Theres a couple of choices mate depending on what you need it for??
A limited offer at the moment is £1000+ vat fitted and mapped for a g4 atom witch is a very good upgrade for an rs turbo or similar and the g4 storm with built in 4 bar map sensor and loads of other features good enough to run any spec cossie etc is £1250+vat fitted with custom loom to your car and mapped+whatever parts you may need like coil pack and leads for the wasted spark etc...

well the last couple of weeks have been eventfull, luke managed to get the link ecu fitted which solved the miss fire problems and basicly change the whole running of the car, so he set about mapping. to cut a long story short i fitted a pre turbo oil filter which has turned out to be a big mistake!!!!
the filter blocked and starved the turbo of oil over heating and snapping the sharft so of it goes to cr's for a rebuild!
i was really looking forward to driving her home yesterday but i guess i'll just have to wait.

id never fit one of those turbo filters anyway, ford never used them so i dont see why fitting them now would help, touch wood you get it sorted soon pal and see some good figures

the restrictor would be long gone though, even if its not having an adverse effect on performance

blockage was caused by alloy fileings the only thing i can think of is the new inlet cam bedding in on the cam caps or because it was a 4x4 cam with spacer! the thing is the bits of alloy was so small it wouldn't have caused a problem to the turbo so kind of wish i hadn't of fitted the filter now.
chins up any how and trust luke to do an outstanding job he showed me the figures before the turbo gave up and they looked wicked, nearly 200ft lbs at 2000rpm boosting hard at 3500rpm and he still had some tinkering to do says he'll get it better than that.
just a bit gutted cos i had planned a round trip to see the boys this weekend to show her off hopefully next weekend

The oil pressure is a little low too so we are going to give it a quick check over but as said it doesnt take long to clog the turbo pre filters and should have been checked/cleaned after the last running in oil change..
The car was doing well just before the turbo let go,2.5 bar of boost by 4050 rpm and 420lb ft and this was well before the ignition map and afrs were optimised so my original fig of 450/450 might still be on?
It wont take long to whip the sump off and check theres no excess wear anywhere,then chuck it back in a re fit the rebuilt turbo and finish the map..

Any thing that filter catches would have done the turbo no good, especially if its a roller bearing turbo.

We drained the oil from the engine and it was as clean as a whistle so then put fresh oil in and done an independent oil pressure check to reveal only 50 psi at revs so said a check over with sump off was needed..
As soon as i saw all the shit in the gauze i knew there must be problems but in all fairness the engine sounded sweet!!

As soon as the turbo went it was the first place we looked and took photos as soon as we split it in half and there was a lot of unmagnetic fillings in there..

The owner and his dad built the engine and it seems strong but need to work out where the shit has come from..
Where there smoke theres fire!!and where there debris in the main oil gallery theres always damage or wear somewhere...

I wondered if the block has had some machining and the gallery hadnt been cleaned out and a new ball bearing put in but luke has asked the questions..

If the turbo feed is from the head oil has more or less been around the engine with a gallery to the head, round part of the head and into the turbo, plenty of opportunity to fill the pre filter.
The worry is where its come from, a dirty build (bottom end) would be iron filings, a dirty head build would be aluminium (if the head has been faced or ported?), is the oil pump aluminium on the YB?
Dirty engine builds are the primary cause of early engine failure, bearing wear is first apparent with low oil pressure, knocking with severe wear.
I suspect, oil pump (if its ali), head swarf or wear (if the cams run direct in the head), swarf is bad either way.
Hope its nothing too major mate as it sounds like it was making really good progress!

existing shells/bearings were used as they had hardly seen any use the only reason the engine was stripped was to fix the key way on the crank.
pistons had cut outs while it was stripped but these were checked and cleaned
