i have a 95 sedan, i pulled the B7 motor about a year ago and started a rebuild, then found a d15B block for cheaper then a rebuild on my B7 (pulled piston heads out in pieces) i have some questions on the block like,
1)what us model block can i use a water pump and tensioner off of
2)what timing belt can i use
thanks
B7 accessories dont fit

You need the water pump and tensioner to be the same as the block (D15B).
I'm not sure on the timing belt. D15b7 head on a JDM D15B block is an unusual combo. Once you get the pump/tensioner, I'd try your old D15b7 belt to see how it fits. If it's good, then get a new one. If not, you'll have to count the teeth and compare other timing belts that are slightly bigger/smaller.

the block came with a water pump and tensioner i was just going to replace them with the ones i bought for my B7 and realized they diddnt fit. im new to mixing and matching and yes it kind of rare i went with it because i got a good deal on the block but being rare is making finding help hard. Also the timing belt a little loose

if you have a usdm d15b it is from an 88 crx which is what you would need the water pump and timing belt from.
if you are using a jdm d15b iirc i used d16z6 water pump and timing belt on my build
i will probably get flammed for this but i never trust the tensioner on its own i always use a small prybar and go a little tighter then they do own their own which makes up the slack when i used a z6 belt on my jdm d15b

Yeah that's a good point, which d15b block do you have? I assumed it was the Jdm d15b, which is similar to the d16z6.

if your looking at the block as if it was in the car there is a small pad on the lower left hand side where the tranny bolts up there should be a d15 stamped in it with some numbers after it
if it just says d15b its jdm if it says something like d15b7 or d15b1 its usdm
also the pistons have a code stamped in the top of them
take some pictures and we will be able to tell for sure

question.....why would you put a non vtec b7 head on a jdm vtec block....that seems a little pointless....

I think he only has the jdm d15b block and a full d15b7 motor. I'd do it that way so down the road if he finds a deal on a vtec head, he can do a simple mini-me swap and have a strong Sohc instead of the pencil rods in the d15b7.
