The More the better! NA6-GT2554R-E85 -12PSI
2 Attachment(s)
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. :likecat: 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 https://cimg8.ibsrv.net/gimg/www.mia...fe1fec6e40.jpg 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 https://cimg1.ibsrv.net/gimg/www.mia...caf55be3b3.jpg 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. |
