hey mate, yeah i just had a similar problem in my r32. it ended up being the coilpacks. it was getting upto 2500rpm and then just spitting and stuff and wouldnt let me go any higher than it was really frustrating . we pulled the coilpacks out and 3 out of 6 were dead replaced them and havent had a problem since

try your spark plugs mate, my 32 did that it was anoying as hell. mine was fine in the higher revs just a pig as it was comin up between 2 and 3grand, so i just swapped out the plugs and ran sweet as butter, just make sure u re-gap the plugs to 0.8mm otherwise itle missfire a tad on idle. i also left my valley cover off to keep the coil packs cooler
