***SuperCharge Fit***
I am sure that's totally true for many many people, but I just want to throw some more experiences out there. This is relating to a Miata, and not a Fit, but I think it's still kind of relevant to show that turbo can be smooth sailing, or it can have it's issues.
I have a friend with a 1.8L Miata who put a Flyin' Miata II turbo kit on with ALL the goodies and everything needed to make it run. He couldn't get it tuned well but in the end decided to take it to Flyin' Miata themselves, and they gave it a fantastic tune. He ended up making 260whp @12psi, and it ran fantastically well. A real hoot to drive too as you'd hope. But since then it's gradually started having issues with the tune, and he's really had nothing but trouble. And this is a kit from the most reputable Miata turbo guys, tuned by one of the guys from the same shop that builds the turbos!
I know it's a different application, and a higher power one than a lot of Fits are running, but I think it's good to be aware that turbos are not *always* smooth sailing once they're well tuned. My friend has been pouring money into his car for the last two years to get it running well again, and right now it's running poorly and failing emissions tests.
For sure it can go really well, but be aware it's not guaranteed

Not only is he a single data point, but we don't actually know what his issues are.. unless you feel like elaborating?
You are also talking about a Miata engine not a Fit, and what year? How many miles before he decided to double its power and torque output?
How does he drive it?
What sort of supporting mods was he using to support an additional 12psi fuel pressure and >25lbs/min airflow? I am guessing this is on an otherwise stock engine?
Because it is real easy to blame the tune when you don't know what you are talking about.
Especially one that was "fantastic" to begin with. That indicates other issues because the tune doesn't just magically disappear one day. How long has he had the car? Did he get it tuned and installed in the summer and then have issues in the winter?
Stuff like that is important..
There are many people on here that have been running 10+psi for a long time now through the L15A1 and now there are a few doing the same with the L15A7 with no issues. Some turbo some supercharged. Many in hot climates.
Way to bump a thread from 5 months ago.

I'm sorry I really don't see the problem with that when it's relevant to the topic that was being discussed. Better than starting a new one.
And yes, a friend, not me. I absolutely see what you're saying, but to save spending hours wading through all the details of my friends setup and issues, all I was trying to say is that not all turbo engines will always be easy going all the time, and that's something that might be worth considering if you plan to go turbo.

But thanks for sharing your anecdotal evidence of nothing. Any engine you push, stock or turbo is prone to failure, and often for the same reasons. That is something worth considering with any engine.
You don't have first hand ownership experience or any details to share but you are warning people about going turbo? That is something worth keeping to yourself.
Like the guy you quoted initially, who actually owns a turbo Fit.. with a good tune you only need routine maintenance.

Yeah I see your point. I wasn't trying to be negative about turbos whatsoever, I had the best of intentions with my post. I took his comment as being more about turbos in general not really Fit specific applications, which was my mistake.
Ugh, the problem was that you made such a baseless sweeping generalization in the first place.
Turbos in passenger cars were unreliable in the 70's and early 80's. Just like diesels were.
Unfortunately this stigma still sticks to turbos and diesels because people who don't know any better keep repeating the mantra. There are very few post (OBD1) 1989 turbo vehicles that experienced more problems than the average passenger car because of something directly turbo related.
There is no reason a stock or aftermarket turbo system has to be unreliable. Or any form of boost for that matter.
One important thing many people don't understand is that to double power production you only need to increase cylinder pressure as little as 20% in some cases. That rod angles, of which we have a favorable r/s ratio, play a big role in longevity when you are increasing output.
Turbo's also make engines more efficient. Superchargers do as well, but not to the extent a well matched turbo can. Even the best Rotrex supercharger can't match a modern Borg Warner or Holset turbo which can see as much 80% compressor efficiency.

In this case mostly just being an ass.. because I hate hearing myths, half truths and bad info tossed around so flippantly.
But I will definitely give you credit for manning up and admitting you were wrong which is rare around here without the thread nosediving into three pages of flamewar.. so +Rep for that!
hey guys, quick question.
Are front strut tower bars compatible with your kwsc high boost kit?
After looking at the pictures, i feel like my mugen strut bar will be in the way of the intercooler cowl tube thing.

Well no one else is posting any thing up so I guess I will, its nothing special
this is on a Automatic Fit
Under the Hood
Kraftwerks Supercharger base kit (5psi)
Kraftwerks top mount intercooler
195CC infectors
Denso Iridium Power IK22 Spark Plugs
T1R Header
T1R test pipe
Spoon Sport B-pipe
Spoon Sport N1 axle back
Power = 120whp

i love your fit engine cover. where did you get that painted? it looks sweet!
thanks man, Its hydro imaged. A guy I knew, knew someone that did it so I ended up going through him.
It was a nice looking setup. The 5psi kit for the manual transmission cars felt like there was a larger version of the factory installed engine under the hood and still got about 35 to 37 MPG .... It suffered a very noticeable power loss when the ambient temperature was over 85 degrees....
5psi on a small compressor with stock VE and a small, underhood, top mount intercooler putting the power down through an auto trans...
Thats about ~10whp/psi which is not bad for a small centrifugal compressor with curvilinear boost threshold when you look at VE (which tanks fast after peak torque)
We don't know what conditions were on dyno day either.
Why is 120whp surprising?
