Build: Supercharged Ecotec NA
 
Purchased this car in June of '17 as a dedicated track toy. Having built kit cars etc in the past wanted something that was less of a unicorn, and something that I didn't need to spend every waking hour wrenching on. My kit was 99% wrench, 1% drive. For this car I don't want that level of wrenching if I need something installed, take it to my mechanic, I just want to drive! The car came to me with the Ecotec swap already done, I had almost bought this car in '16 so when it came up again last year, I jumped at it.

When​​​When bought it had the following:

1991 Miata in White w/ 246,000kms
hard top
Ecotec 2.4
5 speed
HSD coilovers
upgraded front sway
Stock rear sway
15x7 Enkei wheels, puck hard Dunlop Direzza tires (205/50)
Flyin Miata 4 piston Wilwood kit
stock seats
MT Motorsports Roll Bar
Original never rebuilt control arm bushings
Open diff
​​​​​​Alpine stereo
no power steering
No aircon

Since then I've done the following

custom 2.5" cat back stainless exhaust
3.9 Torsen Diff w/Delrin bushings
15x9 Advanti Storm S1 with used RS3 (new tires this season)
New Xidas with 800/500 springs
Kirkey Intermediate Road Race seats flat floor mounted
GForce 6 point harnesses
Fully rebuilt control arms from ISC racing (delrin and sphericals)
Removed door cards, replaced with aluminum
AutosportsLabs RaceCapture/Track
Removed stereo
Removed speakers

This coming season:
Supercharge the Ecotec (Cobalt SS Supercharger)
full front air dam with splitter
rear wing APR 200
Remounting driver's seat even lower (I'm 6'3)
Upgrade roll bar for better harnesses install
TrackSpec hood lovers
New Rivals or RS4s

Here's a picture or two.

That subframe rust is nasty! Car is looking good, can't wait to see what it does with a blower. What version of LE5 do you have?

Yeah, I'm going to eventually use V8 Roadster front subframe and wire brush and POR15 the rear.

LE5 from a 2013 Malibu of all things.

Nasty? That's a damn clean car in this area.

Haha, all relatively I guess.

Here's what it looked like before I did control arms.https://cimg3.ibsrv.net/gimg/www.mia...60e25c65c8.jpg

Do you like the Trackspec Hood Louvers in terms of cooling did you notice a significant difference? I've been wanting to order a set but debating between Singular and Trackspec as they are both on backorder.

Yeah they work well my under hood temps were most higher before.

how did you fit the cobalt ss supercharger? Did you cut and weld an elbow for the throttle? Some more pictures would be great! Love the build btw

Yeah, the intake needs to be cut and rewelded, not complicated assuming you measure twice cut once. :)

That is perfect. That’s how I had thought of doing it. I have a spare m62 supercharger at home I can try to do this and see how it turns out.

Just curious of you heat exchanger setup, Which one did you end up with? I am debating turbo or supercharger for my ecotec swap. Just got the swap all finished up. I ended up putting some 3.08 gears in my ford 8.8 and would like the lower end torque of the supercharger to pull it at the lower RPM. Trying to come up with a parts list to try to start putting everything together.

No issues. Car is actually down right now while I convert to a PDM and redo my chassis wiring. I think I have some video kicking around, I'll see what I have. Post lots on Instagram @DogsBollocksRacing
