Blacktop 20v, what are these hoses

[jet81j]

thanks for the info.

yeah i have the o rings from the RS Chita kit.

that piece for the water pump and top outlet is that straight on the 4age's?? you can see in the photo the one i have for the 7age is offset or camshaft style


i'm also runing a Adaptronic ECU

As in my previous post i found the same issue and as a result did the same as tecarts did by spacing the outlet out and running a longer pipe...

Quite interested to hear about your motor...as my ae111 7a is just about complete...

delazy - he is doing a 4age not a 7a.

jet81j - yeah a 4a one is perfect for what you need. it is a straight pipe with the cut outs for the o-ring and it is shorter. its a bit of a tight fit so you will have to take off the top outlet and back of the water pump so you can slide it in, while still getting the top outlet onto the studs. i also used the rs chita kit and if i remember correctly, i got rid of the studs and used bolts instead. made it so much easier to fit.

yeah only doing the 4age. i'll keep the 7a bottom end for later. i'm thinking 7age 20v would be a very good na engine if built right, my 7age lacked topend and the 20v head would give you that

yeah i got rid of the bottom stud, it was too short for the top piece anyway. i'll just make a straight piece then at work just a bit tricky to measure the length

theres a butt were it bottoms out in the water pump and i think in the rs chit one too. measure their depth then measure the gap between outlet and pump. presto

Oh my bad lol :$ sorry..guess thats what i get for using forums via iphone on the go, glance not read lol

[jet81j]

How about this thing do I need this or can I Block this whole thing off

[Sam-Q]

you want just a pipe with O rings on either end?

[Delazy]

nah, im already sorted...machined one up...just curious as to whether or not they are discontinued or not...as my discontinued answers were from quite reliable sources...not the local lazy parts bloke at the local dealership

i tried a good 12 months back when i bought all my oem bits for the motor...

[H8CHIR6KU]

12 months back was about when i got mine off the shelf from toyota dealer...

that image in you second last post, i take it your talking about the hose that you got going to the block with out a wiring plug in it? if so id recommend keeping it connected to the outlet of the throttle plate and just putting a filter on the other end. you dont need to wire it up, but without it it makes it hard to idle properly
