B18c1 Swap

[DjHonda247]

Hello all and thank you in advance for helping me out a bit. I was curious if anyone has any information on www.totaljdm.com or www.total-boost.com ? I am planning on buying a B18 motor and I don't want to get screwed in the process. Any info would help if you all have it.

Also, when I do buy a GSR motor what do I need to complete the swap into a 2000 civic ex? Someone told me (lower timing belt mount and a/c mount from a 00 si.) Timing belt, water pump, act extreme clutch? Anything else to complete the swap? Thanks

well first total jdm sucks balls! lol just kidding herman is an awesome guy and will not screw you over i know him personally and know the quality of his stock um.. first hand. You wont be sorry going with them

gsr you will need an ac bracket (um if you use ac) you'll need a rear mount bracket. you can get it from an SI and a harness (you can use an SI harness, but you have to use an SI ecu) if you dont want to do that you'll have to wire up the harness for the gsr into you're ex becuse the gsr plugs into the fuse box and is in two peices unlike you're one piece ex harness (hence the si which is in one peice) im sure i missed some people will add.. ask specifics and i can help you more.. pretty much the same swap as you

lol ok no you dont need a new harness(i have a 98ex and am currently in the process of swapping a gsr, and ive swapped a gsr into a del sol...no problem), you just dont use the harness from the gsr. the only thing you will have to do is wire in a knock sensor and a crank angle sensor(depending on the year). Regardless of whetther you use ac or not, you still need the front AC mount. you need the drivers side top mount from a civic si(this is the part that bolts to the motor), you can use your stock traingular bracket that goes from the mount to the motor. You need the rear motor mount bracket from a 99-00 si, you need any b series shift linkage(except del sol si) you can use the 98+ gsr ecu, however like i said you will have to wire up knock and crank angle sensors.
as for the clutch...you can use any type of clutch you want, i prefer action cause thats my brand of choice. act's are metallic and they are hard on flywheels thats why i dont use them.
you will need a vtec timing belt and a vtec water pump. people dont think theres any difference, but there are trust me.
you dont have to change injectors, the stock gsr came with the same injectors that are in your ex. the only difference in injectors was on type r and prelude.
let me think a little more im sure ill come up with more.

He also has to wire the IAB's. He can use a 96-99 GSR ecu as they are all OBD2a. He will need a timing belt specifically for a GSR, not just a VTEC. The GSR block is taller than the B16 block.

no shit...i figured he knew that one...ok but you have one issue...his car is obd2b. so your theory is flawed. hed have to use a 2000 or newer gsr/type r or si ecu...obviously the type r and si wouldnt run the car right. the car would throw 2 codes right outta the box if he just plugged it in and tried to run it,
1:knock sensor
2:crank angle sensor.
neither of which his car is wired for. Not wiring in the IAB will not cause any issues. now like i said, he doesnt need to change any of his harness, this can all be wired in if need be. if hes worried about smog(which i doubt) he needs those, but if he doesnt, then i would just get a p28 and do hondata, uberdata, something, whatever he can afford. my preference is hondata.
Now you can take the butterfly plate out completely, or have someone modify it to not use them...easy..you dont need them anyway(unless your worried about smog), or get a skunk2 or jg manifold. i like the skunk manifold cause it isnt outrageous and doesnt require monster amounts of air flow like the jg. Thank you for claryifying that for me though, he does need to run a gsr, ITR or CTR timing belt. which, are all the same.
btw b18's are only higher in deck height than the b16a blocks...the b16b block has the same deck height

According to what I've seen, the 96-00 Civic EX uses the P2P ecu, which is OBD2a. The 99-00 SI was OBD2b, but I thought the lower model civics were not. I figured honda wouldn't want to rewire the car, and make all kinds of changes when the entire car was changing the next year anyways. And since you were going through what he needed to wire, I figured he didnt know, so I added the IABs...lots of people want them anyways.

[Hybrid_Coupe]

Oh i see, that makes sense, we just dont wire them in and take them out generally. Yeah its still a p2p in the 99-00 however all they did was cahnge the plugs, they really didnt rewire it.

[simplegreen]

or they were just retarded in my car's case.. 99 ex with a obd1 distributor in it.. with the obd1 plugs wired into a obd2b harness. and no im not kidding.. i have valid eye witness' lol fucking sucked.. which is when i scraped that and just threw in a 00 si harness

[DjHonda247]

Well it seems as if everyone has a different way of installing a gsr. I will put all our heads together and make a kick ass motor then. Thanks for the advice.

[Hybrid_Coupe]

no prob man...good luck. Wow...you got lucky all obd1 plugs? or did you mean obd2a? cause if everything in your car were wired for obd1 i would be stoked if i were you. No but the majority of the plugs under the engine compartement are identical from obd2a to obd2b. the only difference is which connector it uses to connect to the ecu.
