I have a 90 civic s1 with the d16a6 and im planning on puting a t3 turbo on it (.48/.48) and i was going to run 8 psi, i already have a walbro 255lph fuel pump and an adjustable fpr and a vortech 12:1 FMU and what i need to know is will i need to do anything more for fuel and would i need to do somthing about spark/timing like a msd btm?

 

Get some DSM 450's, you can get them for real cheap used. And I would go with something other than the FMU for all your fuel/timing needs. Uberdata is what I use, others use Crome and turboedit. It all depends on what tuners use in your area. Find out what they tune with the best and get that.

 

i use uberdata as well, but seeing that you are obd0, id go toward turboedit

 

Since you are OBD0 go with TurboEdit for sure

Do some reasearch on TurboEdit and get rid of your FMU, your engine will thank you for it! It will run smoother, safer, more reliably, and have more power.
