Once you modify the kit past what we have designed we will not warranty or support it because we have not tested/approved what someone might do with the kit. At that point we cannot warranty an issue that could have been caused by a modification. Think like upgraded heat exchangers, Blow Off Valves, Couplers, etc won't affect a warranty because they don't mechanically effect the kit in a stressful way. Upping the boost, custom tunes, different MAF's, altering the intake piping, etc are all things that the kit was not originally designed for. Even if it works, we have to tested it to the point where we recommend it, so we do not support it. Hope that helps.

The stillen kit will eat up rings quick on higher boost

The kit design is very poor, Your motor never really gets the proper IAT temp readings.
They're using a pull through maf system, which our mafs are designed for push through
the heat soak is unreal, But expected on a Air/water setup.

We're working on the Air/air right now, with a Cog setup and impeller, 3" intake pipe before blower, 320 pump, 850cc injectors, it should hit the 500whp mark, and be able to maintain it.

Awesome so when you need an idler pulley because you bought a used kit Stillen wont support you with out the hassle of a waver and money order so they can't be held liable for your missing part for the previous owner..

Great F_ _ _ ing way to support the car community. Your business model rocks, good luck with that !!!!

:shakes head:

When I originally started thinking FI. I called Stillen and GTM to discuss their kits options. The technical guy I talked to at Stillen told me they highly recommended me getting a professional dyno tune since all cars were different and that was the only way to get the most out of their kit. Funny to hear a couple years later that following their recommendation would have void their warranty.

The kit work very well if it's used the way it was intended, I have close to 20,000 hard miles on mine. If you go buy a new Z and do a LS swap Nissan isn't going to cover it, how is this any different? What product can you buy and alter that the manufacturer will still cover?

I think the point made earlier was that the kit required modification in order to run properly, which in turn voided the warranty.

It was always that way :/ When I bought my kit 3 years ago they REFUSED me to get a custom tune even if they picked the tuner :/..

They have said they have made changes to their tunes since then but at that time the SC kit and tune made a WHOPPING 342 WHP :ugh2: I whole 42 more WHP than my bolt ons and for only $9600 :confused:

I don't think you understand what I was saying. I was simply speaking about new kits and why we don't warranty custom work.

We are more than happy to support the community when used kits are purchased. In my time here we have never required money orders or wire transfers for these parts. We asked for pictures of the kits so we know what they need and what you actually have (which people who haven't actually purchased used kits get upset about). We actually advise we go over the parts when a used kit is purchased because there are usually a lot of parts that are missing. Yes, it takes time and we can't give you a quote in 3 minutes for these requests, but we really do try to help.

Also, a lot of these comments and experiences are from years ago. Things do change and we are trying to support the community and provide people with a safe and reliable modding experience.

Mr. Team Stillen,
I am sorry for my ranting in the prior post. I shouldn't have acted that way. It's not you that i was dealing with in California.

It was a very frustrating time trying to get the kit running and walking into walls that took weeks to get through. Stillen cost me a lot of extra money with there BS as my car is a daily driver.

The kit is a very well engineered kit and does exactly what it is supposed to. It's guy's like us that wanted more out of it that have issues. It is nice to see Stillen back on the forum as they were absent for the last 3 years.

So it looks like we are headed in a good direction with new blood to support a company that hasn't gone bankrupt. I will say after i filed a Better Business Bureau complaint I finally got service but still was hassled with money order and a second waiver for the idler pulley spacer. If that is not the case now, then you guy's are good to go.

Hopefully change is coming !!!! :tiphat:

Which specific sized frozenboost heta exchanger are people using and doe sit fit without modification?

Also, will my 25 row oil cooler be enough or do I probably need a 34 row?

This is the one most people are using including me but if you have a oil and trans cooler it is going to be hard to fit it in the stock bumper.


Air to Water Heat Exchanger

Hard as in things will need to be modified or just a tricky game of Tetris?

Also how hard is it to change the pulley once the kit is installed?

The hear exchanger isn't that hard the crash bar you'll have to reinstall upside down, LOL,

If you like driving the car leave the pulley alone. Anything over 9 PSI, people have had issue, Lost motors. :/.

most of it has to do with the MAF locations on the kit, theres info on here and I'm one of the unlucky ones who lost their motor. :icon14:

You'll have to cut quite a lot off the back of the standard front bar to make it fit.

to fit also need to flip the crashbar upside down unless you want to cut the tow hook off (even flipping upside down makes the tow hook unusable).

Stillen supercharger long term reports
 

We cut the tow hook off mine and left the plate to bolt a tow strap to. I stuck the strap up in the bumper and stuck a zip tie around it so I can pull it out if needed.

If you track the car at all you also have to worry about stacking all these coolers I front of the radiator because of all the heat transferring to the radiator. If you don't do any tracking/real hard driving it probably will not be a problem.
