well, I havn't been around for about a year.... lots of stuff goin on.... but anyways, i got some new found free time, and a little cash burning a hole i my pocket.

I found a B20A5 ater my research this is what I have came up with.

The motor is NOT vtec, and uses ODB-0 so I should have minimal wiring issues with a ECU swap???

The motor is basicly the same as a B16?

So, Hasport mounts and axes will be equired with a swap out to an integra front hubs.

What eles is there? Has anyone got pics of one done before? Or even a B swap?


Thing is I can get all the JY parts "motor, tranny, front end, wires ECU... the whole shabang" for like 350$ And even If I have to buy the hasport stuff NEW I am still looking less than a grand.... minus the rebuild parts, For I would be completly tearing the motor down and the tranny I will be taking in to get rebuilt.

So, Any other BIG surprises I should be thinking / worried about...?????

Thanks guys.

Well, after more searching, I belive that I am ok.... but I would still like pics....

The B20 series was more of a torque engine than a hig rpm power engine but a lot more engine of any type will make a old Honda move pretty good. You can make anything fit (with a large enough hammer), check with HASport to see if their mounts will work on the B20 block. You will also want the axles and the wiring harness from the donor car.

Let us know how it turns out.

Lets see a project thread or something made out of this...thatd be neat

The B20A i think is from the 88-91 Prelude IIRC. And the mounts for the 3gen Preludes are different that of the B16, B18, and B20B.

The B20A, and B21 are what everybody calls "Bastard B-series" because they have little to none in common with the other Bseries.

yep what he said ^... The regular B series mounts will not work with these engines.

That and theres little to no aftermarket support for them. You dont want it anything with B20 on it from honda, even the regular ones.

I'll admit though, these B20s are much better than the CRV B20s but are still just as useless unfortunatly.

The B20B and B20Z's from the CRV's and other assorted JDM cars, are great motors.

They might not take alot of abuse or boost, but if you drive them like they were ment to they do amazing. The B20Z from the Later 1gen CRV's with only a header makes a ton of power and torque. Honda underated them and stuck a horrible exhaust manifold on them because they didnt want there SUV to make more power than there Sporty Civic or Integra's. I cant find it now, but i saw a build just the other day, a guy is building a H2 car, its a 90-91 Hatch with a B20, he has a CAI, Header and exahust, and dynoed somewhere around 150whp and 160wtq, With the 8.8:1 JDM B20B, not even the 9.6:1 B20Z.

Don't be too quick to throw the idea away.

One of my other cars is a gen 3 prelude with the JDM B20A6 series - very similar to the B20A5. The motor is good in my opinion if you use it for what its designed for - nice and flexible, pulls from low revs, just doesn't want to rev. If you want something that will cruise rather than race, it would be a viable option. I am thinking of putting a H22A in the lude and moving the B20A6 into a gen 1. Only real problem is that it's done 380,000 kms.

Another motor in this series - the B20A - is the jdm accord series 3 motor - that has 160 hp and 140 lb torque. (The B20A6 has about 140 hp). An interesting feature of the engine is that it apparently has no overlap between the intake and exhaust cycles on the cam. So the Accord guys are using cam gears to create some - they move the intake +4 degrees and the exhaust - 4 degrees, and still don't get much overlap. The hard core guys look at about +8 and -5 - after that the valves hit each other. The engine is also closed deck. While there are no aftermarket pieces designed for the motor, there is some interchangeability. Boost seems to be the preferred route.

One guy there was doing b16 heads on this block. That required custom copper head gaskets, among other things, and needed a cam change to work properly.

Anyhow, check out http://www.3geez.com/ for discussion on this motor series etc if you are serious about looking at this motor.

I know they are fairly good motors, just i wished they shared more with the other Bseries.
