SC dont have instant power. Power ramps as the rpms go up. It doesnt have near the "push you back in your seat" like a turbo does. Mine SC will push you back in your seat at like 5k rpms, below that, its just hard accel. My buddies turbo porsche with less hp, just scares me Spooled turbos have instant power, and teh smaller turbos used on the bolt on kits dont have much lag if any. Just look at the torque curves.

One reason why I dumped my Vortech was because of low trq.

On a freeway the SC isn't that bad since they are in their power band. I raced an ATI 350Z on a freeway and he was a little bit ahead of me. We pretty much have the same WHP but my added weight killed me (big 19's and body kit).

i love my coupe and I'd love to go FI with it. California law keeps me from throwing a turbo or 2 in it. Between the superchargers, stillen is good low end but ugly, HKS SC is medium and quiet and Vortech is high end for power building (sorry if my terms suck or if I'm off. I'm generalizing).

Secondly, if I'm not mistaken and I've read people's posts right, if you HAVE gone with the Vortech Complete or Stillen Stage 2 (for limited warranty or state compliance reasons) none of them are really worth the money for the power you gain and most begin upgrading their systems for more HP as soon as they can. Also, once the system is setup, we are told to expect more headaches on top of the usual worries (compression rods, synchros for manuals, tire wear, oil consumption, creaks and rattles that shouldnt happen on a "luxury" sport car).

Thirdly, by the time you've installed your S/C (if you didnt skimp and did it right), you've added $16k (guess-timate from earlier in the thread) to what seems an already obscenely fast depriciating car.

I cant say I've looked at too many other cars since I got my G. Now I'm thinking the safest way to go would be to just get something thats stock and more powerful, say a 2005 M3 or such. I dunno, I'm just thinkin out loud I guess

Yeah I would go FI if it's a daily driver It's better if you have a alternative daily driver car though. After getting my Procharger Installed I gun it like crazy, I have went over 5000rpm almost everyday or every other day for a whole week until it started leaking tranny oil and now its back in the shop, grrrr

perhaps you need larger injectors?

What is that has to do with all his problem?

This really sounds like a tunner issue. which I personally had very bad experience when it came down to my turbo M3 (which is now a race car) do to the mods I had done to it.

I hate the fact that every shop in the area says they got the best tuners. Or one shop can out do the other. I knoe str8 up its easy to slap a FI on any car but with the wrong shop doing the work.. It’s a wrap...

I spend a lot of time researching alot of shops in my area and customers who's car have been completed. Then after I gather my parts I should have a good idea of how im gonna invest my funds into this daily driver project.

I wasted my time with an APS st kit for awhile. Then I decided to do it right and go all out. I didnt buy used parts( except for the smoking deal on a authentic TS bumper ) and went to a reputable, but a little pricey, tuner. I only drive my car on dry days with no rain in sight and everytime i go out in it, it makes me smile. the car was built to be well rounded and not racey, and i think i suceeded in that. if i were to do it again, would i? heck yeah!!!!! even though i am close to buying a gt-r(including parts, labor and the car), 3 years ago there was no gt-r. i bought this car new and intend to keep it and add to the collection one day. and even if i did buy a vette or gt-r, i would still end up adding performance stuff to it. it's my nature .

I had a Stillen SC stage 2,3,4, went to a Greddy TT and am now building my motor. I think when paired with the right parts the Greddy kit is awesome and would make 99% of VQ owners more than happy.

Is your block being built at the moment or are u in the process? 2nd question how dose the Greddy hold up on the stock engine? Any problems?

I hope you still don't go there then...

You hit it right on the head -- I had an APS ST and it was on the flat bed or in my mechanics garage more than under my butt.

Instead of spending $20K to $30K on an FI kit; got with an OEM twin turbo'd car out of the box; I did and am loving it. (I also hope to be one of the first GTR owners in Cali).
