Im preparing to do a rebuild on my 00’ infiniti i30 which i may be replacing with a motor off a 01' base model. Will I encounter any issues involving possible differences between engine harness or ECUs between the two model years?

2000 and 2001 are the exact same car, shouldn't have any issues.

2002 2003 and 2004 are I35

01 doesn't have EGR.

NinoBlue

would that make an 01 motor unusable with a 00 wire harness and cause a check engine light? Should i only be looking at motors from my specific year for that reason?

NinoBlue

Correct, the bodies are exactly the same. My concern is whether the harnesses will match? The infiniti parts site says the harness for an 01 was made for 01+ models while the harness for a 2000 I30 is specific to the 00' and older models. Despite this info, i was just curious on whether i could still get away with it?

you can swap EGR **** (and maybe IM, can't remember if it's sealed), but I wouldn't. I'd use 01 ecu lol

uptownsamcv

just use the 01 long block and 2000 everything else.

Reality sucks

I have a 2001 engine in my 95, I only used the block and heads. I just swapped everything over from the 95 engine. Been in the car 6 years with no issues.

Awesome! That's more along the lines of what i should've done. I just bought an identical motor to mine, same year n all. While in search of it though, i was coming across way fresher FWD 3.5 VQ's out of newer muranos and maximas. What would prevent me from swapping newer motors like those into an i30?

NinoBlue

Yea i was trying to avoid having to source and pay for any extra part that wasn't completely necessary to gain. When i upgrade to a 3.5, all this info will definitely come in handy. For now I have to keep this rebuild as inexpensive as possible. With that being said, im not completely versed in all the differences/similarities between all FWD VQs. Where would i even begin with possibly understanding what's needed to swap a motor from lets say a 09' maxima or murano into a 00' I30?

So in theory, could I swap this newer maxima motor into an I30? Whether I frankenstein it or do a full swap, it shouldn't be too big of a job right? I know a 3.5 will fit(hence the I35) but im concerned mainly about harness assembly, ecu/ignition and the transmission fitting.

you would have to wire in a 5.5 gen engine harness ECU into your car, 5.5 gen flexplate + everything it takes to perform the swap into a 5.5 gen. would also recommend Nisformance ECU flash to get the most out of it.

here's the Nisformance swap guide https://www.nisformance.com/Articles.asp?ID=252

transmission fits the same and should wire in the same since 95-03 have the same automatic from what I heard..

No, just convert to 3.0 timing. In fact, I know a guy that has the kit new in box still lol

NinoBlue

Thanks for the link, it's very informative, im super elated now. I did grab that 7th gen motor too. So you're saying the 4speed that comes in 95-03 maximas will mate with a 2nd gen vq35de?

uptownsamcv

3.0 timing?

run the original timing from the dek

uptownsamcv

gers and chain cover?

Engine swaps are cool and all. But my best advice is to you here is to put it back exactly like it is and have a reliable car, I've been in the maxima game a long time and these days I prefer my 3.0. Its reliable. Plain and simple.
