Miata Legacy Build
 

For those of you who didnt see my meet & greet post on the back story to my miata, it was my best friends car who passed away from brain cancer. He had plans of adding a turbo and doing autoX but never had time to do it. About a year after his passing his dad gifted the car to me because it didnt mean much to him and we had a lot of good times in the miata. I enjoy building cars and plan to track this car and have a fun toy for the nice days in the NW

When i got the car it had the following installed

• 1.8 torsen diff
• Jackson intake
• Brain built MS3X
• 2.5 exhaust
• Bride Lowmax
• Hardog rollbar
• Tien Flex
• 14x7 RPF1 set
• 15x7 BBS knock offs
• Braided brake lines
• Front strut brace
• Engine roll brace/damper thing
• Nardi wood grain steering wheel

• installed gt2860rs turbo
• full 3" stainless exhaust w/ magnaflow
• 1.125 RB Hollow front swaybar with 949 endling
• Singular hood vents
• Custom heat shield
• Catch can setup
• Bunch of heat shield and heat management stuff
• Good turbo hardware from arp turbo (i know its not inconel)

That heat shield sure does hide the turbo well. At a glance you would miss it.

Works really good I lined the inside with motorcraft heat shielding too

Should get my wheels i ordered a while ago tomorrow. Got the 15x9 Advanti Storms and will order some Hankook RS4's.

Do i order 245/40r15 or 225/45r15 Keep in mine i have AK fenders on the shelf at home

245/40r15 on a 15x9 storm will fit under stock fenders rolled and pulled. With flares they will probably be sunken a bit.

Got some advanti storms s1 wheels in 15x9 for a great deal. Should see some 245/40r15 Hankooks in a couple weeks

Coolant hit 215 today in driveway and turns out fans didnt kick on. shouldnt the thermo switch kick in at 200ish? If its bad should i run the fans to a manual switch or just replace the thermo switch?

Replace the sensor. If you run manual fans, at some point you will forget them and overheat. I've done it in previous cars.

Ms3 should control the fans.

On a Brain built MS3 it looks like the fan output for a 90 should be INJ G. Should be able to use test mode to turn on that output which should turn on the fan. If it doesn't you'll need a DMM to measure the output at the ECU.

Really cool thread. Kinda off topic, but could you tell us how the rear deck speakers sound?

Got the MS3X to contorol the fans and was super easy, cant believe it took me this long to set it up. SpartanSV it was ING G. Viperormiata- the speakers are alright and like everything it is all relative. The speakers are clear but i have to crank it up to hear anything over the exhaust but race car not luxury car. The truck speakers sound way way better but i actually put a good system in it (amps proper build sub box, good speakers, good deck, quality wires)


Do these fan settings look good

Now you have me confused. Was it injector G or ignition G?

The link was to Braineak's site and his diagram which shows injector G as the fan output.

From Brain's 97 base map. Looks like he sets it so the fan turns off over 90% throttle which is genius.

Are you using a vTPS?

With your hysteresis setting you will never see your fan turn off. With brain's it will shut off at 190.

Copied your settings and fan works good. Also had to drive at night yesterday and tuned the PWM voltage compensation to account for the headlight draw and if i turn the heater fan on.

Got CL idle to run pretty good just now. Can anyone see any major issues?

Also pulled the trigger on some 245/40r15 Hankook RS4's today should show up Tuesday and was able to get them for $125 a tire.
