Hey Ryan,
I replied to your pm, keep us posted
...
unfortunately, when an engine encounters a catostrophic failure such as yours, the chances of having any salvageable parts are slim to none
BUT, we can help you out with the core charge

Its your other explanations of running lean vs rich that have us stumped. I would suggest you read a little more into that before posting nonsense. If anything that is where people are doubting you...anyone can post what shops and others have told you but actually understanding it is another dimension..

^think you guys have it backwards.
cylinders 1-2 are the ones that get starved for air since the plenum slopes down towards the front and they are the farthest from the TB/air inlet. The angled spacers bring the plenum back to a even height and even flow. SEE this ad description:

Solo, i feel youre back peddling with the 5-6 cylinders comment. IMO, i think you thought 5-6 were 1-2.
And before you go busting my *****, yes i installed my sc.
Ive installed:
injectors
aam plenum spacer (removed as well)
vortech sc
Ur crank pulley
test pipes 2x
exhaust swap from stock to mod to stock again
intake several times
fuel pump
full suspension swap including sways/camber arms
full nitrous setup
i wish i could do motor work tho, props to those that can
Regardless.........
Hope the op gets it back together! love to see you doing your own engine work. Im just to nervous because once its apart, ive got to put it back together again.
What about getting a prebuilt shortblock and swapping it? Prices dont seem to bad on those and since you do your own labor itll be much cheaper.

Installed and tuned myself, been running strong for a long time now.
We have actually been talking about the same cylinders just we were numbering them differently. Regardless you said that cylinders that are starved for air run lean....
Sorry to take the thread off topic, I just hate when people spew mis-information.

Also so your agreeing that you are saying all those people I mentioned above are wrong and your right?
Tell you what, think about how a engine WORKS for a minute then you might get it.

Exactly they do run lean. If there isn;t enough AIR there isn't enough flow to mix the air/fuel into that cylinder. Less airflow, means less fuel. DUH!
The statement that airflow is needed to carry in fuel is correct but you are not taking note to the fact that an engine sucks in air and even without a turbo there will be airflow to pull fuel into the cylinders. When you boost a car this is even more amplified (assuming a laminar flow with minimal turbulance at the valve) and if one cylinder is recieving 5psi and another is recieving 1psi of boost there will be the same amount of fuel unless the injectors have been tuned individually for each bank.
So just to be clear this was a T66 turbo used on the Turbonetics kit tuned using UTEC by GRD with 750cc injectors? Just trying to get an idea as to what exactly was in play here. I'm guessing this was D35010s old kit?

Unbelievable how some people think. I can't seem to explain it any better for everyone here. Think of it this way. You have a FAN, then you have a mist of water spraying in front of the fan. The fan on low will spray less mist in your direction than it being on high. Same goes for that cylinder. Less airflow, means less fuel going into that cylinder. It isn't that hard to comprehend.
PS, learn to spell receiving better.

miaplaya u r correct this is dill's old kit...
u guys r hilairious and yea the block is toast....but there r a few vendors REALLY helpin in the $$ depot...i dont think i am gonna have to sell a kidney or my girls ring to fix this one...lol
