just looking for a decent engine to put in my 91 crx si. found one with 86k on it out of a 90 dx. so it is the 1.5L. will hooking up the mpfi intake and droping it in my 91 si give it any more power or will it still be the wapping 68 horses that comes stock in the dx. any info would be great. thanks guys

 

Stock '90 D15B2 is 92hp. Stock '91 D16A6 is 108hp. An MPFI D15 would be somewhere in between.

 

sounds ok to me, i just want to be able to make it up hills without dropping it down to 2nd gear

 

stock D15B1 from Civic STD is only 70hp

yeah that is the one i was originaly talking about. so d15 b1 has 70 hp, and the d15b2 has 92hp?

A D15B1/2 with MPFI will be almost equivalent to a D15B7 in terms of power.

 

Do a Vtec d15 or a ZC. I think you'll be much happier.

More Power!!!!

 

hahaha yeah i am not looking for a racer out of this one, i have my other crx for that, this one i just need to be reliable, so i need opinions i have a chance to buy a d15b2 with tranny and 86k original miles for $350 is it worth it or should i keep looking for a cheaper d15 or d16 i dont really need the tranny, but he will not seporate and i guess i coule always use another good 5 speed dseries tranny sitting around, what do you guys think?

 

Do the mpfi swap, it will help alot, but a crx si cam or sohc non vtec zc cam is the icing on the cake. A shorter geared Si tranny will help to.

 

yeah iwill always have the si cam from the d16 that i pull out maybe after i put a few miles on her with the d15b2 i can do an over haul on it and swap the si cams in

 

Si cam, Si intake manifold, 92-95 Si exhaust manifold (stock) and you will free up a good ammount of power, enough for you to not downshift, and all the parts are relatively cheap! Having a short geared Si tranny will help out too.

 

yeah i will have everything with the exception of the 92-95 exhaust manifold, i never knew they where different, are the larger? or what is the difference?

 

i was wondering the same thing about the headers...i hear ppl say that all the time????

 

i also heard somthing one time about people putting a b20 intake manifold on the 92-95 dseries engines but i never really looked into it

One it wont clear the hood and two it wont bolt on.

just said i heard something about it, hoods can be modified and the b20 has been around for a long time so it could have been an intake manifold off of the older b20

think those exhaust manifolds are factory headers. 4-2-1 or just 4-1 i dont know .. i also could be wrong.. i know b18s had the factory headers.

anyone can correct me if im wrong cuz i know i am.

It would stick so far out of the hood you would need a very very impressive cowl. This is why everyone running a B20 in anything NOT a CRV uses the B18B intake. Also, do you also fail to realize we are talking about a D-Series motor so no B-Series intakes will fit.<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by ludesrv &raquo;</TD></TR><TR><TD CLASS="quote">92-95 Si exhaust manifold (stock) </TD></TR></TABLE> I thought that the exhaust manifolds didn't come 4-2-1 until the D16Y8.

i believe you are refering to just the throttle body replacement

and all d-series stock exhaust manifolds are 4-2-1

 

no 88-91 Im very sure is 4-1, I just removed mine recently and put the well priced megan header on


my setup:
d15b2, mpfi swap, si cam, si trans.
pulls pretty good especialy in comparison to dpfi!
the d16z6 IM flows much better tho and I may upgrade to that...

Which battery is that?

Also. the z6 had a 4-2-1 header(which is what i have now), a6 and dx/hf (crx) had 4-1. the y8 had a 4-2-1 also.
