just replay the rods/bearings/maybe valves if they got bent and I think your engine will be ok?

@tommyblunt if you read the comments below you'll see this was a customer's car whom we built an engine for. typically when a rod bearing is spun, the head and block are fine. you could machine the crank, though i'd honestly replace it.

:( poor MS3 thats why i wont tune mine

[ProtegeGarage]

@LFADRIFTER modifying and not tuning is precisely what lands you in this predicament though. i presume you meant you're leaving the car stock

@ProtegeGarage if u offer replacement parts from ur shop would u happen to have just a replacement variable cam timing actuator or variable valve timing actuator for an 07 mazda 6 2.3? as ive been finding in my readings, i cant find just the actuator anywhere.. everybody wants u to buy the whole kit thats like $400+ and that involves extensive work to replace all of that instead of just the VVT.. please help with thanks from houston with no car now and hardly any money being unemployed soo long

Funny part is about these motors are they are very tough and almost bullet proof up to mid 300's. Problem lyes in the ECU. Its one gig away from being AI and likes to think on its own, which isnt the best thing for it. There is a local guy who slapped a Borg Warner of some large size to his Stock MZR and almost cracked 500 hosre. Its not that the engine cant handle it, its the Tune that has to be spot on to eliminate KR and keep fuel and timing where it should be.

[SB34Fireball]

@ProtegeGarage Exactly...

If someone knows what they're doing, a tune means eliminating KR via editing fuel trims and such.

I've got no idea where/why people get the impression that tuning = physical modding

[nickthastick]

@ProtegeGarage Dammit, that is a little to far away, are you familiar with puting these motors together??
