As on topic. See the two small arrows? What are those two hoses for and what would happen if if my R33 doesn't come with them?

They don't look like they're connected to the heater core.

Looks like the heater core has been bypassed, only a problem if you want heat in your car. If you remove the bypass and hook up the heater core you may find coolant pooling on the passengers floor. The second photo looks like the heater hoses were removed with the engine, this is normal practise but the rubber end caps on the actual heater core tell a story of a failed heater core.

Shouldn't there be two holes on the engine as well since on the 1st photo one of the hoses is being connected there. That means there should be two holes on the engine as well which were not blocked off.

There is. You can see where one goes as its right next to the fitting it connects to normally at the back of the block and the other is at the front of the block but has a small piece of hose that connects it to a metal pipe then the heater hose connects to that close to where the other heater hose connects.

From what i can see (look at images), i don't have that metal pipe that goes from the thermostat housing to the back of the engine >< There were so many hoses that i can't even make out what pictures i was shooting.

All that has been done is to remove both hoses from the heater core, and join the ends with a short piece of steel tube.

Ah! That is right BUT i don't have the 2 hoses that goes to the heater core so the only possibility is that it's bypassed from the engine block side.

      Driveline vibration is resolved. I ended up loosening all my engine mount and trans mount bolts, giving it a good shake then retightening everything and it's gone... Let's just say I was surprised that fixed it.  I've been happily driving it around again but unfortunately put zero time into my direct port/constant pressure WMI setup. I'm on vacation next week, so I'll try and finalize it then.  On a different note, I spent all week fuel/ignition mapping 2x 216L V16 engines. Turbo's were burning glycol and we swapped them out for larger units. We also had planned emissions testing on site, so I figured I'd be there the same week to use their instrumentation and massage any emissions issues out if needed. This was a first for me. Fuel management is similar in certain ways to automotive (i.e air density as load variable) but very different in others. It's all PLC based and AFR's are controlled by air and not fuel. They use a control valve between the turbo and air manifold to control pressure which in turn controls AFR's. Due to this, target AFR tables supplied by the OEM are in pressures and not mass which really through me off. They use air pressure vs fuel pressure tables. I also relied on an O2 concentration sensor the emissions team had in the exhaust. Ignition timing was also all over the place and we were losing a fair bit of power. They're now happily sitting at 16-40BTDC depending on load. We were making about 1600kw at 900rpm at 90% load. Engines were running a lot smoother as well.

      Oil pan for RB25DET NEO Stagea "version"

      meh, it was a good video, clear about the issue and how he dealt with it. A bit heavy on the RTV and very brave to put an RB in anything without rebuilding it first, but otherwise I thought it was good Dose, I'm not sure that having the pickup forward is a big issue; yes of course the oil could shift under brakes but the sump should never be empty enough for that to be a problem (unless you also have a higher volume oil pump, and that oil can't return from the head to the sump quickly enough)

      I'd love a Haltech ECU, and Haltech 10 dash. Was having a chat with Rob and Andy @ Haltech when Rob put one in his MR2. First one I'm kind of interested in too, as you can dim it RIGHT down. Andy was saying bright dashes is one of his peeves too!
