i am currently sourcing parts for my mk6 4x4 cosworth fiesta and need to know what bits to source as the base of my engine build, will speak to tommy at fms but hes not about at the mo so thought id ask here,

power aim will be 450 - 500bhp approx

obviously its going to be 4wd but what parts are the better to use???

2wd head or 4wd head

ideally a 200 block

2wd or 4wd zorst manifolds

anything else different?

thanks
marc

 

i believe the 2wd manifold is better for high power.

I have a 200 block, new ground crank, 2wd head, 2wd manifold should you want them.

 

going for the same power mk in me cossie rst ,

ive a 200 block , unground crank , 2wd head , and 2wd inlet ,

iirc thats the best combo ,


hows it coming along fella

 

how much for the block and head and manifold? is the block and head bare? and when you say manifold do you mean zorst or inlet?

cheers mate, well i am starting from scratch so just stripping down the 53 plate diesel donor car i got, and currently phoning around for quotes to do the shell fab to accept the 4x4 running gear etc,

gonna be a while yet but i love it already,

just need somebody to buy my m3 to release funds for this

 

 

now ive heard people say the 4x4 head is better to use lol

and i still have spoke to my engine builder yet to ask him,

im starting to think it differs between engine builders personal preferance

 

surely 4x4 inlet flows better then the 2wd one!

 

not talking about inlets mate as il prob use a rainbird swedish style inlet,

just on about the better head

 

the best of the components of the 2 engines

200 block (non turkish)
4x4 head
2wd exhaust manifold
4x4 inlet manifold

no need for a sweedish inlet at that power level, a 4x4 inlet with a 10mm space will be fine (NMS doesnt even like sweedish inlets!)

the head will probably need porting tho

 

i believe the 4x4 head is the one to use. It has a better cooling jacket and bigger exh manifold gasket face.
