I had a 90 hf that had the original d15b6 70hp 40mpg motor. Swapped it for an OBD1 D15b VTEC w/ si trans. New water pump, oil pump, timing belt, DC Headers, AEM Cold Air Intake, Exedy oem clutch w/ stage 3 pressure plate, obd0 to obd1 jumper harness, 2.25 straight pipe with magnaflow exhaust, y8 manifold w/ d15b throttle body and P28 Chipped s100 and dyno tuned. It made 134whp and 106 trq.

I sold the d15b6 longblock, ecu, and trans for $350. And after everything I spent $1,300 - $350 = $950 and I made the same amount of power a stock b16 sir1 motor makes for half the price.

Sold that rex, and now Im trying to do the same thing again!!! Only in a ef can a single came vtec make dohc motors look like jokes.

Haha by the way, if you know anyone thats looking for a d15b6 swap... let me know lol

I had a ls swap with a b16 tranny in my si, pretty quick 15.1 at 90mph and
with a 75 shot 13.9 should be able to do that for under 1500 I did.

Now I have a b18c1 with type r head obd2 with lsd runs 13.8 on motor 13.1
on the bottle, and passes deq.

i just bought an 89 civic dx hatchback 5 speed... and its all stock... im replaceing the head gasket in it and making it run... but i want to save some bread and do a simplistic motor swap... im hearing a B18 will do nicely and is still just as efficeint on gas... the stock d series thats in it gets about 36-40 mph... any ideas????

CPT Del sol

Haha you beat me to it! Its more expensive to go b rather than swapping sohc motors, but B motors has way more potential. If you get a LS, you can LS VTEC later on... Boost or Juice... I was just saying that I got a low miles JDM motor and did a complete tune up on it then made the same power a B16 makes.. D15b motors are lighter but with less potential.

IT ALL DEPENDS ON WHAT YOU ARE LOOKING TO ACCOMPLISH

CPT Del sol

READ ABOVE! GOOD INFO IS COMING OUT

If you get a b18, in order to make it run, you have to go with a b16 trans because if you get the long gears ls trans then it will be super slow.

Simple swap is just putting a d15b or z6 and converting to obd1

I would say go with the D16z6 you will have much more fun with a single cam. When people ask you what you have in your rex you will still proudly be able to say "just a single cam". The z6 engine is the first vtec single cam manufacture by honda and i would recommend this engine over any dual cam. Just bolt on your stock cable tranny and buy a cheap z6 longblock off of craigslist i see them go as low as 150 for the longblock. Also the b18b motor does not have vtec. I have a gsr motor in my crx and i still miss that little single cam that i use to rev. keep it real and swap a single cam you will still be able to spank a b18 crx's. gl

I've ran ls tranny and b16 tranny it's .5 second faster with b16 tranny,
one thing nice is with a ls swap you can plug it all in with no problem
since it's a si. I even ran the d16 ecu when I first did the swap.

(. )( .)

go with the b18

Ass$nyper

Correct.

What always makes me chuckle is all the sohc guys bash the ls trans (as any one should) and forget even an D series Si has longer gears.
If you build your car to impress people, you shouldn't be building cars

D series is better than B series IMO

Displacement is king though, it always has been and always will be. But as far as functionality and reliability, I chose D series all the way.

This coming from someone who has a DOHC Jetta and hasnt owned a honda for months haha.

bluebloodrex

think imma go with the z6. now i just need to find one. would i have to convert it to obd1?

4g4dcruisin

Yes you would.

-obd1 distributor out of del sol vtec or 92-95 civic si.
-Jumper wire harness to go from your obd0 engine harness to match up with obd1 ecu
-p28 ecu out of 92-95 civic si (del sol vtec maybe also)
-I believe your fuel injector resistor box goes bye bye also if im not mistaken.

bluebloodrex

cool thanks for the info

CPT Del sol

Yeah jumper harness, p28, convert to odb1 injector clips, wire up your vtec and distibutor.. Then your good to go
