Spyder 2g recommended upgrades

[mkoldus1]

Hello everyone i am a 15 year mercedes tech that just got into a 99 gst spyder 5 speed. This car sat for 3 years with a blown clutch. I installed a new clutch and master cylinder. I did the necessary maintenance items ( car has 130000) so didn't know history did the the timing job, changed oil, coolant, took the pill out of the boost solenoid, swapped the internal Wastegate to a 1g, put in a new air filter kit, also a boost gauge. The car consistently makes 12 lbs of boost and I can tell it runs slightly lean in the upper rpms around 6500. I know ill need injectors but what else would you recommend? My goal out of the car is a really fun daily with max performance goals around 300hp. I know with front wheel dr that's really all the power that can be used. Thanks for the read and I appreciate any posts.

Not too much needed for 300. I’d start with checking to see what fuel pump it has. If it’s stock, upgrade to walbro 255 and rewire it. Guess you have a wideband but if you don’t, you’ll need one. Here’s a good read
