Thanks for that - may be for the next tune I'll include a knock sensor:thumbsup:

I wouldn't bother. First you need to get a knock sensor board for your memcal. Second I was told they aren't that great anyway.
I was thinking about fitting a knock sensor on my engine, but every engine tuner I spoke to said they usually disable knock sensors on tunes, particularly if the engine has roller rockers etc. They tend to retard the timing unnecessarily. If you get your tuner to set your engine up on a particular fuel (eg 98) then the engine won't ping anyway. Mine certainly doesn't.

Nope, only the Group A scored the D port heads.

I know this is old but because people are still reading it I will add that the VP GTS also had D port heads. Plus the VP GTS was the only "black" motor in the VP range (apart from the limited 5000i clubsport). The VP Senator 5000i (200kw) was a red motor


and to clear up other things about cam shafts, the SV5000 had a different profile cam to the VP 200kw engines. There were customer complaints back in the day that the SV5000 was too raw for people driving these cars. So when the 200kw VP range was released they were somewhat subdued

I know it's a thread dig but somebody else did the digging - I just did the reading

Having owned two of the 4 bolt motors I can categorically confirm they do come with the D port heads.
