Ths morning i bought a lovely 1.3 fiesta finesse, r reg with 8months mot an tax left on it for a bargin price of £475 has 84k miles.

Wed last week got a 1.6 engine zetec se + gearbox for £325 so im all set to transplant to make a track day car for my other half. Something to keep us busy while we look for our first Cossie

Problem we got are we want to change the cam, i looked at Piper and Kent Cams website for cam profiles which one do i need to get for a prodominantly track usage as several cams are listed on each site which best one to go for i wanting min 160 hp. Please help us pick the correct cam

Thanks Evy & Greenwood

 

Think you may struggle to get min 160bhp out of a 1.6 zetec without spending lots of money

My spec for a 1.8 is:
Kent 1802 cams & vernier pulleys
Ashley 4-2-1 manifold with de-cat
Power boost valve
K&N Induction kit
Banshee induction S/S pipe
Magnex exhaust
2ltr Throttle body
Mapped evolution chip by MSD
And I run it on Shell Optimax

157.9 bhp
120.8 bhp at the wheels
149.5 ft Lb torque

If this is any help my car has since been re mapped by Stu so should see a touch more out of it now as it was running lean.

 

gonna need alot more than a cam for 160bhp.

fast ford did a guide in the latest issue for tuning said engine i think

 

I seen these engines used in Lotus/Cateram 7 replica producing 160-170 hp and appears to be standard apart from cam, exhuast, few bolts and ecu. My other half had been on the phone to a few places an thinks all i need is the correct cam profile and management (i got a chip to hand) need to work out cam profile (nobody will give this away understandable)

Another question if it mapped to 97RON can i occasionally use 95RON what affect on engine it be having? Im concerned about damage, wear an tear as im confident the ecu should retard ignition for lower octane an run little less power which is ok for me is this the case? Or would i need a chip capable of dual maps 95 and 97 to run both fuels if so can you suggest any makes?

 

Shawspeed SS2 or SS1 cams See www.shawspeed.com


Standard engine with rod bolts upgraded on a standard inlet will make 150bhp with the correct ehhaust and exhaust manifolding providing your managment can fuel it properly. make sure you have a good way of setting the valve clearances without shim stacks, ground to fit top hat shims will be best

There are big myths about these engines but they are very tuneable and light and compact. The standard head and valves will flow nearly 200bhp

 

You have a Zetc-E not an SE Different engine

 

I've just noticed that so just ignore me

 

Many thanks Evy showed me an article of them in Total KitCar Mag smone time ago, sounds perfect solution for us

Seems to offer reprofile cam option for £226.78 far cheaper than Piper or Kent cams at £375. On Piper website offers 3 Fast Road cam, Ultimate Road, Rally and Race cam, which is most similar to SS4 from Shawspeed, i would like to see power graph as power band on Piper is high 3000rpm to 7500rpm 8200rpm and 8500rpm. What would these be like to drive normal and in race, I hope these would be reliable in race condition too?

 

I would be wary of too wild a cam, such as Ultimate Race unless the car is ONLY going to be used on track as from what I can gather, it would make it pretty poor to drive on the road.

Sure someone will set me straight if I'm wrong

 

Shawspeed SS2 cams are quite mild and great on the road. I have a set of rpm/bhp/torque figures somehwere for them and they're very very impressive. It's a wildly underated engine by 'home experts' lol

I'd go for new ones ground from blanks tho, not regrinds to keep the original base circle and help minimise the difficulty in sorting the valve clearances. Speak to John tho, he will give you great advice

 

Were trying to keep costs down as were looking for a escort cosworth to buy, do not want that money we put away being eaten up by this car, so a reprofile seems ideal.

Any figures would be a great help in us selecting the cam, power graphs would be ideal that i can visualise.

 

Whats the difference between the Zetec-E and the SE then?

 

The SE is a yamaha derived unit i think. Inlet at the front , exhaust at the rear. so totally different to a Zetec E

 

Ok but sorting the valves can be fiddly and expensive unless you are happy doing that yourself. Have you got the manifold/exhaust as well, cause they'll be a few pounds, Piper do a beautiful system available through PumaBuild
