Boost and A/F?

I am putting an 88turbo motor in my 86. I have an intake, 3 inch RD DP and exhaust, lightened flywheel and clutch and walbro fuel pump. what else do i need to do to not wreck this engine? i was thinking on running at 10psi, is that safe considering that i dont have an A/F controller or any way getting more fuel into the car, other than the fuel pump? Has anyone done it safely?

thanks,
jose

1) Professionally cleaned injectors!
2) Good solid voltage at the fuel pump - usually means doing the fuel pump rewire mod.

You need to port the hell out of the wastegate, to include having a bigger flapper door put on it if you want to keep it at 10 PSI of boost with a 3 inch downpipe..

My TII ran mid-low 12's with the walbro, stock ecu and injectorsr @ 10 PSI, you should be fine as long as you keep it there!
