Hey everyone, I posted a build thread awhile ago about my old setup.https://forum.miata.net/vb/showthrea...ghlight=mntech This was my first turbo build so I was very conservative with power and boost. Long story short I was running:

VIDEO: I made a video if you prefer to watch instead of read.
1990 1.6L Stock 83k
Flyin Miata manifold+Down Pipe
Garret GT2554R Turbo
Flyin Miata 1.8 Downpipe
Flyin Miata 2.5" Full Exhaust
Enthuzcar 1.8 test pipe
Walbro 450lph
ID1000 Injectors
Adaptronic e440d ECU
FMIC with 2" IC piping
TurboSmart Actuator with 7psi Spring
3port MAC Valve
I did a pretty conservative tune but wanted some power!

Tuned for 12 psi

208 RWHP
183 RWTQ


Now that power was great but like all of us we want more. That wasn't really the cause I wanted reliability. I had problems with the "custom" IC piping poping off at every pull, the car had a weird idle, sucked gas like no other(bad for E85), and it just didn't run as smooth as I would like. I was running the ignition and fuel wiring stock(batch). I wanted to upgrade my car to be as efficient as possible. To do that I upgraded to:

Toyota Coil on Plugs
COPs running through Direct Fire
Injection running Sequential
Catch Can setup(Both vent and PCV to can)
Mishimoto Radiator/Fans
Treadstone TR7 Intercooler
FM Silicone Piping

Now I didn't change much but after doing these modifications I was curious to see what these changes would be accomplished. The results were pretty surprising.

To note I'm running the same 85k 1990 1.6L, GT2554R at 12psi, E85(70%rated), same dyno, same tuner, same air temp, etc. The constant variables could not have been closer. Anyways the power was impressive

233whp
202wtq


The power and torque curve on the 2 dyno graphs are near images but basically just shifted the power range up. Full boost is still 3700-3800rpm, no drop offs, or cut outs if not a smoother power curve on the updated one.

Basically, this is to show the benefits of running sequential injection, direct fire, COPs, as well as a good efficient intercooler setup.
