NA or SUPERCHARGED

Quicksilvers · 04-12-2018, 08:10 AM

In my experience with my our builds and helping with other Z enthusiasts builds naturally aspirated or forced induction the VQ37HR gets expensive quick. Parts and labor if you are not doing your own work is quite costly. If you do all the required general maintenance on time on your Z these cars will last a long time. If you are looking to have your Z last 10+ years I would recommend you stay naturally aspirated and do a few bolt on modifications and purchase a long extended warranty with your Z. Forced induction reliability depends a lot on many different things. If you want reliability/dependability with any forced induction set up hope that the correct fuel and air upgrades were done on the Stillen supercharger kit as well as is there a safe tune done by a reputable tuner with this supercharger set up? How was this Z used since the supercharger install? After 30K the supercharger head unit could need to be sent in to be rebuilt? There are a lot of variables to consider. Track days and track experience is enjoying and fun but it takes a toll on your Z with up keep and maintenance on your Z needing to be done. To meet your whp goals you could do it naturally aspirated and do all the bolt on’s under the sun but you will be very close or right at the cost of a single or twin turbo kit. If you want to keep up or beat the new 6th gen. Ford Mustang GT’s if that is what you are talking about it will require forced induction on your Z as those cars are underrated in terms of making power and it will be easier and more cost effective to go the forced induction route. Remember with forced induction the more you push the envelope the less reliable it will be.

FI is great if you can do your own maintenance and repairs or if you have a lot of disposable income. Going by your questions and comments, I'll guess that neither applies.

Buying an unknown FI installation is just asking for trouble.

So me and a friend of mine (hes very experienced just installed a supercharger on his m3 e92 in his garage) would be the ones working on it. What's the biggest expense I expect??? If labor is all me and him...

Damn. I was under the impression that stillen made a nice little kit esp if it was just the stock kit....

Depends on what supercharger head unit you have? The Stillen tuner supercharger kit is expensive to begin with. Depending on if you want to upgrade the head unit it could be between 1K-2Kish just for a basic rebuild from Vortech on the standard V3. With no upgrades to the Stillen supercharger kit and not properly tuning this set up by a reputable tuner you will be running on barrowed time and opening up Pandora’s box. Unless you have the extra coin set aside to replace or rebuild your engine you should not have a supercharged Z to begin with. You should start off with a stock clean naturally aspirated Z and go from there. Definitely search this wonderful forum here and take the time to read about your Z. Good luck.

Uhhh..You can buy a brand new V3 for just over 2K. They do not charge anywhere near that much. The basic rebuild from 928 is $400 and the premium, which upgrades to ABEC 9 ceramic bearings is $700. Thats a far cry from 1000 to 2000. Lets not just start tossing around numbers and misinform people on the forum.

Its 600 xD
I just purchased the V3 SC/SCi premium rebuilt package thay included all seals and bearings. Total was $599.
Then I purchased the impeller because I forgot the package did not include the impeller, which cost an extra $576 with $22 shipping -- totalling to $598!

Total was $1197!

If you trust those vendors to do your supercharger rebuild go for it. I had two people send there Vortech supercharger head units back to Vortech as that is how did the rebuilds on two of my friends Vortech head units for $1550 and $1750 as Vortech is how they trusted doing their head unit rebuild. You can choice how ever you want to do your supercharger head unit rebuild. I would be more worried about how long the rebuild lasts than just trying to save a buck.
