No you dont NEED the msd but it will help. Im still running the stock ignition with a blaster coill and i have no problems with spark. You will need 42lb injectors and if you have a FMU pull it out, you will need to get it tuned and they will sort the fuel issues out there. AS for the TB id go 70mm maybe 75 if you plan on upping the boost/getting bigger heads down the road. And yes its def a respectable driver, you should be putting down around 375RWHP which will most likely take care of 90% of the challenges you will get on the street

You dont "need" a box i just got a coil on my boosted car injectors id go with 42's and lightning maf at least thats what im running on mine but u need to get it tuned with it tb get a 75 but u will need to bore out the intake where it bolts up too and good luck trying to boost it on speed density im prty sure u will just about half to change it over to mass air.
