you could also T-off a coolant line. That's what I've always done.

 

Its better for the life of the turbo and you wont need a turbo timer if you run coolant lines

 

exactly what i said

 

Eh, any help on the location, like I said I think the pic in that car is the 90 crx si, so maybe if you could point me in the direction of the lines to take on meh 99 civic ex, like what size the lines are im looking for etc, cause theres two hoses coming out of the firewall, but they are fatty...ive found the one 3/8 line coming from the tb, which acts as the in, but cant find the out...help

 

find out were the line goes. if it goes to the t-body disconnect it.
connect it to one of the cooling ports on your turbo.
the other cooling port on your turbo gets routed back to your t-body, its your return.
i have a 94 del sol and can see them if i look behind my intake looking down in the firewall. 2 lines going out.
if i were sitting in my car it whould sit right in front of where my shifter or radio is. use any one of those lines.
you dont have to use the one to the t-body, you can use the other that goes to the block. just make sure you make your coolantant return there.

heres the stock setup
-----------cooling line to t-body or block-----------------------------------t-body or block
heres the turbo inline
-----------cooling line to t-body or block------------turbo---------------t-body or block
if you still cant find the lines. just a fatty coolant line and put a 2 port copper tee in it. use pex or polly adapters in the ports. it should work fine
thats the best that i could describe. good luck

 

yea most ppl run in-line with the coolent lines coming off the TB

 

It's way too easy to do for you to ignore it. Hopefully all this good info helps you out.

I would reccomend you look into upgrading your cooling system if you have any kind of overheating problems because adding a turbo to the cooling system of an N/A vehicle...that can be rough. Keep an eye on that gauge.
