There's definitely tuning to do as I'm still on a rescaled basemap but I wanted to kind of rest easier knowing it was a tune and not hardware issue. It's odd that an NA alt worked for you since Soviet has an NA, maybe his alternator was from a non-regulated version.

Is there an external regulator around? Rev, any way to regulate alternator with the MS I have? This was listed as one of my features

+ Digital alternator control, adjustable

Some other random snaps from the build

Mocked up turbo


Headwork, this was a tedious assembly


Porting of the bowls (physical feel is smoother than what it looks like)


Fab9 big boy intercooler


FM Oil cooler


Wedged between the radiator and intercooler is a Derale PS cooler that replaced the OEM hardlines


We made this bracket to keep the coolant reroute hose from rubbing the manifold. We used the center part that was cut out of this piece to make a plate for the OEM catchcan return to the pan


Were able to re-use just one of the stock MSM sleeves on the water return.

That is a very nice build!

I'd love to see some in-car track vids when it is out!

Is that where the stock water return is on the msm's? That area sees ridiculously high temps, do you think that wrap will be enough?

That's not the same location as the stock turbo is a bottom mount. The fire sleeve on that is from the original. Since we eliminated the front coolant neck we eliminated the coolant flow from the housing on the side to the front neck to the throttle body to the oil cooler and back. Basically, the water returns into the tube that plugs into the coolant housing on the side. hasn't leaked yet.

The copper pinched nuts holding the turbo on however have turned gray.

Final results with a low 11s AFR. Could gain more from leaning it out but the tuner said the engine will run at this level forever so I'm happy with the reliability at the loss of a few HP. Funny that this thing makes more torque at 2500rpm than my daily driver makes at peak

Looks totally fantastic.

Took me 3 more PSI to make essentially the same numbers. Edit: but not near as good of a torque curve, and I know the transient response isn't even in the same league.

I want me some EFR....

I've been reading some threads on here and it looks like I could have made more with a GT2560 hahaha

What kind of turbo do you have turbofan? I compared this to Soviet's old 6258 graph and his torque curve is even wilder than mine making IIRC 200wtq by 3000rpm. I'm not far off I don't think. My tuner has only done one other EFR car that had issues so it will be interesting to hear his opinions on the turbo and see some graphs of his other customers for comparison.

The interesting thing is
13psi = 275whp unknown torque (will inquire tomorrow)
15psi = 300whp and 270 torque
17psi = 311whp and 285 torque

I was shooting for 325 at the wheels and he thought it would be possible based on the jump from 13 to 15. Maybe it just made a little less cause it was the last run of the day and he had been on the dyno with it for about 2 hours. I don't think my *** will know the difference between 311 and 325 coming from ~220

I've got a 2871R on an absurdflow Mani.

Mine had similar intervals.

13 psi = 240 whp
14 psi = 260 whp & 220 tq
17 psi = 285 whp & 250 ish tq
20.5 psi = 317 whp & 283 tq

All #s uncorrected.

That one 2560 vs EFR thread makes no sense to me or anyone else so who knows.

I'll post driving impressions later tonight. I was expecting to get my power with lower psi as 99mx5 hit 323/272 on 14psi but he's got higher compression and deshrouded head. Tuner said 17psi is plenty fine and should hold together fairly well. It's not track driven, just spirited on the street and for occasional commuting so I'm hoping to get ~50k miles out of it. At the rate I drive that's over 10 years.

When I joined the forum I planned on getting an FM2 but everyone kept talking about artech and efr and things I never heard of before. Without this forum, this build wouldn't have been possible so thanks to everyone here for being awesome!

I don't think anyone else has had the outstanding results that Ari had. Iono. It seems like your results make more sense. It's always been said that the 6258 provides 2560 spool with 2871 power, right? It seems like it's actually slightly better than 2560 spool with slightly better than 2871 power.

Fantastic.

I just hope that my 3.63s and tires will leave wheelspin to a minimum, I'm honestly a bit intimidated by the torque figure and how quickly it rises, but we hope to get boost by gear wired in. The ecu can do it but we need to add wires somewhere.

At a bit of a crossroads. Have a spal 14" fan that keeps stalling the car. I can have boost by gear OR fan control but not both. I'm leaning towards either finding a smaller fan or a different alternator like soviet did because I do not want to lose boost by gear. I'll get to experience 17psi in 1-6 today and decide but I want it controllable

Right foot traction control? It's kinda fun to just light it up at 40 mph...

Yes it is. Just got it home. Car is incredibly fun and feels smooth and fast. Just gets up and goes like nothing. I'm like a pig in ****. Can't wait to see what it does out there among the other rice in the city.

Now invest in 4x4 suspension to get around those Philly roads and you're golden! LOL
