Would you go back to n/a?

[Draco-REX]

Did I love the car before going FI (Innovate stage 2, E85)? Yes.

Do I love the car now? Yes.

Would I want to go back because it takes a bit more attention? No.

What would I change? The lightweight flywheel. I love the quick revs, but the gear rattle and tendency to stall out if I'm not careful gets annoying.

Negative ghostrider. No way I could ever go back to stock. I want to go the other way and keep adding performance mods.

Thanks OP. This is a great post. Im jealous of all of you that have gone FI but unfortunately I do not know enough to continuously check the car for issues and more over fixing any if there are. I think based on the feedback here and others, the best thing for me, would be to keep it NA and enjoy it for what it is. Still jealous of you all and love all the information and videos.

I'm going back NA, may not be permanent but the idea of a UEL header and a 4.56 final drive sound awesome. I really bought the car because it was NA I just got distracted by boost.

I don't think, it has to anything with different placement of the same supercharger, you guys were able to melt stock cats in a completely stock car so..

to the OP, read below:

I wanted to share two videos so that you can see the effects of the Supercharger, Coilovers and other mods..Later, I was able to improve my lap time by another second which you can see in my Youtube page..

In the first video you'll see how the stock car lacks the power when compared to a GT3 and in the second video how I can keep up with the same GT3 even after I took off a few seconds behind him(coincidentally same car and driver, in the same group, right in front of me), of course I am not implying a FI BRZ with supporting mods is faster than a GT3 (possibly a driver error) but it's a good way to see the effects of the mods, since same cars and drivers, in a relatively controlled environment

I believe the reason cats fail has more to do with the tune than whether it is boosted or not.

If you really want to ditch the SC, keep in mind that removing your F.I. doesn't mean you have to go back fully to stock. You could go back to N.A. and run a catless header + e85 + tune. That'll get you 200 WHP with no torque dip. The car feels fun and balanced that way too.

Thanks for all the awesome responses! At the moment I'm going to stick it out and see where it goes. Lots of different and eye opening perspectives in this post!

I would think the same if I didn't see them failing in stock cars,
for the record I didn't have cat failure in my car but I've noticed a crack on the OEM header which is close to the cats on the header, and figured the very restrictive OEM cats might be the root cause..

I think due to restrictive emission rules/regulations many new engines nowadays some with additional cats ..GM and LS motors for instance, they used to come with 2 cats on the H pipe and now there are additional cats on the exhaust manifold and some guy had cat failure which also caused a catastrophic motor failure.. (Engine sucked in the cat pieces)... additional back pressure and higher EGTs...same can be said for the newer MX-5 engines.. cats on the test pipe (down pipe), however, doesn't cause this since it doesn't sit close enough to the heads..
