mate a new e-manage blue will run you around $400-450usd. you can find them for half easily used on the forums. if ever you decide to upgrade turbos, you can still use them. many 250-300hp starlet around with the e-manage. a manifold upgrade is a must..porting stock manifold will work but you'd be more susceptible to the stock cast manifold cracking once that's done. a after market manifold is your best bet. good electronic boost controller would be an Apexi avcr. as amjad said..fuel pressure regulator not needed if you have an ecu. 255lph fuel pump upgrade would help..try a walboro drop in pump. sacha
