d15b vtec vs. d16y8

[d16y84door]

im not new to this site but i am a new member so ill post here, anyways i have an 88 civic hatchback its stock right now, but im planning on a swap real soon, i want to go sohc since im on a small budget, but im trying to decide on which motor i actually want, my buddy has a 91 civic four door with a d16y8 that isnt even hooked up correctly, and the vtec does not work, and its still a pretty quick little four door for only having intake and exhuast, but then ive read about the d15b vtec and ive been told that its got a better cam. i guess what im trying to get at is which motor would be best, and are there after market parts to support the d15b vtec? any info would be great!

to be honest with you.."most" parts for hondas are pretty generic when it comes to 1.5, 1.6 liter..especially since both motors you speak of D series engines. theres so many parts available for hondas: intakes, intake manifolds, headers, fuel pressure regulators, fuel rails, valve covers, suspension mods, i could go on! alot of honda parts are interchangeable and you should have no problem sourcing parts for your civic 4 door!

personally, i would prefer the 1.6 liter because there's no replacement for displacement. and also, IMO, the 1.6 liter sounds better than the 1.5 liter.

wiring up your VTEC shouldnt be a big deal, i believe we spoke about this in another thread already.

im sure we talked about the vtec, im heading over to my friends house around 3 o'clock so ill find out if hes got the ecu, but im trying to find out everything needed to wire up the vtec, is there some kind of shop that could do it? how much would it cost? stuff like that.

anyone that is familiar with motor swaps and such would have no problem hooking up your VTEC. best thing to do is build a relationship with a local certified reputable mechanic. send him business, he'll take care of your problems for dirt cheap. i would talk with your local friends and see who owns the best service shop in your town.

Ok... My own personal experience of the D15B VTEC (just swapped it in a week or so ago)...

I honestly LOVE it so far... Once I figured out how to make VTEC work (oil pressure was too high I assume, too much oil), and when I get it on it in high RPMs its quick! Definately a better engine in the high RPM range than the D16A6 (stock CRX Si engine)... It just seems to love the high RPMs too, and revs oh so nicely... No hesitation or anything... And it idles so smooth...

The negatives... Now the downside as JDMEFSiR pointed out, this is a 1.5 liter engine, as opposed to my old engine that was a 1.6, so there is a little bit less low end torque on this car... And I can most definately feel the difference! So to keep up in traffic, I have to rev the engine higher than normal... This isnt too much of a problem for me tho...

Conclusion is, would I do it all over again? Yea, I probably would... Its definately worth what I put into it, $1200, countless hours of research, and the week actually installing the engine and going without a car for that week... Its definately nice... The best part about it is, I have more power, and with the amount of stuff I replaced, I should be good for another 60k miles atleast without any problems... I hope anyways, but u never know, but having a newer engine and new shit replaced does give u sense of security...

Now the whole D15B vs D16Y8... I dunno... The Y8 is a newer engine coming from a 96+ car... So less miles is a probability... Plus its a domestic engine, so parts arent a problem... The D15B does have alot in common with the D16Z6, but it also has its own part numbers that would be impossible to find in the U.S... If I could find one cheap, I probably would go with the Y8 and an OBD1 setup...

damn! very well said exempt!

Thanks...

And I am in the process of making a write up, basically highlighting the differences of this swap from the Z6 swaps that are pretty documented... But this is for an Si, so a DX will be slightly different...

y8 Would be the best choice.. a couple of little inexpensive tricks would make u go fast.. upgrade ur cam for a better intake lift a high rpms..complete msd system and a chipped computer with the JUn program and ur good to go ready to kick some SI ASSES

[Exempt]

Uh... This post is over a year old bro...... BTW, just about anything that you can do to the Y8, you can do to the D15B... Specially the things you listed: Cam, MSD ign., chipped ECU with a JUN program, ect...


The only real downside to the D15B is its displacement... But not really that big of a deal when your swapping it into a light car anyways...
