let's see...
WEIGHT
- 97 dx curb weight: 2271 lbs.
- 97 ex curb weight: 2460 lbs.
- 189 lbs. difference.
- btw, 99-00's weigh a bit more than 96-98's.
TURBO D16
- a boosted d16 can make 178 whp 148 ft-lbs @ 7psi (0.46bar)with the edelbrock kit (costs $3,000)
- more could be made at the same psi with proper tuning, fuel management, etc.
- a custom turbo could cost you no more than $1000.
ITR SWAP
- stock JDM b18c5 costs about $4,500 and makes 210hp 134 lb-ft. this is before drivetrain lossess.
- stock USDM b18c5 makes 195hp. not sure of price, but a couple hundred bucks cheaper than the JDM motor.
....
however, what exactly are we comparing... the costs for these choices aren't even remotely close to each other... but whatever. if i were u, i'd boost the SOHC.
