Need Professional help, I wanna know the limits of my D15 block
I have to start with saying that Im so glad honda-tech exists. I have done month's of reasearch on this site and Ive seen many issues come and go and some still interest me. Now Im about to be ready with enough knowlage from this site, my school, and tuning my current D15b7 (95' Lx), to start building a killer street motor,
Having said this, I want anyone that has had expirence with this motor to post what they have done and what Kinda limits they have reached or how far they have taken it. Ive been throwing the Idea of a boosted stock block with ls rods and mabey an A6 head on it, Or a mini me with a Y8 head and IM with stock bottom end, mabey good rods depending on budget.
I know this block had one very good strength, the main gurdle, not bering caps like similar motors, not even b- series (correct me if im wrong, Im not always right) And I also here they have great rod ratio's.
so if anyone wants to jump on this topic then please do, I know I could go D16z6/y8 , but i have some faith in this b7, Help me out.

either see Billy/Forcedsol in your KY, or contact me.
LS rods will never work in a D15 block, ask Billy.

Re: (SOHC_MShue)
If you wanna stay NA notec B7...best mods at this point in time are bolt ons and a camshaft...don't worry about ur block unless you plan on boosting it

Really? Bisi will **** on your "gaurentee"
People don't seem to understand that VTEC is fairly useless for racing. If you are spending all of the time in the upper powerband, there is no need for 2 camshaft profiles. You just put an agressive camshaft in the B7 and you are all set.

Re: Need Professional help, I wanna know the limits of my D15 block (Broke@$$tuner)
Ah, another D series fan...or budget racer, either or, it's all good.
The limits of the stock engine (D15B7)? Heh heh...not all that bad if you aren't looking for the ultimate go-fast-in-a-straight-line machine. If you want to drag though, I definetely recommend a dual cam with boost...that, and at least a "1 way" LSD.
ANYWAYS, as far as a street car or balanced out tuned machine, the D15B7 is a good motor, especially for beginners. Parts are cheap, plentiful, and there is just so much room to work in that engine compartment. All big benefits when it comes to fixing it up.
A D15 with a good Limited Slip Diff. (hard to find, Quaife?), Clutch and Flywheel, and Suspension/Tires makes the car and chassis confidence inspiring. In my opinion, the D15 only lacks a good Ex.Mani. Basic items like a Cam, larger Throttle, bigger displacement (i.e. cylinder bores) apply to nearly any engine, single or dual cam, so I say Ex.Mani. as the motor's only major oversight from a stock base.
If you plan on staying a car nut for the long run, I'd say it's much better to have a cheaper motor that shares many traits with its bigger brothers (i.e. B18, F22, even engines such as the SR20DE, non-turbo, though the Nissan motor came with oil squiters for the bottom of the pistons...?) to start off.
Figure it this way, blow a $500 motor, it's $500, and you can re-use most of the parts. Blow up a nice B16 swap, near $1800, and that's $1800 again, or a costly rebuild.

B series + boost + LSD, thats about $6000 and still a stock motor.
Built SOHC motor, about $3000 and it runs 10's-11's.
Sorry, I'll stay SOHC and be just as fast.

I love the underdog d-series....for now if your cash is limited get the basic boltons....cai, header, exhaust...then when you get more cash mini-me it with a z6/y8 head...crower stage 2 cam with new valvetrain and you'll have a decent N/A motor

Re: (95excoupeMT)
I always loved my D15Beast7 with simple bolt-ons. I was running 15.08-15.12 when the 99 Si's came out. The best they could muster was 15.6-15.7......I managed 135 hp out of a 102 hp motor with just simple bolt-ons.
"You spent $20K on that?"
Mind you the cars look great, but good looking cars (Hondas fockup!) are not always fast. Sure the B16 is more able to handle boost, which would be another $3k or so. The B16 is best in a 88 CRX HF chassis where it can show it's true potenial.
I don't REALLY hate B's, I hate that I cannot afford them. Therefore I'm a SOHC lover. Simple yet effective.
You have to admit, if your a DOHC owner and get beat by a SOHC, it sucks. But it feels so good to whoop the DOHC with a SOHC. Besides most of the time it comes down to the better driver. I guess being the underdog teaches you to become a better driver and tuner.
Just think what someone like me could do with a B21C5 or a H22 swap.........

To everyone that has posted on this topic, I just wanna say thanks, because this is exactly what I was looking for.
To elaborate on my mods, I already run a cold air intake (home made) a 4-2-1 header, 2.25 exhaust, and I have a new chip sitting in my room waiting to be installed, (any recommended installers?) the chip is just a basic one with upped fuel and ignition curve, with a redline of 9000, like Ill ever rev that high!
With that said, I guess now I need a camshaft to realize full potential huh?
I also considered like a y8 IM and a mild port and polish job with new springs and retainers, but then Im talking money,
The rest of my car, suspension and stuff like that is already taken care of, so any more input will be greatly appreciated.
Keep this post alive,
LONG LIVE THE B7

Re: (Broke@$$tuner)
Yes it will bolt directly on. I forgot to mention that as well. The Z6 tranny has much shorter ratios and will greatly improve acceleration.
FYI: All 92-00 D-series trannies are interchangable

Also, has anyone in here done a mini me setup on a b7, Im sure there have been other d15's done, but I wanna know if someone had expirience on the b7? anyone?
