For the first of many engine builds at Street Muscle Action, we couldn’t just settle for something ordinary. No, this is a new century re-imagining of Buick’s turbocharged V6. This time around we’re talking about a 76 millimeter turbo, 42 extra cubic inches and total output of over 700 horsepower. So far we have the first three video installments in a series chronicling the entire buildup. Up next we will bolt on the turbo and get it up on the dyno, so check back regularly for more!
The first video in the buildup (above) is all about building the foundation. We’re preparing the block to be able to withstand 700 horsepower and installing the crankshaft.
Part Two
The rotating assembly: Plugging in the connecting Rods and pistons.
Part Three
Cylinder Heads and Valvetrain: Making old aluminum heads new again and bringing the valvetrain into the 21st century.
yea just want to when will it be ready and how much?
I believe the owner told me the cost was somewhere around 12 grand, but your mileage may vary depending on your engine builder. Currently the engine is in the car but with a very (and I emphasize the word “very”) mild tune. The owner plans to get the car to a tuner soon but money issues have kept him from getting it done. Believe me, I’d like to finish this series off with a good dyno session!
Does the build up of the engine include parts?
Yes, that $12K definitely includes parts, but it has been a while and I don’t know if the prices have changed. The builder was KT Engine Development and their number–which I don’t think they will mind me sharing–is (704) 784-2610. If you build your own version, make sure to let us know.
I have a built 4.1 also in my GN which is pretty much the identical build (minus the fancy coatings on the pistons and extra oiling mods). I was very interested in the oil sqirters. How/where did you find the squirters? I am looking at doing the same to mine because I have a crankcase evac system and crank scraper which is going to keep windage down however without this oil splash I now need to add some cooling to the bottom of the pistons with squirters.
I am also going to add about 1″ of to strengthen it also.
Have you done any dyno tests on this engine and what numbers did you get?
Meant to say 1″ of hardblok.
