Round 2: Wannabe turbo NB6C

![Default](https://www.miataturbo.net/images/icons/icon1.gif)
Got some work done today that was turbo related. After lots of measuring to double check clearance in the bay I ended up with the below

Evo 10 turbo with a 20g compressor wheel from my old evo.

Trying to keep the 2 scrolls isolated up to the wastegate valve face so I split some of the 1.25 Sch10 down the middle and added a divider wall
Will finish that on the weekend

yeah i have about half an inch of clearance. It's not fully welded to the flange so i can take the runners down a bit to get some more.
I got the bearings, pistons and head gasket yesterday. Picking up the Manley rods and borrowing a ring filer tomorrow. I'm headed to orlando for a week on saturday so I need to order up a few things and get them sent to the hotel so I can button up the long block and get it in the car.

Flying up to Tampa tomorrow and driving over to Orlando so I ordered all the gaskets, gtx pcv valve and trigger wheel for the ATI damper from Fab9
Also kinda mocked the manifold in place on the 1.6 to check on the frame rail clearance

Fitting that big *** Tial 38mm wastegate down the back there is going to be....challenging

Finished welding up the manifold, got some 1" plate from a friend to drill the flange bolt pattern into since my brother still has the head.

Got some 1/2" plate cut out for the turbine outlet flange. My hole saw has seen better days so I need to pick up another 2" and 2.5" to finish it.

Cleaned, oil squirters blocked and King bearings in place. Main bearing clearances ended up being 1 & 3 - 0.0020 where as 2, 4 & 5 were 0.0015. The rods all came between the 0.0015 & 0.0020 plastigauge marks so on the loose end of OEM

Head on

I'll get the oil pump back from my brother tomorrow so I can button up the long block. I'll be pulling the tumbler plate crap out of the VTCS? intake manifold I have and blocking off the holes left.
My 6 speed gets here end of June..I am not sure if I should bother installing the new motor with the current 5 speed and swap out when it breaks or just wait.

Found the differences between 1.6 motor brackets and the 1.8VVT block. I have some 1/8" stainless plate that I'll use to adapt them. The other side lines up 2 out 3 bolts.
Thursday I'll pull all the rest of the **** out of the bay and degrease the crap out of it. Will be respraying it with real paint.

Completed today:
TIming belt and water pump on and motor timed
Modified 1.6 engine brackets to work
Marked windage tray to mod for ARP main stud clearance
Drilled hole on correct side of oil pan for turbo drain
Welded up oil pan baffle
![](https://www.miataturbo.net/attachments/build-threads-57/173099-round-2-wannabe-turbo-nb6c-img-20160602-wa0025_zpsqqdjq9uc.jpeg?dateline=1464911261)
Did some oil line mock up for the turbo feed. Hopefully this location pans out

Oil cooler & filter relocation stuff. Also added the 4an adapter to feed the oil pressure gauge
In related news the container with a bunch of **** has arrived at the port. Should get it delivered by monday.
Hard top
NB2 front bumper, headlights & tail lights
6 speed transmission
Clear fender indicators
Autoexe front and rear under braces
Mazdaspeed front 3 point strut brace
Origin Labs wing
Should have the skirts, bumper and hard top painted for next weekend. Cant wait to get the 1.8 in with the 6 speed so I can get to sorting out the down pipe.

Lower coolant manifold modified. Reclocked the outlet to point down a few degress, welded the front coolant port shut and added a 6AN bung for the turbo. Notice the oil drain is on the right side now

Tons of space for the universal ac unit
I need to add the VVT solenoid connector and double check all the inputs on the haltech. I also ordered up a few things to do the down pipe and wastegate. It's looking like I should be able to plumb the wastegate back into the exhaust which is nice.

As you can see I had to add some clearance for the compressor housing

Got a **** ton done but it doesn't look that way. Finished the downpipe and wastegate stuff and wired up the VVT to the haltech.
That bastard mazdaspeed brace gets in the way of everything.
To do list
Intake
Turbo plumbing
Random vacuum hose stuff
Brake booster line
Fluids
Waterpump pulley and belts
Upload vvt base map
I'll do the ac stuff later on
