Yea, i've got a 1990 civic with b18a1 block, b16a2 head, and turbo kit. Both the block and head are built. I was driving two days ago and all of a sudden it sounds like i'm running on 3cylinders. So i get home, and yup.. pull out the spark plug wire for cylinder 3 and it doesn't bog out. All of the others bog out. I'm definately gettin spark, and i changed the sparkplug for cylinder 3. I'm thinking i may have a bad fuel injector or a bad piston. My main concern right now, is that i didn't build this motor nor have i ever built a motor before. I am good with tools, i've had an ek and an eg before this. I've swapped out motors before. My question... if my b18a1 block is bad, can i just swap it out for a b18c block? i never liked the idea of having LSVtec. I'm guessing the b16head should bolt on directly to the gsr block correct? i'm sure i have arp headstuds holding on the head... so those should be interchangeable as well correct? i definately don't wanna use a b16 block nor a ls block again. 2nd thing, will my hasport mounts work? i'm using a cable transmission right now and i want to continue using the cable transmission even with the b18c1 block. So will the mounts work on the newer block? thanks a lot for the help guys.

 

you should make sure you know what the issue is before switching blocks. there are a number of problems that could cause a dead cylinder. but to answer your questions the b16 head will fit on the gsr block with out any problem. im pretty sure that the arp studs will tranfer over but you may want to look into it to make sure. also your mounts and tranny will work fine.

 

awesome thanks for the help. What else could cause a dead cylinder? i was thinking possible piston ring but i haven't had the time to pick up a compression tester. so far i've checked the spark plug, spark wire... so i've got the injector and compression left to check. If there are any other things i need to kno, lemme kno as i want to find out asap.

 

Awesome to kno about the interchangeability. I noticed that on hasport it says the mounts were designed for earlier b-series but can be used with the newer b-series with simple hardware. u kno what that maybe? i don't wanna get stuck with the motor outside of my car too long. So i checked the Spark plug,spark wire... i've gotta check the injector and compression next. how do u check injectors? they're 330cc obd1 and have a resistor box so i'd think they're low impedance.

 

So you've checked for spark, and there IS spark on that cylinder?

I don't think you're supposed to run the resistor box with OBD1 injectors. That could be the main problem.

 

well i'm not too sure if they're obd1 injectors. my friend said they were and brought an obd1 injector to replace the "bad" one but it didn't change anything. i figured the one he brought is obd1 and mine is obd0 thus meaning i need an obd0 injector to make everything work. This is my first time working on obd0 with a conversion to obd1. i figured everything would be just like using obd1 but it's not. if it were obd1 i think this would be figured out already. so... can i remove the resistor box and just use obd1 injectors? i've got like 2 sets of obd1 injectors that don't require a resistor box.

in the amount of time you have spent on these posts, you could have ran down to the auto parts store, bought or rented a compression tester, tested the engine, and returned the part.

 

if ur injectors r OBD 0 u need a resistor box for sure

 

just got the compression tester, and as far as me running to the store.. this is my daily driver so i've been stuck at home. i'll come back with some numbers. thx soo much guys

 

who said anything about your car? i said, "ran to the store".

 

ok man, couldn't get it compression tested tonight. Ran into some problems. i did get to smell my spark plug that was in cylinder 3. it's the one i installed after i thought the spark plug was bad, i've had the car idle for maybe 15 mins total since i've installed the new plug and i smelled it and couldn't smell and fuel on it. all the other plugs smelled like fuel so i figure that injector is not working. i'll let u kno wassup tomorrow, thx everyone on h-t

 

Ok, next question.... I have a set of obd-1 injectors that i would like to install. would i need a different fuel rail since it looks like i have a stock b-series obd-0 fuelrail. I'm sure my friends have an extra obd-1 fuel rail and injectors somewhere. is there a way i can eleminate the resistor box?

 

To eliminate the resistor box, solder all the wires going to it together.

Not kidding.

 

which wires? all of the positives together and all of the negatives together.... or everywire together? i'm good with soldering, it's 2nd nature to me.

 

Does it run at all?If so,put you a long screwdriver on each injector,one by one,and your ear at the other end...you should be able to tell if inj are working by the rapid clicking.And OBD1 injectors do not use a resistor box.Also a bad valve can cause a dead cylinder,but it sounds like something simple like the one OBD1 injector.

 

I would like to add that if it is a broken piston or ring you will normally get massive oil fouling on that plug, and do the compression test any way just to be sure.

 

i got no oil fouling.... and i'm using obd-0 injectors right now. They're upgraded but i want to convert to obd1 since i have a couple friends with some. could i just use some dsm's since i already have the resistor box?

 

if the DSM injectors are Low Impedence then you can still use the resistor box. It has nothing to do with OBD0 or OBD1 it has to do with the impedence of the injector, if you are using High impedence injectors you remove the resistor box if its Low impedence you have to use the resistor box.

 

obd1 and up cars use high impendence injectors. Except for the prelude.

 

OBD2 Preludes are High Impedence.

 

Yes they are, I meant that obd1 preludes use low impendence injectors but you knew that already. I should have looked at that before posting my bad.
