I'm in a situation where I find it hard to sleep at night. I've seen a lot of other people in this situation recently, but not many solutions. More and more people are becoming interested in building d-series, so I wanna get an overview of how many people would rather build their d-series or swap in a b. Of course this is all for turbo. Thanks.

 

If your power goals are under 250whp, build the D.....they are an inexpensive motor and have great potential. If you desire to go much above 250whp, it will cost you just as much to modify and build one as a B-series. Also, don't forget the respect factor. An 12 sec. SOHC gets WAY more respect than a 12 sec. DOHC.

I dont know how build a 12 second D is harder than build a 12 sec B ???

 

It depends on how far you want to go with it and what your future goals are IMO. If you plan on doing one or the other then leaving it alone then the built d will be faster and the more cost effective route. If you know you will probably be wanting even more power down the road and will have more money later on to budget towards your car then the b has more potential if you decided to build it later on.

 

Will this be a daily driver? I'd take the B series, more torque.

care to explain ? the long r/s ratio on D series usually makes for some very good torque...

 

I've been trying to decide this for like half a year now. I think maybe I'll swap in a B (B18a1) and put a decent turbo on it. Hopefully get like 250 whp. Then when I graduate college in 2 years build it. Yes this will be a daily driver. Which would be more reliable? Stock b turbo'ed or a built d turbo'ed?

Exactly. He has no idea what he is talking about.

 

go b series turbo. youll be happy with it. trust me......

By "long" r/s you mean LOWER rod ratio, correct? As in normal rod length combined with a "longer" stroke... My advice would be B series and only B series... 1.58 from the B18C is perfect for both worlds (reving/power), I wouldn't necessarily go higher (except the K20 at 1.62) or lower... I've never driven/riden in a SOHC turbo car but after you feel what 600whp+ B18C feels like I don't see why you would even consider anything else Just my $0.02

 

well if you don't mind downtime, you could buy pistons, rods and resleeve your motor and the whole deal for under the amount of doing say a gsr swap at retail price. then you'll have a bullet proof motor and be capable of some sick *** numbers

but downtime will be a bitch for sure

 

my d15b vtec rod/ratio is 1.62, just as good as a b-series, K20 as well.

After you feel 475 ft lb of Tq. at 5000 rpm and beat "600hp+" B-series race cars, you may understand why someone would consider something else

matt, i didn't know you bought a camaro!!!!!! lol.

 

If I had it to do over again I would have a built turboed d series rather than a soon to be turboed stock b16.

 

Build the D. I have a fully built D series motor in my 95 EX as well as turbo. The torque is unbelieveable and HP #'s are very good too. Their was a post on here earlier from some performance shop in VA that produced 395 WHP out of a SOHC with a 50 trim turbo. Dont let anyone tell you SOHC's have no potential because that is BS.

But you had to use nitrous to make that power and 10.85 isn't that good for being in a Rex, Brian's B18C/EJ6 is daily driven, full interior, only makes ~560whp 350wtq (no nitrous), and is just as fast as you but pulling a much heavier car... Yes, power isn't everything but still but which has more potential in the long run???

EDIT: FORGOT TO MENTION, HOPE YOU'RE TALKING ABOUT THE REX AND NOT A V8,

 

Depends on how much you want to spend. If you go for big power on a b-series motor you will have to spend a shitload of money just to make the power streetable. i.e. axles, lsd, endless suspension....600fwhp just doesnt make sense unless you can put it to the ground. A 300hp d-series will walk on a 600hp b-series if the b-series cant hook up.....just my .02

 

im looking to go well into the 12s on my d series build and should be around 300 whp. i say go fo rit. for the cost of a b series swap my d series is ready for 20 lbs of boost.

there she is, a a6/y8 mini me fully forged balanced ect waiting to be punished under copius amounts of boost.

im not trying to flame but even tho nobody has said that d series has no potential... they are just saying that b series has MORE potential.... im sure this debate and many other will get squashed as soon as more and more ppl will get k-series motors. i have already heard as much as 375whp with k series. but that is besides the point. anyways back to the subject.

on the real a d series build is cheaper than a b series motor... i dont doubt that.... but in my case i went b-series because i knew that later on i knew i would have gone b series because of its potential is much greater than d series.

if i would have only wanted 250whp in the first place it would have been cheaper to go d series turbo but i just knew from the begining that that is not what i wanted. so basically what it comes down to what you want... 12's,11's,10.... all motor, boost, cheapests, whatever.....

 

Build the D, you'll get a lot more torque

 

do the d!

 

b- for sure

 

Anyone have any specs of a Built Turbo D Series, Im picking up a y7 soon and i want to build it, but then i need fuel management, this is going on a dayily driver.

I was replying to your questioning the senses of someone that would consider building a D after experiencing 600hp plus of B series power. I was just poking a little fun. I hear comments like yours all the time. The fact that my engine uses lots of nitrous really doesn't matter....hp is hp, however you make it. I am suprised that you don't think a 10 sec CRX is that good. How many street legal CRX's, or Civic's for that matter, are in the 10's in the country, less than 40 I bet? But, I will agree that the B-series engine has more potential. But, in the real world there are very few racers taking full potential of their engines.......
