After measuring the ABS mockup- I ordered a polished aluminum pipe 45 deg bend and cut the legs to size. Fits pretty nice with the silcone connectors I picked up as well.

The intercooler was build and fitted last year, with the intent I would work out the pipe routing "later". I guess it's now later. I am starting with the "cold pipe", the intercooler to throttle body. In order to limit the pipe bends, I needed to dish out the inner fender. That new plasma cutter sure comes in handy! I am modeling the pipes with ABS first, then I'll bend and weld the aluminum pipes. This side will be 2.50 diameter, with a single 45 deg bend in the middle, a 45 deg coupler at the intercooler, and a straight coupler at the throttle body.

I decided on a log type manifold- not fancy, and not really meant for high HP numbers at high rpms, but definitely OK for what I am doing. If this becomes an issue later, I can have a tuned, equal length manifold built; but that will run close to $1k. I purchased this on line and it was all welded up except for the turbo flange. I needed to position the turbo, cut the hole and weld the flange on. It's tacked together at this point, until I make sure all the parts around the turbo have clearance. I already cut the firewall for the downpipe, and may have to bump the inner fender a bit more. And of course the steering linkage is still a question (for another day).

The motor mounts were purchased from Michael Spreadbury, who installs SR20 motors in Datsun Roadsters. He has some very impressive installations, and fabricates and sells some of the custom parts necessary for the installation. I needed to make some modifications to use his motor mounts, but they are beautiful parts.

Engine Repositioning

I measured the position and angle of the engine. and found that it was offset by about 1/2" and the angle was incorrect (should be 5 degrees toward the left side). I was also concerned about the engine mounts I had installed- the frame side was welded directly to the unibody, which is only 20-22 gage. I came across a set of mounts to install an SR20DET in a Datsun 1600 Roadster (online), and I figured I could modify them to fit, so I bought a set. The right side was a drop in, the left side needed to be modified- I combined the stock mount with the new mount. I also figured a saddle mount on the frame would better distibute the engine load, so I made the frame mounts from 2" angle with welded plate and gussets to mount the mount to. These were then welded to the unibody frame; When the mounts compressed the engine is now in the correct location, with about 1/2" between the cam cover and the hood.

I added a conduit to the front wheel well on both sides to run the wiring as well as the hood latch release through. This should keep the engine compartment free of extraneous wiring.
