The factory manifold is also a cast iron piece with shorter runner lengths and thicker walls. You get a lot more expansion out of a stainless tubular manifold for several reasons.

1. Stainless expands a lot more then cast iron.
2. Longer runners mean more material to expand, thus a larger amount of expansion takes place.
3. Thin wall manifolds tend to reach a higher temperature in the metal because of a lower thermal mass. The higher temperature means lower metal strength and more thermal expansion.

If you restrict the movement induced by thermal expansion, you will crack something. You can build up a TON of stress due to thermal expansion.

If you don't isolate the exhaust movement from the manifold, you will cause cracking as well. Thus the reason for the flex coupling on the stock exhaust.

though, don't get me wrong, build looks bad ***.

 

Binary i started mine for the first time today! Thanks for inspiration!

 

^^^ Son of a B! You beat me to it!

 

Heh... well i didn't have as much work to do. Stock turbo and all that.

Just drove it down the street for the first time. Threw P0030 right off the bat. Guess i'll be keeping my scanner in the car and waiting for those ECU Flash guys to figure something out


wow... just a couple weeks ago!

I got the wastegate and boost control all plumbed last night. Check that off the list.

I also refilled the transmission with oil. Check.

I had to trim my center bumper cover support for it to go over the IC. This is the strip of metal that runs across the inside of the bumper cover, it hit on the edges of the IC. I didn't recall that being the deal on Buschur IC's but I had to do it. I might go in and strength what i had to cutout, it made the support MUCH weaker.



Tonight I should be able to swap out my race wheels and tires for the all-seasons, install the wideband, fill the transfer case, mount the fan control and build the extension tube for the upper radiator hose. I'm trying to finish all the little stuff so that on Saturday I can focus on the O2 housing, and dump tube the two required items outstanding for startup. I'd also like to do the catch can and new brake ducting while I'm fabricating, but only if I have time.

 

Do work son!

 

i love the manifold

 

Well I did get some stuff done last night. I got the fan controller mounted to the frame under my airbox. I used some sheet metal screws and some red loctite. Then I cut the extension tube for the upper radiator hose, I used 1.5" SS tubing.

I also made the first cut on the tubing that will be used for the O2 housing, and did a little test fit. It's going to be TIGHT! I spent 30 mins staring and thinking

Tonight I'm thinking I'll swap out the wheels, adjust the ride height and refill the transfer case. Then it will be go time for the O2 housing come Saturday. I'm getting excited to start this thing.

 

Epic Build.

Amazing Build thread man Now I just cant wait to see what she car do Keep up the good work man...

 

this is an amazing write up i just spent an hr just looking over all the pages. keep us posted awesome engine for us military guys.

 

consider my double post an epic bump.

 

On an engine break in I thought you were suppose to use non synthetic oil?

 

He put in non synthetic.
