Hey Octet !
We're all your friends here ...
Check out the thread started by Mikey1600 "So I just ordered my Stillen SC'r" read it thru to the end.
(Problem with the Stillen kit is that it is not really upgradable to any great extent).
Would be happy to sell you my upgraded and Vortech rebuilt Stillen Vortech V3 with the SI impeller (makes 12 lbs of boost with the 9 lb pulley... less than 200 miles on it ... paid $1795 for the upgrade and installation ... make an offer ... it will work but with the following cautions. PM me if interested.
The upgraded Vortech Impeller is more than enough by itself - but don't do it in conjuction with the 9 lb pulley on a stock motor ... stick with the 8 lb one.
You'll be making between 10~11 lbs of boost.
Even that is pushing it with the stock motor @11:1 CR.
With the 9 lb pulley it will produce too much boost...Ka-Boom.
You will also need to upgrade your fuel system and re-Tune as well.
And then - don't plan on
racing it hard...you might be OK with some spirited bursts of speed enough to satisfy, but you won't be able to push the envelope for any length of time.
Definitely add an A/F/R gauge and an IAT gauge as well.
The Stillen design (combining the MAF's before the SC'r and placing the IC after the TB's) greatly limits reliability once you start to add power and heat.
Be careful my friend ...
