Question Bout my D15B2

I bought a 88 crx si that had the engine blown so it has a d15b2, my question is why is it that all the d15b2's i see on line
have that black squareish roundish thing but mine has a manifold, is it the same thing is the engine worth doing any thing with cause i beaten lots of cars with my lil crx so it hauls ass, but i had a friend tell me it still had the og si manifold and headers does this mean anything.
second thing any one ever had to change there valve seals? if so how much or how hard is it to do cause mine need to be changed cause its starting to smoke some.wanted to show a picture of what i mean but cant figure out how sorry

yea i wanna kno how much it'd be for someone to change my valve seals - don't really have too much time to do it myself

The engine that was in the thing was a d1616, the best of our generations motors. It had mutli-port fuel injection and was a 1.6L. But the d15b2 was the common motor and had Dual-point fuel injection (meaning two injectors instead of four). Seems to me that when the engine was replaced, someone kept the multi-port and swaped it with the dual-point. Looks like you got you work cut out for you! :thumbsup:

oh i know that the engine was replaced, i just wanna know if there is any diffrence since they left the manifold on the car instead of the dual port

its better the way you have it. both manifolds are bolt on for any d-series engine. since your car was wired for the d16a6, all the did was put in a new block and head, basiclly just treat it as a d16a6 if you need to buy parts.

thx for all the responces and as far as the valves should i just get a new head there only like 75 dollars round here(Houston)

having the head rebuilt is also a good option. IMO, put in a d16a6.

it would be possible to put a d16a6 head on my d15b2 block? if so what would i need to do or what would i need to get besides the head?distiberator?or anything

any one?

Well i wouldn't buy a used head if you can get your original one machined out. unless the heads cracked or something. I have a d15 and i burnt a valve. took the head off and all the valves were sunk in the seats. bought a used head off ebay and put new valves seals on it reused old valves and boy you wanna talk about smoking. the used head apeared to be in better shape but wasnt. i ended up burning another valve. so i took it apart agian. now i have the original head at the machine shop and i bought all new valves and seals and gaskets. it shouldnt smoke at all when im done and i bet my gas mileage goes way up.
cost: $310 for 16 valves
$120 for all new gaskets
$120 for machine work on head
no more smoke out the tail pipe: Priceless

people keep sayin to just put a d16a6 head on my d15b2 block... how and what would i need to do what kinda mods? really need to get my car runnin and back home... can you guys believe some asshole stole my exhaust system the whole damn thing!
