#1 do i need these or can i block them off


#2 this one i have piece from my 7age but its too long what can i use for this or where do i get this piece from. does anyone have the piece and maybe want to tell me the length of it and a picture????


#3 i was guessing number 2 was for my brake booster maybe ???? can i block one of these off or something



#4 or maybe number 1 was for my brake booster??? number 2 fuel line, is this on the opposite side to a 16v? is this the fuel in side????

1: power steering idle up, plug it, I went a bit over the top with mine:




2: bin it


3-1: normally to the airbox but many people run one of those mini air filters on them, you know the ones meant for cam covers. WHat ecu are you running.

3-2: hard to make out but that looks like the line that goes to your charcol canister, I could be wrong here


4-1: brake booster- using the signal off just one throttle is ok though.

4-2: on a 20v with its side feed injectors the fuel rail is an integral part of the intake manifold, that you see is the return. The inlet is on the inside.

I should write my own technical article about this

in pic #2 you can buy them from toyota. from memory that arent that much. get the 2 o-rings that come with it too. you just need an 86 4age one.

[Sam-Q]

he wouldn't need it though, he just needs to change the O-ring on the RS Chita outlet

nope, wrong...

toyota no longer have supplies of the part...

offtopic to a point but i also found with my ae111 7a build the stock ae86 one is too short and also the angle is completely wrong...the outlet needs to be spaced out about 10mm or there abouts...tecarts make this "kit" to allow it...but had similar bits machined up locally to keep it looking neat..

its amazing how quick stuff can be taken off the stock list. i bought less than a year ago. and the dealership i was at had it in stock.

why would he just have to change the o-ring sam? he needs a pipe to fit the orings too. come to think of it the rs chit a kit has the orings already.

i got one 2 months ago, brand new from toyota, along with new pump and thermostat housing

[H8CHIR6KU]

it wouldnt surprise me if the dealership said that they cant get it cause its too hard to look for or some shit. get the wrong parts guy and they can be like that.

i have been told before cant get thermostat housings. prob the same thing happened. maybe no stock available when tried to get the part.

[Delazy]

i tried to get a bypass pipe and thermostat housing both within australia and direct from japan via jesse...only to be told the same answer both times...hhhmmm...has me curious now...might hit up amayama and see what they say...

i have a feeling 4ac ones are the same.
