Stillen Rules
My local dealer installed Stillen headers and cat-back exhaust. I paid way too much because the dealer added their mark-up but they told me this was the only way to preserve the warranty. I ended up having problems as the bolt in the steering universal joint was touching the headers in hard right turns. It was a little scary at high speed. They replace the bolt with a flat head and it solved the problem. So much for dealer quality!
The additional power is noticeable, especially at higher rpms. I am very satisfied with my base +sport package 370Z, which cost less than my wife's minivan. |

If you're looking for more boost and power to push a build motor i would suggest going the turbo route. The Stillen kit is great for 400-450whp after that you're gonna hit a brick wall cause there won't be room to grow. Improvements yes/more power unfortunately no. Just my

Oh I hear ya man but I'm not looking to go too crazy with power upgrades since it's pretty gnarly as is. I would just like to get the most reliable power I can out of what I have. I feel like a few internal upgrades, impeller and pulley would be more than enough to keep me happy for years to come..

I would be pretty happy with 425 whp/325 trq. This kit probably needs the 9lb pulley to get there though, bu that also puts me into more iffy trans territory. Has FI come out with pricing for their auto trans upgrade yet?

Level 10 requires shipping the whole trans off, seems like overkill for that marginal power gain (9 lb pulley) It would be more worth ti for the impeller and 9lb pulley combo, but it seems the engine has issues with that. Does anyone know how much the level 10 built tranny is?

I was thinking of doing something like this for the MAF pipe. This still doesn't fix the problem with the location of the MAFS. but might help to get more even MAF readings.
what do you guys think? Sorry for the huge picture, used it off a site.

If you block off any air going directly into the lower filter any issues with the MAFs not being even should go away, it did on mine. It wold be a lot cheaper than doing that.

Its actually not to bad, The pipe, couplers and filter and mounting hardware is $134.55.
plus, it will give me more room under the crash bar to mount the intercooler farther back so I can retain the OEM tow hook.

Hey guys, I'm new to the forums and I'm looking at getting a 2014 370z. The previous owner installed a Stillen SC and has a AEM water/meth kit installed. He has drag tires and the car has 17k miles along with carbon fiber body parts. From what I can tell everything looks to be in like new condition. I started reading everything on FI and Stillen SC. Anything I should know before buying it? After reading parts of this thread I don't wanna buy it and the PSI be to high or water/meth mess up something. I'm new to the car seen and for 30k seems like a steal to me. Anything helps, thanks!!

How much boost is he running? That water/meth kit should keep the intake temps in check which is the downfall of this kit in the first place. However, I personally think they are huge pains in the ***. You always need to worry about filling something up plus its just another complication added into your system. If he is tuned aggressively for meth and it ever runs out or stops working due to mechanical or electrical failure, then it could be devastating for the engine.
