hey guys, im 17 and im just getting into the whole tunner thing. i bought a crx off one of my buddies and hes got a d16z6 sohc vtec motor under the hood still all stock. a couple of people i have talked to have said its worth building up if you change some things ( valve train, pistions ect.) just wondering if it wortht he cash or to just get a swap to a b series? and if so what kinda power it would be pulling at the wheels? thankz

 

With what it would cost to build an awesome D series, you can easily afford a B series and have some significant measure of added reliability. Power output probably won't be that much different either.

 

hell no its not worth it
i have a 200whp lsvtec and i'll be the first person to tell you that its slow as ****.
it will be almost impossible for a d seris to get 200whp on pump gas
its just going to be slow

 

If you want to break 200 hp, then a SOHC setup isnt for you. Unless you're willing to cash out the big bucks.

Only build the SOHC if you have to slowly build the motor (ie: one part at a time), and are not trying to get an assload of HP. But you can also check out carb setups if you are committed to building the z6.

I'm slowly building my SOHC, because I'm in college and I'm not trying to bust everyones *** down the street in a race. My motor is enjoyable up and down the mountainside.

 

get yourself a GSR and call it a day, or go wild and get the K series and call it a year!

 

alright, let me break it down for you. How much cash you got? how fast you really want to go? is this for a drag car/ auto x/ road race? answering these questions might help everyone help you.

but if it's just a street car and you don't really have that much cash to spend i'd go turbo ( yes i know this is the all motor forum) my homie chi, did a home made turbo w/ the t25 even though it's a small turbo, from light to light on the streets it's a fast car. now w/ that being said if you got like 3 g's + people will say gsr, which is a great base, but you might not be satisfied w/ stock power and you'll just want to keep on adding the basic i/h/e. until you realize damn, i should have just bought a 85mm block and work on from there, so in the end how fast do you really want to go, is the real question and how much cash are you willing to fork out.

 

Buy an LS and boost it

 

bring a lot of money at least 6K, then break 230 chp with those D16Z just like ---> https://honda-tech.com/zerothread?id=1313920

 

well my budget is pushing 5 + fho the engine ryte now and im looking at it just as a street car point of view.. i dont want any relibility problems, im just looking to build it up as a strong street rex. also im looking to build this as being a little different. everyone has b serise blocks and i wanted to see what a d block could pull. ive seen some pretty strong ones and wanted to see if i could get something close.

 

crazy track time man... .. nice spec's two

 

new clutch, plugs, zex wet kit, bottle warmer, slicks , good driver = mid 13's

 

gut the crx
some sort of drag radials on lite wieght rims (hx rims are nice)
a mild cam, p&P head, intake mani, header, tuning
and call it a day for a cheap all motor setup

 

boost the d...or even cheaper...nos it till it dies while you build another motor

 

**** you could build a stock b20 vtec and still be quick. save ur money dont build the d

 

you could always go N/A...diy Pnp some bolt ons a ported y8 mani ....and some pg7 pistons should make decent figures

 

its not worth the effort on a d motor. but it can be done! i just have H/E with ITB and a 50 shot, it hauls for what it is while my k24 is in the garage being put together slowly... on the track i run low 14's

 

D motors respond really well to forced induction. You can build one for boost pretty cheap (search 'vitara') and it will get you more power for less money than an aggressive NA build. And the best part is, if you tune it right, you will keep your stock highway milage when you are just cruising along, off boost.

Best of luck with your project.

 

D series parts are cheap and widely available. They are good everyday motors. If you want all out power go turbo. Mild upgrades (cold air intake, headers, etc.) will give you only a slight boost in performance. Adding a turbo to it will be costly and can hurt your reliability. An all motor build will keep your costs lower than a turbo build if you use the right parts. OEM pistons to up your compression and a better cam along with the basic upgrades will give you a quick, not fast but reliable daily driver. Just my 2 cents.

 

The reality is that a D motor isn't going to gain a whole lot of power with just basic bolt-ons.

Adding a small turbo can cost less than an aggressive NA build. I see used D series turbo kits in good shape all the time for $1500 or so. It is also more reliable than a very aggressive NA motor (something with comparable whp to a small turbo), if properly built and tuned. And, it will give you better milage and more torque.

If you are comparing a mild (just bolt-ons) build to a turbo then yes, it is cheaper. And much slower.

To the OP - as mentioned by others, what is 'best' for you really comes down to your power goals and your budget.

 

At 17 I'm going to assume this is your only car. So your Daily Driver. Some of these suggestions are not one day jobs. Keep that in mind.
Not sure where the 200whp came from but a CRX doesn't need 200whp to be fast. It's a few hundred pounds lighter than our Integras.

Not sure how a D series is less reliable than a B. Simpler design, less parts, if properly built it will be more reliable than a B, cheaper parts too.

Since you are in the ALL MOTOR forum, I'm guessing you would like to stay NA.
Here is my very simple set-up on my Del Sol Si a D16Z. Greddy header, Test Pipe, Stock exhaust, K&N filter in the Stock Air box, tuned on S300 121whp/102tq. Stock head, stock block. Could I get more out of it definitely. It's just my DD with over 250,000 miles.


Take a look on this site if you really want to stay with the D series.

i don't think this guy is 17 anymore.. because you've replied to a five year old dead thread...

 

Dang trial users bringing stuff up 5 years old for no reason. Then again maybe I should have read that as well.

 

Perfect for Easter!

 

I was about to reply to this thread with input til I saw this post.

 

Some say yes, some say no. I was working on a 88 CRX slowly for the past couple of years before being transferred to Florida. Unfortunately, the project has come to a standstill and it doesn't look like I am going to get anything done in the near future.

Have a D-series motor. I had the block sleeved out in California. It can get up to 60 boost. Also have top of the line and custom rods, etc. These are
just a few of the things that I have.

My intention was to race the car. So, this little thing has all the things needed for some get up and go.

If you decide to go with the D-series let me know. I am in the process of trying to sell the parts or the whole car - haven't decided.
