ya pretty much everything

the only car that you can drop that ls in and have it fit perfectly is a 90-91 Integra

Bseries in a 84-87 is a huge pain in the ***

1st gen crx = 1st gen integra motor
2nd gen crx = 2nd gen integra motor
you should sell me the ls motor though

But it's definitely not impossible. And it is certainly worthwhile. It is true that the motor will not drop right in. But Hasport does make a mount kit that will allow you to drop it right in. And I believe they also make axles. Just keep a couple of things in mind. First of all, this stuff from Hasport is not going to be cheap. The mount kit, for instance, costs well over $500. If anything is going to be a deal killer, this is likely to be it. Also, if the CRX is a carbed model, significant fuel system and electrical system upgrades will be necessary to run the stock fuel injection. Of course, if you are willing and able to deal with these issues, the swap should be VERY rewarding. 1G CRXs (especially HF models) are extremely light. If anything, this is reason enough to do the swap, as it would make that car FLY.

If the 87 CRX is an SI with MPFI then its a difficult swap but well worth it. If the CRX is a carb motor, then don't even think about a swap like this. You would have to change the entire fuel system(including tank and all lines) and alot of the wiring, a real PIA.

On the other hand, a 1G HF weighs ~1700 pounds. Just imagine what that car could do with a swap. But a 1G SI actually weighs more than a 1988 HF, 1988 DX, or 1989 HF. And all of those cars are easier to swap.

actualy you dont have to swap the entire fuel system if its a carb car, you need to add the Si fuel pickup to the tank, Si fuel pump and the Si return line possibly(some people have had too, some havent)

but you still have to add Electronic advacne no matter what car it is, theres a fair amount of wiring involved, and swap parts are extremely expensive, as i well know, i ordered my mounts last week, i have a 87 Civic Si, mounts are $570 without a discount, axles either come from 2 places and are about $350, the rest is cheep compared to that, but its not the eazyest thing in the world, im shure its eazyer to put a Kseries in a EF than it is a Bseries in a EA

NOT EVEN CLOSE!!!

Dropping a B-series into a 1984-1987 is MUCH easier than dropping a K-series into a 1988-1991. First and foremost, you must NOT forget that dropping a K-series into a 1988-1991 is NOT a drop-in affair. Even if you use Hasport mounts, there is no way to get away from the fact that cutting and welding is required. Then there are shifter cables to contend with. Adding shifter cables is a MUCH more difficult task than simply changing the length of the linkage. And then there is wiring. Wiring an OBD2B ECU into a 1988-1991 is going to be AT LEAST as hard as wiring up a 1988-1995 ECU into a 1G CRX. I don't know about you. But I would MUCH rather be faced with the task of dropping a B-series into a 1G than dropping a K-series into a 2G. Even if the 1G is carbed.

Don't remember where I got this but credit is within.

HTH,

Donnie

Answer: Swaps for the 1Gen are a little trickier.

In any case, having the car be a Si to start with is a BIG PLUS
because you already have a car designed for fuel injection. The 84-
87 DX + others were carbureted.

If you do not have fuel injection already you need to:
1. Swap in the fuel injection system from a car that has it (pain)
2. Convert your new engine from fuel injection to carburetion (pain)

Ok so once we are past that point, what fits?

There are basically 3 classes of swaps.

1. Engines that bolt in.
-D15A? = stock 84-87 Si motor. Light, 1.5L, no power, no torque, no
point.

-D16A1 = Stock 86-87 Integra Engine. 1.6L 125HP, ? torque, not a bad
choice, particularly for forced induction due to relatively low
compression ratios and easy availability via junkyards. Needs axles
+ hubs from an integra too. Can use stock wiring + ecu, although not
recommended. IMHO easiest swap. See hybrid.honda-perf.org for help
with this one.

-D16A1 (2) = Stock 88-89 Integra Engine. 1.6L 130HP, ? torque, not a
bad choice either. I break this off from the above because it is
basically the same engine with marginally higher compression ratios
and DIFFERENT WIRING. Marginally more of a pain but still pretty
simple.

-BROWN VALVE COVER ZC- all the engine import shops can get their paws
on TWO ZCs. The black valve cover ZC is NOT THE ONE YOU WANT FOR
1Gen!!! USE BROWN VALVE COVER FOR 1GEN!!! The brown valve cover ZC
is basically a JDM equivalent of the USDM D16A1. Everything above
about D16A1s apply here. nippon-motors.com told me $495 for the
engine, no tranny or ECU. I got my tranny from a junked 'teg.

2. With an engine mount kit, serious amount of wiring, a new ECU you
can have:
-B16A1- 160HP, ?torque, Vtec, a nice choice period. JDM Civic SiR
engine. Fairly lightweight compared to stock engine. Easily
available from JDM engine importers, ~$500 for engine only, ~$900
engine/tranny/ecu, optional LSD tranny available for $250-500 extra.
With Hasport or Place Racing mounts, this thing will bolt up. It is
a much more involved swap then the D16/ZC, but you get a lot more
motor. Hasport can help with custom wiring harnesses if you aren't
feelin adventurous. Be prepared to spend more than the engine cost
you on mounts, axles, intermediate shafts, hub/knuckle assemblies,
and custom wiring harnesses. Even if you get junkyard parts, this is
still an expensive swap.

-B18B/B1-?HP, gobs of torque, non-vtec, decent amount of cash. Some
people report clearance problems necessitating a custom hood. Nice
engine for forced induction. Everything above about axles, etc
applies here. Wiring can be tricky.

-B17- ?HP, ?torque, cheap and rare B18C1 ish VTEC 1.7L engine. Nice
choice for people looking to get B18 torque w/o B18C prices. Wiring
easier compared to B18C1 + B18C5

-B18C1-170HP, 128ftlbs of torque. Integra GSR engine, 1.8L, Vtec,
Nice all round engine. Lacks the compression ratio and SERIOUS
performance internals of a B18C5, but normally can be had for several
thousand less. Think 2-3.5Grand for engine/tranny/ECU. Think hard
about wiring because this car needs a OBDI or OBII ECU, which is a
lot different from the wiring in a 1Gen.

-B18C5- ~200HP, gobs of torque. Integra Type R engine, 1.8L Vtec,
built to be driven. SERIOUS engine. SERIOUS price. Think $5000+
for JDM ITR engine/tranny/ECU. Serious wiring headache as above. If
you wanna be super cool, then this is the engine for you. BE
WARNED! I think hasport says the ITR tranny is incompatible with
their mount kit. Your mileage may vary, but if you are even
considering this swap you probably have enough money to burn you are
a sick lunatic.

-B20 / B20Vtec - ?HP, More torque than any other NA honda engine.
2.0L non-vtec. With a head swap, you have Vtec and a very powerful
engine. You can bolt B20s in to a 1G with the hasport mounts, and
the ehad swap is well documented elsewhere. REMEMBER, THE STOCK
HEAD/INTAKE MANIFOLD WILL HAVE CLEARANCE PROBLEMS!!! expect to pay
about $1000 for a stock B20. Wiring probably will be somewhat of a
headache due to how new most of these engines are, but I haven't
really investigated this swap for the 1G (although I'm doing it for
my 2G rex)

3. You are insane and you can custom-fabricate mounts.

-H23 - one word. Why?

-H23/H22 head swap - two words: You're nuts!

-H22 - Well, if you don't feel like being able to steer the car due
to weight problems but you just have to have 2.2L of displacement and
torque, be my guest. I've seen pics of H22s stuffed into a 1G but
that really sounds scary to me. Good luck on the wiring too!

-Exotics. If you have money to burn, light it on fire. When you are
done, post pictures of how you stuffed a Chevy 502 into the engine
bay by welding a cage to the front end of your car.


Hope that helped a bit.

As for recommendations, I'd get a 86-87 Brown vavle cover for
simplicity or a tight budget for sure.
If you have a little more time, energy and patience, get some B-
series mounts. For forced induction, I'd definately get a B18A or
B20 (remember, you cannot run the stock B20 intake due to clearance
issues). For NA, I'd get a B16A1 with a LSD and do hella performance
upgrades before I got the B18C5 or even B18C3.


Here are some links that will help you much in your decisions:

-Engine specs thanks to hybrid
http://hybrid.honda-perf.org/tech/engine.html

-1Gen Swaps with B series engines thanks to hasport
http://www.hasport.com/85-87si...e.htm

-Nippon motors who consistently have brown valve cover ZC engines for
$495 http://www.nippon-motors.com

-Honda Motors online has brown valve cover ZC engines
and has REALLY good prices on B16s http://www.hondamotorsonline.com


Hope that helps.
peace
