Raiden8816's Hybrid Ecotec Build Thread
Decided to make yet another build thread!
Two years after being supercharged, my L61 decided that it's time to call it quits. With roughly 800 miles until it hit the 100K club.
I was having some festivities with an Evo 8 on Saturday (02.02.13) and was winning by a car and a half then she went pop.
After taking a closer look today (02.04.13) it seems like the #1 rod broke in half and took out my oil pan along with a nice portion of the block.
Below is the damage.
The current plan is to get a 2006 LE5 with forged internals to use as the long block and piston/rod combo. Then we will use the L61 head and bolt her back up with a nice crank trigger to make it all work and play nicely with the M62.
My current setup before the supernova going pop.
- Eaton M62 w/ smoothflow pulley 2.9
- Siemens 80lb fuel injectors
- RAW 3" CAI
- OBX 2.25" Header/Downpipe combo
- Custom 2.5" Mandrel-bend exhaust piping
- Dual-Pass w/ Option B tank
- Stock LSJ heat exchanger
- Magnaflow muffler
Once she is back together I will push the LE5/L61 harder in trying to break the 250HP limit that GM put on the rod rating for the L61.

Usually people break the rings and things are simple. Mine just had to ride the rebel bus and blow a hole in the block lol.

As for cooling, I had a dual-pass with option b tank. I had the stock heat exchanger which is fine for the application. Even John Powell doesn't use front mounted heat exchanger since the stock is fine the way how it is.
Now if I had a Griffin, well that would be another story

I was in the process of getting a ZZP 3" DP off a member here plus ordering a bad mab header with taxes along with a Tjin carbon trunk. Now I have to worry about the engine.
But my friend is gonna let me borrow his stock LSJ H/D to mock with the engine until I get the proper parts during the build.

Sad the motor popped bro. But I'm excited to build the hybrid for you and pull the old motor and see what happened.
Last I left the car his afrs were low to mid 11's and iats were 120ish after 2 back to back pulls in 65* ambient. I gotta check his logs to see where timing was.

Updated pics since the teardown.
First assumption was incorrect about #1 being destroyed. What actually happened is that the ring blew on #2 which also lead to the rod of #2 being snapped in half. Since the car blew up around 3,000 RPM the half-broken rod basically buzz sawed the block in half. It also destroyed both neutral balance shafts and also snapped my heat exchanger pump bracket
The good news is that the head is in perfect condition along with the valve springs, rockers, etc.
So the most important part of the hybrid is ok for the swap.
Pics!!!!
Front of engine
Closeup of front
Hecho En Mexico??
ECOTEC PIECES EVERYWHERE!!!!111!1
The non-beefy pistons that come in the L61
Will it blend or buff out?
Jigsaw anyone?
Yes, some of the SC bolts got bent too...
Back of engine / what's an oil pan?
Closeup of back
In better light
The piston was actually sideways like a boxter engine when it was still inside the cylinder.
Last picture while the engine was in the car...
On a positive note since I doubt any junkyard would do a core exchange on destroyed engine block, I will make a table out of it!
