In the making:Headers (pics)

lookin sweet man!

After just finishing custom headers on my cousins 351W Falcon (tight engine bay!), I have two things to add, good luck & keep the band-aids handy!

Nice work!

If you can do some basic weld dont let headers scare you away. Once you decided on the diameter you can either purchase or build flanges and collectors. There are several styles of collectors, some better then others but in a street applications theres is only a couple HP between a standard set and merges sytles.

I found these collectors on ebay, they were going on an aircraft engine but the seller sold the plane. The falnges I made by hand with a grinder and drill press.

that looks sooo clean


nice work


keep us posted one the progress

Looks good but....

1-3/4" primaries??

A bit big, dont-ya-think?

I fabbed a set of headers for my M90 Blown SHO. Somewhat of a waste, no knowing Im going to scrap the car and toss the motor in something else!

I used black pipe and weldable fittings for my headers. No tinny sounding headers here! Inside diameter is 1.25 and use hand fabbed collectors

1 3/4" outside most of the time ends up 1 5/8" ID, still a little big for a NA 3.0 motor unless its forced induction or N20 but it fits the port.

A stepped 1 1/2" to 1 5/8" would be nice but the exhaust port is oval 1 3/4" by 1 1/2". So maybe a transistion from the port to 1 1/2" for about 18" inches then stepped up to a 1 5/8" for another 18" would make a nice set.

The main reason I went to headers in the first place I plan on a 100 HP shot of nitrous

I plan on a 100 HP shot of nitrous

me too

Not a jab, but would suggest you practice welding on some scrap pieces of exhaust tubing before lighting up the final product. It looks like you have both the heat and wire feed set too high for the materials.

Also, based on the heat marks on the ******, you could have some deformation so you should check both flanges with a straight-edge before installing to make sure they are true or get them machined if they're not.

My friend is doing the welding , I'm too much new to do this on my own without any kind of practice. The welds you see there it's because the gases wasnt getting at the tip properly because of a poor connection we made at the assemble of the welder , now it welds like it should. So we were welding without gas on the ones you see on the picture , it's all good now.

Looks real good Phoenix, better than my botch work,

I'm a budget guy so I took my shorty header mine off a 98-99 Mustang 3.8L for my M90 project, the rear one is a stock manifold. It is obvious how much longer the downpipe for BANK 2 is going to be, I'm currently tuning the injectors and tweecer shows that Bank 2 runs lightly richer than Bank 1 (firewall manifold) by about .8-1.0, 14.6 being the goal, although after dial it in more they should both be about the same but my best guess is that a different length downpipe makes some difference, later I will go to a dual 2" all the way back to solve this issue.




Here is a video with manifold's, 2" downpipes to 3" single, no cat, resonator and single blow through Greddy muffler in my Prelude.




After being annoyed by the sound of the exhaust, I put the front shorty header, above, 2 resonators, 2 mufflers off a Corvette C6, no cat, it still has a raspy sound but very quiet under 3000 rpm. I have made a better looking heat shield and wrapped the down pipe to protect the rad and supercharger.

I love how you did improvise when you lack on funds , props on your build man.

 

[SHO_DOODmorrris]

you supercharged that thing... holy balls i though it was just a swap... (by just i mean a shit load of work)

 

[Big D]

Any progress??

 

[Phoenix]

On the headers? they were done a long time ago , they are on the car and it runs as we speak.

Im sorry to thread jack but did this 3.8 shorty header just bolt on? And do you think one would fit on the rear head in a taurus chassis?

 

[Phoenix]

I somewhat missed that post about the 3.8 headers , very cool.

Vid no worky.

No, they didn't bolt on, I cut the 3.8" ******, had an extra 3.0L manifold, welded it's ****** on, the spacing was about 1/4" off but that was easy to fix, for the rear I made my own, it was somewhere in this thread.

I plan to make a new front header one day with equal primaries.

 

[intimdatr]

Thanks for that read! WOW did i learn some stuff!

 

[Shovert]

I thought those look familiar. Same as you. I used 3.8 Mustang one except I modified them for RWD setup. Maurice

[Falconvan]

So the 3.8 headers will fit the 3.2?
