Intake, 3" exhaust, 3" downpipe and turbo elbow along with a boost controller will put you right around the 300 mark maybe 10 or 15 more. Crank hp, not rwhp.

You need to replace the exhaust, especially the cat on the downpipe. If you don't I will heat up your engine bay more then I'd be comfortable with. Replacing the intake and exhaust will net you 8 or 9 psi without a boost controller. This will put you around 300 crank hp, 12psi on the stock exhaust will probably net you around the same, maybe less. I could be wrong, but I wouldn't chance it if I were you.
How's your headgasket? Exhaust- $200-$500 Intake- ebay $40, a real one $100-$130 Downpipe w/ elbow $250 -$400 Downpipe w/o elbow $100-$200 $1000 should get you there, manual boost contollers are cheap too. Make sure you get an aftermarket boost gauge so you can moniter your boost level, the stock gauge reads to 8psi and is slow to react.

The wastegate controls boost on a turbocharged car. There is no boost controller stock.
Like kwnate said, theres no use increasing boost without increasing airflow. You install an aftermarket boost controller inline with the vacuum line going to the wastegate. I would install a mechanical boost gauge. 100% accurate and reliable. Electric boost gauges suck. Last edited by IHateHacks; 07-12-2006 at 12:07 PM. |
