LSVTEC Turbo Carnage
Well, it was fun while it lasted... 363 whp on dynodynamics dyno.
Setup:
LS block, stock sleeves
Eagle Rods
SRP Pistons
B16 head, Supertech Valvetrain
Maxrev log mani
SC50 .63 hotside
2.5"dp to Thermal 3" exhaust
Tial WG and BOV
RC750's
AEBS intake mani
Tuned on crome pro
GSR tranny with OBX LSD
ACT XTSS
Not one, but two cylinders, lol... sleeves 3 and 4 are busted.
Pistons look good from the top. I've got some soul searching to do to see what my plans are. Any suggestions or recommendations?
Should I rebuild? What would I need to get or replace to maintain say 450 whp? I was thinking sleeved block, twin disc clutch and maybe a different turbo...

Re: LSVTEC Turbo Carnage (eg crunkmonster)
your lucky!!! Sleeves normaly break off and ruin the pistons/bearings/head all at once. Looks like a great time to pick up a sleeved block to throw your goodies onto!!
When did it happen? And what kinda fuel setup? How much gas do you have?
Me + a lot of others i know of did the same thing a year + ago by running a 1/4 tank of gas during 4th gear pulls at the track or on the street. Walbro's can sometimes starve and cause this with not enough fuel in the tank.

Re: LSVTEC Turbo Carnage (JDMs1eeper)
what caused this?
as mentioned earlier, the sleeves don't appear to have broken into pieces much (screwing the head / journals etc). so that certainly helps if you were looking to rebuild

not always, but at 363whp unless there was some history with this block, i'm thinking its a tuning issue.

I'm not looking to blame anyone for this... I will tell you that the dynodynamics dyno is conservative like a mustang dyno. Before I went LSVTEC, I made 280 whp on a mustang and 340 whp on a dynojet. I never had a chance to get this setup on a dynojet, but I'm suspecting that the power was more along the lines of 420+ whp. My opinion is that it was just a bit much for stock sleeves.
I had a full tank of gas and this happened at the track, right before the end of the 1320. My fuel setup is Walbro 255 and RC750's. We used a stock FPR because my B&M was bouncing all over the place at high boost.
Hopefully I can get her back up and running... Any suggestions on upgrades?

Re: (Rhythm)
how did the plugs look?
did you retune w/ the stock FPR?
correct me if im wrong, but the B&M wouldve raised your fuel pressure 1psi per psi of boost (1:1 FPR)... so that would throw your tune off.

stocks are also a 1:1 ratio FPR.
More then likely it was a fluke. I ran a LS turbo at 400whp range for a year once and had this happen to me. It seems to be the magic number at 400whp for sleeves to fail. Yes some people have made 600+ but they dont daily drive on that power and beat on it daily like some of us too.
Its like an egg shell. You can toss it around the circle to your friends but sooner or later your gonna get fuckd.
good luck on the rebuild, dont let this get you down. Just upgrade your sleeves, your retainors and springs and clutch. That'll be good to keep you reliable for a long time to come.

Yup know of a few people with LS's that have cracked cylinders at about that hp range as well. Maybe a little less

Tuning is only for fuel mapping, ignition timing, and things that lets the car drive nicely. Tuning would not include a fuel pump falling behind, high IAT's on that particular day, or a bad fuel pressure regulator. Nor tuning accounts for mechanical parts failing such as a weak alternator (which leans out the A/F or causes a weak spark). Stuff like this is way more probable than a tuner maybe giving the engine a little bit too much timing.
A good tuner should also factor in potential causes of blown engines. That is why it never works to "pull into a dyno" and let the tuner do his thing in an hour. It is a complete system, and the tuner should know how to point out potential dangers to the customer and urge them to replace or upgrade certain parts. It's a whole package.

Thanks for the link ^^^
I've seen people go with Benson, Dart, GE, etc... Anyone have any specific experience with any of these? There was a place in the vendor section that had GE blocks in stock, ready to ship.

yeah I went threw 3 LS blocks that cracked like the picture above so I just swapped blocks and reused the setup. The 4th block cracked and the cylinder walls fell in and killed my nice head and my piston. They were beat on for a 6month to a year period daily at 20-25psi. (400-430whp range)

Re: LSVTEC Turbo Carnage (mtber)
Funny, the same exact thing happend to M.A.R.C.'s LS at 315whp/15psi ...but I took all the blame 
Strange how it seems to be only (or certainly for the most part) an LS thing. *shrug*

wow. i'm surprised the piston still looks pretty good. how long did you have the car boosted for?
only thing to do is to sleeve it now. i don't it'll matter which company sleeves you go for. they're all nearly the same. it'll probably narrow down to who has the best customer service and turn around time.

I'm sure there is history with this block. There is history with most LS blocks at this point in time
It's hard to find a block that doesnt have cylinder sleeves that have stress / hairline cracks, etc. Yes. Many have made 300whp, 400whp and a few have made 500whp and even 600whp. Not everyone is going todo this with stock sleeves
