Ok chaps, I'm changing direction on this for a while.
I'm not aborting the 350-400 project , just putting back for a while until I have sourced everything and made a final descision on which turbo assembly to complete the project.
Upon considering the options and what parts I have ready to use i'm going with a revised route .
I'm going to go on with rebuilding the K03/4 parts I acquired from Beardy matt , nothing close to 350 -400 , more 300-325 ish for now, utilize the FMIC and parts and fit it all to my current fitted BUL engine.
Having thought about it, the old bus is already at 270 , so fitting the uprated turbo and few parts will not be that excessive and will at least give me something to show for it all, I just hate sitting on project parts and them not being used, waiting to get the big figure project completed will just end up taking longer than I want to wait now.
I'll get it done but i'd rather have all the bits here in one go then go for it rather than it dragging on .
So its onwards for a few more ponies at least, better than zippo for the moment.
I need to get to the bottom of these random epc issues while i'm at it .
