How to squeeze power out of a SOHC?
Year 1996 D16Y7. So far I have a CAI and axle-back exhaust. I plan on getting an EX header, hi-flo cat, and cat-back exhaust retrofitted. What else can I do to squeeze some juice out of this motor? No NOS planned or FI.
I need usable power and torque. Oh, no swaps either.
Thanks!!!

you can always do I/H/E a cam gear, and Fuel pressure regulater...and tune it all down with a VAFC...but don't expect anything dramatic....like sub 15, or in some cases 16 second runs.

Re: How to squeeze power out of a SOHC? (bonker)
the only time you will see any power from a SOHC is if its in a 88-91civic or crx.... my crx with the d16a6 pulled 15.4 with i/h/e...... if you want all motor powr go b series.....

Re: How to squeeze power out of a SOHC? (bonker)
Yikes!! Well I'm screwed. What is involved in the head swap? What components do I need to accomplish this task?

Re: How to squeeze power out of a SOHC? (bonker)
just go with the p&p.. then bolt up a JRSC... there's a guy on Purehonda.com that has that set-up in the 14's. With a street turbo cam, p&p'd head, and basic bolt ons.. that car should fly.

Minime's suck, it's just a VTEC D16, like a stock one.
The most I've ever seen pulled out of a NA D16 is 150hp. But that takes thousands to get there.

Re: How to squeeze power out of a SOHC? (B18C-EJ1)
First of all....Boost is the easiest and most effieceint way to get power out of the SOHC. My p&p'd head with 5angle valve job and cam came at the $1000 mark. I also upgraded to an EX manifold and ported t/b which came to $240 for both. Once I can get my car on the dyno to tune it... I'll be looking to be in the high 120's or low 130's in hp. That alone puts my in direct competition with the B16, and as for the $2300 difference in price... I'll strap on a GReddy turbo kit at which 5psi on a ported head will perform like 8-10psi on a non-ported head. At that point I'll be in the 190hp-210hp range... and this still leaves me with $700, and a car that has the abilities to get into the high 12's. more than 1.5sec quicker than the swap would have put me in the 1/4mile. And for ***** and giggles... with those extra $700, I would invest in an extra $300 to get a Quaife differential installed. Be a leader... not a follower.

Re: How to squeeze power out of a SOHC? (MrDX)
actually the biggest gain would probably be swapping in an ex trans instead of that long geared dx/lx trans u have. i have a 99 cx, i used to be turbo'd now i am trying to build an n/a d-series i have swapped the trans for the ex and it makes a pretty noticeable difference. u can make power from the d-series if, there are quite a few very low 11 sec. d-series powered all-motor cars bizi ezerio's crx and jay yuson's crx come to mind. in one of past issues of scc they did an article on all motor honda's and one of the motors was bizi's 1.6 sohc they got 215 hp to the wheels from it i think it was r and d racing (not 100% sure on that name can't remember) a while back i did call them and they have stroker kits for the sohc. also if u do a little digging on the net u will see that there are quite a few road race cars with d-series making around 220 hp. even j-g's site lists a road race d-series making over 200 hp. there is gude of course alot of people will talk smack about them but i know quite a few people that have gotten their stuff for the sohc and have had good results. one of my freinds used to have a 90 si hatch w/ the gude package and he was running mid 14's not too bad huh. i think in the end if u decide on a swap or sticking with the d-seires it all comes out costing close to the same depending how far u decide to build the car. oh yeah price i was quoted when i talked to r & d it was like 1695.00 to build it up to a 1.8, he also said that setup made i think 140 hp and 130 tq w/ a stock head and cam so just imagine the possibilities w/ a ported head and wicked cam.

Seems like you are on a low budget. So here....
Intake/Header/Exhaust, Fuel pressure regulator, Pulleys. That will be some things that you can do until you decide to spend money.

So, let's see what your total is now...
$1240 ex manifold, P&P'd head
$250 dyno session (cheap)
$1800 GReddy turbo kit, intercooler, and BOV
$Free Self installed
Wow, that's $3290 <----------------GSR SWAP or B16 SIR2 swap with GOODIES!!!!!!!!
and a car that has the abilities to get into the high 12's. more than 1.5sec quicker than the swap would have put me in the 1/4mile. And for ***** and giggles... with those extra $700, I would invest in an extra $300 to get a Quaife differential installed. Be a leader... not a follower.
Realistically you may be able to get in the 13's "IF" you're a good driver, but 12's are going to cost you even more $$$.
I've come up on many GReddy SOHC Turbo cars, and they're no match for my GSR Hybrid.
Remember, after the Turbo is installed, you'll want to have that dyno tuned, install a 255lph fuel pump, plus you're going to need a more freeflowing exhaust.
To get into the 12's you'll need to strip the interior, beef up the suspension, raise the boost (not too much, they're only stock rods & pistons) Etc... Etc.... Etc.....
You get the idea..........

Re: How to squeeze power out of a SOHC? (B18C-EJ1)
hmmm when i had my greddy turbo on my car i pulled on most of the hybrids i ran, in fact realistically a hybrid may run what low 15's high 14's wow, my freind had a greddy kit on his ex and he ran 13.6 w/ it (truning the boost up). and i know for a fact that he didn't spend more than 3000 on his total setup. a swap will cost at least 3000 and than u still have to get all the other crap either boltons or some form of f/i maybe. so really a b series would cost alot more than building up a d-series. he could just slap the turbo on there and call it a day. when i put my greddy kit together for my sohc i got the basic kit and added what i needed. i got a blow off valve from a 911 turbo it cost like 40 buks, i bought a 190 lph fuel pump for $80, and got a used intercooler from a busted dsm. the i/c piping was done by a friend and myself using exhaust pipe tubing. overall i think i spent an xtra 200 buks on top of the cost of the kit. so thats still under 2000 dollars and thats for a car that will be faster than just a swap.

There is no squeezing anything. Not unless you quick squeezing your ***-cheaks together so hard and dump some money into an engine swap. Thats it.

Re: How to squeeze power out of a SOHC? (93LSivic)
Well... all the labor I do myself. Dyno time is free from the place I had my headwork done...and running at 5psi, stock level... an intercooler isn't needed, it's a plus, but not needed. Plus every last B16A2/3...Not A1 is about $3000-$3500, i don't know where you're getting these deals from, which 3500-1240= 2260 around 2300... and yes a new kit goes for about $1600...so 2300-1600=700... give or take, but it all depends who you get your kit through.... numbers don't lie. I've seen some swaps run like champs.. and others like ***. There's a guy in PH posting 135hp and 98ft/lbs on a B16A3 from a 2k Si with bolt-ons. My DX puts 101hp and 95ft/lbs to the wheels now w/o having put the head on...and if you trust putting in a used motor w/o replacing or inspecting gaskets, timing belt, and waterpump...then I foresee problems in the near future. BTW....stock internals can support about 190-220hp max. I never once mentioned labor because it isn't a factor for me, thus my numbers are dead on....unless you're going to punish me for being off $40.

Re: How to squeeze power out of a SOHC? (MrDX)
Here you go
I'm going to describe my old LS engine.
Purchased for $1800 COMPLETE down to the last nut and bolt, Engine had 21,000 miles on it.
Sold my SOHC VTEC engine for $700
P&P'd head - $250
Chipped ECU - $100
Crower Cams, springs and retainers - $FREE (used as a test car)
NOS - $350 (used direct port kit)
Also had AEM intake, DC headers, EVO exhaust, Test pipe among other stuff.
Installed everything myself.
Off the bottle - 155HP 135TQ
On the bottle - 266HP 196TQ
Best time 13.2 on street tires.
So now go look at MrDX's numbers. Add them up and see what you're going to eventually spend.
Just go with a DOHC engine. HELL, forget the VTEC, go get a CRV engine and start from there. You get 146HP and 133TQ. Not a shabby starting point. That engine has more torque stock then you would ever pull out of that 1.6l SOHC.
Remember, HP sells cars, TQ wins races.
OH and MrDX, how many SIR2's you want. I'll sell them to you at $2400/ea, all day long...............

Re: How to squeeze power out of a SOHC? (B18C-EJ1)
If that's the case... then I'll be the first to admit I've been beaten and apologize to B18C-EJ1. Regardless of the fact... he's right and I'll always stand by non-Vtec's due to more torque from the beginning all the way up. This is why I insist in building the D15B7, not only to pioneer more products, but also to get some key respect once it's all done from the BIG HEADED ricers. My definition of rice is a million stickers, aluminum spolier wearing, -3degree camber people with a 5" fart pipe on an automatic car who swear that they are G-D's gift to the world. Just my .02
BTW... free valve train components are not included in all swaps... only those fortunate enough to run into a deal like yourself.

Re: How to squeeze power out of a SOHC? (B18C-EJ1)
and where'd u get a head ported for only 250, i'ld like to send them some of my stuff, all the quotes i have gotten are anywhere from $700 to $1200 to get a head ported. and basically it just comes down to what he wants to do d or b-series who cares its his choice

If you are going to swap you might as well swap a B18, more aftermarket support for the B18 engine then all other engines on the market.

Re: How to squeeze power out of a SOHC? (sohc_boy)
have to correct u on something..
BISI..is using a 1.5 liter currently.
but YES..power can be made from a D series..
and B series weight a lot more than D
