ka24de slow... - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

hey guys i recently bought a rebuild ka24de in nov last year and up until last month my car started to run really slow when it revs up high. it pulls really hard from 1-4k after 4 it seems like it just dies out and its only reving. this started after the raining season, so i thought it was an electical prob and might go away once it dries out.?? last week i went to a drift event and i notice i had to clutch kick a lot!! bc the power just keep dying, it was really hard to hold the drift due to the power loss? idk whats up with it any ideas to what can cause this prob or solutions??

Thanks!

Plugs, maf, and ignition timing could be the problem

If it pulls hard in early rpm than comp should be fine, check the ohm of injectors also, and I really thing it's the ignition timing, fully advance it drive it and just work ur way back retarding it, and make sure your maf isn't able to move one bit bc that was my problem, when sideways the intake is moving and the maf is getting thrown off so it bog
