But since I had so many problems I'm not going to put a smaller pulley. I want to but I think more power now is not a good idea. Since is running good now I'm going to leave it alone.

can you elaborate on the fuel line problem?
i am running the fuel pump that came with the kit, did all the mods to the housing and i am not having trouble with fuelling apart from it running a tad lean near redline (which i remedied by lowering the redline from 7500 to 6750)

Are you talking about the line that connects the hardline to the rails?

I have just installed this kit, i am running stock headers, berk HFCs, Motordyne XYZ Pipe and Tanabe Exhaust, so pretty much everything except for headers.
I am seeing 8psi on the dyno and 9psi on the road, so i consider this to be a myth.

Hi niko86, Im curious. Stillen told me the headers would cause a boost loss and lean AFR whereas HFCs would not take the elevated temps.
I still have my Berk HFCs in the box (purchased them recently). I loved the idea of better flow, an extra O2 wideband bung (coz i wanna get an AFR gauge too) and spiced up exhaust note. But now I'm tempted to return them to Z1 Motorsports because of Stillen's advise. I was wondering how your Berks affect your kit. If it's really the temerature stress I guess you wont be able to tell yet since your kit is still faily new. Well, good luck with it i hope they last you long.

sure, metallic catalyic converters will break sooner than ceramic ones, but that's more of a maintenance issue than a performance one i think

I built a couple of turbocharged cars and still do, i have always used metallic HFC type cats, and the only downside is that you will eventually burn out these cats and need to replace them.

if things go really bad you might have excessive back pressure from a deformed metallic cat in your exhaust thats clogging it up.

What i do on my other cars is just checking on the cats whenever i do an oil change, that's easy enough, does not take long at all, if needs be, i just replace them.

Generally with forced induction you want to reduce back pressure, i am not sure what the deal is with the vortech V3 unit, maybe it's not capable of pumping enough air if the back pressure decreases too much.

So basically it is not a problem the HFCs are introducing into the system, but rather the heat will be higher because of the forced induction, which will shorten the live of your HFCs

Thanks, that explains it well.

What radiator are you having in your mind? I was looking at the Mishimoto, 4cm core thickness. I just hope a thicker core fits with the SC kit.

CSF. Mishimoto is awful Chinese garbage.

Friends don't let friends put Mishimoto crap on their cars

V1H · 10-20-2014, 01:45 PM

Always thought Mishimoto is Japanese

Well, I got the Mishimoto Weighted Shift Knob (363 gramms), which I totally love. Even the Nismo stick doesn't touch this. Perhaps my fav mod on my Z

(kidding)

Either way, I will look into the CSF. ;-)
Oh and exactly which larger heat exchanger did you pick? You were saying Frozen Boost. Is it Type 114 or 117? Thanks

That's why they named it that way. They want you to think it's Japanese.

Check your fuel pump assembly to see if the fuel pump is floating or secured like it's supposed to be. Also look to see if the fuel line is cut. Not much more I can elaborate than that.

Diego, did you experience the power loss on HFCs with the Stillen base tune or did u run a custom tune and still lost power over stock cats?

wifedrivenZ · 10-22-2014, 12:27 PM

Why could we not of talked about all the problem that can occur with headers and high flow cats 2 years ago? Well I guess I am ok since I have not had any problems since I have upgraded. I am curious if I change out my cats back to stock would I make more power?

nomodsjk · 10-22-2014, 12:49 PM

I'm getting so sick and tired of the damn tps codes and limp mode! Happened again today and it pisses me off something fierce! I love the stillen kit and have nothing but good experiences with stillen but this has to stop. I've tried just about all the normal suggestions associated with this problem to no avail. Nothing seems to help and when I took it to r/t tuning a couple months back of course the problem wouldn't replicate on the dyno or on their test ride so there was nothing they could do for me

Did you have the MAP range extended?

I'm not exactly sure what you mean but I got a custom tune from r/t tuning so if that's something that a highly reputable tuner would do than I would say yes
