Fuel pump is fine for now. Use the fine search function with the keyword turbo and read, read read...

I agree on the fuel pump, as for your turbo plans I don't have experience in that field but hopefully someone here can help. Good luck!

for now you can get by with stock fuel pump. But when you turbo it your going to need one. I would get a 255 walbro. Your going to need some fuel injectors too. Get some 450cc dsm injectors. Also your going to have to tune it. Cheapest software out there is crome. Convert it to obd1. I have 88 ef convert to obd1 with turbo ls vtec right now, but had two turbo single cams before that in my ef. So if you need any help let me kno.

also will i need an si dizzy or is the oem good

if MPFI you need the EX or SI dizzy but you will have to use the plugs you converted on the motor harness for plug and play

your going to need a obd1 distributor to convert it over obd1 . what head are you using? vtec or non vtec head? they make distributor plug adapters you can buy to make it easy or you can make your own.

dont forget to keep the OBD of your dizzy and ECU the same, remember obd1 and 2 can use each others dizzys but obd0 is a standalone and wont work with any other ecu since the crank tooth count is different so if you start using jumpers make sure to have an ecu to match or you'll get NO FIRE

i have obd0 non v tec, will any 90s sohc model dizzy fit or will i need certain year also the ecu is the oem i wired it with the dizzy going to b10 and b12 on the ecu, so ill need dizzy and connector

so you did a dpfi to mpfi conversion on it. do you have any cel codes coming on?

Not yet still in the process of doing it almost done just need a ex or si dizzy

ok. once you get it to mpfi then you can convert it to obd1. for now though you will need the pm6 ecu and the dizzy off a ex or si. when you turbo it i highly recommond converting to obd1 and getting it dyno tuned. this will make all you money well spent and your motor last longer.
