The first modifications of the B20B engine had the compression ratio of 8.8 and the power of 126 HP @ 5,400 rpm, and the torque was 180 Nm @ 4,800 rpm. In 1999 production of the B20Z series was launched, which had a new intake manifold, intake camshaft, increased compression ratio (CR = 9.6), a different oil pump, and an ECU. Dec 15, 2010 · The b20b low compression is the same as the b20b4, b20b high compression is same as b20z. And the compression on the b20z n b20b high compression is 9.6:1, I think...yeah. pisceslxix69 You must log in or register to reply here. Feb 05, 2012 · P8R B20s are equipped with lower compression (8.8:1), most of them came on the Orthia (JDM car) and were supposedly on only 1% of all b20's. Not sure I really belive that numer but whatever. I have had both the high compression and the low comprssion b20's and I couldn't tell a difference in my butt dyno between the 2 haha.

P3F means low compression 8.8:1, vs the PHK pistons at 9.6:1. These simply will not do! The cylinder walls all looked to be in great shape, no scoring and visible hash marks throughout. Overall the bottom end looked great. The bearings even looked like they had the original friction material intact.
To get compression that high, you'll have to use the stroker crank. (or heads with a really small combustion chamber) Yeah I ran the numbers through one of those compression calculators a while back and came up with like -3 or -4cc dish volume for a 3.4 stroke / 3.840 bore. Pretty much a... Aug 03, 2008 · Low-Level Compression Low-Level Compression can be explained in simple terms as it does exactly the opposite as a High-Level Compressor. A Low-Level Compressor will upwards compress the gain when the level falls below the set threshold resulting in an increase in gain or in other words a distressor. Jun 05, 2007 · High speed compression is designed to allow the oil to flow, not restrict it. That is what your low speed settings are for. Everyone has this image of minimal low speed compression being what makes the suspension feel smooth at high speeds. At high speeds, your low speed compression isn't making any real difference in the shock absorbing impacts.

Higher compression would be nice, I might rebuild the bottom block. u should turbo it also that would be badass Honda B20B engine reliability, problems and repair. The amount of power and torque these engines make are a good fit for Front4 minimum weight rules for Integras, but lighter cars (Civics, CRX) may have to add a substantial amount of ...
Mar 09, 2011 · Cam timing plays into it as well. A cam with monster duration will bleed off some of the compression and allow you to run a higher compression ratio. Bore size also plays a role. The bigger the bore the further the flame front has to travel from the spark plug and the higher the chance for detonation. Quench area is important too. Jun 06, 2012 · The lower the compression the more boost the car can handle right? So here is my question, if i was to buy a B20B/Z which has 133 lb tq with 8.8:1/9.2:1/9.6:1 which is pretty low, so if i was about to put a Vtec head from let say B16A or B18C, can i boost this motor that im gonna get with high boost because of the low compression pistons.

B16 vs b20 Integra Civic CR-V B16A B18C B20B Engines - J-Spec Auto Honda reintroduced the B20B and B20Z in the first-generation Honda CR-V (1996). This generation of the B20B and B20Z was designed more similar to the B16/B18 family, and to the enthusiasts’ development of the B20/VTEC engine. The first modifications of the B20B engine had the compression ratio of 8.8 and the power of 126 HP @ 5,400 rpm, and the torque was 180 Nm @ 4,800 rpm. In 1999 production of the B20Z series was launched, which had a new intake manifold, intake camshaft, increased compression ratio (CR = 9.6), a different oil pump, and an ECU. The lower compression B20B is more desirable for a bolt on supercharger or turbocharger kit because of this. If you wanted to run high compression with a B20B/Z there are no factory pistons that can do this, but any number of quality custom forged piston makers, such as JE, Aires or Wiseco can make a piston for the B20B/Z.
