My L26 Performance build
#11
start building it back up from the ground up. getting every thing that you would want on the bottom end better conecting rods and pistons and put in the cam at the same time. i would look up the type of pistons for a 3800 supercharged to see if you could get the pistons so that the boost would take from a turbo
IMO- you've got a good low mileage bottom end- just leave it together. Stick a cam in while its out, upgrade whatever other bolt on parts- but leave the crank/rods/pistons together to keep reliability up.
the 3500 i got back from the machine shop can take boost from a turbo a small one takes 12. the one from anouther member here his about 8-10. if i have a really good blow off valve for it.

That thing must have been running awfully rich to leave that much deposit on the pistons in only 1,000 miles. Since you found water in a cylinder I would do a complete tear down, tanking, magnaflux and have the decks checked for straightness at bare minimum. Were there any obvious signs of a head gasket failure when you pulled in apart? New heads will insure they are flat, but it would be a major bummer to put all that time and money into it only to find out you have a warped deck surface.

I don't think its that bad.
I finally got the HB off and the timing cover off. Timing chain looks almost like new. Ill get pics and post them.
If I decide not to do a complete tear down. Can ii clean it with the pistons in it?
#15
Heres some pictures I took.
HB off finally.
Time chain ( I think it looks really good)
Timing chain damper ( I dont know about this . about how many miles would make these marks.)
Heres a look at the crank
Oh yea I forgot to tell yall, when I drained the oil. It had water in it.
EDIT......
I pulled out the camshaft
I just ordered a rollmaster double chain timing set and the stage 4 turbo cam.

you may be buying it already but i figured i would remind you if you forgot. buy a new cam bolt, there stretch bolts and cant be reused. also are you using arp head studs?
#17
i am waiting for the money for a blow off valve right now yea right now it is a small one but not a crazy small one. it is the main reason why i didnt put the engine in yet i wanted to get every thing first thats all. sorry if i stoll the thread just giving bumpin a status and the why i hope you dont mind.
#19
I havent got that yet, I will buy that when I buy the 2 front cover gaskets. I am also getting the arp head studs also, just later down the road.
Thats what I figured to. Im also going to have the cylinder heads checked, surfacing if needed, and probably PnP.
#20
Guess what came in today. My STG 4 cam and double roller timing chain.
I still need to tear it down to get the block cleaned. I think I will do that myself to save money. I honestly think it has more miles then 1,000
Edit.......
Update
Well I decided to tear down the rest of the motor. I wanted to see what the bearings looked like. I took lots of pics.
Heres the knock sensors.
#5 piston and rod bearings
#6 piston and rod bearing
Crankshaft and bearings
Main caps and bearings. ( Left to right= 1-4)
#1 main cap bearing
Engine block
Next on the list to buy is bearings.
How do I get the core plugs out?
