The adaptor flange for the turbo is bolted on, no welding involved.
Awesome stuff mate. That's good news to me if its bolted rather than welded.
Here you go, hope they are useful;Quote:

Now moved to a temporary new home on the patio, pending completion of the garage floor;

Another area for a little bit of weight saving, the windscreen brace is getting replaced with carbon fibre tube;

And a new instrument binnacle, I plan to replace the existing STACK dash display with something simpler and cheaper;

That's awesome mate thanks very much for doing that. it gives me an idea of how it is possible to adapt one. Although your turbo doesn't have a standard 4 bolt fitting?
Looks similar to some subaru fitment turbos ive seen, wouldnt be hard to make up an adaptor with say a t2/t3 4 bolt flange though :)Quote:

The end is in sight, I will be ordering the concrete for the floor next week when I get paid, and then the Nova has its official home. Can't wait.
Today I have been playing about with the brakes. Regular readers will remember that I engineered a one-off rear brake solution, using a KAD kit for a Classic Mini;
http://i285.photobucket.com/albums/l...psb0f1e15f.jpg
This works brilliantly, and looks lovely, but I've felt it was still overweight for my aims of ultimate lightness, and if the rules allowed it I would get rid of the rear brakes completely.
However, there is a requirement to have functional rear brakes, so I have to comply. I've therefore decided to sell the KAD/Nova hybrid set-up, and do something different.
When I weighed the KAD rear calipers, I was surprised how heavy they are;
http://i285.photobucket.com/albums/l...pse741c767.jpg
The plan now is to use the alloy rear hub kit from Berrisford (Autograss specialists), and a very tiny disc and caliper, absolutely as small as I can get away with;
http://www.berrisford.co.uk/product_...ui5h9amue3pkn4
That is suprisingly heavy. I can't find the pictures of the UPG setup but they were quite simply using a solid bar as an axle like the grass track boys use with bike calipers and discs. The front just used machined flanges and bike calipers and discs again.
I'm not sure how good the setup was, it's not like brakes were particularly important for drag racing, apart from the weight saved.
Of course the front brakes cannot escape similar attentions, and this is the current set-up;
http://i285.photobucket.com/albums/l...psbe744915.jpg
http://i285.photobucket.com/albums/l...ps882c752f.jpg
http://i285.photobucket.com/albums/l...pscc650bb5.jpg
Solid, cross-drilled discs from an OMS single seater, with alloy bells, and 'Gold Spot' calipers from a Yamaha R1 motorcycle. Likewise, they work very well indeed, but again I felt there was room for reducing weight, and maybe increasing performance as well.
So I have really pushed the boat out, and bought a full set of ISR calipers, together with lightweight rotors (discs), floating on alloy bells. These are absolute works of art!
http://i285.photobucket.com/albums/l...ps70cf661f.jpg
http://i285.photobucket.com/albums/l...ps7bae0ca3.jpg
http://i285.photobucket.com/albums/l...ps1cde62f0.jpg
http://i285.photobucket.com/albums/l...psac87a87f.jpg
The front rotors are 280mm,and the rears are 235mm. Front calipers are 6-pot, and the rears are 4-pot.
As discussed above, I need almost no rear brakes, so I won't be using the rear ones, which I will sell on to recoup some of my money.
In terms of weight, the 'old' front discs were comparatively pretty heavy;
http://i285.photobucket.com/albums/l...psca6874c0.jpg
The new 280mm disc is a lot lighter;
http://i285.photobucket.com/albums/l...psa52fb613.jpg
And it's the same story for the calipers;
http://i285.photobucket.com/albums/l...ps2ad73679.jpg
http://i285.photobucket.com/albums/l...ps67b27e83.jpg
Basically a saving of nearly 1kg off the unsprung weight on the front end, coupled with what should be a big improvement in braking (280mm diameter in place of 240mm), and 6 piston calipers instead of 4.
And fingers crossed I should be able to get a large part of my money back when I sell all the old bits.
And they should be pretty easy to fit as well, the calipers use the same 108mm centres for mounting, so I just need to make new brackets to space the caliper a bit further out, and obviously adjust to suit the offset of the new bell. And the bell needs to be re-drilled for the Nova wheel stud PCD.
Talking of saving weight, I am currently talking to my best mate's Brother In Law, who is a superb CNC machinist. I'm hoping to persuade him to do the caliper brackets, but more importantly to machine me a set of front hubs (uprights) out of a billet of aluminium.
This would be a major coup, if it comes off!
Simply amazing!i like so much the new front end.
Thank-you. I'm very pleased with the way the new front end has come out.Quote:

I was talking to Boris about buying the car from them, but their asking price is way over what I value it at.
I did ask them for more details on the brakes, and also the gearbox, but they haven't replied.
If the price was realistic I was planning to keep the carbon flip front, tailgate and doors, and sell the rest of it on ASAP.
Sent you a email Colin.
Wow am loving the brake set up. Discs look huge.
New brakes look very nice :) colin how do you get away with running rear coilovers but not having turrets? as i know you not allowed to remove metal in such areas

In an effort to fund my engine rebuild (just got the first part of the bill!), I need to sell a lot of stuff.
There's a batch of bits on EBAY now, search for HILLCLIMBESCORT as my User Name to find them.
Items include;
ISR 4-pot calipers
ISR floating discs and alloy bells
STACK dash display system
STACK 52mm boost pressure, fuel pressure and wide-band lambda gauges
Carbon fibre dashboard
and lots more stuff to follow soon..........
That lot is gonna go thru the roof^ Looking at the way it it wants me to bid...lol
It needs to go through a very high roof to cover the costs of this engine rebuild.
My 2012 crash is proving to be an extremely expensive mistake!
Funny, crashes at full speed arnt normally cheap....
And put it this way, the bit i thought i'd try a price on wanted more than 65 pounds....
Not a huge amount to report on, but I have just got the front disc bells, the rear hubs and the steering rack mounts back from the anodisers.
I had a slight re-think, and I'm now going to use the smaller diameter brakes and the 4-pot calipers, rather than the big 280mm discs and 6-pots.
The freshly coloured bells are now re-attached to the brake rotors, and look quite nice;

http://i285.photobucket.com/albums/l...ps6c6fface.jpg
My latest plan is to utilise mountain bike brakes on the rear end. I will get some stainless steel brake discs laser cut to suit, and use these Hope Mono calipers.
http://i285.photobucket.com/albums/l...pse961abf8.jpg
I reckon if I use a big master cylinder, plus a pressure limiting valve, the back brakes will be doing so little work that they shouldn't overheat and self-destruct.
That's the theory anyway. The back brakes have to be functional if a scrutineer wanted to check, so as long as it can stop a back wheel turning when the car's jacked up, that's good enough.
Will the hope ones have enough power? I know they lock a bike wheel up but a car one is a lot heaver.
Not sure on that, I will do some testing before anything gets fabricated.Quote:

Those are £150 each though, they're very trick, and certainly lightweight at 150g. Just not as light or as cheap as a Hope caliper.
I would want atleast mono 6ti' calipers!!
Yeah what i thought of. Tiny and light but work really well. But yeah the price can be a killer.Quote:

My engine builder has finally come back to me with some figures for the rebuild of my 1000cc turbo engine (the one that's always been in the car). It's due to be rebuilt with steel rods, forged pistons, new valves and springs, custom camshaft etc.
The total bill (with Arrows rods) is going to be about £5,500. It's not unreasonable given the parts and labour involved.
But I have to accept that I simply haven't got access to that sort of money right now. So the 1000cc rebuild is on the back-burner for a while (very much still my plan to do it though).
The rest of the car is 80% ready to race again, so I am thinking of installing a different (cheaper) engine just so I can get out and have a bit of fun with the car.
Just got to find a suitable engine (or donor car) now - XE, LET, smallblock, 8v, 16v, hopefully something suitable will turn up.
The garage floor has now been laid, so once that's completely dried out, at last I have somewhere to work on the car.
