Ok i thought i would Write this up since there are soo many different Questions for these cars. IF you want to sticky this feel free too.

All B-series transmissions are interchangeable. you can use any B series transmission as long as it is on a B series engine.

92-95 EG & Del Sol swaping a 88-91 JDM B16a, 92-93 B17a, 90-93 B18a

Transmission: Thses engines come with japanese or american market cable clutch transmission including S1, J1,A1, Y1,YS1. To use them you will need a conversion harness. Hasport has one Part number M96-CC. Or you could use a Y21, Y80, S80, S4C Hydraulic Clutch Transmissions.

Mounts: A combination of stock civic and integra mounts can be used if a Hydralic B series Transmission is used. You will need to chance the bracket under the timing belt and on the rear of the engine for ones of the appropriate year. Or you could use a Hasport mount kit part #EGB1 with the cable converision harness if you wish to use a cable transmission.

ECU: Using a OBD-O ECU is not a good idea. A PR3 from 92-93 Integra RSI or XSi, A p30 or modified P28 for a B16a, a P61 or modified P28 for a B17a, or a 94-95 PR4 for a b18a are acceptable.

Electrical Differences: CX and VX need to convert to a 4 wire o2 sensor. Non Vtec models need Vtec Solenoid and Vtec Pressure. all models modify stock harness to fit. add a knock sensor except when using a chipped P28.

Axles: 90-93 integra axles, 94-up integra axles, 94-97 Del Sol Vtec axles, or 99-00 Civic Si Axles. Note the intermediate shaft seal in the left side of transmission is different for 90-93 Integra Axles. Depending on Axle transmission Combo, It may have to be changed. Hasport Part#: EGBAXCMP

Shift Linkage: 94-up Integra Linkage for civics. 94-97 Delsol Vtec linkage for Del sol.

Upper Radiator hose: For B16a and B17a use 94 delsol Vtec. For B18a use 94 integra LS

Lower Radiator hose:94 del sol Vtec

Throttle cable: B16a and B17a use 92 GSR; B18a use 90 Integra LS

Clutch Hydraulics: Stock

Air Conditioning: 94-95 Del Sol Vtec AC bracket

Special Instructions: For 1st Gen B16a's replace distributor with one from a 92-93 GSR, 94-95 GSR, 94-95 Del Sol Vtec. For 90-91 B18A's replace Distributor with one from a 92-95 Integra B18a or B18b. Injectors need to be replaced in both engines with ones from the models listed above.

Special Considerations: The First gen B16a engines are cheap, best bang for buck. 92-93 B18a's and GSR's have compatible electronics and make easy for a swap.

92-95 EG & Del Sol with a 94-2000 Integra LS B18B Engine.

Transmission: These Engines come with Hydraulic clutch transmissions including Japanese or American market Y21, Y80, S80, AND S4C. Japanese or American market S1, J1, A1, Y1 or YS1 cable clutch transmission with Hasport cable conversion kit part # M92-CC can be used.

Mounts: A combination of stock and integra mounts can be used if a hydraulic B- series tranny is used. on some 96 and up engines you may need to change the bracket under the timing belt and on the rear of the engine for ones of the appropriate year.

ECU: p75 from a 94-95 Integra

Electrical Differences: CX and VX need to convert to 4 wire o2 sensor. All models modify stock harness to fit.

Axles: 90-93 integra axles, 94-up integra axles, 94-97 Del Sol Vtec axles, or 99-00 Civic Si Axles. Note the intermediate shaft seal in the left side of transmission is different for 90-93 Integra Axles. Depending on Axle transmission Combo, It may have to be changed. Hasport Part#: EGBAXCMP

Shift Linkage: 94-up Integra linkage for Civics. 94-97 Del Sol Vtec linkage for Del Sol

Upper Radiator Hose: 94-Up Integra LS

Lower Radiator Hose: 94 Del Sol Vtec

Throttle Cable: 94 Integra LS

Clutch Hydraulics: Stock

Air Conditioning: 94-95 Del Sol Vtec A/C bracket

Special instructions: Using OBD II Ecu requires involved wiring modifications. Generally if the ECU you choose does not use the same plugs as the stock ECU, an Adapter harness will cut down on alot of potential problems

Special Considerations: Nice motor, Smog Legal, and excellent base for turbo car. Smog Legal in CA

92-95 EG and Del Sol with 94-2000 GS-R B18C(including Integra Type R) & 93-97 Del Sol Vtec & 99-00 Si B16a2

Transmission: These Engines come with Hydraulic clutch transmissions including Japanese or American market Y21, Y80, S80, AND S4C. Japanese or American market S1, J1, A1, Y1 or YS1 cable clutch transmission with Hasport cable conversion kit part # M92-CC can be used.

Mounts: A combination of stock and integra mounts can be used if a hydraulic B- series tranny is used. on some 96 and up engines you may need to change the bracket under the timing belt and on the rear of the engine for ones of the appropriate year.

ECU: Use ecu that came with the Engine with proper wiring modifications. For those who do not wish to use OBDII ecu's. For the B16a2 Si motor use the JDM P30 Ecu. Other wise you may use a Chipped P28 with the Proper Programing.

Electrical Differences: B18C1 add air intake Bypass wiring. Cx and Vx need to conver to 4 wire o2 sensor. Non Vtec models need to be wired for Vtec solenoid and Vtec Pressure. All models Modify stock harness to fit. add knock sensor if you are not using a Chipped p28 ecu. Hasport Harness for B18C1(GSRmotor) part #EGDX-GSR

Axles: 90-93 integra axles, 94-up integra axles, 94-97 Del Sol Vtec axles, or 99-00 Civic Si Axles. Note the intermediate shaft seal in the left side of transmission is different for 90-93 Integra Axles. Depending on Axle transmission Combo, It may have to be changed. Hasport Part#: EGBAXCMP

Shift Linkage: 94-up Integra linkage for Civics. 94-97 Del Sol Vtec linkage for Del Sol

Upper Radiator Hose: For Engines using b16a or Type R Head use 94-97 Del Sol Vtec Hose. For Engines with GSR head use 94-up GSR hose

Lower Radiator Hose: 94 Delsol Vtec

Throttle Cable: For Engines with B16a head, use 94 Del Sol Vtec. For Engines with GSR (B18C1) head use 94 GSR. For Engines with Type R head Use 98 Type R

Clutch Hydraulics: Stock

Air Conditioning: 94-95 Del Sol Vtec A/C Bracket

Special Instructions: Using OBDII ECU involves wiring modifications. Generally if the ECU you choose does not use the same plugs as the stock ECU, an adapter harness will cut down on alot of potential problems.

Special Considerations: US motors are smog legal as long as the motor is from the same year or later. Japanese type R motors are very potent and wiring is relatively easy with ecu adapter harness. The B Series engine swaps into these year vehicles are by far the easiest. there are honda mounts available to bolt those engines directly in and the wiring is by far the simplest. The majority of people opt to put in a B18C, B18B, or 94-95 Del Sol B16a and those bolt in directly using Del Sol Vtec Mounts. the Del Sol mounts are the same as the 94-up Integra mounts with the exception of the A/C bracket.

92-95 EG and Del Sol with 94-2000 H22a, H23a Prelude and 96-2000 F22 Accord

Transmission: All 92-up Prelude 5-speed Transmissions and 92-up Accord 5 speed Transmissions. Transmissions with ATTS will require major wiring modifications

Mounts: Hasport mount kit EGH1

ECU: Use the ECU that came with the engine with proper modifications to wiring. For 96 and up Engines either back date electronics and use appropriate OBD 1 ECU or use adapter harness and make proper wiring modifications.

Electrical differences: CX and VX need to convert to 4 wire o2 sensor. Non Vtec models need to be wired for Vtec solenoid and Vtec Pressure. Add EGR soilenoid and EGR valve except for VX. All models modify stock harness to fit, add air intake bypass wiring, and add knock sensor. Hasport offers a harness part # EGWH22

Axles: Use 90-up Accord Intermediate shaft with 90-93 Integra Axles. To use Prelude Intermediate shaft a shorter left hand axle with a female inner joint must be used. To construct the proper left hand axle use 94 GSR left hand axle inner and outter joints on a 86-89 integra axle shaft. Hasport Part#: EGHAXCMP

Shift Linkage: These Transmissions use cables instead of linkage. The Shifter Mechanism and cables fron these vehicles may be used, 90-up Accord 5 spd or 92-up Prelude 5 spd cables and linkage. This will require some cutting and drilling.

Upper Radiator Hose: 90 Integra LS, Trim to fit

Lower Raditor Hose: 94 Del Sol Vtec

Throttle Cable: 98 Prelude

Clutch Hydraulics: Stock

Air Conditioning: Not without some custom Fabrication

Special Instructions: The mounting bracket on the right hand frame rail will need to be removed or it will interfere with the shifter assembly. A thin fan or pusher fan will have to be used with the radiator. Radiator Should be upgraded to a Del Sol Vtec Radiator for increased cooling.

Special Considerations: Suspension and Brake upgrades is a good idea.

96-2000 Civics and 96-97 Del Sol with 88-91 B16a, 92-93 B17a, and 90-93 Integra B18a

Transmission: Thses engines come with japanese or american market cable clutch transmission including S1, J1,A1, Y1,YS1. To use them you will need a conversion harness. Hasport has one Part number M96-CC. Or you could use a Y21, Y80, S80, S4C Hydraulic Clutch Transmissions.

Mounts: For Civic, a combination of stock 99 Si and Integra or Del Sol Vtec Mounts and brackets can be used if a hydraulic B series tranny is used. For Del Sol the Del Sol Vtec Mounts and brackets can be used and you will need to change the bracket under the timing belt and on the rear of the engine for ones of the appropriate year. When using B series engines with cable clutch transmissions you will needt to change the bracket under the timing belt and on the rear of the engines of the appropriate year and use the Hasport cable conversion M96-CC.

ECU: By far the easiest ecu to use in most situations is the p30 from the 96-97 Del sol Vtec. only a few modesl of the 99-00 civics need the 99-00 Si ECU. For more info see Elctrical Differences below. Chipped P28 can be used if a OBDII to OBDI harness is used. May not be smog legal in CA.

Electrical Differences: Wiring Differences can be significant; here are a couple of guidelines. the electrical modifcations depend entirely on engine wiring harness, it is generally best to use the stock harness and modify it to fit. If the ECU you choose does not use the same plugs as the stock ECU, an adapter harness can cut down on alot of potential problems.

Axles: 90-93 integra axles, 94-up integra axles, 94-97 Del Sol Vtec axles, or 99-00 Civic Si Axles. Note the intermediate shaft seal in the left side of transmission is different for 90-93 Integra Axles. Depending on Axle transmission Combo, It may have to be changed. Hasport Part#: EGBAXCMP

Shift Linkage: 99-00 Si Shift Linkage for Civics; 94-97 Del Sol Vtec linkage for Del Sol

Upper radiator hose: For B16a and B17a use 94-97 Del Sol Vtec. B18a use 94 Integra LS

Lower Radiator Hose: Use 94-97 Delsol Vtec

Throttle cable: B16a and B17a use 92 GSR. B18a use 90 Integra LS

Clutch Hydraulics: Stock

Air Conditioning: 96-97 Del Sol Vtec A/C bracket

Special Instructions: Using Non OBD ECU is not a good idea. Using OBDI ECU requires an adapter harness or involved modifications to the harness.

Special Considerations: Best bang for the buck. but not going to be smog legal in CA.

96-2000 Civics and 96-97 Del Sol 94-2000 H22a, H23a Prelude and 96-2000 F22 Accord

Transmission: All 92-up Prelude 5-speed Transmissions and 92-up Accord 5 speed Transmissions. Transmissions with ATTS will require major wiring modifications

Mounts: Hasport mount kit EGH1

ECU: Use ECU that came with the engine with proper modifications to wiring. for 92-95 engines either up date electronics and use appropriate OBDII ECU or use adapter harness and make proper wiring modifications.

Electrical differences: Wiring Differences can be significant; here are a couple of guidslines. The electrical modifications depend entirely on engine wiring harness, it is generally best to use the stock harness and modify it to fit. If the ECU you choose does not use the same plugs as the stock ECU, an Adapter harness with help cut back time on alot of potential problems.

Axles: Use 90-up Accord Intermediate shaft with 90-93 Integra Axles. To use Prelude Intermediate shaft a shorter left hand axle with a female inner joint must be used. To construct the proper left hand axle use 94 GSR left hand axle inner and outter joints on a 86-89 integra axle shaft. Hasport Part#: EGHAXCMP

That is it for now. when i get more information on K20 swaps i will write one up for the K20 Until then this should help alot of you guys. Now im tired since it took me 3 hours to write this. so put it to use and Enjoy the useful information. Im out JDMLyfeStyle.

 

Well since this gets asked almost daily, I have decided that making a thread to showcase, if you will, the swaps.

Some intro swap information

General swap info and tips

This could be better covered by someone with more swap experience, but I'll put in my $.02. Do it from the top. Just because more people have access to the tools and locations where putting in a swap from the top is easier. Also, make sure you have some way to crack the axle nuts loose. Air tools are a lifesaver when you have to turn bolts in a job like this, as is a torque wrench and a GOOD set of sockets.

If you can follow directions on here and unbolt things and rebolt them with a little wiring, you can do a swap.

JDM Swaps

Honestly, unless these come from a friend in Japan, you're taking a gamble every time. You have no real way to know how many miles are on the engine, nor how it was treated. Just keep that in mind. It has not been proven (no matter how many claims) that these JDM motors make any more HP.


Where to find them

First of all, if you are looking for a USDM motor, I'll suggest local junkyards. They are probally your best bet, as you can look at what you're getting instead of having to order it. Many people on here have bought swaps online.


Possible Swaps

Now before someone jumps on me and says anything is possible with enough time and money, I know. These are going to be fairly straightforward options with the pros/cons.

D series swaps
These are fairly inexpensive and come in a variety of Civics. IMHO, these are the easiest swaps to drop in. I also don't want to hear a bunch of whining about the opinions on power levels. Of course there are going to be some exceptions to the rule.

Pros
Inexpensive
Decent potential (200 whp or so on stock internals)
OEM parts are cheap
More than enough for most people
The best D series come with ~130 hp tops
Optional factory LSD in the JDM D15B

Cons
Not as much potential as some other motors
Transmission not geared for accelleration
Don't respond to bolt ons well
Only way to get real power out of them is FI

B16
These can be found in the JDM SIR and SIRII (among other JDM cars, which I don't claim to know all of which it came in) as well as the USDM 99-00 SI (EM1) and the 99-00 Canadian SIR.

Pros
160 hp stock
High RPM power
Fairly inexpensive
Good transmission
DOHC VTEC

Cons
113ft/lbs torque (very little more than a D16z6 stock)
Without knowing what you're looking for you can end up with a high mileage JDM model
Under 4k or so it feels just like a D16

B18B
This is the motor in the non Type-R and non GSR Integra.

Pros
Good torque for a 1.8L (127 ft/lbs)
Inexpensive (even cheaper than a B16)
142 hp (more than any stock D series)
Boost heads love them

Cons
No VTEC
Longest B series transmission

B18C1 (or JDM B18C)
These come out of an Integra GSR.

Pros
Good Hp and TQ numbers (170, 121 ft/lbs respectively)
DOHC VTEC
Tons of potential
High revving

Cons
Expensive
Becoming moreso as people keep scooping them up
Slighty longer tranny than the ITR and B16

B18C5 (or JDM B18C)
This is found in the Integra Type-R. IMHO this is the best swap for a Civic.

Pros
GREAT HP and TQ numbers (195 and 134 ft/lbs)
High revving
Hand built motor from Honda
Optional factory LSD
Best transmission for a B series from the factory
Red valve cover

Cons
EXPENSIVE
If JDM ITR is used, the 36mm axle 32mm hub problems occur

B16B
This is the motor found in the Civic Type R found all over the world.

Pros
185 hp 117 ft/lbs
High revving
Good top end power
Red valve cover

Cons
Expensive- almost as much as an ITR for lower performance
Very little torque still, have to rev the motor to make power

B20

Pros
Great torque (133 ft/lbs)
good boost motors
inexpensive
B20z=146hp

Cons
Thin cylinder walls
Have to peice together a swap for a Civic (can't drop it in with a B20 tranny)
Won't pass BAR (light truck motor in a car)
Low hp in the B20b(126 hp)

H22/JDM F20B

Pros
200 hp
H22=156 ft/lbs torque
F20B=145 ft/lbs torque
Great torque
DON'T WEIGH THAT MUCH MORE THAN A B SERIES SWAP!!

Cons
Harder to install than a B/D motor
transmission feel is vague IMHO
Less info out there for the swap (aka, less experience as they are less common)
Price of swap is comperable to a B18C5 after everything is said and done (mounts, etc)

K20
This can be found in the new EP3, the RSX (base and Type S) as well as other cars across the world (RSX R, etc). This is the future of the swap IMHO. There is a writeup on installing one of these in one issue of Sport Compact Car magazine (June 2004 I *think*)

Pros
200 hp 158 ft/lbs torque (RSX R)
I-VTEC
Respond VERY well to bolt ons
6 speed transmission
Most have very low miles

Cons
Still super expensive
More difficult swap than a B or D

Well, there you have it people. I've outlined some of the pros cons on some of the most popular swaps.

Most of these HP/TQ numbers were taken from Hmotors online if I didn't know them. Don't bite my head off if they aern't correct. I don't claim to be a walking encyclopedia, so I have had some help.

 

there is a proven difference in power between usdm and jdm... its about 10hp cause they run .5 higher compression on almost every engine... just look it up...

 

so if they run .5 higher compression then USDM motors would be better boost motors?

 

and there is only a .2 compression difference between usdm an jdm in b18b motors btw

 

97civicEXVTEC--Yes, lower compression is typicaly better for boost, however you can use stock USDM pistons or stock JDM pistons with boost...you just need a great tune...I've personally seen a dyno run at over 320 horsepower at the wheels on stock internals, tuned with hondataon a b18C1. The lower you go on the compression of your pistons, all the more boost you can run. To see numbers like 20+ lbs. of boost, you'll need at least 9.5:1 compression pistons...I'm sure there are people out there running high boost ( above 14.7psi ) on full stock internals, but they either spent 1k + on engine management and 1k+ on tuning; or will have fried piston rings and gaskets within the next 5k miles.

The moral: you can achieve huge dyno numbers on stock internals with an AMAZING tune, but IMO I'd rather not risk it and do it right the first time, i.e. forged internals, and 9.1:1 or 9.5:1 comp pistons

 

Dude I Freaken Love You The Search Link Does Work I Love This Faq!!!!! Thanks
