OK i have a couple questions......what size motor is in a completely stock 89' V6 5 speed RS with T-Tops..........i heard it was like 135.......and if that is true how could i seriously improve that to some real horsepower without spending a a ton of cash....or would it just be cheaper 2 try n find an 89' V8 motor....just post any suggestions.......thanks

 

3.1 ltr

 

3.1 didn't come out til 90. it's a 2.8 liter. as i said in another post ... the only way to big HP gains in a 2.8 is nitrous. unfortunately your gonna have to have a tranny to go with that V-8. yours won't fit. gonna have to have new motor mounts and modify the crossmember a bit as well. sick
