1990 CRX. Yay.
Welll, tomorrow morning I'm going to pick up a nice 1990 CRX. 190k miles. Body is PERFECT. Adult Owned. Interior is completely stock, nothing missing, no stains, no tears. This guy was a perfectionist. He's selling it to me for 1300. He doesn't want it riced out and he says he trusts it in my hands. Sounds good to me.
I guess I just want to say what's up, because I'll definitely be in these forums a lot more now.
I figure the first thing I'll be doing is dropping a D16 into it, Should I just go SOHC, or should I go with the DOHC? There's no difference in power is there? And which would be easiest?

Well according to his sig.....he already has one in his current car. So he could just swap that and get a vtec subharness.....

Well I plan on just ordering another SOHC Vtec from HMotors.. Does the DOHC not come with a VTEC head or what's the deal on these? I don't know much about them.

Re: 1990 CRX. Yay. (xfletcherxx)
The non vtec motors are pretty much these (DOHC): DOHC ZC, B18a/b, b20....
The Vtec ones are pretty much these:b16,b18c,k20.
Almost all the dohc have more power than the sohc.

Re: 1990 CRX. Yay. (crx2nr822)
A SOHC ZC VTEC will give you about the same amount of power as a DOHC ZC non VTEC, which is ~130hp. You can't swap on a VTEC head for the DOHC ZC because the are no DOHC VTEC D seires heads made, and a B series wont work.
What are your plans with the car? What kind of power are you looking for? Boost or N/A? Street car or track car?
Answer these and we'll be able to help you out even more.
*edit*
Forgot to add, with either of these ZC motors, you can use the stock mounts, however if you get a VTEC one, you'll need a new ECU and wiring. http://www.rywire.com has good **** for that.

Re: 1990 CRX. Yay. (deviate_si)
Well I'm a 17 year old student, so money tends to be an issue.. ($250-$300 dollar paychecks just don't cut it sometimes when it comes to cars, especially with phones and insurance and such. 
) Anyway, For now I just plan on going N/A, but would eventually like to turbo. It'll just be a street car, with a bit of spirited driving on Saturday nights when racers meet up out here.
Does VTEC honestly make that big of a difference? What are the advantages and disadvantages?
Thanks

Re: 1990 CRX. Yay. (xfletcherxx)
Well since your on a budget......you should prolly stick with a sohc swap. they are cheap and easy to fix up without very many modifications. Yes, vtec DOES make a big difference.......i hated not having it....but I'm not sure how good a sohc vtec bones out, but i'm sure its better than a non vtec sohc.
O yeah forgot to post this earlier:
H22=Vtec
H23=non Vtec
F series motors are different in alot of aspects.....some single cam, others dual.
But its better not to think about these......

Re: 1990 CRX. Yay. (xfletcherxx)
well man in respons do does vtec really make that much of a difference.
I was runnin a SOHC mini me (d16a6 block with a d16z6 head) and in a SOHC vtec isn't really a swift kick in the pants like on a b18c. On a Sohc the vtec only engages on the intake portion switchin from a mild cam spec to a more aggressive one and what it does it let you rev more and make more power at a higher rpm as oppesed the the stock d16a6 head.
My mini me pulled a lot harder than the stock si motor. Now I am runnin my rebuilt d16z6 with a couple of parts and a zex 59300 cam and zex valvesprings and since the motor is still new I haven't got on it yet until the rings seat but I am hopin with the new cam that vtec will be a nice surge of power.
Judgin by your questions I think you should stick something simple and cheap since if your doing this yourself is probably your first honda swap. I would go with DOHC zc because it bolts right in and you can stay obd 0 with very little wiring and I think this can probably be done cheaper than a SOHC swap because with a SOHC swap I highly recomend converting to OBD1 (you would need conversion harness, 4 wire o2, obd 1 dizzy) because most people just think vtec is just on or of and that it can be controlled by some retarded rpm switch. wrong when vtec is engaged it requires the proper fuel to air mixture otherwise you don't get the benefit of what vtec actually is.
I think you are a little confused on DOHC vs SOHC stuff.....b series swap costs a lot more and I think with what you want to do a DOHC zc or a d16 swap with bolt ons would be good for ya. I am assummin your is an HF/DX since you want to swap in a D16 so if it is a DX remember to convert it to MPFI otherwise any swap would be pointless.....I hope what I have said helps you and remember that it is just my opinion....PM me if you need any help

See now u have some insight on how much a sohc vtec bones out
but its true what he said......stick with sohc cam if u dont have alot to spend, and if you REALLY tight with money.....dont even worry about the sohc vtec. What kind of Crx do u have? HF,DX,or Si? more info is needed to determine what u should do

actually you can get vtec from a single cam..
the d16z6 or the d16y8
the y8 has a tad bit more power but mostly the same
the d16z6 is a good platform to start out with..a lot of people now a days are stayin single cam.
you could also rebuilt your motor and slap a d16 head on it and create the mini me swap.
mini me swap with the crx si tranny is a good combo and gives you the extra pull for daily driving..with a tight budget
good luck with your plans...SAVE THE SOHC!!

Re: (crx2nr822)
yeah I got some pretty wicked plans for my SOHC.....I know they aren't the bling and power of th eB-series but for us broke *** college kids they are a good fun budget build....
this is what I got so far
rebuilt z6 with about 24.2 miles on it
slightly ported head port match to a y8 intake mani.. port match to a b18 TB
AEM fuel rail
race eng block guard
arp head studs
zex 59300 cam
zex valve springs
DSM 450's
uberdata ready ECU with dataloggin (p28)
plan on turbo probably 7 psi of boost from a super 60.......gonna do a DIY turbo kit was gonna go junkyard but got sick of workin with junk so I sold everything and started over....

Re: (crx2nr822)
well I got the motor with the mani and aem fuel rail for 100 bucks....it had a spun bearing
block guard was 99
cam was 220
valve springs were 160
injectors 50
ECU was 100
getin the crank turned..new bearings and rings and gettin the rods resized was 250
arp head studs 90
B18 Tb 15
I guess it adds up....but I think it will be a good motor in the long run

I bought a complete SOHC ZC for 100$ haha. Had mounts, shift linkage with short throw. dizzy, ecu and a bunch of other crap. Si tranny with starter, no alternator tho. But it was such a good deal!
Single Cams are the **** when your a student haha!

Re: (ludesrv)
Well I just learned a lot about these motors from this post. Thanks for all of the help guys.
The CRX is an HF with an SI transmission in it.
I'll post some pics tomorrow when I get it.

Re: (xfletcherxx)
well you got the si tranny that is a good start.....now when you get a new motor use the intake manifold that comes with it because the HF intake mani has REALLY RIDICULOUSLY small runners and whatever motor you get will have a better one....and best would be to get a y8 one with a b series throttle body.....
