Installing scm3431 DBB turbo

[rated x]

I just got my scm3431re today and wanted to touch up on a topic I seen on installation in the tech article part of this forum.I wanted to find out more info on tapping onto the water line.First question would be ,why can't you just use the same lines coming out of where they are now(stock)?Does anyone have more detailed pictures on the water line installation tapping?Will this work better?Thanks.

I don't know if you saw my writeup or not, but the only reason why you wouldn't use the stock water feed line from the block is because the to4e compressor cover will not fit with the stock banjo bolt in. If you can make it fit (some PTE's will work) then by all means use the stock feed.

If not, you will need to find an alternate water feed line (tstat housing).

Thanks for clarifying that.I thought it had something to do with coolant flow restriction or something.I just ordered the coolant lines and should get it today.Another concern I had was if I tap into the t-housing,isn't the coolant coming out of there hotter than the original location?

The stock water feed line comes from the block. The water temps should definitely be hotter there than from the Tstat.

p.s., 2k miles on my BB5031 with my setup and no shaft play or smoke

As I was taking my old 16g off I noticed that the lines for the coolant is one is coming from right under the cap on the thermostat housing and the other is coming from the coolant pipe that runs to the water pump behind the exhaust manifold.Do I have to plug the hole coming from that pipe behind the exhaust mani. and then tee the hose going to the oil cooler line to the turbo?
