Thought I'd do a bit more of a clear and concise thread on my MPS since taking new photos today.

Specification so far:

Mazda 3 MPS Aero in Cosmic Blue
CP-E cat-less downpipe
Turbopacs custom built sports cat
CP-E catback exhaust system
Corksport SRI induction with turbo inlet pipe
Forge recirculation valve
Denso ITV22 iridium spark plugs
CP-E rear engine mount
Pirelli P-Zero Rosso tyres
MPS alloys sprayed gloss black
Mazda/MPS badges sprayed black
Clear rear fog light
Chrome/Amber front and rear indicator bulbs
Chrome/red foglight bulb for clear lense
White LED sidelight bulbs
MPS 'Extreme' bonnet graphics
Silver calipers with mazdaspeed logos
Removed sidestrips

On order/awaiting booking:

Sanspeed custom remap (24th September)
Bilstein B6 front and rear dampers (approx October delivery)

Future Plans:

4 wheel alignment (to be done after fitting of the new dampers)
DG Motorsport rear spoiler extension
Rays black wheel nuts
Mintex M1144 pads
Possible bonnet/bumper respray to remove stone chips
Powerflex exhaust mounts
Cobb gear knob
Cobb short shift setup
New numberplates (to remove all dealer logos etc)
New wiper blades

Photos:
























PS - the silver MPS is my brother's. He's got black wheels, new bridgestone tyres, cobb SRI induction, forge recirc valve, clear rear fog, black mazda badges and a race-pipe.

Just another quick update for those interested.
The car went to a local Mazda tuning specialist on Friday last week for a remap, which produced 305bhp and 320lb/ft.

But....the turbo broke (they're poor designs before a revised turbo was released in May 2008) and a crack in the downpipe appeared

So the turbo is being rebuilt with blueprinted turbo internals, and I've supplied a forge front mount intercooler and 2 step colder plugs. So in 10 days it should come back with around 340bhp and 360lb/ft.

Final update on this one:

Collected my car from sanspeed tonight. It's been there for two weeks after suffering a turbo hiccup during the remap it was originally there for.

During the two weeks I had a forge intercooler fitted, and the turbo was sent away to turbo dynamics and was blueprinted and had uprated internals fitted.

The end result after the map today was 318bhp and 340lb/ft. This is lower than I expected given the vast mods I have. Similarly modified mps's have produced 350bhp with the same mods, but I believe sanspeed now map more conservatively as they've begun to learn about the weak mps turbos. This is what their technician said after my first map, and what Graham also said to me today.

But even with 318bhp it goes like stink now and if I was offered another 30bhp I'd probably say no considering it's a 100% road going car only.

Graham suggested that the transmission loss calculations on the RR can be more accurately calculated by hand, and on that basis the car will be running between 320 and 330bhp on the public road. The best thing about it though is the length of the rev range that the car holds this power for. It's more than a split second peak on the graphs.

Many thanks to sanspeed. Excellent service from every member of staff I've spoken to.

Very nice indeed, what do you prefer the VXR or the MPS?

hmm that's a tricky one. Overall I suppose the MPS is the one I prefer. It's faster, better handling, more equipped and has better range of tuning options than the VXR, but I still prefer bigger cars, and the VXR was a nicer cruiser which could be turned into a beast quite easily when required.

Very nice. I nearly got a 3 MPS but opted for the Focus for the 5pot engine note. I was also told the 3 MPS is £400 a year road tax where as the ST is £245 iirc. I thought you sold the VXR to save money and you've spent a fortune on the MPS??

Ah that's a different story!

After the vectra I bought some cars and made profits on them, so between February and May I made £5000 cash. I bought the MPS for £10k, financed half of it and reduced my monthly finance by 2/3rds, as well as using some of the money to pay off some credit cards, freeing up money for mods!

The turbo blueprinting and fitting of the intercooler was free after the turbo failed whilst on the rollers. The tuning company I used did the above for free.

The existing US down pipe on the car cracked, so as a gesture of good will I got a lot of mods from the exhaust company in the states with a 35% discount, and the 2 grand exhaust system came with the car when I bought it, so been pretty lucky all in all.

That's including international delivery BUT not including import taxes and fitting. The turbo down-pipe is a 7 hour job. Approx £350 in labour at a minimum. Good job it was already on the car when I bought it!

Bl00dy hell!!! I hope it makes a BIG difference for that outlay. Changing the ST downpipe takes 10mins. The MPS isn't a cheap car to tune then?

Well I'm up on standard power by about 70bhp on a theoretical £3500ish. The exhaust and induction kit gave 24bhp over standard, the £500 remap took it to 45bhp over standard and a £760 intercooler added to that took it to 70bhp over standard.

Availability of parts is excellent. For every mod there's about 5 different companies to choose from. They're just all in the states or japan.

To give you an idea, Cobb Tuning make a gear knob specifically for the Mazda 3 mps that I love the look of. In English money it's £50 - not too bad. But then add £65 for delivery to the UK, then £35 import tax and that's the problem that arises.

The intercooler I just bought could have cost me £350 for a garret intercooler with custom piping in the US, but the import and shipping was far too much, so I had no choice but to buy the Forge Motorsport one for £760 from Forge in the UK.

Nice gains but tbh I'd leave it at that now. 300+bhp is more than enough for a road car.

I made that decision a while ago. When the turbo went away I had the option of uprating the internals to support 400+bhp but I declined and said I didn't want that. I was also offered the opportunity to pay £350 to have the fuel pump internals changed which would have allowed the car to be mapped to 350bhp but I declined again.

I've just fitted uprated front brakes and have Bilstein b6 dampers on order, 2 of which have arrived from Germany so far. So now it's all about harnessing the power I've got, not adding more

You can't beat the Bilstein Bounce as they used to say in the 70's. Very nice motor that.

After my experience with EBC i would have left them well alone. Some nice 6 pot brakes would be nice. AP do a set for the ST at about £2500 but they are MASSIVE stoppers.
For £2500 on an ST you can have between 310bhp-360bhp depending on the rolling road lottery. After that the ST turbo runs out of puff.
The Mountune kit offers a huge power band rather than big peak figure, which is why it's quicker than an RS in a drag. Sounds like the MPS lump has better tuning potential than the T5 engine though. Only a brave and rich man would dare run a pre 2009 ST much above 300bhp. Poor clutch, flywheel and weak driveshafts mean 1st gear lauching is a VERY risky business also. Is it true about the HUGE tax on the MPS??
