Im posting this for a friend who just bought a fiesta rs1800.
He basically wants to know approx what power could you expect from the following mods
- race spec cams(he doesnt know which ones yet)
- head ported and polished
- Forged pistons
- bigger injectors
- (Maybe upgrading the turbo)

He has great intention of modifying this car and just wants to know what kind of power to expect from it afterwards

Thanks

 

RS 1800s Dont come with a turbo, rs turbo's do, Standard rs1800's are meant to be 130ps which is about 128 bhp I think,
If he changed the cams and head work I reckon it would go to about 145 150 bhp

 

Most of the Zetecs, especially the 130 PS 1.8 didn't throw out the whole power as claimed...

So hope the engine is more than just a few hp above "standard" power.

 

There is no point fitting cams, or valves or anything unless you change the inlet manifold. That is the most limiting part of the engine.

 

What would you use instead?

 

It must be an RS turbo he has so...or else it had an engine transplant at some stage. Any thoughts on modifying the turbo engine?

 

Fit a megasquirt and either a rover turbo inlet or motorbike TBs. Should see 150ish bhp

 

are these angines very tunable? im thinking of getting one but im just woundering how easy is it to get one to about 160bhp ish, how reliable are they and how much is a good condition one worth? also how much do they weigh?
im talking about the rs1800 by the way not the rst
cheers

160 bhp is easy if done properly and up to 200 bhp the ZETEC is very tuneable and very relaibale.
