s/c Un-Install

clown - keep a listing, please, of everything you gotta put back in. Thanks. Also would be curious to know if taking it back out changes any of your vacumn flow as I couldn't find it anywhere in the manual but it seems like the sc changes it.
Junk, I just sent you an email to "yourLandCruiser" with photos and stuff. There is a change in vacuum flow and I'll post it later.
<edit> Mark, I sent them to you too. Mark has a pdf from George S. with the specs on building your own sst for the crankshaft pulley.
Short list of what you’ll need:
(1) large coolant hard line (can’t remember what this is called right now) that runs along the top of the exhaust manifold. This also has to have the gasket replace each time that sits on top of the thermostat housing.
(2) small #2 coolant bypass hard line that runs from the underside of the throttle body to front of block (where the s/c belt tensioner goes. George S. correctly identified that you could remove this non-destructively by loosening the distributor, but it helps to have it loosened enough to not only rotate it but pull it out ¼” or so too. I also had the alternator loose and I think that helps too. It can be removed and installed this way but it’s like one of those Chinese puzzles.
(3) brake booster nipple that goes on the intake manifold. Replaced with a allen (5-mm) plug with s/c
(4) intake hose from air filter assembly to throttle body
(5) original radiator cooling fan
(6) original radiator cooling fan mounting studs. Longer ones were used on the s/c along with the aluminum spacer to move fan our closer to radiator.
(7) Hoses. Lots of the vacuum hoses were cut, replaced, etc. Most importantly was the brake booster one. It’s a really odd size and you cut it to install the s/c, and what’s left won’t quite make it back to the nipple installed on the intake manifold. I had a hard time finding it sold by the foot.
(8) Throttle body gasket.
(9) Bolts. It helps to go through the s/c install manual to realize what was re-used. The two long (lower) and two short (higher) bolts holding the throttle body on are easy to forget.
I'm sure I'm forgetting other stuff but right now it all is running fine except the obvious change in performance. As for that, there has been a lot of discussion about the stock setup, the supercharger, and the turbocharger. Pretty soon I'll have experienced all three on the same truck with the same setup but for now I can say the supercharger definitely feels like it added the most right off the line from 1000 rpm. I haven't seen the power curve of this supercharger on the 1FZE compared to stock but it feels like it must taper off a bit once you get above 3500 rpm. But I do know that from a stop or trying to go over a large rock you can feel the absence of that supercharge
The only bonus I see from going back to stock is the amazing amount of room in the engine bay. There should definitely be NO complaining about working on your truck if you don't have dual batteries and a s/c or turbo stuffed in there.
