B18A swap

[IALuder]

ok heres what I know so far.....

You need motor mounts (azracemachine.com)
rear mount bracket from b16 civic (junkyard or hasport.com)
engine harness from the b18, don't use the civic one.
use a obd1 ecu from a 93 non-vtec integra
cable conversion kit for the tranny (hasport.com or be creative and make your own)
93 integra shift linkage, or cut and reweld yours to fit
and probably a few other little things


ARD Performance.com has alot of the items that i will need for the swap, Half shafts, ECU, Wiring Harnesses, Long Block, Head, Intake and Exaust Manifold.

What can i fit on the B18A block... The answer is ANY 'B' series
Head. If im going to use a turbo i can decrease the compression ratio to about 8.5:1 so i can use more boost so that the extra compression will not damage my head.
And by doing so you can use 7lbs of boost to 9lbs without any problems... (B18A has 10.5:1 or so) But If im not going to change the compression (leaving it stock) build up the bottom end of the ie. forged pistons, racing crank, forged titanium
conecting rods, Stage 3 clutch and 9lb flyheel. Now for the head; forged rods, rings, cams. That is only if im not going to change the compression.

Now for the Bottle, Port polish and shave the head, high dome pistons (increasing the compression

am i missing anything? and has anyone else done this?

Im a n00bie to the swapping of motors.

thanks ben

youre completely all over the place....decide what you want to do first (NA/Boost/N2O)

Youre like "Im gonna raise comp. for this, lower if for this, raise it again for this"

Turbo and NA apps use different n2o setups, wet or dry...so that is somehting that you'll need to figure out as well.

Is this your daily car or just a fun-mobile? From the sounds of it its a fun mobile...

[IALuder]

its a fun-mobile for right now. I drive a 1988 All-Trac Celica for my daily car.

well I want to know, which would be better Turbo or Supercharger on a 1993 Teg LS motor?
Greddy Turbo or Vortec Supercharger.

then I will know which n2o set up to use.

after the swap, the Vic/Teg will become my daily car.
goodbye All-Trac.

[MAXed Out]

I own a 92 teg Ls my self i dunno too much about engine swaps but if i were u i would get the Vortec Supercharger.

[pdiggitydogg]

boost via turbo imo

[AzCivic]

go turbo!

and if you wanna run both the turbo and nitrous you're going to have to replace the internals(pistons/rods) for stronger aftermarket ones.

[IALuder]

thanks guys for the input.

i think ill do a B18A turbo with n2o.

now for better pistons...which would you prefer? spoon

ben

[AzCivic]

SRP/JE, wiseco or arias.

"there is no spoon" especially when talking forced induction.

[IALuder]

really i never knew that. dang i need to read more about that stuff.

but in opinion would this swap be a good idea?

B18a LS in for a D15b DX

[AzCivic]

yeah its a pretty good swap, its not too expensive and will make good low end power(relatively speaking). i'd put the engine on an engine stand and replace the pistons/rods myself, then swap and then when funds are available boost it like crazy. 300hp or more should be pretty easy with the right turbo/ fuel setup. so you really don't need nitrous.

isnt the LS a B18B??

[IALuder]

a B18B is for 94-00 LS/GS Tegs
B18A1 or B18a is 1992-1993 LS/GS/RS Tegs

the difference between the two is amount of hp (2) and lbs of toqure (1). bore and stroke are the same. both 1.8L. both non V-tech. Plus a B18B swap coast more then a B18a. why becuase B18a can use civic stock parts. Suchs as injectors fuel oil pumps/lines and shift linkages, guages. the basic stuff. alls i need to buy to do this swap is Mounts, and Engine/Tranny. Ill upgrade the fuel and oil pump when doing the swap just so i dont have to do it later on. save me some time and waste more money.

Ben

The difference between the two is obd I vs obd II.

Also b18b's are hydrolic clutch and a's are cable...

The oil pump is in the engine... so the proper one is already in the block you swap in.

I don't think you need mounts... just the rear bracket... all the others should swap in fine...

[IALuder]

well i have talk to lots of people who have done a b18a or B18B swap and they suggeested doing mounts. plus sence im not swap auto to 5spd the hydro and cable links dont come into the picture.

Plus it looks like all my funds are going into fixing my semi/very little damaged civic. read the thread hit and run.

ben

[nonovurbizniz]

I don't think a b-series auto tranny fits in a civic...

Not positive but I'm pretty sure.

[IALuder]

well people do b16a swap to the civics and they do b18B and b18c. so it must fit with some adjusting. i was told it was possible with the right amount of cash.

ben

[Shaved &/or Laid]

with the 'right amount of cash' you can ditch that flaming auto and go with a non homo-erotic 5 speed.

[IALuder]

why you gotta hate.

[nonovurbizniz]

People swap ANY b-series ENGINE into a civic... it's the b-series auto's that don't fit...

Again I'm not positive but I'm pretty sure... NO b auto will fit in the civic...

I'll look into it...

Maybe I'm wrong.. maybe it was the h22 that wouldn't fit the auto in a civic... cuz now that I think about it I think you could get a civic in japan with dohc auto...

[pdiggitydogg]

^i know you can get an auto b16 in japan

[Shaved &/or Laid]

Not hating, just telling the truth.

a) honda automatic transmissions are EXTREMELY ass for racing. Period. They are slow. End of discussion

b) you want to do all that work just for a transmission thats EXTREMELY ass and theres no reason to keep it at all.

c) you want to have racing props ? nobody respects a guy who cant drive stick. If youre not good at stick, youre not good at racing...or drivign for that matter. Anyone can push a damn pedal down and hold it.

Disclaimer: also, dont give me shit about beign a 'hater' cause 'im jealous of you doing a swap'...that seems to be the trend nowadays.

[IALuder]

aight calm down.

Im pretty sure you can so a b series auto swap. i have seen a auto b18b in a civic. it was a show car.

now on to shaved

A) i can drive a stick. my daily drivin car is a 1989 celica stick shift all trac. more powerfull then any civic and accord.

B) i cant pimp out a 89 celica becuase companys think its to old and nobody drives one to make parts for it. its to expensive to do custom making of anything now a days. so i just drive it as a daily car.

C) My civic was cheap. so getting it for the amount that i did i figured doing a engine swap with a auto tranny will make up the extra money i would have to spend on a higher price and nicer shaped civic on the year.

D)in the future after paying everything off and the swap to a bigger engine is done. i will buy a Stick shift for the civic.

E)when i go to the junk/salvage yard maybe theyll have a whole acura 5spd i can take and do it all at once. i got 1800 to spend on swap. i may go bigger to B18B.

[Shaved &/or Laid]

okay. i have a deep dark hatred for AT transmissions.

[IALuder]

its coo. i understand.

i am swapping to manual but with limited funds itll take me longer. i cant do it all at once.

till then, im looking for a tach to put in my car.

ben

Hey, noooooo No2 too much pressure on the engine unless u got a another to put back in after u Nos and turbo that engine, trust me it will blow

[IALuder]

huh, what?

im not dumb i know how much pressure to put on a engine. plus NoS is not going in my car for a long time.

Plus i decided that in a couple of years, after college and sh1t. i will buy a B18c5 and mod/boost that mutha up. i blew my DX engine a week ago it seems like. i will buy a 92 civic Vtec engine, till the cars paid off and i got more funds. i may take a loan. buy the B18c5. be better then those who do B20 and B18b swap. the most pointless swaps there are.

[pdiggitydogg]

dude...you dont have a clue about swaps...total honesty

for the money, the b18b is the best swap for boost that there is.
its already low comp so its great for boost, inexpensive, nonvtec so there is less strain on the motor at all times. Go visit honda-tech and say that...you will be banned within minutes...if not owned entirely. for the price of ls and custom turbo you could spend under 3k and beat a shit load of cars including c5's.

b20 is a very torque-y motor and great if you just want that. Ive done research on them recently, and tue, they do appear not to last long after crvtec as a daily driver, but they are a great nonvtec boost motor, or great for race. A simple b20 bottom and a type r/ported b16 head and you "should" be able to run mid to low 13's with the right tuning...sounds like a type r motor to me.

so think and do some research before you talk shit about the underdogs/hidden treasure b's

non-vtec power
I give props to the swapped b18b's and the b20's

What about us trendy b16a owners?

c'mon pdiggs, where's our props - j/k

Ya, the b18b is great for boost cause it has low comp and long gear ratios - it also requires very little tuning since it has no vtec.

[pdiggitydogg]

oh sorry...MAD PROPS TO THE B16A'S!! "TIGHT Y0!"
something like that?


b16's are the torqueless wonder...I do have love for them

coo

hey Pdiggs, you think that the Greddy turbo kit for a 99-00 civic SI will work with my car - everything should bolt up fine, im just worried since the kit is designed for an OBD2 car and my car is OBD 1.

[pdiggitydogg]

it'll work fine...just dont use the blue box
run the afc hack or similar

other than that...perfectly compatable (Ive looked into it)
it will also work on the b16 powered sols (a2 and a3)

please explain how longer gear ratios are better for boost on a 4cylinder engine?

Because you can ride the added power for a longer ammount of time. - thats why turbo cars have long gear ratios and NA cars have short gear ratios.

there is no reason to have short gear ratios on a turbo car since your power band is so wide, not narrow like a NA vtec motor.
i.e. longer gear ratios take advantage of the added power and torque from the turbo kit - boost increases linearly, so its stupid to gear the car with short ratios, the more you shift, the more power you miss out on with the turbo.

i guess what im trying to say is the more you shift the more you loose spool, and, since boost increases linearly, long gear ratios will allow the car to use more power.

-the powerband on a turbo'd 4cylinder in anything but wide.

-boost increases with exhaust out put, if you're sitting at 3k rpms and someone with shorter gears is sitting at 3.5k rpms and the setups/throttle position are the same the guy with the shorter gearing is making more power, and is faster.

-longer gearing being great for turbo is a myth.

ok - take 2 b18b powered (BOOSTED) Civic eg hatches, both weighing the same, with the same exact mods: identical cars with identicle drivers. the only difference is one car is using stock ls gear ratios and the other is using shorter ones. Guess who gets owned, the moron who decided to use the shorter gear ratios - robbing his car of potential power from the turbo.

Tis no myth

[AzCivic]

you just made an example and came up with your own out come based on opinion.

both cars make the same amount of power, one gets to the thick of his power band quicker, the other one lags behind.

No, they dont make the same power.

The car with the longer gearing makes more power because its turbo will spool longer thus making more power than the car with the shorter gearing.

[AzCivic]

gearing has nothing to do with horsepower output, pure and simple.

Duhh, but PROPER gearing allows you to use your setup to the full potential.

If gearing has nothing to do with power output, then why on earth do people change their gear ratios to suit their setup? - "oh wait, cause they are able to get more power from their setup (or in the case of NA cars, getting the power quicker)"

[AzCivic]

so you only want to get the power quicker in a n/a car but not a turbo one??
