1993 URS4, bought in may of 2016.

At that time, it had a broken water pump, a bad MAF and a bad internal map sensor in the ecu. I fixed that stuff, and enjoyed driving it for a while, installed a Kenwood head unit integrated to the stock Bose amps. Made several different exhaust systems, didn't like any of them.
Started collecting parts to make it a wee bit quicker. Got an Aeromotive 340lph pump, RS2 replica manifold, Bosch "green giant" 440cc injectors (flow 480cc@ 4 bar which I'm running) a Volvo S60R K24 7400 turbo and a billet wheel for it. Also scored an early Stromung stainless downpipe, and modded it with a flex coupler and a V-band flange to make it easier to work with and less prone to cracking. Got a very large e-bay intercooler from a kid on kijiji for almost nothing.





Once I had this stuff together, I stalled for a while trying to figure out how to tune the Motronic 2.3.2 .
Not a lot of info, and I'm no hacker, so that wasn't gonna happen.
So I got a VEMS PnP

Now that I had all the ingredients, I went ahead and put it all together. Fabbed up intercooler plumbing, flow tested the injectors, made a breather tank, installed fuel pump. It started up on the first crank with the VEMS after setting the injector constant. I was able to get a fairly close base map for an RS2. Tweaked the fuel map quite a bit to get it running strong around 0.85 lambda under boost. RS2 ignition map works well enough, but I really need to get it on a dyno and get a real tuner to set up the ignition advance map to get every last drop out of it. The closed loop boost control really threw me for a loop until I got the PID dialed in. Now it peaks at 2 bar of boost and holds ~1.7 to the rev limiter which I set to 7700rpm.





Next up is 6 speed swap, dyno tuning, brakes and suspension. Still have to make a better intake setup, I'm not too happy about the cone filter 3" from the exhaust manifold, though in 30 degree C weather, my peak intake temps were 38 degrees C under full boost on the drag strip. Picking up a set of H&Rs assembled on Bilsteins today, and I've got my 17z brackets ordered from Brydon Engineering. Calipers and rotors should be here soon as well.
