I know this is going to sound really basic (and I'll be shot down for it) but you haven't installed the turbo the wrong way round have you? (is that even possible?)
It could be something that's staring you in the face (maybe the firing order of the engine is wrong or something) that means you're literally looking past it to find the issue when it's actually staring you in the face.
(sorry - i know it's terrible idea but nevethless, thought I'd offer it up).

For those of you missing the videos... I have less idea about YouTube and things than I do about building turbo v8s. And looking at the way this threads gone. I've not got much idea about that haha.
The last video is just a look round the inlet manifold with it pressurised. With tons of bubbles blowing out of everywere (from the soapy water)... Oh and me breathing a bit like Darth Vader due to some wierd chest infection curse word I seem to have going on..
Il try and figure out what crack is and reupload it..

That been said I have checked everything haha. It's looking like the boost leak is the issue but il know for definite when the new gaskets turn up (and I spend hours stripping and rebuilding the inlet).. But honestly until the boost leaks were found last night, I was open to every suggestion! Cheers |

Just checked the videos and they play perfect from my gallery, yet any I filmed myself (I didn't film the burnout vid) don't play even for me on YouTube.
Not sure what's going on there tbh. Technology isn't my strong point. Il delete them and reupload see if that fixes it (my dodgy Chinese phone is probably blocked from YouTube or summat haha)

So bit of an update to say well... Not much of an update.. got my new inlet manifold gaskets last Friday. Then it decided to chuck it down Friday night and Saturday.. busy adulting Sunday and Monday then back to work  Hoped to crack on last night but swmbo has decided on top of the new staircase, were having a new kitchen. And by time kitchen people had gone last night it was well and truly dark... Then to mix it up tonight, we've had torrential end of the world rain! Not a happy mat. Fingers crossed the weather is looking marginally better tomorrow and Friday so if I can il pull the inlet off tomorrow night and refit it Friday if I can't finish the job I'm also going to have to attempt to do summat with the garage so I can get the car back in. Cus at this rate it will be next spring by time I get some decent weather to work on it! Did do something mildly fun at the weekend. Took my mate to pick summat fun up for his ls400 (what did he say about me being a bad influence).. il wait for him to do the big reveal on that tho. Anyways. Enough waffle for now. Il try and get summat more productive done soon. Cheers |

Gah. Was really looking forward to your post saying that you had boost! Any more of the family time getting in the way and I think we’ll all have to chip in for a baby sitter for you. Good luck with the weather anyway. Oh, when are the new wheels going on? I finally got my set on the other day.  |

Good luck with the weather anyway. Oh, when are the new wheels going on? I finally got my set on the other day. Sadly not.. as much as I'd like to say I've found it, it's still missing. Very very missing (much like the charge in the battery)... I never thought of that, if I set a go fund me up to pay for a baby sitter I'm sure we could scrape enough together for me to try and maybe finish it maybe... Haha And the wheels are a touchy subject, originally I said I couldn't fit them until the btcc kit was on, as there too wide for stock arches, and I couldn't fit the bodykit til the exhaust came out the back.. and I couldn't do the exhaust until... Well you get the idea... Yours look really nice tbf (price of mine reflects the condition, don't think they were ever cleaned on the back), I've been thinking about colour and I'm sort of torn between an anthracite colour, or gloss black. Funnily enough local wheel firm has an offer on at minute so may get them refurbed and fitted, if nothing else just to get them out the garage so I've some room. Cheers |

So finally managed to catch a break today and made a bit of progress... After a day working in the most horrendous place you've ever been in (think loft insulation on steroids. I came home with my arms covered in rash and itching like a itchy thing) the sensible thing to do would be a bath and a quiet night once kids are down. However that doesn't get the lexarse built. So best crack on.. First up the gaskets. These are the lower intake to head gaskets. Pictured for no other reason except that if I ever need any more I've got the part numbers.  Stripped a bit of wiring off to get some access. And whipped the throttle body boost pipe off. It's held on with 10 nuts/bolts. The centre 2 bolts are basically hidden, the next 4 out are visible but under the fuel rails and upper inlet, the outer 4 are there. Just a smidge awquard. Tbh I don't think your meant to be able to take the lower inlet off without first removing the upper and fuel rails. But that means disturbing fuel system that's all fuel tight, plus a load more work. And we don't like that. Using just about every combination of 1/4 drive tackle I'd got in my box, plus some very choice words and a bit of lateral thinking after 30/40 minute or so we were here.. it was also well on its way to going dark so the lamp came out of retirement too.. (excuse the terrible photos, the latest swim in the oil drain tray hasn't done my phone camera any good, there's a new Cheap special on the way, this has done 2 years hard service anyways)..   The gaskets are a multilayer affair, and the layers had started to come apart. Plus if I'm completely honest. I didn't do a very good job of cleaning the mating face of the head up and hoped the instant gasket would do the job (it didn't, sloppy plant fitter quirk there).. Spent a good while cleaning both the mating face of the fanimold and the head up. Stanley blade, some Emery paper and finally a 150 grit disc wrapped round a block to finish off. Then washed down with about 3 gallon of brake cleaner. Started to reassemble starting with new gaskets on   Finally after another hour or so, here it is all back together.. all torqued down and fingers crossed fixed. Maybe hopefully..  Whipped the battery off to take it to work tomorrow to bung on our hefty charger. It's unlikely it will "fix" it but it may perk it up to get a few starts out of it (it's fine when it's been run and starts every time after the initial start). Think it will ultimately end up in the boot with a big battery and some 0awg cable up to the front. Hopefully if tomorrow goes to plan. I've some adulting to do on my way home from work but assuming I've got time it's getting a test drive. I'm going on holiday next week (first time with 2 kids, may not be that relaxing  ) and I want to know either way before I go.. If it's fixed the issue I can go away with my smug face knowing I just need to bung a new wastegate on and it can go back for some proper mapping.. and if it's not fixed, I can go away and forget about the hateful bag of Japanese wibblepoo and ponder what vw diesel I ought to be driving  haha Fingers crossed for a proper update tomorrow. I've also decided that's the last "job" I'm doing outside in the dark.. I've got a garage I can't get in for stuff and end up working on the drive in torch light. So before I do anything else I'm going to have to come up with a plan to store some of my "stuff" so I can get the car in the garage to work on it Cheers |

So it's a sad day in mat towers.. partly because I'm back off holiday back to reality and back to tradesmen doing there best to bankrupt me with the quotes for a kitchen and staircase. And partly because last Friday the test drive happened and we'll.... My boost... Still missing... I tell a lie, it tried to make an appearance. But only tried.. Got it all back together, straight home from work and jumped in. Fired up, sounded the same. Pulled out my road onto my "private road" for a test drive.. 1st 2nd 3rd still no more than 3psi.. in 4th gear if your really loading it up just a split second before the limiter it starts to wake up, the gauge indicated around 5 psi just as it hit the limiter. The problem being the limiter in 4th is well into ban territory which makes in no use on the road.. If I put it in 4th and slipped the clutch a smidge to get it to build boost it sorta worked before a lot of magic smoke flooded the car and I lost the pedal for a moment or two til the clutch had cooled off.. feeling positively curse word off with the whole thing I came home parked it up and sulked. My mate told me to stop being a dramatic princess and there "must be something I'd missed" so he'd come and have a look with me Friday night... So we spent 3 hours going through everything I'd done.. and the result was..... Everything is perfect. I've a couple of tiny tiny tiny miniscule boost leaks, but only when I cranked it up to 20psi!!! So that's not my issue. Finally far later in the evening than I really wanted to be spannering in the dark, this happened. Turbo is off!  Checked the turbo it's all perfect no play, no damage, no snapped shaft, it's all as I'd expect for a 100 mile old turbo. I know it was said a bit back it was too big, and I was adamanent it wasnt. But it looks like the 25cm exhaust housing is too much for a stock engine with stock rev limit. As much as I can set the rev limiter anywhere I fancy I don't really want to be revving it harder than stock or it won't last. Plus realistically what use is a road car that doesn't do anything until 5k rpm. I'm not wanting to be like a modern diesel on full boost by 1500rpm. But some midrange would be helpful.. So with my dummy fully out and the car back in bits I went on holiday for the week.. alsorts of plans in my head. Get a hx40, get a smaller exhaust housing and matching turbine etc etc. Possibly look at a few of the smaller borgwarners etc. Then one night after a couple of Shandy's I went on eBay. And now I have a gt35 ish size Wuhan war whistle on the way It's not going to be the 800bhp capable monster that the hx50 was, and it's probably not going to be same quality.. but least it should work (same T4 flange, 3 inch vband on exhaust side) obviously it's not going to be a direct swap since my downpipe is 4 inch, oil feed and return will be different.. but it shouldn't be a million miles off.. Anyways. Yeah. That's were I'm at, soon as it arrives wel have a gander what the quality is like and get the damn thing on. Til then il spend my free time looking at kitchen brochures and seeing how best I can hang on to my hard earned.. More soon hopefully, and sorry it's not the update we all wanted. Cheers |

An update is still an update  Is there no that many interchangeable exhaust housings for the turbo you have? Or are the smaller housings different flange fitment? |

The hx50 can come with a a 16/18/25cm whatever housing. It's that there aren't many about used and by time I've bought new plus the bits to swap inside and had it rebalanced etc. I may aswell chuck a Ching Chang spinny thang on it and see what happens. Plus John the mapper has said hel buy my hx50 if I can't get on with it for one of his ls builds. So everyone's happy (well except me haha) |

There's always the nitrous option if more go is required  |

There's always the nitrous option if more go is required I ran nitrous on my vauxhall swapped mini when I was a young un.. as hillarious as it was (75bhp shot on a 120bhp engine in a 1968 mini).. the constant bottle filling soon got tiring. As much as I know it would help spool it, I don't want the aggro.. The new turbo that's coming isn't "small" it's just smaller than the one that's on haha. It will still have enough for 500+bhp I'd imagine. Which ought to be enough on a road car. Maybe. Possibly. Well see |
