Re: deck height of B20B???`` (tinkerbell)
The deck height of the B20b/z is pretty much the same as a B18C1. Acoording to CRVtec.com, the B18C1's height is 212.39 mm, and the B20b/z is 211.84 mm. The only difference is that the "giraffe neck" style intake manifold of the B20b is taller and won't fit under a stock hood. You can use an intake manifold from another B-series engine, such as the B16, B18C's, or B18's. As far as the B20z, the intake manifold is flush with the valve cover.

They're wrong. We checked and measured it one day when we were bored.... it's EXACTLY the same size/shape/dimensions/height as the B18A/B short block... same with the head, same **** people.
If the B20 block WAS almost as tall as a B18C block, wouldn't it make sense that it would need different length rods and possibly a different crank than what's in the B18A/B LS blocks? Fact of the matter is, the LS rods & crank are the exact same parts used in the B20B/Z motors (both US and JDM). Don't believe everything that you read on the internet... any person can write up a webpage and say that their info is the correct one.

Re: deck height of B20B???`` (daver)
how do you measure a 0.5mm difference in deck height anyway? thats pretty close; what do they measure with?
Say that to someone at Nasa or Boeing and they will cuff you upside the head.
0.5mm may not seem like much to the average Joe.. but 0.5mm can mean the different between someone seizing or running properly. 0.5mm off in a turbo prop engine could mean catastopic failure.
As for automobile engines, 0.5mm can mean a different of half a point in compression or more. Its a big deal. Don't underestimate it.

Re: deck height of B20B???`` (G3-TEG)
hey!
lets all chill!
i stopped relying on crvtec a while ago...
if it is only 'around' 7mm its all good.
thanks v. much,
t..
PS they meause it with very precise instruments designed to measure what ever it is that they are measuing...
blueprinting an engine is expensive because of the cost of the tools you use...
got any interesting tool pics G3-TEG?

hey hey, i'm sure Honda has precise and specifically designed tools for measuring stuff, but does the crvtec.com guy or Newman have them? Or do we just use a ruler.
When i said .5 mm was close, the above is what I meant, NOT that it was negligible.

We are talking tolerances on the order of 0.001" and sometimes even down to 0.0001" on an inch. The human eye can't not distinquish minute differences at that level.
There are special instruments that engineers and machinists use specifically for measure down to those tolerances. A few of them are (automotive related):
- caliper
- micrometer
- depth micrometer
- bore gauge
- depth micrometer
- machinists scale
Depending on the type, they can measure down to 0.001" to 0.0001"
An example of the depth mic is here:
I can provide more pics if necessary. I have a degree in Industrial Design/Engineering and used these tools on a daily basis on the job site, so I'm familiar with their function.

ya i have a dial caliper, but i can't imagine how to measure deck height with it. I was simply wondering how they measure deck height and i threw the "ruler" in as a joke.

.....yeah word.
all a B20 (US or JDM) block is, is an LS block with thicker sleeves, LS 1.8L crank and LS rods, but a wider diameter piston which in turn gets it up to 2L.
