I've seen a lot of threads where someone eventually posts concerns about longevity of their car with certain mods. I think there should be (and I searched) a place for this info for reference. Most of the posts with mileage responses are outdated anyway.... like from when R53s were still under warranty .

anyway... maybe a format is in order

current mileage
mods
mileage mods were performed

IDK, but the more info and accuracy the better this will be for reference...

Thanks!

 

First thought you meant gas mileage..anyways

All mods done around 64k
15% pulley w new belt
Royal purple oil
Cold plugs, msd wires and coil
Alta v2

Put a few thousand miles on the car since mods including a 2k mile road trip from Ohio to the east coast and back. Don't have long term results but can say the car overall runs smoother with mods and oil maintenance done

Hopefully a few others will respond with longer history of mods..

On the mpg subject I am getting better than before even though I feel like I drive the car a bit harder because it begs for it. 27city/hwy combo and nearly 35mpg average on road trip!

 

I don't want to highjack your thread but I would be curious to know the highest mileage modded mini vs stock mini on nam...

Anyone?

 

One of the White Roof Radio guys is over 200k in a modded MINI.

 

110K

CAI
Alta 15% Pulley
OCC
Denso spark plugs nad 8.5MM wires
Alta Air Diverter
SuperSprint Exhaust with BMP Tips
ProMini Adjustable Rear Control Arms
(Just got some Alta lowering springs!)

Everything was put on around 100K. The exhaust and pulley I'm not to sure about because I bought it used!

 

Sitting at 95k Miles right now.

Alta OCC: 45k
Alta CAI: 45k
15% Pulley: 65k
Milltek: 65k
MSD Ign w/ Kings wires w/ brisk plugs: 65k

Been changing w/ Redline every 5-6k miles.

Stock original clutch, and S/C, and axles.

 

93k now
royal purple oil (from 80K-present, prior was castrol syntec 10w30)\
alta OCC &CAI 62k miles
alta v2 15% pulley 71k miles
ATI superdamper crank pulley 80k miles
clutchmasters stage II clutch and alum flywheel 83k miles
obx headers with pace setter high flow metalic core cat 78k miles
detroit tuned bpv 69k miles
vacuum gain system 87k miles
BBS cv 17x7.5 et 35 wheels 82k miles
alta 19mm rear sway bar 82 k miles
colder plugs 85k miles

generally get around 26-28. but it could be a LOT better as I'm running super rich. ( my donut gasket leaks just before the cat allowing oxygen in as it creates a small vacuum and pulls air in.. the post cat O2 sensor reads it as the car running lean and has thus thrown several lean codes and is causing the car to run super rich.... kinda gay.. but i need to find a shop i trust to do the exhaust right this time, as last time i took it in i asked them to weld in a braided flex pipe and take out the donut and they didn't....)

 

I have 03 MCS
M7 16% Pulley
M7 Intercooler
Alta v2 CAI
Alta 19mm rear sway bar
Detroit BPV
JCW 380cc fuel injections
JCW suspension
Invidia Cat-back system
Dinan Front Strut bar
Helix camber plate
GIAC
All the parts was install after 123K miles. some of the parts was new and some was used.

 

also curious, this is going well so far. This, I think, is very useful info for folks looking at mods, maybe it will end the "will this mod destroy my mini?" posts...

keep it going!

i'd add my data but it's useless as i just not my R53 a couple weeks ago and it only got it's DDMworks intake last week...

 

what mileage are you at now?

 

This site has some problems.

 

I have 156k the mods have been on since 28k. I'm still on the original supercharger and no major components have failed. Mods are in my sig.
