maximum engine displacement

[lilryanadamse]

what is the safest the d16 can be bored out to. stock is 75mm correct? how far can you go on stock sleeves, and how far on aftermarket sleeves. and what would the final displacement be. do they sell stroker cranks for our motors.

[SpoolinSol]

can't you use d17 internals as a stroker kit? I doubt you can make it too 1.8L...

[lilryanadamse]

you can use the crank. i was more interested in the maximum bore size.

yes there is a zc motor that was all the way to a 1.8.

but with aftermarket sleeves u can get 78mm pistons.

with a combo of both d17 internals and 78mm piston it get pretty big!

But is not good to stroke our motora because that make them even less square there for its harder to make good tourge. but gets some good sleeves and bore her out it makes it more square and helps pretty good.

there ya go

You can get 79mm sleeves and pistons from JGE, that makes your engine to 1765cc. That's 10% more displacement, and roughly 10% more power and torque all the way. Has potential for even more, because compression bumps up nicely and bigger bore helps valve shrouding a lot in these engines.
D17 crank (94.4mm stroke) would increase that to 1850cc.

I wouldn't bore stock sleeves bigger than 75.5mm, is you're looking for high power/rpm.

thanks for the info my N/a buddy thats sick shit man thanks!!

2.0L SOHC D motor has been done.......but a 1.5L was faster, go figure.

who built these?

[lilryanadamse]

thanks for the help guys.

[kprcivic91]

^x2.
How they did it?
Maaan 2.0 shoc holly sh...t!!:shocked:
I want that too!!

Didn't read the magazine article?

[gpny]

I remeber seeing a sohc stroker kit on ebay a few years ago. customs flat top pistons, regroud crank, and custom crower rods... they wanted 1500 at the time...
I would be interested in a destroked and higher revving d16, such as endyne's...

[transzex]

Like a D15B crank in a D16 block????

Main bearings are the only thing stopping me.

[Dibble]

What mains do you need?

Why don't you get lopez to regrind you a crankshaft? IIRC they are fairly reasonable cost wise and do great work (Bisi's motors???)

[transzex]

Regrind????

first, I'd be going from 45mm to 55mm mains, either weld up the crank or find spacers for the mains.

Adding .250" before grinding to 5 mains and then grinding, likely to warp the crank.

Although, I have hammered a steel crank to straighten it, not what I wanna do to a I-4 motor.

[gpny]

Regrind a d16 crank, and offset the rod journals. then run diff rods...

[transzex]

thats $750+

Spacers will be cheaper.......

[HONDA300]

so what would it take to run a d17 crank in a d16 block and would the hp gain be worth it?

Is it safe to rev the D17 crank up to 8000RPM with a Crower Stage 2 or 3?

[EsiNA]

Has someone rev the D17 stoker that high (8000rpm)? Or how high has someone rev it and how high has someone rev the D16Z6 engine?

Thanks!

[SOHCinWA]

Somebody from goldeneagle had 81mm pistons in a D series. I know cause one of my good friends works for ARIAS and he designed the pistons for it.

[88cr-rex]

Forget that mess . . .

If I ever do a decent d-series before the motor comes out of the crx for the buick motor, I'll do the biggest d I can make, put my carb manifold on it and hook up the fogger.

Think bore not stroke, Power follows the path of RPM

[burnin_ruberv8]

Yeah, I'm surprised why people wants even a lower R/S ratio and more undersquared engine???
If you people are getting 150whp with the already low R/S ratio'ed D... then a better R/S ratio and a bigger bore would be enough to unshroud the head, have a less undersquared engine(b16's are oversquared ;)), and increase C/R... try to imagine what kind of power would be produced with a D by combining for example with a head from Dh-racing... high numbers would be easilly achivable!!

[BigTuna]

Because they think bigger is better, power is fed by cam, cams need rpm, monster stroke is RPM's enemy. YES i know prostock honda's with B's have stroker cranks but your taking about engines that are torn apart a ton and are ticking time bombs. If you have money to burn and enjoy swapping motor build a big stroke high RPM motor.

FYI there is a huge difference in 92mm and 94mm strokes with a 75-80mm bore with a D and the same stroke on a 86-87mm bore B series.

[SOHCinWA]

This is why i love my D15.... People always tell me to get thd D16. The R/S ratio is closer on the D15. Plus with bigger bore, even closer. More revs, more cam, mmmmm yeah more power.

[BigTuna]

My next D will use a 1.5L crank :-)

[SOHCinWA]

I like the loook in people when they look at the big "D15" stamped on the block anyway. :D

[94EXa2]

what would be the point (if any) to put a 1.5 crank in a 1.6 block instead of just usin a 1.5 block?

[88cr-rex]

man, I am going to have to do that motor now!

We'll see whats up with the d18, carb and the fogger :D

[BigTuna]

Recipe for a bomb, Power Adder+ Huge Stroke+Thin Sleeves+ RPM= KABOOOM

[88cr-rex]

youd better hope so, if I was in maryland I would call you out and find out :D

But it won't be for another couple of years or so . . .

It will definetly be a frankenstein, I got enough SBF and a few SBC parts to hack something up.

[pearl62]

If you can get a D14 crank shipped over from Europe, then build a a 1.6l with a sleeved 78mm bore. With the 84.5mm stroke you get a 1.62 R/S ratio, for great high RPM!

Guys are swapping out their D14 all the time over there... I just haven't found anyone interested in shipping one yet...

By using the D15 crank/D16 block combination you can make use of the added deck height from the D16 block (212mm) vs (207.45mm) of the D15 block... if used with low compression height pistons you can compensate with longer custom rods and achive a high R/S ratio for example... D16 block + 27 mm CH custom pistons + 142.75 mm custom rods + D15 crank = 1.68 R/S ratio with about 2000$ and that's using VERY light wheight N/A internals :bravo: !!!
That's what i plan on building but i'm using the D15 block for personel reasons... and by adding a deck plate i will achive an R/S ratio of exactley 1.7 i just want to see the .7 number lol :TU:

[s_18]

We have lots of D14s here... Many have replaced them with B16s...
Maybe I should get a crank to have around.

I take my D16 to 8k, and that's about how high I would dear to take it.
A 78mm bore in my engine would be the next on my wish list, but it's not going to happen now.

[EsiNA]

Has someone try to put a d15 crank or d14 crank in d16z6 engine? Whats the problems? And if you must replace your oil pump with the d15 or d14, abd whats the case with crank pulley?

Can someone explain that?

[pearl62]

From everything I have seen, the D14 is physically similar to a D16Y7.

[SOHCinWA]

Just got off the phone with my friend that heads the sport compact side of ARIAS Pistons, He has convinced me to send him a D15 block I have laying around and he is going to have 81mm sleeves put in it.. Sounds like a money pit is coming. Oh well, its gonna be fun. :D

[burnin_ruberv8]

I'm going for the same thing... I was thinking about 78 and 79 max if it were safe... (The exospeed limit)... are you sure you can push 81mm out of the D-block and still mantain cooling proprties? did somebody try this before?

[Belette]

Sorry, but when I'll invest more than 2000$ in a rebuilt stroker D block to get poor rods stroke ratio and get maybe 10-15hp and tq, why not go to a F series you'll get the bore and stroke you want for cheaper than K or H.

D is a small engine, why trying to get it big ? Just buy a bigger engine or do something nice with 1.5/1.6liter displacement like going turbo/nitrous/SC or anything else who will help torque instead of increasing displacement.

[SOHCinWA]

Yes it has been done already. My friend at ARIAS said there were no cooling issues with the other 2 motors. It is pricy though. However, all I am paying for are the pistons (at my cost). Getting the sleeveing done for free. Dont want to stroke the crank. I want this little motor to be able to rev quick and high. 81mm pistons with an 84mm stroke, thats almost square and thats what I want.

[burnin_ruberv8]

If your going that route i may be right behind ya man ;)
an 81 mm bore will give the D15 a jump in displacment from 1493 cc to 1741 cc!!! and this isn't just displacment... it's valves unshrouding and more piston area... D's seem to LOVE bigger bores... i say if your going that route... why not attach a deck plate(to increase the R/S ratio)and push this project to the extreme??!! that's what i'm doing...
