Can it handle it??

I will not be staying out of this

This seems to be getting a bit out of hand here, injectors can fail, lets just make that clear, it's not common but it can happen. I was not implying anyone should have known this was an issue on weiboys car. Just wanted to clarify that weiboy did have a faulty/failing injector.

Stillen uses deatchwerk 600cc injectors which are modified Densos. FWIW, deatchwerks has been around a long time doing this, lot's of 240 guys including myself ran his injectors when they first came out. GTM used to use DW injectors too if im not mistaken, but no longer do. Perhaps Sam could comment on why? Maybe they did not like the DW/Densos or had some fail? I hear the latency on these injectors can make it finicky to tune.

I was also recently told to "stay away from deatchwerks" because of this specific incident, but that was immediately followed up with a story of a bosch injector destroying a brand new race motor. What I took away from it was, sometimes injectors fail. I don't think there is any cause for alarm regarding the deatchwerk injectors that stillen uses.

Weiboys car had knock, the injectors were sold with the stillen kit, the new owner had them tested after running them for a bit, and running into a problem of his own. It was then determined that the injector failed the flow test. Is it really hard to believe that the injector was faulty or failing and causing at least SOME of his issues?

You did say that you examined the car for 20 hours and were unable to fix his issues, so clearly tuning alone was not the problem, correct?

The 20 hours we spent on the car was for us to make sure that the vehicle did not have any mechanical issues as Eric was told by Stillen that his car was faulty in some way. We spent the time so we wouldn't put Eric in another bad situation since he had already bought a supercharger kit and was about to buy another one. We wanted to make sure that he would have a perfect running car at the end of the day.

I know you are a proud owner of a Stillen Supercharger and I'm happy for you. However, you are right, it wasn't simply a tuning problem. It was a combination of a design issue as well as a tuning issue. I think we should stop here, because I think I've said more than I should have. By continuing this conversation, it's only going to get ugly. I think there's a lot of information on both kits and anybody can do the research and come to their own conclusion.

I am sorry you don't agree with the conclusion I drew about the faulty injector being related to weiboys issues, but I still don't think it far fetched and if people are going to use that thread you posted as anti-stillen ammo, they should have all the facts. I am sure you did lots of testing, but that doesn't mean you can rule it out 100% and it would sure be a huge coincidence if the injector had nothing to do with it.

I would actually love to hear what you have to say about the kit, and don't see why anything would "get ugly". Despite what you might think (basing it off your bolded comment) I am not some sort of blind stillen zealot. If there is some design flaw in the kit that was causing detonation why should it not be discussed openly? I have my own theories of possible issues regarding IAT's due to the placement of the IC, but I don't know for sure.

I wasn't bashing you, I meant that I'm really happy that you're happy with your kit.

It is not really my place to come in here and tear apart another company's product.

let me know if i have summarize this accurately enough...

from reading all the post, it seems that

the original owner of the stillen SC kit was not happy and decided to move on to GTM...

the car was brought to sam for inspection to assure there are no issues with the engine.. spent 20 hrs on it... as a result, sam opined that the tune was not ideal, which resulted to the numbers and issues the car is producing with the stillen kit... well ofcourse he also has opinions on the design of the kit as well...

the kit was uninstalled, shipped to a buyer, and installed by the new buyer/owner along with a whole mess of new/cool/smart enhancement to the kit... he then was having problems with one of the injectors and sent to the manufacturer for inspection (obviously stillen's supplier)... that injector turned out to be faulty... somebody then mentioned that the issue with stillen's kit and its tune from one of the cars that use to have it, is only because of that single faulty injector that came with the kit...

...sam then indicates that there weren't any specific misfire codes that the ECU produced related to a faulty injector and that the sparkplugs looks normal...

he is now being called a liar...

my thoughts:
-is sam really happy for the stillen kit owners and did he really spent that much time assessing that kit he replaced?
-i wonder if sam did try tuning the stillen kit and turned up more power than his?
-wasn't there other cars having the same issues with the tune as the original owner of the car with the kit?
-Did any of those other cars have issues with the tune showing misfire codes, messed up sparkplugs, and what not?
-how many times did stillen redo the tune? version 7 for CARB cert?
-could the injector been damaged through all the handling it went through?
-am having fun derailing this thread even more and is somebody going to care?
-is stillen still on the forum discussing their SC kit?
-what happened to greddy turbo kits?
-why would someone who has GTM product bash on the guy who designed his turbo kit? isn't that like calling ur sibling an SOB?
-why is there so much west coast east coast rivalry in the forum... not necesarily accurate but yeah...

sorry too much coffee in the morning... and was bored..

Kirkster

yes
maybe
maybe
no clue
lots
maybe
we care a lot
not that I have seen
greddy?
he wants slow response time from sam
Cuz Mid-A Kicks A$$
Coffee Good

Mr.Squeeze

You pretty much some it up except Nismo's response as well as mine was because Sam said this.

Making the statement that the car had a bad injector and that is why the car was detonating is such a blanket statement and is inaccurate. We spent 20 hrs diagnosing this particular car and logging all the ECU parameters via Cipher and Nissan's ConsultIII Factory Diagnostic Tool. At no point was there any indication of one bad injector. If you have a bad injector on one of the banks of the engine, your correction factor will be different since one wideband on a particular bank will read richer or leaner. Eric's car did not have that symptom.

This might have been the case when he tested Eric's car but was not the case in mine. If Sam wants to say making a statement that a car has a bad injetor is a blanket statement. I could then say the same about is test results that was posted. We can go back and forth all day in the end this was not the topic of this thread but it ended up that way.

Do we have to discuss about GTM vs Stillen SC in every freaking forced induction thread??

cant we just move on and forget the past? stillen sold a bad injector.. they had a lesson and they learned from it..

I dont even know why you people are bashing stillen's SC kit while you dont "even" own that kit..

weiboy718

because it's the forum.....

prescott3656

I can understand how a bad injector could cause all kinds of problems with any kit, but i don't understand why no one caught on to it. Stillen checked the car a number of times and GTM spent several hours on it as well.

As for the op, i would just PM MrSqueez or Dal1307, as they both have Stillen kits and seem happy with them. MrSqueez's kit required some customization but it seemed to be very worthwhile as he had nice results. If it is done right you shouldnt have to worry about excess repairs, however anything could happen and that's why they say, you gotta pay to play.
