Turbocharged LS Engine Build
So I decided the 383 stroker engine that I was running in my 1986 IROC Camaro wasn't quite enough. The car was running high 12s at the track, but I was already acustomed to the power and was looking for the next level. I decided to pull the engine in favor of an LS style with a turbocharger!
So I grabbed a 4.8 liter engine out of a local junkyard from a wrecked 2000 Chevy Tahoe and began pulling out the old one. I found a guy from Kentucky who wanted it and he came all the way down to put cash in my hand. I yanked it out and hopefully the motor is pushing his project car around now.
With the new engine set in place, I started massaging things with a hammer and cutting the original 4.8's accessory brackets to see if I could get them to fit under a stock camaro hood. This needed to be a sleeper!
It looked like it was going to work so I put a belt on it and called it a day. Great luck too because to purchase accessory brackets from a newer camaro to fit mine would have cost over $500.
Next I recieved a chineese turbo off ebay and took at apart for cleaning. It looked pretty good! Also since I was going from a carbureted engine to a fuel injected one, and the junkyard had cut the previous engine's harness, I decided to build a Megasquirt 2.0 control board to handle the engine's fuel management and ignition timing. It took 10 hours to solder up the board. The full task can be seen in my other project!. Last step was to start wiring up the engine's stock sensors to the megasquirt computer. A painstakingly slow task.
Finally I had it looking nice and neat! After a lot of fiddling with the computer's settings and lots of adjustments and troubleshooting, the engine fired up!
With a mounted and running engine, it was now time to start on the turbocharger mounting, piping, and oil line routing.
I decided to resuse the stock chevy tahoe headers, but flip them upside down to feed the exhaust into the turbo.
