No dramas mudmonkey and Simon that's a very good point it could be defective like you say the insert inserted too far thus restricted the airflow mmmbi shall have to try a new top let you all know soon thanks aswell for everyone's input

Didn't realise it was the front screen sorry yeah as chadler said it's no good for that sorry

The hoses being used are the standard landrover ones so I think there all 2 and half inch hoses so I can't see why it wouldn't work as everyone else uses standard hoses and it all works for them, and the airbox I have came with a reducer standard as one fits the standard hoses amd the other end had a reducer to fit the turbo end

I don't know but as soon as I take the hat off the top hose doesn't collapes and I get full boost everyone I have spoke to have been baffled too as most people have the same / similar snorkel but it could be down to the smaller airbox I have but even when I wasn't running a airfilter at all it still done it it was snorkel straight to turbo still top hose collapses so I really don't know there is no blockages anywhere

Yeah I would say around 6 inches and no engines a conversion and I'm running the cylinder airbox although I noticed there is too sizes and I have the smaller one I do have the larger cylinder one but I cannot get it to fit as the size of the hoses to be attached is 3 inch so I need reducers if I am to use it

Here's top

Here's the underside

Bother the link doesn't like working basically it's heated window repair kit you can get it from most motor factors and halfor d

The rust shouldn't make that much of a difference but if you are concerned gently remove rust and if a track gets damaged whilst removing the rust use http://www.halfords.com/motoring/garage-equipment/auto-electrical-supplies/granville-rear-heater-repair to fix it

Hey all resolved issue some how the snorkel hat has restricted the airflow that much it cause all the problems take the hat off and I get full boost so I'm wondering how much I have to butcher up the hat to get enough air flow it's a bit messed up though as it is a bearmach snorkel so I wouldn't expect it to restrict the air flow

Ha ha ha nope I'm going to try a larger airbox off a 300tdi see of that changes it if not il just have to make a new top hat for the snorkel maybe a bigger one as the pipe itself isn't restricting it

I always thought they had to be in top hose as that is usually the pipe that gets hottest first I would probably say it must be the switch or as disco Ron said a airlock

Hello lads found the problem! Its with the airbox basically if I take the end of the cylinder off and drive it works so it's got to be between the snorkel and the airbox but I'm confused as I renewed the hose that comes from the side the snorkel comes from so that must mean the snorkel piping must be too small but it's made by bearmach so who knows

Jad I have had so much enjoyment out of seeing what you have done it's very impressive so glad I only just came across this post so I could get all the way to the nearly finished project good luck look forward to seeing it all work

Hello mate there not really worth repairing as they are so think and frankly quite carp quality but if you were going to tackle them I would go down the fibre glass route

And yes no egr

Bottom hose is all metal until the intercooler which has a silicone 90 hose on it and the same at the turbo end but I will check that! Also what would happen if I replaced the top hose with a metal one then it can't collapse,

Hello boydie thanks for the reply I hope the turbo isn't dead as it's a brand new one well re con, yes filter is new but I might have to double check intercooler as I did flush it out with very potent stripper but that was it really so will re flush and see what happens thing is it done exactly the same thing with the old turbo which I thought it was that so replaced it but will let you know thanks

Hello all, il try to explain this, basically the defender runs lovely and works fine until I try to really open it up on a dual carriageway as soon as I do I get a ploom of black smoke and lose power this is due to the top intercooler hose collapsing in on itself now I have put a new hose in there and still no luck, but I am confused as to why it collapses in on itself as you can see before it does that the pipe is expanding to indicate boost but then it just suddenly crushes in like it's lost all boost also forgot to mention it's got a brand new turbo as this issue was here before hand any ideas anyone?

I done this same conversion on my 90 just stuck with the lt 77 and just cut a section out the housing moved a dowl and fitted the 300tdi gasket to the box and it works like a dream I'm not 100 % on the dowl though as my doner was a auto ah also had to change the fuel pump my 200tdi as the fly by wire clearly wouldn't work

I just removed the arm from the disco steering box (with alot of patience as it had to be pulled with a puller and just popped off over night) and put the defender one on as you can get defender steering arms at pretty much every offroad event but ad said above that's whats required

For everyone out there wanting to know if a 200tdi pump fits a 300tdi and works the answer is.. YES it does have recently brought a 300tdi disco so I could use the engine for my defender as my 200tdi have some rather large (2mm) scores in the bores with a mirror finish! On purchasing the vehicle the electronic fuel pump didn't even cross my mind until I got it home, I searched and searched the net until coming across this forum where there was this debate on weather the 200 pump worked in the 300 the answer was no, as I cannot comment on the page thought I would let all wondering know. All you have to do is use 300 cogs time it all up correctly with crank etc then fire away works a treat!
