can someone give me all the specs on these motors i was going to go b18c5 but what are the advantages?

 

»Engine Code: B18C (GSR)
»Year: 94+
»Valve train: DOHC, VTEC, 16 Valve
»Transmission: Hydraulic
»Displacement: 1.8L
»Horsepower: 185HP
»Torque: -
»Compression: -

»Engine Code: B18C (TYPE-R)
»Year: 96-98
»Valve train: DOHC, VTEC, 16 Valve
»Transmission: Hydraulic
»Displacement:1.8L
»Horsepower: 200HP
»Torque: -
»Compression: -

The B18C5 is basically just a B18C1 with a B16 head.

 

and thats that. Well done CRX this should be now closed, and used for future archive reference.









THE END.

 

That's not the half of it. Haha, yeah, right. I could write a few paragraphs about what hasn't been included yet. I'll keep it basic:

The C5 has higher domed pistons which bump up the compression enough to still yeild a well higher compression then the B18C1, despite the smaller combustion chamber in the P72 head. The camshafts have a slightly more agressive profile to them, along with upgraded valve springs to prevent float. The B18C5 PR3 head received a very light port job, also helping overall flow. The C5 is given a fat, short runner intake manifold vs. the C1's dual stage inverted manifold, and the ITR also uses a slightly different exhaust manifold. I've also heard from a few sources that the B18C5 oil pump and timing belts are different.

 

what exactly is float? And if the pistons are domed out don't you lose a little displacement?

 

Valve float, it's when the valvev springs are not strong enough to close the valve before the piston comes back again. The valve kindof "floats" there for a fraction of a second, and with high lift cams at high RPM, the piston will go down and back up again so fast it will hit the floating valve. Needless to say, that is bad.

Displacement loss isn't significant enough to impact the power output of the engine, while the increase the high comp pistons give will be.

 

yeah and when the valves float they also slam back down hard making damage even if they dont hit the pistons.

 

wow, that is pretty bad. I spent like an hour reading all about how engines work on howstuffworks.com and now I have all these questions about how upgrading all the head internals works and the benefits.
