Well motor is finally giving up close to 200,000 miles its about time things start going wrong. Thats what i get for jumping into buying something with 196,000 or so miles. With a blown head gasket and pretty sure my timing belt broke this morning. To fix these problems on my d16z6 im probably looking at the same amount of money or maybe even more then to buy the JDM D15B which from what i know is the same as the D16z6. So I need some input on what to do. If I buy my new motor I think that I'm gonna go through (Hmotorsonline) as i've seen that be recomended alot on here. Anyone ever drop in a motor from them and have any problems?

 

any input appreciated thanx!

 

bump for input

 

its the same, just a little smaller in displacement.

 

thanx. im really thinking to just swap it out. I don't think its worth the hassle of trying to fix my old D16z6

 

bump!

 

everything i read says the 15b will be faster than the z6, specs all look the same though

 

i've gotten several from hmotorsonline. all legit. they recommend that you change water pump, cap, rotor, plug wires, oil pump (i think), timing belt to keep warranty. all of which you are probably gonna have to do with yours... may turn out to be a little more $... but at least you get a motor with lower miles...

 

The Jdm will be better if you plan on turboing it, Other than that.. there pretty much the same.

 

well i was hoping to just drop it in and be cool but ill check it out i guess when i get it see what needs to be done.
how many miles do there motors average? in miles or km whatever? i know they come in km.

 

it'll drop rite in, u can use the p28 ECU also, just change the timing belt

 

i know the motor should drop in. what do those motors average? 30,000miles?

 

You 100% pulled that statement straight out of your *** or you've been grossly misinformed.

The D15B Vtec has a compression ratio or 9.6:1 vs the D16Z6s 9.2:1, now I'm certainly not a forced induction expert, as a matter of fact i'm far from it. But I can tell you that no one who knows anything about turboing will tell you that its better to use a higher compression engine for boost. Thats not to say people can't and haven't turboed higher compression engines, its just not as easy to do reliably.

For the record, the D15B Vtec isn't just a JDM version of the D16Z6, it can probably be best described as a hodge podge of D-series parts:
-D15Z1 (VX) block
-D16Z6 rods (EX/Si)
-D16Z6 head (EX/Si)
-Unique D15B Vtec cam, slightly more agressive the the D16Z6
-Unique domed pistons
-Unique D15B Vtec crankshaft, rod journals are the same as a D16Z6, the main journals however are the same as a D15B7
-D15Z1 (VX) water pump and timing belt, tensioner is not available in the US, the D16Z6 is the closest thing available, it has a slightly larger diameter roller.

 

I think more in the 50,000 mile range. Still very low mileage for an engine thats 15 years old if you ask me.

 

thanks i was wondering what was the difference between them.

 

Do you think HMO will know the mileage? Ever bought from HMO?

 

I doubt it, they'll probably just give you an estimate or an average. And no, but i've only heard great things about them. I bought my own D15B Vtec from a company called sunrise JDM motors in montreal and had no problems with them, i'm just hesitant to recommend them because I don't know of a single other person who's bought anything from them.

 

well its gonna be a hella lot better my 200k+ d16. an i can tell my motors previous owners beat the Sh*t out of it. I got it and tried to take care of it right way but i guess it was just its time.
at least now i'll have some what of a fresh start.

 

I think the D15B is faster from my experience.

 

i think like 5hp more WOOT! lol
kinda excited somewhat new start just gotta make sure i do this right.
Anything i have to convert? Or is it basically drop it in plug-n-play?

 

It just drops in. If I were you i'd replace the timing belt, water pump and thermostat before you drop it in.

 

Sounds good to me an extra $100 on something I won't have to worry about later.
I have the thermostat from the last one which I replaced in like august. But its probably a better idea just to get a new one. Oem or Autozone last time i bought that failsafe one supposibly if it goes bad it stays open.

 

so whats the best book out there? Or is there a good DIY on here to help me with this swap From Dseries to another D series.

 

bump

 

i did my remove and reinstall myself its not hard to figure out all of the stuff is fairly easy but if you want a good service manaul ive heard good things about helms manauls id buy one myself just dont have the cash right now lol
