Everything above new bar the cam's.
Gutted about your engine Craig, the new unit looks massive compared to your old unit.
Everyone has different theories on engine run ins. Personally I would have put as close to 1000 miles on it as possible before climbing rpm much above 4,5k; then an oil change. You could just pootle about on the rebuild now you've got a map?
Thanks Leigh, yes the new place is a nice size. Its predominantly business space of course, but does have its perks.Quote:

Another fecking tensioner bolt failure!? I can't stress enough how crap they are! Hence why mine have been beefed up! It was suggested by Ridgeway too... Is that on the cards now craig?
I had a meeting with Paul at Ridgeway a few months back to talk about it when they crack tested the head. They aren't happy about re-using any of the parts and don't want to put their name to it without fitting a steel crank (which conveniently they can supply). If it went to them it would be a hugely expensive build so although I did consider it its not on the cards anytime soon no.
RE the tensioner, it wasn't so much the bolt that failed, but it did loosen enough to allow my idler to slip round. It was a trimmed down adjustable pulley from the gates kit which in hindsight wasn't a great idea as when it loosened it quite obviously allowed the belt to slacken off. When we put it back together i used another fixed roller and tensioned the belt on the water pump.
SBD did develop a brace for that area last year, but from what I can see it's nothing I couldn't make myself, so one of those will be going on too.

Those do look to be a good move from SBD; I'm also making an anti belt flap roller bearing solution for in between the two verniers.
...I didn't like the look of the belt movement at high rpm, watching mine on the rollers a couple of months back.
Ooh yes that sbd brace looks sensible and should reduce the stress on the bolts...
im sure ridgeway wouldn't be cheap either, especially with the addition of one of their cranks!
Gutted for you over the probs you've had. Glad you're gonna be carrying on and upwards tho.
After having lunched my X16XE that had only done 2k miles after an expensive rebuild, I know exactly how you feel. Crap. It's salvagable but it costs money that could be spent on other things. Hope you get to the bottom of this and that you can avoid similar misery in the future. Keep us posted.Quote:

Sadly the crank is scrap, so may have to use a late one in it, but hey, what difference will it make.

Now also have a full set of rods to use in it, after it wrecked #4 last time around.

I'l just chip away at it and hope to use it sometime this year. Sadly it may not see the Quaife box again, as that's now on the Astra and i quite like it.
Hey Graig nice to see you are back on this one, looking forward to watching progress once again. Hope all goes well this time around.:thumb:
With it all out are you not tempted to knife edge the crank?
This was the first project thread I read when I joined PNG, hopefully see it working again soon!!
Glad to see you've got some enthusiasm back for the nova
It's 100% going back together, with the new engine being nearly finished. I Decided I didn't have the time, tools or confidence to do it myself so sent it somewhere reputable. Same engine spec as before, but as above will be minus the Quaife gearbox and gripper diff, just with a modified Daewoo box and a used Tran-x.
It's also never going to be a track car now, but will always look like one.
Thanks for reading, I forget about this thread.
Arrow rods mmmm :thumb:
Good news.
whats the ETA on the finished engine?
So it will be a road car but in track look? Why did you have to bin the crank? Glad your carrying on with it.
Pics pics pics.
No idea, hopefully built and dyno'd soon, then fitted when I get the time.Quote:

It should look like a reasonably tidy road going car if you chuck some glass windows back in it. Just a bit mental under the bonnet lol
Having it dyno'd and run in out of the car!! I wanted to do that with my new engine but means having mine off the road so I can use the throttle bodies and exhaust.
Sadly track cars are built to take abuse.
Quite like yourself Benn I wouldn't feel too comfortable aimlessly hooning it around a track just to impress a crowd. I have an ITB'd Astra GTE to do that in with a fraction of the money in it. Ironically that would probably wipe the floor with the Nova too.Quote:

That's what has really stopped me doing it again as much as i would love too. Looking back at old videos, my lap times where better and i drove much faster.. As i didn't worry about the car as much then as i do now.
So totally understandable when you've sunk money in to it like you have.
Astra is a full on set up track car, so perfect for it and would be perfect for circuit racing too.
Wimps get out there and rag them lol

Awesome!!
Top shelf video!!!!
What are you looking down at at the end of each lap??
That Astra is FCing quick; chassis looks to be done right too. Open diff or LSD with the spur gears?
I'd imaginie its the lap timer
That astra is hugely impressive Craig !
Thanks James, Its long gone now as you know.
The Nova is almost back together though.

Quite a few little changes and a change of plan again, so keep an eye out for it in Red & White this year.

Do you have a picture of the planned colour scheme? All the fastest cars are red so good choice.
Everyone knows red cars are fastest!!!Quote:

Excellent stuff.Best of luck with the racing mate.
Engine bay looks great nice work, what wiper motor are you using if you don't mind me asking please?
Wiper is a Fiat Uno one. They are pretty hard to find used.
Proposed colour scheme. Numbers are on and a few bits are painted, But the motor had to come out again last week which is a bit of a set back.
