The Background:

I built a 90 CSP Car, pretty competitive in the Detroit / Ohio region SCCA SOLO a few years back. A few states/jobs later I sold my car in the mix and picked up a 97 with a FMII-GT2560 in summer 17', in hindsight I should have been weary on buying a turbo yata with all supporting mods but a coolant reroute. Very shortly after purchase the reroute went in, but it didn't make it many miles. After I pulled the head piston #4 was confirmed melted .

why do you want to use a turbo from 1980?

That is the debacle, doubtful anybody wants to trade my FM Loggy stuffs for Tubi Stuffs

you could at least go GTX series or the new G series, with turbines designed within the last 10 year, not recycled from 1970.

Saturday Update:

Dropped the crank off for dynamic balancing, Pistons and bearing are off at Calico. Blocks out of the machine shop and ready for some more cleaning, paint, oil squirters, and the arp hardware.

Still need to order some gaskets in the near term if I would like to get the short block assembly done in December.


Was looking at my ATI Super Damper, it seemed that the trigger wheel could be giggled slightly clocking the location of the trigger. Im curious if anyone else has found this to be true. The Trigger wheel and damper, although concentric, does have some play between the diameters of damper to trigger wheel, and trigger wheel bolt hole to bolt. Wondering if this may have somehow aided to the failure.

Pistons are on the way back, pretty much nothing preventing me from throwing together the long block ~2weeks out. However, I didn't mark them for the little dimple which I believe needs to face towards the front of the block. Hopefully I will still be able to see it with the ceramic coating on. I didn't zero balance the pistons yet but that seems to be the last step preventing me from doindadirty.

Aren't the oil squirters typically deleted when moving to forged pistons?

IMHO there are only pros to having oil squirters in a high boost turbo application, I've already reinstalled mine.

IMHO there are only pros to having oil squirters in a high boost turbo application, I've already reinstalled mine.

Yeah, I don't really know enough to comment but I hope someone else chimes in. I've always read about folks deleting them!

Some Pistons have contact issues with the oil squirters. Some Pistons have problems with the oil squirters putting oil back into the oil control rings. It would depend on the design of the particular pistons you were planning to use.

Thanks for posting, just meandered through this thread, looks like the Wiesco Pistons / Oil Squirter combo is a no go.
Second guessing myself on keeping mine installed with the supertechs but I'm a data guy, going to do some more research hopefully some other turbocats drop in.

https://www.miataturbo.net/engine-pe...cussion-82895/

I have supertech and oil squirters in my built motor, but my motor was put together prior to that discussion thread. Nothing weird going on that I can tell at present but that doesn't really mean anything.

Thanks for posting this - something to consider in the 1 day I have between now and when I seal the oil pan. :s

Nice to see your build thread get started - good luck with the rest of the build!

It's a pretty easy check, bolt everything together and bar the engine over, look for interference. My '99 block with oil squirters, did not like the the Wiescos, so I blocked mine off. The interference was very obvious when I rotated the engine over, no pics unfortunately.

I'm glad I asked!
​​​​​​I just thought that you always delete them with forged Pistons because of the difference in thermal expansion. Didn't know it was essentially just about physical interference.

Why would you delete them because of thermal expansion?
My pistons were modified to clear the squirters but I chose to delete them. They are not necessary with the 2618 alloy, so I get more oil pump capacity for everywhere else. I think most folks agree that they are helpful with the supertech alloy and OEM alloys.

My thinking was that they either interfere physically or they're a hindrance to the pistons/rings getting to the right temperature relative to everything else. I.e. the pistons are a different material than stock and don't behave the same so adding oil there as cooling or to add more oil to the bores might have been counterproductive.

Thanks for the bolded above... I might be using that info soon.

https://cimg4.ibsrv.net/gimg/www.mia...49c3c3aa1.jpegWell, not much progress this weekend outside of cleaning the oil pan better than my dishes.
Hopeful the pistons get here tomorrow and so I can share some calico wins and document some of the zero balancing.

Another Buell guy! Subscribed. I have a 09 Ulysses and a 04 12R.

Im a fan of the buells. Ive owned a few bikes, mostly 4 bangers, but since I owned my XB12R...all my bikes will be twins. Currently on a 1125R, the xb9 is a friend i convinced to get one haha.

https://cimg5.ibsrv.net/gimg/www.mia...f793f3db5.jpegtime to cook some pies.
Less is more on the modification end for me, my dremel is handy but ill deal with .1g off on the rotating assembly. Had the block in the garage just waiting for it to get up to ambient temp.

Did you balance your rotaing assembly or was it that way out of the box


sub'd

I had the crank dynamically balanced, and the connecting rods balanced for matching the heavy & light ends.
The rest of the rotating assembly I weight matched as detailed in the table above.

CSP stickers on a turbo Miata. I like it. Ballsy.

Truthfully, my last miata (90 1.6 first pic in the thread) was TRUE CSP I just retained the magnets. This 97 tho, this one may violate some requirements of the class...

https://cimg7.ibsrv.net/gimg/www.mia...08f6a8d8b.jpegShort block is gewd and spinning ~6ft-lbs
Rings Gapped Top 0.017" had to file; Second 0.019" out the box.
Rod Clearance ~0.001"
Main Clearance just over 0.0015"
Thrust Bearing was just over 0.006"
piston to wall 0.0035”

Assembled with Lucas oil Assembly Lube and a drench of Lucas oil high zinc break in oil additive over the pistons.

Main Torque 25-45-65 ft-lbs
Rod Caps 20-40-60 ft-lbs
(In b4 tq + Angle guys, I kept track of the clocking when I snugged them up and did untorque all fasteners twice.)

I have not ordered any gaskets to seal this guy up, can't seem to find a good gasket "kit".

Overall assembly was pretty good, glad I called the quits on day 1 prior to putting the piston assemblies in on my overcheck I noticed I put a oil ring upside-down. If i would have done anything differently it would have been getting a circlip installation tool. Terrible assumption those would be no big deal to install without the proper equipment.

​​​​​​What does this indicate? How does one test this?

Just indicates that nothing is royally fubar, its one thing inspecting all the oil clearances but its pretty tell-tale if you messed up during final assembly.
I put the damper bolt in and spun it with an electronic torque wrench set to 6.1ft-lbs and it never dings and remains pretty uniform (no excessive stiction or binding) for the full 360deg. I also look on how the rings pull/push the oil around in the cylinders for uniformity and clocking in respect to where the ring gap land is supposed to be.

I believe anything sub 15ft-lbs on a miata assembly is pretty good? Im sure somebody has more input than I on this as this is my numero uno miata build.

https://cimg1.ibsrv.net/gimg/www.mia...301b6d48f.jpeg
Not much progress. Just waiting on the the OEM head gasket to ship.
Used loctite on the 8ft-lbs oil pickup tube was the only thing that varied, from what I could tell from OEM configurations. Didn’t see much instruction on torques from BE.

Put a question out to Fab9 about their tubi setup to pair with a 6758. I will have todo some more digging for the conclusion I believe I am seeking but the schedule 10 has me weary, would love to see some DFMEA with heat transients.

But I’m pretty sure my money’s set on Snagging a TSE kit due to some unrivaled success I’ve searched.

https://www.miataturbo.net/prefabbed...r-94048/page4/

Not much progress over the holidays. Went with the Artech long runner 40mm EWG manifold pictured above, likely the last one to leave his facility. Will have to modify either the T25 housing to V-band or the EWG dump as I do not see a T25 flange with EWG setup for a EFR 6758. Will most likely just grab a V Band clamp and another 40mm flat stock SS / Alloy600 and run a EGT sensor there so I could mount the T25 internally gated 6758. I have deducted more pros at my desired boost pressure with the Internally gated vs. ex.

Piecing together a fuel system:
ID1000s
Fuel lab reg
Radium fuel rail
Walbro 450

This setup is looking pretty potent referencing some other 6758 builds on here.
Should likely update my HP goals for this season, I would like to run on 93 only. Depending on how smooth this season goes next year it would be cool to upgrade to a e85 setup with a MS3.

Fuel Rail, regulator, and the associated lines and fittings are here. Also this pretty thang hit the mail.
Guess its time to do the taxes and order that 6758, Abe is the man and swapped the T25 out for the Vband so i could run the .85 this should pair nicely with the CNC head. https://cimg5.ibsrv.net/gimg/www.mia...d43494e322.jpg

Been a few, but spring is here.

K-miata BP to BMW kit and all associated goodies are here, thanks OOjk3a.
EWG headed here as well, thanks Viperormiata
Sold my 10" 6ul to snag some x11"
Dropped the rear subframe for the weld in V8 roadster kit when it gets here in two weeks.
Motors all together, getting some parts lists together for the water/oil feed lines for the EFR have a TSE Oil feed adaptor on the way. Still need a sandwich plate(anybody got one),I want to retain the heater core going to have todo that whole flip/cut/weld in bung thingy the water inlet flange.

Side note Dave over at K-miata is the real deal, more helpful than any aftermarket supplier Ive dealt with.

I think your damper is from prior to the December date that Fab9 mentioned, but worth verifying while you still have slightly easier access to the damper.

https://www.miataturbo.net/engine-pe...dampers-96402/

That's news that yours from early 2017 is bad. The teeth to notch are out of alignment? Have a pic?

Good luck man!

Lawd hav merci.
I read the thread at work and did not see the "after* 12/17" until now.
Ready for full send.

Put .001 miles on the motor yesterday taking it from the kitchen to the garage.
Slapped that 5 speed, with lots of alignment overcheck to the pilot bearing, only to confirm I goofed. You need to reuse the Miata flex plate/gasket thing to hold the dipstick. Quite an oversight, glad Tonymontana had a pic detailing this, and the two bolt starter connection, this had me very confused glad I was able to reference his very detailed thread.
Stage 2 Kmiata half shaft /axle kit showed up just waiting on the V8 roadster weld in brackets and brace.

Subscribed, glad to see this kit getting put to good use (again)!

Well. The motros in but on hold.
Differential is in and the rear ends back together.

Turbo - somewhere being built
S2 Throttle Body - NotFab on Backorder or something for a month+
Blackbirdfab Spoiler - few weeks out.
TSE oil feed adaptor - shipped

Fuel: Still need to decide on a injector size. Likely goin to be ID1700, scrub the complexity with flex fuel wiring/sensors there's E85 all around me.


Guess its time for whatever wiring / plumbing in the interim.

https://cimg2.ibsrv.net/gimg/www.mia...9d3ce59fd7.jpg

7 Week lead time on the turbo.....anybody else know where I can source a 6758 EWG V Band faster than that.
Yet again the S2 Throttle Body has been on order for 4 weeks now...
First AutoX of the season the 22nd, what a pipe dream.

https://cimg6.ibsrv.net/gimg/www.mia...8b14be4b46.jpg


Started the fuel rail / regulator / line install. Going for the semi cleanish look. Keep all the hoses towards the back of the bay. Need a few more 90s for a cleanish install. Skeptical on the Hard line ANs, Jegs says 55PSI max. That may be an issue, would definitely limit me to the ID1700s to keep rail pressure low....which would then make the Toyota COP the limiting factor....where does it end.

Hood vents are in and look great. About ready to start drilling the brace for the BMW trans mount, going to need to overcheck the alignment and angle again something feels off about the throw from neutral to fifth, its about half as long as neutral to first but maybe thats normal.
Then ill be back there on hold again.
Fabuoulso9 still has that prestige world wide backorder on the S2 throttle bodys.
Turbo should be here in a week or so. Yay.
Ive been slacking on a injector order ID1700s are a chunk...been waiting to see if one pops up in the FS threads.

https://cimg7.ibsrv.net/gimg/www.mia...c2d28b4f29.jpg

more aero nonsense. Install was pretty straightforward, definitely pay attention to the torquing order. Would have loved to do a A2B comparison when the car was running ran out of parts to install and didn't want to lose a weekend.
Turbo should be here this week.....finally.
No word on the fabulous S2 TB, ordered in February, sad panda.
https://cimg3.ibsrv.net/gimg/www.mia...7172548709.jpg

I have no idea whats up with Borg Warner but ive been waiting on the turbo since March, keep getting some "production issues" generic email.
Much disappoint, at least the throttle body is here, cut the throttle body warmer lines off because they did not clear the alternator bracket.

Settled on the ID1300, Wal450 for Fuel needs.

looks good man, sucks waiting on backordered parts though

Sweet build. Subbbbbd

Well, good news the turbo arrived. It says on the nameplate its a .64AR-WG so I guess borg just used a super core off a one they had in stock and then slapped the .85 turbine housing on it.
of all the tools I have access to at work we do not have a Mandrel, and the amount of hours I think it will take me in pie cuts means Im leaning towards just dropping it off at a fab shop for a downpipe.

Likely slap on a straight pipe for the break in miles though.

Did a quick crank and let it run for a few seconds on the old gas. Looks like theres a oil leak from the oil filter/oilwarmer assembly which will need to be addressed. Outside of that looking for some tangible data to determine how far downstream I can safely run the external waste gate, it won't fit as planned under the turbo.

Any takers on a base map for a 8.6:1; E85; 1300cc injector I can do some break in miles on?!?!

Car build is progressing nicely!

sweet build man. How come no obligatory comments about the girl in post #1? "Did she come with the car?" "Did you pick her up in the F/S forum?" "Which is faster?"

Thanks, there is actually two!
the XB9R is my friends,
I have the 11125R ^_^

Few updates.
Really slacking on closing this out.


Went to put in the fuel pump but looks like the "kit" had the wrong grommet and didn't include the pigtail so thats on hold.
https://cimg7.ibsrv.net/gimg/www.mia...31e3a1034.jpeg

Did the plumbing for the turbo oil/water lines, its slightly tighter than I would want it to be but with the removal of this bracket I do not think I will have any rubbing issues. Opened up the -10AN Oil Drain line fitting from ~.50" to .555" per the lessons learned threads Im reading. Had to retap the pan for a 5/8" Push lock to 1/2" NPT, should be all set here.

Going to do break in miles with the manifold wastage port blocked off, and no intercooler piping and just a 3" Dump out the hood that took me a few mins to make, than start tapering on the boost after alls sorted out and pair it with my 3" Full exhaust. (in b4 hood dump flame) Not going to make the full downpipe / wastegate exhaust now as I will be doing the brake booster delete sometime after she's a runner.

https://cimg2.ibsrv.net/gimg/www.mia...db6edd7710.jpg

Small update put all the fluids in and started it up.
Sounds wild, timing is way off from when I swapped the CAS over to the CNC head, will need to do some adjustments it looked at >20 deg at ~idle. Coolant inlet hose has a non -favorable bend, and the S2 throttle body needs some attention for the spring tension mod. Outside of that could be on the ground this weekend on some 185 14x6" wheels (sold off my 15x8 wide opens and 15x10 6ul if anyone is selling ). Planned to drive it no boost piping on 93 for a hundred miles or so than give it the beans on e85.

https://cimg6.ibsrv.net/gimg/www.mia...51ddd341c5.jpg
~50 or so miles in, one of my AN water lines I must have not tightened enough and that went pop but outside of my coolant hose/throttle body bind and a speedo/odo solution smooth sailing. Time to get it back up in the air for some boost piping and a downpipes solution to mate this ARtech mani to my 3". Should throw a flex pipe in there as well.

Running VE analyze on one of the first higher load higher rpm decels yielded some brotastic flames bro.

So close but so far.
Running the EWG below the turbo is too sketchy / doesn't really fit so I'm making a spacer for it and then the downpipe.

Some other goodies showed up though, was waiting on a set of wheels so I could run the intercooling piping for clearance.
x10 with 275 A6 shown on virgin fenders. I have autoknex aero fenders for the front and some ebay flare for the rear but maybe ill just try to sneak 245s on rolled fenders for now and ditch the girth.

Looks ready to roll-ish
Put a 15psi yellow spring in the EWG, plumbed everything else. Currently making the downpipe so as it sits is really only for internet hero pulls.
Running the "tuner" map of MS DIY paired with VE analyze but if you're an e-tuner with availability let me know. :skid: (Vlad, take my money)

PO had a single diagonal Harddog in there, could have been a knockoff even but I came to find out there were no back plates, so found a local deal on this zerekfab, looks pretty good cant say much for the fitment yet.


Yes, I know, I need a mandrel bender and kapton tape.
