I have searched tons of threads and read through endless posts about the b16a2 or just the b16a in general. Most of them just tell the poster to get a b18c1 or c5. I know many people have gone from the d16z6 to a b16a2 in an EH (94 Si to be specific). Is this a night and day difference? I want a motor, something for daily driving, something heavily supported by the aftermarket, and something that is not too expensive. I can get the whole swap for $2300 so i decided i want this. But i just want to know if it is going to be a night and day difference. Sorry for the cliche "night and day" but you know what I mean.

Yes, the D16 and the B16 will be a "night and day" difference, but as far as your comment on the B16....people saying to go to the B18....I don't really know about that one. Those motors are fairly close to one another. A lot closer than the D16 (sohc 125hp) and the B16 (dohc 160hp)

Yea, plus add to that, the b16a2 I am planning on getting is a JDM one and is elegadly rated at 170hp, exactly the same as the USDM b18c1. But of course their is also the torque factor But hey......what can ya do

Doctor CorteZ

um , torque ?

it IS worth it to have a 1.8 GS-R/ITR torque advantage , B16 is fun but it gets old quick.

nsxmatt

It is a night and day difference. Very good motor for the money. It may seem the same just driving around town but once you stay in it and go through the gears you'll feel the difference.

jdmsol

All I was saying was that more people would swap from a D16 to a B16 then a B16 to a B18.

nsxmatt

No matter what the subject is if anyone says anything about a B16 someone always has to say B18's are better. This was not the subject. He was asking the difference between a z6 and B16.

Doctor CorteZ

and he said everyone is giving him B18 advice , which is the best route

why buy a B16 then have to upgrade later , when you can take an extra grand and do it right the first time.

Vanilla4215

Because maybe you don't have an extra grand to buy that b18.

B18C5-EH2

Hey man I'm sorry I didn't get back to you on the phone - your number was on my desktop and then my PC froze up before I got to save it.

As far as the difference, why not come out to my area and drive my fiancee's 1992 Si hatch with B16A2 swap? You can drive it and see the real difference if you'd like.

I'm not too far from you. E-Mail would be a good way to set something like up.

Doctor CorteZ

well I'm suggesting to wait.
I wish I would've.........

nsxmatt

I used the extra $1200 price difference to buy a exhaust, header, intake, coilovers, and used wheels. Plus i'm getting virtually the same times as people with gsr swaps. Like he said, he's interested in the B16 NOT the B18c.

94si94cx

Thanks for replying Tom. Thats cool about not calling back, but I will e-mail you about the whole engine deal. I definetely plan on going through you guys.

Ok, I would love to spend the extra $1200+ for the b18c but like someone posted, I could use that extra money for other things. Right now, I just want something faster than my crappy d16z6. I know alot of people that love this engine Nothing wrong with it, just need something a little faster. My car does need some work done as far as appearances go, like getting wheels (I'm rolling on steelies), finding the 2 pieces of moldings I'm missing from the passenger's side, and getting some factory sideskirts. I am also eventually going to get the body back to perfect condition and get it repainted the factory black color (It's black, just dull and crappy). Thanks for the help so far guys, keep the replies coming.

off topic but why dont you boost your d16z6

i went from a d16z6 to a b16a
to me the b16a feels like the d16z6 until vtec hits
b16a really lacks power in the lower rpm range

when you say the b16a and b18c1 have the 170 hp
thats true, but the torqe makes all the difernce
my friends gsr powered dx pulled much harder than my b16a w/ IHE

if your d series motor is in good shape id just boost it
greddys kit is only 1500 (sure its bare bones but it works)

94si94cx

Boost is an obvious solution to my "need more power" problem, but my engine has 150k miles on it. I know Honda motors are some of the most reliable engines in the world, but 150k is 150k. My tranny grinds going in to 2nd if i shift above 6K rpms. I would definetely want a new transmission, and if I'm going to do that, i figured I might as well just go ahead and get a new motor/ecu/axles while I'm at it.

I have a Z6 in my car, and driven hatches and coupes with B16's, and to tell you the truth, I wasn't $2,300 impressed. Sure, it pulled harder on the top end and better gearing, but I couldn;'t see myself spending that kind of money. I have raced plenty of B16 swapped hatches, coupes, and sedans. And have only lost about 1/2 the time, and that's at the most of 1/2 a car between my nose and their tail in the 1/4. I would suggest build the D16 and boost. cost you about the same, and turbos are quite addicting. The b16 and d16z6 both have 108 ft lbs tq, correct me if I'm wrong.

...rohit

Emerica....just curious whats your setup? and you got a Si hatch?

gleinz

Can I get your D16z6?

lazy bum shaughn

I honestly dont see how there can be a night and day difference, if torque numbers are basically the same. Sure there is better top end and all but still. Remember you get what you pay for, so waiting longer for a better motor is worth it.
Honestly, I'd save for an H22, but that's a little extreme since you want a motor now.

My old 92 Civic DX
I/H/E w/93 del sol d16z6 engine/tranny, centerforce clutch, field vtec controller.
Ran 15.3 @ 90 mph



My new 92 Civic VX
I/H/E w/stock jdm b16
14.4 @ 97mph

I've owned both and can tell you that there is a huge difference in the two. The B16 is better in all areas compared to the z6. Passing power is 10 times better, gears in the tranny are much better suited to the engine, even around town the extra power is felt. True the TQ between the two engines are almost the same but you gotta remember your also comparing 125 to 170hp.
You can't base a opnion on races with other kids with unknown driving skills. The z6 is a fine engine but it will not beat the same car with a B16.

rurkster

plus the feeling of vtech is priceless yo

del_sol

I got a d16z6 del sol, i run a 15.5, i beat si's all the time...wouldn't say its gonna be a night and day difference, but you'll feel it..

jdmsol

Yeah, I've got the D16Z6 in my sol too and best time for me is a 15.2, but I don't think I'll get it any quicker without a swap or turbo/supercharger. I'm satisfyed with it for now, but it's an addiction that one day will need to be given in to.

94si94cx

My way of thinking of it now after reading tons of threads is "A built b16 is going to be better than a built d16z6", but then of course this can also be applied to a b18c is going to be better than a b16, and a b18c5 is going to be better than a b18c1, etc..... I guess it's just what you can afford and are willing to settle on. Keeping the d16z6 is not really an option, I am just trying to find out if there is going to be a big difference in feel and power when I swap my stock engine for the b16a2. I think I trust nsxmatt, not just because he has NSX in his name but also because he did post examples of his cars and showed us that he owned both.

Evs-One

You're deffinately true here. That's why it is in your best interest, if you're willing to spend the money, to get the B16. I mean, you can swap in ITR cams, ITR tranny, 2 cams- so adjusting possiblities are a plus.
Those who want my setup- I'll say this first, I beat a Del Sol DOHC with 50K on it by 1/2 car, lost 1/2 car to 98 EX Greddy Turboed at 14 psi, lost 1/2 car to 95 EX coupe with B16 and 50 shot(hope he wasn't spraying, he got mad cause he barely beat me and wouldn't talk ). And was tied in quarter to my friends B16'd sedan, with I/E/H.
I'm running a ZEX street/strip cam, port/polished head, I/E, MSD ignition, ported intake manifold, LS throttle body, stock clutch, AEM cam gear, milled head, 3 angle valve job, etc. I need a header and some dyno time for my cam gear. And I got Crower valve springs, Skunk 2 retainers, and an ECU just chillin.
