Re:Any jdm d15b's boosted?
 

ahhh i see u go to www.boostn.com as well ;) im from PA and met the the owner, hes got some good deals on there. I was really impressed with the d15b stock b4 i did a nos setup then turboed it. I dropped it in my 93 dx coupe and with header, intake and exaust was able to pull down 14.9s and low 14s with a 55 shot. Havent ran it with the turbo yet, still needs a few more mods and tuned even tho it might be sold soon. :-[

Re:Any jdm d15b's boosted?
 

So far I've been damn pleased with it (for the price) On my old JRSC setup I ran a 9.11 in the 1/8 mile down here in FL in the heat of the day. Never took it 1/4 wish I had. Strong revvin little engine she gets real happy in them upper rpms.

god i love del sol seats!

Re:Any jdm d15b's boosted?
 

How are your guys crank case vent system working out for you guys with that filter on the valve cover and stock pcv?

Re:Any jdm d15b's boosted?
 

I have a filter on there right now.. Gets a lil bit of oil in there everyonce in a while.. I have been just cleaning it out once a month. I plan to get a Greddy catch can and run one hose to the valve cover and the other to the intake side by the filter (not pictured).

Well I am... sort of. :)

<~~~ jdm d15b , 5.5 psi.


tdo4 turbo/ uberdata p28


bad ass lil mo'ter

Re:Any jdm d15b's boosted?
 

;)I bumped my boost up from 5psi to 10 tonight.. and WOW.. its like being turbo all over agian! You wanna put a big smile on your face? turn the boost up a lil bit ;D

Re:Any jdm d15b's boosted?
 

i got 9psi on my d15b in my crx. car runs incredibly hard. im getting dyno numbers on Sat, so ima post em up. im thinking 240+ whp for this one, the car is running extremely hard. i blew the doors off an Evo8 the other day, i shifted 2nd on him and rode 2 cars on it in just that gear.

i did make 130whp all motor, IHE w/ lightened flywheel. at 4.4 psi the car made 190+whp, the dyno was shut down 1000rpm too early on that one.

i will return with a dyno chart. d15b is the best d series since the dohc zc.

Re:Any jdm d15b's boosted?
 

does d15b got better rod to stroke ratio?

but does it have weekeer rods then z6?

crower is the only one that make aftermarket rods for d15?

Re:Any jdm d15b's boosted?
 

#1 Yes which makes it quicker to rev and happier :)
Compression ratio 9.3
Bore, mm 75
Stroke, mm 84.5

Also keep in mind it has a lighter assembly due to the rod journal size. The journals are the same as a D15B7 which makes the crank lighter as well and results in easier, higher revs for longer periods of time with less stress and wear.

#2 No the z6 and d15b have the same thickness of a rod.

D15B on the left, D16Z6 on the right

#3 Yes, unfortunatly due to the odd sizes they need to be custom made. Maybe with a higher demand (when people realize how potent these little 1.5's are) someone else like Eagle will produce econo rods. Most people run stock internals and never build their engine up. Lets keep this our little D15B secret as they are much easier to find these days and has far less abuse on them. While it does give up 100cc's to a Z6 it puts out the same power rated at 130ps or roughly 128hp (figures at the flywheels before the frictional losses of about 15-17%)

Re:Any jdm d15b's boosted?
 

difference in displacement isn't that big.

d15b = 1534cc's
d16z6 = 1594cc's

:)

you mind measuring the length of the d15b rods? there really aren't any OEM replacements are there...?

Re: Any jdm d15b's boosted?
 

;D long live the good old d15b! i am working on 1 to replace my d15b7, im just a bit concerned on the 9.6 cr might not wanna go past 10psi and tune it just right :6 this bitch should fly. currently the d15b7 runs pretty damn good on 5 psi ---- 2 gears the needle gets to 60 pretty damn quick, i absolutely love it i wanna go 8 psi soon im not expecting this thing to last, the b7 has to go soon lol :-*

Re: Any jdm d15b's boosted?
 

I got one na in my 88 crx si and I ran a 15.4 quartermile, thats with only an intake and header a6 IM manifold and stock exhaust with cat, and wheelhop'n like a mofo. Their not bad little motors

Re:Any jdm d15b's boosted?
 

The main journals are 45mm like the D15B7, But the rod journals are 45mm like all of the D16 blocks.

Re: Any jdm d15b's boosted?
 

Can use any 1.6 aftermarket rods. Just gotta notch the block like normal.

Re: Any jdm d15b's boosted?
 

Im working on a usdm b7 block/ jdm crank combo. I was wondering if you guys had any suggestions for rod/piston combos?
