Default b16 vs b20

So have been thinking and reading alot on here and other pages. I have come to see that the b16 is over rated and lacks any real power. Then there is the b20 which obvioulsy has way more low end power then the b16. Sadly I dont plan on doing anything wild with my motor as i will rebuild my turbo saturn when the civic is running.

so with a 4-1 header, aem v2 intake, hks cat back, high flow cat, safc(or vafc) tune, and maybe intake mani and cams. Which of the two motors would you pick?

I may be a little biased though as I love torque and I don't care much for VTEC and B16's are too overplayed for me.

About that turbo Saturn though, are you on saturnfans?

B20 needs a VTEC head or else have fun redlining at 6000rpm.

I'd take a B16 over a B20.

If you're not happy, at least you'll have a VTEC head. B20 or even B18 blocks are pretty cheap.

B20 for the low to mid range torque. with the right setup they are pretty quick.

What, sir, have you been smoking? It must be really good stuff.

There's no doubt about it that a stock B16 in a Civic/CRX chassis is going to drive circles around a B20 all day and all night long.

What would make you think that a B20 would be any faster than a B16?

And what's with all the B16 hate lately? Is a GSR really all that much better because it has 10 more HP and 10 more ft/lbs tq? I don't think so. For the price you pay, dollar for dollar you can't beat a B16 unless you put the $2000 you might spend on swapping a B16 in the Honda-Tech way into the stock D-Series motor for a turbo setup.

Let's say you do swap in a B20. Where do you go from there? There's only so much those sleeves can handle boost or N/A. Not to mention the head is worthless.

Now let's say you swap in a B16. Where do you go from there? You've got a good head now, and the block is strong too. You can push upwards of 250whp on boost and as much N/A power as you can throw at the stock sleeves without even having to worry about it.

And if you really feel like you need that extra little displacement...that's fine, you can swap the block out for an LS block or if you're feeling like a baller you can get 84mm sleeves installed, and then the sky is the limit.

b20vtec is way better than a b16. my boss has a b20 vtec in his em1 and he's running 12.9 n/a. do that with a b16 all motor that's still street legal. but b16's are nice too. they're easier to get going. but if you're modding heavily.. then go b20/ls/vtec

I LOVE MY B16A!!! I dont know why people bitch and say it's not fast.....It's not torquey like everyone says because it's a high rev engine....It's real power is in the upper RPM range. It's not a good drag engine......But for like road courses and such it's so awesome. I love it......

ok sounds all good with me guys! I will just stick with the b16 i have almost ready to drop in. Only reason I was thinking b20 is because I mostly autocross and figured the extra low end might help but i have always heard the b16 is great for road racing.

buy the b16! its the best bang for the buck. i took forever deciding which engine to buy and i went with the b16 because its an overall strong engine and can handle lots of hp! throw a b20 block under it and you got gobs of torque with high revs and not to mention the ever so loved V-TECH!!! (praise the lord for v-tech) Oh and speaking of strength did any of you catch the backissue of hci magazine? uh 507 HP on a stock b16 block!!!!!! 24lbs of boost!! HOLY S*&T!!! thats strength. no sleeves no boring just replaced the pistons and rods. that should be a seller for ya

B16a all the way. the best engine to turbocharge due to its perfect rod to stroke ratio! all motor guys want larger displacement. But other than that this debate will go on forever.

Both engines are cool, but the B16A is a better choice. Stock they are similar in performance but with very different power bands. The B16 in stock trim is mild, but has much higher potential.
Here are some things to keep in mind about the B16A:

- optimum rod to stock ratio
- stronger block with more webbing
- superior oil and water pump
- superior flowing head

i say b20 unless u have tons of cash to throw into the b16 right of the bat. To me a stock b16 feels like a single cam til 5,000 rpms...after that vtec hits pretty nice though...

who in their right mind would even concider chosing a 1.6 over a 2.0 liter. People that have B16s think they have everything when really they got their d series bottom end with a dohctop end w/ vtec and get 160 hp and 118 ft.lbs. of torque! Now if your gonna put the B16 head on the B20 now we're talkn.
