Dollar for dollar is it cheaper to make power out of a D16z6 or D16Y8 (or any D series engine for that matter) with the intended power goals of approx. 130 tq and 160 hp (N/A of course)? Suggestions for making this power? Obviously, intake/head port/cams/exhaust/etc. etc. come to mind but I'm just wondering what upgrades make the most sense. I suppose this is a SOHC vs. DOHC question. I realize the DOHC has more potential but per my power goals which is cheaper? Sorry, I realize this is a noob question and I continue to read as much as I can when I have time just wanted the experts to weigh in on my question. Thanks...

 

If you want n/a horsepower you should bet a b-series/h-series/k-series.

Making that power on a sohc will suck.

 

so the D series should be left for FI?

 

a turbo

 

lol!

 

unless you want to dump $1,500 into building the motor and you won't even make as much as (or close) $1,500 for a turbo setup.

 

wow... i think i'm starting to get the picture... maybe a b series swap is a better idea

 

fo sho...

 

i'm doing that right now and this site has NO help for you. i know i have asked twice. what you will find is that most of them sissy out and go B16 or Turbo.

Your best bet is Port and polish, stage 2 cam and Valve train , skunk 2 intake Man. port matched to the head and a integra 60MM throttle body, Y8 Metal Head Gasket (cheaper then Z6 Metal), D16A1 pistons from a 88-89 integra (give you 12.0:1 Comp), shot peened Stock connecting rods (shot peening lets them hold up to 230 HP), new rod studs and head bolts, 4-2-1 Header, high flow cat, 2.5" cat back and a cold air intake with a K&N filter (Not a Short Ram)

thanks solster... I'll definately give it a read over... about how much are your mods gonna run you and what kinda power will they make?

 

Kinda sounds like a waste of money. For the money spent with those parts plus some more, you can make way more HP/TQ for a lot less work. Plus there's always room for making greater number by building the motor later
\

I'm not trying to dash your hopes or anything for NA power from a SOHC, but i was with my friend and he went against a crx with a fully built NA d16y8 swapped and he was crushed by my friend's car, stock JDM h22 motor+tranny in 91 accord (both have manual transmissions).

 

this is biult

yeah first its a 2.2 not a 1.6 and try driving that on the street.. you wont get far with that spool to say the least.... the reason all hte "sissys" go with the B16 or turbo is cause it works.... its proven to work time and time again... theres no sense in building a D16 when you can build a B16 or B18 and have alot more .... but its your build so good luck with what ever you do

^^agree

Why waste your money on a slow *** D series?

 

a dollar for a dollar mod..to make a d series to 160 HP..u are looking for not just a few dollars ..and turbo it, is the only way to get power out of d series engine and most people opinion about d series... dont waste money on it..save up and buy a b series swap..take it from me..cause i had wasted money on d series and i blame myself of being stupid of buying all the parts for my old d16z6 engines..

 

the b seies swap is the best way to go price to power the k series setup costs 4000 or more the d series cost a lot to make the same power as a b series and a b series turbo making 250 hp will cost about 3500 with fuel management

 

no... youll spend 3500 in fuel managment if your ******* retarted.. all you need for fuel an a 250whp is injectors, fpr and a fuel pump... and a tune but im not considering that part of the fuel system sense you gotta do that regardless... you can drop 3500 in the the fule system if your going for 600+whp as in getting your tank sumped for an A1000 fule pump, -6lines, injectors, rail ect.... yeah your gonna spend alot, but for 250whp.... a grand at most and thats highballin the sky

 

These people are clueless.

The D16Z6 is slightly better. But dollar for dollar, you start with the motor you have, or the same obd series as the car you have. Z6 is OBD1, so if you have a 92-95, you want a Z6. Y8 is OBD2, which is 96-00. If you haven't got the car yet, then go with a 92-95 and get yourself a fresh JDM motor/tranny for around $600.

You don't want to port or polish the head. What you want to do is get some "Vitaras", which are aftermarket pistons originally designed for the Suzuki. People have been making serious budget power with these. Then you're going to want a cam. And obviously everything that goes along with pistons and a cam. Get an ebay intake pipe that is about 62mm diameter and as long as will fit in your engine bay. Get a free-flowing custom exhaust with a Magnaflow muffler and an ID of about 2.25 inches or slightly bigger.

Another approach would be to simply get in line for an Endyn Supercharger kit ($3500). Pricey, and yet it's the same cost as putting in a B16A. You could get a B18C for $3500, but then you wont have any money left for all the little things you're going to need to go along with it. You'll only be making 180ish at the crank, while the D with the supercharger is going to making 200ish at the wheels.

Dollar for dollar, the money you spend on your D is going to make more power than the people that spent the same amount on a B.

Go over to d-series.org. All the closed-minded, unimaginative people on HT are just going to say "swap it for a B, no an H, no a K". Those are all great motors, but for reasonable power goals on a BUDGET, they're all dead ends.

 

Yes, it can be done, it's not cheap.

For about as much money as a GSR swap, you can make your D16 faster than a GSR.

You need a heavy duty header (no DC Sports bullshit) like the bisimoto header, HIGH CR (like 12:1), ITB's would help as well, but any better flowing intake manifold will do, a pretty aggressive camshaft (but not one such where you'd have overlap), a high flow cat to a 2.5" exhaust all the way back - muffler inlet/outlets both 2.5"+. Use a CAI. Maybe after that stuff you can mill the head down a bit (not too much) and replace the head gasket (since you'll be dealing with a much higher compression ratio), then port & polish the head.

Also, if gas mileage isn't that much of a worry to you, use custom gear ratios to make your trans shorter - it'll make you faster, but won't increase HP.

That and a few more trimmings will put your HP rating up there.

Bisimoto's street CRX had a full sound system and still beat GSR's.

Put all of that crap together on a Dyno - and you should have a nice all motor D. Though, like I said before, it'll cost you as much as a GSR swap will, maybe a little more if you do a lot of the machine work I mentioned.

EDIT:
PS: I'd say go with the Z6 over the Y8 - it seems to flow better for making optimal HP.

I still think it's F#cking stupid to build an "all motor D" as a street car. If you want a budet build, do a D series turbo. I'm not saying that it's impossible to get power out of a N/A D series, but come on, I don't think the OP is trying to reinvent the wheel - they just want a nice car/ engine combo that will be quick and reliable.

Yeah its built, please dont tell me you think you will get anywhere near bisi's build. His motor and car cost more than most people on Honda-tech make in a year.

 

true d series are far more better the b-h-k series the motor are throwing the wieght ratio off too much i know cause i use to have a b18b swap in my ej8..my buddy has a d16y8 and used d17 internals and by tuning it right he got 174 hp and 137 tq..ahhahaha and it only cost him 1700... because my bro is a machanic..and trust me it is fast...
