I have a real fun idea for that b16a i have in my garage. Me being "Mr. OEM Honda", I would love to make that thing an OEM stroker motor, using all/95% OEM parts in the block.

<FONT SIZE="2">CRANK</FONT>
I'd use b17a crank & rods. I'd send the crank out to Laskey Racing to have them Balance/Micropolish it (cost = $150 includ. return shipping).
Why You Ask??
-the b17a crank changes the 77.40mm B16A stroke to 81.40mm
-this changes the B16A displacement from 1595cc to 1678cc
-you need to use B17A rods (rod length = 132.00mm) to keep the piston-deck height correct (unless you want custom rods).


<FONT SIZE="2">PISTONS</FONT>
Here's the estimated results of using different OEM pistons with the above crank setup:
(NOTE: 100% stock USA b16a (also 1st gen JDM b16) compression=10.2, Japan '2nd Gen' b16a=10.4)

-USA b16a pistons: compression=10.76 (about 10.8), piston-deck height =0.022inches (stock b16a/b17a height)
-Japan b16a pistons: compression=10.97 (so about 11.0), piston-deck height =0.022inches
-USA integra-R pistons: compression=10.50, piston-deck height =0.013inches
-Japan integra-R pistons: compression=11.02, piston-deck height =0.013inches

Reference Piston-deck height #s:
-ALL integra-R: 0.026 inches
-ALL GSR: 0.034 inches
-ALL b16a: 0.022 inches

Personally, i was thinking about using the Japan integra-R pistons i have. But after researching/ calculating all the #'s, i think staying with the Japan b16a pistons will be best (NOTE: my b16a is Japan-spec). The Japan b16a pistons still yield a decent compression of 10.97 (so about 11.0), while keeping the piston-to-deck height at the stock setting. This is perfect since this will be a 95% daily driver, so i want this to be as reliable as possible.


<FONT SIZE="2">HEAD</FONT>
Maybe a stock type-R head? Or have the b16a head port-&-polished with a valve job (cost-wise, im guessing they'd be about the same). Maybe i should just use my stock GSR head, or maybe i will use the port-n-polished GSR head i have.

Since i would probably use the Japan b16a pistons, here are some ESTIMATED #'s using b16a/type-r and GSR heads:
(NOTE: #'s are based on stock heads do not take into account port & polish, flat-bottom valves, etc.)

-B16a/Type-R head: compression = 10.97
-GSR head: compression = 11.24

Based upon these #'s, I would more than likely just stick with the stock B16A head.

HOWEVER,
i would probably go with the Port-n-polished GSR head i have, if i felt like spending the money on it.
[NOTE: this head is bare right now (i have Omni valve springs/retainers),
i would buy Omni flat-bottom valves (to bump up comp. a little more, and so i can leave my stock GSR head stock incase i need to use it)
and i would need to get the head assembled]


<FONT SIZE="2">OTHER STUFF</FONT>
At this point, i do not know what cams i would use. Probably just stick with the B16A cams. But Stage 1/2 cams would most likely be the best choice.
In the tuning of this motor, i would rather have it tuned for RELIABILITY rather than HP.

<FONT SIZE="2">But again, At this point this is all JUST AN IDEA! If i decided to spend the $$$ building-up a motor, i would probably just build up my GSR</FONT> (or i would research the cost of each, and see which build would be more worth it, using the same amount of $$$ on each build).

is this really worth the money if you would like to go cross country. or is it better to go B18c1 or b18b for that. i just want somthing relieble (i know its up to the tunning to do that but..) and strong to win.

That's where each individual comes into play. What might be good for person A, might not necessarily be optimum for person B. It all comes down to the simple element of choice.

id do a lot of reading/research and make sure you know what you're going to be doing with your car. People need to do alot of research and understand when they buy a product, dont just go on specs and the price to determine if it's worth buying. Don't buy a product because it's top-of-the-line or JDM. Buy the product that is BEST SUITED for your specific build.

All i am trying to do is provide help and insight to others through my research
