3B Headers

J's40 · 02-26-07, 09:46 PM

I have a 3b that I'am going to put in my 72 fj, but it needs new headers. What do ya'll think is the best place to purchase these from?

cody c · 02-26-07, 09:50 PM

umm? why not throw a turbo on it instead of gettin one custom made and turboing later, as far as i know there is no off the shelf header for a 3b except a 13bt or 3bt manifold which is made for a turbo.

When I bought it, the guy sold me a turbo with it. The headers that are on it are really rusty and I think it really needs some that are in better condition.

Can you post a picture of it?

Does it fit a turbo now? Is it a turbo manifold you are after or "edelbrock" type headers? If it's "headers" you are after you might have a hard time finding them. If you want a stock naturally aspirated manifold there are many out there. Post in the wanted diesel parts section.

Cheers.

My 3B has Motovator headers from AUS on it!

My engine is at a friends shop. I'll try to post some pics of it this week.

Search Roberto "threads" and you can see his Bj42 with the strange headers. Look interesting! But I would rather a turbo.

Roberto · 02-28-07, 08:53 PM

My 83 BJ42 I bought has Motavotor headers on it, but dont anything about them except someone from the forum has them on his also and gave me their website which is:

I know this is a little off topic, but does any one have a recommendation for a muffler to quiet this beast down. I plan to do a full "sound proofing" this summer, but it would be nice to be able to pull into a drive through (once a year) and talk without killing the engine.

The header listed above isn't at a bad price... improve air flow with a header, maybe replace the cat. with a NOx scrubber and add a big fat muffler and get no net change in back pressure? The ideal, of course, would be to have a net improvement in flow...

Eric Winkworth · 03-03-07, 11:54 AM

it is a pita shutting it down for a second, and if you have a turbo you have to time it down...

I would think the motor alone would make enough engine noise so the person couldn't hear you.

brownbear · 03-03-07, 07:22 PM

Most of the noise is from the engine IMOP. A decent sound proofing on the hood will help.

I just had a new resonator installed prior to my muffler on my diesel Mercedes, replaced the pipes with holes, and it is hugely quieter.

With out a turbo, shutting down for second or two is no biggie. With a turbo, if you sitting at TH the wait is long enough with 20 cars in front of you that the turbo will be cool enough to not care.

ylexot · 03-06-07, 03:00 PM

I'm definitely going to do as thorough of sound proofing as I can: cabin as well as engine compartment. I expect that will help a lot. Still want quieter exhaust so the people waiting for bus stop looking disappointed when I come over the hill.

I've seen where to place a EGT sensor on the exhaust manifold. Where would I put it if I go with headers?

Yeah.. It's called a turbo. With one of those installed, the motor will PUUUURRRRR

ylexot · 03-07-07, 12:35 AM

Hmm... you're starting to convince me. More power and quieter? it's hard to beat that.

Anyone have a good (read inexpensive) source for a quality turbo?

i've been told junkyards are the place to look.

I've been thinking about it too but I think I'd have to get a special manifold. I have a 3BII and I'm not sure if flipping the manifold will fit underneath the hood, without complex tubing and whatnot
