370z Forced Induction for Noobs...

SDatl404 · 05-13-2015, 09:04 AM

Just curious what everyday hard driving would do to reliability when boosted. Like transmission, rear end, driveshaft, ect. Can you still drive the car hard or is it going to pop something when you turn the boost up?

All depends on power level. The OEM drivetrain seems to be able to handle normal boosted (~500-600whp with proper fuel and tuning) without any major issues. It's likely that, from 'hard' driving, it's the motor that is likely to let go first.

My tuner did blow out a rear diff but it was on an E85 tune with over 600whp and coilover/chamber settings to make it hook-up.

Things can still break as you are talking about boosting a factory NA car, but this platform has shown it likes boost

I have about 5k miles of hard driving on mine with no issues except that my face hurts from smiling so much.

I'm at about that many miles and mine is a garage toy. It only comes out when it's time to play.

Thanks for the info. I want to boost. Nothing crazy maybe 500 rwhp, but I was worried about the car grenading if I wanted to do some spirited driving on a road trip.

Do your research and buy a good kit. Have it installed by a good shop and make sure you have a quality tune. If you do that then it should be reasonably reliable.

But always keep an 'oh shit' fund handy as you boost a NA car and you are always playing with fire.

Boosted cars seem to go boom earlier for people that don't really know what they're getting into. I'm going to guess by your questions, that you have no intentions of DIYing this project and haven't boosted a car before. Don't cut corners with your shop. Be prepared to throw $10K at least into the project and have enough funds set aside for when something does go wrong. Proper maintenance and regular inspection of whatever FI system you choose is extremely important.

Fast Intentions makes some good points in a thread specifically regarding maintenance and longevity of their TT kit. There are a number of other threads (including ones stickied in the FI section) that you should read up on before moving forward.

TT Maintenance and Long term things NOOBS should know

That number is more like $15-20k if you plan to do it correctly.

Install and a quality tune are the most important things when boosting a car that came NA from the factory.

I've got plenty of experience modifying cars, just not 370s which is why I asked for insight from the community. I don't want to boost the car if the driveline is fragile. I love the 370z. Super fun car, but more power is always welcome if it can be done without affecting reliability or forcing me to change the way I drive my car.

There is always the chance that something can go wrong, however a lot of us have had nothing but positive experiences. Stay up on your fluid changes and you should be good to go. My car doesn't leave the garage for anything but "spirited" runs

Do you have experience boosting a NA car? That's probably the key experience you would want.. As mentioned, a number of people are going strong on FI, and those that have had problems are typically due to the tune.

The Z bones are fairly strong. 7AT is pretty much the weak point; 6MT less so but still needs new CSC and clutch to handle FI. Motor is pretty stout to a certain point. A lot of the supporting mods are for cooling purposes. The Z likes to run hot even when NA, so it's important that cooling is a priority when boosting.
