We are lookin to upgrade the g/f's Fezzy Zetec S..

I was thinking first off, a new chip and a set of uprated cams.

Has anyone had any experience with these ??

Any advice woudl be good

Al........

 

No point with cams unless you get a 4-2-1 manifold and decent exhaust......with the right cams and a remap ( not a chip IMO ) should see 140bhp+

 

by the time you get a set of cams some headwork and a remap you could almost have done a low pressure turbo conversion on it.

n/a tuning sucks arse

 

lol it does, I see superchips do one, but only gives 7bhp

 

total waste of time really mate

spend a grand to see 10% more power and 5% more torque

spend not much more turboing it to see 30% more power and 30% more torque "ish"

 

Great engine to turbo with an 11.1 compression ratio and weak piston rings/oils controll rings ..... ask Van Aaken how reliable they are

 

Easy enough to change the pistons, secondhand vauxhall ones can be made to fit and go for peanuts with a new set of rings available for 50 quid or so.

Or failing that a thicker head gasket for less than 100 quid sorts the problem with CR out and the pistons are going to be strong enough to handle moderate boost once the CR is lowered as peak cylinder pressures neednt be much higher than the were to start with

 

Which vaux pistons could be adapted for the Zetec-SE engine? Always thought about turbo conversion but custom pistons are too much

 

Spot on. There's no go with out blow.

However the vx pistons won't fit in this engine. It is the zetec se and is totally different to PROPER zetec engines

 

oops, apologies, total for me on the pistons, i didnt read the post properly and was talking about a proper zetec engine


You will still get away with moderate boost on a thicker gasket though

 

Yup i reckon you could probably runner thicker gasket and nearly and 10/12 psi though there.

If you want cheap tuning, why not give it a sniff of gas?

 

The Zetec-SE is MUCH better to n/a tune than a 'proper' zetec

 

Well if you mean on the standard bottom end then you are lmistaken about those pistons and rings being so weak

 

Cause its not cheap on a daily basis.

IMHO nitrous is only any good for making a fast car very fast, not for making a slow car fast.

You would be driving on gas the whole time, and at a fiver a pound or so thats VERY expensive in the long run.

 

see http://www.shawspeed.com/fsigma.htm


here is a brief description of a friends Zetec-SE currently being finished


"...6500rpm where it's producing a shade over 230bhp and 187.5lb/ft of torque. The torque before this is also impressive as it is making 160lb/ft steadily between about 3500rpm-5500rpm ish so should be very driveable.
Probably won't make any more torque but should get +250bhp...."

 

Matt, impressive stuff but of little relevance to a standard engine.

Look at thier prices for even the more basic upgrades and you can see the amount of work involved:

210bhp Kit Ł4390.76 inc. VAT



For that 4 grand, garage19 could build you a monster of a turbo engine i suspect

 

I was just pointing out that it's a good engine to tune not a poorer cousin of the 'proper' zetec. Not too fussed about the money discussion. It's light, all alloy, a good 16v head and very tunable.....I believe westfield ( or caterham ) have recently announced it in their new lineup.

I think to be honest a 110% increase in power for around Ł5k is a bargain

Cant do that to a cossie

I've seen plenty of theses turbo'd as well but not a reliable one for less than Ł5k ..theres better engines to turbo

 

Too right! The problem with n/a tuning is that it is soooo expensive for what you get. And with all those revs that you will need probably less reliable/ not as long lasting as a forced induction engine.

At the end of the day its is your missus car, so put a new exhaust trim on, tell her its gained 20 bhp and she will tell you how much faster it feels!

 

Ł5k on a n/a cossie will see you at 250bhp.. another grand should see you nearer 280bhp (touring car spec)..

 

He meant you cant get a 110% increase for 5 grand.

Although obviously you can, easily, lol

 

cor, you dont know his mrs very well

she would be more likely to tell him to ditch the chavvy crap

 

I put a chavy clamp on exhaust trim on my missus truck the other day while i was sevicing it. Went down a storm with her horsey crowd before she noticed!

Truck was the only thing i got to service that day
