As many of you know I was one of the first car’s for SMG to install a remote mount twin charge kit.

The car was a blast while it ran but encountered some problems here and there which was expected being the 2nd car to have this done to. Eventually the power came to an end.
I was driving onto the onramp to get on the highway and as I was merging on it happened... smoke started pouring out of my exhaust pretty much blinding anyone behind me. I immediately smell that sweet smell of anti-freeze and assume I blew the head gasket. So I get it towed home and order a cometic head gasket.
A couple weeks later or so a friend and I take apart the cylinder head to replace the gasket. Before even looking further we immediately noticed the old gasket was fine which is where I knew I was in trouble. I look down to find this.......

I now knew I was screwed and it was either a new block or rebuild it to extreme. A couple months or so went by as I was deciding what to do while I saved up. Finally I came to the decision to go all out and just rebuild it to extreme. Well to as extreme as I could with the money I saved up haha. Below is a list of parts that will be used in my car.

The car has currently been in the shop for about 5 months now and off the road for close to a year. I talked to the machine shop and they should be finished with my block in about a week so Fred will be able to start assembling and get this this running again.
Also, Fred told me he went over-bore on the new sleeve kit as well as installing larger pistons. He said the car will probably be a 2.3l when all said and done.
Now I don’t have the best technical knowledge when it comes to automotive but I always try to do research and love hearing other people opinions and suggestions. So any question or comments please post and Ill be happy to answer them or at least try and get the answer for you.


Below are COMPLETE pictures of the cylinder head porting









This is a picture of the block at the machine shop almost ready to be picked up by SMG to be assembled



Below are a few pictures of the Darton sleeved block now finished from the machine shop and at SMG for assembly





Below is a picture of the block coming together. Pistons and rods are in and cylinder head is about to be attached!


Below are pictures of the block being assembled








Below are pictures of the motor going into the car (valve cover was someone else’s and is going to be repainted)









These are all the pictures I can fit on this post. A few pictures uploaded on page 4. On page number 10... dyno chart + video of car with 2.5” exhaust and resonator. Final chart and video soon to come once exhaust work complete

 

i know this might be a nooobb question, but what is SMG

It’s a performance shop located in Hopedale, MA. Thanks man, yea the twin charged is something I really got interested in haha. I sure will!

 

Good Luck!

 

beastly! should work well when its done

 

good to see someone fixing an lsj when it breaks instead f just saying "stupid cobalt, im buying a v8"

 

Thanks, yeah I hope it is! I just need to start thinking about upgrading the tranny!

 

yea no **** op good luck

 

sub'd

 

interested to see how this turns out. good luck!

 

Looks like it's gonna be good when all said and done...good luck man

 

That porting looks pretty rough.. I hope those are in process pics. Hit them with a flap wheel quick LOL..

At least you broke it good, always sucks when its a wimpy break IMO.

 

cant wait to drive this!!

 

ah I can't wait till she's back. I miss hearing her streets awayy...and my dad would be like "Oh bryans almost here..I can hear the car" .........ahh i can't wait till Cobies back =)

 

What caused the engine failure? Bad tuning or too much boost?

 

click

 

Good luck with the build!! In for results

 

this!

 

Click in for more pics/rebuild story!

 

Nice. gl with the build i know how it will feel when stuff doesn't go to plan. it happen to me many of times with my build

 

he was running over 360hp on his stock block. thats pushing it for power on the stock LSJ

 

No it isn't...

 

yeah that power is not really pushing it for the lsj... but I have heard the twincharge setup is a little different with stress on the motor.

 

WHAT!?!? lmao

 

Do we know if this was a compounded setup?
