i got question i got hatch with ls in it putting a turbo in it had a question about the esu what should i do should i just run and fmu and retard the timing with msd btm or cam gears will do the job or what? i am only going to run 7 psi-9psi

 

this will be corrected if its wrong, but id guess you should do:
-walbro 255 pump with upgraded injectors
-stock dizzy with decent wires/plugs should be fine
-cam gears would prob be a good idea
-adjustable FPR would be a good idea
-run a socketed/chipped P75 (OBD1 LS) tuned for your setup

no FMU, tuner will set the timing, and just out of curiousity, what's a MSD "btm"?

 

MSD BTM = MSD boost timing master. it retards timing per pound of boost according to a preset setting which is controlled by a knob, i think its adjustable 0-3 degress per lb. i wouldnt waste your money on this as all ROM editors can adjust timing to your specific motor needs and do not require a piggybakc like the MSD BTM

cam gears are not necessary but wont hurt. if you cant install them yourself and arent getting them for cheap i do not think theyre worth it, use the money elsewhere.

fuel pressure reg also is not necessary. i wouldnt waste your money on a pos B&M. if youre getting an adjustable regulator get a quality one or just leave the stock one on there as it will work perfectly fine.

also you can use either a socketed P75 or P06, doesnt matter since there will be a custom program on it anyway.

other than that the above advice is fine
