Not all are like this, but going into the forced induction car on a N/A vehicle can be a big expense and many underestimate this amount. I have been boosted with a SC since 19k miles and just over 50k miles at the end of the year (and a time of about 2.5 years). I have yet to track my car (ring or 1/4 mile) but I do enjoy the fun street driving, plus the pain of daily driving the car. It is a blast to drive but it is not 100% perfect but I never expected it to be.

It comes down 90% to expectations. A large number of people have never taken on a project of such cost and magnitude before, and it can surprising what you need to invest (both time and money).

That makes a world of difference, and have to outlay cash for those things while dealing with a shady shop makes for a completely different experience.

If I had the dough, in hindsight, a Turbo'd M5 or GTR would have been in my garage. But saying that, I don't have the $$$ and my G37 is a killer sleeper car.
I know I will likely have to replace/rebuild/upgrade the trans at some point in the "near" future.
Not having my own "shop" in my garage means that I have to call my install shop every time my car runs rough or I get some funny noise or error light. This can wear on you.
If you do commit to FI your ride. Estimate 2x to 3x what the shop says for timing. This will save you MASSIVE brain damage from waiting for your project to be complete.
Good luck!!

Thanks for your reply and time to share your experience..

Wow... How do you guys find dealers that give you warranty even though you are boosted

I asked my service advisor who is a cool dude if I boosted my car would I still have warranty? He said honestly you would not as Nissan would say the FI created the additional stress that caused the failure. If any alterations you do to your car can be linked to the breakdown you will be denied

He said this to me in a very sincere manner.

You were the first 1 with the 16g kit right? GTM won't get back to me with a price. Could you message me what I'm lookin at for price ?

Some dealers will play ball, some won't. The dealer installed mine.

If I had to guess why people get rid of FI'd Z's, it would be that they cut corners on the build and/or install, and have nagging little issues that eventually drive them nuts. The guys that have no problems seem to be the ones that bought all the supporting mods, and had it installed by a shop with experience with that particular setup.

As far as reliablity goes, I figured that if the car can handle 500-550whp without a problem, I'd aim for the 450-475whp area and be happy. That's still a lot of power, and the car's my daily driver. I don't feel comfortable running something right up to the ragged edge. Still need to get it on the dyno and see how close to that number I got.

When you say supporting mods, are you referring to oil coolers and (for the 7AT folks) transmission coolers? Are there any other mods needed to safely support a boosted vehicle?

elperuano · 01-10-2013, 11:52 PM

Yes. Supporting mods like oil coolers, gauges to monitor the system, clutch flywheel, csc upgrade, prolly to be on an even safer side u could go meth to keep detonation down even more. For AT guys tranny coolers, VBU upgrade n I believe u have to tune the AT also thru Osiris to help keep from slippage.
All these aid in keeping everything in check and being able to monitor if ur overheating oil or over boosting. People who cut these corners can't really tell and realize only when the motor goes BOOM something was wrong.

blueranger · 01-15-2013, 11:42 PM

Have most boosted 7at's gone through replacement or repairs of the transmission due to its stock limitations?

Great question. Subscribe

Legz · 01-16-2013, 11:44 AM

From the back of my head, wow370 popped 3-4 gears, Shumby and 1 other, both are SC I think, popped 4-5 gears.

GTM has a good FI tranny pdf article somewhere...

How is your Forced Inducted Car holding up, Legz?

I only had FI for 4 months, and car has mostly been parked in the garage in the past 2, so I won't be able to give you a concrete feedback yet. But so far w/ the 19 row cooler and increased fuel pressure, tranny is hold good. One thing I do have to complain about is the 7AT first gear is wayyy too short for FI lol, it only takes like 0.1sec to redline lol, making it hard to shift accurately.

My 7AT has the VB upgrade at 8k miles. It's not a ton of miles, but so far has held up nicely. The VB upgrade made the shifts more solid which will hopefully extend the life of the tranny. That being said, I get the feeling while I drive that a rebuild/upgrade of the tranny may be in the future. Only time will tell...
