Sounds good man, I bet its a big relief to finally see it running smoothly.

 

Yes it is. Now exhaust time!

 

so guys, now doing the exhaust. i got my mani braced. and well from the pic do you think the metal return line is to close to one of the braces??

 

Cool. I saw on your photo page 21, your boost gauge is the same as mine. How are you getting -14 vacuum when mine was only idling at -9??? I am confused. I think it has to do with the fact I have a air filter at the back of my inlet manifold... pretty sure this is the issue for me. I assume your inlet manifold has no filter at the back 3/4" thing?

 

^i do hve a filter at the back of my intake mani. And I was getting that reading because I had it plugged into a port on the intake mani. I just ran a line between the turbine and wg. So now I should have an accurate reading

 

My boost gauge is plugged into thebport next to the blow off valve port on tye manifold it seems pretty accuarte to me but i sill dont understand how i am getting -9

 

the middle pin of the 3 pin fuse box plug is ignition on the sc400. I had to rewire all the ignition components away from the body plug and toward the fuse box plug. It was kinda fun trying to figure out how to connect 13 wires into 1.

 

I knew someone on here had to know the same answer as Dr.Tweak. Care to share how you done it for future reference? In great length?

 

Figured out my own problem, my reading is in PSI

 

so dipping further into this exhaust debacle. i decided to finally get a smaller hotside for my turbine wheel.

there were no ledgible stamping on the iron to tell me what cfm's the original one was. so last minute i went to a local diesel shop and come to find out it was a 18. and 21 was the biggest for the non wastegated h1c.

so i was either going to pick up this item.

or get the used 16 for 100 beans. i decided on the later just to try it out. and to used something new for an downpipe adapter.














the new one does look notably smaller. not too crazy like the 9cfm i was going to get though. also had to cut off one of my mani braces as it was too close to the turbo return line.

 

so back with this crap again. i purchased a sc300 ac condensor(not compressor) from the junkyard for $18.00 beans. placed it inside the car(perfect fit of course). but wait!!!




holy ****. threw away all the damn bolts.. now it's time to hit up the jy again tomorrow i guess. but still need that damn line for a sc400.

in other news. any idea if this black tube can be repaired??






i didn't think 2x about it when i was pulling the engine and it snapped, now.....

 

bump people!!! someone give me a damn answer please!!

 

How much is a new line that you are holding?

 

^^yes sir. but iam gonna have to get a whole new port box from a sc300. this 400 won't work with me at all.

 

more getting hosed on this air conditiong line crap.

so figuring out that the earlier sc300 tubes wouldn't work and the fact that my black tube was broken. i figured id try dremeling one of the port bolt's to try to make it work.




no dice. and the fact that this tube was broke.



so i pretty much needed a new evap core. where the hell do i find one??


LUCKILY!! i went to the u pull it on omaha n.e. and they had a 1994 sc"300" there. heres where the crazy starts. the evap is hidden under the dashboard on the passenger side obvilously.





lots of philips head screws to take out. and here's the evap i need.




these things get very very dirty. dosen't look like they are a servicable item. so i can just imagine how my 180k mile evap looks?

found a guy with a hacksaw and ended up with this finished product




and this has an intact black pipe and all i need. the crazy part is this is the same size as my original 400. wht the fak did lexus make things so complicated between models??
