noob. but if i get a set of hasport mounts. on my B18c do i need to replace the rear mount to an SI T bracket? or can i use the B18C one ? also can i use the JDM haness for my swap and modify it? or do i have to get usdm harness,

B18CivicEJ8

Nope. You still have to use the Si T bracket.

And no, you can't use the JDM harness at all. It is a 2 piece type of connector that will not work in your Civic because your Civic uses a 1 piece style of design. You'll have to use your stock harness and add/extend wires.

hmm so for say..TPS i can use my stock harness and just extend it and plug it in the B18 TPS? i have a D16Y8 harness do i need an Si harness?

B18CivicEJ8

Yes. No, you don't need an Si harness. Your harness already has VTEC and knock. You'll just need to add wires for IAB.

if i get an ITR intake mani do i still have to wired up the IAB?

Anon51

ITR Manifold doesn't bolt up to the GSR head. you'd have to get a skunk2 mani for the gsr. and then you won't have to worry about IAB's

94EG8

No.

xxdevilzeroxx

haha owned! thats what i meant the S2 intake mani. sorry im a D series guy. this is my first B. so what happens to the IAB after the S2 mani is installed? do i still have to leave it wired up?

nothing happens to the Iab plug... if your using a p72(gsr) or p13(h22) ecu then it will look for an IAB sensor... however, you can unplug this and it will not affect performance as much and it wont give you a check engine light..

You have 8 valves total in the gsr intake manifold. When your IAB are wired up, 4 valves are automatically closed off when you start the car (kinda like how your throttle body opens andn closes when you step on the gas pedal). However when you turn off the car, they all remain open (all 8 valves). As soon as you hit around 6,100rpms or so, the 4 valves open up and allows more air flow so you get more power.. the function of the IAB is to create low end torque for daily driving..

sounds fun to wire up/.. its a 94 spec ob1 B18C. got any tips on how to wire it up?? anyone wanna buy it? lol seems easyer to get a skunk mani..is it a JDM thing only? or USDM has it too?

-__-

^^yeah get the skunk2 mani. saves you the trouble of wiring the IABS and the manifold design is way better. to me the stock GSR manifold is an eyesore

other than that the swap is easy cuz u have a D16Y8 harness

xxdevilzeroxx

thanks! so i dont have to add the IAB wires to the harness if i go Skunk..or can i just take the IAB plate and bolt it back together.? btw thanks guys for the real help. and not stupid *** comments i see all the time when ppl post!!!!!!!!!!

raidacaipo

its not that hard to wire up.. just look at the diagram and stick a wire into the ecu pin on back and bring it straight up into your iab sensor.. or you can find a wire that your not using and repin it to the iab: http://www.phearable.net/tech/wiring/obd2pinremoval.jpg

Heres another link where the iab is yellow #26: http://www.phearable.net/tech/wiring/wiring.96-98_2.jpg

*You dont even have to add IAB wires period if you dont want on the gsr manifold. If anything all 8 valves will automatically stay open thus you get a little bit more high end power but less torque.. (trust me I used to have a jdm gsr and I really couldnt tell a difference whether it was wired up or not.. or maybe I do? well according to my "butt dyno")

If you wanna see if your iab works, simply wire up an iab wire from the iab sensor to your ecu. Then have your friend start the car. Look on the right side of your manifold. You will see a gold looking Bell shaped piece that connects to your vacuum lines.. it will slowly move meaning you wired it up correctly. What it is doing is its closing the 4 valves like in this diagram: http://img233.imageshack.us/img233/1624/iabtb9.jpg

I also switched over to a skunk2 pro series intake manifold and the high end power was there.. so I thought it was worth it..
Heres a good link if you want to change your gsr manifold to a skunk2 :http://technet.ff-squad.com/how-to/sk2im/

thanks alot man!!!!

by the way can i use my stock EX trans bracket for the B18? or do i also have to use the SI one? because i have an EX 99 motor. i know i need the T bracket. im using hasport mounts. what other bracket do i need? or can i use my stock brackts

raidacaipo

well you can use the stock gsr bracket thats on your tranny already with the stock ex motor mounts

xxdevilzeroxx

damn the GSR didnt come with any of those brackets. i cant use any of the SOHC brackets?

B18CivicEJ8

No. You have an EK, you have to use a rear T bracket from a 99-00 Si. There is no way around it. A SOHC trans is different than a B series trans.

Proof:

Hasport

you can use the SOHC 5spd transmission bracket

you will need a 99-00 SI block bracket on the timing belt side

raidacaipo

your confusing the original poster.. hes asking if he can use the gsr or stock ex transmission side brackets for his motor mounts, not the rear.. I already answered that for him..

raidacaipo

B18CivicEJ8

My bad. I mis-read what he was asking. You are right...

you can use ALL of your RUBBER mounts on the B-Series motor. The only mounts you need to change are the upper driver's side mount (the one that had the 2 prongs sticking out of it.) the front transmission torque mount bracket and the rear "T" bracket. The front transmission torque mount bracket can be from any b-series hydraulic transmission.
