Ok. So I was driving on Saturday, and when I gave it a bit (under full boost = 10psi) it would hit a wall kind of like boost cut at 4500rpm for 5 secs then kick into boost again.
Checked over a few things that I thought could be the problem.
1: cleaned afm and plug.
2: tightened intercooler piping and checked for boost leaks.
Nothing worked
Was running and driving fine apart from when I put my foot down.
Then this morning I went to start it up and it wouldn't kick over. So I got a new battery since the one I had was a lil old, put it in and still no dice
All the belts are moving and its just on the point where it wants to kick over, which makes me think it could be the starter motor??
Car was also recently tuned.
Car: Silvia
Engine: Rb25det
Mods include, splitfire coilpacks, turbo back zorst, Apexi avcr, apexi safc, platinum plugs, intercooler, brass button clutch, nothing major.
Any suggestions would be great.
cheers, Ben
