Hi, currently lookin at building a zetec turbo engine, done some research on here so think I kno what I'm doin!! He says!

Jus a couple of questions I'm hopin for help with -

Got a 2 litre silvertop bottom end, but I've read the blacktop head is better for flow and has solid lifters etc, will a blacktop head fit on a silvertop bottom end?

And lastly are all 2.0 blacktop heads the same? ie focus, mondeo or whatever?

Any help!!

 

53 people looked at this an not a single response!

Thanks!

 

as far as i know the heads are all the same except focus rs and should fit on your bottom end

 

Was gonna stay away from focus rs an st170 heads, but dont wanna buy a blacktop head to find it doesnt fit tho an then ave to buy another one! I always do things the long expensive way an thought someone on ere could point me in the right direction!

Thanks for your help!

 

You can bolt the head on but the pully and tensioner setup are different so wont be a straight fit.

 

Just buy a complete engine. The silvertop no doubt bolts near enough straiht in im assuming and the black top doesnt, and so depending on your power output the silver top may be fine. The black top is a better engine though!

 

I would usually! But I've already bought a brand new silvertop bottom end complete, an would rather use this now! Think i'm gonna stick to a silvertop head now anyway, I'm only lookin for approx 300bhp an I think I've read that a silvertop head will do this easy so might as well!

cheers

 

Stock bottom end will not reliably take 300bhp, maybe 250bhp.

 

Got forged rods an pistons!
