New FD Owner Gloucestershire
« on: October 19, 2017, 07:34:53 PM »
Hi,

After many years of wanting, umming and arring whether to sell up and get the money together for an FD, last month I bit the bullet!

Managed to get a fairly standard, low mileage import that was bought into the country by new era imports 2 years back.

Plan is to keep it pretty much as it is, keep it maintained, tidy and enjoy it!

Anyway, pics as I know that's what people want to see!

Will be good to get to know some like minded people and learn from the wealth of knowledge on the forum!

Cheers, Doz.

Cheers!

A couple of niggles to sort out (secondary turbo boost problems) give it a full service, underseal and cavity wax for now. Nothing too major & I've already got a vacuum tester and a load of new vac hose so I'll get stuck in in due course!

Good to see another one pop up on here as FD's getting quite rarer by the minute in UK.

From personal experience of twins...check the basics first...i.e all boost pipes from turbos for loose clamps( large jubilees etc). Whilst will hold on primary turbo as it trys to transistion you get a whoosing noise and loose all boost pressure...i thought it was a vacuum pipe or solenoid...but just a loose jubilee that seemed tight.
If you havent got a boost gauge defo hook 1 up to see whats going on.

Thanks,

Yeah I'm going through it with a fine toothed comb. It came with a defi boost and water temp gauge fitted so atleast I can see what's going on.

To date it will boost primary but then boost rapidly tails off in secondary (May not be kicking in). Change up a gear and I'll get ~4psi and get a turbo chatter noise when I lift off. Change up again and get full boost back for it to fade higher in the rpm range.

Fitted a new valve block (1996+ rats nest) as a 50/50 it'll fix it or atleast be a good preventative measure. No joy here, if anything I even more rarely get full boost and get stuck with the same ~4psi scenario across the board.

So to date I've:

>Tested the two boost control solenoids with power etc -ok.
>Replaced the block of other solenoids.
>Replaced all one way check valves.
>Tested all three turbo actuators - ok.
>Tested and replaced the blow off valve - this was found to be always open.
>Tested the charge control  valve - ok.
>Tested the butterfly valve that links up the second turbo - ok.
>Replaced any vacuum hoses I can find with silicone.
>Checked pressure chamber - ok.
>Checked vacuum chamber - ok.
>Checked all intercooler pipework/clamps.

So far no smoking gun, but I'll keep plugging. Worrying thing is that I'm running out of ideas!

Any opinions welcome! The cars a 1996 with around 80k kms / 50k miles if that's worth noting.

Thanks!

Looking at that lot...youve pretty much been through what i went through with mine and found no smoking gun...
Intercooler core leak only thing i can add...poss on the joins.
What happens on part throttle up through rev range?

That's a good shout I can pressure test the intercooler system.

I don't recall actually trying half throttle. I have tested the valve for the throttle actuation though and that works as it should. Only solenoid left is the turbo control vacuum solenoid.

Atleast if I change every hose so I know that's good. Some of the originals where soo brittle including the 90 degree hose that goes to the charge relief valve.

The car certainly feels strong and eager when it boosts fully on primary. Will be glad to unlock the full potential!

Ok mate since you have tested most things topside and as this is a secondary turbo issue you need to jack it up.  Once infer the turbo pack you will see the three actuator arms. Check the C clips are fitted and all actuator arms are connected. If these are all fine check the hoses to the actuators.

I didn't see on the topside testing but worth checking the charge control actuator as its very easy.  Key on, key off and you will see the actuator arm move about about an inch in/ out.  Its just in front of the brake servo.

Couple of questions.
1. Did you buy with this issue?
2. Std Ecu or Apexi?
3.  What downpipe fitted to the car?.
4. What max psi boost are you seeing?
5. When it drops off boost what rpm?
Part throttle can help rule out solenoids if leak or fuel cut. As will transistion.

Mine was spiking to 16psi...it would fuel cut at 17psi on cold damp day...mines on an apexi and wastegates are over whelmed so just keeps building boost with duty on the soleniods at max. Solved with an 2.5" orifice pipe in flange between dp and midpipe....now 13 5psi all day long .
Have you got the defi controller to record the boost pattern ?

Yeah unfortunately bought with the issue. Didn't give it enough beans to notice until a couple of days after. Only myself to blame for that!

Stock downpipe and ecu. Only mods engine wise are a maxdaspeed cat back, hks panel filter and hks intercooler hard pipes.

Boost spikes at max ~13psi unfortunately I don't think the defi has a controller (unless I've not found it yet). It drops off post 4.5k rpm but since I've fitted the new valve block it seems to more frequently only give me ~4psi before that too?!

I've checked the circlips on the underside and they're all good. The charge actuator goes in/out with key on key off also.

Appreciate the help guys, I like to think I'm pretty adept technically with cars, first time owning an FD though!

Worth noting I'm going through the hoses to the actuators as a next step while I'm there. Haven't found anything half as bad as the top side vac hoses so far though!
