Forced Induction Reliability

spearfish25 · 11-29-2009, 04:22 PM

I've been lurking around the GTM site as well as reading about SC and TT kits by other manufacturers. While everyone claims some level of reliability, what has been your real world experience (those of you who have gone TT or SC)?

I love the idea of eventually getting my car to 500 rwhp which would be a blast on track days. But do these kits really behave reliably, or does making the conversion also buy yourself a future of leaks, problems, parts, and fixes? I'd rather dump $80k in a GT-R than spend $30k more to get my Z to 500 whp with appropriate accessory mods only to have it be a 'shop' car getting fixed rather than a track car being driven.

Thoughts?

In my past experience, when ever you make a car that came from the factory N/A into an F/I set up, it always leads to problems of 1 kind or another. Hell, even cars that come from the factory F/I have issues, coughSTiandcough. Also, even without taking F/I into consideration...the more power you add over stock the more issues will want to pop up, weather it be engine, transmission, diff., ect. related.

Just my 2 cents

as long as it aint your daily driver your fine. your car being down for a week because of some mundain problem cant happen if its your only ride.

thats not to say it CANT be reliable, but sh!t happens. hell the guys from my.is who turbo IS300's have lil things that come up here and there.

Shoot I am DD my soon to be TTZ... and will continue to do so after the TT kit. Granted I have Forged performance right down the road so down time will be minimal... Reliability comes in the quality of the kit and the Tune... and also how well you maintain the vehicle... Seeing as my vehicle will be a trifecta of Track ready/Daily Driven/Show Stopper I have to take good care of this daily driver!

Rob@Altered · 11-30-2009, 03:19 PM

It all depends on how you drive your car. Of course, at first you'll have problems you'll have to iron out, but after that it's mostly up to you...

If you beat the crap out of your car every day, and don't have any supporting mods to help sustain that level of performance and reliability, then you're begging for problems.

If it's a daily driver, and you modify your car appropriately for the power levels you're looking for, then it should hold up if you keep to a good preventative maintenance schedule.

Clint@Altered · 12-01-2009, 09:05 AM

+1 on what Robert said. As time moves forward, people will see that the 370Z is a very reliable platform for F/I.

If you have a good install, proper fuel, proper engine management and monitoring devices, a solid tune, an understanding of how to monitor your vehicle, and follow a maintenance schedule, your TT 370Z should provide long-term reliability.

Even on the much weaker DE motors. We've have customers who've put over 70K miles on their cars with twin turbo kits with no issues to date.

TARDCORE · 12-01-2009, 09:49 AM

whats your professional opinions on turbo vs super charged aftermarket kit's long term reliability? I always figured a supercharger was more of a set it and forget it kit compared to a turbo kit but I also know that if you put alot of money into it any set up can be a DD, you just gotta have the cash.

JB-370z · 12-01-2009, 11:38 AM

Shoot I had a turboed rsx-s and it was a DD and I had no problems(313Hp). But then again I drive like a grandma! : ) I put 62,000 miles on it with the turbo and a total of 88,000 miles. I made sure I wraped everything to sheild from heat (heat kills the life of all components: liquids, plastics, rubbers, metals)! I never had any probs though. Just did regular maint. a little sooner than the avg.
Be able to monitor any changes in your system.
Most important (TUNE)
The most important factor after buying a "trusty" kit is a grade A tune. Then retune after every so many miles every kit is diff! You will spend alot of $ keeping a perfect tune. Its not just tune and go! I did a main tune and then 2 or maybe 3 retunes can't remember, but that was also do to adding in new components. But the type-s was very reliable. But all engines are diff so who knows about the VQ. But if you drive like a idot than most likely this thought goes down the drain.

terrycs · 12-02-2009, 12:43 AM

I'm approaching 20K boosted miles on my HR-TT with no issues. UOA on every oil change is still looking good as well. This is a DD with 20 miles one way to work with speeds ranging from stop and go to "fast"

.

Like the others have said, it's all about how you drive the car.

BTW ... If you take your GT-R to a track, you can kiss your warranty good-bye.

I have a dealer installed Stage 1GTM kit with Setrab M25 oil cooler. The car now runs as good as it looks which I could not say without the SC. The biggest problem I have is that I am hitting 250 deg F. during normal freeway driving in Houston with an outside temp of 98 deg f. A couple of times now the computer has put it in the "limp home" mode.
I think it is because of the mounting position of the oil cooler. It is mounted agains the drivers side wheel liner. Air can't get to it or flow thru it. Once this problem is sorted the next step for this car will be an exhaust system upgrade.
