Been looking into stroking my b16b but getting confused. I know what parts I need to do the job but I just need to know if I will need any other supporting mods like cams valves and springs ect. I'd also like to know people's opinions for changing the final drive on the s4c box. I'll be carrying out the work myself so any info/opinions are more than welcome
 
Just crank, rods. Needs a rebore most definately...so also pistons and rings.
The rest is the same.
Ecu of course.
 
Yeah just b18c crank and rods.

From what I've seen the spoon kit had a brand new crank, rods and Pistons from Honda plus a spoon head gasket. If you find the rods and crank and use your current b16b Pistons you will have high compression than a standard b18c I think. But as said above need some other standard rebuild work.

As for final drive, to put say a 4.7 in a s4c you need the final drive shaft, 1st gear, bearing and spacer. Not 100% sure but that is far as I know, hope this helps.

Why would it need a rebore most definately? :confused:

As far as i know a rebore is only necessary if the cylinders are damaged or mis shaped due to wear.

There will a lip where the shorter stroke stopped.
Doing this without a rebore would be possible only if that lip honed out within tolerance. I expect it would not.
 
Be wise to go oversize Pistons anyway.
As John says the lip left by the rings stopping at the bottom of the stroke can be quite large.
You'll want the best cylinder condition possible and a .5 oversize bore will allow that and you'll be able to set the perfect piston to cylinder wall clearance.
Just a hone is likely to leave a lip
Bore is likely to end up with more clearance than you need on the standard 81mm bore.
If you use the b16b piston you'll want to be careful which cams you use with them, although the compression is high the valve reliefs on the piston are shallow compared to a proper 12.5-1 cR piston.
Do it right, do it once.....
