Ok, so i've done a search and found all of about 2 things..!!! I realize torque is the key to power, and i've heard that of the single cams, the D15B is the best motor to use to try and make into a torque monster... And i'm not switching to dohc, so please dont flame up the postline with "blabla sohc has no power to make torque blabla"... Besides basic i/h/e what out there in the realistic world is there to make my motor comparible to the ls in torque... I ride on LS's anyways, but from what I hear there best to use for torque, but I have jdm d15b so were gonna just work with what I got.... Thanks Guys.....

 

To be anywhere in the realm of a "monster" I think you'd have to have a pretty good turbo setup. You Mentioned I/H/E though, so I'm guessing you're wanting to stay NA. In that case I don't really have much to offer. Bump compression I guess? Someone else will probably chime in with something better as far as NA goes.

 

boost the **** out of that thing

 

LOL. A 1.5L will never be a 'torque monster' even if you boost it. You can make decent power but your peak torque is always gonna be high in the RPM range. If you want big low end torque(for a 4 cyl at least), forget about the LS - get an H23 or F23. They aren't expensive.

 

As far as staying N/A, that wasnt every really an issue.. I mean i'd love to go turbo, but I also realize my car is daily driver, how much can I actually boost the **** outta my motor and also drive it 100 miles a day...??? On stock internals that is...

7-8 pounds maybe. all depends on ur tuner.

 

fuel wise on a d/d turbo do i need to get an fmu, injectors, possibly fuel rail and anything else... "besides turbo, intercooler, wastegate, bov, ect.."

Glad I'm not the only one who laughed at the words "torque monster" and "d15b".

 

And i'm glad you wasted your time to actually post something Way to show the love...

F23 owns your d15. if you want torque you need displacement. If you don't have displacement, you need boost.

 

yea you aren't going to get torque out of a d15b, it's just not gonna happen. Even if you turbo it. If your into torque, especially low end torque, you need to move away from hondas.

 

You'll never get above 150 ft/lbs NA. &lt;- And that is being very optimistic. The best way to get torque is more displacement. Just try to be realistic with your goals.

 

I said i'm trying to be realistic as possible, and only came here to ask you guys opinion because I figured someone has had to try it before... I've seen some pretty sick turbo d's out there... And as far as F23, who really does an F23 swap..?? I've never met anyone waste there time doing that, if im going to go through that headache ill just get a dart block and boost 60 psi's, probably be a little more powerful But back to the realistic realm, i dont have 5 g's for a dart block and i'm not going to swap an F23 in my car...

 

you should search for topics by bisimoto, and look at what his F does. Granted it is FAR from stock, but damn is it quick.

Come visit Earth, where one of the fastest All Motor honda's on the planet is powered by an F series SOHC motor.

 

I suppose if you lighten up your chassis and upgrade the D15, maybe the lightness of the car with a little torque will give you that "feel". I mean, a 13 second feeling is a 13 second feeling, whether it is achieved by a Viper, a Civic, or a bike, right?

So in your case, I think you also need to focus on power/weight ratio.

 

I really don't think the words "torque monster" and "D-series" should be in the same sentence.

You can make power, but it will be crazy shy of being a torque monster.

 

Bore/stroke that biatch.

 

Yeah see, now were on the right path... Preciate it bro

No need to get butthurt about it. Read what you are asking. You want to know how to make great torque out of a 1.5L SOHC engine. Obviously, your displacement isn't going to do it, so either bump the cc's or go F/I. It's just ridiculous to think a d15b will ever be torquey, especially given the myriad engine choices a Honda owner has.

The performance mechanice down the road put an f23 in his drag CRX. Guess what, with mild tunning and work he puts more power to the wheels than a stockGSR (dyno to dyno). He spent much less than a GSR swap and Oh yeah, he is also N/A.

 

Wow I never knew that people actually do f23 swaps, to me it seems kinda pointless since you could bolt in an H22/23 for about the same price.

You learn something everyday I guess.

To the original poster, the most realistic way that you'll even get close to being a "torque monster" is FI. Boost that crap with 7 psi and get good tuning and you'll have a fairly reliable daily beast.

There is a guy who drags with a NA D16, I think he is pushing low 12 seconds in a 5th gen hatchback. But that car's chassis is redone with 1 piece front end and the whole 9 yard. I don't think that car is streetable but it shows that the feeling of a 12 second can be achieved when you pay attention to weight reduction, and tires, and all the other things.

Good luck.

H series has FRM sleeves, F series has iron sleeves. iron sleeves &gt; FRM sleeves.

you can pick up an F series for wayyyy cheaper than H series.

IMO, that is a huge waste of money. whats the point? bragging rights? you can do 12s in a stock chassis with full interior if you just make decent power. it'll be cheaper and easier than redoing your chassis. why stick with an NA D series? makes no sense
