fiesta mk4 2.0zetec as follows: -2.0 zetec blacktop engine, running OFAB management. -T4 Turbocharger with front mount intercooler, -Port and polished head, -steel spacer plates to lower compression -Two focus RS head gaskets -Rs turbo gear box, brakes, drive shafts. -Cosworth beige injectors -full decat custom exhaust system, -Walbro Fuel pump -leather recaro seats, Too much to list, to finish this project off, i have been informed that the ecu will need to be mapped in order to run the engine smoothly, as at the minute the Engine is running lumpy as the air/fuel ratio is out of sync. Wht wud the main causes for runing lump i mean worse case wht wid it be or take to run proply cheers if any 1 can help

 

cam timing slightly out casues rough running but your injectors wont be any use on a 2.0zetec turbo so could be running lean on idle, and yes you'll need to get the ecu mapped

 

get it mapped/new management

 

why have you used two head gaskets with spacer plate

 

he should do, it's the same principle as if you were fitting a normal head gasket. To create a seal.

But as above get it remapped. What injectors you using btw?

 

Beiges don't really go too well on a zetec turbo there ok but tend to run lean, I'd take it to a tuner and see what they suggest as they may be able to us your setup and make it run smooth, or recommend good managment/components

 

Wrong chip, wrong injectors

You need a zetec turbo chip and a matched injector too the chip, msd sell these for £250 for the chip, totally wrong ignition and fueling for a zetec when running cvh chips

Just a tip, check out boost monkeys ofam ecu, plug and play with your loom and fully mappable, £389.99, this way you can pick your injector before mapping.


And another, why use spacer plates, when a st170 bottom end and focus rs 1.8mm head gasket with your head and st170 valve springs is proven over 300bhp

Why would you bother?, it's a ticking time bomb at 200bhp, also a t4 turbo is too big for the spec, a t3 from a cosworth would be better

 

It seams pretty thrown together really don't it? It's not a bad setup just needs an expert touch

 

doesnt say its chipped at all as said above its a bit of everything thrown together by the sounds of it. dump the frst ecu and get something modern and mappable

 

Yeh, I would use a stock rst t3 for that spec, with a decent chip/ecu to run it, that way 10psi will be the limit at around 195/200bhp, that way it should be ok

Otherwise I would stick the st170 valve springs and bottom end in
