Cavalier Project $2000 car build
Stock 2.4L 4cyl 96 horse power
Installing 3.8 liter V6 225 hp
Pulling some parts off. You can see the Buick the engine came from that was donated to the school.
3.8 installed and body primed white
When we went to bolt the supercharger on we discovered why everything said we needed to replace the heads. There were no holes in the heads for the injectors. The (N/A) natural aspirated engine had holes in the intake. The supercharged engine had them in the heads. We had to go to the junk yard and get heads.
Now where do we install the injectors :0
Got to keep everything clean good job John
Trying different options
Super charger time 🙂 + 100 hp
Installing blower / supercharger looks like there are injector holes now 🙂
Bought some aftermarket bolt on’s
Bolt on header kit, Plus wire protector, 2.4 pulley+ 15psi boost , wires, plugs +50hp
Pulley upgrade, small pulley = big boost
Northstar throttle body upgrade
Northstar mass air flow
80 pound injectors at 43psi 860cc “note we run 65psi” = 1200cc
Had to remove engine parts to install headers
Heat shields to protect everything
Installing throttle body
Methane time 🙂
Installing some new shoes
New shoes (Big fat racing tires)
Off to the track
Our best time at the track so far was 8.44 but the speeds were really slow. At the end of the track it was not shifting into 3rd. It was running the rev limiter a lot. We brought into class to do a shift kit.
We had to remove the side cover to remove the valve body
The frame and everything came out
Here is the valve body with new gasket we ground some valves replaced springs plugged some holes and drilled bigger holes in the plate. We even had to drill the case.
When removing the Accumulator’s we found broken springs. we are installing new pistons and seals as well.
We dug a little deeper after that
We also took a look inside the transmission and we found 2nd gear clutch pack fried
Pretty much any forward clutch was fried.
We gutted the entire unit
Rebuild kit arrived time to install some parts
