I'm thinking of building a b18c5 but i want the 2 liters of displacement but I also want a 9k redline (planning on custom installing S2K gauge cluster) what are your thoughts on increasing the displacement of a b18c5 and still revving it to 9k? I also plan on a completely built, balanced and blue-printed bottom end with a 12:1 CR and about a 100-150 hp shot of direct port nitrous. Would love to hear everyone's thoughts on what I can expect to encounter with this project.

 

9K + 12:1 CR + NO2 = BOOM!
IMO.

 

if you still want to rev that high nicely and handle all that Compression and NOS, resleave the block to 2.o L. it will put you like 800 - 1000 dollars in the hole.

 

Remember that N2O doesn't produce as much high-end power... so pushing the revs will result in motor-o-cide.

 

resleeving was always in my plans...and done properly a motor can handle the revs and the spray...especially a B- Series motor.
