My APS TT build
Well over the past 6 months or so I have been selling some parts, buying some parts, and mainly waiting on the APS kit I bought second hand (but in awesome shape, VERY low milage, etc..). Some of you know I had and top notch AFR heads/big cam/FAST 90/and a very nice nitrous setup previously, but decided that I wanted to go the FI route.
I swapped out the AFR heads with stock 317s, changed the cam to a Dallas Performance spec'd TT cam, and changed the intake to an LS2 unit. I also added a Meth kit from Dallas Performance and converted to a return style fuel system with a FPR at the rails. Other additions were a new Tick performance adj. master cylinder and a electronic boost controller. Overall its been a long process but I have been patient, knowing that it would all payoff in the end with a big smile on my face.
I have a few misc. parts to get from the dealer tomorrow to finish it up within the next couple days then It will go to Taylor at Dallas Performance for the tuning.
I have a few pics here but Ive been working like crazy to get it done so I kinda neglected a good detailed photo album. Yes, the car is FILTHY, as it should be for sitting 6 months. It will get the best bath/cleanup of its life when i get done.

I know it has been a long hard project for you Chris. I can't wait to see the results. Good luck finishing up! With the low compression heads, still good overall compression, built motor and the cam, it is going to be a blast

WTF!!!!
Are they BB turbos? Oil and water cooled. Are you sure the water is hooked up to the right one?
Edit*
WTF!!
I just re read that. Need to get my brain right. So water is moving out the exhast side?
Pull the plugs and look for water, do a compression test and do a coolant pressure test
Has this ran AT ALL since you put the turbos on??

pull plugs, DO NOT CRANK!!!!
find wet one. IF no wet one do coolant pressure test first
I would almost guess head gasket but still makes no sense.
Have you had the heads off since starting the build?
Are you SURE the turbo did not have a cracked center leaking the water out the exhaust?? Either way you should hear and see where its coming from with coolant test
Water cooled turbos?? If no then rule out cracked cartridge.
Water in oil?
Wish I was closer Id give ya a hand at it.

Yes, coolant enters the turbos from the passenger side head, then from that turbo it crosses to the drivers side turbo then back to the big coolant plug in the drivers side of the block.
I really dont know what else to think other than a seal or something
???
Broke my dipstick tube so I cant check the oil, but I need to drain it anyway.

Ouch. What's the history on this kit?? Are you absolutely sure that you don't have the oil and coolant fittings on the turbo's swapped??? Is it both sides or just one side? How much coolant did you get into the car before it started to flow out?? Reason I ask is because it would have to be pretty full to push all the way up to the head to flow out.

Im pretty damn sure I dont have any of the fittings swapped.
It is only the pass. side turbo. I filled it until it was full before I noticed it leaking out.

Well.......try pulling and capping the feed line for the turbo's and refill.....see if the pouring continues. Can narrow it down really easily that way.
I'm not even sure those lines can be swapped.
