Ok first of let me explain my situation.

-college student with low income
-88 CRX DX - daily driver


Ok guys I decided that I was going to swap in a dohc ZC. THen boost with a greddy T25 that I can get for cheap off my buddie.

THEN

I saw this guys 1st gen CRX si with a boosted b16a, and he told me that it would be a wise investment.

ok first off, I can probably have the DOHC ZC in my car boosted for 800-1000. Now Im expecting it to run low 14s non built boosting 6lbs? correct me if im wrong. This would take me about 2-3 months to save.

I can do the b16a for around 1500-1700. waiting about 6 months of saving And also run 14s? and have a better platform to build off of, exp when I save to go turbo.


so if you were me with a low income what would you do?

 

bump you guys must be tired of these posts

 

zc turbo would b easier to fit wit turbo den a b16 turbo but a b16 turbo would make more power and more parts on the b16 becAUSE there is alot of companies making parts for them so my vote goes to the b16 turbo i can relate to that one

 

zc is cheaper to install & cheaper to replace, and supposedly does very well on boost.

 

the ZC is going to be such an improvment over what you have, go with that at 6lbs.

its going to be tough to not turn up the boost for you id imagine...

it also might be a good diea to check in the forced induction forums (search) to see some dynos of the two engines and what youll be looking at with each motor.

then theres also vtec, one has it, the other doesnt. this matters when boosting.

do some more research if you want, but it would be cheaper and still rather fast with the ZC. it all depends what you want the car to do. if you want to go around chasing evo's and sti's then you need a lot of money. but if youd just like to be faster for yourself, then its all up to you.

good luck deciding.

 

mmmm evos and sti's hehe that would be fun, but yes your right.

anymore opinions?

 

I'd say go with the B16 and turbocharge that. The compression is a bit higher on the B16, but not high enough where it will hurt you if you have the proper supporting mods.
B16 will have a high power curve..meaning, it probably wont be as responsive as the dohc ZC. You will get power on top end. B16 is pretty much torqueless. haha
I own one that is turbocharged. So I'm speaking on my behalf. Though mine is just stock setup with a turbo setup.

I would do the DOHC ZC , thats what i have. But remember anything over 200hp u will need to change the pistons and maby some other things. The pistons can only take 200hp. Also u can get the ZC's for cheap on ebay. http://www.ebay.com and just type in ZC and search they run from $400-$600+ shipping.

 

A good drive can get a mid-high 14's and low 15's on the 1/4 mile with the ZC swap in a CRX with the Teg ECU. The b16's just dont have the torque out of the hole like the ZC's do, and the vtec doesnt really come in effect like you would like it in the 1/4 mile. I DEF say Turbo ZC!

thats why you launch the car in Vtec

The ZC will definitely be cheaper to swap in, but dohc ZC and sir1 b16a long blocks are actually very close in price. Maybe a $50 difference.
So replacement cost, shouldnt really be a factor.

 

If you're thinking about building it sooner or later....go B16!

Go for the happy middle ground B18A1 especially if you plan to boost it. There's **** for ZC parts out there...

 

id lookj around for a z6 or a6 and turbo that. easy to come by and can def handle the boost. or go with the zc. either way im say d series.

 

I'm still not sure why the DOHC ZC supposedly "does very well with boost". It's a d-series motor...

Because it's just about the only thing you can do to the thing. Try finding a complete valvetrain for one (cams/valvesprings/retainers).

 

Try buy-EFI.com, JG, crower, webcams. There are several places that sell valvetrain components for the DOHC ZC. This notion that you can't do anything with a ZC is wrong and lazy.

 

B series with nitrous owns.

 

When the hell did that happen? Me = owned.

 

Well the guy is on a budget, Nitrous is your friend when your on a budget and you want to go fast. Just be safe with it.

 

broken piston ring lands dont fit into most peoples budgets. stay off the spray with stock cast pistons. just because the motor is still running doesnt mean the ring lands havent taken their abuse.

ZC has a very cavernous combustion chamber, the poorest of hondas standardization (there are a lot of varieties of them) and relatively little aftermarket support. go d16a6 or b18a1 if you are on a budget. keep the revs under 7500 if you want the b18's ball mount rocker valvetrain to last.

Blah Blah Blah Nitrous will hurt the motor but boost wont? Dont hate because you probably improperly used nitrous.

 

dont get a zc. i wen tthrough two of them and now i havea b16 and it is gr8 except a small problem. btu i mean i have heard that zc's cylender walls are thin. also i have thrown a rod in one. so i mean if u want to turbo it dont get zc. get a b16 and plus u do have more parts available for b16. LATER and good luck

Definitely go B16A if you wish to boost. Yes, a ZC might be cheap to buy and easier to install. But you get what you pay for. Specifically, you get a motor that is internally very weak. You also get a motor with an atrocious rod ratio that leads to MAJOR cylinder side-loading under boost (NOT a good thing). If you get a ZC today and boost it, that motor could very well never see 2005. Because boosted D-series motors with stock internals are hand grenades in disguise. B-series motors are of a much more heavy duty construction, as are associated drivetrain parts such as clutches, transmissions, and axles. Simply put, a B-series motor is much more likely to take a licking and keep on ticking.

As for aftermarket support, is there even such a thing as a new set of cams for the ZC?

And as for the whole B16A vs ZC torque thing, this is more hype than reality. Sure, the B16A does not have much torque. But that's because it is a mere 1.6 liter. And you know what? So is the ZC.

 

"As for aftermarket support, is there even such a thing as a new set of cams for the ZC?"

Yes, Crespo.
