I go for the tune on Thursday

dont get me wrong you can use meth without another map, it would still help cool the intake charge and make more power, you would just make even more with aggressive timing.

Ok so a set back.. I went to have the water/meth tune done and we did a base line run before the new tune a/f looked good no knocking but hp on the top dropped off by 70hp

On a compression test 2 of the cylinders on the driver side were low we were thinking head gaskets ok hoping head gasket

So the motor is out of the car and taken apart looks like a piston ring was casing blow-by so I am forced to build the motor with a .020 over bore.

Going to drop the compression by 1 point to a 10.5-10 cr

Man I was not rdy for this good thing I have my zx10r as a back up

Down side I have to drop another 6k to have this done

good news is I will be sitting on a forged motor good for so serious power.

Ps : and yes the plan is to use the on/off switch to switch between tunes
One aggressive tune for water/meth and the other with out w/m.

Wow! Sorry to hear that man! Did you notice anything wrong prior to finding out you had bad rings?

Nissan370 · 03-23-2012, 02:42 PM

i picked this car up from a subaru dealership jan of last year with 24k on the clock one owner before me no idea if the guy ran the car hard or not never had any problems with the car til now.

the only thing when i got the car was it had a spacer on driver side of the rear wheel and nothing on the other wheel and a slightly warped rear rotor
because i dont drive the car hard or much besides to work i did not notice this til months after.

i know adding more power to the mix will pull any problems to the top and i guess for me its bad piston rings

Be happy you found the issue before the engine popped. You would be spending a lot more to fix a blown engine. Good luck with the build!
