Yep, got the cash there, might as well.
Yup. See what it will do.

Might be biggrin

But will be doing something else with it.

Need to sort the brakes before it has any more power, they are fine but the front have a lip and I need to change the fluid so might do new disks and some Yellowstuff pads first.

Also need to change insurers as Admiral do allow mods but only up to a power increase of 25 %, stage 4/5 would go over that by some margin, so will move it to Brentacre, Flux or similar. Though they allow them they don't replace them if it gets nicked, you just get standard 2015 ST money, not that plus 4 grands worth of mods.

I could never quite bring myself to pull the trigger on "stage 4". All my suspension, bushes etc were bought with the intention of going for a different turbo but I wouldn't have wanted to do it without also getting a LSD fitted and suddenly it becomes pretty serious (for me) money - and I've been bitten before by going too far with FWD cars....300bhp Citroen AX anyone....although by all accounts the Fiesta handles it well.

Have a recovery beer and hit "BUY" I reckon biggrin

I cant fathom how it manages the traction it has with 240 bhp, in the wet, we had an 850 T5 that had less power but was really unruly, this just grips even in the wet, got some wheelspin accelerating hard uphill earlier but thats it. Its just not an issue.

Its getting done one way or another, just need to sort a more suitable insurer, but will ring Collins tomorrow and get it booked in.

Hmm, just been out, thinking stage 5 might be beer induced overkill and 300 bhp will be more than enough at stage 4.

It feels pretty rapid now, feels quicker than the BMW, obviously isn't but the noise, having to change gear and the fact you are ragging it to death makes it feel faster. It still piles speed on but not in that effortless manner the BMW had.

It goads you into going quicker, on B roads it feels like a little rally car. Its faster than I am, am re learning heel and toeing.

Upset someone in a Merc GL Something, if you insist on driving in the right hand lane on an empty dual carriageway, maybe expect knobheads in small noisy red cars not to wait.

Its booked in for the CP4 upgrade, which will give it around 300 bhp. Bottled it on the CP5 as think its probably overkill for what I want plus its another £800. Its pretty good on the current level but I just want it to take that step up, shouldn't affect the drivability either. Plus I think its well within the comfort zone of the engine and Collins major on safety/smoothness with their maps.

Have got a quote from Adrian S flux for it when its done and that was ok (£396) Admiral don't want to insure it once past that level of power. Didnt have my son on it though, he said that will add quite a bit to it so he might not be happy if he isnt on it, will see nearer the time on that one, he can make a contribution, he uses it when he comes home from Scotland and he gets a lift off his colleague so doesnt have a car and nicks mine.

Did 250 miles or so over the weekend, wife not that keen on riding in it due to the jiggliness, but it is quite happy, despite lots of stop start and some extended stretches at 85/90 it still did 41 mpg.

Round town it does make you drive like a saint as otherwise, it makes too much noise and you look a right knob.

Going to order some disks and pads soon, prob will go with oem disks and Yellowstuff pads, was looking at the Ferodo DS2500s but they are like £160 for a set of fronts, not sure I can justify that.

Don't the DS2500 need warming up a bit? I don't know about Yellowstuff. I've used Ferodo Premier and the newer Eco Friction pads on various road cars and been very impressed with them. I'm obviously not using them for sustained periods as I would on a track, but they need little bedding in, give consistent braking and resist fading on a long, twisting downhill with hard braking.

I'd imagine 300bhp to be an absolute riot for sure. driving

Mine's standard and scrabbles for grip... 300bhp will be pretty loony!

Good luck.



(My S-Max 2.5T was 365bhp / 525Nm. That left 11's on the road through the gears laugh )

Its funny, not had any traction issues to speak of at 240 bhp, I think its mapped fairly conservatively and it has Pilot Sport 4's on. Plus its fairly warm, it just hooks up and goes, amazing really as loads of older cars with that power in fwd were pretty unruly.

300 bhp in a little 1150/1200 ish kilo Fiesta does seem loony, though if you talk to the FB group its pretty middle of the road, plenty running 360 plus which I think is probably, for me, a step too far. Plus they tend to festoon their cars in cosmetic mods, nothing against that but I want mine to look pretty much standard.

That will go in the goes well category even at 240bhp in a light(ish), small car.

Incidentally my old Impreza weighed about the same and made 394bhp but I found it to be exciting over 350bhp (probably because it had AWD and handled lots of power with ease). I also kept my car looking totally standard and even had the front mount intercooler coloured black to make it difficult to spot. The only thing I did that I didn't really like (at the recommendation of the engine builder) was to fit a larger exhaust which annoyed me as it droned on part throttle and was far too loud for me. The M135i/M140i pull off the trick of providing lots of comfort, they are quiet but can sound great and be fast when required and then go back to GT car when tootling around.

Ultimately I think all cars have a sweet spot and turning past that can result in poor reliability, heavy use of fuel and consumables and poor comfort (which is ok if it's not your day-to-day car). In my experience many tune past the sweet spot and then find their cars difficult/painful to maintain/use and sell before long. I have no idea where the sweet spot is with the Fiesta but am keen to see how you get on with tuning it further!

Mrs was moaning about mine today as it was too ‘jiggly’ on the motorway for her to drink her tea! laugh

At the moment its no more of a pain in the arse than a standard one, went to Wales and back with a bit of driving whilst there and there didnt seem to be a downside. The intake noise is a bit silly but I quite like it now. Can hear everything the turbo is doing. Its pretty torquey

Its fairly long legged, not like the M135i was, and that is a more comfortable car but it will sit at 90 at 3 and a bit thousand RPM, its a bit noisy.

Interestingly my wife didnt complain once about feeling sick, my old CLS used to set her off, air suspension and a very torquey, quiet V8 seemed a bad combination so the busy ride and racket seem to avoid that problem.

Am hoping it retains the stock feel but more of it, even as standard they are quite grunty low down, the 280 is apparently a smidge more laggy than standard but the 270 hits the sweet spot, the chap at Collins says he personally prefers the CP4.

Its easy to get caught up in big numbers but dont want something thats a pain in the arse, running on the ragged edge, take a step back and have a think, 300 bhp from 1.6 litres in a Fiesta should be plenty.

This is the first time I've heard of stage 4/5 upgrades for a Fiesta. What power would it be, and what has to be changed in order to stop the engine going boom?

That’s going to be a hoot at stage 4; that much power in a light car.

Really not a lot needs changing, it's a strong engine. There are supporting breathing mods that can be done but they aren't essential.

"Stage 4" is between 300 and 330
"Stage 5" upwards of 350 (needs bigger injectors for top power)
