So here’s a build thread on my 1200 coupe, for those that are interested.

1971 Datsun KB110 1200 Coupe. A12, 4 speed, stock standard.

I brought this 4 years ago, from a guy who rallies these over in New Zealand. This car was a spare ‘shell’ he acquired, but as it was 95% complete, with live registration and plates, he on-sold it to me, as it was too good to cut up for spare panels.

Here are a couple of photos below, of when I brought it June 2007.

More to follow…

Yeah I was originally going to get some Alloy CHS and crush one end as you suggest.
couldnt get the size I wanted though, so had my tubes machined up from 2" billet.

I have machined my inlet tubes, to kind of work like a venturi, and also reduce down to a more "mild A series" choke size. I have a machined flare at the end to match port to the 43mm bodies, and have enough size in the pipe to match port the oval shape at engine end. Have to transition Ø43mm to 38x32mm oval size some how. I think I will end up with Ø30-32mm in mid part of my tube.

Yeah thought it might have been you I got the inlet flange off - small world when it comes to Datsuns!

No I am not sweeping forward, sweeping them upwards a bit more (15° above horizontal)

Yeah I could start a build thread, tend to do most of my Datsun "on-lining" on nzdatsun.com, but I could have a bit more of a crack on here :) might start a summarized version, since its been about 4 years.. and still I have a 90% panel beated shell, and a garage full of parts....

heres the photo of the motor with the ITB's mocked up

Note I am running enough angle on my inlet, so I can flip the whole assembly, thus getting TPS away from firewall, and discretely hiding the throttle linkages underneath, to give clearer room above for fuel rail etc.

my original setup pushed the fuel rail hard up against the throttle linkages, as I didnt want injectors too close to inlet, to give chance to atomise the inlet charge, but didnt want too long as I wanted to keep trumpets aay from strut tower, and also optimise the inlet length (I calculated I think 290mm to be about optimum, from valve and trumpet inlet)

Good to see I am not alone with this wee challenge.

Been working on building a 4AGE ITB setup for my A15 motor for my 1200 coupe restore for the last 18 months or so on and off.
Think I have got pretty much all my bits sorted out, just some wiring, fuel lines & fab work on the manifold to sort out.
First Photo shows a mock up of the assembled ITB setup (will be abut 5° steeper inlet angle than shown).
Second photo shows all my bits; 1) 10mm Laser cut inlet manifold (ex Ebay AU), 2) Custom machined inlet tubes (yet to be match ported), 3) Bosch “shorty” injectors, and Custom fabricated injector pocket tubes (ex Ebay USA), 4) 6mm Laser cut ITB mounting plate, I had made locally (yell out if anyone wants the DXF file), 5) blasted & cleaned up 43mm Silver top 4AGE quad bodies, 6) Techno Toy tuning T3 red anodized trumpys (yummy).

Get my car back in a few weeks from the panel beaters all going well, so will trial fit up motor, wire up the Megasquirt, and hook up some juice etc, and do final fab work on the manifold.

"A15 +040cast pistons & rings dish (new) $250"

Hi interested in the above,
A) How deep is the dish in these slugs or can you give me the "CC"?
B) What brand / part Numbers?

I have an A15 ex race motor, running A14 Pistons (unsure why, maybe they have have crowns machined down for higher CR?) but one pistons is cracked, and two other have skirts broken off...

Looking for cost effective replacement set of pistons .040" / 77mm

Also remembered I have a Set/Box of 4 (NOS) Datsun/Nissan A-12 B110 1171cc (.020 oversize)

Repco Pistons with rings and Pins, Part#RY2562 0.20'/.50mm

Surplus to requirements, as I am getting rid of all my A12 stuff.

AU$150 delivered
