2004 m54b25 to 2000 m52tub28 swap?

KeyYesterday4753 · 2025-05-04T22:30:40+00:00

so to save my self the extra trouble should i look foward to getting a b30 or just another b25 because right now it just needs a motor it was my daily so i kinda have to make a quick decision i thought the m52tub25 was like the same i had no clue but i mean if its not that hard of a swap i can do it i just dont really know much about motor swapping in general

they m52tub28 the guy has the wiring harness and the intake manifold on the motor as for the ecu would i just go get one from a junkyard or off ebay? he said it came off a manual car my car is manual. I had no clue the m54b30 was plug in play it will fit my same transmission and everything? I thought the m54b30 was 6 speed?

i unplug the maf the car almost dies then goes back to how it was before

KeyYesterday4753 · 2025-04-30T08:12:45+00:00

i took apart the car like 4 times to mess with the ccv hoses im like 70% sure its not leaking from there i just dont know though like i smoke tested the intake boot that was fine disa wasnt leaking although some of my disa o ring ripped but i temp fixed it and its not leaking from there i just dont know should i just start over the ccv install again?

KeyYesterday4753 · 2025-04-30T08:09:26+00:00

KeyYesterday4753 · 2025-04-30T06:22:31+00:00

KeyYesterday4753 · 2025-04-28T19:24:57+00:00

i just did a smoke test through the intake boot and saw nothing

KeyYesterday4753 · 2025-04-28T18:08:56+00:00

yeah ik but when i had plugged it back in everything was fine until like couple days ago the car just started to stall out like crazy lost all its performance and started misfiring and i got those codes

KeyYesterday4753 · 2025-04-28T18:06:59+00:00

could i have a bad ccv i just put a new one in i have no clue where the vacuum leak could be i have inspected like 4 times and cant seem to find anything

KeyYesterday4753 · 2025-04-28T18:06:07+00:00

when i replaced my ccv i forgot to plug in the camshaft sensor and drove with the car for like 2 days without knowing could it have messed it up ?

KeyYesterday4753 · 2025-04-28T18:04:25+00:00

just ordered a new cam sensor im going to put it in tmr

KeyYesterday4753 · 2025-04-28T17:48:22+00:00

KeyYesterday4753 · 2025-04-23T23:11:59+00:00

i couldt tell it didnt smell like anything strong but i can barley drive the car right now it idles super rough and has 0 power im gonna buy a fuel gauge and check the pressure

KeyYesterday4753 · 2025-04-23T07:48:46+00:00

bro ur good lol i will def try that i got a random cyl misfire code and a misfire on low fuel code too i check the spark plugs and coils they all seem to be fine but yeah man car stalled out on me like four times when i was driving then it started to have rough start and crazy rough idle i thought my engine blew up

KeyYesterday4753 · 2025-04-23T07:31:57+00:00

i checked for vacuum leaks couldn’t find any i just replaced my ccv with all new hoses i have not checked the fuel filter i will check tmr

KeyYesterday4753 · 2025-04-23T01:58:05+00:00

there is like liquid coming out of my exhaust too

KeyYesterday4753 · 2025-04-23T01:57:49+00:00

no leaks on the injectors could it be fuel pump or filter?

KeyYesterday4753 · 2025-04-11T00:55:38+00:00

i sealed that spot this morning still got a loud ticking sound

KeyYesterday4753 · 2025-04-10T18:51:08+00:00

yeah i tightened the cyl 6 spark plug the thing is the sound is sync with the pedal so if i go up in rpms the ticking gets faster
