ca18,
are you sure about the spline difference? I was hoping they were the same so that I could use the disc brake axles straight into the vanette centre 1200r/c - I have a series 3 B/B 3.9:1 centre that I won't be using but it's a long way from Melb to get it!!
Cheers

Hey guys,
car is finally ready and two more sleeps before the hillclimb Hope to see a datto owner or two out there to cheer us on .
Cheers
P.S. Boy does that C20 diff look W-I-D-E under the coupe

Datoracer,
I too have had this problem but was able to use standard mount and crossmember with a little (?) modification . Basically cut the crossmember into 3 pieces ( 2 ends and the mount section) bolted it all back in and set the centre (mount) down at the required height and joined the sections together with 3mm plate. Add gussets and an extension to the 1200 mount and once it's painted it looks factory. Pass any rego test
Have a look at the pic - if you need more let me know.
Cheers

Now I agree with you 100% Converted Can you make it to Oran Park in November ?? Let's try and get a crowd there - me,Benny,Converted,B310gx, etc etc. Would be good to see who can get anywhere near Chris' coupe
Cheers

Hey 1200rallycar,
yes I think it was during early discussions on this topic that you warned of too much rear bias. I am running Bluebird front and rear with a Sunny booster & m/c and have found it okay. The only rear wheel dramas I have had is under DESPERATE braking and a readjustment of panic pressure puts it back into line! The new car will have bias adjustment for that reason and also for hillclimb tyre warming .Anyway, still pretty good system for a 'bolt on', that's why Datto's rule - so many possibilities with minimum drama !!
Cheers

B310gx,
thanks for the offer, but I have a 4.6, 4.1, and now a 3.9 . More than enough to keep me amused . Converted, I see where you are coming from as I only run an A14 but it is more the spline size that concerns me on a H145. The extra (slight) axle spline dia. makes me feel a little bit better when using a locked diff. The C20 assembly going in now was behind a A12 commercial so I don't think the horsepower loss will be too drastic. When I raced a Gemini I saw too many early model axles break (similar to H165) but the bigger late model ones (same dia as Torana) were pretty indestructable !!
The next coupe will have a L20 and the H190 will go in there - maybe a bit heavy duty but if Nissan put one under 2 litre bluebirds stock, then the L20 race motor will turn it okay . The extra track doesn't go astray either Thanks to all for the feedback.
Cheers

Hey all,
just a note to let you know that sometimes things just work out . Out searching for new disc brake axles for a diff change, I happened across a ser 3 B/B ultima with a disc brake H190 . Got it from Pick and Payless at Ingleburn for $120 so I'm cheering. Got all the bits I need now for the H190 disc rear on next race car as well as the H165 C20 that is going in the current racecar this week - bit like Christmas (lol). Anyway, that's my excitement for the week - until the new diff and Jeff Taylor springset goes in next week !!!!
Cheers

I agree DD, but since I was building the car from scratch it was opportune to make the opening wider for max airflow. Obviously too major for a quick fix on a road car though !!
I also think there is no such thing as a good second hand radiator Recore it and you know it works - $$ saved bypassing this step soon bite you on the butt on the first bad traffic day in summer .
Cheers

Tyrie,
I have a Gemini size radiator in my racecar but I had the radiator guy use 1200 sides and relocate the inlet/outlet to suit 1200 so I could use standard hoses. Sounds like a hassle but it was no more expensive (I supplied an old 1200 unit to take sides from) and he had Gemini top and bottom tanks in stock. I also modified my support panel to look original (ie widened the opening).
Little bit of scratch and think but the effort is worth it as my car NEVER runs hot with the new setup. Good luck !
Cheers

Hey ISL33P,
good to hear you will call by. We will arrive at the venue about 7 - 7.30am to set up and get our spot but nothing really happens until say 10.00 am so sleep in and come out whenever. You can mingle amongst the cars and check them out so no worries there .
Converted,
sorry to hear that you can't make it but I understand the dramas . A lot easier when you have your own trailer and everything is finished though ! Hope we can see you at the next NSWRRC supersprint in November. Should have some good pics for all on Sunday night .
Cheers.
