engine swap

Is it possible or rather is it easy to swap a B18C5 engine into my 1990 Honda Civic DX. If it can be done is it more or less take the old one out and drop the new one in, or is there alot of remounting to be done. If it cant be done with the Integra Engine then does anyone Know an Engine that would swap easily?

Well if you gonna get the type R motor then go for it! Since you have a DX you need to convert dpfi to mpfi.

Go here for more info....www.hasport.com

You will need mounts/shift linkage/cable to hydro tranny conversion kit and if you like you can buy the dpfi to mpfi wiring harness from them. You will also need to get axles with intermediate shaft from them. Everything is all there. Also you will have to convert obd0 to obd2 which isn't that hard but do some research and hopefully you can get an idea. B18c5 is a good choice but it is expensive. But you dont see that many 4th gens with b18c5 in it thats for sure :)

first of all thanks for the help but what does dpfi, mpfi, obd0 and, obd2 mean? I am very new to even thinking of doing an engine swap so I dont know much of anything. As for the shift linkage and axles can those be taken from the integra or are those a specialty type part? Where can I get the cable to hydro tranny kit? Again thanks for the help.

im not sure if this is what he's talking about but:
dpfi-direct port fuel injection
mpfi-multi-port fuel injection
pretty much dpfi has one injector feeding the whole engine whereas mpfi has however many cylinder (sometimes for for F/I).
As for the different obd's they are just a system of sensors working with you ecu that check on different emission things. ie: Throttle Postion Sensor (tps), O2 sensor, intake temperature sensor.....
i hope thats right and helpful

Good JOB :thumbsup:

Look, if you dont feel comfortable doin it yourself then take it the shop. Expect to pay 5500 with labor.

Thanks I wish I knew as much as the people posting o in this forum! I'll probably have some of my friends help me do it since they actually know alot about mechanics, cuz 5500 is very expensive but then again so is the engine. About the axles and linkage though can they be used from the integra or do they need to be bought new?

Just buy the axles from hasport along with the linkage. They'll tell you whats the best set up on the axles. :)

Instead of getting a cable to hydro tranny kit would it be possible to just take the whole clutch out of an integra and put it in my car?

No because cable and hydro trannies have differen't clutch set ups. Just grab the conversion kit. Believe me you'll love the type r trans!

Im seeing everywhere that trying to turbo the B18C5 is very very expensive so I was wondering if there is an engine that I can put into my civic and be able to turbo well for under $5K? Me and a friend are tryin to do an engine swap but he's going v6 on a totaly diff car so as it is his car will be faster.

try putting in a h23 block wit a h22 head and turbo it....its been done on a CRX and the damn thing is a beast...

but your still gonna need all the other changes as well but this change would most likely be cheaper than the B18c5.. (correct me if im wrong)

good luck

Way too much work! Not worth it. If you want to turbo a b18c5 then you have to find a GOOD TUNER since the motor is high compression. I just got done with a heated discussion about this. Some ppl say "oh its not safe" when they dont know what they're talkin about. Many ppl have done this. Look around at www.honda-tech.com. I think theres quite a few ppl runnin this set up. You'll be just as fast or fast on low boost then with someone boosting high on a built motor. Its gonna cost you way over 5g's though. The motor itself cost about 4200 and the turbo kit cost about 2500-4000 depending what kit. You can get it customed if you want. Me bein lazy and all i would just buy the kit. Ditch the fmu and get yourself hondata and TUNE! If you want to go cheaper then get the LS motor which you can find anywhere between 700-1500.

Believe me its not gonna take much to beat a v6 or v8 :)

Instead of the B18C5 I'm gonna do the B16A. If I get the swap kit from http://hmotorsonline.com from an 88-91 SIR1 will I be able to just"drop" it in(after I get new mounts of course), Or will I need to get new wiring, shift linkage, and axles too? What is the diff. between the LSD tranny and the other ones? What about the B16 from the 92-93 Integra XSi, would that be the same in terms of parts needed for the swap or will it need more/less parts. What swap would be easiest to do and mod later on? Thank you so much in advance!

if you want to turbo get a ls, they can handle about 10psi stock.

B16a is a good choice. I can understand you dont want to spend too much money :) Anyways ...any b-series motor you WILL NEED the following...

Aftermarket mounts ( either Hasport or HCP which are the 2 best and my favorite)

90-93 integra axles along with the SAME YEAR intermediate shaft
You will need to convert DPFI to MPFI. If you're lazy to convert it, just buy the harness from www.hasport.com

You will need a aftermarket shiftlinkage from Hasport.

You also need to wire up the vtec. I'd have the shop do the swap unless you know someone good enough to do this for you. You're lookin to spend about close to 2g's without installation.

What is the diff. between the LSD tranny and the other ones?



LSD means Limited Slip Differential. I'll explain it in simple terms. Its much better to have LSD because it'll grip the ground much better because both wheel spins instead of one. Do some research on LSD. You'll find plenty of infos on them.

What about the B16 from the 92-93 Integra XSi, would that be the same in terms of parts needed for the swap or will it need more/less parts. What swap would be easiest to do and mod later on? Thank you so much in advance!




Absolutely no difference in power wise. They come in different tranny.



What about the B16 from the 92-93 Integra XSi, would that be the same in terms of parts needed for the swap or will it need more/less parts.


Basically yes. Unless if you get the 94 and up which comes in hydro tranny then you will need the hasport cable to hydro conversion kit. Also depending on the year on the motor since they have different OBD.

Pre 1991- Non OBD

92-95 - OBD1

96 and up- OBD2


What swap would be easiest to do and mod later on?



Well i wouldn't say "easy" or "easier" but if you're talkin about potential...then all of them are really good. High potential. For all motor , b18c5 and GSR is the best. Bigger displacement is needed for a honda to hit 12s on all motor. B16a is really hard to achieve in the 12s but it can definetly see 13s. Now for turbo is basically limitless. All b-series can hit 12s with a bolt on turbo and a semi built motor. It doesn't really take much to get it there. Just make sure that no matter what set up you have....TUNE TUNE TUNE to squeeze out every ounce of power and "reliability."

What exactly is OBD, I'v searched for it but all I find is stuff talking about converting from one to the other. What exactly is the intermediate shaft? Wouldn't the wiring harness from Hasport take care of the vtec wiring?

OBD- On Board Diagnostics.

Intermediate shaft is another name called "mid" shaft. Its about like 6 inches long that goes behind the tranny and both of your axles connect to it. Search for it. You'll see some info. Go to www.hasport.com You'll see plenty of info. Did you check out that site already?

You still need to get your wires custom from the engine bay.

I almost forgot. You will need the rear "t-bone" bracket from the 90-93 integra. Get that from the dealership. Should cost like 40 bucks.

What Tranny would be better Y1, S1, or J1 for a B16A from a 88-91 SIR1. Wouldn't that bracket come with the hasport mount kit? Or does it mount something diff? What is it a mount for? Totaly of subject... well mostly off subject, on my civic there is no tach, so I want to get an after market one or just pull one from another car. Regardless of how I get it how can I hook it up. I know that it would have to hook into something that would go at the same speed as the engine, but what would that be? I don't like not knowing where my rpm's are!

For the tach...get one from a civic SI (90-91). About the tranny...the s1 and the J1 is the best. It has the same gear ratio as the usdm type r trans which short. Good for all motor.

check the fourms - honda-tech.com and here - see if anyone is near you and will help you out.

another good thing is if you get stuck - you can always ask on fourms for help. i guess the best thing you can do is give your self time and take you time. read about the swap a lot also and go over a check list with us.
