Default Turbo Smurfette - Build in progress (slow)

Hello all, I've been convinced to building a 1.8L as opposed to my prior 1.6L plans.

I was able to score a block and crank locally, and I have a head coming in from Hobbs.

A buddy was able to pick up an EFR6258 locally for me and I am now trying to get the rest of the bottom end bits figured out and ordered.

I need to sell a set of brand new in box FM Wiseco 1.6L turbo pistons, I wish I could just trade them for the 1.8L pistons, but I guess i'll just be taking a loss on this one. Such is life.

So...parts I have (or have purchased and am just waiting for arrival):
95 1.8L bare block and crank
99 Head/VICS Intake Manifold
MSPNP Gen1
Innovate MTX-L Wideband

Parts to order:
ARTech exhaust manifold/downpipe
Pistons of some variety (leaning toward Supertech)
Eagle/Manley rods
FM 'rebuild kit' for gaskets and bearings
FM 1.8 swap kit
Oil Pan/pickup
Boundary Engineering Oil Pump (what advantage is there to run higher oil pressure?)
Water Pump
Intercooler bits
Exhaust bits
Injectors
Fuel Pump
Clutch

This will be a relatively slow build but I'll update as frequently as possible. Listing out what I'm lacking makes the task seem all the more daunting.

Current issues I need to do more research on:
-Running VICS and EBC from MSPNP that only has one output (or just ditch VICS?)
-Properly installing the wideband, splicing existing wires since I don't have the center plug for MSPNP Gen1

Today:

IAT bung was welded to an intake
MSPNP is operational, car is on speed density
Wideband is installed physically, but not yet wired
Superfluous wiring from a shitty non-working alarm has been removed from under the dash

To do:
Still need to raise the car up a bit
Learn the ins and outs of Megasquirt and tuning
Parts aquisition

You will be very happy with the EFR.

Will snap a shot of the IAT installed by throttle body.

Wired the O2 sensor in but am having very slight variation in gauge reading and what is read in TunerStudio. I don't have the 'Calibrate AFR' feature to set the voltage for the MTX-L wideband, so I'm just using the Innovate LC-1 Default 0-5V 0.5-1.5 Lambda.

Tinkered with the After Start Enrichment table and the cranking spark advance and now it fires up fine.

I'm uncertain what to do now other than VE Analyzer live for some of my commute time. I've been trying to read up before I really start to blow things up. I have a pretty bad deadspot at partial throttle where the AFR fluctuates between ~14-17

Does anyone have suggestions for the Exhaust Gas Settings?
EGO Sensor Type: Wide Band
EGO Switch Point(V) 2.489
Ignition Events: 74
Controller Step Size: 1%
Controller Authority: 5%
Active above coolant temp: 160F
Active above RPM: 1400
EGO correction step counter: mSec

I want to learn to tune a stock motor before I really start building the turbo motor. But am just getting familiar with Datalogging and what certain values in the VE tables mean. I'm still uncertain what to change and why (i.e. when its lean in a certain spot, do you just increase the values of the highlighted cells?)

Car bogs under partial throttle accel, and AFR seems erratic (but is fine when idle, cruising, light load). The areas where the car feels like it's bucking, the VE Analyzer flashes with an "Accel Filter"

How does one adjust load dependent fueling?

My brake rotor cracked on the way home. I think the caliper got stuck and the pad just dragged for a while on highway. I've ordered new front calipers and will be replacing the brakes soon.

I am going to change the ground on the o2 sensor, hopefully this will keep it from sweeping erratically.

Trying to strike a deal with Hobbs on his 1.8 block. Ordered some conversion parts from Flyin' Miata and some gaskets.

Sent payment to Abe for an EFR top mount manifold and downpipe.

Things on the horizon:
Raise the car + Outer Tie Rods + Alignment
Clutch/flywheel selection
Fuel Pump
Injectors
Intercooler sizing/piping

Updated list of purchased parts:

'99 Motor
- 99 Block and crank
- Wiesco 8.5:1
- Scat rods with ARP hardware
- ACL Race bearings - Main/Rod/Thrust
- ARP Main Studs
- 1.8 Crank scraper

'99 Head
-Supertech +1mm valves
-stock valvetrain otherwise

Artech Fab turbo manifold/downpipe for EFR

BW EFR6258

Toyota COPS



Stuff installed in car:
Innovate MTX-L
MSPNP1


I still have a ton to learn, but am already fearful of potential limitations (still beyond my knowledge) of the MS1. It seems there were several things addressed with the newer generation which might be advantageous, but perhaps I haven't reached those limits yet. So while I'm sticking with the MS1, later down the line when I become more familiar/comfortable with the basics of tuning...an upgrade will be on the horizon. But for now I'm still trying to understand all there is for tuning a stock motor.


Things I need to get:
Harmonic damper
BE Oil Pump (stock pressure?)
Injectors
Fuel Pump
Clutch
Intercooler
catback exhaust
99-00 oil pan baffle

Two months later and little progress, just purchasing and researching.

Ordered coolant lines for the turbo and a 3" exhaust.

Motor should be coming with the hall sensor bits but it would be easier to run the MS1 with the CAS.

I am debating biting the bullet and just getting Braineack's MS3x unit and running some extra wires for sequential injection and the 99 sensors.

hmm.....

Nice progress. From what I understand the MS1 is adequate but will never drive like stock due to certain limitations. Upgrading would probably help a lot once you have a built turbo engine in the car.

This build thread would be better with more pictures.

Your build set looks pretty epic. But lack of pictures is boring as i don't really care to read about pretty things, just look at them.

Your engine build looks almost the same as mine. After seeing Dems valve float i decided to get some springs though. lol
Get the BE street pump if it's going to be mostly a street car. I just went with the stock pressure (60psi no shims). I'm sure that's more than enough.

You're doing things right though. Keep it up with the tuning, the more you do, and tinker with the more you'll learn. Just watch the AFR's. It helps to have a friend drive the car. That's what i did initially.

Woops, forgot to update for a while.

Picked up a 6 speed and lightweight clutch/flywheel kit.

Obtained a squaretop intake manifold

I got all the turbo manifold and exhaust stuff from Abe at Artech, just waiting on the inconel locking hardware. Using AN6 oil feed line per Borg Warners recommendations for length and cold climate usage of turbo. I have obtained a Begi #3 intercooler and have the flyin miata silicone charge pipes, but will likely try to get the hot side fabricated out of some metal to help shed some heat pre-intercooler.

It looks like until I can get an MS3 unit built for sequential injection/spark using the 36-1 trigger wheel and BP4W cam position sensor, I will just be using the old NA CAS for batch.

Things on the agenda:
Get a waterpump kit
Find an oil pan/baffle and weld a bung for return line
Motor assembly


manifold came back from swaintech today

Looking great man, get us some more pictures of the car!. Sounds like you have serious plans for this car.

picture was taken in between progress. as of today the motor has:




New head gasket
ARP head studs
scat rods
wiseco 8.5:1 pistons
Head was installed
Water pump installed
Boundary Engineering Oil Pump installed
Timing belt/pulleys

Looks great. Don't forget that FM ninja tool wedged in those cam gears

Haha, I just placed the valve cover on for the photo.

I love the way the motor looks with the belts and pulleys exposed. I don't have the center/lower covers but I'll have to source them to set timing. Probably safer to have them anyways but eh.

Trying to figure out how I want to proceed on the fuel rail. I need to find spacers and bolts to mount them, and obtain a 1.8L FPR.
