Recently baught and restored a fiesta rs1800

It's currently standard but from a few upgrades of aftermarket fuel pressure regulator and it's running high lift cams

I'm wondering about what else I can do to squeeze more out of it without pushing the engine too far

I am pricing and going to get a custom exhaust built and fitted any other ideas of what I can do or what people have done would be great

 

Great looking car. I had mine resprayed 18 months ago and just love it. Fun little cars.

i haven’t looked at any upgrades to mine as I’m trying to keep it original.

 

Yeah love the thing I have to fit a new cat and send it for last but of welding then its will pass the mot I had.one done to see what it was failing on about 2 weeks ago

I want to add a turbo to the engine because it will be so much fun but that's this winter's job for this summer its gunna he run as is and aesthetically tidyd up it's on high lift cams but I want to pull more.out of it

 

As you're planning to turbocharge the (is it a real one?) RS1800 next winter, why do you want to bother tinkering around with the N/A engine for just a few months?

 

I'm wanting to upgrade the engine starting work end of this year just wanted to know what people have done or what I can do and what extra Bhp I can get

And yeah it's a real rs1800

 

I had a budget built 1.8 zetec turbo in my MK2 fiesta after my frst cvh melted. Was planning a zvh but ended up going full ZT.
this was 20 years ago now, and all i will say is do it properly first time. Things have have come a long way since then.

Tbh I would look into a focus RS swap and keep the 1.8 original to go back in the car if you ever decide to sell it

 

yeah seems like that may be better few have said what is done if i change the throttle body upgrade that i can get 150-180bhp from the engine ive got some bits to do on it but later this year i am taking the block out and getting a respray and just genrall tidy and clean up in the engine bay

 

150-180 bhp on a N/A 1.8 Zetec with a "throttle body upgrade"???

 

what I've been reading into I was a bit suprised but suppose if people have done it then cant see why not alot of stories out their how much is true is another questio

 

Most of the standard 1,8 engines struggle to produce their claimed outpot of 130 hp. So with a manifold, chipping and perhaps a different throttle body you might get your original power back. Keep it as it is and concentrate on the turbo conversion.
