Turbo came today
So with what little time I had today I den this,
Had to it 3 studs to manifold, and leave one in turbo
Then set about making a flange in preparations fr new exhaust system I need to Make,
Bit of 10mm laying about, I have no precision tools, so everything is done with grinder lol
I've had to rotate turbo, so last thing to o is make actuator bracket, and a we oil feed pipe!

Loving it
Well, it looks a bit bigger lol !
But I done my usual test with blow fun into the exhaust housing, and this thing spools up really fast, so much better than last turbo, and makes quite a bit of air even with just a blow gun powering it! Where as last one made hardly anything so I'm quite confident il get some boost this time

Excellent
Me too!!
Does seem a bit one step foward, two steps back right now, but it's getting in the right direction
Definitely think you're improving it with each incarnation. Fannymould and turbo both seem better and now you have wideband...Me too!!

Made this today.
Only problem now is the alternator, again!
It's sitting on the wastegate actuator
So I'm either gunna have to move alternator, or fit an external wastegate, only place to move alternator would be underneath turbo, but then I'd have to cut cam belt cover!
Sucks not having the car at workshop, I have to run back and forth to measure things, then I make stuff, then realise something ain't right, aaaassarrrrrgggghh !!

Got a bigger hammer?
Look at the stuff you've fabbed so far dude, moving the alternator shouldn't be too difficult for you

There's not a hammer bug enough in the world for what I want to do with that alternator.
Stupid cars needing stupid alternators in stupid places!

I suppose, it's jus a chore!
External wastegate would be easier!
I can understand that it's another hold up and you're desperate to get the bugger up n running but you'll get there dude. If it's easier then why not do external w/g
Oh dear, feel your pain dude. Can't even remember last time I had a bit of disposable......

Hmmmm yet again you hold the answer!
Il have a look tomorrow and see what's possible
Jus so it's in my head, how would you weld internal gate shut?
Is an external better ?

as long as its in the airflow, so that the bracket wont get too hot mate,
and fitting a strong spring to hold the w/g shut is preferable to welding the puck down really, thats how my TD05 is setup, because like yours it wont be creating any more than 10 psi anyway
external is just a bit better in regards of gasflow basically

Been busy again today
So this is what I've done for oil return for turbo
Drill hole
Cut 3/8 bsp thread into nut
Weld it on so I can use hose tail fittings
The fitting on the right is what was on the turbo, left fitting is oil feed flange for old t2 turbo
So drilled it out and tapped it
Now I jus need to cut length of high temp oil hose abd i can attach it all up

I put it back to where it was, closed of wastegate with big spring for now, have fit external wastegate when I've got some more money lol
Mrs just booked holiday so cash is tight now, but luckily I bought everything I need to keep me busy with it fir next few weeks, wish I had a garage, or a man shed. Working on driveway is freezing and filthy!

So, got my first boost experience today, like most first times, it didn't last to long (giggedy)
It was fun tho! Turbo came on a lot sooner too than I thought being its quite large, and BOV sound is very addictive.
After I pushed it back to workshop, I found out what stopped it running, for Some reason the charge pipes and intercooler had filled up with fuel !!
Only found this out because I disconnected the boost pipe from carbs, revved it and a few litres of petrol poured out
Emptied it, bolted all back together and slowly got it home,
Ideas anyone ?

My theory is, as the boost went up, so does fuel pressure, to stop the fuel being forced out of the float bowl breathers, they are connected to the pitot tube on plenum, I 'think' this tube is to small so can't deliver the amount of pressure to stop fuel being forced out.
My understanding of this pitot tube is that it's in the direct flow of the boost so should see a tiny % more pressure than what's in the plenum, which should stop fuel being blown out of breathers, and into the venturis of the carbs.
So without that extra pressure, all the fuel has made it into intercooler
