Limits of d16

[gjcivic]

Ok, I know this is kind of a dumb question, but what do you guys think the limits are of a built d16???

I heard that d16's are pretty much free if you can find one. So I was thinking that I should maybe get my feet wet boosting a d16 before I dump $3000 for a swap, just wondering If any of you think it would even be worth it.

I know of a d16 at sea level with stock internals running 12 psi on a supercharger with a 50 shot of nitrous. I think he finally blew the motor on a 90 shot. It seems that those motors deserve more respect than they are given. there are some pretty fast turbo and SC single cams running around.

Just cause its a single cam doesnt mean it cant make mad power. Learn porting and port the head, and install some turbo grind cams. Then Boost the hell out of it.

Wouldn't be a bad idea but might put you over $3000 to do it right.

I'd say about 190-200hp with a sohc turbo kit.

[2000SiVTEC]

there are actually some quite fast sohc cars. They deserve respect adn you could make more power for less money than a swap would cost you, IMO at least...

I think you'd be better off in the long run spending the 3 grand on a swap instead of a turbo kit. Better reliability and a better place to start for your next round of mods. D16's can be made fast but it takes a lot of cash and in the end a b series motor will be faster.

Exactly why I change the motor out :) Nothing like have a little hybrid ;)

I'm a Mitsubishi guy and even I know the swap would be the more productive way to go. Do the swap and then later go with forced induction.

I have a d16, it's twin cam now but it still makes 125hp with 108 ft/lbs and that's all motor and to the wheels!!! I plan on getting my roomies turbo and running 5 to 7 lbs of boost with no intercooler for a while, then 9 to 10 once I have a front mount. I agree with the "under-estimated" comment, but I also agree that just a b16 swap will yeild the same power numbers stock as my highly (very highly) modified d16......so the choice is yours. Also any of the B series motors will have much more available and the limits are endless. Chad and Lisa have made over 500hp for years now!!!!!!

Take into cosideration that the D series motor wheighs a lot less than the B series and especially H series motors. The power to weight ratio comes into effect. You gain 33 hp if you go with a US spec B16 (160 hp) over the D16Z6 (127 hp). With the approximate increase of 125 lbs by swapping in the B series you almost end up running the same 1/4 mile times, maybe a 1/10 th faster.

[TedR719]

How do you figure a 1/10 off the quater mile? if we are swaping in the same car...

I went from a best of 16.69 (d16) to a 15.86 (b16)

if something ever happens to my B20, I'm going single cam. either crx si D16A6, or another sohc vtec Z6 or Y8. there are plenty of fast single cams around, my friends d16 dx hatch is in the low 14's with a zex 75 shot :D

single cams are cheap, and easy to find :)

[gjcivic]

yep, thats what I figured, about half one boost, half swap. I'm just thinking that if I'm going to be playing around with boost, I'd rater blow my d16z6, then decide if I want to rebuild stronger, or step up to a swap, and use the turbo on the new motor. Just figured it would be better to blow the d16 that I have instead of a b16/18 that I just spent more money on then a turbo would have cost. I already talked to theflyin miata guys about helping me ttune on their dyno. They have a little honda experiance, but a LOT of boost experiance. Ad they have a Wideband :)
What do you all think about the Greddy turbo kit. I've heard it isn't god for a whole lot of boost (maybe 8lbs max), but its cheap.

[ZCHybridCivic]

I have a spare D16Y sitting around just in case I get money someday I'll build it for turbo/NOS. Or if (heaven forbid) my motor pops I'll have spare parts. You are correct about the Greddy Kit, the turbo is very............VERY!!!!!!! small and that limits the mount of boost you can effectively run on it. Just ask any DSM guy how small a T25 or T28 is.........If you want a good picture of one, there is one on the home page for PFI, that pic is a T76 vs a turbo about as big as the Greddy one, but you can always upgrade the turbo itself and then you'll already have all the parts and most of the work already done. Besides, you won't want to run more than 9lbs or 10lbs on a stock motor anyway, unless you like trailers-----> from the track.

[gjcivic]

I think I've pretty much desided to go the greddy way. at least I can build in stages... turbo, tune, IC, tune, bigger turbo, boom, new pistons and rods, tune.......................................and various other parts in-between:) Now I just need to have a huge yard sale and sell off a bunch of my wifes junk....errrr, stuff.

Way I see it, my car is a blast o drive now, just addinga little boost should just make it thatmuch more fun.

$1300 Greddy Kit on SOHC vtec is faster than a b16 anyday. $1300 vs. $3000. No question

MMMMmmm, I've heard otherwise, but I hope so. Hopefully soon I'll know for sure...
