600bhp 1 Series
Discussion
OP, looks like a great car and thanks for posting such an enjoyable thread.
I would also go for the auto. I don't like the offset driving position on these, which is really noticeable on the manual.
The auto really suits the power delivery and torque too. For me, they make great GT cars, road noise aside, so auto all the way.
Any idea what that M3 with the airbox made at the wheels? I have a very similar spec, so quite interested thanks.

I can only speak from my own experience, but I tried the M140i with both the manual box and the auto (having exclusively owned manual cars beforehand), and found that the manual wasn't particularly enjoyable to use, being rather rubbery and notchy. The auto, however, is IMO an absolutely perfect pairing for the B58 engine.
I formerly owned the M135i LCI and had the same experience. Don't think of it as manual vs auto, more the auto variant of these cars works better than the manual version. The car was my first auto and I've replaced it with another car with the ZF 8 speed. This is my second auto, and it’s a huge improvement over the old ZF6 that I had.
Time for a bit of an update.
There has been a bit of this:
Lots of this:
And generally it's continued to be very well behaved. What's the old saying? If it ain't broke....
Ah.
Best laid plans. I've been having an increasing drivetrain vibration which you can feel through the steering wheel, almost like a wheel balancing problem, except only under load. I had a look at the rubber donut bushes that connect the diff / propshaft / gearbox however they are in good order, so I decided to swap out the engine mounts for new OEM ones. What a hideous job that was.
That was the only photo I managed of that as the rest of the evening was spent hoping the crudely propped up engine support bar didn't fall off whilst we were wrestling the subframe down onto some wood and transmissions jacks to get the clearance to get the mounts out. The old ones didn't seem unduly worn, however changing them has been a revelation and it's back to it's silky smooth self. Time for a service whilst it was on the ramp...
Happily my oil filter came out without tearing itself to bits, a common B58 issue.
Whilst it was there, my pal offered to do a little exhaust modification and it seemed rude not too. So the middle section has now been modified, the centre resonator is still there, however the small middle silencer box has been cut open, wrapped up to make it straight through, and rewelded.
I was always happy with how the car sounded, but I'm like a kid at christmas now. It's got a more purposeful deep rasp to it than before and it really howls when you're further up the rev range, but by maintaining the centre resonator there's no drone on the motorway. It's perfect imo.
That left me in a dilemma. Here I am with a freshly serviced, refreshed and tinkered car that's been running the Pure800 hybrid turbo happily for a year at standard stage 2 boost, barely tickling along.
I've chatted more with Marc at Williams Performance about where to go and what to do with it, and we've now switched the car from BootMod3 software to MG Flasher, which has some nice trick features and custom code, but most importantly, is the platform that the new tuner wants to work with.
It's in the process of being mapped now by a guy in Florida who has been doing really well with the Mk5 Supra B58 Gen 2 platform. There are a number of differences between the Gen 1 and 2 platforms which we're in the process of working out, but it's looking really promising so far, and the wick is getting turned up.
Plenty of work to do on it yet before it's properly dialled in and making good times, but it's on the way. I've had my first EML and I'm having a bit of a mare with a fuel tank vent valve reporting a malfunction but it's getting changed out so hopefully that will sort that.
Sadly we're not ending on a high note, I was going out datalogging on Sunday and was bearing left out of a T-Junction, looking for traffic to my right. Because of this, I didn't see the grand canyon in front of me and promptly blew out both drivers side tyres spectacularly at 10mph ish. An expensive mistake as I'd not long put new tyres on it.
Still, luckily the wheels survived and there doesn't appear to have been any other damage. I also needed to align it anyway as the subframe has been off for the engine mounts and thankfully I hadn't done that yet, so that's a small bonus.
Thanks for reading all that if you made it to the end!

800bhp on the dials?!
Surely not! That’s absurd
It's optimism at it's finest haha. To be fair, the sports dials are a bit of a gimmick, they're not an accurate representation of what's going on, they're basically more of a "throttle position / load" dial with "hp / torque" on them to look sporty. Surely not! That’s absurd
That said, previously I've been running around 20psi of boost and very conservative timing, and I've seen 28psi so far on this new tune. It's definitely more lively. I'll also be getting an E30 version of the tune which should make more power again.
It's a very silly little car, but it's very good fun.
Love this thread as I enjoy seeing what a pretty fast as standard car can be "upgraded to". I've done just 1000 miles in the last 5 months in mine, first MOT passed and a brand new set of tyres.
I have to make the final payment this year as I come to the end of the 4 year PCP, I specified it as a keeper and that's still my current plan even moreso now that it's mileage is so low. I still enjoy driving it and can't think of anything else (for sensible money) that would equal it's abilities.

Great thread mate and lovely car... really not helpful to my modding itch though 
How do you find the Goodyear’s? I want a set of 235/40/18 front and 265/35/18 rears for my Apex’s but there isn’t a huge amount of options available (Eagle F1 Asy 5 or PS4).
Is there much less dry grip than the PSS? I just assumed you could get a PSS in 265, but evidently not! Going to run winter/all seasons on the original wheels so low temp traction not as much of a concern, hence why I’d have liked the PSS - may drop down to a 255 if there’s a lot more traction than the F1.

That’s a pisser about the tyres. Did you manage to claim anything back from the council? 100mm is a fair old depth.
Claiming for the damage from the Council is fair enough but I'd hope everyone understands that is is tory austerity and chronic underinvestment in council services that is to blame for the state of our roads.culpz said:
It's absolutely staggering how good these cars are on fuel for their engine set-up and power. 27 MPG is what my dad's currently getting out of his M240i, which is exactly the same as what I'm getting in my Cupra 290. Quite how a 3-litre 6-cylinder can be as fuel efficient as a 2.0 4-pot is simply astonishing!
I think the ZF8 is the (not so) secret to that.EffBee said:

This will be controversial I think as a lot of people really rate the Eagle F1 Assy5's, however I just can't get on with them at all. No matter what pressure's I try, under hard acceleration in a straight line, the car feels like it's constantly shifting laterally a few inches, to the point where you feel you almost need to correct it, but it sorts itself and shifts the other way, it's pretty un-nerving and not a problem I had with the Pilot Sport 4's I've been running. The general grip seems ok, they're wearing reasonably, the wet grip is fine, but I won't be fitting any more, I'll be going straight back to PS4's as soon as possible.

Any vids of the exhaust? I’d like to do something about mine this year (want to leave the res in place).
I haven't heard anything yet, but the pothole was filled in the next day haha.Any vids of the exhaust? I’d like to do something about mine this year (want to leave the res in place).
I'll sort some videos out of the exhaust today and upload to YouTube, I'll post them here tonight. I would say as usual, the camera doesn't really reflect the true noise as it were, I'd completely recommend getting the front box mod done, leaving the res in place and running the MPE back box, the sound is perfect for me.

With the greatest of respect, there is a sub forum for politics discussion and I think this is better off being tackled across there.Zombie said:

Absolutely. I'm planning to swap my ZF8HP50 out this year for another ZF8, the HP70 from the 30/35d cars. This can handle much more torque as I'm pretty much on the limit of my box. I've been out in a car that has had the swap and xHP do a map for the HP70/B58 combo and it's absolutely incredible. Shifts noticeably faster than mine does, its pretty much DCT and I thought mine was close.Videos as mentioned earlier, I’ve got a one of a few gentle revs:

And a takeoff. It’s fairly pedestrian but I don’t launch the car hard anymore at the power it’s at as it’s not really what the cars about, and there’s plenty of cars in the states snapping shafts or twisting the prop once you get to the 550whp mark.

Seen you about probably ages ago due to the covid time machine but recognise the plate and badge. Cracking car. Can’t wait to see the planner changes.
Nice to see Marc @ WP getting some nice praise to, friend of a friend.
I’m currently carless and happy during lockdown but the thought of these is starting to itch!

I've experienced similar things (also accelerating whilst changing lane) when I've strayed away from Michelins on the Monaro. For me, it has been a mismatch in the sidewall stiffness of the front compared to the rear.This will be controversial I think as a lot of people really rate the Eagle F1 Assy5's, however I just can't get on with them at all.

I actually had a similar problem when I had PSS on the front and PS4S on the rear, swapping them front / rear sorted it, so I don't think it's the quality of the tyres, just that if the front has a stiffer sidewall than the rear, it can give a nasty pendulum sensation on some vehicles.
Many years ago I put some Avons on the rear to try, sold them within 500 miles as it just ruined the car, was horrible to drive, even just changing lanes on the motorway it felt like it swayed a bit, just very unsettling.

Have you thought about moving to a wider wheel? I suspect with 600bhp through a 245 rear contact patch anything is going to be somewhat limited in its ability to put power down.
I was out and about today and ended up parked next to another PH'ers car, so I grabbed a quick photo and remembered I was probably due a thread update.
I don't know if we have a terrible parking award, but if we do I clearly won it today. In fairness I was only there 5 mins and the car park had hundreds of free spaces.
Bit of a frustrating period with the 140 lately however things appear to be on the straight and narrow again, and it's been entirely my own doing, not the cars fault or any components.
At the start of May, took the plunge and went for the upgrade I'd mentioned previously. Out came the trusty old ZF8HP50 which has put up with far more abuse than it expected in 70k miles since it left the factory. I should mention, although when checking the clutch values with ISTA / xHP they are clearly showing a reasonable amount of wear and the quickcharge times have increased, the box was showing absolutely no issues at all, shifted great and was producing no TCU error codes or any symptoms of problems. It's operating outside of it's manufacturer stated limits and has been for some time, so they're a great strong box imo.
Here we are having pulled it out:
Another big shout out to Marc at Williams Performance here, because we ended up with an absolute head melter of an issue after this swap that took around a month to resolve and he was an utter hero throughout, quite a few late nights / early mornings have been endured.
We dropped in the shiny new (to me) ZF8HP70:
Physically for this swap to work, you need an N57 330d flywheel and torque converter, so those parts went in too:
Once the necessary coding was done so the car understood it had the HP70 and was "allowed" to have it, I flashed it with xHP's Stage 3 TCU map. They have a specific software map for this box in the M140i which is super helpful.
And then pretty much it all went wrong
Test driving the car showed immediately that there was a rather horrendous contact / rubbing / grinding noise, but only when turning right under throttle. It wasn't apparent just coasting right, and even under power turning left it would disappear. The box changed perfectly, launched fine, showed no TCU errors, clutch values were all brilliant. ISTA gave no clues to any issues, and the car drove fine apart from this awful throbbing, which sounded like it was coming from the passenger footwell.
The problem we had was that there was absolutely no sign of anything under the car having contact marks of tell tale signs of rubbing / knocking etc. When fitting the torque converter one of the tabs that bolts it to the flywheel was slightly bent from shipping, and we'd straightened this out, but Marc wondered if the torque converter could be faulty as we were struggling at this point to think what it could be, so the box came out again and I acquired another torque converter which was in perfect condition and we fitted that.
The noise was identical, so that sucked as it's a fair old job to take the box in and out.
Over the next few weeks we carried out the following:
Checked subframe bolts and engine mounts in case anything loose (have to tip engine on mounts during box removal)
Serviced Gearbox
Serviced Diff
Replaced both propshaft guibo donut joints
Replaced propshaft centre bearing
Replaced gearbox support mount
Checked all exhaust hangers and downpipe bolts etc
Along with removing all undertrays and continuing to test the car and try to narrow down the noise. Eventually we both agreed there was a chance the box could have some sort of bizarre internal fault as it is a 2nd hand unit.
Cue yet another late night and gearbox swap. The car rolled off the ramp at 12:40am on a Friday night / Saturday morning and I excitedly took it for a test drive. Whereupon the noise immediately reappeared exactly as before. Baffled, gutted and annoyed.
I then just drove it for a few days out of frustration, hoping it would either get worse or better but hopefully give some sort of clue as to what the problem was.
By fluke, Marc happened to be doing another swap and ended up fitting the gearbox support mount to the gearbox on this particular car in it's two seperate parts. Normally it's easiest to bolt the bracket together in one piece on the floor, chuck it on the box and then just bolt it to the car when the box is lifted up into place.
When he was bolting the two parts of the mount up, he found that with a breaker bar on the bolts, it was possible to shift the gearbox just enough on it's mounts so that the edge of the gearbox casting JUST touches it's own mount. Sigh.
It was literally JUST touching too. 350 miles in on my car, and it had only just made this tiny little mark when I removed my mount again to check it.
30 seconds with a flap wheel on the grinder to take 4mm off the mount and box casting and the noise is completely gone and the car is fine. Talk about a ball ache. However I'm delighted it's sorted, just one of those things. It was the rear left of the box that was touching, so I suspect the lateral force of the car turning right along with the twist on the mounts in the driveline under power was just enough to make it touch and cause the knocking.
Now that that's sorted, it's brilliant and I've had a chance to give the new box a bit of a shakedown. Changes are brutally quick with the xHP map, and the box should take up to sort of 1100/1200nm on the xHP map with their line pressure bump according to them, so I shouldn't need to worry about the box again going forwards.
From the factory the M140/HP50 has these black rubber guibo donuts at both the diff and gearbox end of the prop:
I've replaced these with tougher stiffer items that are supplied to the gearbox end of the HP70, however I've replaced the diff end one on mine also. This has noticeably taken some of the slack out of the driveline and sharpened the feel of the car up.
To celebrate it being in rude health again, I've had full screen CarPlay coded to the car too. Standard CarPlay only utilises 2/3 of the pro nav screen for some ridiculous reason which is infuriating, so this is much nicer to use and look at:
It's also had a bath and I've adjusted / tightened up the handbrake mechanism:
Tuning wise, the guy in Florida didn't work out. He was clearly too busy and thinly spread and the waiting between tune revisions / progress was too frustrating so I called it a day and I've since been tuning the car with a guy called Kirill Olyabiev (ODINTuned) from Russia. He seems to be a total wizard with the B58 platform and my pump fuel map is just about complete. The car feels phenomenally strong now and is making 28psi of boost peak.
In the next few weeks hopefully we'll get an E30 ethanol version of the map completed too. At that point I'll head back to the dyno and see what the car does in comparison to last time. It's not ideal for tuning at the moment though as the ambient temps are so high.
If you made it to the end of that marathon thanks for your interest!

To celebrate it being in rude health again, I've had full screen CarPlay coded to the car too. Standard CarPlay only utilises 2/3 of the pro nav screen for some ridiculous reason which is infuriating, so this is much nicer to use and look at:
It's also had a bath and I've adjusted / tightened up the handbrake mechanism:
Tuning wise, the guy in Florida didn't work out. He was clearly too busy and thinly spread and the waiting between tune revisions / progress was too frustrating so I called it a day and I've since been tuning the car with a guy called Kirill Olyabiev (ODINTuned) from Russia. He seems to be a total wizard with the B58 platform and my pump fuel map is just about complete. The car feels phenomenally strong now and is making 28psi of boost peak.
In the next few weeks hopefully we'll get an E30 ethanol version of the map completed too. At that point I'll head back to the dyno and see what the car does in comparison to last time. It's not ideal for tuning at the moment though as the ambient temps are so high.
If you made it to the end of that marathon thanks for your interest!

I was out and about today and ended up parked next to another PH'ers car, so I grabbed a quick photo and remembered I was probably due a thread update.
I don't know if we have a terrible parking award, but if we do I clearly won it today. In fairness I was only there 5 mins and the car park had hundreds of free spaces.
Ah the Mrs had the car out today. I'm WFH so my motorway cruiser sits on the drive most of the week then she takes it out for shopping! Bit of a waste and I often thought I should have kept the mineral grey 3 door M135i! Sounds like you've had a busy time with your 140. Some impressive work done on your car now. Can't imagine how quick it will get down the road. I don't know if we have a terrible parking award, but if we do I clearly won it today.

She picked the best space in the car park for avoiding car park dings, I love that one Cheers mate, it's a doing a great job of ensuring I never have enough money to develop a drug or gambling habit

That's only because she's curbed 2 alloys and dinged the rear bumper in recent weeks. Cost me over £600 so far and it's still standard! Cheers mate, it's a doing a great job of ensuring I never have enough money to develop a drug or gambling habit
