Nice to meet you to Mick!!!

yeah I got caught in the act of buying all this.......... cos racecar!!!

and thought it might be an idea to buy a surge tank whilst I was getting other bits and pieces.

lets just say I'll be eating cardboard for the next few weeks!!!

hopefully have almost sorted out the boost issues will finish putting in the new solenoids tomorrow and test her out!!! :)

ended up replacing the whole blackbox of 7 solenoids and 2 green solenoids as one was brittle and broke and I now have pressure in the vacuum system!!! but I'm still not getting secondary boost so first point of call is to check I'm getting vacuum in the vacuum system (separate from the pressure side of the vacuum system)

The system is so complex its a challenge to get my head around it.
The turbo control solenoid uses both vacuum and pressure to operate properly, if not then it wont transition effectively. so I need to see if the "charge control actuator" and the "turbo control actuator" are moving then it means I have vacuum and the solenoid is faulty. The charge control solenoid was in the blackbox so that should be fine! so if that's working correctly I'll see the "double throttle control" actuator moving also.

so much to check and make sure its operating correctly but I'm happy I'm getting on top of it!!!

here are a couple of pic's to show the head f*ck LOL

That's the thing Brett apparently a twin turbo FD with 280kw will blow any single turbo FD away even if it has 400+kw and some guys are pushing 345kw (537nm @ 5200rpm) out of the twins.

So if I get all the vacuum system and solenoids replaced which I'm over halfway already with fault finding then it'll be good for another 12-15years (and with a vented bonnet maybe longer as there isn't as much heat in the engine bay.)

You hear so many different stories and people are trying to push there own parts ETC but apparently all the FD race stuff ie: Spirit R or Bathurst R are the best items with the least problems but then some guys swear by the single turbo setups.

Its hard to know what's right or wrong so it comes down to personal preference I guess.

    • You very likely need to get it on a dyno and tune it. My assumption is, you've got an RB25DET tune in it, which has a different manifold, different injectors, and different cams as a minimum. What O2 sensor are you running?   When you say it runs extremely rich from idle all the way to redline, is this just free revving it you see that?
    • I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.  
    • I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.
    • Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.
    • Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...
