Gotta love a stubborn stud, the last one I tried to take out almost broke my toe when the housing decided to yeet itself from the vice. Luckily it hit me on the crooked one, that one is already pre-hardened

Also ditto w00 for the progress on this!

Really looking forward to how the K24 performs. The bigger turbine vs. a TD04 has always been interesting to me.

it's not as bad as it looks, it's gonna ride for now. most of the 13c's and other td04's I've seen of late look fairly similar as well.

modified the manifold and turbine housing for this part


also did a little opening of the collector area (didn't full on match the k24, but it necks down fairly fast anyway so it'll be fine), nothing special or big so no pics there.

clocked by eyeball (and it looks good on the car too, so I'm gonna leave the positioning and make any needed minor adjustments with the chra, but it looks about perfect too)


bolted up briefly to check things


discovered the lower coolant fitting is the same size as the 13c coolant lines, this will make things a bit easier to connect the water lines (Although that top one is special, I think I can make it work), also laid out how the gate is going to attach up


cut up another volvo part for sacrificial alu blocks for a second attachment point on the gate bracket.

haters will say that wasn't a volvo part...


not pictured, oil feed is off, oil cooler is floating loose. today's gonna be a short day at work, so I'm gonna probably wrap it up in the shop, try and get the GTO test driven to make sure it's as good as I can get it (friggin stock ecus, been manipulating like 3 numbers to get a nice idle to reverse to drive to neutral to drive to reverse to drive to... transition without setting the idle so high that the car drives off on it's own or tries to drive through the brakes), might cut the grass this morning and then start working on the car again. I'm waiting on a fair amount of little fitting bits and bobs for the turbo install. things seem to be going well though, hopefully this weekend I can get the exhaust wrapped up, all of the fuel system wiring done, intercooler mounted, and be left with some relatively benign stuff coming out of sunday (maybe just bolting the turbo up, that sort of thing) so I have time to get other things sorted out (alignment, charge piping, maybe window tint..ooo.. all of those places are within a block or two from each other).

on a side note-is there anything special about headliner material?

not much progress to speak of yesterday, going to work on exhaust more than likely today, ran into some welding (talent) issues last night with the alu block for the wastegate, but that was later in the evening.. going to see if I can get it cleaned up and working better, and/or call in a stunt double. not looking for beautiful, but it wasn't wanting to stick at all. not sure if there's an issue with the shielding gas, or if the nastiness on the compressor cover is even nastier than I was thinking.

did get the exhaust flange worked out though, the GTO is gone (guy said it drove good, best it's ever driven), but they did leave me with a belaire to basically do the same thing with. it'll get the gto tuneup and a dyno verification/cleanup... buuut that won't be today and probably won't be tomorrow. (they're not in any rush atm)

got greg to hook it up on the compressor cover (didn't want to be paid, no worries, turned around and bought $85 worth of vband/flex/o2 bung, and he's gonna be doing the intercooler piping)

exhaust progress is going along ok, it being football season, saturdays are tough on the ol attention span. downpipe is basically mocked up and tacked up though, if I escape the house here in a minute I'll pull it off, weld it up, see what moved, and progress rearwards. I have enough 'stuff' to plumb the oil lines on the turbo and crank the car if I want, I will probably do that ahead of the ms install, if for no other reason than to check for leaks.

pics to come later, but I'm fairly pleased with the downpipe thus far.

mockup pics. gonna have to go back over it with the tig, the mig skillz just weren't what they needed to be.











I think it turned out decent. gotta figure out where I want the o2 sensor bung. I stopped just aft of the cat last night (so flex, vband, cat, and angle up to resonator before the over the axle piece, then out the back thru a muffler), still shooting to be done with it today and move on to wiring and probably getting the turbo installed. depends on outside factors (of which there are many)

Looks good in terms of placement. Is that just aluminized steel though? SS would hold up much better.

it's not really a big problem down here, I have parts laying around that are a decade old. Stainless welds up a lot better (for me) usually, but it's not a big deal here.

figured out where the big hangup was on the v8 car's old exhaust:


3in resonator necks down to 1.75 or so. it didn't collapse, that's how it was made... :-/

anyway, so after finding that, I opted not to use it on the black wagon (was gonna put 2 resonators on there along with the rear muffler and cat, but eh. if it needs more to tone it down, I have space for that)

middle piece of the exhaust (cat and resonator-not pictured)


resonator


over the axle.. this got a little gappy on me, and it turns out, not all of the bends were a very consistent diameter. not likely to cause problems with the power level I'm targeting, but something to keep in mind in the future.


rough welded up, will go back over it this evening and make sure it's good to go.


did get a lot of time side-tracked this weekend, but I still more or less ended up where I wanted to be. going to strive to have it to a point tonight where I could potentially crank it up.

downpipe is just about finished, going over the midpipe section shouldn't take too long, then the rear piece (over the axle part) will be somewhere between the mid pipe and downpipe in terms of time to finish..

so a quick state-of-the-union (waiting on dinner down at the house):

turbo install:
-drill and tap bolt holes for gate
-'adjust' lower coolant line
-'adjust' upper coolant line
-install block fitting, re-install oil filter adapter
- bolt up turbski

install exhaust:
-finish welding errrthang
-pick spot for o2, weld that on
-toss it all up in there

hook up coolant lines
hook up/tighten oil lines (tried to pop the cooler lines off the sandwitch adapter, but they didn't want to cooperate, one is loose and oozing)
add water and oil

prime and flush the feed line (no run, just crank)
wire up the pump in the back, hook up filler lines, tuck wiring for pump & amp.
put gas in 'er
bolt up rear wheels after leak-checking (key cycle prime and/or jumping the relay)
adjust driver's side strut mount (changed position on passenger side, need to at least get it in the ballpark lol)
install longer studs
cobble together enough intercooler piping to get the car to greg's shop for the new piping (well, new hot side pipe and modified cold side pipe), and the alignment shop around the corner.

then it's back and installing the ms as well as the new stereo, and figuring out what's involved with the headliner (at least to take it down in one piece cause it be saggin' and you know what happens next).

fun times. gonna try and sneak it onto the dyno to get the tune decent, but I reckon we'll see how that pans out.

I hurt this morning. up college late, trying to hit targets. hit most of em (despite the 2x rule and 3x rule being in full effect.. normal tasks take twice as long, and nominal tasks take 3x)

didn't get to the wiring part, but I'll make time for that this morning whilst catching meetings from the shop.
anyway, pics

exhaust


it'll get hit up with some 2000 degree vht paint

the turbo that took friggin' 2 hours to set up.. every... single... little... thing...


one of the faster mods it required


installed!


At that point I should have stopped, but.. I couldn't help myself.
o2 sensor location


aannd welded up and bolted up


view from the back forward. thankfully the exhaust didn't move much during welding. rear muffler sits a touch higher and the center piece was a bit of a tug to get to the vband, (which may be why the rear muffler is a little higher), but all in all it's livable I think. Hopefully today there will be sound bites of it running at some point.

Is that oxygen sensor location going to be making the sensor point down? It kind of looks like it from here and that usually isn't great for the sensor. Otherwise, can't wait!

yea a little bit. not too worried, if it eats sensors I'll find somewhere else to put it

ran out of gas tonight after burning most of it last night. got the return fitting, discovered that my genius plan was a 45 degree fitting away from perfection...so the return still isn't plumbed. no worries, that will allow me to slow down just a little and work on everything else whilst waiting for the amazonian. (read: gonna go ahead and do the wiring, install the ms and injectors, and try and sort out all the other things like the oil cooler relocation that I didn't know I had to do lol)

so yeah, from the list:
turbo install:
-drill and tap bolt holes for gate
-'adjust' lower coolant line
-'adjust' upper coolant line
-install block fitting, re-install oil filter adapter
- bolt up turbski

install exhaust:
-finish welding errrthang
-pick spot for o2, weld that on
-toss it all up in there

those items are "done-ish", the return line isn't hooked up yet and I gotta flush the feed line still, so it's not tightened down yet. water lines should be a quick thing tomorrow, already eyeballed them and that's not too big a deal.

the oil cooler movement though, that one is gonna be a little more interesting. got a couple ideas, probably my favorite is sandwiching it between the condenser and rad for now, under the intercooler (if that's even possible), or maybe moving it over a little. it's just enough in the way to be completely obnoxious. I'm also interested in retaining the charcoal canister, so that kinda crowds things over there as well.
so that, the fuel pump wiring and tank plumbing (what's left, which isn't much) are high on the list for tomorrow, would be nice to have it sitting on the ground at some point as well so I can get an idea of how to adjust things. Oh yeah, and the wheel studs. that'll be probably after ride height is adjusted. depending on how long all of that takes, I'll move forward on the list of things to do.

WELL. today was a day that feels like it was wasted (it wasn't, but it feels like it).
got the injectors swapped, jumped the resistor pack, hopefully figured out a way forward for the oil cooler, tbd. Wired up everything else 'pertinent', promptly blew a fuse with the fuel pump (suspect bad relay, but we'll see), jumped the relay (no more blown fuses), discovered leak at the sending unit.

dammit.

it *looked* like it was spraying out of the bulkhead fitting coming off the pump.. looked a *whole lot* like that was where the fuel was coming from...

so I dropped the tank a bit, popped the ring off, and took a look, replaced the clamp on the inside, hooked everything back up (because idiot), aaaaaand still leaking. this time I looked closer and just let it leak for a minute, and the GD hardline for the return hose was spraying up on the fitting for the feed.

dropped everything again, scrounged up another AN bulkhead fitting, found a 90 and a spare -6 or -4 or whatever the hell it was fitting and put the hose on that... problem solved.

this sounds like it should have taken like..30 minutes. in reality, it took a leisurely 6 hours. Glad I went ahead and baked in some extra time.

Oil system primed up and looks good thus far, cooling system shouldn't be a big deal (Famous last words), and running of a couple vacuum lines/wires/etc for the MS hookup, as well as wheel stud install and some suspension adjustments. Gonna be a busy evening tomorrow. I have a couple pics, but.. nothing really all that interesting.

oil return is hooked up, went nice and smooth (So somethings gonna leak :-/ ).
pulled the brakes and rotors off, popped the passenger hub off, popped the old studs out and used them to pop the tone ring off. stopped to cook dinner, after I get done down here, gonna head back up, work on resizing the holes (have a drill bit and a reamer, going to set up something repeatable and work with whichever one seems to do best), pop the new studs in, probably have to go get new lug nuts (whoops), and yep. once that's done (or done to the point I have to find something else to do) I'll switch gears and start working on doing the ms install.. which shouldn't take long, put the cooling system back together (also shouldn't take long), rework the bracket for the oil cooler or at least find a temporary hole for it, and bodge together some kind of intercooler piping to get me over to greg's tomorrow.

"GD hardline"?

Which one was leaking on you? One of the fittings you had added?

in that picture, it would be the very top coated line above the AN fitting (factory return line). it had a rust bubble on top in the inside radius of the bend going to the hat, and that's where it cracked. it sprayed directly up on the AN fitting for the feed, which confused me for a bit because it looked like the fuel was coming from that.

Car runs, front suspension is adjusted (mostly), will probably raise the rear a little, but I'll make that call after I drive it a little. later today is intercooler piping time, I'll try and get the video posted as well but it's just a basic mk.1 short idle video. Sounds decent, quiet, so... here's hoping.
