Man I wish

120k kit - number one priority
New spark plugs - NAs take NGK PFR6B-11, and do NOT use any other plug. This car is very picky about that. It runs great with these NGK plugs and these plugs only. I can't remember which plug the TT takes. Are you NA or TT?
New fuel lines
Set timing with CAS and timing light
Check electrical connections for corrosion and clean if necessary

All these topics have been covered before on here, so go ahead and search em up! Great place to get parts is http://www.importpartpro.com

Stock and slightly modified TTs take the PFR6B-11B.

The 120K kit is a must do, with no maintenance records. If the timing belt goes on the VG engine, you're in a world of hurt. Biggs is right, IPP is the best place for OEM and many performance parts:



New fuel hoses and filter
Fresh oil change with Nissan filter or pretty much anything but Fram
Set timing as noted above
Also run the ECU diagnostics to find out if there are any codes (not all codes trip the CEL)

Do all of the above and clean every connector on the motor (injectors, coil packs, MAF, CAS, PTU, IAC, everything). After the 120k kit, it is probably the next biggest thing. Also, look at replacing the intake valve cover seals and resealing the VTC solenoids (they mount in the back of the head under the intake valve cover).
