The internals of my engine..........first time I've ever seen inside it as well;

Note the liners inside the bores and rather small pistons.
The only consolation of this disaster is that it makes getting at the starter motor and block oil breather so much easier.
So I've taken the chance to replace the starter motor with a Z18XE one (same weight, but geared to make starting easier), and I'm revising the crankcase breather to the later GSi style one.
I've also taken the opportunity to replace some of the old water hoses buried under the inlet plenum with some silicone ones.
Whilst the head is off I will also be doing some measurements on the pistons to see if there's any chance of getting a 16v head on there one day.
Thanks to Mowgli for his research on small GM 16v engines around the World!
are the carbon front wings and bumper your getting going to be one full piece and will you be cutting out the holes on the carbon bonnet ?
dont suppose you know if any ones found or taken video of it yet ?
The carbon front wings and bumper are dsigned to be fitted as one piece and removed all as one. I'm going to be getting them next week so I will post up some photos.Quote:

My friend got a video of me on the startline on his mobile phone, so I'll get him to load it up and post a link on here soon.
colin, as the cutouts prove, the 1600 head is 'too big', so getting 4 little cutouts would be doable...
Just got off the phone to Andrew Bradley (BTEC Racing) who built my Nova and the engine in it.
He's wondering whether the problem could be down to the hydraulic lifters pumping up as a result of the new revs (8k).
I'm out of my experience here, so who knows FACTS about the rev capability of standard lifters, and whether this could explain my sudden loss of power (and the fact that it subsequently ran ok again at idle and revving it up in the paddock).......
There doesn't seem to any leakage on any of the boost hoses, which was one of my possibilities.
I still have to check the fuel pressure in case there is any problem there.
PS - my bore size measures 70.5mm
i believe thats my old bonnet, was waiting for an update to see what it looks like

I'd imagine the lifters are struggling at that rpm, possibly best to get some solids in their Colin.
Will catch up on the thread when I get home as looks like you have had one or two problems !
maybe in the short term, they could do with a good clean & the oil replaced in them, cos it doesn't drain out with the rest of the engine oil when you change it..
but i'd imagine you are at the limit on hyd. lifters
i have always been led to believe the rule of thumb for limit of hydrulics was 7750 and anything around 8k was a job for solids!
