darrenjlobb's Project M-TDI Twin Turbo Supercharged Derv Bus

Hopefully FCS next year?

As for build costs, I dont really keep a running total, but bear in mind I do all the work (well 90%) myself, so its only really parts and welding supplys etc that go into the costs...

Small update,

Have just pulled the motor out again this afternoon, Ive been running it at 25 psi for the last few weeks, and it goes ok (some have seen video can vouch) but obviously 25psi and mild tune is far from my idea of ideal....But I am literally hitting the limits of the head, I cant crank the boost because it floats valves (pis weak valve springs) and cant rev it any harder (im ditching lifters at 6200rpm) so have decided to pull the motor, and give the head a good beef up, so bigger valves, solid lifters, re ground cam for more lift / to match the lifter life ramp, some serious porting (hdi16 heads are tragic!) and some other small modifications....which should allow me to open the sucker up!

I am also fitting a new primary turbo to the setup while its apart, as after some calculations, the current setup will hit its efficiancy peak before I want it to, so upgrading the current 2256v primary to a GTB2260VK, which when in peak flow in compound with the big wg turbo, should move a serious ammount of air, just what I need!

Did a video, although there has been an epic editing fail hence the size of it, but theres a time lapse half way through, which was my first attempt at one, so hasnt worked out to well as didnt set camera to take picture often enough etc, and the res is useless due to free software!

Getting it out was a bit more of a ballache than the average change out, as i didnt want to have to pull the manifold off as its a total farce to do, but you cant remove the tranny mount without taking it off, so some grinding / drilling via wheel arch was needed, and will weld up the mount so that in future it can be bolted externally, removing the need to do it from inside which is imposible with a pair of turbos in the way!

Some photos i took on the way out:

Few hammers / grinders and man handling later:

And a video with time lapse, albeit a bit fail!
