Help, is my motor done! *update with pics*
So I was street tuning my buddies car and BOOM, car dies and a crap load of white smoke is coming from the exhaust. We were doing a 3rd gear pull and around 7k rpm it just lost power and died. Car can't idle and when it runs it runs like crap. We ended up towing the car back to his house and found #2 and #3 spark plugs were soaking wet. There was no coolant and the oil was like coffee. It was too late to take apart the motor. We're probably not gonna work on the car til monday, any ideas what kind of damage we should be looking at.
motor:
B18C
eagle rods, 9:1 srp pistons
arp head studs
t3/t4 turbo
skunk2 mani and tb
750cc injectors
2.5 bar map sensor
crome pro
We tuned it, 14.5 psi perfectly 11-11.5:1 afr
but 20 psi, thats when it died. afr was still 11-11.5:1
using a step retard for timing
any thoughts?

Just took of the head and....cracked the #2 sleeve, big time. Can the motor be salvaged? Any advice on what to do next?

Sounds just like my car during 5th gear pull after dyno tune, during the partial throttle street tune.
Cracked sleeve for sure.

Re: Help, is my motor done! (EJ8Coupe)
I bet a sleeve blew if you have coolant. I've been in a car when it happened....kinda scary .
Pop that head open and see for yourself since you are going to have to anyway.
20psi on what turbo? What kinda gas? pics of the map? Lost fuel pressure?
usually 20psi putting down a lot of power and shouldn't be tuned on the street until after a dyno run and only done for real-life AF adjustments
edit: Opps, I didnt read I guess you did crack a sleeve. Any pics of the piston? We can tell you if it was det. or power that did it

Well, we tore down the block to send it to AEBS and get some sleeves...
#2 sleeve cracked
#2 bearings toasted
Now new bearings are needed, do I have to replace all the bearings or just #2
bearings? All the other ones look fine. And does the crank need to be fixed?

go to a machine shop....w/ the pistons and crank etc.
ALWAYS replace the bearings (all) anytime you have a problem...just in case.
