I'm looking at possibly selling my TT conversion Stealth. I have no idea WHAT its worth, but I don't want to sell it to some jackass kid

I met a few of you last summer, but I will be posting picture tomorrow afternoon, and anyone in the area is welcome to come check it out.
Background behind the car: Mykiss sold me a shit TT engine, had it rebuild by Don's Machine Shop in Kenosha, along with the heads, bored 30 over, valve job etc. Also rebuilt turbo's, with the original set I have. The car was also converted from an Auto to a 5spd w/ a newer clutch that was installed by a member on the boards from Milwaukee Mopar.
Car currently has 123k on it, interior is in good shape other than the bolster on the driver side, shows some wear.
The only reason I am selling this is I can't get the damn things to pass emissions, its running a fed spec TT ECU, has a WB02 installed, SAFC2 w/ boomslang harness, palm datalogger, and I also have a spare cali spec ecu. I have gotten CO, NOx to pass, but failed HC by 1GPM, after sitting in the driveway for months I've given up. I have lots of spare parts, including the original NA 10:1 engine, the NA heads, the auto tranny etc.
I will have pictures hopefully tomorrow, but please feel free to PM me questions, or call me at 262 716 7444. Car runs great, just need to re-set the ISC and TPS after installing a diffrent throttlebody =)
Asking $4k OBO.
Thanks!
