hey, i am buying a ZR 105 soon, had a mate with one which was pretty nippy, was just wondering if it is faster than other 1.4 cars like a corsa or clio?

hoping it will be as i dont have a fortune to spend on mods

cheers

They are pretty nippy as standard and put a lot of 1.6's to shame.

+1, 1.4K is as powerful as the average 1.6 from other manufacturers.

It's more powerful and Probably lighter too. i've done very little to mine and i saw off a mates 1.6 civic v tec (his was a 05 ) it wasn't exactly an old car. sort out the suspension and get some decent tires and you'll be amazed how you can splat your passangers against the door while going round a roundabout (ONLY DO IT WHEN ITS EMPTY and within the speed limit) there's a funny one round near me thats a 50 :)

Well to be honest i've asked around and most people don't recommend doing too much to the 1.4, they recommend either, buying a 1.6 or 1.8 zr or plonking another engine in.

i've uprated my exhaust, going to do the manifold next. that i think will be it as far as the power upgrades go, might stick in an induction kit, not too sure yet.

all im going to say is the 1.4 k series is already a tuned engine. if you do too much you risk doing damage and reducing the life of the engine.

If you want to go quick. buy a 120 or a diesel. The 120 is massively quicker than the 105 in terms of 'feel' and for less than £500 you can get the diesel to 160bhp.

indeed, im trieing to figure out what engine would work well in a ZR, reckon K20a V-TEC'd ZR would be awesome and would embarrass a FN02 Civic (Which the engine is from) in both power to weight and cornering

the 1,4 is a pretty well tuned engine, when you think the TFs 1.6 engine (which is in my TF) is only 9bhp more!!!

my mates ZR (soon to be mine) was at a similar state of tune ot my TF (standard internals just a stage 1) and could keep up with me off the line (i'd usually pull about a car length ahead due to better traction off the line but after that i didnt leave him at all till we went past the national speed limit!

so the 1.4 is definatly a heck off an engine

compare that to my TF on runs with the TF crew and i had no trouble keeping up with the TF 135s (Same 1.8 engine as the ZR/ZS but with higher lift cams)

mind you i countered my 21bhp power defect with lightweight alloys, good tires and bravery lol

the 1.8 engine however has tune-ability... but to answer your question the 1.4 K series engine is quite frankly awesome! can you tune it and keep reliability? probably not.... do you need to? probably not! lol

Fair enough, yeah at 18 insurance will be silly! I owned a group 17 Rover 620ti at 19... paid £2,000 a year for insurance! It did do 0-60 in 7 seconds though lol.

the 105s are good little cars, handling's good on them too. the engine's brilliantly tuned for the size of it, and the car itself's a lot lighter than other hatchbacks.

in terms of the Fiesta STs, I can **** them off in my old 924, and that's only 125bhp at the flywheel - RWD, good handling and Toyo Proxes R888s nice and warm on track ftw :)

when you get the ZR, the first mod to look into should be a free one, take the exhaust manifold off and get the weld blobs taken out of it, they can seriously restrict it, i think i'll see about mine when i'm off work next week.
