strikes me that I should measure the deck height. How would I do that? I used a caliper inside each piston to measure the stroke depth and it looks like I'm down on average 0.3mm off of spec. I have a stock sized Cometic head gasket (1.37mm). I haven't measured the head yet but that won't be zero.
Looks like I should go for a 2mm gasket. The HKS ones are serious $$, Titan/Cometic seem to be OK and well received.
Unrelated note - Looking for some adjustable cam gears.
Put the intercooler and the Mashimoto radiator on:
There was tons more to do than I remembered. The instructions on assembly where it says "do reverse of disassembly" is only useful if you remember how you took it apart Thankfully we took a *ton* of photos.
Upper intake manifold + vacuum lines + wiring harness took a bunch of time to diagnose wtf was going on since it was all in pieces on the bench. I'm so glad that I labelled all the bolts into bags as things came off. Made assembly slightly less painful
Coming together! Upper intake done, lower rad hoses and intercooler piping (total bitch!), coils+wires etc.. The CPS cover just disintegrated so had to order a new one
Got some temp insurance then went out for a drive back to my apartment
Things left to do:
- the idle refuses to work. I've checked vacuum lines, it runs when I unplug the ICV but surges between 1k-1.5k rpm which is annoying. Could be the TPS
- wire up the electric fans. Turns out the fan Mashimoto "kit" comes with nothing :/ Gotta order the temp sensor and wiring kit seperately
- get timing done. Right now the CPS is on 0
- drop oil + coolant another time
- wash it
OK, still can't figure out the idle problem, but getting closer. I picked up a vacuum tester and tried a few spots around the engine.
Cold and at idle (ish )
FPR - 15mmHg
Back of Intake nipple - 15mmHg
Throttle body right side - 0
Throttle body left side (which goes to BOV) - 0
From what I've gathered on the internwebs, It should be around ~20mmHg at idle.
Potential problematic spots:
valve cover breathers - I replaced those with ugly generic coolant hoses
accordion hose to passenger metal tubing - I have an aftermarket metal turbo intake pipe and at the cross-pipe doesn't quite fit right, but it's new
cold start injector - I didn't have the gasket so use make-a-gasket to get the car running. Could be leaking
VSVs - I hear suction sound beneath the intake manifold at idle, but not sure if that's normal on cold start.
I checked all other vacuum lines and they're all connected fine and look OK.
Did some search - looks like on startup there should be no vacuum on startup to FRP via the vsv. Based on my measurements that's wrong. Looks like my FPR one is defective.
