Idea, Probably Completely Stupid And Wouldn't Work But Hey, A Few Opinions Can't Hurt Right?

Hey guys,

I have been reading around the NA forum and been seeing the talks about the famous combination that is the RB30/25 hybrid. Which got me to thinking, would it be possible to put a VQ35DE head on my VQ30DD, not saying I would (would probably change the engine instead) but just in theory... would it work? would the injection be a major factor? new ecu would obviously be required, and such but I'm also curious do the run the same block (not including stroke and bore properties obviously).

Cheers for reading my insanity, have just been scratching my head wondering if it would be possible, if RB's can do it why cant VQ's haha.

PS. no I don't plan on doing this it is purely out of curiosity.

No one gonna touch it?

Just buy a VQ30det and drop it in with a 3.5 ecu. Much better engine and no cams to worry about then.

[Kolossus]

yes indeedy but this does not help my curiosity dude haha

[scotty nm35]

So buy one and see. The 3.0 has the same sized bore as the 3.5 so it should work fine.

Probably would have to change to a 3.5 ecu aswell correct? (different injection on the head?)
