D15B1 vs. D15B2...

Hey guys...
I have a good B1 in my smashed STD that is one of the best engines I've ever seen...and a "dying" B2 in my Si that I am driving...I'm contemplating pulling the B2 out of the Si and putting the B1 in...leaving the Si distributor and the Si MPFI...I only have $1000.00 to work with, and pulling an engine is wayyyy beyond me...so buying another engine is outta reach...
I guess what I am asking, is what am I really sacrificing here?
I've been told that a d15 with the Si distributor and the Si MPFI can actually end up making more HP than the stock A6...is there any truth to that?
:confused:

I'd actually be interested in knowing the answer to this too - i take it since you have a STD like me, the D15B1 is the wimpy 70-ish HP1.5L engine?
so what exactly would it take to beef it up a bit, to at least be more like the 100-ish HP 1.5L engine? I have no idea what the differences are.

swap the block.
use the A6 head, or atleast the A6 cam, and you will basically have a "d15a6"

The thing that makes the b1 and b2 different are fuel maps in the ecu and the intake manifolds. I think thats it but i'm not sure.

the B2 and B1 have the same intake manifold, although the B1 has a restrictor plate and a half opening choke to limit power. the ECU is different as well as the cam (or so i've heard).
the blocks are essential identical, so using a d15b1 block with a d16a6 head/cam/intake will basically give you a d15b7, or around 105hp.

interesting
i just did a valve job on my b1, so i'd like to stick with the head, but it sounds like a relatively easy/cheap way to get a little more oomph would be to swap the intake manifold from a junkyard engine
so i guess i might as well go straight to a SI manifold (rather than a dx) and do the MPFI conversion? I would expect that since the mpfi is supposed to help the dx a bit, it'd REALLY help a wimpy std.

swaping a motor is not as hard as it sounds. if you take your time and have everything ready you could start on a saturday and have it running by sunday.
the right tools will make or break you on this... when I put my B16 in the hardest part was getting the axles out without an impact wrench... IE: impossible ! so I broke one :icon16:.
hehe

It is if you've never done it...wanna come help do mine ;) There's a case of beer in it for yah ;) heh.
Hey Kun, see what an A6 goes for down in your area of the province...It would be nice if I could get the Si at least back to stock...sigh.

Would a B16A2/3 slip into my engine bay with minimal problems?
What about a D16Z6? as a second choice?
Just curious...thanks

If you search there are many posts about those same motors into a 4th gen.

look in the faq at the top of the list
i really think the way to go is a y8 - newer engine, but still a bolt in
the z6 is similar but a bit older, any B series is gonna require a mount kit (more money)

A6's are pretty rare around here too... I can keep an eye out for one... I do Have one in peices in my garage... but i'm gonna need some peices of it to (hopefully) Fix the Civic. if not I'll have two and probably a D15B in the civic.
As for helping for the swap I'll see what I can spare for time... the downside is I don't drink :nono:

I was only kidding about the help...but if you would be willling that's be cool...oh and you don't drink?!?! wow, that's rare...probablyu better when working on engines ;)

What do you mean you "wouldn't mess with the D15's" ??? I don't understand what you mean?
Also are you saying get the "a6" block and use it with the current engine? or get an A6 engine complete?
*sorry for the dumb question's...I'm new to the whole engine thing*
