My r34 rb25det neo has decided to develop a strange issue where I will be drifting and when I shift gears from 2nd to 3rd mid drift it will stall out just for a second causing it to bog down. Initially it happened rarely at the start of the night but got progressively worst as the night went on. It got the to point where clutch kicking it in 3rd (after having shifted 2nd to 3rd and had the stall out) would cause the same issue to happen again rather than for the car to start hooking up like it had done earlier in the night. I went to pits to try and find any potential air leaks or something along those lines but could not find anything and the car idles perfectly beautifully does not hunt. After being in pit for about 10 mins took it out for a run and it seemed to have no issue at all. Went for another go and the issue was back again. Whenever I drove normally ringing out 1st, 2nd and 3rd gear there was no noticeable issue it only presented when I was drifting. Engine mods are as follows: Nistune 3inch turbo back exhaust Hypergear g2.5 Bosch 550cc injectors Oil cooler FMIC 52mm Alum rad Bosch 023 fuel pump Still running recirculating BOV I feel a likely culprit could be the fuel pump being on its way out. Does anyone think a fuel pump that's starting to run out of steam would present with these kind of issues? Another option I was thinking was that my recirculating BOV could be leaking air out as some of the piping is a bit average and this could be a big enough difference for it to confuse the ECU as it doesn't see the air that it expected to be there. I really wish the issue was something more obvious/severe as it seems so vague I don't really know where to start and unfortunately don't have the money to just start changing everything (crap job and going back to uni). In the end it is my daily and still drives perfect for daily duties at least at current.
