i[B] own a sing. cam. vtec turbo eg. it is a D16Z6. i have a greddy emanage and finally figured out how to get it to boost the amount the seller was told was possible. getting on it from first through second it pulled like a dream. faster than i had hoped it would! but... we herd it start to run like it was only running on three cylinders and there was oil all over. first thought: oil line popped off. after getting a better look at the oil line and pan we realized there was a whole in the block bigger than a bar of soap. there was no noise indacating the blow. which we cant figure out! do i have some sort of internal problem? what brands should i use to build it better this time! HELP!!! [/B]

Pics of the carnage? (that's just the rubbernecker in me talking)...

Was it a standard Greddy turbo kit?

Seriously, for help on turbo d builds try http://www.turbod16.com/index.php - lots of good info and opinions.

Just curiosity-wise how much boost did you put through it? Stock bottom end Ds aren't good for much more than 220hp on a good tune (I'm sure someone will contradict me on that, but that's just what I've seen).

oh man that sucks. i tell u tho i had the same thing happen to me, not even under boost. it was on a stock motor, it just had bad bearings and when i revved it up to hard it just threw the rods right thru the side of the motor and of course oil and smoke went everywhere, i just stayed on the gas cuz i knew it was done, looked like a plane going down, people beeping at me to pull over, engine lights flashing at me hardcore i was just trying to get it home. Got about 3 blocks from my house before it was just a pile of steaming busted metal under the hood. lol. holes like u said the size of bars of soap.

That was a bearing problem, and I over revved it basically. The main thing that can cause what happened to you or (mechanical failure) with boost, is a bad tune. Any type of lean condition, causes extreme heat and will ruin pistons almost instantly. Thats what it sounds like happened to you, or a combination of the two. was there alot of miles on the bottom end of that motor? If so the bearings were probably toasty as well. you probably threw a wrist pin and put a rod thru the side of the block. Then again, the block could have just had a weak spot and when u had high cylinder pressure from the boost it just gave out and blew a hole. I would say next time just make sure u have a good tune, which means RICH RICH RICH. rich doesnt hurt things like lean does. I mean it can wash down the cylinder walls and ruin your rings and seals, but it wont blow up from being too rich. hope this helps!

maybe you boosted WAYYYYY past the limit because of what someone told you...
