My first attempt at an all out engine build. I got this unknown mileage/year 5.3 shortblock for $100 on craigslist. Cleaned it up, put in King bearings, newer LS6 rod bolts and some 317 heads with Patriot Dual extreme valve springs. Found a steal on this Incon stage III kit. It only came 80% complete, missing only the bits and pieces. Let me know what you guys think!

 

Interesting... I could use something like that on my wife's g8

 

Just curious, but how did this ever turn out?

 

Going in the car now. Got setback when I got deployed for a couple of months. Decided last minute to go E85 so got to get with Lonnie for a setup.

 

Moar pics!

 

Alright guys after 3 deployments and numerous TDY's i've finally got this thing installed. People weren't kidding about how the nickel and dime stuff adds up! So my question is i'm down to just needing a 2 bar map sensor and i'm set and ready to go to the tuners. I picked up a GM part # 12615136. Just wanted to make sure this is a plug and play sensor. Will this work?

 

Yep thats the right map!

Best of luck on the tune

 

Thx Steen!

 

So those Incon setups actually fit? I guess they need a scavenge pump?

 

Cool! i cant wait to see the results.

 

I got the base tune but i'm pretty sure I have a bad map sensor plus its so pig rich it burns my eyes!. It's reading 88 Kpa when it should be in the 101 range. I got it off flea bay so i'm going down tomorrow and getting an AC delco unit. Hopefully tuned this week.

 

Well I got to spend some time at the tuner today. Not too shabby, still working on the street tune. Apparently I have more injector than i need. So on to the pics!

This is how she started!


I found a 2002 5.3 for $100


Needed some work


Got the old motor out



Stripping it down



Took the K-member to get sandblasted and painted


Tapped the oil pan


These things were nasty



Got the motor back from the machine shop and assembled it with new rod bolts and clevite bearings



LS9 head gaskets


Installed some 317 heads with Comp cams double springs


All cleaned up



Going back in


Looks good going in!


Did the trap door mod


255 Walbro's hooked up


Fuel bucket c/w....this wasn't how it went in. I was able to get proper fuel hose and looks pretty good.


Had to figure out how to get this cover back on so i welded some self locking nuts to some tabs


Cover on


Covered with heating/air conditioning tape. It's aluminum and nothing gets by it


Built a custom exhaust using Y-pipe from flea bay


I haven't welded in 10 years so i'm happy with my mess!


Engine bay for the most part. The IAT is plumbed in



I'm also running a snow stage II methanol kit running boost juice. Just swapped out to 10psi wastage's. Can't get to the dyno until next Thursday. Once done i'll post some results.
