im thinking about putting a d15b in my car and i wanted to know more about it, is the block just like other usdm d15b? Such as oil pressure, bore X stroke, etc etc
thanks for any replies

 

yes, they are the same - be careful when getting D15B - there are 3 versions - the normal VTEC, a 3 stage VTEC and an economy version which is only about 90hp

 

how could i tell the difference?

 

the 3-stage VTEC has 2 VTEC solenoids, doesn't say VTEC on valve cover - the VTEC-E (economy) has smaller intake, doesn't say VTEC on the valve cover

 

Does it have to have vtec on the valve cover?

so would i get same results from complete d15 vtec and usdm d15b2 block with d15 vtec head?

 

I have a boosted d15b jdm vtec. They are alot of fun. you never gonna get power out of them like say a b motor. but if your goal is 200hp then it will be fine.

 

what head does anyone think would yeild the LEAST compression on a d15b7? wheres mista bone when i need him

 

Lest compression would be the NON VTEC heads.
The JDM D15B SOHC VTEC has stonger and longer rods than a standard USDM D15
same length as D16 rods, BUT THE D16 and D15 RODS DO NOT INTERCHANGE!!!
Think of the D15B SOHC VTEC as a USDM D15 prepped for higher revs.

 

does anybody know the name of this kinda vtec...it activates by oil pressure ( read from some web ) so would d15b2 block be better with that vtec since its got 24 extra psi for oil pressure???

 

i dont see why your worried about the difference in oil pressure. All vtec motors engage the bigger lobes using oil pressure. (B,D,H,F,K series)
