Hi,

what compression ratio will a std 1.8 Zetec bottom, with a RST ford H/G, and a std RST head be running,


also what power can std rods, and rod bolts be able to run safely?


Cheers Danny

 

Here you go mate work it out for yourself,- www.turbofast.com.au/Tfcomp.html

 

Cheers mate,


but i know how to work it out,


but i need the

bore size,
Stroke,
Head and H/G capacity??

 

If you bolt the standard head down to the 1.8 zetec bottom end you will get 8.5:1

 

Cheers Jonny,

is that using a Ford RST H/G?

Which head bolts are used?

 

any info welcome.

 

Why not just go zetec?

 

its not for me,

and he's budget is real tight, so its either a a std rst rebuild, or a zvh.


its all on a xr2tt, so the powers limited to what parts he alread has on his car.

 

A standard ZETEC will make as much power as a standard RST. No turbo lag, better fuel economy, better response etc.

 

i know what Zetec's can do,

But he's car is a turbo car, and thats the way he wants it. and its not std
I said a std rst engine, not power.

 

Ford head gasket and bolts

 

What head bolts tho,


as std cvh ones are too short.

 

You either need to mill the head bolt platforms down to get the correct thread engagement which obviously then leaves the head only suitable for zvh's or I have used a head bolt set from a 6 clyinder bmw engine witha female torque head. Unfortunately I cant remember what car it was exactly but you could look up and compare in head bolt book perhaps.

 

Cheers mate,


i'll try and get longer bolts from a bmw.

 

Found these mate dont know if there any good, Also they meed to be around 150mm long and 12.9 spec if that means anything to you.
