i got a oversized O2 housing called a Zebel housing. it has a divorsed wastegate and a larger opening.






i had some IC hardpipes made and i made them 1.75 inch in size, its the stock size. i deicided to keep them the stock size cause im using the stock turbo and the stock intercooler. i changed to a DSM 1G recirculating valve. it has smoother power and the boost is steady. i also added a Turbosmart MBC.






i dynoed the car the other day at COBB TUNING in Plano TX and here are some numbers.
163 HP to wheels
248 ft/lbs to wheels
14.3 psi
12.2 AFR
the car has about 183 HP at the crank and 280 ft/lbs at the crank. not too bad for a 18 years old car and turbo!!!
