Took the spring in the wastegate from 18psi to a 9psi combo.
Old setup.
Turned the attention to the BOV. Pic for reference.
Torque update: Retorqued this morning to 85ft/lbs. Some are good, some have a bit of creep. We'll see what we get tomorrow AM. Once the head bolts are all snug the new OEM timing cover housing bolts will go in with blue loc-tite to 89in/lbs if I remember correctly. Then the cams.
Ordered an EBC and acquired all the hardware to hook her up. Going fuel lines instead of braided this go round for vacuum.
Also rounded up fuel lines and fittings for my billet fuel rail. that has been collecting dust.

Making the earth ground for the megasquirt.
Ready for the strut tower!
Getting ready for wiring up the traction control. The brown ABS wire is the ground for the sensor??
Don't mind the bent valance.
Torque Update: There are 4 studs that have a slight creep in them. I'll re-torque tonight. Getting close!

Multi-port is ready to go. Need to install the rest.
Ceramic Coated Exhaust Housing!! By Snap
Port matched the turbo exhaust flange. Hours could have been spent porting this thing. That's a January 23rd project.
Cleaned up the turbo.
Pic for filter reference on the S54 filter housing.
Torque Update: Done. Time for cams.
I need to figure out which oil cooler output on the S54 housing is the hot side.
Last night I took out all but one of my exhaust manifold studs. The one wasn't moving at all. Sleep ensued then in the morning brake cleaner was sprayed in all the ports and compressed air blew out the debris. Did this process one more round.
More to come!

Cams!!
Used some tape to hold the caps in then flipped it on the studs.
Intake cam in the sweet spot.
Done! All torqued to 11ft/lbs.

Timing done.
Valve cover on.
To do list:
- Exhaust manifold
- O2 sensor
- Intake manifold
- Weld meth bung on intake piping after the MAF sensor.
- Run wires to new IAT sensor.
- Radiator
- Ground PLX wideband module to the chassis ground that will be shared with the megasquirt.

Looking awesome.

Thanks! It's coming together.
Tonight all the exhaust manifold studs were red loc-tite'd into the head. Replaced the O2 sensor but the connector is from an older PLX unit. I'll get that sorted tomorrow.
Debating whether or not to run the megasquirt right away. I would be tempted to drive it but I think I want to start with something I know works then swap to the megasquirt asap.
My neighbors have to be getting annoyed with me and my air compressor that is constantly running. I need a bigger tank!

Wiped down the gasket surfaces with solvent.
OEM S52 gaskets.
All tight!! Took me 1 hour.
Wastegate, downpipe, turbo and oil return line all tight.
Electronic Boost Controller/Wastegate lines ran. Need to wire it up to the Megasquirt still.
As she sits for now. Going to get the meth bung welded on the charge pipe and do some actual work as well.

Pre-throttle body .7mm meth bung.
At my welding guy's (Dan the Exhaust Man) shop. He is putting a full cage in this at the moment.
Intake manifold ready to go!
As she sits now. Need to get the cold side piping tightened up, run the meth lines to the trunk and finish the engine part of it. Lastly install new wideband O2 sensor harness when it is delivered. I'm sure I'm missing some other things.

Do you have a solenoid on your water feed to the intake manifold? It was probably in the thread earlier but what water/meth injection kit are you using? My Volvo might need some...

I pieced together a kit from Howerton Engineering. They have a fast acting valve solenoid thing that I'll have megasquirt run. They sell full kits as well.
With that said I have a 60psi pump for sale on the cheap.

Lookin' good m8

Still burning coolant. Guessing that the deviation in the block didn't come out with the block prep... I'll get in there this weekend to see what the spark plugs look like.
Getting to drive it was still fun. It rips pretty good while laying a smoke screen.
WTB:S52 motor
Thinking that I'll get new rings on my Imagineering pistons. Swap those and the K1 rods over to the new crank. Drill and tap the head studs out to a bigger size (I think Boris with the 8 second e30 is running RB26 ARP studs). Punch out the bore to 87mm then machine down the block surface. Slap the head on with a cut ring gasket and try to blow it up!

Or should I buy a new head, machine my block down to level and go from there?

I've got a buddy who swears by this stuff.
800+whp LS motors, 700+ whp 4G63s, etc. He really globs it on there - may be worth a try,
