So future plans for my car well dreams..... Spend as much time as i can doing track and drift days next year. And work on my driving skills and enjoy the car. I am starting to feel the car is lacking power especially at track days. It dose not scare me like it did. And adrenaline is fun
I have looked at the S/C kits that are out there. And the only one that gets close to what i would want is the stage 2 ESS kit. And i just cant afford that. I have looked at building my own using an eston m114 charger. But well S/C z4s has been done. And i dont want to build something you could buy. So i am drawn to the Turbo option or a n62 swap? But i quite like the m54 and it is know to be strong and reliable. So i think i will be sticking with it.
I need to address the harmonic crank dampener and the oil pump issue. I have a stand alone ECU lined up and waiting i just need more cash!!!
Then start fabricating a turbo set up. But with a twist... I am planing something and when ever i discuss it everyone says its crazy wont work and that i am a fool. So thats good reason to give it a go in my book. The idea is to use a variable geometry turbo but rear mount i. It will go under the floor where the standard back box lives. It will have its own oil tank and pump. Lag to the turbo is not as bigger a problem as you would think. Neither is pipe work back to the engine. The pipe work will be extruded aluminum basically heat sink. So there is no need for an intercooler as the charge will be cooled in the pipe. If the system is set up correctly they can be very responsive. Its been done lots in the gud ol US of A on big V8s.
I want more power for track driving when revs are higher. The car is not slow off the line anyway but it would be nice to have power coming in from 2.5-3k RPM most turbo cars have relatively small displacement engines and rely on the turbo for power. So lag is a much bigger problem.
The main advantage to this system is that i wont be worrying about under bonnet space or temperatures. Heat build up and soak are things people dont think enough about. And as i have said you would have to be bonkers to try it
If anyone wants to donate to help see this get done quicker i wont complain
