is there any gains from decating an focus n/a

 

i've got a 2l w reg focus. had milltech cat back on for a while and then bought a focus central 4-2-1 manifold used off a mate that needed a crack welding up. actully it looked like one of the collectors had never been fully welded up

as its a LOT longer than the standard manifold it romeves the cat aswell and i noticed an instant improvement...especially past 4k. i'd kinda got used to the way the car pulled when i booted it before the manifold but after it shot me back into my seat again!!!

personally i wouldnt bother with just a decat as the standard manifold is too short and crap! better off going st170 manifold and cat and flexi as that'll make the best gains and decatting the st doesnt make uch difference if any...although sounds awsome

 

got milltek 4-2-1 and decat on mine massive improvement, as said above 4k rpm the power kicks in. had mine rolling roaded wiv the manifold/decat/custom exhaust andinduction kit went from 113bhp to 144.3bhp. 1.8 zetec btw

 

so the 1800 zetec is only 113bhp?

 

yup or 115bhp depends where u read it m8.
they did a 130bhp spec version for the fezza 1800i slivertop

 

but not in the focus.the fiesta rs1800 your on about,the focus is the blacktop.how much do you rekon you would see from just a decat on its own

 

yup focus is blacktop 113bhp.
5-8bhp gain i would say, milltek's website stats a 12bhp gain on the manifold and decat

 

so you would say 5 to 8bhp with just removing the cat

 

no, 5-8 bhp with milltech's manifold which is a 4-2-1 type and replaces the standard manifold and cat

 

just a guess really m8. makes sense to do the manifold to as the focus has a mani-cat set up. the cat is on the manifold.

 

my 1600 isnt and its seperate

 

i dont know about the 1600 mate but the 1800 and 2l have a supidly short manifod going straight into the cat which sits infront of the block so all perfoemance manifolds (bar the obx shorty which is crap) replace both the oe manifold and cat

 

sorry m8 dnt know bout 1600se engines they are totally different to 1.8 and 2.0

 

i want to get what i can get out of it before i turbo charge it.

 

if your gonna turbo it dont piss money away on na tuning!!!!!!

 

dnt expect alot read this thread all that work for 141bhp https://passionford.com/forum/restor...d-zetec-s.html

turbo'd 1's hardly make to 200bhp,

 

thats a point, no point turboing a 1.6 focus imho. just drop an rs engine in there

 

thats a load of hassle to the engines r mounted the oppisite way round so the mounts dnt match ect, cheaper to buy a 1.8/2.0 and then put the rs lump cheaoer than all the fab work needed.

 

true but still better idea than turboing the 1600 as it'll be cheaper for more power with the rs engine.

tbh, its not that hard. you just need the rs mounts etc. my mate did it to his 1.6 ebony!!

 

black/purple 1 that was in fast ford a little while ago??

the van arken turbo kits make about 150/160bhp on the 1600se, easy get that na out of a 2.0e

 

its alex whitlocks. tis black and was in fast ford. also won a prize at ford fair.

i've got 145-150 out my 2l with full zorst and k&n panel with cold air feed.

 

i did ask this question thou before about fitting a 2litre to replace my 1600 .i asked could replace the engine with the 2litre and just the engine bay loom and ecu and key or do i have to replace the hole entire loom.

 

and u get a decent box on the 2.0, the ib5 on the 1.6/1.8 is shit i killed mine in year only runnin around 160-165bhp. spec is wot i listed above wiv cams and remap.
10k a few track days and rolling roads it went bang. main shaft bearing i think. lol

 

tbh mate i dont know the ins and outs of the conversion. i imagine just engine loom and ecu with mounts and zorst are the major bits

 

alex the kid is his name on here?? nice focus that

 

yep. he's admin on fordtorque.co.uk.

i'm a mod of that club

 

so can i just change the engine bay loom or do i have to change the hole entire loom

 

never been on that site it new??
looks the same lay out as clubcalibra.

 

save ur money build a 2.0 turbo drop that in wiv a stand alone ecu. 2 birds 1 stone. lol

 

the man has a very good point there!
