TD04 Clearnace - Harky - 12-01-2012
Hi guys,
So finally got round to fitting my td04 off a scooby. Had already made up all my adapters etc by just looking at a t2 on a manifold, but today got round to dropping it into my engine...and problems! I've welded the exhaust downpipe at the wrong angle causing it to hit the gear linkage, not overly though worried as I'll just cut and reweld at the weekend.
The other issue is clearance on the steering column. I HAVE clearance..but only just, maybe 10mm, which I fear isn't enough when the engine will be going. So how much do I actually need, and what would my best way be round this. I'm thinking I can grind a bit off the turbo housing where the actuator used to bolt in, this might give me 20-25mm. That enough? Only thing I can think of then is to shim the top engine mount forward a tad?
Last question, my oil in feed is nearly horizontal! I know this should be vertical, but how important is it? To clock the cartridge do I have to take the big circlip off at the compressor side? Already done the hotside so can do it again if needs be, but want to try and keep the compressor outlet in the same position.
Sorry for such a long post and I will get a proper thread going soon!
A few pics of clearance although it looks worse than it is!

Dammmmmmn thats close :o
Re: TD04 Clearnace - mark_airey - 13-01-2012
How the hell have you got it that far over and you should have hit the bulkhead with a big hammer to move it out of the way a bit before you put the engine in
Re: TD04 Clearnace - studturbo - 13-01-2012
Get engine wiped back out and get sledge hammer in haha loads of room then
Re: TD04 Clearnace - Harky - 14-01-2012
@mark: I've the turbo in a near enough stock position as far as I can tell..its just a bit bigger than stock!
@stu: its not quite as bad as it looks...Hammer will probably be employed..its the steering column that im most concerned about just!
Going to trim that wastegate bracket on the turbo, bita a hammer, clock the centre cartridge a bit more ( anyone any tips on this?) and hopefully away I go. What is the minimum clearance i need does anyone know? I know itl be different for every car, but general rule of thumb?
Going a whole weekend without a car is shocking, 3 and a half hr bus and train journey on fri night, and another 4 hours tomorrow..hope this turbo's worth it!
Re: TD04 Clearnace - Ruan - 17-01-2012
Same clearance to the steering rack as mine, and my exhaust side is bigger, and I've done a bit of action with sister sledge and retextured the bulkhead and it fits with no rubbing.
You'll find that the housing actually moves away and down when on/off the throttle... When it's static, that's almost it's worst point. That's what I've found anyway.
Re: TD04 Clearnace - Poodle - 17-01-2012
Oil drain is more important than oil feed to have at >45 degrees, but nearly horizontal is far from ideal. The turbo needs good lubrication, especially if you plan on pushing her. If this isn't water-cooled, then the oil is it's coolant as well, so pretty important to get right if you want the turbo to last long.
Re: TD04 Clearnace - mark_airey - 17-01-2012
*facepalm* I know how big they are, there is one attached to my engine
oil drain needs to be straight down, oil feed requires a custom line making. Oh and its coming off again to clock it round, there is no way your doing it on the car!
Re: TD04 Clearnace - Harky - 17-01-2012
Cheers guys, I'm getting closer to getting it going now.
Have the centre cartridge rotated so oil lines are on the vertical, turbo in, and everything built back up again, just need to do a bit of modification at the exhaust tomorrow, bleed everything and away I go..hopefully! Having grounf off that wee bit on the turbo I'm happy enough with clearance, and haven't had to take out the sledge!
Bit concerned about my wastegate sticking as its not really right but will see what happens and hope for the best!
Re: TD04 Clearnace - mark_airey - 17-01-2012
My wastegate is welded shut so I wouldn't worry as long as it sticks in the closed position
Re: TD04 Clearnace - Harky - 17-01-2012
mark_airey Wrote:My wastegate is welded shut so I wouldn't worry as long as it sticks in the closed position
Yea, thats the plan, if it doesn't play ball it will be forced to stay shut one way or another!
Re: TD04 Clearnace - mark_airey - 17-01-2012
Good good, at least we are on the same lines
Re: TD04 Clearnace - Poodle - 18-01-2012
Ah i thought you meant the oil lines themselves as opposed to the cartridge, yeah cartridge definitely needs to be upright lol.
Re: TD04 Clearnace - Harky - 21-01-2012
So finally got all mounted and built up again on wed. First run didn't exactly go to plan with the o-ring on the high pressure feed busting and loosing the entire contents of my sump over the road! That sorted though and its going again.
Exhaust didn't quite line up so put a flexi in there and de-cat last night and thats it close to sorted.
So few wee issues to sort yet, don't think my wastegate is working right, might be sticking but havn't really played with boost yet, getting about 10psi atm.
The other issue is actually more annoying. When under acceleration there's sort of a raspy noise coming from brake servo area. No thinking its maybe pipes rubbing against the bulkhead, I'm using standard air pipes but they don't quite reach up high enough to bolt on to the intercooler and are just sitting down the back of the engine. I tried to cable tie these tight but it didn't really work and noise is still there! Anyone any suggestions of what this could be, or better still how to stop it!
Re: TD04 Clearnace - mark_airey - 21-01-2012
turbo hitting the cross member of the bulkhead is the source of your noise, just call it on boost engine stabilisation
But yes, its annoying! should have hit it with a hammer more, I have the same issue, need to sort it before it eats my compressor housing but its a turbo off job at least!

Ahh balls if it is..didn't hit it with the hammer at all :oops:
It didn't make it at first, drove 30 odd miles before it started it though.
I must get in under it and rev it, take a look.
Also decided that my actuator is useless and is going to have to be wedged shut for now!
Re: TD04 Clearnace - mark_airey - 21-01-2012
If its anything like mine it won't do it unless its under load it will be touching on the compressor side or on the wastegate as IIRC you have used the gt15 manifold haven't you so you could get the actuator in?
might not be that but thats what I would put my money on mate, have a look, if you watch the gap and rev it if it gets really close then chances are that it will touch while on boost
Re: TD04 Clearnace - Harky - 22-01-2012
Driving it last night I really want to say its not the compressor hitting, or not hitting hard anyway. Its like a fluttering sound nearly, coming from brake servo area. So thinking it might be air pipes maybe hitting off brake pipes or something.Whatever it is it isn't a hard knock, just really really annoying! Could be tuesday before I get a proper look at it, but atm I'm planning on taking air pipes off completely, see what happens then.
As with my manifold, yeap, went with the gt15 manifold, mainly because thats what Anto used in his thread, and as he says, leaves the turbo sitting in a very much stock position. Actuatuor is completely useless, screwed the boost compensator right in last night, only 10psi. As I thought might be the case, my flimsy brackets are probably just flexing, alowing the wastegate to open whenever it so feels...a well, another job to keep me busy at night!
If I get a chance I'll try and get the car washed and a bit of a project thread going soon!
Re: TD04 Clearnace - mark_airey - 22-01-2012
It only just touches and you get a vibrating noise behind your feet when you come off throttle and when fully on boost with mine, not sure how yours will sit as I'm on the other manifold, exhaust is a perfect fit though so its in the right place. Bet that's what it is though
Would be nice to have an actuator and actually know what boost I'm running
Re: TD04 Clearnace - Harky - 22-01-2012
Not the exhaust either :-D .... It hits off the gearstick!
Exhaust would have been in a standard enough place, but I made up a custom adapter instead of trying to weld a cast elbow to a mild steel plate, and might have got the angles a wee bit out, hence had to make up a flexi section.
mark_airey Wrote:Would be nice to have an actuator and actually know what boost I'm running
Have you not even a boost gauge!
I'm yet to be convinced on the td04, hoping it'l be better once I get a bit more boost but currently it doesn't seem half as sharp as my k14 was at 25-30psi, it wasn't going to last much longer though
Re: TD04 Clearnace - darrenjlobb - 22-01-2012
Lol once you get it working correctly, the td04 will blow the k14 out of the water.....

Well lets hope so! Cheers for all the help so far guys!
Re: TD04 Clearnace - studturbo - 22-01-2012
what do you need too fit a TD04 as i will have one come saturday pal
thanks stewart
Re: TD04 Clearnace - Harky - 22-01-2012
If you look on .net Anto did a fairly good write up on how he did his, I did similar.
I took a gt15 manifold, made an adapter plate to bolt to it, which the turbo then bolted to. Exhaust side, I've seen people using the standard elbow mounted on a adapter plate to fit the td04. I went completely custom and welded up my own elbow, this probably isn't ideal. Oil lines, I used standard oil line, with just an adapter to fit it into the td04. Threads on it are something like m10, whereas k14 etc is m12. Oil return is handy enough.
Overall, I took a bit of time making up the brackets etc, then fitting it went badly 'cos I my exhaust adapter wasn't 100% and had no welder, had a few clearance issues, and still have an, as yet undiagnosed, annoying rattle!
Re: TD04 Clearnace - sweeney1987 - 26-01-2012
Getting tempted to fit one meself.
would it be possibe at all to make it fit without bashing the bulkhead?
Re: TD04 Clearnace - Dan! - 26-01-2012
Should be possible Sweeney, just got to mount it at the right angle
Re: TD04 Clearnace - sweeney1987 - 26-01-2012
hmmm, seen a td04 for £40 not a million miles away either. . . . .
Re: TD04 Clearnace - mark_airey - 26-01-2012
apparently with the gt15 manifold it sits lower than with the T2/K14 which should give you enough clearance............
@sweeney, get it bought, mine was £35 :geek:
Re: TD04 Clearnace - sweeney1987 - 26-01-2012
have a k03 sitting there, think its same fanny mould as the GT15?
hmm, dont have time to be f*cking about with the car at the minute though
