The build is finally done! :cartel::cartel::cartel:
This build turned to be more than we bargained for. Nothing we have done before fitted thus the new approach.
It all started 6 billet blocks of 304 SS. Machined for a perfect fit into the block reassesses. Thicker flanges than usual followed to ensure there is zero flex after the welding. The first attempt at a bottom mount did not go well. The turbine housing was a little too large. Moving the turbo forward or backward proved useless despite the Z4's ample engine bay. We were left with only one other option. Top mount. I never liked the top mount approach it just seemed untidy to me. However, given power goals and the resulting turbo choice, the top mount was my only option. My biggest concern with the top mount is how close the exhaust housing sat next to the engine cover. This was a major issue for me as I refuse to run to the car without the cover. The only other option is to move the turbo forward at the expense of a filter. So be it. (I am working with a local company to fabricate a custom filter and carbon fiber housing but this will take time). Once the SS fabrication was completed the car was transported to the FR&R HQ to be pieced back together and custom aluminium feed and drain lines/pipes. I managed to pay the guys at ATS a visit for as much heat shielding as possible. I am a big fan of the Thermotech Micro Louvre Air Shield. After wrapping the manifold with heat wrap and double wrapping the downpipe, a turbo blanket was fitted to the exhaust housing. The Air Shield was then molded over the exhaust housing and downpipe to ensure the under hood temps are kept in check. The turbo was then fitted with a turbo guard. After an oil service and coolant change, the car burst into life!
After a quick firmware update and a canned flash, we were ready to start testing. The idles like a stock car even at cold start. Leaving the suspension setting in Normal and the gearbox in D it feels and sounds like a stock turbo car. Flexing the big toe a little is greeted with jet like turbo spool symphony. Planting the noise pedal ups the decibel count 10 fold. With the roof down the sounds are fantastic!!! Brings back memories off my first drive in the ST 335i. This time around the boost feels so much linear and the response is so much better thanks to the dual ball bearing setup.
I am currently evaluating what are the limits of pump fuel is to decide what wastegate spring will go in next. Once that is done, the fuel system upgrades will be fitted. Right now I am enjoying the car too much to chase power records. I honestly feel 600whp will be enough for now. That's the goal for 2016.
A massive shout out to the Nishen and the TMSS team for their hard work and expertise! Both the TMSS and FR&R teams are experts in removing and installing the Z4 subframe!
Pictures and videos to follow soon.

@Gav there is only one other Z4 with an ST and it's LHD(that I am aware off). I have looked for the last few months and managed to find one running a Motiv kit. This just might be the first RHD ST.
Pictures to follow soon. Busy in Swartklip atm. Will be back in the land of the living later this week. Will try and fit the new wastegate spring this week. Can't wait to Run with Fsalie and Girevik77 once I'm done. 18 cylinders, 1800whp, 3 screamer pipes!!!

Me too, and I honestly feel these people are not getting the props they deserve. Some of the stuff they are doing are firsts in Africa. I want to do a single in Durban, but here they might tell me to put Dicktator
Amazing, must feel like a rocket ship.

Is 550whp on pump fuel only?
