Whats up guys ive searched to find no threads to answer my questions. I wanna swap in a Stock B20b in my Eg coupe but hear i need parts off of another B series motor like the intake manifold, exhaust manifold, ect. Can anyone confirm this what will i need to do this swap. Later on down the line i will do B20 Vtec but i dont have cash right now that why i plan to swap in a stock B20 now.
I know for sure i will need
B20b Motor
B series tranny
B series axles
Hasport mounts that i have already
Which distributor
Which Intake manifold
Which Exhaust Manifold
Im pretty sure ill need a conversion harness to go from obd1-obd2

 

bump

 

Foe some reason people don't respond to b20 questions
I'm doing the same..
If you're gonna get a conversion harness then you can use the distributor the engine comes with.. You can get an ls intake manifold.. I'd say go with a b16 tranny.
Hope that helps..

you need any hydro b-series tranny, 94-01 integra axles.
use a 94-95 Integra LS distributor.
94-95 OBD1 LS intake manifold.
94-01 Integra Exhaust manifold.

Use your stock ECU and have it re-programmed instead of using the obd2 ecu and buying the conversion harness.

the reason no one responded, is that this information has been covered over a million and one times.

Sorry but I've searched like a million times and never find any real info..
A link would stop all these q's.
I have a couple myself... the axles from my b16 will work right? Also, if I run a ls ecu should I use the ls injectors of the b20's? Thanks...

 

bump, which wire harness should be used? Will a p75 ecu work? What mounts are required?

 

Ok, since nobody else is being really helpful................

For a B20b to be put into a d-series chassis (your civic) you are going to need some decent motor mounts. You can get those anywhere and it doesnt have to say "Hasport" on them either. B-series axle's, any combo will work as long as you have axle's for a B-series motor. As far as your wiring harness.........You can run one from a LS integra that's OBD-1. To make it easy just convert the motor to OBD-1 spec, all that you have to do is swap your current distributor for a OBD-1 non-vtec dizzy. As far as the tranny goes, you can use whatever you want but take into consideration that you dont have VTEC so therefor using a VTEC tranny is going to keep you in the top of your RPM band and that is not where your going to see the best/majority of your power. I'd say go with a GSR tranny, I have one and it works very well.

For an ECU get your hands on either a chipped one and have a base map for a PR4 (OBD-1) LS EPROM put on it. The stock values that Honda put on a map for the B20 was never all that good. Or just buy a PR4 ECU and run it till you can have it chipped and tuned.

The BEST/MOST IMPORTANT thing you can do with a B20 is get it properly tuned and have them be a bit "conservative" with it. Do that with your tune and you have a very reliable motor unless you beat the **** out of it and rev it into no man's land for ****'s and giggles.

If I left something out...............Post back and I'll see whatelse I can cover for you.
