anything on a d16y8 sohc?

whiteracer · #1 08-08-2003, 04:29 PM

i don't venture into this forum too much and it's about to show. So far on my 98 Ex i have a dc header, aem cai, and an apex'i cat back. I know that's the basic mods and allows the engine to breath easier. But after the stock 127 hp, and those few mods I ain't gonna be able to put up some big numbers. I know swapping in a b16 would be a lot better and quicker, but seeing how this is the y8 i was wondering if there is anything i can do to on the stock internals?

I love you for asking. I ran a 14.012 1/4 at 8psi with just the Greddy kit, BOV, FMIC, and exhaust. The rest of the car was competely stock with over 40k miles. Turbo's kick ass.

yeah the d16y8 is the strongest of D sereies motors and I have a turbo on mine and it will beat any stock b16 out there and its cheaper. Its pretty reliable but will need internals after awhile and a new clutch.

If you don't want to turbo off the bat, the Y8 head has the most options for cams of any of the D-series motors. Maybe get a CRane Cams camshaft, and some new cam springs an retainers. That should add you up to about 15hp As for turbo, Edelbrock just came out with a new turbo system (about $3500 street retail though) that boosts power to 170 at the wheels they claim. Not too shabby for about 7-8psi of boost.

hmm....
a stock y8 has a whole 127 hp. Off of that turbo on a stock motor it would go up to 170? and I kinda like my I/H/E so the cams are tempting. What do you think if i eventually had both options there; the turbo set up and the camshaft, retainers, and springs. 200hp? i don't see that happening on a d16y8. Well, at least not on my budget. Numbers even close to would require massive tuning; and i'd still like to keep this as my daily driver. :starting to look into the nitrous option now:

you would definatly want to build the bottum end before the top end with a turbo and building the bottum end your lookin at a lil more over than 200whp. All depending on the boost also to.

Don't do nitrous, it wouldn't be worth it unless you only spray at a track. I'm not sure if nitrous is legal for auto-X either.

If you get a port and polish, the cam, springs, retainers and that such, I don't see why 30hp gain wouldn't be too far off. Maybe like 25hp is closer to what it would be. You could push 200hp with a D-series, I've heard of 215whp tuned D-series motors, they were stroked from 1.6L to 1.9L though. Once you're at the point to need new rods, that's about when you might need to sleeve the cylinder walls for strength as well. That can get expensive. 150whp is obtainable for about $2000 in a N/A setup on a D. Check what I sent you in the PM I sent, and see what can be come up with for answers.

I've seen 320whp and 276tq out of a D16 @ 16psi with stock internals and a 2mm headgasket.

If I was gonna do it all over again, i'd build my motor from the bottom up and go turbo, and this is coming from a guy with a supercharged D16Y8.....

That's about the only way to build up a D-series for significant gains, from the bottom end on up. Unfortunately doing that can be so expensive. But like a intriguing quote I once said saw;

"anything a B-series can do, a D-series can do for cheaper..."

That is true though! Bisi Ezerioha, 10.70 second quarter mile all motor D15 (NOT D16), what more do B-block fiends need to know? And they say it can't be done. Pfffff...

I've still got other things for my car on higher priority than building up the y8 (koni yellows, skunk2 camber kit, and other suspension junk) but i do need something to add to this list of "things to get soon" regarding my engine. I kinda just stopped at i/h/e but being able to put numbers up like those is quite tempting. So for now i just need one things i should buy and install to get me started off with, something to add to this wish list, any suggestions?

Redrunner · #12 08-12-2003, 10:33 PM

Yes and what about those d16y7 those are really good the best lol

97HondaCivic · #13 10-20-2003, 09:19 PM

Ive got a d16y7 with a y8 head and ex computer with turbo. I just havent stuck it together yet and i was wondering would that be a good combination. I plan on getting a camshaft and some other stuff once i get some money

just wanted to say that if you are going to eventually put on a turbo, you dont want to get a cam meant for NA. youd be better off to get a turbo cam(high lift/short duration) to go with boost, but if you do that before you get the turbo Id think your power would go the opposite way. so do them both at the same time or the turbo first IMO.

and what cr would that D be running with a 2mm head gasket. also isnt that the cheap way to lower cr, and if you got the money to spend ot get 320WHP, why not lower it the correct way. and on the B18b, hondas engine that can take about the most boost stock, I havent even heard of 320WHP on a stcok B18B.

if you are gonna turbo- sell your header and get the greddy kit. ive seen cars break into the 13's with greddy turbo kits on d16's. dont boost more than like 8-9 pounds on stock internals, keep it at or a little under 200 whp for rod safety. if goin n/a, dont port-polish, cause its like well over 500 bucks- raise the compression before u do that. look into edelbrocks new y8 intake manifold- ive seen it dyno gain 5hp on a y8 with i/h/e. crane cams are expensive- check out the zex cam made for the y8. if u get the 53900 its made for the z6 and u have to advance the timing 4 degrees. all motor is expensive, trust me. im just about done with my all motor z6 build and for the money ive spent i could have a bad ass turbo setup. thank god i got a little of the happy gas to help me out when i race.
