2 questions... fuel rail, and water lines
 

#1: fuel rail.
I saw this on lightweightmiata
http://www.lightweightmiata.com/fuel/fuel03.jpg
I have a spare rail and I was thinking about doing this but I dont quite understand where the far end goes? or how is it hooked up... is it just a "T" fitting that goes to both ends of the rail?

#2:
I have a 16g turbo and I was wondering where is the best place I should go for my water feed and return. I've been looking at all the pics I can, but I havent found one big/clear enough to copy or refer to. any info will help.

thanks

Yes, it would connect to the front-feed via two lines and a tee fitting with a line from the fuel feed from the tank.

I was thinking of running a tee of one of the heater hoses and hten running a return line to the coolant bung on the block. i Just never did it though it should work.

Oh, I forgot to respond to this one. When you get a moment, just grab a shoplight and look at the front of the engine block just above the crank pulley and to the right (it's been a while, but I think that's the general location...actually, the bosses may be coming straight off the water pump housing, I can't remember). That's your coolant feed and return, and it doesn't matter which is which for the turbo.

Here's how mine looks:

make sure it don't leak.

braineack : perfect pic, I can make that work no prob. no leaks ;)

bripab007 : here is a pic I made from one of fm's pics.
Is this what your talking about? and it doesnt matter 1 or 2 can go to either side of the turbo?

Yes, great pic; that shows exactly what you need to know. Yes, those two lines are the water lines to the turbo, and they can be in any order.

SWEET! thanks!

just like 48 other mystery steps to go! not really, like 4 :P

Just ask if you need help. Or you can ask at M.net and get about 600 wrong answers.

preaching to the choir. its why I ask so many dumb questions here.
I leave with the right answer :bigtu:
Instead of leaving m.net with maybe the right answer sometimes :ugh2:

althought it doesnt really matter, id put the line to the pump on the higher fitting of the turbo and the one from the t'stat housing on the lower..just to get slightly better flow through the turbo...I.E water flows from lower to upper part of the turbo housing...

There shouldn't be any "higher or lower" fittings on the turbo because the oil drain should be at the six o' clock point.

He got you there! With a -+ 10* margin of error.

I think a little light-bulb just went on above my brain.
Does the picture of the fuel rail illustrate what it means by "dual feed", ie... pressurized fuel is fed into both ends of the rail... as opposed to a single feed where the injector at the far end might be in danger of being starved.

Yes... dual feed rails input fuel from both the normal cylinder 1 point and a cylinder 4 point to make sure that all the injectors are getting "equal fuel". <G>

Dave,

exactly what happened to me. Im going to pull my spare fuel rail this weekend and give it a shot, I need ot go buy a tap/bit set this weekend anyways for the oil pan tapping, Ill just find 2 :)
