Update....
I've changed the plenum design. I wasn't happy with using the existing TBs to mount the injectors. I would have had to put a sharp 90 deg bend on the runners in an attempt to keep everything under the hood.
I've managed to work out another design which fits under the hood without any sharp bends on the intake runners. Here's how it went together....
The bellmouths arrived. First problem was to work out how I can make them stay connected to the head under boost.
Here's the standard head mounts. You can see there is a recess to locate the base of the throttle body.
I used a bead forming tool on the bellmouths to make them a tight fit in the existing head mounts.
Aligning the bellmouths on the base plate. A small amount of machining to make them fit snug.
Starting to take shape... It's 6mm plate. It may be overkill for 2 bar boost, but I'd rather build it strong, than have cracked welds. Besides I might want to run more boost
Trial fitment to the head.
Matching up the side intake.
More trial fitments
I turned four injector mounts
Welded in. It's top feed, with the injectors a firing directly into the bellmouths
Throttle body plate welded on.
Lots of welding later....
I'll be adding two mounting brackets that will clamp the plenum to the head. I've tapped the underside of the plenum with 1/8npt threads for vacuum take-offs.
Mission accomplished. No alteration to the hood necessary.
Made up a turnbbuckle with threaded inserts. This is replacing the chassis member where the turbo is fitted.
The turbo filter in place. I'll fab a heatshield and there will be a side intake duct on the passenger side.
I made a custom back plate for the filter as I wanted a 4" inlet to match the turbo.
Started on the hoses. Tiny Turbo feed vs the -12 oil lines.
Next job is getting the rad and IC sorted. I can then finish the oil, fuel, water and air lines.
Then it's wiring and mapping
