In the process of making my own inlet manifold, will be using the st170 manifold for the injectors, just need a few more bits and ready to start welding, will hopefully be able to use a standard idle control valve with it and will have all connections for the vac hoses.

 

Will stainless steel not get to hot for inlet manifold?

 

Should be fine, if people are willing to run 'phatt' cone air filters next to exhaust manifolds im sure stainless steel will be fine

 

Is the car na or turbo'd ?

 

It will be a zetec turbo when its all built , and to help with heat protect i plan to get it ceramic coated.

 

Why not just build it in alloy

 

That's a good question, stainless is easily available to me through work as we don't use much aluminium. Might make another one some day and will try ally next time

 

I wouldn't be using an ST170 lower inlet on a normal Zetec

 

Whys that man? Plenty of people have done it :/

 

IIRC the port spacings are completely different, I'll try and get a picture to confirm for you tomorrow as it's been years since I've looked at Zetec engine bits

 

Oh, I'd be very surprised if that is the case as many people have used them without issue. A picture would be great, thank you.

 

Finally got round to taking the picture



Not as big a difference as I can remember but as you can see the ST170 port sits higher in the head as well as being bigger

 

Ah well I can't see it being unusable and making any difference at all, I'm going to be porting my head and will be useing a dremel to port the st170 inlet manifold and will do my best to line them up, thanks for taking the time to tke the picture mate, cheers
