flat out a bad idea to drive a boosted Z on a daily basis, then ill just buy me another car

elperuano · 03-25-2013, 02:34 PM

He means that you should always have a back-up just in case.
Remember you're gonna boost a natural NA car. Anytime u do this to ANY car you always have to leave yourself room to wiggle. You're adding almost 200+ hp to the motor and granted you should not cut any corners sometimes things will happen. Always best to have a back up jus in case something happens.

That being said my stage 2 TT g37 is pushin 540hp/500tq and I daily drive her and even more on weekends. Always sees full boost everytime I turn the car on. About 8k miles boosted so far, driven hard and no problems whatsoever *knocks on wood*
I also have a back up car, just in case.

Nothing wrong with it, just useful to have another way to get where you are going. Besides the risk of catastrophic issues, heavily modified cars tend to wind up with little niggly issues like loose fittings and such that you might not have time to fix before you need your car again.
