SOHC Potential and Power
 

Hey,

I've searched and haven't found any solid information or links related to SOHC's potential and power. I'm interested in seeing what setups people have used on their SOHC engines, d16z6 in particular. I realise no power will be gained from an N/A setup, so basically building the motor internally, with FI and some bolt ons is the way to go for this engine.

Reason I am curious is because I am looking into swapping, but the idea of a turbo is someting I've began to look into. The swap I was looking at is either b16a or b18c1. Both high revving, high compression engines, and good for n/a setups which is what I am leaning towards, for reliability and daily driving.

Now I am exploring other options of sticking with my current engine that has low milage, and boosting it.

Thanks in advance.

Boost it, blow it up, swap it, boost it, blow it up.
That is my typical phases with motors.

But seriously you want the car to drive everyday? i would say keep the single cam in for right now and build it you can pick up D series rods and pistions for pretty cheap and then slap a T3/T4 on there and boost the hell out of it and when driving around town just turn the boost down to like 6psi or so and you will be fine. Also how much money are you willing to spend? if it is a little more than the turbo swap it and spray it then boost it a little while latter just my .02.

Also i think that SOHCscreamer i think that is his name has a extremly nasty all motor single cam so search for him it think that is his name on here. all motor or turbo both get respect from me.

I was thinking that with either the b16a or b18c1, I could boost it down the road. I'm not sure of the prices on t3/t4, but I can currently afford the b16a, if that's helps at all with my budget.

Thanks for the input too!

If you want to boost your D16Z6, let me know. I'm a lil' south of you, with a brand new GReddy kit for your application.

Spade and Mista Bone are the best for D series around here.

My Z6 is in a 93 CX. Basic bolt-ons (i/h/e), AEM fuel rail/FPR/pulley kit, Taylor ignition wires, ACT clutch. Ran a 15.8 at S.I.R. two summers ago. Full interior too. I now have nothing but two seats and a dash for interior, and a CF wing. I didn't go to Pacific Raceways this summer thought to see if any time could be dropped....even though I'd only be like 0.1 of a second.

Re: SOHC Potential and Power (DMoney)
 

you can make your d series a very fast motor if you want to. contact dh-racing.com and tell them their vegas hook up recommended you. they're building my setup. they can do anything. and for all you people who are gonna call me a newbie go FUCK YOURSELF. https://honda-tech.com/forums/images/smilies/emwink.gif

oh yeah.. they have a 200 whp SINGLE CAM ALL MOTOR in their CRX. thank you very much.

Thanks for the fast responses guys. Any other opinions from others?

Wow...I can't imagine how much money they must have had to put in that engine to get those kind of numbers.

The key to the SOHC is to get into the motor. I will be starting my build on a SOHC nonvtec shortly. I am looking for 160 whp. That is a realistic rating. I am wanting more, like 170-180. That is all motor.

Talk with Mista Bone about it also.

I have seen D series motors over 150 with I/H/Hondata. Had PnP and a lot of tuning. That was a Y8.

Over 150 what?

whp i'd imagine.


Andmy input: Built SOHC turbo is a great platform! I'm going to be setting up mine in the spring for 300whp reliably, should be about 7 grand.

I don't mean to sound like an ass, but my old stock 1992 Si with the only mods being an AEM CAI and a Centerforce clutch ran 15.6 back in 1998 here in GA. The car was 100% stock otherwise including stock height, 14'' steelies on Michelin MXV4 all season tires, and the only weight reduction i did was pull the spare out.

I ran 15.7 all day long, but I did hit 15.6 twice.

What elevation were you running at?

check my sig, there is a link with good info on d-series. Also check http://www.d-series.org and http://www.alternativehonda.com

Re: SOHC Potential and Power (DMoney)
 

don't waste your money on a b16 if you already have a z6. If you must swap get the b18c1. The d series have great potential as far as forced induction and they also have good potential all motor too. I have seen some d series with over 160whp n/a.

Re: SOHC Potential and Power (SOHC_MShue)
 

I see all this talk about "I've seen D series over 150whp, 160whp, 200whp all-motor" well shit post up some graphs and specs then!

I'm not saying it can't be done, but the proof isn't in "I saw" but more in pics themselves.

Oh and one more thing:

<FONT SIZE="7">THIS WILL NOT BE A SOHC VS. DOHC TOPIC OR ELSE IT'S ON LOCKDOWN!!!</FONT>

So post those dynos and specs.

you want a fast SOHC....

http://www.hondaraceengines.com

they can do N/A or FI.

FI is going to be the best place to make power. SOHC can't get head flow without a lot of work in N/A form. The ports are small, the valves are small.

They make good tq and hp when boosted though.

And no matter what anyone tells you....go one step bigger on the exhuast housing if goin boosted. That's where most ppl come into problems holding headgaskets or making low power.

Re: SOHC Potential and Power (B18C5-EH2)
 

all motor sohc's arent a bad choice..with my setup i was running low 15's on street tires in a heavy azz 97 EX coupe w/ no weight reductions..sorry no dyno charts https://honda-tech.com/forums/images...s/emsmilep.gif

AEM CAI
DC 4-2-1 header
axle back exhaust
reprogrammed ECU (was gonna run a cam and VS but ran outa $$)
port/polished head
bored out throttle body
port matched intake manifold
ACT clutch
lightned flywheel

Re: SOHC Potential and Power (DMoney)
 

Let me just tell you this....when turbo and high compression mix, so does your parts supplier and the bottom of your pocket. I originally had a b16a2 with a greddy 18g on it and it was simply high maintenance. Unless you have the time and money to build your motor from the bottom end you will only ever be able to run low boost safely. I pushed my b16 on stock internals running about 8 psi and even then i had to fether the gas or it would spike up on me. If you are going to buy another b series motor i would recommend building that motor and seeing how you like it first. Then if you arent satisfied with that motor, because you already have your motor built, go ahead and start researching for a turbo set up. Good luck with your project. Oh....i just bought a jdm type r motor for my civic, and beleive me if you have the money for this swap GET ONE. I love it so much more than i did having my turbo kit. Its no where near as fast but so much more fun to drive. https://honda-tech.com/forums/images.../h-emblem4.gif

Thats fucking impressive tom https://honda-tech.com/forums/images/smilies/emthup.gif

And everyone...if you wanna do N/A d-series, Bisimoto, MistaBone, Spade and InfinateNexus are your guys. InfinateNexus ran a 14.2 on street tires with his all motor Y7 in a 96 coupe...impressive shit https://honda-tech.com/forums/images/smilies/emthup.gif https://honda-tech.com/forums/images/smilies/emthup.gif

Really? I guess it is seeing as how I see a lot of Z6 swaps into CX/DX/VX hatches running mid 15's too.

:shrugs:

I did not ever lose to any 99 Si coupes even when they had bolt-ons back in my stupid street racing days. They usually ran 15.9-16.2 at our local strips. Then again they also weighed 2600lbs. to my 2269lbs.

125 shot on a Y8 will get you 14.4's all day...got slips to prove it too...

Re: SOHC Potential and Power (B18C5-EH2)
 

CX/VX: 2094 lbs
Si: 2326 lbs

Thats why I said it was impressive...most people who run Z6's in lighter hatchbacks have a bit more done than a CAI and clutch

Miss-shifting going into 2nd every time. 2nd was pretty much gone, so I lost time waiting for 2nd to catch without grinding it forever. That tranny siezed later in the week. https://honda-tech.com/forums/images/smilies/emsad.gif

Re: (Mildly Interesting)
 

125 shot will do what??????

First time out with ZEX 55 shot I went 13.97 @ 97 mph.......

Now that I've learned more, 55 shot gets me 13.800 @ 98 mph....

Re: (zseeanz)
 

man ive had D series and B series.

D series for Boost and reliable
B series for NA somewhat relable but expspensive

I just sold my crx with a B16A init it was fast and so forth

I know have a 99 Acura 1.6 EL which is a civic with a D16Y8 and im running 10psi i made 215hp and 170ft lbs with a stock exhaust with no probs.

Change the rods and pistons ur good for over 300whp and for any of you guys who have been in a 300whp car its all over the roads 350 is over powering the roads and just spins only good for the track.

Thats my .02 cents im going to build my d series

Put it this way u can have a fully built D series for same price as just buying a B series motor. and the Turbo D will be faster. https://honda-tech.com/forums/images...es/emsmile.gif
