Guest yogi Posted March 21, 2011 Share Posted March 21, 2011 I'm thinking about trying to swap my vg30 for one of those 3.5l jobs. Has antone done it yet? Can it be done?, I don't see why not as they are basicly the same. Link to comment Share on other sites More sharing options...
Tungsten Posted March 21, 2011 Share Posted March 21, 2011 Go VG33E, you don't need to swap the ECU. Also, Link to comment Share on other sites More sharing options...
MY1PATH Posted March 21, 2011 Share Posted March 21, 2011 the 3.5 Is VERRY Differant. Size Shape engine mounts and locations electronics emissions Bolt pattern for tranny bell housing Etc... Now a 3.3 on the other hand is very close, all the above is the same or can easliy swap over. Link to comment Share on other sites More sharing options...
1980 Posted April 6, 2011 Share Posted April 6, 2011 Thanks for the opinion people. Is the VG33 any better on fuel than the VG30? Link to comment Share on other sites More sharing options...
GoPathyGo Posted April 6, 2011 Share Posted April 6, 2011 I worked on the VQ in my Pathy and am working on the VG in my Fronty. The VQ is more "modern", which means it is more complicated, parts are more expensive and there are a lot more things that could go wrong. It will probably be a tight squeeze in the WD21 engine bay, the harnesses will be different and ongoing servicing may be quite difficult because of space issues. There is a chance you may need to swap the entire cooling system (radiator, fan clutch, fan, hoses) to account for the difference in engine size and heat. I'm not sure whether a VG30 cooling system will be enough for a VQ35. The size and layout differences could also create clearance or position issues for the steering box and various other components. Basically, if you're going to that much trouble (likely a few thousand bucks assuming your time is worth SOMETHING), you might be better off just getting an R50 with a VQ. I've driven both the R50 VQ (GVWR of 4500 lbs with the junk I added) and a D22 VG33 (GVWR 5200 lbs stock) and the D22 never felt sluggish. Fuel economy is going to be terrible with all 3 engines. If it's fuel economy you're after, look at models with the KA24. That's a zippy little thing, parts are dirt cheap and it will run forever. Still not *great* fuel economy but better than the V6. Besides, the money you'll likely end up spending on a major swap will eat whatever you'd save in fuel economy... 1 Link to comment Share on other sites More sharing options...

LOL Though as gas prices continue to rise gas mileage may eventualy catch up to the cost of an engine swap. 1 Link to comment Share on other sites More sharing options...
