Make sure you do the shells.
500rwhp and puncture repaired tyres..... good luck to you.
A decent set of brakes WILL cost you 2k, and NO just a set of other beemer disks will not be good enough (BTW which other BMW will have good enough brakes for 500 rwhp?)
500rwhp is SERIOUS power.
It needs a lot of skill to contol but in the first place you need to get there. With your own limited skills and abilities you will have to take your car to someone to build it and map it, alone this will eat you budget in no time.
kind regards from another looser who changes tyres when they have a puncture.....(on his high powered car not the daily driver)
PS I agree with previous posters, try get it insured before you even start with the mods.
The 3.2 engine will need a lot of work to prepare this. Many have problems with the bottom bearings of the connecting rods. New correct bearing will be needed, and also ARP bolts.
For 500bhp, you will also need to reduce the compression, and use stronger connecting rods.
Doing less than 6k miles a year (and those miles rack up quickly if you like to drive fast) I spend around £400 on tyres every 3-4 months. About another £300 or so on fuel each month. Plus driving just a fairly standard car fast wears everything quick (clutch, brakes, driveline bearings etc etc).
My car costs just over £6k a year to keep on the road with spirited use (including fuel and servicing etc). If I had to pay M3 prices for some of the parts you could easily add a grand onto that.
Oh - I hope/think the OP meant that the people with puctures were getting the other three (still good ones) changed at the same time. So hopefully he's not using repaired tyres...
My honest advice would be not to start tuning cars with this approach. If your asking questions about whats needed for the engine and saying big brakes aren't necessary with big BHP I would say your not ready for this type/scale of a project. If your willing to chuck money at a car without a basic understanding of how it works your gonna end up a very frustrated man.
Advice previously given should really be heeded, we would all love to spend thousands and a weekend in our garages and at the end of it all have a car spitting out 600bhp and as reliable as it gets but its not that simple.
I thought I had a basic understanding of engines until I started a rebuild on a V8 with a carb and I'm on a very steep learning curve at the minute but to go all in guns blazing and try and turbo charge an M3 Evo without experience of any engine work let alone a BMW S52, is silly TBH!!
Start of small get an old Jap turbo and rebuild that so at least you can understand how a turbo system works and along the way you will learn about engines,cams etc
PS: for that kind of BHP your gonna need to get your gearbox and diff internals Cryo-treated, any idea what this costs let alone what it is?
Sorry my bad, didnt realise
why do this to an M3??? why not buy a cheeper 3 series with a 2.5 or similar and spend all that money on chassis and breaks and then a low blow setup? (well to start with)
as said whats the point in having power if you can't lay it down on the road. plus 4G wont get you far on an M3 but 7G on a 3G 3 series could build you one hell of a car!
i would strongly suggest you go and do some homework, understand about the extra strain this is going to put on the car, rear subframes, drive shafts etc and read other peoples real world experiences and build threads. work out what engines are best for boost. you can boost a car for less than what alot have quoted for parts above if you know what your doing. put in the research and you'll have a great car, reliable and fun.
For 500hp(+-450whp) you do not not have to build the engine because it can hold that power.
below are a few parts you will need for that power ,i am sure i have forgotten a few things.This are only the parts for the engine
-Turbo garrett gt30 or gt 35
-ARP con rod bolts
-ARP head studs
- +- 550cc injectors
-Walbro fuel pump
-Ecu tuning/stand alone tuning
-Intercooler + piping
-Oil feed + return lines
- And a lot of time
