hey guys! well im pretty new to this forum...

not that much of a car geek...

but my b18c1 just recently blew up on me... and i've decided to swap it with a jdm b18c type r.

i know you guys might tell me to do more research but i have... and i can't find what i need to know...

i was wondering if my usdm gsr harness will plug onto the jdm type r engine....
and i was wondering if my ps, ac, and etc will be able to work with the engine. or do i have to buy the type r parts?

i'd really appreciate any type of feedback. thank you.

 

For the most part the connectors are the same. There are a number of things missing from the JDM engine that'll leave connectors hanging:

No CKF, VTEC oil pressure switch, IAB, or EVAP purge.

You can eliminate the need for the CKF:

You can either lie to the ECM about the VTEC switch (search VTEC pressure switch bypass) or swap in a USDM VTEC solenoid that has it.

IAB you won't need with the Type R intake.

Type R intake has no EVAP solenoid - so again depending upon which ECU you may get a code.. if you get the ECU that comes with the 'R' it won't complain about the VTEC switch, EVAP, IAB, etc will it?!

I'm about a day away from dropping that same engine in a '96 GSR..

What fun.

 

thanks alot mark

i really appreciate it!

just need to find a good engine now lol xD

 

Good luck!

 

dude mark!

whenever you do drop that engine in.. you mind showing me how you did it... pictures would be awesome too!!!

lol

 

Have fun dropping the c5 in guys. I think I may do that to my GS-R also.

 

jeryhawj, how did you gain the ability to create threads? The website told me I have to have at least 5 posts and be a member for 15 days to create threads. It shows you only have 3 posts also haha...I'm confused.

 

LOL dude! i have no idea!!! i started this thread as soon as i registered tho! haha... this website is freaken awesome!!!

btw... we're dropping in a b18cR not c5

 

damn... wish i could go kswap xD

 

So guys... i need some help. finally done with the transplant.

got the jdm itr motor in my car. using the my old obd2 wiring harness.

car has very bad idle and burns really RICH...

i have no idea what the problem is.

but the car does have Skunk2 cam gears and a toda timing belt.

could it just be my timing is off? my brother and i adjusted the timing like a million times and we get the same results.

the car barely has any power... driving past 2500 rpm causes car to feel like stalling. the car eventually stalls.

and yes... using my wiring harness i have like 2 or 3 plugs left unplugged.

any help would be greatly appreciated!

 

Using the USDM GSR ECM or a JDM one that came with the engine?

 

usdm gsr. running a chipped p72 with my conversion harness. but im pretty sure its not my ecu... couldnt be.

 

What's a good list of things that make a car run rich?

Plugged air filter?
Non-standard sized injectors?
The original GSR had the EVAP system that allowed a small but steady stream of air in.. ?
O2 sensor not well... AFR is off?
Cat plugged, more restricted exhaust?

?

 

air filter is good.
using my old gsr injectors.
(dunno what you mean "The original GSR had the EVAP system that allowed a small but steady stream of air in")
02 sensor is good.
using my gsr exhaust system.

so i guess ill look into the evap system?

 

Well - I am speculating here.. but the EVAP system taps the fuel tank and feeds that's into what looks like a small 'regulator' similar in appearance to the ones on your BBQ (you know, regulates pressure to 2 psi or so..). I think it works in a similar way, and when pressure builds beyond the limit, it allows the pressurized vapor to escape to the EVAP cannister. On mine, the little regulator is black plastic with a red cap.

From there it goes to the EVAP cannister, and from the cannister to the EVAP purge valve, which regulates a small but steady stream of air into the intake. It can detect a malfunctioning EVAP system in part by not seeing the changes it expects in manifold intake pressure as it exercises the EVAP purge valve.

So - my guess regarding this is that with the non-GSR intake and no EVAP purge solenoid, this additional steam of air isn't present but the ECM is assuming it is...

Therefore, less air in with the same amount of fuel; e.g. rich.

Just thinking out loud...

OTOH, it's monitoring with the MAP and the O2 sensor so you'd think it could compensate.. but making up for missing components may be outside of it's ability.

That's why I asked which ECM was in use, because the JDM one wouldn't have this problem - if in fact that is what's happening.

my brother has an integra with jdm b18cR as well. and his car runs better/stronger on a obd1 p72 ecu. he originally had the p30 or w/e the jdm ecu was.. there isnt any difference tho... so could not be ecu. i'm definitely sure about this.

 

Can you end up with a rich running system if the timing belt is off a tooth? Does it have adjustable gears? Is the valve lash set correctly?

Mark

 

im not really sure.. all i know is that i have skunk2 cam gears. dunno whether they're adjustable or not. and my brother and i have been tweaking the timing belt like a billion times... we get same result... or is adjusting the timing that hard? btw... i appreciate how hard you're trying to help me. thank you.

 

I think a tune will smooth things out. What basemap is burned onto the chipped P72?

 

yea... but getting it to a tune up shop is the difficult part. -_-' especially becuz the closest one is in oklahoma and i live arkansas....

about the chip... i have no idea... but car still feels the same even if i put my original obd2 p72 ecu in.

 

Arkansas??
Go to Wichita,ks Fusions they do an amazing good there!!

Im planning on doing the 96-96 swap here within 2months not stock tho ;]
