Well, i may be switching over to the APS kit. Here's another question: those w/ the APS (or any FI kit, for that matter), are you running test pipes, Hi-flow cats? And exactly how easy would it be to pass smog when the time arises? Do you just go to a specific person to test, remove everything, etc? As I said, the main reason for Vortech is b/c of the CARB b.s., and as much as possible, I'm trying to avoid unnecessary hassles.

Test pipes here. I have my cats to throw back on when im going to try and pass emissions. Out here though, mainly they just hook up the OBD2 and check for any codes. I have heard some people have gotten through inspection just fine with test pipes/HFC's, but im not sure the details of year of car, kit, where, etc.

I think even with the vortech and the mods you would want to do, you still might fail the sniffer, if your setup flows enough. Only other option really is the Stillen.

I'm located in Southern Cali. I'm sure that when the time comes to pass sniffer, i'll figure out a way to do it. I know I'm not the only one to have to do that. So, I guess it'll be APS in my car this summer. I know that i'll need a wideband A/F guage, boost, oil pressure, and fuel pressure. Other guages I'll need? Turbo timer is something I will need, and a boost controller as well. Other things I should factor in?

EDIT: this will be going into a 6mg 2005 Revup Sedan.

thanks guys, JOHN

As far as gauges I would get a wideband a/f (Innovative is a great one), boost and oil pressure gauges. I have a fuel pressure gauge on my fuel regulator not in the cabin.

You won't need a boost controller as the unichip (stock APS EMS) can control boost. Also the turbos are water cooled so you don't need a turbo timer.

The APS TT is a set it and go kit. You don't need to add anything other than exhaust and test pipes. I would recommend the APS 2.5" exhaust and TP's. APS kits work best with other APS parts.

you could also go with the APS 3" exhaust and 3.5" test pipes which would give you faster spool up time and less back pressure, but it would also be louder. I don't mind a loud exhaust, but I don't think it's a great idea if you live in CA.

sweet deal; i figure about 12K should get me the kit, tuned and installed. As far as built motor, i'm really not sure if i want to build my motor, or s/c my Titan. I can say that the stock rwhp brings a smile to my face (my titan has 260rwhp; i would imagine the G35 is around 240-250), so 380rwhp should be plenty....man oh man i can't wait

I thought the APS 3" exhaust is coupe only? I have a sedan, so i'll probably be using the Borla exhaust. Would hi-flow cats be a smart investment, or should i forgo them completely and go w/ 2.5" test pipes? I want my exhaust to flow as freely as possible, but don't want to draw unecessary attention (read: the fuzz b/c of a loud exhaust)

You're right. I overlooked that.

I would just go with the test pipes over the hf cats and keep your cats for when it's time to do the sniffer test.

I'd also look into doing a custom 2.5" true dual exhaust. The stillen or Borla will get the job done, but they are not the best for FI.

when I got my 3" exhaust they were none available so I had a shop custom make mine with 3" test pipes. I am using HKS TI muffler. The mufflers were $500 for both and the exhaust and test pipes came to $600.

That looks like a nice exhaust.

Thanks.

I am not sure if any 2.5" exhausts are made for the Sedan so if there aren't just find a good muffler shop that mandrel bends and you'll be good to go. If you can find 2.5" exhaust for the Sedan I would just go that route instead of custom.

Having gone the NA w/bolt ons, ST, and now TT, I look back and wish I had just pulled the trigger on it sooner.

Not sure what its like out there on the West Coast, but here 11k for a vortech is more expensive than an ST install, and even some basic Greddy installs. I can't speak to the CARB stuff, as the last time I was in Cali they weren't really enforcing it (but that was like 8-10 years ago).
11K for a Vortech is way toooo high. Kit about $4,500 plus install $900.0 add $500.0 for tune and your good to go..for approx. $6,000.0

380whp will put a smile on your face, but I betcha you go back to retune for more power after a while. Almost everyone does. Best thing you can do is not pick up the crack pipe cause once you do you'll be addicted.

the quote I received for this was for the kit, JWT cams, Dc headers, Stillen exhaust, Crawford Z plenum, oil catch can, install and tune.

I can assure you that I am already addicted. I'm getting my Titan s/c via Stillen, and i didn't like the idea of having a truck w/ more RWHP than my G35, hence this thread.

One last recommendation. Since you are close to GTM I'd take advantage of that and take your car there.. They charge a little more than other shops, but they are worth it. Sam will give you a good install and tune. There are people that drive 8+ hours and even ship there car there because he is so good.

Honestly, I think i'll go to GTM. I haven't heard anything bad about Z Car Garage, but if i'm going to be adding stuff to my car, i'd rather take it to a local shop. Thank goodness I posted in this forum, since not one of my friends knows anyone who works on the VQ. (all my buddies drive Hondas)
