so ive decided i will be running OBD1 with a professional tune then trying my hand at it later down the road
i have my old P06 ecu from my 93 cx im going to have chipped by phearable.net for crome
i will replace my fuel pump since it seems like a $100 well spent
i know i need a conversion harness for the ecu but do i need it for anything else? i thought i heard something about a dizzy jumper or something
and since my injectors are peak and hold and the dsm's are peak and hold do i really need a resistor box? ive been wondering about this
and cvcrcr99 thanks but that ecu wont work cuz im nonvtec yea! lol

the injectors you will not need a resistor box because you already have one if your obd0
and also get a fuel pressure regulator you should have it at about 30-40psi
the d16a6 is a good engine to boost they have concaved pistons. i would get a thick head gasket to reduce compression and the head bolts. the internal wastegate boosts from 6-8lbs.

because your upgrading the fuel injectors and they run on a different amout of psi than stocks. i have always up'd my fuel pressure when i went boosted.

no the stock fuel pressure regulator will just return the over pressure fuel back to the tank.
fuel pressure will stay the same.

Are you able to tune yourself with an s100? I thought only certain dealers could do it. That's why I thought everyone wants either the s200, or s300.

aem are good fuel pressure regulators. try to find a direct bolt on that bolts to your fuel rail
the ones i usaully get i have to cut my stock one in half and attach it to the bottom part of the stock regulator.

something like this would be good and dont forget a fuel pressure gauge

You may get lucky and find a chipped p28 for under $160.

OP, you probably want something like this:

It all depends where you look, I had a chipped p28 w/ a custom chrome basemap for $65 shipped and $35 for the conversion harness.

No of coarse im not including the actual tune it self in that cost lol
