Here is the dillema. I am in the process of tearing down my RB20DET. I wasn't planning on replacing the oil pump, but I was going to replace the oil pump gasket and the front crank seal. I haven't been able to remove the crank timing gear. I have used tons of PB Blaster and tons of heat to no avail. I haven't seen a puller that I could get around the gear due to the oil pump housing. I used a torch for what was probably way too long. I am able to get screwdrivers under the gear, but I am getting nowhere. In all of you guys' opinions, do you think I would be okay to just forget about and move on with the build? I think so, but what do I know?

I had a similar problem on a RB30 Nissan motor (same timing gear) In the end I had to split it open using a cold chisel along its length. Drastic but at least I got it off!!!! It was severely corroded onto the crankshaft. Apparently its a common problem with Nissan RB motors. Not too dear to buy a new one either - go to a Holden Dealer & get one , about $30 exactly the same as all RB motors size & tooth wise. Make sure you grease it up before you bang it onto the crankshaft.....

      Anyone know this frontpipe?

      But there's the archetype for the name plate! Here's my view on that stupid TÜV ruleset. Buy a brand name aftermarket piece of equipment. In this case, the Mines front pipe we're talking about. Get it TÜV certified on the car. Damage the underside of it, say on a speed bump. Cut out the damaged section, replace with fresh metal. (For the sake of the argument only), continue doing that to the whole pipe until it is all gone, replaced with new metal. Is this grandfather's axe still the same front pipe? The design hasn't changed (much). The pipe walls are in the same places. The flanges are in the same places. It is functionally identical. How does this differ from a pipe that is ever so slightly different in fabrication (ie the number of welds in it, a few mm here and there in terms of where the pipes run, are joined, etc)? Anyone with 0.5% of a brain can see that there is absolutely no way that the performance (power, environmental aspects, noise, etc etc) of it can be any different than the genuine Mines pipe. Maybe even Mines made 2 versions of this design, with the same differences. How would anyone (say a TÜV inspector) ever be able to differentiate between them? And yet, they are so bloody anally retentive about this stuff. Mad. How upset would they be if you had the wrong spring washers on the flanges?

      After a fairly extensive search using Japanese terms and checking Minkara etc, I couldn't find anything even close to your front pipe in the photos. I'm no expert but the two pipes merge really close to the flange connected to the catalytic converter which is rather unique from what I've seen, which makes me think it's more than likely a custom front pipe. The welds and 'more pipe sections than usual for a brand name pipe' makes it seem like a custom one.  Here's some photos of an old Mine's front pipe. You can see that it's just 4 pipe sections as opposed to 6, and arguably looks more like a 'production' front pipe:
