I've come to the conclusion that it will be one of these or the other.
I have a spare Y7 block and Y8 head laying around.
I want to keep it N/A and add a little kick to the engine.

Should I stroke the motor out with a D17 or keep my P2E pistons, or say F it and drop in the PM6's ?

The compression ratings between the 3 would be
D17Y8 - 9.93
P2E - 9.96
PM6 - 10.34

What would my torque and horsepower be like compared to stroker? I have a feeling that the torque will be higher from the stroker, but will the hp be higher too? By how much?

Is spending several hundred more dollars justifiable to stroke it ? Would the gains be worth it? Or save that money and spend it elsewhere.

Long term my goal is only a fpr, tune, port & polish, I/H/E, Delta 272 or 260 cam, adj cam gear, Y8 springs, mill job.

Thank You.

 

Oh, you funny guy, you.
Building an N/A motor is NEVER justifiable "cost/benefit" wise, but this applies exponentially to the little D series.

I'm not knocking the D series, I would love to do a D series build myself someday, but you gotta understand that you'll be spending your money on hardly any power.

That said, stroking it while getting an even higher compression ratio is probably your best bet, but then you'll be looking at getting even more supporting mods, such as:

Camshaft to take advantage of the increase in compression, along with adjustable cam gear

A good header, because you won't make any good power out of any of those mods on your stock header

And better induction, think ITB's or Skunk2 manifold, on the cheap side along with throttle body

After all this, you will still need to get it tuned.

Why did I go through all that list? Because you can't just simply change your bottom end without changing the rest of your setup to support it, and expect to find any noticable boost in power. Now, you have your research cut out for you

 

I wrote down what I am planning to do to the engine. It's I've researched long and hard. That's my most feasible option. Want me to spell it out for you?

D16Y block bore honed and decked
Y8 Head milled, PnP, Y8 intake springs, Delta 260 or 272 cam with adj y8 cam gear
4-2-1 Ebay or DC header
2.5 SRI
2.25 or 2.5 catback exhaust with hi flow cat/test pipe
Y8 head gasket, full rebuild seal kit
Y8 Intake mani

I think your forgetting or you don't know that D16 parts are cheaper than any B series.

 

So... thousands of dollars and time all to run an inferior motor that will make less power than a B16 with boltons?

I think you're a noob.

 

I'm not trying to race B16's, B18's, or even B20's.
If i was, I would go turbo and smoke their ***, but I'm not.
I'm trying to get more kick out of what I got.
D series parts are cheap.
It's not about racing at all.
Its all about daily driving, having fun working on my car, and grins.
Swapping to a b16 or any other B series is pointless to me.
I'll run with what I got. Not trying to break necks or track records.

And it ain't gonna cost thousands of dollars. Delta regrinds are 80 bucks!

 

Alright alright, I wasn't trying to sound smartalec, it just sounded like you don't quite realize all the aspects of building a D series. I respect your build plan.

That said, the most fun you'll have on the streets is more torque. This is evidenced by swapping a B series for the H series (all I'm saying is the H has more torque out of the box and that you can definitely feel it, that is all).

So in the simplest form, my vote goes to the stroker for sure.
However, since you're looking to upgrade your header and cams anyway, you might as well go for higher compression pistons as well. I don't mean Arias or anything, just mayber some higher comp OEM ones that will work with your setup. I know on the H series you can mix and match the 2.3 crank with certain OEM pistons and get killer compression, I'm sure the same applies here. That may cost a couple hundred dollars more or whatever, but I think it would definitely be worth it for your build.

BTW, where exactly are you stuck in texas, if I may ask

 

Lol, its all good, I just hate it when people always scream out swap! or boost it! Of course the gains aren't going to be all crazy and stuff, I know that!


With the stroker all I would need is a D17 crank, pistons, rods, rod bearings and piston rings. Not expensive at all. Comp is 9.9, same as the Y7 with a Y8 head. the Pm6's from a D16A6 would give me 10.3. I think it would just be cheaper to mill the head tho, but i would have new pistons hmmm.

Anyways I'm in San Antono, not far from you I don't think.

 

Oh nice, you're pretty much local then! I can honestly count on one hand how many honda heads I know in this area, I know theres probably quite a bit though.

10.3 is getting there...with milling and a thinner head gasket it'd bump compression up to a good number, I think. But that's just me, 10.3 is probably really good for this set up

 

I'm pretty new here, and don't know anybody that's into Hondas lol.
I see some, but not as many as I did back in L.A.
I think I'ld go to 11.1, or slightly below

 

Yeah this is the south, mostly trucks and muscle cars with your occasional maserati running around S.A. lol. We're kinda fish out of water here, I think, but I kind of like it that way. Just something cool about outrunning v8's with a little high revving motor

11 would be sick, used to you'd have to run premium gas for that, but with tuning these days I don't think you'll have to
