Joff's Nova Turbo Project

just been reading this for 2 1/2 hours (45 pages) wot a motor an absoulte one off good work mate keep us updated

Chaps,

Sorry for the delay in updates but its been a bit hectic at work and I needed to take some time out to help the wife decorate :( !!!

Anyway normal service is now being resumed....

As you know the engine & gearbox is in and I am now in the process of sorting out the gear linkage and
problem with the alternator pulley catching the inner wing.

The gear linkage is a bit of a pain as I have had to use a couple of rose joints and getting everything lined up
for all 6 forward gears is getting to be a pain. There is also to much play in the ball joint cups on the old nova
linkage so I am investing in some newer gearlinkage parts from a corsa off ebay and hopefully this will solve
some of the problems. I spent 3 hours Sunday playing with the linkage and it still doesn't work .... grrrrrrr !

The alternator pulley situation has had a more positive out come. I was trying to use the pulleys as seen here :-

These use the mutli-v belt which is considerably less likely to jump off the pulleys at high RPM. One problem
- the multi-v pulley was less than 1mm from the chassis leg - not really a viable option.

I then contacted a mate who gets his dad to knock up alloy pulleys to make up a set (top and bottom) with a deeper
single V which will hiold the belt a lot better.

Here's the bottom pulley :-

And here's the clearance between the alternator pulley and the chassis leg , close but about right for a nova 16v conversion!

Once the gear linkage situation is sorted I can then start on the pipework around the engine and then carry out
the final head torquing sequence.

Cheers for now

Yep, chap called Graham , lives a couple of villages away from me. Currently rebuilding his C20LET into his Mk1 Astra . He put a couple of rods through the side of his block a while back and is rebuilding his engine to a similar spec to mine!

He was just doing bottom pulleys but I asked him if he could look at top ones and hey presto a week later we're sorted!

Joff

wish i had the clearance on my alt :(

What did you do to your linkage before joff? As you ran a 6 speed before.

I hate sorting the linkage on Nova's wether it be a Turbo or a 1.0l there just a pain.

Great work as ever, any ETA on the finished product Joff?

I have sourced a new quick shift linkage from Rally Design.

Problem is that the top link bar no longer reaches so have had to put in some rose joints and threaded bar. The plastic sockets that hold the ball joints on the end of the linkage are all cracked and keep popping out - all in all a bit of a pain.

I am sourcing a corsa linkage to have a play with which should help.

ETA on finishing - probably Feb/March2007 .

Got all the wiring sorted for the dash - its also got a carpet in as well now!!! (I Know I get excited about rather minor things but it hasn;t had a carpet in since Feb 2003 !!!!)

Dash should be going in sometime shortly once i have sorted the pipework for the side vents.

Joff

Sounds good. Coming together inside.... creature comforts & all (carpet).

Someone needs to source these plastic, ball retainers for the linkages. GM no longer stock them & all the ones Ive found have gone brittle.
