I've heard many times that the VE that came in some 3rd Gen Max SE's were basically tha VG with DOHC designed to fit a FWD application. So does anyone know if thes heads will fit our VG's to produce DOHC as the VG30DE(TT) won't. I know it's Timing chaine, but I'm asking about the headbolts and chambers lining up. If I get a good enough deal I may just try it, but we'll see if one one knows before I spend any money on it.

None have done it that I have seen. I'd say save the cash and buy a better performing engine all together if you are worried about head flow etc on the vg.

But it would be awesome would it not? I think so. [archived image: redface.png]
aceman: (2011-02-09 03:37:35)
not really.
Careless: (2011-02-09 03:45:58)
its a VG30DE with a timing chain, not a VG30E.

If you want its heads, there is no reason to not just run the entire engine. But at that point you're better off getting a VQ30DE out of a 95-99 maxima, there are more of them, plus all aluminum (way lighter), stronger internals, better flowing heads....
dustin87: (2011-02-09 05:43:37)
Oh well, ok. Point proven I guess.
Richard_85ZXT: (2011-02-09 06:08:47)
If it involved sticking with a VG30 and adding better flowing heads then yes, just swapping the whole motor would be easier, but for VG33 applications it would be great. I assumed it'd be more like the VG30DE but was hopeful maybe as uncommon as those VE motors are to find that maybe it got overlooked. Thank you careless, I can always count on you for solid info.

I'm high half the time, so you must have read half my posts.

The VG30ET exhaust manifolds will bolt up, the cross-over pipe will not clear the intake.
The RWD VG transmissions will bolt up.
The engine mounts bosses in the block are in the correct location for RWD applications.
Now make it work in a Z31.
A guy over on HybridZ has fitted alot of other VG parts on a VE for mockups.

VE successfully transplanted in a Z32 which means it work in our cars as well.
michaelp: (2011-07-08 18:25:37)
wtf…lol
I think fitting one in a Z31 might prove to be a bit easier than a Z32, being our manifolds will work....

I'm so tempted to swap out the VG…which is blowing blue smoke. And I have a perfectly find VE just gathering dust.

I'm so tempted to swap out the VG…the VE is my true luv and I know her so wel (have a low mileage VE30DE with EFI harness and ECU gathering dust). And yeah I got a couple o VTC rebuild kits and they they last like how long…20yrs? The trick is in the oil filter…it likes the better flow/anti drain of the Toyota OEM filters. The VG's always seem to be busting up the exhaust studs and I think I have a few busted ones on the Z's driver side I think the inter connecting flex pipe saved the passenger side from fooking up too. My first mod will be aimed at preventing the death of my exhaust manifold studs. The power crazy shite can wait.[/quote:2nhjlc11]
The VE uses the same oil filter as the VG30E I'm quite sure (dont quote me on that though). If it does, just don't use cheap oil filters. Bosch & K&N both have anti-drainback valves.

We got a whole thread dedicated to the filter alternative for it. Both engines use the same filter but for some reason the VTC sounds like a sewing machine at start up with certain brands.

That's me DD man…fully restored and running like a naked virgin :twisted: . I recently added true CAI and copper tank radiator.
michaelp: (2011-07-09 00:25:12)
Yup, I've seen that thread. Still say just use the proper filter from a decent brand, like Bosch or K&N. They have anti-drain back valves.

I wont lie, I've looked longingly into the engine bay of many a maxima thinking things like "coil over plug, dohc, sequential injection, better technology everything, lower miles…" etc.
If the rwd transmission bolts up, and the motor mount locations match, what is the major mechanical difficulty to over come? I could do the rewire job in my sleep at this point.
Someone say something that sounds really hard so I wont start saving money to do this. Is the starter a dead match? No drilling or craziness like with swapping to a Z32 trans?
I don't care about the cross over pipe. If VG manifolds bolt up, that means my set of pathfinder manifolds will too. I actually sold a headlight to a guy with the VE in his Z32. I find the swap
questionable in that car, but more reasonable here, for someone with permanent N/A aspirations.
Augustus Maximus: (2011-07-09 04:18:14)
I swapped my rusted out 92SE into a 90SE so that was putting a VE into a VG shell. I swapped EFI and engine compartment harness, rewired the fuel pump for the more intelligent on and off the VE uses, cut and splice a few things here and there for turn signals and horn and it's been perfect. The top end of the VE is unique…it develops more power the faster it goes. And it uses the same injectors the 4th gen uses.

If you use the Z31 trans, then the Z31 starter will bolt up.
If you use the Z31 turbo manifolds, you will need to fab up a cross-over tube to work and head angles and distances are different. This is assuming you have worked out the upper intake and coolant issues. You could use Z32TT manifolds if want twins.

You have to figure out a new upper intake manifold and coolant pipe routing.

So which is it? Do Z31 manifolds work, or Z32 manifolds? Yes, the flange bolt pattern is the same but oval port vs round port…
Augustus Maximus: (2011-07-10 15:43:28)
Personally I'd fab the UIM.

Sounds like more trouble than it's worth in the long run.
Besides, my friend just got Forza 2 and I built a 240z (fairllady) with 580 h.p., and about the time I took it out for a test run
my desires to remain N/A stayed back on the starting line with the rest of the pack [archived image: tongue.png]
