Is there a difference in throttle body size from a JDM D15 to a USDM SOHC Si motor? is the D15 throttle body at all bigger? How mnay mm thanks.

 

i will like to know too.

 

I'm almost 90% sure the D15 one is bigger but I would like to no for sure, anyone?

 

bump.

 

The last JDM d15 I put into a car came carbed. So I couldn't answer the TB question. But I know it sure was a lot more power than the standered US d15b7.

Was it as much as a d16z6??? Hmmm hard to tell in the butt dyno, as I love the vtec and rev's.

 

JDM d15B sohc vtec (not vtec-e or carb version) rated @ 130ps.
it uses basically a VX bottom end (for better r/s ratio), and top is comprised of P08 head which is just like rhe D16z6 head. Intake, TB, and the rest is identical with a exception of the cam which is slightly more aggressive and 4.5 degrees retarded when compared to z6 cam (due to block height difference).

You're the man bro when it comes to the little nuances of the D motors.

 

thanks tom....mista bone has been a great teacher ever since '98 on the old hybrid board (AJK then)

also then for the name change above the avatar

 

Yeah Mista Bone is the man too, but he rarely posts here any more.

 

sometimes i dont blame him for not posting here... until just recently there was no love for the d series. everytime he made a tech post some ignorant fool would post some crap about swap this, d series suck.

after years of listening to (reading) junk... what would you do?
probably migrate to the dseries forum, where his knowledge is appreciated.

 

what would u guys consider the better motor in the way of performance?

 

What Lip is that?

 

Well, I would say the Z6, if for no other reason because they're plentiful & cheap, and you don't have to pay the popularity tax on it just because it's from JDM Land.

Edit- Way off topic, but iluvjasmine, your avatar is a cutie
