Hmmmm - Not good...
money is not really an issue but if it does not make a great difference with the evogreen turbo then I will not bother.
However, like most cars when changing headers, if they really do make a difference then I will get it.
Just confused - want to make sure it is worthwhile upgrade.
Does it make any difference is noise?

one thing about headers is CARB cert.
The stocker is carb certified, so in states where you can get a ref ticket (CA)...porting is your best bet.
Tubular headers are great for race prepared cars. Not really DD...
A tubular header, no matter how great the welding, will eventually crack, and need to be re-welded. no problem if youre on a race team...maybe a problem if youre sponsered by your pocketbook.
cost to benefit fo rth estocker outweighs the tubular mani... wait to get a 35r...then buy the manifold.

I have the Full Race manifold with my FP Green but I really can't give a fair comparison against the stocker since I installed the Full Race manifold together with my FP Green. I remember David Buschur doing a test on the Full Race manifold along with other manifolds but I can't remember how high the boost was when he tested these. I run 28psi on my EVO so at these boost levels i'm not sure if the Full Race has a greater advantage over the stock cast piece.
As stated by others, if money is not a problem at the moment, go for the Full Race, it's been proven to work so you don't have to have any doubts of it not working or being a downgrade. Good Luck!

My only concern with a full race or tubular manifolds is cracking. Apparently they all do at some point or another. I know some are going to say it has never happened to them and it may not, but it is just a risk IMO. To me, I rather stick with the iron stock manifold and get it ported. Buschur does a port and jet coating for the stock one for about $200. I'll take a little power for reliability.

Take a look at this thread as well...

For some reason, there are always those which simply do not appreciate quality craftsmanship to the degree that it is due.

EDIT: I have sent an e-mail to Geoff, he is out of the office until Nov. 6th but I will post his reply when received.

How do your dyno numbers compare to those of FP Green turbo motors with the stock cast iron manifold?

In the end, I think people will be fine with the stock cast piece but if it really bothers someone and they feel they need the Full Race manifold and money is not an issue then they should go ahead and get the manifold; it will perform.

BR did a back-to-back dyno comparison on the stock manifold; his p/p manifold and the Full-Race manifold. The FR manifold made more power but not much. I think the thread was back in 2005.
I would suggest getting the Hotside ported/polished/coated as well.
I have a BR ported/polished/coated manifold sitting in my garage right now.

Like I said, I have a BR manifold sitting in my garage and have my hotside on it's way to BR in the morning. I'll be connecting it to a Green soon enough. Wish I had a FR tubular manifold to compare.

I haven't really done a comparison between people with the Full Race manifold and those with the cast iron piece. I rather not look at dyno numbers because I feel that this is an invalid comparison as dynos read differently. The best I can do is observe my track times and compare that to others. This past weekend I ran a 11.65@116mphl; this was done with 387hp and 385 tq on a local dyno when I was tuned.
In the end, I think people will be fine with the stock cast piece but if it really bothers someone and they feel they need the Full Race manifold and money is not an issue then they should go ahead and get the manifold; it will perform.

I agree with you, and thank you for adding to my comment regarding the sometimes unreliability of dyno testing as a tool for comparison. Congrats on your quarter mile times, that is impressive.
I commented about this test in my above post, but thanks for the heads-up. The main reason I disagree with some of the information posted here is the fact that (according to the dyno I was tested on) I have seen significant power increases with just a few minor modifications and I attribute some of that success to the Full-Race manifold. For those members who have not seen the results on a first-person basis, the dyno testing performed by Buschur has become the sole source of knowledge regarding manifold comparison. May I remind all of you that the tests were performed by Buschur Racing, the same company providing (and profiting from) the services of porting and coating the stock cast iron manifold.

Would love for someone to do some more testing, but still don't think $1000 is worth a few extra ponies
