hey guys right now i got a d16z7 (97 Si)
i was just wondering what swap could i do for a good price i know that the b16A would probably be the best
but is there anything cheaper that would give me more Horsepower than what i have now
and i would like to stick with something with VTEC
good u please list the motor and maybe a price thanks
or if it is better in the long run just to save up and go with the B16A
thanks

if really want to get some HP then get the 1.8L non vtec and get custom turbo and that thing will smoke so many cars

otherwise B16A is the best choice for your car in my opinion

HEADTRNR

what motor is the 1.8 is that the integra ls

niteridr, if that's your car in your sig. that looks really nice! I love the colour! Very nice setup! Sorry I don't have any suggestions for on the motor since I'm no expert! I'll leave that up to everyone else to argue! I think if you decide what you are going to do to it (turbo or N/A) then I would really do your homework and find out which motor would be best!
Good luck and do come out to one of the meets so we can see that sick ride!

Ya that car is NASTY. SICK. LIKE WOW> ...
Go for H22 - b18 lots of power. Youll need it that car looks heavy.

2nd gen b16! there is soooo much you can do and its a strong runner

HEADTRNR

thanks guys
i wish that was my car
that is pretty much the same set up that i want to do
the paint job is so sick
anway thanks

jus get a straight B20 block and drop it in

Then that leaves you option to think about whether you want FI or NA (two paths which the B20 can make mad amounts of power)

HEADTRNR

how do i drop in a b20 block what engine is that from
and what is NA and FI
how much power would i gain if i dropped in a b20 block just by itself
and how much would it cost
also how much would the swap for the B18B1 cost me

ryuujin

a B20 is a CRV engine, it's pretty much a 1.8 block but it's got different internals.

NA = Naturally Aspirated/Normally Aspirated/All motor
FI = Forced Induction(turbo, supercharger, NOS)

As for how much it'll cost? For the B20 longblock, it'll run roughly $1100 - $1300 I'm guessing. To make it work, you'll need either a Teg tranny (any model will do, but figuring out what you want to happen in the future will help too) or an SiR tranny. I'm not so sure about the ECU but you're probably gonna get some sort of tuned ECU. You'll probably need a new intake manifold (once again SiR or Teg ones will do, except GSR I'm thinking), as the stock intake manifold on the B20 will be too high and will cause hood clearance issues.

The numbers? A straight B20 will give you around 146hp & 133lb ft. of torque (provided it's a B20Z). A B20B will give you 126hp & 133lb ft. of torque. Either way, you'll love the torque on this monster

Though it's not a high revving motor, having 2000cc will definetely give you the edge right off the line and it'll haul a Civic body pretty damn quick

So torque up first, then decide which route you want to take, FI or NA. FI involves turbo/super/NOS etc., while NA will require that you obtain a VTEC head(though not ABSOLUTELY necessary). With the NA buildup it gets a little more complicated, BUT fear not, we will soon have an article up regarding this topic

Meanwhile do a little research around the web first about the B20 build up. Places to go would include www.crvtec.com and www.b20vtec.com

good luck, and enjoy!

This is what I know at least to my knowledge, those tech gods and motorheads, please add to my post if I've gotten something wrong, or something else to consider thanks

I've got waaaaaaay too many smilies in this post... hahaha

HEADTRNR

thanks bro
so if i get the straight B20 then can i throw on a b16A2 head
because won't that give me vtec just wondering
what if i get the B16A2 and then throw in an ITR tranny and ITR intake manifold will that give me good power
but if i do get the straight b20 with the b16a2 head will that give me good power with torque
and won't that make me AWD instead of front wheel
or can i do the b18b1 with a different head say gsr or ITR
just wondering what does changing the head do
is the head the part that says DOCH VtEC honda motoring
on the top
thanks

ryuujin

nah, putting in the B20 block won't give you AWD you wish hehehe

you could definetely slap on any vtec head, some are better flowing than others apparently. I'm not sure which one is best, but I hear it's something like B17 (when ported and polished), B18C, B16A, but I'm not 100% sure on this. B20vtec involves the B20 shortblock and a vtec head of your choice, but like I said, the B20 wasn't designed from factory to handle high revs, so what you'll need to do is basically blueprint the motor and give it some REAL bad *** goodies to re-inforce the block and the internals so that it can actually handle all the power that it's going to push out (if you don't prep the motor well, you could run into alot of problems e.g. blowing a hole through the block just as an extreme case, but of course that could happen to any block).

Well, getting a B16A2 or B16A with an ITR tranny + ITR manifold will be cool, but it definetely won't be optimal since the ports on the ITR manifold are bigger than a stock B16A, you cams (B16A cams) won't be able to utilize the extra air, so if you opt for that setup, go get the complete ITR valvetrain to back up the ITR manifold + bigger throttle body.

what you said about using a B18B1 or B18A with a ITR head is basically what is called a "Poor Man's Type R". Essentially you're building up your own Type R motor because it's 1800cc block with a vtec head. 1800cc block with GSR head? Well that's just a GSR motor then isn't it? But people do call those LS/VTEC's and likewise the process of building one is quite similar to the B20vtec so you'll need quite a bit of prep work (not to mention ALOT of cash, if you want it revving safely, and pushing good hp numbers )

Changing the head in most Honda DOHC cases basically mean getting VTEC, at least, alot of people I've read about do that

What's VTEC? Someone else can tell you, but the cams in a VTEC head differ from a non-vtec DOHC

Actually if you were to rip apart a B18B1 and a B20B/Z and exmaine the individual parts, you'll notice they are pretty much the same motor... only differences are the pistons because of bore size (B20 84mm - B18B - 81 mm) and the B20 cylinder walls are much thicker... everything else is the same. Rods, crank, head, valvetrain, etc. etc. are all the same.

Jugglez

i've seen both ripped apart so i can speak from experience.

ryuujin

I know damnit, when's T.O Teg gonna send you "the" file?

HEADTRNR

is there any way to slap on a different head on my d16y7
if not i think i will go with the b20 block with b16a head
or just the straight b16a2 swap thanks guys
which one will give me more power
i know the b20 will give me better torque and is that better in the long run

ryuujin

there is a way to modify the Y7 ...but that's just another SOHC with VTEC...doesn't produce THAT much more.

b20vtec (b20 block with any vtec head) will obviously give you the most gains, but it involves alot of time and money to make it run well.

B16A is just a straight drop and you won't have to worry really that much about long downtime, at the same time it gives the choice of upgrading to a B20 block in the future...

HEADTRNR

thanks bro
i think i will go with the b16a2 swap
thanks for all your help

ryuujin

anytime, anymore questions though I would've give you a

hahaha j/k

good luck!
