I got round to making up a mock-up inlet manifold. This fits but I am not sure which way I will connect up the 2 parts it will be made from, I tried making it in one piece but unless I let the machine run for hrs its probably a waste, as there will be no real difference, I will let the pictures do the rest of the talking.
Fitted to the engine with the throttle body’s on.
Plenty of clearance for heat to escape.
The std injector loom of the engine fits the injectors, tidy, It will keep it factory looking.
I will make up a new set, there are a few small changes I want to make, I think I will add a groove for an “O” ring seal instead of a gasket.
Dropped the engine/prop out this weekend, and have a quick trial fit of the E46 cross member, Its fair close to bolt right on and the wish bones (E30) fit as well. I think the track is slightly wider, I didn’t measure the width between the hubs before I took it apart, but from a visual its wider, handy for some extreme camber.
I lifted the car over the engine, easier in my opinion, ( I don’t have a lift).
E46 sub frame offered up;
E30 wishbone on;
Looking at how this fits and the chopping required to fit the engine in, The E46 subframe has the engine way too far back towards the bulk head, and the track would be f^%ed up, the E30 sub is to only non cutting option with the correct sump and oil pickup, Option B would be to make a sub frame using bits of an E30 one to clear the sump on the engine, I prefer to leave the engine intact, multi- valve sumps seam to be scarce.
I will see how I get on.
Offered up the engine and gearbox combo today;
Fits in fairly well with plenty of clearance on the inlet side.
The subframe issue can be seen here, I have the subframe aligned up for a quick view.
There seams to be plenty of clearance using the stock M52tub28 exhaust manifold. The steering UJ should no be a problem.
I am using the gear shifter position to place the engine, The gear box is the same length as the E30 one.
I have decided to cut the standard subframe and build around it. LHS.
I offered up the steering rack, the RHS subframe side is longer and retains the rack mount.
The E46 rack has the pipes towards the front and fits better. E30 one to the left.
E46 rack engine clearance.
I move the rack position on the subframe 20 mm to the right and 10 mm forward and 5 mm down, You can just make out my effort at a mount point, (tacked up for the moment). the move centers up the steering rack and adds some extra clearance.
I have the hubs back on connected up the steering rack. I had a small bit of adjusting to the track rod ends, it seams the E46 rack is 10 odd mm longer. Easily taken up by the rod ends. Next thing is to sort the subframe.
