Well, I expected it to happen.. just not this soon. After 200 miles of being turbocharged my D15B7 said '---- that ----'. #2 rod broke up top creating a baseball sized hole in the block and taking the main girdle with it. I'm not really mad or anything, not like that was a prime engine.

There was no warning when it happened, it was running really strong. I was just out for a joyride and I heard *CLUNK* and then pieces of metal hit the road No detonation or anything was taking place.. it was running great.

So my question is: Where should I go from here? I have another D15B2 in the basement that was running fine... but I know its going to do the same ----.

Which of the D series is the strongest.. because I know what I should be doing is looking for a A6, Z6 or Y8... I'm just unsure which is best or if they're all the same?

My D15B7 was a mini-me, and I guess those twig *** rod's don't like 10.0:1 compression and boost for too long eh

 

how much boost? pics?

 

yeah how much boost, what type of management, we need some info please

 

6-7psi (sometimes it would creep to 8.. but it wasnt at this time), Uberdata as the managment. I can take pictures tonight, I have to yank the turbo/mani off.. the hole is behind it.

 

you need rods and pistons. stock d series internals are not the strongest units. if you want to go mini me again do like i gig, and get a mr gasket mls headgasket. i dropped my compression to 8.8:1 with the srp pistons and crower rods. ill be pushing 16-18 psi

 

well the compression id say is killing you, you gotta keep it down or that extra pressure cylinders upon each explosion is hammering your ---- back down. And if your timing is a bit off, that can really ---- some ---- up.
Another possibility is that clutch i sold you was grabbing to hard, your motor couldnt hang with the clutch

 

I agree that the mini-me is what was the deathblow. I'm going to plop in the D15B2 I have.. it was running fine. I'll just use it as-is w/stock head. I just wanna drive the car again... know what I mean? I don't expect the B2 to last long either, but I'm in the middle of a F22 build and I really can't afford to divert any money into D internals.. it would just delay my main goals.

So much money into everything else that its too fun not to drive

 

man seems like everyone is blowing motors lately..

 

not me

 

you just cursed everyone on this board
