I read through some of your info but Ive done a few swaps before. Did one in a FC and I rushed it and cut corners but I picked up another FC shell and building a track car
YES ive searched, wayy too many mixed answers...im hearing 140psi all the way to 200psi!!!
Im in the market for a 1jz swap and found THE perfect swap on ebay from a reputable company.
They told me 145-150 across the board, obviously cold and dry (no oil or ATF in chambers)
soooooo wttttffffff
I was checking wires and one big wire coming out of the fuse box and going over to the harness where the alt is came off, I put it back on and it's still not charging
I'm not good at wiring and have NEVER messed with a supra/1j harness. Damnit. I've been sriving it like that for a while and nothing tho and now all of a sudden this?
Got a new alt on and battery tested and charged. Voltage is now I'd say 11.8ish. Took it for a short drive and kinda goes up to 12.4ish then down to 11.2-3. Obviously goes down some when I turn on lights/fan/etc. Then turn signals the voltage drops then goes up then drops as the blinker is...
so tonight i was driving home, battery light comes on and within 30min the voltage dropped from 14 down to 7.... all connections/wires look good. i didnt do the swap so dont blame me but i took the fuse box cover off to take a look at the alternator fuse....the guy who did the swap jumped the...
ok, so i got my supra with no radio/cd player but had stock plugs still attached....just bought a used JVC cd player....
here are the diagrams...

whats the proper idling pressure for a stock 1jz? it seems like mine is idling just a little low and vaccum is only at 12-13 at idle but 19-20 at decceleration. runs fine tho
