i am wanting to put a puma engine and gearbox into my focus as done in the zetec sport, can i do this. just everything looks alike but just want to verify
thanks and any help appreciated

it can probably be done, wiring will be fun but doable.

But why? for 123 bhp?

for less money you could drop in a 2.0 blacktop zetec.

will need the ecu,wiring loom and engine mounting i think. but why? your only gaining 25hp at best, if your going to swap engines why not go straight for a 2 litre? beat me to it.lol

plus considering the price of good low mileage puma lumps and st170 lumps you might not have to spend much more to get 170bhp

because if it is as simple as doing it to the zetec sport, swapping engine mounts, engine and ecu then its simple, than if i have an st170, suspension has to be done, brakes have to be done, was going to get better brakes anyway but want to put it back to standard without much trouble...just want that little bit more power, only being 19 i think st170 bit to much to be honest aswell. 25 hp is enough for me.
thanks guys

youve got other issues to consider, the pats system and alarm system changed on later mk1 focus as it did on late pumas so you need to match up the right age of ecu to your car.
Also be aware that your dashboard is likely to take its speedo and rpm feed direct from the ECU via a databus which early puma ecus dont support. Later pumas can do it in theory as the connections are physically there you just have to hope theres no software issue restricting databus communication to diagnostic equipment only!

oh and if you just want a little more power then just tune a 1.6 with cams, exhaust manifold and system, puma inlet and a remap. Job done.

okay excellent thank you
yeh i have 4-1manifold, sports cat and piper cat back, k&n panel filter,

set of shawspeed cams and a remap will see over 140bhp on that no bother

exactly mondeoman so what do you hope to really gain?

after say cams a light port and polish and a remap then surely the next jump is to go for about 160-170 bhp anyway. which is going to be cheaper on a zetec e/R or st170 lump.

smudger068

all i wanted to no was is it as simple to do the conversion on a focus, as it is to do on the fiesta, if i wanted a st lump i would just sell my focus and buy an st170 because there cheap enough as it is, just wanted abit more power for the road so i havent got to drive the 1.6 engine so hard without spending a complete fortune, because my focus is stripped with a roll cage and bucket seats, it fairly nippy compared to the 1.6 in the first place...also wanted the puma engine so unlike the st170 lump i wouldnt have to change the brakes, suspension looms etc etc..and being 19 i cant afford insurance on a st170...if insurance wasnt so high or non exsistant i would own a cossie...just wanted bit more power without to much hassle, and insurance going to high

Not really, the head and standard valves are good for 200bhp n\a as standard so a port and polish would lose you a bit of driveability for no top end gain, once you have the cams in, it would take a simple change of ecu and a set of direct to head TB's with some new valve springs and rod bolts and you're knocking on 185+bhp. Which is cheaper than fitting a zetec-e then having to do the same thing anyway

Good engines these 1.6 sigmas are, very underrated and not many folk know much about them

Shawspeed SS4 cams then and a remap. Job done

you reckon a well sorted head, TB's and suitable management would be cheaper? I guess if you were lucky on ebay maybe but a decent head and cams is gonna be a grand, TB and ecu another grand, and at least 3-400 on mapping even if you get a good base map! thats assuming he does most the fitting himself.

I spent a bit more on my 1.7 to get 225bhp and on that spec youd only drop about 15bhp on a 1.6. although i did go mental on roller barrel throttle bodies from works rally car with maclaren designed throttle intake trumpets (£3.5k of which £1k was the carbon trumpets!), full big valve head with rally cams and omex 600 which aint the cheapest!

ST170 it. Got a couple of projects I'm involved with using ST170 engines, both should be little stormers

You arent reading properly, you dont need to sort the head, its good enough as it comes for 200bhp n\a

all he needs is cams + remap for 145-150 with his current setup, easy done for about £700 all in

the to go to the next level ie circa 190bhp direct to head tb's with fuel rail etc and the ecu and rod bolts/valve springs, deffo cheaper than trying to get a standard zetec-e to that level, which would also require cams/tbs and ecu, unless you used an st170, in which case, have fun with the loom/ecu

you say about insurance, i was 19 no ncb but license since 17. 1300odd. Not bad for my st170 all mods declared. Only thing i cant do power mods but its fast enough for me as i got a lil un on the way its more for looks i have it.

Oranoco

How the fuck did you manage that? My brother was paying £1600 to insure his Fiesta RST at 19 with NCB and limited mileage.

rsfido_1989

ha. Well first i am member and rep for s2rs and they liked that. And it actually got my insurance down in price to declare my mods, dont understand but it did ha. Standard st they wanted 1800. . . Btw its adrian flux. I love them because i wanted my own insurance and didnt want a shitty 1l rotter!
