330hp NA street engine
 

This engine just came off the dyno. It's a 3.2L S2 that's stroked (offset ground the stock crank), and bored. It uses PUMP GAS since it's only 11:1 c/r. I ran it on carbs due to ECU harness issues, and expect even more power with the FI. Although I used the biggest carbs available (55DC0), they're a bit small for this displacement. The TB's will allow more airflow and will likely make about 345hp. It would be a hoot on the street, and can be driven to the track to autoX event.

Crazy engine :rockon:

Whats the coating on bolts?

Awesome. Really really really awesome.

Yay more NA development!

it's beautiful! what are the two black nylon lines between 1-2 and 3-4? is it for equalizing the vacuums in the intake plenum?

I want to hear it

Where is the exhaust manifold?

+1 :jumper:


OMG!! I think I just fell in love. Very Cool and very nice build.
What is the rev limit on that engine?

Who Helped you with the Build? And if you do not mind me asking how much did it cost?(just curious)

Oh and Thanks for sharing.

:cheers:

Very impressive!! When do you expect to have it in a car and on the street?

Where do I get one?!

ITBs look amazing :thumbup:

Nice engine! I was expecting a stock LS1 for some reason.

Michael,

Look forward to hearing more from you about NA development on this site in the future.

Joel

care to share with us what it cost you to do this?

that is crazy, but something I would do ... lol

definitely need more info, sound, and a dyno chart...nice looking motor

Dyno Sheet?

Without one its a bogus claim also what about 1/4mile time.
