3.0l to 2.5l swap
I just searched threads pertaining to the 2.5l jdm engine and us 3.0l eng. My question is can the 2.5l be interchanged with the 3.0l with no mods with ecu timing or vacuum sytems? The thread mentioned this but did not finish with the full info on the swap?

Build and boost the crap outta the 2.5 and do it. heheheh It would be different for sure. You'll likely need to do some 'modding' to get it all in correctly.
2.5 L @ say .... 35 lbs boost! Oh yea!

I asked because there is a 96 max with one in it at a junk yard considering the engine is still good with 75000 for $200 why not? Googling the 2.5l japanese version it reads that it can be done with no modding or switch out of sensors. I would only lose a total of 10hp but also there are mods that I can do that 2.5l can get that would kick a 3.0l _ss the ratios are nearly the same but the 2.5l is considered the racing version. Now this is base off a couple of searches I've done so far. M-town baby!

You should be able to run it with the stock VQ30 ECU, AFAIK.
Is this a local yard to you, where you've seen it?

yes at a local junkyard I had to look at it myself but the engine code is a 2.5l. I also looked on ebay and there is a seller who is selling that same engine for about $500.

Most likely scenaro - Someone did a MEVI conversion and imported JDM MEVI from a 2.5litre car and use the 2.5 coilpack cover
I've had the 2.5l and 3.0l both with factory MEVI - Obviously 3litre is better

will get pics when I can get back out there today is raining. I guess when I look at it again and really check it outI will see then. The metal firewall cover and the coil cover both read for 2.5l Could be one but I'll check TKO sports here and find out some more info

Either it's a Cefiro, or someone's been swapping out identification plates...and 99% of people aren't going to put a JDM plate on their car just to have it read VQ25DE.

OP: Why do you want to downgrade 500cc?
Boost it if that's your plan.
Hasnt this already been covered before? I know Ive seen pics and discussion of VQ25DE on this forum more than once before.
