114K on a B18A1, new pistons installed 20K ago, new timing belt, perfect 150psi compression across all four cylinders. T3/T04 running 7psi, with TUNED HONDATA, no other precautionary measures. Possible?

 

your compression is 150? i have a d16y8 and mine is like 190 or 210 i think. why is it so low?

 

who knows. The engine is scarily strong though, it makes 133 to the wheels with just a short ram intake.

 

No worries at all, the compression does seem low though.

I am running a 231K miles D16a6 with 7 psi daily and Zdyne ECU and I still carry over 170 psi compression. Your b18 should have higher compression numbers.

You should be fine.

i dont think they mileage number is as important as how good of shape the motor is in. If you just had new pistons in recently, I assume you had the cylinders honed, and everything was put in right. As long as that compression is a typo, then you should be good.

 

231k miles.. that's amazing. How much does a tunable ZDyne ecu cost?

 

150 doesnt sound that bad, i find some testers give lower #s than others.
