My Xmas present to myself was to sit in my shop and weld up the intake for my engine. Just after cooling I set the head on the block for a few pics.
My original design was to use the throttles from a Yamaha FX140 watercraft. A few days ago I decided to make a big change to what throttles I will actually use, this will be seen later.
This first shot shows the angle the runners are at, these are with the Yamaha throttles in place even though they will not be used.
Image

A couple of shots with the throttles in place,

Image

A close look back at the first picture you might notice the flange for the throttles was not welded. I decided I will be using Suzuki Hayabusa throttles instead of the Yamaha ones. Both throttles utilize a 42mm port diameter, this works nice for this engine to set the port velocity but my calculations were originally to go with a 45-48mm throttle for the expected power output. Well I had been trying to justify the 42mm size of the Yamaha setup but after pulling the Suzuki throttles off a shelf, they look to be better suited for this project.
So the intake was actually made to use rubber mounted throttles,

Image

Image

A look down a port, remember these have not been blended yet. I think the air will be happy to go in there.
Image

My next step will be to disassemble the Hayabusa throttles and change the spacing for this application.
Nice thing about a real day off is that I can play in the shop instead of work In the shop. Well my wife does not see any difference between the two, Turns out to space the throttles I am going to buy some different material, tough to do on a holiday. But I decided to put the valvecover in place and hang the Hayabusa throttles as a mockup.

Thank you Todd, The clutch is from Quarter Master, It is sized nice for a 215 disc. This is mounted on an Aasco flywheel.

I will get the spacers in the throttle bodys in the next day or so but will probably hold off on the velocity stacks till the engine is on mounts and I can verify how much room I have for filters or plenum.

This engine is going into an early RWD Galant-Colt. This forum does not have a project section so I intend to present this once the engine is actually in the car.

Lovely set-up! What kind of power are you looking at with this set-up? Powerband range?

My design is to enhance power in the 5-6K range without restricting the top end. The engine will be in a moderately light track car, 875 Kg with cage. I build to achieve as wide a powerband as possible. I do not really know just what the actual power will be when I am done. I would hope to see the high side of 180 Hp.

I have had a chance to get started of the wire harness for the engine, Keep in mind this will be a RWD setup so it may look odd to some.
Here is the donor harness I bought to get parts from,
Image

And after disassembly to get the main sections I need from it,
Image

And here is what I am working towards, A Coil on plug ITB injected system, This is the initial layout, obviously allot more to do,

Here are a few pictures of the first trial fitting in the car I am building. The car is a 1973 Dodge Colt, this is the first gen Mitsubishi Galant, or 16L in NZ.

And a few more pictures with the stock intake set in place so I could estimate what I have for fitment issues. These shots were taken back in November before the snow settled in here, at that point the engine was not on mounts yet, still is not. But I learned enough to get going on the conversion of the engine to RWD started in the shop.

I am going to be running an oil cooler up front and decided I will also run a remote filter. With this in mind I installed oil outlet and return fittings.
Image

The alloy sump on the engine interferes with the steering linkage passing under it, I thought of trimming it to fit but chose to keep it for use in one of my Mirages in the future.
I also decided I am not going to buy a 4G93 Mirage oil sump and still have to cut it up to make what I need, so what you see here is the top flange for a fabricated alloy sump that will have kickouts and trap doors. I gave thoughts to using a dry sump system as I have run in previous Colts but I just want to keep the weight down.
Image

Here are a few shots of the initial work on the sump. The sump will be fully baffled with trap doors and windage trays.
This is formed from 5052 alloy in .125" thickness, should be plenty stout.
