This is my first post in the integra forum. I stick to ef forum. I just bought a 90ls teg with a bad motor. I have a 94 ls motor i will install tuesday. I am only going to use the block and head from b18b. Is there any differences in b18a & b18b block and head?

 

 

Well, i got the motor out without a problem. When i started switching the harness from the old motor to the b18b i noticed the block was missing some sensors. I looks like i can take the plug out of the b18b for the one but what about the wires?

b18b


b18a

 

Does nyone know what those 2 wires are? sorry about the large pic. i don't know how to use a computer .

 

ionno but someone here does so BUMP for you!

 

It's funny. If i asked a question about "vtech" or clear tailights i would of had 30 replies already. 0h-well.

 

pics arent working.......

 

Bump for you, someone must know.

 

take misc. sensors from the b18b out. just switch everything form the b18a onto the b18b. it's all a direct fit and there are holes for everything in the both of them. switch im and distributors also.

 

The b18a has 2 wires that hook to a sensor in the block that the b18b has no place for . I am using b18a intake and dizzy.. pics seem to be working for me?? does anyone know what the 2 wires coming off the block are???

 

help

 

let me look at my friends car and i'll get back w/you he has a 94 and i have a 90..it'll be a bit

 

thanks. any help is greatly appreciated.

 

*bump* cause I'd be interested in seeing if there are any power gains from doing this.

 

It will give you about 10 horse over b18a. Do the pics work? Does anyone see those 2 wires coming off the block. does anyone know what tey are for.

 

is it running fine? if so it musn't matter much. the b18a in my gen 3 teg isn't hooked up to it. runs fine.

 

I haven't put it back in yet. I guess i will leave the 2 wires unhooked? I wish somebody had a clue what the hell it is though. I am going to put it back in on thursday.. I'll find out if it makes a difference then.

 

The two wires activate the radiator fan when the motor gets too hot.

 

Thanks. I guess i'll run the fans all the time then..
