Paul.....both

Dave.....glad you enjoyed it mate ....it is a little on the evil side, and you can't help smiling from whichever seat your in.

I am afraid in my quest for "Mo Farrah" av gon an blawn me terbo ..... my boost had been set way too high and the bearing could not cope, so I think I might have to detune my engine until I can build a more robust set up.
Tub is beyond repair as compressor wheel is damaged, so I bit the bullet and ordered a chinese copy as there is no way I can afford even a reconned tub, came yesterday so I will get some pics of it up later.

Can you get high capacity/high pressure oil pump for that engine,if not shim relief valve for a bit more oil pressure to feed turbo and rest of engine better.

Turbo's fail because people never let them spool down after hard driving and it was probably well used prior to you,bit of a bugger after all the graft

Rebuild kits are available but would you trust something that's got to run at silly revs and heat without being set up properly, No.

I have a nest of new turbo`s here Kev. They came in a job lot of other kit. I will take some pics and if there is anything you fancy let me know.

Awesome Bob might be handy to have a spare
Paul....it was a rebuild by me bud but I think I pushed my luck way too far, I always idled it down tho.....when you say shim it I'm guessing that would be a smaller hole on the return that would increase the pressure around the journals, but I suppose the risk there would be oil seals, they would be needing to be the uprated staggered type

[flyerncle]

Find the relief valve,there should be either a plunger or ball with a spring behind it and this relieves the oil pressure by bypassing it,if you increase the spring tension you increase the oil pressure as it takes more to lift relief valve,oil seals should be ok as the increase is not forced against the seals to any degree they just seal the crank/cam etc against the oil floating about in the head etc (if you get my drift)

I have just had a quick look and there are about 10 of them, 4 brand new t4`s a couple of new take offs that are t3`s and a lot of second hand smaller ones probably from 2ltr ish engines.
