Yep, my wastegate was lubed up and problem solved. Hope it's as simple as this for you.

eta, I seem to remember we used ceramic grease as it's right by the glowing red manifold

I imagine this would also make sense given my original point about driving through rather deep water....!

I've had a poke around, it looks like the wastegate is fine, spark plugs looked alright, although admittedly I did only check two, as I was already telling myself it's a better idea to send it off.

So it's getting collected tomorrow - annoying to be ploughing more money into it, but part of me does feel better knowing the people that know it best are going to give it some TLC and so it should come back free of all the little niggles.

I think I had this problem in around 2002 :-)

Boost solenoid????

Cold wet weather also helps create a bit more boost

Will report back once it's been looked at, my options to fix myself are pretty limited so it's probably best it's going to a pro.

Bit late now as the car has been sent away but I did have the same issue with mine after it had been away for a while to have some work down. I suspected the plugs had fouled themselves as the car had been moved about and started/ stopped with a cold engine. I bought new plugs and gapped them down as small as possible( as I am running higher boost) and also installed some updated coil packs from Rossport. Before I did this under full boost between 4000-5000 rpm I would get a violent cut out and backfire. The plugs and coil replacement cured this.

Interesting, will report back when they've looked at it, scheduled this week I think.
They're doing cam belt and a few other bits too, so even if the power cut is a simple fix it's still worth sending it to them.

Hi

I had to move to the “Spoolin up” coil packs because mine was rough at high RPM and also ATE plugs for breakfast and they fixed it

Apparently they are the packs from a regular Yaris

The car is still with them.

During their inspections etc they have found awful levels of rust, so they didn't even bother finding out what that initial problem was.

Long story short, it's either a HUGE expense on a full restoration, or it's basically not much better than scrap.

I'm devastated quite frankly, never thought I'd sell this car having owned it for 13 years, and now suddenly the last time I drove it onto the back of that truck might be the last time I even saw it. So gutted, not to mention the huge financial hit I'm going to take having ploughed so much money into it over the years.

So sorry to hear that. Give yourself some time to think about what you want to do, on the one hand Evos aren't losing money right now especially clean ones. On the other if it's that bad, it's just a car at the end of the day. Can always be replaced.

If the shell is that bad you could also look at transplanting the running gear into a clean shell without an engine.

Yeah I'm not going to rush a decision. My heart is telling me to park it up in my garage for however long it takes for me to have the money in the bank and happy to spend it on getting it restored. But it's not a small number by any means, and wouldn't be the wisest decision from a business POV.

But it's a car I never thought I'd be without, so letting it go for next to nothing is doubly painful.

The problem is that half the reason it's so special is that is has the chassis No it has etc associated with being an RS450......

If it were mine I'd get a specialist welder to look at it and give a quote.

Well it's currently with an evo specialist who have recently done a full restoration on a Skyline, so they know pretty much exactly what mine would require, so I do have a number. And it's not pretty.

Not sure if sending it elsewhere would achieve anything, I fear a lower quote might start off promising but then costs spiral as the work progresses. At least my guys know what sort of numbers we're talking from the start.

I’m gutted for you!

C1 R are located next to the man who originally supplied your car and he also worked for him back in the Ralliart / Xtreme days, it may be worth having a chat with him (Chris) as I know they’ve done small and major restorations!

The EVO 6 is ALWAYS going to be something legendary!

It cannot go in the bin, just consider it a long term thing!

It’s amazing how EVOs can look very good FROM THE OUTSIDE but are pretty bad underneath (I know this personally unfortunately)

As you can imagine my mind is just going over and over the scenarios. I REALLY don't want to lose it, but can one justify spending say £40k on a car that's already had that much spent over 10 years? I just don't know. Who knows how earnings etc will go over the next, say, 5 years, so maybe I should just garage it until spending that amount isn't eye watering. Really not sure what the right thing to do is.
Still waiting to hear what, if anything, the guys who have it now would offer for it in the current state. They know better than most how special this particular model is, so maybe they'll seem some value in taking it on.

You really should speak to Chris at C1 R, he probably did the PDI check on your car when it was sold new!

£40k to re shell or repair??

My 6 was deteriorating, Chris cleaned the underneath up massively and as crazy as it sounds an “as new” 7RS came up at a good price so I bought it as an alternative to fully restoring my 6 but….. the value of the 7 RS has increased to make it unuseable and it’s not my 6 (that I’ve owned from new)

Forget the money you’ve already spent on it, it’s done!

These cars will never be replaced, the GR Yaris is not an EVO!

That's to fully restore the current shell, including what it would probably cost to respray everything as well as all the paintwork is in a pretty dismal condition too.
It's not an exact quote as it's a bit of a 'who knows' job, but they're basing it somewhere around their experience with the Skyline they restored in terms of man hours that took.

I'll def give C1 R a call, think I remember coming across them on the MLR forums back in the day. I'll happily speak to anyone who might give me some hope that it could be saved for anywhere approaching a reasonable amount.

You may not have to go that far without not doing enough!

There can be NO END to restoration so you have to compromise!
