Cutting and dicing the A series

[jeremiahnz]

Hi Guys,

Just looking at my A15 conversion into my Datsun 410, and I need more space to get either the supercharger or alternator where I want it.

If I can trim the block breather pipe and the water inlet this would help. Has anyone cut these down before? Any issues or advice?

The cooling inlet on the a15 has two small inlet/outlets and one large one. I have never had a complete A15 so can someone confirm if the two small inlet/outlets are to/from the heater and a water choke on the carb? This is my guess but could be totally wrong.

To maintain flow to the heater I was looking to use one of those water temp gauge sender adapters but instead of putting a gauge sender where you typically would, I was going to get a screw in fitting from someone like Ash Air.

Thanks in advance for any info

You are on the right track with the heater pipe, but you may consider flow, having it on the inlet causes circulation so you may want to use a set up like the B110 1200 which had a junction into the bottom hose. Someone posted a J spec Sunny race car on here recently with the inlet cut back really short, hose went right to the block, no problems with shortening it as far as I can see.
One model of a series also had a short right angled breather, may have been a van I think, these breathers are only push fit so are easy to remove and modify.

Just cut off a few cylinders

thanks for the replies

Yeah that is what I was looking to do with the heater, utilizing a water temp gauge adapter.

Are the water inlet and the block breather pipes steel? I presume I will need to weld a collar around it to keep the hoses on?

Now that just may work. Got any more pics?

Yes they are steel.
I've run cut down ones without adding a rib of any kind to help keep the hoses on. So long as your hoses are in good nick, and your hose clips are the correct size and in decent condition.

Is that a front dizzy or mid dizzy, it looks like a mid oil pump.

Its a front dizzy, the backs been chopped off, you can see the plate at the back goes all the way up to the back of the head. Its really cool, I heard about a guy who did this to a mini A series and got over 100 horse with it, not bad for 500cc considering the stock 1000cc only has about 80 hp from the beginning.
