Building a TPI 350, blew up my old Carb'd one. Spent waaayyyy too many hours in the garage reading posts titled Should'nt be left alone... Decided I wanna try and FI this TPI. M90's are all around for short money and if I use the same method's I've read about what else do I need? For example, do I need to upgrade my injectors? It's a MAF engine should the MAF stay in stock location, and if I mount the M90 and line everything up will I only need to get a longer serp belt and a tensioner? Also I think I know the answer to this one but I'll ask anyways, No driving without a tune right???? Any info would be awesome the engines sitting on a stand in the garage, engines up in the air on my lift, and I just get to stare at them until I get my wiring harness. Atleast they'll be painted on every services.

 

i would use the megasquirt II for tuning and toss the maf. and yes bigger injectors. i would set the spark table to retard 2 deg per psi.
