what sup honda tech readers well i want to buy a b16 engine no trans theres alots off b16's with one is faster and got more torque? i know theres years like the 88-91 crx, 92-93 integra, 92-95 civic,99-00 civic, not have much money for the type r so that one is out off the list the motor is going into 89 rex with ls trans any advice will help thanks

 

Translation:
Better.

To answer your question, a longblock choice within the B16 family will not determine how fast you go. It will give you a baseline on how much power you should expect, which won't be that much of a range, but your transmission will determine fast in both the acceleration and top-end definitions of "fast." Currently your choice of the LS spec. transmission is poorly suited for the B16 motor.

 

found this site when i was looking for info about my B16b...a lot of good info on this site...not sure if it helps mostly b/c it's JDM and EDM motors

Bore, yes. Stroke, yes

Edit - Pointed out to me that I was incorrect on stroke.

 

What would you suggest as a good transmission (money aside) for this swap?

 

B16 tranny, cable? If you car is still cable.
One could be had for anywhere from $350 to $500.

There is a company out there, I think it's bisimoto that makes B2D adapters.

Waste of $. That adapter would cost $1000 + d trans with shitty gearing.

Just find yourself a cable S1(b16 version not ls), J1, Y1 or YS1 gsr.

 

B16b and b16a have the same stroke but the b16b has longer rods b/c of taller block.

 

I stand corrected, I remembered the taller block but failed on the rod length.

 

so i losing alot power with a ls trans? if i get any b16?

 

not losing power...just not harnessing it...i have an LS transmission with my B16b and always drop out of vtec when i shift...but it's not often i'm in vtec and love this transmisson b/c i'm mostly on the highway

 

Ls trans suck on everything, even ls's. B16's lack of torque at low rpm requires the shorter gearing of a b16 trans. Trust me, you will hate an ls trans on a b16.

 

i don't hate mine...but then again i don't drive fast everywhere and i don't always engage vtec...

 

I don't "drive fast everywhere" either. Physics is physics. Honda designed the gear ratios they did for a reason. Have you driven your b16 with the right trans?

 

nope...everyone says it's night and day...but since my transmission is good then i'm not going to change it...

but to the OP...you should change your transmission to the correct one in order to get the most out of your engine...but if your strapped for cash, keep the LS

 

that tranny sounds like the shizznit for a highway car. ill trade you my b16 tranny if you want bro. lmk.

 

nothing like crusing at 80mph and being at 3600rpm

 

3600 rpm! wow, I bet you lose some speed going up hills at those revs....However, with lower revs come some advantages too. I bet you're getting about 40mpg on that b16b correct?

 

not too many hills where i am so it's not that big of a problem...the highest mpg i got was 33, mabey could have gotten more, but i don't like getting close E...but it's weird though, when i had the B18a1 in my car i was over 4k rpm and now i'm under...and i was wrong saying 3600, more like 3800

i'd considered getting a B16 or GSR transmisson and puttin in an LS final drive, but that's $$$ i don't have

 

My stock b16 with an S1 trans got 30mpg regularly and a little more if I really tried, so not much worse @ 4500rpm. My cammed b16 still gets close to ~28mpg average.

 

well guys is alot talking here thats great for me .. i not street racers i use my car for work every and here in alabama are alot off hills i driving my rex with d15b 89 hf trans i ****ing hate long gears on the hill sometimes i have to drop it to first gear for a hill .. with b16 trans is the shortes one? j1,sy1 ? and you think b16a2 is the best swap for a 89 crx hf?

 

To answer to OP's original question:

1st gen B16A- 160hp
10.2:1 compression

2nd gen B16A- 170hp
10.4:1 compression with p30 pistons
- better cams
- better intake manifold

Really, thats the most part of the differences between the two generations.

As far as the tranny is concerned, and LS tranny is "not" the choice for a b16. If so, the low torque engine will perform sluggish and will fall out of vtec every single time you shift due to the gearing.

Another choice often overlooked that will out perform a B16A is the later B20Z. It makes crazy useable torque, and roughly about the same hp.....it is an under rated spec from factory. Also works great with an LS tranny and ecu. I run one in my EK civic....its awesome!

 

so i think i going with b16a2 i try b20b but i got stock with parts so i sold it i want to order a complete changer over from honda motors b16 will kill a ls vtec ?

 

i have no idea what you're trying to say

 

i said a b16 will rape a lsvtec?
