Car: M135
Default Cost to maintain/upgrade m3

So I currently own an m135. I was looking to get an f80 m3 next however they are abit out of budget

Ever since the M3ntal meet in Birmingham as having a really good look around some fast road/track focused e92 m3s I canít help but trawl the classifieds every few days looking for my ideal example

Donít get me wrong they are a good looking car, but with new wheels, brakes, suspension and a few aero additions they look superb.

So I now have a few questions I hope you can help with

Iím a complete n/a newbie. Pretty much all of my cars except a few 1.2 corsa have had turbos, the amount of videos etc I have watched on YouTube makes me want that noise in my life.

So from a tuning point of view, exhaust, intake and remap what costs are we looking at? From some brief research no huge gains can be made without spending huge so that wonít be happening

Most likely Alex arc 8 wheels I think they are called, uprated suspension or just springs? Costs? Front lip and rear spoiler? Are these bmw supplied parts or aftermarket?

I guess Iím trying to work out the costs for the upgrades as a ballpark and get them done ASAP so an6 help is appreciated

Now when buying a car I have always tried to buy the very best example possible. With the e92 it seems prices vary a lot.

This is my ideal example although I think itís got to be overpriced as itís the most expensive e92 available. What are peopleís thoughts?

Now it could be pretty stable on price and be a good investment in one sense as the colour combo/spec seem rare however if it got turned into a fast road/ track car would it just kill the value?

Am I better buying an older car with more miles and not worrying as much about the values etc?

Sorry for the messy random post. Hopefully you fellow cutters can give some good advice

Tuning - capabilities for this car are low in bhp return without costing thousands, with a £600-£800 budget you could do a decat and remap on the cheap. I wouldn't do any of that cheaply if you're buying a newer, less mileage example though. Evolve do a stage 2 remap and decats for £1,249 which yields 15-20bhp and they're a reputable tuner.

Supercharger kits are available but are costly especially if you replace/upgrade the rod bearings at the same time. You're looking at roughly £8k-£9k for a 600+ bhp kit with uprated bearings. Obviously if you know people in the trade, friends etc or are mechanically inclined you could get it installed for less than this. There are a lot of supporting mods/costs to consider too such as wider wheels, wider tyres, bigger brakes and more servicing.

Upgrades - depends how you're intending on using it, I just use my car on the road and just have springs, it's a nice drop and barely noticeable in terms of ride quality. They were Eibachs and were a couple of hundred installed at a specialist.

For really, really good coilovers you're looking at £4k (I think) brand new. EDC is a 100% must have if not. For wheels most people, if they're changing them, go for AG M359s which are roughly £600-£700 from CMWheels. If you're intending on hammering it on track at some point you will have to upgrade the front brakes, the standard brake set up is good for one track session at best, OKish for the road.

To get the power of out this car you have to ring its neck, it does not deliver power like a turbo car. There's hardly any pull until you get over 5k+ rpm but when you do it's pretty quick. It's probably just a bit faster than your M135i but it won't feel like it.

The example you showed is nice. This is just my personal opinion and I don't know if it's reflected in the wider car buying market but I wouldn't buy a car with that much red leather interior. Otherwise it's pretty much perfect. No one can predict the future price of these cars, obviously well maintained, limited edition, lower mileage cars will fetch more than their counterparts. Personally I think they will to a degree, maybe not as much as the E46 or E30 but up there.

It all depends on what you want to do, you'd have to baby a car like that to retain the value in it, if that's what you want that's what you do. If you want to modify it extensively and drive it daily and/or track it I would go for a slightly higher mileage, less pricey example and spend the rest on mods.

Simplest advice - when you test drive it, wring it’s neck. Literally wind it round to 8k+

The ratios are long, you won’t be used to the car, you’ll floor it and probably naturally upshift around 4.5k. You need to really push it hard to get the best out of it. Let her sing.

Best thing to do is got primary decats and replace the filter in the air box for a bmc and map the car gains are around 40hp.

You can do a box mod if you want more noise.

Suspension kw club sports are £2500,big brakes for the front are £2500 roughly too. If you want a track car you won’t want 359 comp pack reps as they are heavy arc 8’s are way better and lighter.18’s are better for track too,wheels and tyres are around £3000


An e92 will smash a 135i if driven correct,always need the revs above 4K ideally and rev the car right out.rev it past 8k! Then they are fast.

If you keep the car low in the revs and don’t rev it out a 135i will fly off,the beauty of this motor is they rev and don’t feel strangled up top so it’s a real joy to rev out.


Once you do the rod bearings you can go upto 700hp on the s65 so tuning is good just expensive.

Great cars road or track,chassis is amazing.

I went M135i to E92M3 too. The whole event of driving, even with no mods, is far more involving than the M135i.

Good luck with your search. Enjoy.

Tricky, my mineral white and fox e92 LE500 is for sale on Autotrader. It’s the one with all the upgrades but leaving you to do whatever you want on the exterior. Today the front wheels are being powder coated and new Michelin Pilot 4S being fitted to match the powder coated rear wheels and 4S fitted s few thousand miles ago. The wheels were un-curbed but I just like to get them refinished when I change tyres. Tomorrow it will have 12 months MOT even though 3 months remain on the old. Monday 4 wheel Hunter alignment. So around £600 spent on it in the last week. See what you think

Won't comment on performance upgrades. I will say you should get the one you really want with the right spec so think hard. I don't have dab and it drives me nuts..... If you're upgrading to coilovers don't bother with edc for example. You mention butchering a car that nice so consider a cheaper car with good history. Besides if its cheaper then youll have more money to upgrade it. Consider one that's had stuff done already if you can else you'll be spending money trying to get it the way you want.

Also turbo to an s65..... it's taken me 6 months to really start enjoying my m3 after owning a Megane rs and various other hot hatches over the years. But it is special . Went in a 240i the other day and it just felt so asthmatic up top. Nice torque etc but it just left me wanting where the e92 m3 starts to deliver the good stuff.

I think the answer is "It depends"

The cost depends on how far you want to go. I think we all agree here that the rod bearings should be replaced as a matter of caution? So factor in £1400 ish for that.

After that, there's the possibility that the throttle actuators will fail (if theyve not been upgraded) - so factor in £610 fitted there.

So already we are at £2k - but you have added value to the car should you come to sell it.

In terms of Intakes - the good ones yield around 9-12bhp - Eventuri, Karbonius, Dinan etc. With the addition of a primary cat delete and a tune, there's no reason why you can't see at least 450bhp.

However, if I were you, I'd forget about power mods if you want to make this a track car. The first place you should start is brakes - the standard discs are floating and are decent, but you will need uprated pads, fluid and ideally lines. If you don't, you'll cook them within laps.

From brakes, look at suspension - again, depends on budget, I'd look at EDC cars regardless however found non-EDC cars fairly compliant. You could do lowering springs with this setup. From there, there's coilovers - and again, it depends on your budget. KW Clubsport 2 Ways are around £2.3k which I read are very good, then from there there are Intrax which, new, with BT and ARC are over £4k. But brakes and suspension is where you need to spend the money in the first instance with an E92.

Another area you need to look is weight reduction. There's a LOT of weight to be saved by going from the standard seats to buckets. A full titanium exhaust system like an Akrapovic will drop 25kg and has the benefit of being fairly "tame" so you won't have noise issues on track.

Other weight such as the rear seats and rotational weight should be considered.

If you want a track car, why are you buying the most expensive? Surely you should be looking at the other end of the market - assuming you'll be pulling most of it apart anyway?
