Coulda bloody told me.
I have one sat in the shed, waiting for you!
Only joking :)
You got everything else you need?
Is it a Turbo 'box?

Hi
Got another question. If I raise the boost pressure to 10-14 psi on the 480, what plugs do I need? Are the standard plugs good enough, operating under increased pressure?
What do you experts suggest.
:lol: I thought I asked you & it was taken already.....yes mate a turbo box. Just found a flywheel today, from an F4R Clio. 60-2 pattern.

If you are upping the boost I would go 1 or 2 grades colder. An expert once recommended me an NGK BPR9ES. Or BPR8EIX iridiums ones if you are rich. If the plug fouls quickly then the grade is 'too cold'.
The ignition system has a safety cut out at around 1 bar or just above, so careful you don't bounce off that too much. It will feel like the engine has cut out. Raising just the boost won't get you much though, better to change timing/injection by getting hold of a modified ECU
//edit oh and I close up the gaps of the plugs a little when upping the boost.
Thanks Jamesy, good info
By the way, just so you know:
It's pretty much traditional around here to derail threads wherever possible.
Usually myself and Jamesy whenever 400 series are involved :lol:
This cat agrees with you

Upping the boost with an MBC. Looking at my Wastegate actuator, it has a red tube running to the pressure switch. Is this the line into which to put the MBC.
I am still wanting the proper ECU mod. This is just temporary.......for fun
I need some help in re-coding my original Volvo 480 radio. I have the code but can't for the life of me work out how to enter the numbers. I have used the preset numbers 1-4 but the code has numbers above 4. Also, when you have entered the code, how do you finalise the operation or does it do it automatically?
I can't recommend upping the boost without sorting out the fuelling to match - mine was overboosting & killed the engine. No idea about MBC's, sorry
^^^^^^^^ What he said. ^^^^^^^^
The fuel/ignition system on these isn't the smartest, although safe if modified properly.
An MBC would spell bad news, as it won't be able to adjust to suit before going pop very quickly.
Got Robou's mod in now. The turbo gauge doesn't show any more boost than original, although the power is obviously up???? I have the new dump valve to fit, which might make a difference. On hard acceleration at high revs, I can hear a short sharp hiss, not like a waste gate opening, so might be leakage around the pipes to the actuator (robou's suggestion). It certainly is not delivering full poke but is much better than standard. Pulls from 1000 rpm and his test of 45kph, smooth as silk.
Has anyone got a turbo gauge set to sell, otherwise I will use an Ebay pressure gauge to individually check the turbo gauge reading.
Ebay gauge will do you mate, performance will be better even without extra boost due to fuel & timing changes by Mr Robou
Remember to adjust the resistance setting on the MAF...should be about 530 ohms between pins 2 & 6...with 6 being closest to the adjustment screw..

Ta.... where does this thingy hide itself?. I was looking at the square unit in the air intake back from the box. The one you are showing seems to be round or is that an illusion!!! Gaud I need to learn fast..........
It's attatched to the inlet hose, immediately after the airbox, about 4" long with a plug attatched to it.
what steve said^^

Sorted the MAF resistance to 530 ohms. Had new turbo fitted and they set the actuator to open early for bedding in ( I don't know why) and did full pressure leak checks. I need to know, on my model 92, which way to close the actuator to delay it as I am getting less than standard pressure, or do I have to open it???????. I have the Robou fitted, new Audi dump valve and less than impressed with lack of pressure. Hardly going to 12 o'clock. Thanks

maybe best to ask the garage who moved it to put it back where it should be
Yup, I twigged the b...££££ about the turbo but the company who reconditioned my turbo set the wastegate to open early. I have every confidence that when I have corrected the mistake to "half a hole" or around 5mm not the 1-2 mm movement of the actuator rod they imposed on me, some more power will appear. I unlocked the actuator rod, loosening the 10mm nut, removed the circlip and pulled off the rod from wastegate spigot. I tried to rotate the turnbuckle but could not actually move it. Locking compound or crimping??? Looks like a small dimple in the turnbuckle body.
What I am very interested in is the condition of the regulating valve. If this indeed triggered a fault in my Robou, then it will have to go back and be mended.
Would anyone have a known, proven, regulating valve I can buy from them please. It would be pointless to have the ECU checked to find the regulating valve may blow it again. I will, of course check the resistance as Robou suggested.
The red pipe from the regulating valve goes to a new diaphragm working the actuator rod. The wastegate is new.
The white pipe goes from the turbo area to the regulating valve. Let me know if the set up is erroneous.
This is all proving quite disheartening.
