Phoenix from the flames - Porsche Boxster with an Audi 2.7T
Discussion
Thanks everyone. 
1. When I went to put the fire out initially, the exhaust wrap was on fire, it's not flammable so that means it was either soaked in fuel or oil.
2. The ECU log showed the oil pressure dropped, the fuel pressure was the same. The initial smoke from the back of the car when I was driving was blue, I thought the turbo had blown at first. This points to an oil leak.
3. The point where it looked like the fire had started was at the top of the engine at the back, above the gearbox. That's where my oil feed was for the turbo was.
4. The banjo bolt holding the oil pipe to the engine is still tight.

Think I actually prefer the new colour choice!
I wouldn't have chosen red but now i've got it, I quite like it, think I prefer it to the ocean blue the old car was. You don't see that many in red. superkarl said:
A great deal more can be had from the 2.7tt in standard format by using KO4 turbos and beyond that hybrid turbos utilising wheels and housings from the rest of the VAG range. 400-1000hp is achievable in the standard format.
I guess the benefit of your first build was packaging.
Fitting two turbos which are outside the V certainly doesn't make things easier.
I dare you to try and convert the engine to run with turbos inside the V
In the Boxster engine compartment with the Audi V6 there is loads of space at the sides of the engine but no space above it. There are pros and cons to both single turbo and twin turbos. Keeping twin turbos means everything is as designed by Audi which should make it reliable and it'll just work as it should straight away. That said it's all so tightly packaged that it's a nightmare to work on, even with the engine out of the car. It's also harder to design and fabricate all the pipe work for twin turbos as the original Audi stuff won't fit. I guess the benefit of your first build was packaging.

what is the second exhaust for?
It's a screamer pipe for the external wastegate. They are typically fed back into the exhaust after the turbo.HybridAero said:
Awesome to hear and phenomenal response via GoFundMe.
I know it's a sore subject but did you find out what caused the fire?
The gofundme has been fantastic, everyone has been very generous and it's much appreciated. I'm not 100% sure on the cause of the fire, it's hard to say with total certainty as it was carnage afterwards but I think it was the turbo oil feed which failed where it was crimped, leaked onto the exhaust and caught fire. I think this because...I know it's a sore subject but did you find out what caused the fire?

After that experience, I don't think a plumbed in fire extinguisher is overkill on any modified car. Especially a Boxster or Cayman where the engine bay is difficult to access. It's something I'll be fitting to this car.
With my build it's something that's gone from a "well I'll have two in the cabin and it might be an idea to have a plumbed in one" to "I'm fitting one" (as well as two in the cabin). I'm sure you will, but can you also note on here how you fit yours in, what works etc! - just so us inept can look at it it and try fit one ourselves!
I don't think I will be plumbing one into my car, but would like to consider one plumbed into the garage at home.
Also to say I'm in, watching the phoenix here!

I may be able to help you with that if the timing is right, I have one in a car which I don't think I'll be needing and it's never been used. 2.25 litre though, the minimum size the MSA required when building the car, you might want to go bigger?Robmarriott said:

Sounds good, i'd be interested.ikarl said:
Genuinely excited for this!
Quick question.... how easy/difficult would the project be to just swap in the 2.7tt engine without massively modifying/tuning it? i.e. Just the basics to make it a viable daily car?
This is probably the way i'll go this time around. I've had the engine running on the standard management in the old Boxster previously.

Excellent, I'd certainly be interested in finding out how easy it is to turn-key a boxster to a tt ikarl said:
