Is it really worth it to buy the cosworth mivec head, or will building my head myself (using my machinist) be the same? i need feedback guys

 

cosworth is very overpriced. there are plenty of other good options like buschur, ams, gsc, maperformance, english racing, etc. i had headgames do mine.

yea its pretty expensive but its great quality, not saying that other companies cant do the same, also cosworth is giving you a brand new head thats why its so much more, But thanks, I'll look into it, i heard lots of good things about headgames

 

rebuilding a head has advantages and disadvantages. yea with cosworth you know what your getting top of the line pretty much. From my experience rebuilding a head with a solid usable core will def be up to par with some of the other options such as ams, buschur etc. depending on how experienced the machinist is and the selection of vavletrain that goes into the head (springs, retainers, guides, valves) Price wise it will probably save you money to rebuild your own head, with some very good results. Ive built a couple 4g63 motors and ive always rebuilt the head and have had no issues running some good power and high rpms.

 

its really not worth it. their good products and perform well, but there is no need for a brand new core and other companies have proven to make more power.

 

thanks alot guys, i might just send my head to bushcur or headgames, im probably going with kelford cams and beehive spring and retainers i just want to have the ultimate head <- that sounds a bit funnnnyy lol

 

u cant go wrong with that! but i would recommend GSC S2 cams instead. their proven to make more power.

 

i have a set of S2s i must say best all around cam for almost every application. I made good power with them. definitely recommend.

 

really? gsc over kelford?

 

just custom build urs at a machine shop, just make sure they follow spec standards, balance, etc

 

yea my machinist is really good, ive seen alot of his evo motors, Hes doing my bottom end, i held off on doing the head with him, not saying hes not capable of doing it, i just want to see other options out there lol i try to be a perfectionist, it kills my pockets, but at least i know everything is perfect

 

alot of people think that headwork is all the same, the truth is just a good valve job can make 10-15 hp easily

 

yep. better CURRENT profiles and no false knock issues.

 

their both good cams, but ive seen/read more gains and better driveability with GSC cams.

 

i'll definately look into it, what spring and retainers though?
