First one was detonation on #6 cylinder causing welding and general bad s
t. It was a warranty rebuild so had to be rebuilt to factory spec. The fact the Warranty Company then wriggled out of paying is a sore point but well in the past now.
This one was a valve seat falling out when the engine was hot but I was parked up. Then when I restarted the engine it munged the cylinder and head.
Ironically, the head and valve seats were pretty much all that was original on the engine after the first rebuild.

Have they built your FFF2 yet ?

Update: Apparently the answer is "yes" now, having just had a phone call from RG. They just wanted to know if I wanted a bottom end rebuild whilst it was out and the head off. I've declined as you have to draw the line somewhere on cost. Dom
Should be back in a couple of weeks - with a FFF2 head and Syvecs.

How would a bottom end build benefit your engine according to RG? Didn't think there had been any bottom end problems with SP6, although it depends who you listen to.... interesting article in Sprint a few months back from RND Engineering... but generally there hasn't been the same chocolate component issues with the bottom end has there ?

Just said that it was exhibiting normal wear and tear with some scoring of the bores and stuff. I was a little surprised as they only rebuilt the engine 3 years / 18½k miles ago with a brand new block, but they assured me it was merely normal wear. I didn't see the benefit of spending yet more money and also having to run the engine in again, so I declined.

Hell yeah!
(Although improved smoothness, tractability, reliability and the addition of Traction Control are all things pretty high on my list too)
Do you fancy a "shoot out"? (Although improved smoothness, tractability, reliability and the addition of Traction Control are all things pretty high on my list too)

I'll join in when I get mine, although it will be a little while yet while they develop the VVT.
I've been told that the VVT is being designed to be fitted in situ rather than requiring the engine out. Got to say that this is a good move considering the labour costs involved in getting the engine in and out. JonRB said:

Decided to get it all done in one hit. I know what the standard set up is and it's delightful, so I'm going to wait for the final package.T40ORA said:

I've been without the Sag for 4 months now, so I wasn't prepared to wait any more. Besides, the FFF2 + Syvecs + simplex timing chain is a hell of a lot of money. The VVT will be down the line for me, I think. natben said:
You guys have some patience!!
The 4.5 from power is up and running, race proven and comes with a warranty and achieves roughly the same BHP as you are hopefully getting with RG and it would have been on your drive months ago. Hope it all come good in the end and is worth the wait.
If I'd wanted to just bore out the engine to make willy-waving bigger power then I could have gone to any number of people. The reason I went to RG is because of the re-engineered head that ditches the Finger-followers and adds extra coolant and oil pathways. I'm not really interested in extra horsepower as such - I'd happily forego that in favour of better reliability and tractability. The 4.5 from power is up and running, race proven and comes with a warranty and achieves roughly the same BHP as you are hopefully getting with RG and it would have been on your drive months ago. Hope it all come good in the end and is worth the wait.
But, please, by all means gloat if that makes you happy.

It's a very different package though and RG is a smaller firm with far fewer staff to carry out the work. Combined with some serious part supply issues due to a fire and issues getting back up and running.

Comparable data from SRR suggests that the outputs are very different as well to just boring the block and/or increasing the stroke as it would seem to focus on getting more air in and through and various other things.
They are both solutions to similar problems but from very different angles and as such will suit different customers.
Drive the two options back to back and they are really very, very different in the way they deliver their power.
It's an immensely engaging engine that hugely enhances the driving experience if you want a very revvy, super smooth unit that is calm low down but flies at higher revs and let's you really feel like you are driving.
Other people like more of a low down punch. More of a v8 sort of character.
I don't personally see right or wrong in either, just personal preference.
