Redline420

I have some pictures and video of what i was told is a 1990 13b na.
Its not 100% complete there are some vacuum hoses that are not hooked up or plugged at all. and some that are hooked up wrong, and some missing throttle components.
Any and all help getting her to idle would be greatly appreciated, i am new to this motor also so bear with me, I am trying to read up as much as i can but i dont even know if its an s4/s5 engine for sure, so im reading up alot on s5 and some s4 engines.

sorry for the punkchewashun im from canada

Bump
Please help me identify and diagnose, I am so close to running and I need this as my daily driver since my Toyota 4x4 let me down.
I can take more pics and videos if needed, whatever it takes.

Here's a vacuum diagram for the S5 NA, this should help you fixing the hoses:

I'm not a FC guy, so can't help on the throttle components.

Thank you my good man!
Idk how u found that diagram I searched my face off but that's exactly what I need so I can atleast eliminate one hurdle I'm faced with.
Off I go to connect the hoes.

Throttle cable in pic #4 is the cruise control cable. It's not necessary to get it running.
I'd also connect the black intake tubes on the left of pic #1. That could be a vacuum leak large enough to prevent it from running.

Thanks for your input speed16, now I know that cable
I suck with these engines I'm so new to them.
Can anyone verify if this is indeed an s5 engine?
If it is I think the people that swapped overlooked some conversion
Procedures, i think I'm missing my line from exhaust pipe to air pump, aftermarket exhaust with cats removed. Exasperating :s

S4's and S5's are difficult since a lot of the parts can be swapped. From what I can see:
-S4 alternator (S4 plug is in back, S5 is on top) and probably harness
-S4 oil metering pump connection (curvy rod in the middle of pic #3) Also means the engine has an S4 front cover.
As for the block, I can't tell you, sorry. But it looks like you have a header, so you should make more power than either series stock NA

thanks again for the input
i have alot of research to do before i can even understand the manual lol
i thought my charcoal canister was the air pump haw haw.
anyways, ive got to learn what all these engine components are called and memorize the abbreviations.

as for the header yes im kind of stoked on the bonus power, i am however not a fan of the sound its going to produce, going to sound great dont get me wrong, just to loud, i like being inconspicuous

il study the faQ and s4 diagrams this weekend
