Just wondering if any Companys have done portwork on IX heads? I would like to see some before/after head flow numbers.

I was wondering this too, especially from AMS, Buschur etc. like their race/stg 3 head work done to the IX head. I haven't heard anything about head work for the IX besides a new one from Kelford or Cosworth at $3300+

anyone know?

 

Cosworth ftw!

 

 

Im glad everyone loves the Cosworth head, it's without a doubt a very nice piece. I'd be proud to run it on my car. However that being said, doesn't mean AMS or Buschur couldn't make one just as good. So I'm looking for some other options.

Anyone have any input?

btw "ifarted" you have "Magnus Intake" listed twice in your list of mods.

You should do your homework on Cosworth... If you did you'd realize why the price tag is soo big. Their experience FAR surpasses AMS and Buschur combined experience. You can't compare them...I'm sorry its just not fair.

 

i agree 100%

 

If you read my post I aknowledged the Cosworth head is without a doubt very, very good. That's not my point, I'm just looking for other options. The Cosworth head is accually not a bad price considering it comes with a complete valvetrain, and theres no core charge. BUT it's still a lot of money. It would be nice to see some bench flow numbers between the AMS, Buschur, Cosworth, and Kelford head all things being equal except the head itself. Doubt it will happen, but it would be nice.. maybe I'll just break down and get the Cosworth head, I'm gonna be using their cams anyway..

anyone else?

 

If you call cosworth Im sure they'll give you flow numbers of your cylinder head. check out Jackson Auto Machine. (JAM) see what they give you....might be worth your time IDK.

 

Just because something is expensive doesn't make it good. I have seen this head in person and its not anything special. The cnc ports look nifty. But after they machine the ports they reinstall new guides that are huge. No attempt at streamlining the guide. They have loads of good experience modifying fords but virtually none modifying 4g63s. I have seen the AMS head and would go with that hands down. AMS has tested many different heads from different porters to find what works best. All cosworth has done is use their name to sell overpriced parts. 1100 for pistons, 3000 for a crank, 3500 for a head. Give me a fooking break.

a fool and his money are soon parted.

 

You're right. What do they know. I'm a fool. What fast car have they ever built? Its not like they built their whole business off of one car.

Showing some 4g63 experience would be helpful. Posting what we already know is not. Specializing in one platform goes way farther in the tech deptment in my book. I have 7 years experience making 4g63s run well. people ask me all the time to help with other platforms. Nissan, Toyota, Subaru, mustangs, supras. The answer is usually no. There is some general knowlegde of performance that transfers form car to car. But the stuff that really makes the platform shine is the stuff you learn from modifiying the same platform over and over.

I will take a pic and show you their lousy valve guide choice.

 

The cosworth cams vs GSC cams( for evo 9) may be a good example of cosworth foot in this game. Everyone who has installed the the cosworth cams has posted how the car looses torque down low. Some have even admitted for a daily driver the cams may not be the best choice since so much drivabilty is lost. Then look at gsc cam test report with dyno plots to back it up. NO LOSS of low end torque or drivabilty with same increases after 6k rpm.

Cosworth= using great name to sell parts that work okay.
GSC= specialist in 4g63= more concern for actually selling a cam that is gonna work best in the 4g63.

 

Because Ford no longer writes the big checks for them and they are forced to enter in to new markets. The work is overpriced in my opinion because they have such a heafty overhead.
