  1. Why have you said its in perfect condition then?
  2. No problem mate. Pleasure to deal with you!
  3. That is not how a MAF works. Its where it is for a reason
  4. Well it should be noted that this was an issue when my engine failed. I had never really done alot of miles in my car from i bought it and it had a shady history at best before I did. My engine needed rebuilt after a mechanic doing some work made a bit of a silly mistake with it. And my main bearing caps were removed for inspection. After that was when my crank seized although not whilst running thank god! Since my engine has been rebuilt (with clevite bearings from whifbitz i may add), I have had no issues whatsoever. My engine makes 9 or 10bar oil pressure on cold start up (im told) and has no issues at all. I've done a little over 1000miles with it now running wastegate pressure at 0.6bar and it just keeps getting better and better - not to sound smug!
  5. This happened with mine when my engine was sent to be dismantled. The crank was seized in the block. It wouldn't turn even with a 3 ft bar on the crank nut. It was apparently due to the big end bearing caps being installed incorrectly some were super tight on the crank and others were loose as a goose. Could be the reason your bearings have failed..... i guess, I am no expert on that but something to think about. Maybe someone more knowledgeable could shed a bit more light on that particular scenario.
  6. If you could get that in writing from clevite themselves you would have a strong case to return to your engine builder with
  7. I wonder how does that map to what he was supplied with.
  8. At least if you can confirm that the correct bearings were supplied under license from clevite you have a case to go back to your builder/machine shop (if they are indeed the same), but having been down this road myself in a similar situation i can foresee their immediate response. Could get very difficult for you! Such a shame you are having no luck with this car at all mate
  9. That has pretty serious implications for Whifbitz if that is the case! Infact its heinous! I think you need to get to the bottom of this with them or clevite immediately! Have you made enquiries with Paul at Whifbitz or Clevite themselves?
  10. Sadly I agree that appears to be the case all too often with these things. Ive never heard of any engine builder or mechanic standing over this sort of work unless forced or taken through the courts!
  11. Do you suspect that the bearings you were sold are not infact clevite bearings?
  12. In my experience no engine builder or machine shop will rarely ever stand over work like this if something fails. There's always someone or something else to blame!
  13. Yea, having never owned a VVTI I don't know much about that end of things in detail but would be interested to hear the theory behind it!
  14. Why are other brands of cam any noisier than an HKS set? I've never heard of this before?

    Getrag Dilema

    Punching the values into that gear ratio calculator thats on the forum it looks like the values I see on my car are accurate and then using the V161, at 72mph you would see 3000rpm in 6th

    Getrag Dilema

    I have a V160 coupled with a B04D (UK Auto), I find it provides great acceleration and it holds a nice balance on a back road for swinging on and off boost but on the cruise say at 70 odd mph it revs about 3000rpm in 5th which to me is a little high but dropping into 6th will drop to about 2500rpm
  17. Ah ok, no experience personally so just wondering, havent heard of them being used widely just. Will this be one of the Gen2 ones?
  18. Is the intercooler not savable or do you think you'll just replace just to be on the safe side?
  19. Is a 6870 not a bit of a big turbo for a road car mate?

  21. Is that sitting on top of the bottom edge or clipped into it? Looks like the bumper itself is pushed down?
  22. I'm using one mate, works pretty much like a stocker. Bit sharper in the low gears but down to practice in my opinion. Pedal feel is like stock, nice and smooth, very little rattle out of it ever.
  23. Lol fair enough. Remember mine is only doing 0.6bar on the wastegate spring there lol im sure it will be much more lively at 1.8bar!
  24. Im surprised the videos haven't made it up here yet!lol
