Reply With QuoteHas the wastegate modulator ever been replaced?

When I bought my D2a, seven or eight years ago, it was a slug. It hasn't improved since, despite minor fiddling with the wastegate adjustment, new silicone hoses, new MAF and MAP and the regular fuel and air filter replacements.
Full noise it struggles to push .7 bar of boost, according to the Nanocom.
I have a brand new 20241025_202725.jpg, apart from the bracketry and fancy anodized finish, is there any difference between them. In other words, are they model specific?
Some time ago Discorevy (?) recommended an upgraded turbo core, was it this one?

Can they be fitted in the home shed, or do they need specialist fitting and balancing?

wastegate modulator, being the anodized diaphragm thingy pictured? Not to my knowledge. Or any other major bits.

The upgraded turbo core won't really make much (if any) extra boost than the stock one.
If you have a nanocom, post a log of it under performing, and someone (possibly even me), will take a look.

I'll ask Chook if he can help me.

SupporterThe item Graeme was referring to is the electronic gizmo bolted (from memory) onto the A/C compressor. Has 3 little hoses going to it, one runs to the thing you put a picture up of.

That actually leads into my next question, if I replace the turbo, where do I get a sensible remap? Definitely not looking to be the first away from the lights, but would appreciate a bit more low and midrange torque.

I'll look over the weekend, but doubt it's ever been changed. Heck, the car only clicked over 250,000 km this week. Is nothing made to last, any more?

SubscriberAsk him if he can check that the actual wastegate isn't stuck partially open when he's there.
James is the one for your "sensible" remap, after the problem has been addressed.
Happily, apart from minor niggles, the rest of the Car is made to last. If it has been properly serviced, you can expect at least 700 000 odd kilometres from that engine before a rebuild is on the cards.

The one in my new '99 failed within a couple of months, just slightly less than your 250K. However its failure was to not limit boost at all which caused fuel cut-out under any sort of load.Heck, the car only clicked over 250,000 km this week. Is nothing made to last, any more?
