Guys I finally have my injection manifold given to me by a friend. It is the same as the one in the engine,driveline,fuel photo album.
The throttle body has 2 butterflys like the standard carby and they don't look much bigger. My friend used a Camira throttle body instead which is bigger but still twin throat which
makes it hard to get good and neat piping hooked up. I picked up a Nissan RB30 Skyline throttle body today which I am going to use instead. Should be plently of flow for an A15. It
has about a 50mm butterfly with a tapered inlet that is about 70mm.
Will try and take some photos as I go but it will be ages before I could post them as I don't have a scanner.
So far its only cost me $50 (the cost of the throttle body).

How hard do u think it would be to make up a custom fuel injection manifold? If i were to use all the fuel plumbing from a stock injection manifold and make up the pipe work and
possibly use it with a turbo and aftermarket computer?? I know Andy (Ernstak) is planing a turbo, injection setup but was just curious as to wether this would work? I might try it
one day if its worth while.

Scott, I hope it will work since I'm planning to do just the same. I'm using a dual Weber manifold as a starting point for mine. I'm planning to fire the injectors straight down the throats
of the manifold for a more direct shot to the valves. There are several people who make weld in bungs for injectors so you could convert just about any manifold to FI. I got mine from
Electromotive here in the states but Simple Digital Systems in Canada has a better price. I also like SDS's computer better since it doesn't require a laptop to program. Am I rambling?
Sorry. Tim

Scott I was looking at making one up until i came across this factory one for free. The only thing I don't like about it is the size of the plenum, I think it could be a little bigger but with
a turbo or supercharger it should be fine.
I am looking at running a Perfect Power computer from South Africa. They are not as full on as a Motec for example but seem to have everything I require and are $795.
With your welding skills I don't think it would be to hard at all. When I was looking at the wreckers the other day I came across a manifold that had some bolt on injector mounts. I think it
was a Camira or Rodeo one, I'm nearly sure it was Holden. It struck me a useful as the mounts looked like the injector just poked through a hole and the whole mount held it in place and bolted
onto 2 lugs. May be easier than getting some of those small injector plugs welded in.
My ideal manifold if I made one up would be to have runners turning up 90 degrees to get away from the exhaust and have dead straight inlet paths. Even the factory one curves in to the centre
a little. With them straight it would leave more space for a better bend on 2 & 3 exhaust ports. Then I would have a barrel style of plenum at least 4 inches in diameter. I would make it in 2
halves but only so I could weld some ram tubes onto the runners on the inside of the plenum to help flow. Air does not like sharp corners. If it was a high horsepower motor particularly turbo
I would mount 2 wrecker sourced throttle bodies (eg decent sized factory say CA20 or RB30)in the side of the plenum in line with each pair of cylinders.
If you are good at welding I would think the hardest part would be lining up and welding in the injector mounts.
I think its definately worthwhile if you can get the parts cheap enough or make them cheap enough.
To have 150hp and a perfect idle and no cold starting problems etc has to be worth it. That computer I'm looking at can fire a single coil in which case I have an E15 dizzy or it can fire
multi coils (eg 4).
Anybody know what type of sensors etc I need to trigger multi coils.

Yeah i would have figured it was pretty easy. I just wasnt sure about all the injector bits and plumbing. I might try and make up a EFI Turbo A15 out of one of the spare A15's i have one
day. I have all the equipment and pretty much know what im doing its just a matter of money and time! For now im directing most of the cash flow towards the 1200s new gearbox, clutch and
diff. Much more important than sqeezing more HP out the A series!! cya

Hi all
Has anyone here used an 8 bolt bluebird diff centre on their 1200 ute?
Was it a straight swap/bolt in that required no alterations to the
tail shaft flange etc?
Is this diff of a series 1,2 or 3 bluebird
Thanx

Yep, it is a straight swap i did it about a year ago, they are out of series 1 and 2 only , the series 3 diff is a h190. the bluebird ratio is 3.9:1 which was better for
me for hwy drivin.

Yep, 7 years and lots of burnouts later...it's still there. No mods required. Even with a CA18DET.

It's an early model Bluebird one. They appear to be a neater casting, but as for strength, all I can say is that it's good enough, certainly for everyday driving, for a race machine,
it may not be enough.
