FJ40 Exhaust Header? (3 Viewers)

[FloridaLife]

20 years ago I was rebuilding a 1934 Dodge Coupe and found a 1958 Chrysler Fire Power Big Block Hemi in a junk yard, bought it, and then had a friend balance and blueprint it. I was surprised I could do it, but I also ordered a pair of Sanderson Jet Hot Coated (aluminized ceramic) headers that they guaranteed to get you 30 more horsepower on the dyno WHILE ALSO reducing the temperature in your engine compartment 20 degrees.

I did a quick / search and haven't found anything. Does anyone know if a header made for the 1978 Toyota 2F engines?

Thank you!

I have a man-a-fre set. I made my own brass stepped washers to compensate for the thickness difference between the aluminum intake and the steel header +1/4". I made new longer "studs" to handle the extra thickness. I planed the header and the intake on big piece of glass to flatten them.

I soaked 2 man-a-fre gaskets in warm water for about 1/2 hour and then installed the system with high temp anti-seize and stainless steel nuts. After a good warm up I retorqued them. The system has never leaked. Oh and I notched the air cleaner bracket to make it easier to torque the nut under it.

This header and gaskets has been on at least 2 engines, maybe 3 since the mid 80's.

I also made a fluid heat riser for the bottom of the intake, without it the carburetor ice can form choking the engine, and you have to pull over and wait for it melt. Hasn't happened since I installed the fluid heat riser.

In some previous post I had a pic of the air cleaner notch, and the step washer.

A header and exhaust made a noticeable difference on my F engine, but it certainly wasn't anything like 30hp! Maybe 5-10.

I would think one of the biggest advantages of an aluminized ceramic header would be the reduction of heat in the engine compartment.

Never saw a true advantage to headers after driven both for 10-15 hours straight from Montana to Mexico….three times….floor is significantly hotter so make sure you ceramic coat otherwise I wouldn’t waste my time.

Unless you don’t have stock manifold then sure I suppose, I still go back to stock.

Good to know. Thank you.

I’ll 2nd the heat conversation on the headers. It’s on my list to go back to OEM …. Down the line.

What’s on the truck now?

Good question. I'm guessing the factory exhaust manifold. The drivetrain is shrink wrapped on a pallet at the mechanic's shop or I'd go out and look.

 

[igotta40]

In that case my advice, and probably speaking for others, don’t put a header on it.

I'm convinced. Thanks!
