stroking a d!

[siba]

hey all,
i have a D16y8 in my vti coupe and im going to eventually turbo it and was wondering if stokin the D16y8 engine to a 1.8 from a 1.6 would produce more power then just the 1.6 turboed?? how much more kw atw would i gain goin from a 1.6 to a 1.8 NA?? other mods to my engine is just the K&N filter with 3' chrome inlet pipe and a 2 1/4" straight through exhaust system.

cheers

1.6L turbo will make more power than 1.8L stroker

stoking will cost a fair bit too

[siba]

how come it wont make more power?
how much will it cost roughly and wats involvd?

[michael_antoi]

hard to find stroker kits for the d-series in australia...i think

try abroad - www.d-series.com

[Weq]

there is only one stroker kit ive seen for the d. around 2k USD will get u a custom crank pistons and rods. stocked out to 1.8~l. not worth it ;)

[michael_antoi]

how much kw would that increase?

[danni_d]

1.6 turbo will go much faster than a 1.8 NA because it the 1.6 is around 96kw i think.. and if you turbo it you could possibly get from 60-80% more of the power on top depending on how well it's been tuned. 1.8 NA will just make it run well for an NA car but then if you want to keep it NA then it will cost you quite a bit to make it fly. but i guess it's all up to you. what do you like? TURBO or NA?

[bennjamin]

there was a MUGEN displacement increase kit for the mighty old ZC many years ago - increase to 1.7l - add cams + Mugen ECU gives you 170hp...wonder how much it cost in the day ?

[danni_d]

whats this MUGEN displacement increase kit for? the d16y8?

[type one]

i think benn is referring to D16A8

[danni_d]

i see i see.. so how much would that cost?

[bennjamin]

It is discontinued. Stop spamming with irrelevant Q's ok.

back on topic -
BTW , IMO stroking a normal d16y8 would not reap much benefits at all ? Possibly the 1.7 crank will fit for more scope but at what cost ? Its no doubt much cheaper and more effective to wack on a turbo :)

[siba]

yer i wanna go tirbo but just i saw on high octane overboost they did this to the crx-recon the engine and made it to a 1.8L and then turboed it and was making 273kwatw on 17psi and was making 170 sumthin at 9psi i think so i thought making my eningine to a 1.8 then turboing it would have a huge power increse?? yes?? no?? please help on this!!

cheers

[michael_antoi]

yeah it sure friggen would...

stroking kit (if u can source one) - $2k probably more

plus price of turbo and upgrading internals..


your in for alot of money...

might as well dump the d-series and go for a b18 or something

[bennjamin]

just turbo your D series engine - there are lots of examples in the US and abroad runnign good numbers - also our local hero Weq has a vti with a nice turbo setup being worn in as we speak :)

[Terry]

if u have money to burn..........get the intake manifold (Not taking about CAI), stage 3 cam shaft, valve spring, priston, polish engine, e-manage or buddy club spec A computer, should be good at 170-180hp @ 8500rpm.....Hear the engine scream.....and beat other car by your NA power! Thats the spirit of VTEC~


I havent see ANY people in Australia done this on the their SOHC VTEC engine.....if u do that u can be on the mag cover for sure!:D

[siba]

yer sounds sik but itd cost like 10grand so i dunno wat to do! i love revin the car past 5000rpms n just watching the tacho go from slow to fast but i love the sound of the turbo so anybody no what i should do ill have bout 5-7grand to play with

cheers

[egSi]

get a turbo kit man and then a turbo cam, gear and springs retainer, thatll eat up that budget pretty quick if u want LOL.

this sounds good... going back to the old skool days of vtec... small capacity and all about the revving hehehe... making me tempted hehehe...

[michael_antoi]

well, turbo would be the cheaper option to gain hp

to gain that amount of hp and keep it na would cost more, but that means it would be na and thats always good.

[freakygeek]

Why would you want to stroke an engine that already has a very long stroke for its capacity??

A D16A8 has 75mm bores and 90mm stroke. This means to stroke it further would make piston speeds ridiculously high and the engine wouldn't rev well.

oi get back to modding C-RSX :D

btw a good point - but , increasing bore in sleeveing and larger pistons would have a similar ( but not increase as much) effect in increasing displacement true ? And , leave the stroke alone ?

[michael_antoi]

could someone explain to me the difference between boring and resleeving?

just a little confused here...

hahaha, I lurk around these parts occasionally. :)

According to some website selling Darton sleeves etc they say 77mm is maximum bore. So the increase in capacity isn't much.

Just bolt in a B series and be done with it :D

[bennjamin]

yup that 2mm per piston is hardly worth it... from 1590 cc to 1676 cc



hope i got the (PIE/4)x bore 2 x stroke x No of cylinders correct :)

Close, but no cigar...

Try this for reference, something I just put togehter...:

http://b16a.kicks-ass.net/ProECU/engine calcs.xls (http://b16a.kicks-ass.net/ProECU/engine%20calcs.xls)

Parameters need changing to your specific engine details.
NB: Total Swept Volume is the Engine cc's

Amongst other things, this is also a good tool to simulate effect of bore diameter and stroke changes on Swept Volume.

[bennjamin]

cheers for that - if i had excel etc id open it up and have a peek :)

regardless , I think we can all agree for the money spent , increasing the displacement of a d16a8 or perhaps any D series is a waste of time and money.

I'm with freaky geek on this one. Forget stroking. Strokings for V8's (that's what I reckon anyway). Stroking will probably lose you revs anyway and the best bit about hondas are the revs. If you want displacement increase, bore it. In my overall opinion though, if you want figures, turbo, but if your like me though, go all motor. I like being able to beat V8's without a turbo cause the look on people's faces when they find out there's no pump is classic.
