Ecotec swap with new exhaust, new dyno and drag!
5 Attachment(s)
Finally got the Eco swap car back from having the entire exhaust reworked. New setup is 4-2 upper header section with 1 5/8" primaries, v banded secondaries that go all the way under the trans and over to the stock cat back flange location and merge to a 3" v-band and a 3" exhaust with Vibrant ultra quiet resonator and Borla oval muffler.
Due to matching the cylinders unevenly (1-3, 2-4) the car now sounds properly good. Attachment 182945 Attachment 182946 Attachment 182947 The car had a huge hole in the torque curve which also showed super lean, so we had to rework the vvt tables and fueling to smooth it out. New highest numbers are 192.5 whp and 195.4 wtq. Attachment 182948 I was heading to Indy to hang out with concealer404 for a birthday skydive (which got rained out) and figured I would stop by the strip on the way. That trip resulted in several of these: Attachment 182949 Still not quite enough for me, so I will reassess the build this winter. I may even go back to a BP and build a 1.9L GT2554R setup with a billet compressor wheel for maximum spooling 275whp swaggotry. A 4.8L GM swap was also spoken of due to the potential for crazy revs. |
Wow that's a nice improvement compared to the MATG version. I really dig the exhaust tone, I've been a huge Borla fan since using them on my SR20 cars back in the day.

It sounds so good. How loud is it in cabin?
|
Damn it sounds good! Good job on the track times.
|
Just curious about the video...am I hearing the tires chirp on the 1-2, 2-3, and the 3-4 shifts?
|
clean, peppy, and sounds good.
grats :) |
Anyone added a turbo to an Ecotec'd miata yet?
|
OP totally should because it would make delicious torque and be the coolest street car
|
This thing's bad ass! A high 13 at 100 is fast. With some boost it would be insane.
Nice job! |
|
still internally stock right?
so i guess all it needed was an exhaust and a proper tune. sound awesome, congrats. :likecat: |
Very slick setup. Sounds good, runs good; and look at that torque!

More compression! More cylinder head! More induction! Ah Ha Ha Haaaaa!!!

Is that a heimholtz chamber that T's off to the side near the diff? or a exhaust cutout deal?
Sounds good. I likecat |

Will you guys be mad if I pull this setup and swap something completely different in? Maybe with a turbo?
