Can it handle it??

I agree. I don't have anything bad to say about GTM, but I don't like when people hate on something they don't have first hand experience with. Stillen has been around for a long time and have a relationship with Nissan/Infiniti with dealers installing their kits...so i wouldn't say their kits are junk. Are there pros/cons of each kit? Yes...but I wouldn't say one or the other is junk.

roughly $7-8k for 282 ft lb torque. Price to power ratio sucks. Junk is not an accurate term, maybe lackluster would be better. The car runs, it is stable, it will pull good numbers on the dyno....but due to the low torque, the low end power is only just slightly more than a stock 370. The GTM kit, however, seems to have better torque numbers from what i read.

I have run my car down 1/4 mile against stock 370's and i only beat them by .3 seconds. Granted, if i were using slicks, i may get a full second faster.

I really hate getting sucked into these stupid arguments, but if you are going to quote facts, lets get them right. The turn key is $6300. lower torque numbers compared to twin turbo, sure, all SC kits make less torque. if you're referring to RCZ's dyno of 390hp/290tq, that was on a very low reading mustang, which he put down 256hp and a bit over 200tq stock. on a dynojet he put down 445hp/335tq in near 100 deg florida heat with the same setup.

comparing different cars/dynos is apples to oranges, my point is the kit obviously makes good power, and is capable of even more (squeeze did 470/360 before maxing out his MAF's).

When I was considering kits, I was on the fence about what setup to go with, i chose the stillen because I got a great deal on it, but I would be equally as happy with a GTM kit. I am not some fanboi, im just being pragmatic here.


what most people don't know about that setup is that one of the injectors that was in use on the stillen kit was bad, later confirmed by deatchwerks that it failed the flow test.

first of all $7-8k is what I spent for the kit and installation. And no, i'm not referring to RCZ's numbers...i'm referring to mine which were 390whp/282tq. And FYI, was the same dyno that RCZ had his tuned. So i say from experience with the Stillen kit, that the torque IS a negative factor with the kit. Even on the dynojet it's only getting 335 lb torque. This kit doesn't get any power unless you are in the high rpm range unlike what i've heard from others that have the gtm where the power comes on in the low end.

ok, $8k installed is different, I thought you were referring to the cost of the kit. your numbers were close to RCZ's then, did you dyno your car stock on that dyno? As for 335tq being low on a dyno jet, compared to what? From what I've seen the GTM stage 1 SC put down similar torque (just look at the dynos GTM provides, +90 tq over stock), and looking at graphs it comes on in the same manner (linear of course). The only time ive seen the SC kits making more torque was with stock cats, which apparently won't last long due to the power/pressure? Looking at the facts I don't see how these kits are not comparable.

unfortunately i don't have a stock dyno. I can only base my statements by the experience i've had with the kit on my car. As far as the torque goes, maybe 282tq (mustang dyno) is all that can be expected from this kit. Either way, the performance i am seeing now was not worth what i spent IMO. Barely pulling away from stock 370's down the 1/4 mile and on some, um, "spirited" highway pulls with other stock 370's was not worth that 8k. And i have videos that show me vs stock z's. But at the end of the day, if i could go back and do it over again, i'd do it differently.

If i had the money i probably would.

don't worry, you're not the only one. i'm sure everybody would had done it differently if we'd all knew what we were doing in the first place. just think this is a good starting lesson.

Mr.Squeeze

The reason for the low torque is the rib set up that stillen uses on the back of the blower and bracket.This causes slight belt slippage ,and the power to come on later in the power band.

Ok I sat back long enough on this. For the last few days I have been rereading that post and yet on this forum I can't find anything about the situation. So I say this, can we get the full story on this situation? I do not know why this would be kept silant because people have been beating the **** out of stillen over this kit. You can't blame them if a injector was ****** up since they didn't manufactor it. Lets go please, I ask the owner to air this story out for the community since it is not fair for stillen to take the blame for something they have not control over.

It's not my place to say, I shouldn't have brought it up but I don't like that thread being used as ammo when their were in fact issues with his injectors. All I can tell you is that Deatchwerks confirmed that one of the injectors from weiboys kit failed the flow test. That is certainly enough to cause knock/det and much worse. Injectors can suddenly fail, its unfortunate but it happens. I just wanted people to keep that in mind when looking at that thread.
