im new to this forum and couldnt really find any info on B16A head with a B18C1 bottom end. could anyone tell me if its worth it?, what are the power gains?, track times?. i have the B16a in my EG
and im not really happy with it cuz there is no low end power.
any info would be great

thanks

id say screw the b18c1 bottom which has a 81mm bore go with a b20 bottom end which is dirt cheap and has a 84 mm bore. i did a b16 head with b20b bottom and pulled approx 168hp and 130fp of torque. its a big difference than a stock b16.

b18c1 block + b16a head = poor man's type r.....i believe my rdm buddy (bryce) have this setup...ask him for opinions

not a big power increase but your whole powerbadn will be beefier

only issue is your compression drops to probobly under 10:1

so get soem p30 (b16) pistons for the b18c block and your set...then soem cams and your rolling

still wont be much gain with a b18c block. youll be better off with a b20b. no replacement for displacment.

My last motor was a b16a head on a gsr block with an ls crank. The setup work extremely well. The great thing about the gsr block is it still retains the oil squirters that cool the skirts of the pistons for high rpm use. The b18a/b and the b20a/z lack these oil squirters.

I say go for it.....

ha, what about the other way around? a b16 block with a gsr head... i bet it wouldn't make much power, but i wonder how its powerband would be.

about the same....abit more compression with abit better cams
