Stock Car, Motor Swap B13 Senta
 

I have a 1994 sentra 2dr 5 speed. That i want to turn into a stock car to run in our entry (lighting) class here in circle track. The problem is the GA16DE in the car is illegal.
Our rules State
1. NO DOHC ENGINES
2. NO MULTIPORT INJECTION. Thottle Body or Carburetor ONLY
3. NO DISPLACEMENT OVER 2.2 liters
4. Engines must be stock(we can change carb setup)... no motor work
5. Its gotta be at least 95hp

So the cars are 100% gutted. All it needs to do is drive and brake.
So is there any motor that will fit and work, that meet these conditions. Ether keep the sentra tranny or swap it out. Or even a motor/tranny setup from something eles (etc. honda)
Im not sure how interchangeable this newer nissan stuff is with bolt pattern and clutch and flywheels. minor fabrication is do able.
