tryin to decide on a d16z6 or a d15b7 let me know what you guys think would be better to do a all motor build up on

northkai3

well the d15 is a better motor but less parts for the smaller block and the d15 makes 3 more hp i think

vsmhatched

ummm a d15b7 is a 1.5 non-vetc motor that comes in some DX's. Single cam vtec motors are the d16z6, d16y8 or the jdm d15b. I perfer the d16z6 for single cam build up. But thats my opinion.

allmotoralldayeveryday

ya i no its the d15b dunno why i hit 7 lol

junior40er

Nah, use the JDM D15B motor. I had both d16z6 and d15b and d15b is much better than d16z6 hands down. If two hatches race, one witha z6 and one with a d15b the d15b will win.

i also have the jdm d15b in my cx hb but just out of curiousity what did the engine originally come out of in japan? was there a regular si in japan besides the sir ? i would imagine so but im not sure. Also when looking for parts for my engine what should i look for cause i know that some of the parts are different between the mototrs for example would a cam gear for a d16z6 work with my engine or what about pulleys? im not sure what to look for for certain items

forget both...I have a jdm d16a out of a 92-95 del sol....best runnin single cam I have seen...

All motor SOHC is extremely difficult to make power with.. be prepared to spend a TON of money on nothing

KPNitJDM

not really..I have some ignition stuff, crower stage 2 cam, milled head, full exhaust, and skunk 2 p30, and most dual cams can't keep up...but all you dual cam ppl can sleep on a single all u want, but then you're just as bad as domestic guys for underestimating any honda or any other import for that matter. How many times do they get beat? thank you. So watch who you sleep on cuz thats when you usually lose a race......

HAHA!!! Thanks for the laugh bro, that made my day.

I've personally driven both the D15B VTEC and D16Z6 in the same car (D16Z6 was ran low on oil, then replaced with D15B VTEC) and the D15B feels weak down low.

When you're starting with a one cam disadvantage, you want to take advantage of every little tweak you can, such as the extra displacement of the D16Z6.

I'd build a D16A6 non-VTEC over a D15B VTEC. In fact I did, and it will assrape the D15B.

d16a6 is a strong bottom end....anyone see that write up in I think honda tuning on the crx with the old skool single cam with twin carbs puttin down over 200whp?

d15b7 is not a better motor and is non vtec

hahahahah well dude i will tell you... it really matters on the driver because i have smoked gsr powered hatches with my single cam at the track a few times... i honestly prefer the d16z6 because its legal theres no smog **** u gotta worry about when u put it in your car... also the z6 is stronger than the y8...

the difference between the z6 and the d15b is the cam and the displacement.. but if you put the d15b cam in the z6 youll be faster

Calvinator

There is a thin line between the d16y8, d16z6, and the d15b. They are very alike, performance wise. I agree with bauley that the 1.6s have that little extra punch in the bottom end, but the d15b seems to rev a little more free. I have own all 3 motors. Anyways, go with one of the d16s, because its easier to find aftermarket rods.

northkai3

so what all u are saying is d16z6 block + jspec d15b head = best combination

No, just add the D15B cam, but IMO it's pointless trying to find one for the minimal gains.

I'd simply get the D16Z6 and add any aftermarket cam of your choice at a later time.

northkai3

although the d15b does make more hp 3 i think i regret only for the lack of parts but either way getting a new engine is not my priority right now i still have my motor on my cx tranny! lol but i hit like 120mph in third haha

northkai3

im getting my new tranny and installing my new flywheel and clutch next week

lshatch1.8

just boost all those d motor i think its pointless to do an all motor d maybe even b! boost is where its at d+pistons and rods+boost= WALK ALL OVER ALL MOTOR

ok sure just let me know where i can get some good high boost pistons for my jdm 1.5 block

allmotoralldayeveryday

right now i got a d15b7 non vtec in the hatch but im tryin to figure out if i wana boost that or get a d15b or d16z6 i can get the d16z6 but wich one would be better for the boost we put a turbo kit on my friends d16z6 and it ran good he had the cx tranny to it ran pretty strong but he had a couple problems with it but then again he didnt get a fmu or any fuel managment **** either

allmotoralldayeveryday

every one i no with turbo has problems when i had my b16 and neptune in my integra i never had one prob with it if i could afford it id just get another b16 and throw it in the hatch but i gota work with what i got right now im thinkin of just throwin the d16z6 head on my d15 block and neptuning it but im not sure yet
