Day 3:
Today started with some more manipulation of my oil return hole. Eventually we got the fitting in and sealed it nice and tight with some Teflon Tape and a quick squeeze of RTV on the edge, just for some extra assurance.
This was after a run to an aircraft supply shop nearby for some more fittings. We eventually put together a set of fittings that takes my -5AN threaded coolant banjo and ends with a barb of the same inner diameter which will attach to the coolant hose once the turbo is in (which will be sometime within a couple of hours of starting work tomorrow).
Somewhere in there Brian and I mounted my intercooler. I'm using a JohnnyRaceCar new-style 6in core intercooler, as per the recommendation of RED_DET. It has 2.25in end tanks which will mate to 2.25in IC piping which will narrow to 50mm (roughly 2in) at the exit from the turbo and at the BOV. Eventually I'll get a larger turbo intake exit pipe and a larger BOV to match the larger piping - this will accompany a boost increase.
Well, I think.
Here's the strange thing, this wastegate actuator doesn't seem to say Nissan anywhere on it (I didn't look too closely, I'll check tomorrow and ask the original seller of the turbo if it's stock). Of course, Garrett made the turbo, so that could make sense, but I'm not sure how to tell if this actuator is set for stock boost or something higher. I'll figure that out by the time the car is running again. I'm pretty certain my 34lb (360.4cc) MSD injectors (had to have something to fit my top-feed lowport rail that was very low impedance) will be able to handle it if that actuator is set for some higher PSi, but I'll have to check that too.
Anyway, after mounting the IC and making sure it sat pretty in the bumper (which it does, I'll have to trim a little of the bumper brackets where it bolts to the lower support, but it's not more than a little corner to remove, which is nice, and that's only to get it off the IC bracket, so trimming isn't even entirely necessary), we pulled it back off and painted the holes we'd just made in the bumper. We needed a right-angle attachment to get the upper holes drilled. By the way, the bumper support seems to be steel, so it was a beast to drill, but it can be done with some determination. Then the self-tapping screws became an issue since we didn't have a good angle to get them to bite. Once again, a little determination and elbow grease goes a long way.
It turns out that the lower bumper hole is almost exactly the size of this IC. We'll be able to see the silicone joint between the end tanks and the piping, but not more than a sliver of piping, and vertically the IC doesn't interfere with airflow to the radiator, while also not getting cut off from air by the top of the bumper.
In short, this size intercooler is absolutely PERFECT for a B15.
Anyway, after getting the oil return hole the right size, we used a combination of a shop vac, compressed air from an aerosol can (shoot me), and a sliver of sock drenched in carb cleaner to make sure all the shavings were out of the hole. Then, after scraping the surface of the bottom of the block and all the oil pans with a PLASTIC scraper. I can't stress using PLASTIC enough, at least on the aluminum pan and block, because a metal scraper will scratch the surface and possibly lead to a nasty, frustrating, messy, and destructive oil leak that will be equally painful to fix, we RTVed both the upper pan and the block and seated that, bolted the oil pickup in (making sure not to forget the gasket), bolted the mid-plate between the two pans in, then RTVed the lower pan and the upper pan's lower surface and bolted the lower pan back in.
Then we bolted the front-to-rear motor mount brace back in, and started working on the previously unbolted rear motor mount. It isn't tightening all the way, and made a popping sound after a few more turns of the ratchet (it was definitely in the threads), so, to avoid stripping it, I stopped turning it and left the jack in it's place under the engine so that we can figure that issue out tomorrow (it was already 11pm).
So, while my exhaust ports are still plugged with socks, I have no intercooler piping or injectors, I can't attach the oil feed line even when I get the turbo on, I'm missing 3 lower oil pan bolts (though I used a small screwdriver to clear the RTV out of the hole so I can put them in when I find them), am having trouble lining up the upper pan's transmission bolts, have a weird motor mount bolt, and am altogether exhausted, but happy, it's getting there.
Questions:None.
Problems:Listed earlier, but all figure-out-able.
If anyone has any idea where I can get an NPT (female) to BSPT (male) converter somewhere nearby (hardware store?), please let me know, otherwise I'll get SPL to mail me one.
Anyway, I'll try again to post pics here in a minute, and maybe even take the time to upload pics from Day 1 and a few other pics from Day 2 that aren't in my gallery yet, then make a huge pic post (labled, of course) for reference.
My parents think I'm insane. My dad just figured out today that I was actually drilling my block, not my oil pan, he wasn't terribly excited, but remained silent, probably waiting to pass judgement until I try to start it. My brother says the car will never run properly again.
They may be right.
No matter, I'm having a damn good time.
