I was looking at 550-650cc injectors but these were offered at a fair price, so I jumped on it. The car will then be tuned to the maximum psi awailable which is somewhere in the range of 22-25psi. Im not sure if I will ever reach the 800hp/900nm range though, but the bottom end sure can take that kind of numbers since its all forged. Im hoping for 600-650ish at max boost and probably 700nm max. The turbos Im running are quite small (GT2252's) and Im not looking for explosive power, since the car is both a daily driver and a weekend racer (tracks and not strips).

Some offtopic.....

here are both cars in one of the F1 garage at SPA,,,,, (my BT is just posing ) 4th or 5th of May 2009 ,,, the British MLR club had a trackday

And this M3 GT twinturbo is an unbeliveble fast car



IF Sveinn would please give us a link ,, to watch how fast we picked up M3 E46 and other cars,,

I hope the injectors will give my BT some extra gain for my future setup,,thinking of T28 and 1.2 BAR

the oem injectors are 360 cc

I am no TURBO genius,, but as far as i have searched the new version of T28 is almost the same in size as the ALPINA T25
GTt25 is also an option

the M3 GT Sveinn owns is on 12 psi normaly but can go to 22 psi and that is almost 1.5 BAR on GTt22 turbos,,, and belive me ,, there are few cars out there that can keep up with HULK

they are not the same size or even close, that m3 has a decent spec but nothing special so the name hulk is connected with incredible and with due respect that car is not incredible...and if you go for gt25 you better change some internals or you will have a f u c k e d engine as two people already tried and learned, you will still need to put a lot of money in and a good engineer to get everything perfect.... SPEED COSTS MONEY HOW FAST DO YOU WANT TO GO................THERE ARE NO CHEAP SHORT CUTS ON A BT........

Hulk is just the nickname because of the color of the car

not that your opinion matters to me mate, but there is not much I can do with the car in addition to what has already been done if I want to keep it street legal and fully TUeV'd. Incredible or not, there are not many cars like it around. The nickname "HULK" is something that Sveinbjörn and our common friend came up with and relates to the colour.

may be there are not many cars like yours in lux agreed, but in the rest of europe theres plenty, already said your car has good spec i havent slagged it off, theres dozens of cars like yours being driven round london with silly amounts of bhp and torque with twin turbo conversions and are street legal, so it does not even make it special, may be for a small country like lux it is....

Please point out all of these turbo or biturbo M3's you have over there, I seem to have missed them, I have not come across many in Germany also, or Belgium, I know of one beeing built in UK (by a friend of mine) and another one in Holland. There are a fiew Turbo M3's up in Sweden. As far as I know My M3 is the only TUeV'd Turbo M3, or that I was told by TUeV. I have still not come across another BMW with ceramic brakes though.

There are also a fiew Turbo M3's in Poland, one of them is owned by a guy I know, (Chris the dentist).

Please send me some links to these cars, I will enjoy getting up to date with what is happening in the BMW Turbo world in UK. Seems you guys are way ahead of us here on the mainland.
