hi and happy new year few days ago i was using my rx7 vert six port turbo.Some mod are street port and a s5 turbo intake manifold n318 ecu n318 boost sensor. i never use the car raining ,because my wiper switch is damge long story short* i was using the car and a rain start. I was driving normal true the rain i get to my home whit out a problem. few days later i was going to start the car and nothing happen the car get to my home whit out a problem. few days later i was going to start the car and nothing happen the car crank ok but no start I check compression an is ok ,check spark an is ok, change tps check fuel injectors and are ok change ecu and is ok, fuel presure ok.I was able to start the car but start after crank several time and whit the pedal to the floor.the car start whit a wierd sound and i have to give it gas* to mantain the engine on. whit the* pedal to the floor the rpm slowly climb up

 

chipped/cracked an apex seal from detonation causing slight compression drop. assuming 9.4 to 1 compressor rotors, the factory turbo ecu, even 93 octane can't save you from over boost.

 

i check compresion and in both rotor i have over 95 +

 

i run super seal apex seal
