FI Car Owners..Your honest opinion please.

Sh0velMan

OEM FI cars don't (generally) have wear issues because they're.. OEM.. FI cars. (This is in reference to your comparisons to your 911 Turbo, and even if you bought a Carrera/S/4S and turboed it, the development for FI is already done by Porsche and huge engineering firms the world over, so it's still not apples to apples)

On the Z, there's not even a FI version available at all, so everything from the mechanicals to the tuning solution (while great) is engineered by entities that aren't multi-billion dollar automakers.

With a 'Stage 1 S/C' you could probably get away with a lot. It's not that much more power.

If that extra power, however, makes you drive it like you stole it... Well, if you drove like that completely stock, you'd have issues eventually, too.



Edit: Full disclosure, I've never personally owned an aftermarket-FI'd car. I've had several OEM turbo cars, including my current daily driver (MS3) and have been around people with aftermarket FI my entire adult life, so I've observed a lot, even if it hasn't been happening to me personally.

I have 17k miles in ~17 months on a GTM Stage 1 SC kit installed by a local shop. Other than several oil leaks and some cooling issues I have not encountered any serious problems.

I am also still in the stock clutch and CSC for now, but I do not launch the car either. Launching the car is hard on the clutch and just results in wheel spin on some expensive rubber. Not worth it IMO. But from a roll, the car is impressive.

I also eventually got a custom tune to eek out a little more power for 419WHP/350WTQ. The tune from Sam is pretty good though.

Here is a post I made a while back that might help. I would just tell you that proper preparation prevents piss poor performance. I am not going to tell you that you will get OEM like reliability with an after market FI setup but for me it has been worth the trade off so far.

aftermarket anything tends to wear out your engine more so then OEM(besides things like CBE or intakes), but if you maintain the car as recommended by aftermarket company and OEM, the modified car should be just as reliable as a stock car
