Progress.
Stripped and cleaned my cylinder head, did some mild clean up of the ports, cleaned and lapped the valves, reassembled with Volvo valve springs and Supermiata stem seals, and checked valve clearance. Only one intake valve was out of spec at 0.010", but I think I can swap shims from another valve that was on the tighter end and end up with happy clearances on both. https://cimg6.ibsrv.net/gimg/www.mia...232676ffa7.jpg My valves were pretty crusty, so I tried soaking them in Seafom overnight. Total fail, did hardly anything. https://cimg2.ibsrv.net/gimg/www.mia...27e4d361b8.jpg Berryman's Carb Dip yielded better results, but still required use of a drill and scotch brite pad. https://cimg4.ibsrv.net/gimg/www.mia...f0fda22c78.jpg I made an attempt at measuring my cylinder bores with snap gauges and a verniers, but I don't have a lot of faith in these numbers. https://cimg9.ibsrv.net/gimg/www.mia...25f65d448d.jpg And my parts horde continues to grow. https://cimg5.ibsrv.net/gimg/www.mia...d43a07f125.jpg In case you were wondering how the Volvo springs compare to BP6D and NA6 springs. https://cimg2.ibsrv.net/gimg/www.mia...507d517569.jpg |
Great thread! From rusty to a clean turbo is a heck of a lot of work!
Maybe I missed it, but I assume you're still driving on the 1.6 while the BP6D gets built? |

Maybe I missed it, but I assume you're still driving on the 1.6 while the BP6D gets built? The 1.6 is running pretty well at ~11 psi on the eBay T3. I drove it 250 miles the other weekend and it worked flawlessly. My plan is to leave it operable until around November, then swap everything in over the winter. I'll probably see if I can sell the turbo setup locally as a semi-complete package; manifold, turbo, exhaust, BOV, and DIYPNP. I'll have to do some more research to put a price on it. In other news, I've taken delivery of an EFR 6258 and BE pump. I've also ordered a Kraken low-mount with exhaust, MSPNP Pro, and an ATI damper. :burncash: Tasca is taking forever to ship my remaining gaskets and OEM 9:1 pistons - they've been on backorder for a month now. This is going to become the bottle-neck in my build progress before too long. I took a minute the other day to tally up how much I've spent, and forged pistons with machine work are starting to look like a small drop in the bucket like everyone says... |
Nice choice on the Kraken. Mines the original side mount and it's fantastic. The low mount looks even better.

Awesome plan!
How is the kitty doing? |

How is the kitty doing? I was rummaging through some old papers and found a dyno chart from 2004, when my car was stock but for a homemade intake and Borla exhaust. 105 hoss, boss. https://cimg5.ibsrv.net/gimg/www.mia...966fce452c.jpg And I still have this sticker on my firewall. Maybe I'll keep for the troll value. https://cimg0.ibsrv.net/gimg/www.mia...5e25a43cf6.jpg |
Definitely keep the sticker
|
You are going to love the full exhaust, everyone who has been around my car and seen it perform says it's the best sounding turbo miata they've ever heard. Something about the setup as a whole that screams, and still has a touch of rasp to it, and isn't too loud.
And I agree, that sticker is awesome. |

And I agree, that sticker is awesome. Recent progress: Ball honed the cylinders, painted the block, installed the crank with ARP main studs and ACL race bearings, and set ring gaps. Out of the box, my Sealed Power rings were at 0.020 for the top ring and 0.022 for the bottom, so I left them at that. https://cimg4.ibsrv.net/gimg/www.mia...52b337c08.jpeg https://cimg0.ibsrv.net/gimg/www.mia...ffc5174b0.jpeg There was a dump truck in the horse pasture across the road that looked to be smoking hilariously badly, but it turns out he was using a spreader with some weird white powdery stuff. No idea what that was for... https://cimg7.ibsrv.net/gimg/www.mia...8287d9d4e.jpeg |
Progress is looking fantastic!

off-brand. I forget what it was called, but I love the way it sounds and it's held up to corrosion better than the real Magnaflow that I have on my 323GTX. Would recommend. More progress. Not that I work that fast, just getting the thread up to date. Cylinder head is mounted up and torqued down with ARP studs. Boundary oil pump and Gates cast-impeller water pump are also installed. I dry fit the Hawley pump inlet and Qmax reroute. https://cimg2.ibsrv.net/gimg/www.mia...bcefb3649.jpeg https://cimg5.ibsrv.net/gimg/www.mia...9b76da074.jpeg I was pleasantly surprised how the QMax reroute actually makes the thermostat reasonably serviceable with engine still in the car. Access is from the side, rather than working between the head and the firewall. https://cimg3.ibsrv.net/gimg/www.mia...37a08891e.jpeg I'm leaning toward keeping the oil warmer, as I don't think helping oil get up to temp faster is a bad thing (especially on a mostly street car in a cold climate) and neither is even a token amount of cooling. Need to remember to order new formed hoses if I do decide to keep it. https://cimg6.ibsrv.net/gimg/www.mia...a08db9fc8.jpeg My amateur-hour port work. https://cimg3.ibsrv.net/gimg/www.mia...1b3812cd1.jpeg Remaining motor to-dos:
|
Get those formed lines on the oil cooler before the motor goes in. It really sucked to do mine after. I got an entire motor silicone kit on ebay for pretty cheap, it came with those two and everything else. My turbo coolant line feed comes from the TB and returns to the mixing manifold, I skip the front water neck location.
The one I got isn't around anymore, mine didn't come with clamps, and may have had a few more hoses. Looks kind of like this though: https://cimg2.ibsrv.net/gimg/www.mia...7f31b67d92.png |

Looks kind of like this though: https://cimg2.ibsrv.net/gimg/www.mia...7f31b67d92.png After more attempts than I'd like to admit, I've got my valve clearances all set. I ordered the wrong shims... twice. The first time because one of the shims was mislabeled as the wrong size, the second time because I added when I should have subtracted. Derp. https://cimg0.ibsrv.net/gimg/www.mia...d6c170f809.jpg I also rebuilt the VVT things. https://cimg7.ibsrv.net/gimg/www.mia...eef6c50103.jpg Installed my damper, which went easier than expected, though I'm not looking forward to ever having to take it off, I also found time to clean and paint the valve cover, intake manifold, and throttle body, as well as install a bunch of seals. Right now the valve cover, timing belt, and upper manifold are just resting in place to keep dust and debris out until I get a few other things sorted. https://cimg6.ibsrv.net/gimg/www.mia...9df813cbd5.jpg https://cimg4.ibsrv.net/gimg/www.mia...3329354e64.jpg I clearanced my main bearing support plate for the ARP mains as well. Had to remove more material than I expected, but there's ample room now. :fael: https://cimg5.ibsrv.net/gimg/www.mia...a44810e97b.jpg https://cimg8.ibsrv.net/gimg/www.mia...c018194095.jpg Shifting gears back the car itself, with it's still-running 1.6 T3 setup, I replaced my DIYPNP with a MSPNP-Pro and got that working. I'll clean up the wiring once I add everything I need for the BP6D swap. https://cimg3.ibsrv.net/gimg/www.mia...898e74b2f7.jpg I experienced some frustration getting it to run right, which turned out to be from an error I made when making my sequential wiring harness years ago. I think I'm just to leave it like this until the motor comes out shortly, then make a new harness. https://cimg1.ibsrv.net/gimg/www.mia...60607c7590.jpg |
I bought a t-shirt from a band in Australia that took two friggin' months to arrive, but included this rad holographic kitty sticker, so it was worth it.
https://cimg6.ibsrv.net/gimg/www.mia...46e1e3119.jpeg I went to upgrade my fuel pump with a DW200 and discovered this. Sadly not the first time I've found mouse nests in my car. There are too many nasty chemicals in the garage to let the cats in there so I'll need to more diligent about setting traps. https://cimg9.ibsrv.net/gimg/www.mia...aa5eb9eea9.jpg One of the culprits already expired. https://cimg7.ibsrv.net/gimg/www.mia...b29a28c90.jpeg Back to the fuel pump install. The kit supplied three identical o-rings but there's only room for one on the pump outlet. I put everything back together and went for a drive with no issues. Spares, I guess. https://cimg8.ibsrv.net/gimg/www.mia...cc98bf9ee.jpeg |
I got a shipping notice from Kraken, so it's full speed ahead in what spare time I've been able to manage.

Supposing I deleted my oil warmer, there'd be a barb fitting on the rear passenger side of the head. Would this be a bad idea for turbo water feed? Aside from finding a way to cleanly route the long hose hose, it seems fine to me, but I'm often a dummy. I have a strong desire to avoid tapping my water neck block off plate. (My revision in purple). https://cimg3.ibsrv.net/gimg/www.mia...f0f05be622.jpg |
My turbo water feed is from there and it goes through the oil cooler and TB first. I just ignored the water-neck location.
Did the sleeve that says DW200 come off your pump when you took it out of the package? Kind of hoping it did, since mine and a friend had the same thing happen, it seems best not to leave it on. And that mouse nest is probably the favorite mouse spot in a NA. I had the same thing, ruined all the phillips heads on the pump cover. Also had to splice in new wire for the sending unit as they had chewed off the insulation. |

My Kraken low mount hot parts were delivered a little while back. Worth the wait.
Test fitment of the manifold, turbo, and downpipe. https://cimg0.ibsrv.net/gimg/www.mia...e5695bb4e4.jpg That's one big muff. https://cimg9.ibsrv.net/gimg/www.mia...b17969e22e.jpg I spent some time carefully aligning my wastegate actuator like Savington demonstrates I was able to get everything perfectly lined up by slotting the holes in my wastegate mounting bracket a little bit. You can only move the wastegate can a little bit closer to the turbo centerline before it starts to bump up against the compressor housing (you can see this in the first pic in this post), but a little bit was all I needed. Now it moves like AidanJ's: https://cimg2.ibsrv.net/gimg/www.mia...c45ecff800.jpg Working on my water line routing, I may be able to reuse the heater hard line that goes behind the manifold. I like this idea because then I could retain shaped OEM-style heater hoses and avoid running a long 5/8" line around the drivers side of the engine bay. I cut the factory water pump inlet off the hardline and found it lines up very closely with my Hawley billet water pump inlet. If I carefully trim the hardline and tap the Hawley inlet for a barbed fitting, I should be able to just use a short length of hose as a coupler. I'll probably drill and tap another port in the big radiused part of the inlet for my turbo water outlet. https://cimg3.ibsrv.net/gimg/www.mia...a8fccee34b.jpg Clearance in the back is better than it looks in the pic. https://cimg5.ibsrv.net/gimg/www.mia...b3378a678a.jpg Clearance up front is good as well. https://cimg6.ibsrv.net/gimg/www.mia...e92eaa702f.jpg |

It snowed a couple inches, so I got out the neglected winter beater. I still love driving this thing; it's got oodles of grip and torque and the long, soft suspension is hard to upset on mid-corner bumps. I fixed a leaking vacuum hose to shut the CEL off. Now I should, like, register and inspect it or something... https://cimg1.ibsrv.net/gimg/www.mia...cd606f991.jpeg I took the dog for a slushy mountain run. https://cimg2.ibsrv.net/gimg/www.mia...2e452d055.jpeg Back to the car. Here's a close up of my FM flywheel after ~5000 turbo miles. There's some funny leopard spot oxidation patterns that I'm not sure how to interpret. I'll admit to some clutch dumps here and there, but I'm generally easy on clutches (the Forester has 203k on the original clutch). https://cimg3.ibsrv.net/gimg/www.mia...742077054.jpeg Worst spot on the pressure plate. https://cimg6.ibsrv.net/gimg/www.mia...7e4064d01.jpeg Lots of friction material left. https://cimg7.ibsrv.net/gimg/www.mia...5580d5d00.jpeg I slapped it together and sent it. https://cimg8.ibsrv.net/gimg/www.mia...57f9565ee.jpeg An just like the motor is back in the car. https://cimg9.ibsrv.net/gimg/www.mia...bbfb3a686.jpeg I'm loving the low mount setup. The downpipe has a much simpler path out of the bay and everything clears. If you look on the left side, you can see where I re-used my cut-down heater hard line. I welded a piece of angle iron to it for another mounting point. https://cimg0.ibsrv.net/gimg/www.mia...6a23dfa2d.jpeg Another morning trail run pic for good measure. https://cimg1.ibsrv.net/gimg/www.mia...9b5124b24.jpeg Right now I'm working on the remaining wiring changes and getting all the remaining minor items squared away. I'm hoping to do my first start this weekend. Hopefully the weather will be nice enough that I can can do a shake-down drive and get the engine broken in, at least naturally aspirated To do list:.
