Peak HP and Torque means nothing. That’s for the dyno junkies. The numbers that u guys are citing are peak numbers. What really matters is useable powerband.
IMO the powerband of the b20 is far more useable than the b16. U get max torque at around 3500 - 4000 rpm’s rather than 6500 or whatever it is.
The b20z is a definitely quick. I think for the G2’s this is a better option. A long block will run u about US$1000 with new water pump and timing belt. U can utilize the G2’s ECU no problem. It’ll run good. WE just did a swap in a friend’s G2 and it’s fast. (Faster than a 6gen hb with the same b20 block ) For some odd reason the b20 seems to rev a lot quicker than the old LS motor. We haven’t found a conclusion for this yet.
So true… usable powerband is all ! not Peak numbers…
B20 as torque from 1000 rpm all the way to redline which b16 is far from having … but b16 makes more hp in in stock form, now, add agressive cams ( something along the Crower 404 ) to the B20 (especially the B20Z) and you’ll tear appart the b16a in less time it takes for me to write this sentence…
Well i’m sold to non-vtec, but in conclusion, i really think both engines are good platform to work with
I want a b20 swap! i know a guy who has a stock b2o with rs tranny and rs cams he runs a 1/4mile @14.81 in an 2g teg with a skirt kit in the fron a system and 16s!
Well fellas, You all have good points and bad points. I had a B20Z in my integ and I was pretty happy with it myself. I now have a B16B in my integ and i assure you Vtec is very fun and high end my integ rolls. Looking at my 1/4 times I noticed the B16 was faster. I also have Itr/Ctr cams so really its not fair too compare. Anyways I think there a pretty close race though. i am currently building my B20Z bottom end and I am going “B20-Vtec” which is both worlds. In my opinion B20-Vtec is the best way too go fellas. Thats my opinion though and everyone will have there own judgements. I personally rolled in a B20 Vtec and it was awesome.
The B16b is the little brother of the B18c5… The B20Z in stock form don’t stand a chance beside the B16B
Let’s compare only the b16a to the B20B or Z…
My opinion: B16a is equal to the B20Z in the quarter in their stock form, but the B20Z has more potential due to it being 2.0 liter, you can easily make hp, but you can’t make displacement ( Torque ) In my opinion the B20Z is a better choice because you have the displacement, then you add Crower 404 cams and you get higher lift and duration than a Vtec motor, Furthermore there’s no engagement point, those cam are always on the overlift, so no worry about not being in the VTEC like in VTEC motors… it’s powerfull from 2000 rpm to 8000 plus you have the torque to help, which the b16a is far from having … The b16a is just cooler to run around because VTEC engagement looks cool and sound great, but is not as powerfull as people think: I’ve seen people thinking that when VTEC kicks in, it will make you lost traction all over and possibly lost control and make an accident… Even with Toda cams ( more agressive VTEC cams ), you will feel VTEC like crazy but not that crazy !
I rode in a 97 (i think) civic coupe with a b16a last night. I was disappointed. I thought it was pretty slow to tell the truth. Yeah, vtec sounds great and it sorta kinda had pull in vtec, but he barely won against my cousins ls and that was only b/c my cousin couldnt get traction on the gravel road. I’d think that the b16 in a teg (heavier than civic) would be even slower than the civic :whoa: I’m definetly not going the b16 way in my tegy.
“”“You are wrong.
Its not an opinion,it a fact. LS/b20 revs like a tractor compared to b16.”""
Well, i personaly think YOU are wrong…
My slow ass B20z rev to 8000 rpm with only a block guard, ARP rod bolt and head stud… i made 152WHP and 131WTQ with only bolt ons… and a constant 14.7 on the Gtech competition. All this in a 4 doors 90 integra ! and i raced a couple B16a CRX… they just can’t hang with the b20…
I’ll have the crower404 camshaft breaked in in about 2 weeks…i’ll retry the 1/4mile and the Gtech dyno… i’m pretty sure i can do very low 14" if not high 13"
and it pull’s as hell from 3000rpm to 7200rpm…(for now) 8000 rpm redline with the cams
No waiting for vtec to comes in ! it pulls wheter you are at 3000 or 7000 !
its all about power to weight ratio…i have a B16A in my 89 G1integra…my car a little lighter than a G2 so i know its a little quicker…but fact of the matter is that torque is what gets you going and HP is what keeps you going…remember HP is a product of torque…everything is relative…it all depends on how much money you have and how fast you want to go…too many variables here to argue about. you want torque? ill give you a ride in my truck with a 427 big block and 500 Lbs/FT of torque… I myself love the VTec technology and revving these little guys. all a matter of opinion and depends on what vehicle each is installed in…just my .02 cents
ok well lets take this a little farther… what if u had a skunk2 intake on a b20 with an S1 transmission and all the basic bolt ons we are all driving around with (i dont think there are that many of us rolling around with less than a short ram or plug wires, no one i know is BONE STOCK) vs say a b16 with a skunk2 intake and the same tranny. how would a race between these two cars go? stock cams but maybe cam gear tuning included.
how much of a diet would a G2 need to be on before the b16a was no longer a torqueless burden. hatches are around 2000 and our cars like 2600? im sure im down to at least 2500 by now, if i go much further, down to 2400 am i still gonna be plagued by the lack of torque or will i be pretty happy? those of you with G2s and b16s that are actually pretty fast, what did it take, and how light are you?
What I’d like to see is the same guy run both set ups at a track…one after the other, three times each and then compare times…I have a B16 and want more torque, which is why I am stockpiling parts for my 84mm sleeved LSVTEC…on one note, I don’t know about you guys but I wouldn’t want to use the tranny from my B16 w/a B20 or a CRVTEC…I’m doing 4,800 rpm’s on the highway at 80mph!!! When you include the longer stroke of the B18 and/or the B20 I don’t know how reliable it would be over a long period of time…maybe that’s an idea for another thread? Anyway back to the issue at hand, I own a B16, but I think the B20 could probably beat me…
sighs do a poor mans itr. A ls/vtec with the same mods MIGHT be a little faster…but you’ll be must more reliable for $$. Apparently the b16 has no torque and the b20 does not have a lot of hp(i’m not talking about a 404 cammed, 12+cpr b20 either). -btw consider weight reduction- especially the b16 guys.
[QUOTE=BoyRaCeRs;23603]I was wondering which one swaped stock into our cars would run faster? b16= horsepower : b20 = torque???
I’m thinking the b20?[/QUOTE]
I beat an rsx type s with my bolt-on b20b gsr tranny. Can a stock b16 do that? No.
Throw a b16 tranny to my b20b and,… Well you know what will happen. FAST!
And no to every one who says stock b16 beat stock b20 on 1/4 miles. They think just because of top end… But do they really know when their “top end” comes??? When I’m turning back around getting in line!!!
To all b16 owners and fans. Don’t be mad that a $500 motor whoops your butt. Your just defending because it cost you.
I myself love the VTec technology and revving these little guys. all a matter of opinion and depends on what vehicle each is installed in…just my .02 cents
