does anyone know if it is hard to swap a b20b into a 1990 integra with a gsr tran any answers would be helpful

 

shouldn't be any harder than any other b series. one thing though your 90 integra is non-obd (obd-0) and i believe the b20b is obd-1 so you will need the wiring harness from the b20b or a conversion harness

 

dont get a b20b get a b20z....the best of the crv engines

 

not at all you could use the same mounts as your teg

 

ya but what about shift likage if im using a gsr tran what would fit right and is there anything else i should be ready to do or buy

 

isnt the b20z set up for Honda's wanna be awd? (front wheel except for when they start to slip the rear compensates, therefore not that worth it anyways?)

correct me if im wrong

 

the B20 motors were in the '97 and newer CRVs. so correct me if I'm wrong, but B20s would actually be OBD2, based upon honda's obd years.

and the B20Z is no different than a B20B, its just that a B20Z has a higher compression, and therefore more horsepower. thats no big deal if you plan on changing out pistons, and it's actually better if you're committing the unspeakable act of turbocharging a stock motor.

B20's also came in older JDM (and US?) Preludes. I don't know which came in which, but I think the higher compression one is the JDM Prelude engine.

depends on what ur lookin for if u want all motor get the b20z b/c it has high comp ratio if u wanna turbo stay with the b20b unless it dont mattr and ur gonna rip apart evything

 

On that note, if you're prepping for FI you'd be better off to resleeve a B18B1. The B20 sleeves aren't very strong. The outer blocks are identical to each other. Plus, the B18B head flows much better than the B20's.

As far as the tranny question. Afaik, B-series trannies and blocks will all bolt up to each other. Not all internal parts are interchangable, and I don't know what it takes to swap cable/hydraulic, but they will at least bolt together.

That was the B20a and B21.

 

I just got my B20B in and was talking to the guys over at hmotorsonline.com and all b20s are obd2. And to put a b20b in your integra, which I am..you have to change out the intake maniold (because it f*ckng huge) and thats about it...as long as you still have all your stock parts from your previous motor...like dist, starter, flywheel, clutch, alt and etc, it should be a good swap..thats just what I have found. Also its hard as hell to find a B20Z..thats why I gave up and went with a b20b

 

I'm not certain but I think the B20 and B18B heads flow the same. I've heard the B20Z intake cam has 3mm more of lift tho.
