I recently purchased a “JDM” motor

1.I noticed that it has 2 holes were the block and the tranny touch were the vin-number tags go in usdm models did JDM motors come with this ???

2. The block is stamped with a B18C this could mean GSR or Type R right? How can I tell the difference ??

3.The intake many has a p73 on it P73 is for Type R right??

4.I looked around and I saw the PS says P72 also the T-belt plastic cover is also mark P72. were else could I look for ??

5.the tranny is stamped LSD I looked inside the were the axels go and I didn’t find a anything I can see right thru it If am not mistaken LSDs are not suppt. To have any thing right ??

thanks plz help me out

If you can see straight through the trans you have LSD. The motor information is as follows, taken directly from wikipedia.

B18C:
* VTEC
* Found in: JDM Spec Honda Integra ITR
* Power:
* 200ps (200 hp) @ 7800 rpm
* 134 ft·lbf @ 6200 rpm
* Transmission Type: 5-speed standard
* Displacement: 1797 cmł
* Compression: 11.1:1 (JDM)
* Bore: 81 mm (3.189")
* Stroke: 87.2 mm (3.433")

Hooray for interweb.

the Intake Manifold on the Type R engines are different than those o a GSR. on a Type R IM...the throttle body and plenum are on the top...on a GSR the throttle body and plenum are on the bottom. A B18C stamp on the block could mean either GSR or Type R...usually the GSRs come with a black valve cover and the Type R is red.

got any pics of the engine...we'd prolly be able to tell in a heartbeat with a few snapshots.

P73 is the code for ITR, and it seems you do indeed have an LSD tranny. Since the ITR intake manifold doesn't fit on a GSR head it sounds to me like you got the Type R...is that what you were supposed to get?

Little things like plastic covers are common between some engines so since the P72 came first it's no big thing they reuse some stuff on the P73 that are not significant to performance.

thanks but those are specs i need to find out how to tell just be looking at it like unique vin numbers

Froth

JDM engines generally do not have VIN numbers. The B18C stamping in and of itself classifies it as an ITR and JDM, USDM motors generally have 5 digits such as B18C5 and B18C1 for further classification. Your motor is from a JDM ITR...That is what the specifications above state, based on the engine stamping of B18C...which is what I was trying to convey to you earlier by posting the specs.

yeah i can see right thru the axel holes but i guess i have a usdm tranny B/c it has the hole for vin plate i have fren with a jdm trany and his doesnt have them but it could be a good thing b/c usdm only came in 00 and up right with a 4.7 final drive

the IM is stamp p73 clearly and it has red Vcover could the numbers under the B18C tell me anything ? am starting to breath again for a min. i thought it wasn’t a R

free99

ok i thought b18c stand for GRS or Type R ? also the compresion test is 220 220 220 215 is this really bad ? its suppt to be 220 all across right ?

Dont itrs have a star somewhere on the head?

They can be +5 or -5 of eachother,no big deal.

it does. B18C means JDM SIR II or Type R in terms of of integras.....they dont have a number at the end like USDM. you should be able to figure out if its a SIR/GSR motor or type r by the rev limiter (type r slightly higher) and the valve cover (if it wasnt changed out) and the stamp on the head Pxx (im bad with that stuff and cant remember.)

like someone else previously said a pic would help as well.

thanks for all the help guys here is a link to pics i cant load any now cuz am at wrk !

so the comp is fine then

i also have some more question about wireing

are the plugs from a jdm ecu different than usdm ?? I was trying to wire up my motor and am not really getting anywhere my obd2 hasnes from the y7 should fit but the male from the dizzy is different, also the harness wont fit in the ECU

could it be that the motor and ECU are 97 and the harness of form a 99 I’m not sure about it but isn’t there a abd2a abd2

klungemonger

There is OBD2a and OBD2b and the ecu plugs are different but otherwise the connections for the motor itself should be the same. If you have a 97, your factory harness will only plug (and work properly) in 96-98 Civic or 96-99 Teg ecus I believe.
Can you show a pic of the dist. plug/plugs?

it appears to be a JDM ITR by those pix from the link. the harness plugs are essentially the same...however...you must rememebr that the JDM rides are RHD and therefore the plugs go to the USDM driver's side kick panel...cuz over there the ecu sits on the other side of the car. it's a lot easier to use your existing car's harness and add/extend any that are necessary. if in fact you do have a 99 civic you'd have obd2b wiring. simply acquire an obd2b-obd1 jumper harness and a p28 ecu...chip it...tune it...and enjoy 8500rpms + VTEC

free99

then the TYpe R ECU is worth less ?
yeah am awear that is a RHD but the thing is that my obd2 harnes will not plug to the dizzy the patterns are different
luky i happend to have a jumper harnes and i can get a virging ecu preaty cheap but its for d16z6 p28 would it still work fine ??

i really wanted to use the Type r ecu what would i have to do to get it wrking

I'll post pics later on tonite

jdm 98 spec tranny has 4.7 fd, usdm has 4.4 fd

free99

yeah but it looks like i have USDM tranny b/c of the vin plate holes did B18c5 come with a 4.7 or 4.4 ??

EX-T

My girlfriends has a b16a sir II in a 99 civic EX using the factory EX harness. What I did to get it to work was the distributor side of the distributor plug and re pin it. That was the easiest thing to do.

As for the p28, it will work but you might have to get it tuned before it will run right.

free99

can you explain this a lil better did you dizzy male not fit the female on the harnes ? i'll have pics of it right away tonite

there are many ways to check to see if whether or not you have a jdm gsr or itr motor...

biggest would be the IM. another way of checking is the head stamp, which also indicates the year of the motor, the head should be stamped with PR3-X

another way of telling is by looking between the Dizzy and the head and seeing if there is a green marking, like someone took a green sharpie to it.

"B18C" can be either GSR or ITR so dont let people make you think otherwise. there were no USDM model cars that came with a 4.785 FD only the JDM 98+ ITR's came with it. pre98 ITR's came with a 4.4 FD

and yes you are correct about looking thru the axle hole. if you do not see anything except the otherside of the casing, then yes, you have a LSD tranny.

what year is your car and what year is the motor?

Felliph3

B18C1 is american, jdm engines dont have that last number. Its either an Sir or an ITR

EX-T

The plug on the distributor was a 10 pin plug with 9 pinswhile the plug on the harness was an 8 pin plug with 8 pins. What I had to do was get another 8 pin distributor side plug from a buddy and repin it. The 1 wire that wasn't needed was the big blue wire b/c that s the tach signal and the ecu pulls that signal from another wire in the distributor plug in your harness.

If you want you can depin the plug from your y7 distributor and repin that one.

As a matter of fact, that is what I would do.

Take the little white thing out of the inside of your plug with a pair of needle nosed pliers and just pull it straight out then all you have to do is push each pin upwards, towards the release tab, and pull out. When you get the plug free from the y7 dizzy, do the same with the dizzy plug on the b18c. My advice is to take the dizzy off the y7 and do one pin at a time with relation to the release tab(if you take the top left ,in relation to the release tab, pin out of the y7 plug, take the same one out of the b18c plug. You'll have to cut and reconnect(solder) the black/yellow wire from from each plug b/c the pins are differenct sizes. If you have any problems doing this let me know.
