Vortech or STS?
(1) American Racing Headers (1 7/8" primaries) will be installed next Monday.
(2) Selling the AFR 205's and buy new heads to bring down the compression.
(3) Selling the SVO 30# injectors to upgrade to 60#'ers before year's end (in 22 days).
Then it's coming. AIR ASSAULT!!!! 101st Airborne Division (Air Assult) ... keep your head down over there bud.

The Best V8 Stories One Small Block at Time
Anyway since then I have become interested in a p1sc. Anyone know if having a FMIC causes any problems with smog? Technically the E.O. says an air-to-air intercooler is an allowed modification but does that mean it needs to be the one from the ati kit or can it be some other intercooler?
For example:
Procharger - belt slippage. It needs to be stupid tight. The one on my firend Ricky's car is like guitar wire it's so taut, but it still only produces 5PSI on a 7lb pully. Install of a new belt is also a chore, as on an auto trans car it goes over the lines, meaning they have to be disconnected from the radiator. He was also experienceing some cooling issues in Hawaii stop and go traffic and the IAT's were stupid (granted, he does have the OLD intercoolers). Still, we saw intake temps over 150 degrees a lot and over 190 degrees once!
Vortech - Well engineered. Need to drill into the oil pan, which is a scary proposition if you muck it up! The aftercooler is a bit unsightly on top of the engine, but easy enough to get on and off. The biggest drawback of the Vortech is that in the aftercooled kit it has a 9lb pully. That's really streatching the limit of what the engine can handle.
STS - The pipe in front of the driveshaft hangs lo making speedbumps a real pain. TRT sells a kit that lessens the drop, but it's still there. A FMIC is really a must, as IAT's will go over 135 in traffic w/out. Also, the front pipe hangs LOW w/out the FMIC. Not able to use subframes on the driver side either. Also need to buy a lot of the parts separate, as the kit does not come w/ fuel injectors, pump, etc.
In short, do your research and you'll be able to determine what is best for you. All FI kits have their pros and cons. They end out about the same $$ once complete (5-7K total).
Hope this helps ya.
I have had my STS kit for a few years now. I have yet to blow a charge pipe at 13 psi of boost. (190kpa) Which btw has dimples to help hold the hump hose on the pipe.
I am open minded enough to stat the return oil pump (which has not gave me one once of trouble) is noisy. You can just barely hear it over the fuel pump on the driver’s side. I still hate the fact I have to rely on another oil pump that is prone to fail, but so far so good.
I cannot comment on some of the other things said, as my kit is obviously in a truck not a car, and I refuse to **** on a product before I try it myself....
It doesn't matter what type of FI you go with you are shortening the eng life. By how much will depend on many things....
Like said earlier, there is no Vortech rep or sponsor(that I know of) on this forum so that might have something to do with the results of this poll as well.
The upgrades and double-work alone will make the APS system look cheap.
NEG's
1. The oil pump sucks. So does the high-flow upgrade pump.
2. Count on losing boost by the time the air hits the manifold.
3. 11ty-billion extra places for a boost leak
4. Hot-side piping is ***.
5. No ground clearance, and watch the f*ck out when backing up near a curb.
6. Turbo = not a muffler. NO stealth factor AT ALL.
7. Remote turbo: good for cooling intake charge, also good for cooling exhaust...bad for heat-loving turbochargers. Requires exhaust wrapping.
8. Spools in about the same time as it takes a 4cylinder car to pass you.
PLUSes:
1. Initially cheap. (You'll find out why when you bolt it up).
2. Fairly simple install.
3. Sounds terrific if you like to hear the turbo...it's f-in loud.
4. " " " " " the sound of open headers.
5. Oil pump noise gives the car that "racecar" feel.
6. Scares children, small animals, and most would-be challengers at a light.
7. After you upgrade everything in the kit: Mother of Christ they are fast and make good power.
8. Referring to #8 above, that 4cyl car enjoys precisely 1/16th a second of victory before his paint is ripped off the car as your fully spooled turbo passes him like he threw on thrust reversers. This also works with V8's, V10's, etc...
There is nothing left in my kit that even sounds like STS... other then its still a rearmount. You gotta love a turbo under your ***!
What are your no-**** goals?
