Comments: Cylinder 4 coilpack was showing its age and intermittently misfiring. Didn't get in the way of tuning so we pressed on but it'll need to be replaced. Also broke the welds on the turbo internal wastegate midway through a pull but we were able to wedge a screwdriver in the actuator arm to keep it shut and after that we had no more problems finishing up. Will get a bracket on that actuator this coming weekend to hold it shut but until then the janky screwdriver fix is holding solid!

Overall I've very impressed with the car and the little VF39! E really woke this thing up!

Yes of course I can see that the turbo is too small for this motor and it can't hold power up top but for now this is more than enough for me and has really freshened the car up. It's a lot of fun on the street and in the curves. Should be an excellent setup for autox.

Built shortblock, heads, and a bigger turbo (thinking about a Blouch Dom 1.5 XTR right now) are in the future when finances allow.
