CRX Motor Debate ZC vs B16
 

I have a 1990 CRX Si and I am debating on which of these two motors to swap in. I like the zc because it is a direct bolt on and alot cheaper. But I like the vtec and extra power of the b16. The car is going to be a daily driver/weekend street racer. Any input you all have would be awesome, thanks!

Re: CRX Motor Debate ZC vs B16
 

A D15b7 would own both of those.

Re: CRX Motor Debate ZC vs B16
 

What's this now? I don't know anything about that motor... Is it a direct install or does it require a bunch of custom stuff liek the b16?

Re: CRX Motor Debate ZC vs B16
 

he was being sarcastic, a d15b7 is a junk pot sohc motor, if you never want to boost it, spend the money for a b16, if you plan to boost it, save your money and do a zc or better yet an Ls motor (b18a/b) because the Ls and zc motors have lower compression, so they'll be better for boost, plus when the motor blows up, it wont cost as much to replace, and im sure somebody will chime in and say a b16 is just as good for boost as a zc or Ls motor as long as you know what your doing and have a good tune, but bottom line is an Ls motor on boost is going to do better than a b16, and if anybody disagrees, bite me...

Re: CRX Motor Debate ZC vs B16
 

Funny, I have a bone stock D15B7 and so far I've had three faggot ass 99-00 Si owners with OMG BOLT ONS on their B16's ask me what I've done to my car to make it so fast - they couldn't pull on me.

Frankly, A6 or Z6 is going to own the ---- out of the high mileage crusty ass ZCs you get these days, and cable trans B16 are just as worthless on top of being *expensive*.


Set a damn power goal and a simple search will tell you how to get it bang-for-the-buck. Just guessing here, any D16 + boost or an LS + boost is going to be your answer.

Re: CRX Motor Debate ZC vs B16
 

LS+boost is my dream swap

Re: CRX Motor Debate ZC vs B16
 

I wasn't planning on boosting at all on this particular car, at least not for awhile. I'm becoming interested in the "mini-me" swaps, they seem to be a pretty good bang for your buck and easier to do swap/conversion.

Re: CRX Motor Debate ZC vs B16
 

I've got 2 friends with ED's.

One has a SOHC ZC aka A6 with boltons and the other has a B16. The ZC stays dead even with the B16 until the top end of about 3rd gear. We could probably throw a few more degrees of timing at it, but the car goes pretty good for a SOHC NA engine.

Oh, and I smoked an Integra tonight. :6

Re: CRX Motor Debate ZC vs B16
 

I'm goin with JD on this one. I've had more than a few z6 motors that have been just as fast as my OMG JDMB16 swap. After I nuked my LS/turbo I dropped in the b16 and honestly wasn't impressed with the results...no torque at all, no power really until after the 5k maddd vtecccc range, and for the price of one...---- that. My LS without the turbo felt faster because of the extra torque, and my LS at least got about 26mpg...the b16 i'm kinda lucky if I get around 18mpg on the highway, and around town maybe 12 :P

Re: CRX Motor Debate ZC vs B16
 

Okay so what is the actual difference between a D16Z6 and the D16Y8, I am interetsed in tehse 2 because they're VTECs. and I am not sure what is in my car, if it's a d16a6, like it should be, then I will just do a mini-me d16ya swap. If its a d15 I'll swap in one of the two d series vtecs I think...

Re: CRX Motor Debate ZC vs B16
 

Being interested in SOHC VTEC for performance is like someone telling you a vanilla air freshener will give you 50 whp - complete bullshit. Just get a D16. Any D16. For forced induction headflow is meaningless. For NA, A6 flows best... not that D series headflow means anything since you aren't getting any power worth having from a NA D series.

Re: CRX Motor Debate ZC vs B16
 

It just so happend I just finished my turbo set up on my LS.

Re: CRX Motor Debate ZC vs B16
 

B18A/B :y

Re: CRX Motor Debate ZC vs B16
 

I ------- hate LS motors, go with the B16 and build a nice bottom end for it.

To the original poster... Didn't you message me asking if I wanted to buy your CRX? That pic looks familiar.

Re: CRX Motor Debate ZC vs B16
 

I ------- hate you :7

Re: CRX Motor Debate ZC vs B16
 

haha, why no love for LS motors?

Re: CRX Motor Debate ZC vs B16
 

BBKA is a filthy V-tech lover.

Re: CRX Motor Debate ZC vs B16
 

I'd take a LS with like a hydro b16 tranny. What do you have in your car now that makes you want to swap to something else?

Re: CRX Motor Debate ZC vs B16
 

That might have been the guy I bought it from, but it wasn't me. I just got it last week.

The only reason I am not dropping in a B16 right now is the cost of the engine + mounts, shift linkage etc needed for it. Having a mortgage is annoying sometimes...

Re: CRX Motor Debate ZC vs B16
 

Just leave what have in it now and boost it.

Re: CRX Motor Debate ZC vs B16
 

If it still runs for whatever you have in there now. Just leave it until it blows. Why take it out? I don't get parachuters. If the plane ain't broken why jump out?

Re: CRX Motor Debate ZC vs B16
 

It does work, well besides need a new dizzy, so I will be doing just that. I am going to work on the suspension and bolt on stuff till I can afford a B series swap or the d16 in it gives.

Re: CRX Motor Debate ZC vs B16
 

stock D's dont take the Nog boost settings very well :3

Re: CRX Motor Debate ZC vs B16
 

me love zc!

Re: CRX Motor Debate ZC vs B16
 

If you find one for a good price; B16 FTW.
Mounts are dirt ------- cheap, stong bottom end, will punish an LS (stock for stock, on exact same setup). The only down side is you wont be able to pull on JD's b7 lol :P

If you want a cheap fun boosted car, boost ANY D.

Re: CRX Motor Debate ZC vs B16
 

Last time I checked HASport mounts, shift linkage, axles, and harness were like 1200-1300 all together... you must know somwthing I don't...?

Re: CRX Motor Debate ZC vs B16
 

---- anything hasport is gonna be a ------- billion dollars. Get some mounts and ---- off ebay.

Re: CRX Motor Debate ZC vs B16
 

i recently(within the past two months) picked up a b18a1 bareblock for free. im going to go with a ls plus boost. yes a b16 would be a ok motor in your crx if you are just goin to go NA, but if you boost a ls would be much better than any high cp NA b16. now if ya want some crazy ---- go ls/vtec, with boost. im just goin for ls plus the boost factor to get around 300-400 streetable horsepower. its your choice, do what ya want.

Re: CRX Motor Debate ZC vs B16
 

hasport mounts? this isnt 98'
ebay yo'

Re: CRX Motor Debate ZC vs B16
 

yeah ebay is cheaper, but is the ---- off there actually decent and viably usable? I knwo for a fact that HASport gear is gg, can't say the same about ebay...

My plans are NA (naturall aspirated?) B16 once I can afford it, I am new to street racing so not sure about boost etc...

Re: CRX Motor Debate ZC vs B16
 

A NA B16 is worthless.

2.0+ liters if you insist on high dollar low yield NA faggotry. Rob's old bottom end, 85.5X92mm, Carillo A-beams and Eagle crank, can be had for $2200 or you might talk the guy down a bit, needs ringed.

That's pretty much how you have to spend your money if you want a NA Honduh that's faster than a stock D16 with a T3...

Re: CRX Motor Debate ZC vs B16
 

lol... see this is how much a noob I am,. none of that made sense to me except B16 = crap. I just want a good performing engine that isn't going to run me like 4k or more...

Re: CRX Motor Debate ZC vs B16
 

How about what you have with $1500 of turbo ---- bolted to it?

Re: CRX Motor Debate ZC vs B16
 

Sounds like fun, though I'll have to do alot of reading I guess.. I know nothing about turbo at all. Can a D16a6 really reach power levels of the b series? I didn't think that was really possible.

Re: CRX Motor Debate ZC vs B16
 

an old piece of ---- 180k d16a6 no unless were talkin bilstering speeds of beat up 15 year jdm b16's



hasport is nice

if you look in the sticky in for sale we have a seller who sells the b stuff




Your best bet is read and look at threads. If this goes to well I like the gsr motor style thread Ill shot myself in the head

Re: CRX Motor Debate ZC vs B16
 

Last night the same SOHC ZC with bolt-ons I mentioned earlier kept even with a GSR swapped 93 hatch until 4th gear. I don't know what tranny combo he was running, but ricky racer nearly ---- his pants when the hood was popped for him after he didn't believe it was a stock SOHC engine.

Re: CRX Motor Debate ZC vs B16
 

Sigh...

Re: CRX Motor Debate ZC vs B16
 

:-*

Re: CRX Motor Debate ZC vs B16
 

d16a6 is a fun motor, if your looking for straight line speed then do the boosted LS but if you want a car that handles well and is fast, stick with an a6 or if vtec means that much a z6 with mild modifications and spend your money on other suspension work. i have a blast with my a6 and have spent money on suspension stuff(which is more rewarding to how i drive), a big motor has a lot of power but you add like a hundred pounds to the front of your car, thas just my 2 cents.
