Water lines .... I am confused

[garagefujimoto]

I've had the stock turbos off for so long I can't remember what goes where, and what I can block off or loop with my single. I want to weld the not-needed ones closed, because I don't trust rubber caps from the auto store.

I see 2 water connections on the upper water neck, one on the bottom of the water pump, one on the side of the block toward the back, and one on the metal water pipe leading towards the back of the block.

Even a sideview of a stock 1JZ would be great.

i'll snap a picture of my 1jz setup for you

the two water connections on the upper neck go to each turbo; the forward most connection runs to the rear turbo, and the rear connection runs right to the front turbo.

the hose below this connection is the coolant line that connects to the bottom of the forward turbo.

the one on the side of the block is questionable...i'll get back to you on that one.

pic's to follow, just need to shrink em down

here you can see the hose coming off the waterpump connects to the metal line off the turbo. you can also see the two lines coming off the upper coolant pipe.

here's another pic...note the two lines coming off the upper coolant pipe.

and here is what the rear turbo coolant line looks like.

you can almost get a good look at my custom 3" downpipe in this one. the "custom" stock 7mgte dp that came with the car wasn't working for me...

let me know if you still need any other pics... i.e. with the intake removed, or from under the rear turbo.

OK, yeah, the 2 on the neck are the water in's and the waterpump one and the rear metal pipe are the return's.. what about this stinkin one on the block LOL

i dont remember any coolant thing on the block down where you had it circled int the pic, but i can go take a look in the morning on mine.

as for the water neck and the rear one on the crossover pipe, i cut em off and welded them up

 

[garagefujimoto]

Yeah, the first 4 I am gonna cut off but that last one..I dunno LOL

I think that last one on the block is oil feed for the rear turbo.

 

[garagefujimoto]

Hmm.. I thought the feeds were banjo connections, I already have the rear plugged and AN in the front
