we have built a 88 prelude for our new ice racer , using b16 pistons , colt cams and some head work , my supplier for headers had told me that pace setter has dropped their line for this car , and im still with out for the weekend , does anyone know if any b series header will work?

What kind of head dose the b20a have on it? I have a b20a3 I'm looking for a head that will fit my a3 with some modification. I'v heard that the a5 will fit so I'm guessing the b20a might fit?

Chikara makes a header for b20a/b21a

Putting an a5 head isnt that easy. When it comes to 3rd gens you have to rewire the whole car, get a fully assembled Si gas tank and run a fuel return line for the PGM-FI system. I probably missed something. it would be best for you to get a Si shell w/ a bad bearing or that threw a rod or some block damage and throw your a3 block on it. (dont boost it tho lol)

I was planning on keeping the car carbed. I might have to make a custom intake manifold if the a5 head wount bolt to the a3 manifold. I woun't have to rewire or put in a new fule pump. do you think this would work?

i dont think the carbs would fit the DOHC head is alot wider. maybe if you get real creative.

If you make a custom manifold, it should work. The B20A5 head will bolt onto the B20A3 block....

Have you tried SS headers? Or I believe they're called "tornado" headers from austrailia.....
