Hello all.

My name is Tom and I am a new member. I have been lurking for a while. I am planning an A15/5 speed build for my 1969 MG Midget and am making several plans for intake/carb combinations. I found the thread by member TnPshow A-Series Manifold Templates for Autocad - Come n get 'em. Just what I needed! Except the "members.iinet.net.au"-based links were all dead. Since TnPshow's member email is also from that ISP and since his member profile shows his last post being May of 2010 I don't hold out much hope that he will see this post.

What I am looking for is a copy of the CAD file for the intake and exhaust flanges for the small oval port H89 head. This head was OEM for 1980 A14s in the 210 and I snagged one recently to use on my 1982 A15 build. I plan to mod the factory intake to take a side draft carb of some sort (I have a 38mm Lectron) to get it running and broken in, then I will probably move to a twin HS4 deal. There may be other plans or options if I can just whittle parts out at will. Having the CAD models will make things much easier.

If anyone has the same or similar (later-style intake flange) intake and exhaust flange AutoCAD or Inventor (or DXF or STP) files could I get a copy? I have access to Inventor 11 and below.


On edit, eye candy:

First welcome,

You may or may not be aware that there is a twin carb set-up for the A-series engine, the GX manifold and twin hitachi SU's.
Getting that would save a lot of work. Now of course you may have a collection of SU's and manifolds in your MG stash and want to experiment. I would love to see the progress of your project, I've got a buddy who has a 68 Sprite he's working on, I tell him he needs to come and grab a Datsun engine from my garage. I do happen to have a an extra A-Series GX manifold lying around that I likely never use if it will help.

I have the dwg files of TnPshow .

Thanks you! Email sent.Quote:

As RallyTwit has mentioned twin sidedrafts are already available if need be but since you are using lectrons
which are like bike carbs you can splice a stock manifold
for the flange and weld the tubes to is you need and
reinforce bridges like on turbo manifolds using flat plate.

Yes, I have been pondering more than one mod to the stock intake. In fact I have it on my list to get another one the next time I see it at the junkyard. But I also want to keep my options open in the future. I might try the 4 carb setup using bike carbs. I will eventually get around the EFI. I plan to have some fun with this engine and playing with carburation and induction is one good way to do that.

Here is one guy who modded the stock 210/310 intake to take two HS2s.




I plan to do the same but I will have to modify it to take flanges for HS4s.

you can also use the twin weber manifolds this way
