recently purchased this car from a forum member..
87 turbo 2
mild port
fresh rebuild 0 miles with super seals(except driving it onto the trailer to tow)
haltech e6x
new 1000cc primaries , 1600 secondaires
turbonetic t04e
full 3 in exhuast all the way to apexi n1 muffler
50mm wastegate
2.75 intercooler with fmic
msd box

so heres the story..car sounded great started up no problem,ran super rich since it still needs a tune.Then my friend hooked up the battery backwards on accident given it was night time.So that ended up burning up the alternator and both coil packs,replaced them and car started right up sounded as it did before.So i towed the car,once i got it home it sounded like its running on one rotor and has no power??? cars getting spark and fuel as it did before.

dont have access to a piston compressor tester or a mazda one as this is my only car..

 

by the way i removed the trailing plugs to do the test not the leading..not sure if that makes a difference

 

Test the front and rear rotor individually. Leading/trailing plug does not matter. Listen to the videos at the end of this thread https://www.rx7club.com/2nd-generation-specific-1986-1992-17/400%24-1986-na-rx7-help-appreciated-983280/page4/

Check your engine and interior fuses after the backwards battery install.

 

will do right now
thanks for the response.

 

Deflood the engine one rotor at a time and listen for the 3 whooshes.

Should probably check the timing too.

 

Good news!Got the car running on both rotors again.Did the timing,put in a s5 tps,and rewired the coilpacks into the msd and its running as it did before the issue.Now all i need is a base map to upload onto the haltech,so if anybody is running close to the same setup that would be great=]

thanks for the help,much appreciated

 

I clicked on that link and it took me to my own thread lol. I thought the rear rotor sounded bad but now I'm unsure haha

 

yep..FB331 your famous lol
