370z AT With Stillen S/C And The Upgrades

there were some people having idling issues who didn't install the shroud that came with the kit, it's a metal bracket, although I couldn't find a way to fit this in after installing the frozenboost heat exchanger as there was no room for it, the guys having issues I believe were running the standard kit without the metal bracket in front of the air filters installed.

I agree, the shop that installed my kit left it off and it caused the car lots of issues. After two days at the tuners trying to figure out what was happening we found that part missing. I made one and most of the problems went away so I made a larger one and it got even better. The third and final is much larger than the Stillen one but it cleared up all the little bugs it had at idle or coasting.

So the shroud solves the problem, but it doesn't fit with the Frozenboost heat exchanger that everyone recommends? Not even the thinner one?

How different is the Z kit, I had the large Frozenboost exchanger and the metal shroud for the intakes

Make your own, on mine I used a piece of flat aluminum sheet metal that bent up and behind part of the lower filter and screwed to the metal bumper. The stillen one screws to the bumper and points down and back into the space where the frozen boost is.

This is the Stillen part we are talking about.

If you look close under the bumper you can see the sheet metal we added( only one screw in it at the time).

When installing the larger 3.5" thick heat exchanger, no idea about the smaller one, there is no room to fit the part, I ended up mounting my heat exchanger underneath the crash bar, some people put it further in front, some people further behind. So depends on where you install your core I guess.

the heat exchanger core completely covers on my install where the metal shroud is meant to go, other people who installed the larger unit, reported not installing this part also and no issues with their idle, my idle is completely fine.

just keep it in mind when you do your install, if you have issues with the idle, you might have to fab something up, otherwise if you are going with the frozenboost core, you shouldn't really need to do anything

A lil update had an issue with code P1239 from time to time. This code would of course put the Z into limp mode. Turn off back on and all good for a Day or Three. Code then started to show itself more frequent so after some research narrowed it to the jumper cable for the T/B. Mark from Stillen got me a new one shipped over. Changed out and now code free once again. Z now has 80K miles running and shifting just fine. Below is a lil fun from TX2K15 weekend!

When I installed my Frozenboost, I made a small rectangle box out of that flexible white plastic. My air filters sit in there now.

I did this because the bottom filter would still have air passing through it, even after the core install. Also, I noticed after my Fan was set to full speed all the time. it would pull air through the filter causing the mafs to get a weird reading once in a while.

Key to getting the MAX from this kit is consistent MAF readings. Any positive airflow passing over the air filters will create inconsistent MAF readings with an end result of turbulence making the Z have a sputter affect when accelerating with a result sometimes into limp mode. Since I'm running the upgraded Frozen Boost heat exchanger that is not allowing me to install the "Stillen" factory deflector, I have had the Y pipe re-adjusted a few weeks ago in cutting away some of the metal where the hood latches into place and making a little deflector from an old licences plate. This really helped with more of a consistent MAF reading allowing for a much better Z response. Oh.. And of course my 9lb pulley helps with that response too!

Sick build! I can't believe I haven't seen your car yet! I live in Katy!
