Hello all,

My B16a1 made 198bhp on OBD0 & BRE. I am swapping this head onto a B18c4 block, and I am swapping my pistons as well. Essentially its the same engine but with 1800cc rather than 1600cc and OBD1 rather than OBD0.

My question is - what horsepower gain is reasonable to expect?


The final build will be -

B16 pr3 head
Blox Type B comp cams
Blox Cam gears
Blox Retainers & Springs
CTR Pistons
RC 310cc Injectors
Tri Y manifold
Skunk 2 70mm TB
ITR Inlet manifold
ACL Bearings
ARP Studs
OBD1
Tuned on Crome

 

Depending on your altitude and weather conditions, you can probably expect a general range of 210-230whp. If my information is correct b16 pistons add compression, if you went with a port/ polished gsr head you'd get better all motor results due to the added compression and combustion chamber size.
