Love it with the zender valance! If I may ask what happened to the Jimmy hill lip? Why switch?

SUB'D. so cool to see a euro bumpered IX in the US. Been considering it for my 88 coupe resto.

Cool project. Lots of work ahead of you! It's weird to see the euro aluminum bumpers, but then see the NA grill surrounds. It's a cool car with an interesting background.

how does drive with stock cam?

It runs pretty good with the stock cam. Quite a bit of torque. I haven't run it much above 4000 rpm but it pulls up to there. I'm sure my altitude isn't helping things. Only about 500 miles on the engine now, another oil change and I'll be getting the whodwho MS2 setup.

You guys may have seen this a couple years back, but it is finally on the road.

Some quick information on the car.

Its a 1986 325iX in diamond Schwarz Metallic. Looking up the vin, it seems to be one of the first iX's produced (11/85 with production starting in 10/85). The car was brought in to the US through Texas in March of '86. It didn't pass inspection (federalization) until October of '89 according to the VIN report. It has lived in Colorado ever since and passed a few hands until I found it.



It was the euro M20B25, so 9.7:1 Long Skirt Pistons, Motronic 1.0 073 ECU, taurus red leather sport interior, ski bag, ac, 13 button obc, sport mtech 1 steering wheel, rear headrests, power windows, power mirrors, power sunroof, euro bumpers, iS rear spoiler, front and rear fogs, and the Jimmy Hill Chin Spoiler.

The guy I picked it up from messed up too much to detail, but I made a few changes in fixing it.

I have some 24# injectors I was planning to run but I am having trouble with my whodwho MS2 Extra PNP MS2 setup. I think I need to change to a Variable TPS from an M5x engine to make it work correctly.
