2003 Ba Xr6T (Issues, Questions And More)

[hackthefrags]

Hi XR6 Turbo Forum Members,

I just recently purchased a BA 2003 XR6 Turbo with 180,000 on the clock. This is my first turbo, my first Ford and I don't have a vast knowledge in regards to engines (just what I read on here since I bought the car a week ago)

Modifications: The previous owner had a full gearbox reco done at 179,500 (with 1 year warranty), atmo blow off valve (with custom rubber pipe from intercooler), 4" turbo back exhaust, cold air intake with K&N pod.

Car is running stock PSI (5 from boost gauge)

The Issues:

1. On a cold start when accelerating at low speeds it feels like its misfiring - very weird feeling and very jittery. After around a minute or two it sorts itself out, but its concerning... I'm not sure if its the precursor to larger issues.

2. The coolant reservoir is spitting a small amount coolant (a fine mist) from one of the two small nozzles (connects to a thin rubber hose that leads down to the radiator I think). I have purchased a spare coolant reservoir and going to have a full coolant flush, swap of reservoir and coolant refill in about a week (quoted $100 for labor)

Questions:

1. Due to the increased air coming in and air going out, I would assume that I should get a custom tune done? I got a quote from BTA Motorsport in Belmore for $880 (compared to Tunehaus' $1790). I am wanting to increase the boost to 8 or 9 as well as ensuring the ECU is utilizing the airflow.

2. Based on the above, would I need new injectors and valve springs? If so, how much do these usually cost?

3. I'm currently getting 19.6L/100KM which is huge (first tank of petrol since I bought her, mixture of squirts and standard under 2000rpm driving). What is the best way to bring this figure down? Will a tune help much?

Thank you all for your help in advance.
