**Need Help rebuilding an Ls Block and building up a perfect motor setup, long *Pics**
Well guys It's not my motor but my friends, last year at the battle of the imports in chicago it ran a best of 13.7 at 105 and blew up on that run and Terry saw it (Turbot this is the motor out of that maroon integra) but anyways here are some pictures first to let you guys see and tell me what happened here.
I don't have much experiance in this but I think the ringlands on pistons 1 and 4 melted, take a look:
I don't really have that much experiance in rebuilding engines but I know I can do it with the skils I have right now. But anyways as fahr as the setup goes I'm going to send the motor to golden eagle to have their sleeves installed.
Now I was wondering what you guys think I should run for pistons as fahr as compression ratio and bore size I was personally thinking of doing wiesco or ross 8:5:1 pistons but I think If I did that the car would be slow as crap to start out with and I would have to compensate with lots of boost to build the power back up so I need your suggestions on the compression of this motor..??
As fahr as fuel management and turbo goes for this year we are just gona be running some 440's, intank pump, vortec fmu, fuel rail, safc, streight t3 turbo .45 a/r and .48 a/r on the exhaust side, full 3" turbo back exhaust, next years setup will be a t3/t4 setup probably 54 trim size with aem ems and 550's.
Now the head, intake manifold, throttle body has been port and polished before the car blew up and the only problem I see with it now is that when that piston melted or had whatever happen to it some of the particles got stuck on the compression chambers and here is a pic. Look at the top two valves and around.
My question on this one is can this just be polished off or what? Because we are not doing anything with the head at this time..?
Please let me know what your thoughts are on what I should do with this engine as fahr as a rebuild...
Thanks in Advance.

Oh great I appriciate your guyses replys
Nobody here knows anything about engines? Give me a freaking break!!!

I cant see anything from those pictures. If you want to know whats wrong, open the motor, take it apart.

new GSR i'm by chicago and i just bought pistons and now i need to order rods you should come help me and my friends install them since we haven't done it before and it seems like you know what your doing lol
well it's just an offer
well good luck with your engine

Just to add. I am currently in the process of doing my shortblock LS. I have decided to go with higher compression pistons--JE 9.8:1 in Gsr, so about 9.5:1 in the LS. I think it might help slightly in the lowend to get the turbo to spool a little faster.
Basically since the block is getting the GEM treatment, then who cares about the cylinder walls and all. The head may have to be disassembled and looked at closely.
Other than that, I dont know what else you want to hear.

Another question I have is, how big of a bore could I go with before I would have to rework the compression chambers on the head?

Thanks, I appriciate it a lot guys...
Ok for the guys that were asking for better pictures here you are I just updated them all and if you want the bigger and clearer go to the link at the bottom or just click here http://www.imagestation.com/album/?id=4291614597.
After taking the motor apart today I found out that the ringlands on all 4 pistons were broken..

how much boost caused this? and what was his complete set up.
i want to prevent this kind of thing

But the reason the car blew up is because of a shitty deltagate wastgate what happened was the nut that holds the valve that opens up and closes the wastgate came loose and fell off so what was going on is the wastgate was stuck shut so I'm guessing when he was running down the track in 4th gear the boost spiked and caused the pistons to melt and the motor to blow up...

Why put the tiny T3 on the fully built motor. Your motor setup sounds good but the turbo setup and fuel sounds hobo. It has been my experience that it is best to do it all right the first time even if it takes several months to save up the extra money. All of those pistons are melted, some are severe.

I agree with you on the t3 turbo and fuel system but he just wants to get his car up and running till the winter after that we are going with 660's keeping the walbro fuelpump, t3/t4 super 60, and aem ems.
All of the other stuff we are planning to runn right now we already have so he is saving money on that...
Any Suggestions are welcome....
