I bought my SER about 5 years ago. I started with some upgrades, heeders, intake, clutch, shortshifter,exhaust, brake upgrade and it runs strong. I just need more power. I am looking into a possible swap for a sr20det or adding a turbo kit to the existing sr20 which has about 185,000 miles. I need some help? Can anyone give me any suggestions on what would be best? Thanks.
