hello
i have recently put a 1.6 engine into my focus as i blew the 1.4 engine up lol
however its still slow and i was wondering how i can improve the performance of the engine without spending a lot of money. does the 1.7 puma inlet manifold fit this and make much difference? i was also wondering about changing injectors and the throttle body to a bigger one off a 2 litre or something? can someone help?
thanks

 

all of what you suggested will make bugger all noticeable difference even if it all fits,your easiest option is nitrous

 

easiest option is to sell it and buy an st 170 (getting cheap now) or focus rs mk1

Agreed, sell it and buy one with a bigger engine, will be cheaper on insurance too than a modified 1.6

 

Didn't the formula ford cars run 1.6 zetecs? I'm sure I saw on 5th gear once they had a challange where they swapped a 1.6 zetec from a focus or something into a formula ford in a compertition against some colleges (probably a clip on youtube somewhere), thay had to change some of the components to formula ford spec, I think they changed the inlet, ECU, and the sump to a dry sump, maybe yopu could try and track down some of the parts and fit them to yours if you want to keep the standard lump in

 

1.6 inlets flow plenty of air, changing it will make no difference. Some ss4 cams, a full exhaust in. mani, panel filter and a remap/chip to suit the cams can see up to 150bhp on the se engines. But, personally, I'd just wait and buy a faster focus...

 

The SE isn't a bad engine really, you can get around 135-140HP from them with cams, exhaust system and a remap (Bearing in mind a 2L is 130HP), see www.shawspeed.com for more info.

Weight saving! Rip everything out!

 

puma racing 1.7L ?

 

Sell and buy a 2.0 esp or a st170. I cringe at the money ive spunked on cars in the past, should of just bought a faster one instead.

 

The ST170,s are a cracking car.

 

I had 1 not so long ago. full ss exhaust sports cat, ss manifold, air filter, dream science, proper service.

back disc conversion and st170 fronts.

it was good.

 

Been there, done that, it honestly isn't worth the hassle trying to make a small engined car fast. Leave the money in the bank until you can afford something quicker straight out of the box!

 

Swardy,
I too have a 1.6, a 'Chic' ltd edition. I'm trying to make it the mintiest of minty mint versions of the 'Chic' there is (with maybe one or two subtle mods, such as a K&N panel filter, cat back replacement exhaust, MP3 wheels etc)

If you want performance, do as other posters have suggested. Save the cash, get an ST170 or MK1 Focus RS. Handy if you have a garage if you get an RS depending where you live to keep it out of the way of covetous theiving eyes.

If your keeping the 1.6, just keep it clean and use it as a cruiser rather than a racer lol

 

I've got a panel filter for sale if you are interested....

 

thanks for the offer Rich, but I've already got one & fitted it.

cheers though mate!

 

Sell the thing and get another Focus with an engine that has enough torque to haul its lardy backside with. A 2.0 litre is the bare minimum you should be looking at, preferably an ST170 or an RS if you're really serious.

 

Mate doing all of that would cost more than the car is worth and prob make it a nightmare to insure. As above save up till you can buy something quicker out of the box, then mod that.

 

Throw it off a cliff.....Sell the thing and buy a bigger engined car mate best bet.

 

I would either sell up and get a 2.0l, or accept it will never be a rocket ship, maybe lower it to improve handling in the twisties and look at keeping it well serviced and check on stuff like bushes etc to keep it tight handling, then maybe a decent exhaust and filter to help breathing.

Not really worth chucking cash at it as it will never be quick and will be £££££ to get any big improvement, big car, small lump = slow.

 

Does anyone know if the 1.4 and 1.6 gearboxes are the same? my 1.6 has the gearbox off the 1.4 but top end speed is CRAP! lol

 

What you mean by crap? The 1.6 top end is crap aswell.

 

crap as in it will go to 105mph then slow down to 100mph and wont go any faster lol dont know if its gearbox of something to do with the coilpack or spark plugs or what. any ideas?

 

Then you have something wrong, 1600 will do 105 with ease, why are you interested in top end speed, you can't use it anyway really? I would be more interested in bottom end power personally.

Martin

 

any idea what the problem could be? and what can i do to get more bottom end power? cheers

 

Needs a good service/new coilpack? That's where I'd start tbh...Other than that, is it burning oil?

 

its not burning oil. found out last night its still got the 1.4 coilpack that could be why!! lol

 

All coilpack's are the same, think there's only 2 different ones across the whole ford range, and the only difference between these is the ht lead fittings!
