OK i can get my hands on a 87-91 b20a5 powered prelude (whole car) for wicked cheap. My questions are:

1-What would it take to swap this in, and can i use the stock tranny? (and yes i can fab parts if needed)

2-Can you swap other b series parts on to it? like a B18 head? etc...

Any real help would be great thanks...

 

don't get it. this is the bad b series motor. can't interchange most of the parts if any. not the b20b/z you are thinking of

 

i know its not the CRV b20b/z. I figured it might be a ok swap since the whole car running is only 100 bucks. so i would have most of the parts i need for the swap there.

 

That motor is ****, if you want the oldschool B20 get the JDM one from an accord. The north american lude motors are ****. No other B-series parts work with them, they are prone to blowby (ring failure) and burning oil.

Don't waste your time, swap in a teg motor or H22

 

ok just wanted to make sure. i will probably just buy it for a winter car and then ad some no2 to it to watch it blow.

Teg and h22 swaps are way to common for me. i was thinking k20?

 

Prelude B series =

 

If you can weld it in, then do it. Anything has to be better than a CX motor. That B20 has about twice your power.

The B20A5, and especially B21A1 are not as good as the other B series, and all the facts stated about them are true, but it'd be unique. Only thing I can think of is, I believe those Prelude's are cable shifted, instead of rod shifted.

86-89 Accord B20A = 160 HP, but hard to find with a manual tranny, most JDM Accord 2.0Si were auto.

 

it's a waste of time, just save your money and do it right

 

I'd keep the Cx engine because it will actually run for well over 100,000 miles being driven hard, unlike those piles of **** B20A and B21A engines.

88-91 Prelude = total ****

haha when i bought my cx it had 82 thousand origional miles.. after me having it for 4 thousand it started burning massive amounts of oil where the oil light would come on every 4-5 days... and i never over revved it.... dont put the b20 from the prelude in your car its not worth it... if your set just get a 93-00 integra tranny with shift linkage

yeah it has a manual transmission. but as the facts to point out it is a shitty motor for taking the time to do the swap. althou i hardly drive the car. it mainly just goes to shows. But then again the prelude engine would have to be rebuilt seeing that it has over 200,000 miles in her.

well right now the car had over 180,000 BOOSTED miles on it! poor cx motor. but i got spare d series motors and thinking of doing a mini swap for now and then dropping in a DOHC... i was thinking K20 Cuz i was offered one cheap, or a ZC motor just to save money.

 

Actually the Accord B20A is much different than the Prelude B20A5. They share nothing, except name.

Accord = 160, only JDM.
Lude 135.

 

The bottom line is this:

1. B20/B21A engines are piles of ****.

2. Even if I were GIVEN one for free I'd not ruin a Civic chassis trying to make it accept that engine

3. There is little/no aftermarket support foir those engines

4. They are all pre-OBD which means you'll also have to do custom wiring for a shitty engine
