Turbo Smurfette - RETIRED - Built VVT with EFR6758 and Flex Fuel
After 7 years, lot's of fun and learning, it's time to move on and learn something else. This car has been retired and parted out. Everything in this thread is a snapshot of it's glory.
I've recovered over $32,000 in selling parts to put towards other projects including restoring an old Datsun. RIP Smurfette...you've been good to me https://cimg4.ibsrv.net/gimg/www.mia...ef811641a9.jpg 2019 Setup: VVT HEAD Supertech +1mm O/S Intake and Exhaust Valves Supertech Double Valve Springs - Heavy Port and polish Tomei VVT Cams Shim under bucket conversion Square Top intake manifold Skunk2 64mm Throttle Body Coolant reroute BLOCK Supertech 8.6:1 Pistons 84mm Bore Eagle forged rods ACL Race Bearing kit Boundary Engineering oil pump +1 shim SADFab D585 LS Coil Brackets Injector Dynamics ID1300cc injectors FuelLab fuel pressure regulator Deatschwerks DW300 Fuel Pump Cast Impeller water pump Fluidampr Crank Pulley + FM trigger wheel TURBO Borg Warner EFR6758 0.8A/R Twin Scroll Borg Warner 90° Outlet Compressor Cover Ridge Fabrication Top Mount Ram Horn twin scroll manifold ARTech Turboback Exhaust with MT.net approved muffler Custom Bell Engineering intercooler DRIVE NB1 6 Speed OSGiken + 3.63 Final Drive Twin Disk Clutch with Carbon/Kevlar friction material HANDLING NB Manual Steering Rack *Rare OEM* Trackspeed 11.75" Wilwood front brakes M-tuned adapter Sport Brake rear Xida Gen 2 800f/500r RacingBeat 1.125" front sway bar 14mm rear sway V8Roadsters front subframe V8Roadsters tubular control arms Singulär Backing Plates/Brake ducts Bauer Extended Lower Ball Joints ELECTRONICS Brain Built MS3x, knock module, full sequential Flex Fuel Sensor Innovate ECF-1 Wideband and Ethanol gauge Revlimiter Warbird gauges STRI DSD SLMII - Boost, EGT, Oil Press, Oil Temp OTHER BlackbirdFabWorks GT3 roll bar Hard Dog Door Bars Lotus Elise Sport Seats with flipside brackets 15x9 6UL with 245/40r15 Hankook RS4 NA8 Gas Tank with complete -6AN Line conversion Singulär Hood Vents Soft top removed Quilted door panels and parcel shelf (DIY; built not bought) KGWorks black instrument cluster panel NB1 Fog Bezels in NA bumper for Brake Ducting 2018 Setup: Old Stuff (Blown up): 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 a buddy was able to pick up an EFR6258 locally for me (from Soviet) 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 kbai |

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 https://www.miataturbo.net/attachmen...w-img_9683-jpg |
in for pix of IAT bung
|
Im interested in opinions on this also.

more pics of the smurf!

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 https://www.miataturbo.net/attachmen...11883700_n-jpg |
Looking great man, get us some more pictures of the car!. Sounds like you have serious plans for this car.

ohh man that mani is pretty

picture was taken in between progress. as of today the motor has:
https://www.miataturbo.net/attachmen...1&d=1384211673 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 SuperMiata Damper Racing Beat sandwich adapter accomodating an AN6 feed line for turbo valvecover and upper belt cover it got dark so I had to stop. Still waiting on an oil pan and baffle. https://www.miataturbo.net/attachmen...1&d=1384211994 |
I came.

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

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. |
