on a recap. I really really want to do this eventually. But the info in this post is all over the place. What exactly do I need to do this mod right...? Tell me if I'm correct....

VG33E block
VG33E oil filter mount
custom exhaust headers
VG33E motor mounts
VG30E intake plumbing mounts
VG30E head
VH45 pistons
VG30E crank, oil pump and front pulley
machine the VG33 nose down slightly and bore up the VG30 pulley slightly
?????? rings
?????? rods
?????? crankshaft

someone fill in the ???????? and fix any wrong info I have. This is what I've gathered so far though.

 

Ill number this stuff and correct it

#1- Maybe, a VG30 block can be bored to 93mm like the VG33L block can, but the VG33 block is suppose to have more material but the same wall thickness as a VG30 block bored to 93mm.

#2-IDK, but probably the VG30 mount as its easier to service

#3-good performance option but I think not needed. IDK how well the stockers flow but I know they aren't garbage

#4- Doubt it, the 3L and 3.3L are the exact same externally mounts included

#5-plumbing mounts? whats that? If you mean 3L upper intake and piping etc then yea, but its not nessicary to keep that stock

#6-I think the 3L heads are suppose to flow better so yea either way keep them

#7- yep gotta have them

#8-VG30E crank, oil pump and front pulley OR
machine the VG33 nose down slightly and bore up the VG30 pulley slightly option 2 is best but not needed

#9-VH45 rings

#10-VG33,VG30E or VG30DETT rods, really any VG rods, the 3.3L and TT are the strongest

#11- #8 covers this but 3L or 3.3L

The only other thing you need is bigger injectors, from aftermarket, Z32 ones, or VG33 ones, and tuning.

Theres 2 options.

#1-VG33 block, rods and crank, VH45 pistons, VG30 heads, plus all the little stuff like 3rdgen maxima intake or modded 2nd gen, headers, etc the main thing about this option is the 3.3L block, as its a solid

#2-VG30 block, rods and crank,VH45 pistons, VG30 heads, plus all the little stuff like 3rdgen maxima intake or modded 2ed gen, headers, etc the main thing about this option is the 3L block.

It wont be as strong as the 3.3L block, but its a closed deck so its still really strong. I talked to Matt and he said the thin walls wouldnt be a problem for an NA motor. Im planning on doing this, but im wondering how cam choice would affect driveablity and MPG. This is my DD and thats a big factor. Of course I get 12-15mpg right now because I have several fuel leaks and exaust leaks but I cant sustain that gas spendage!!

Im about to tear down one of my VG's (i have 2) and get it bored and check and see if its possible. Can any one donate to help the performance maxima world evolve?

 

something to think about

Christ even the fawking core charge is more than my black car is worth!

 

yeah a 2nd gen owner on here bought his car from a guy that already did a VG33ET swap... He has haltech and a a bunch of other stuff.

 

i wonder how many cv axles and transmissions i could burn with that.

 

Hi all. I was surfing the Net one day when I was just doing aimless research on basic info on Maximas, when I came upon this Wikipedia page. It specifies which Nissan vehicle had which engine. So, for those who wish to seek their replacement engine or what not, here ya go:

VG series: http://en.wikipedia.org/wiki/Nissan_VG_engine#VG30DE

also, at the bottom of the page, there is "See Also" link, to look at other Nissan engines, or if you don't know your engines but know your Nissans, there are categories for cars too! have fun with

 

Ok that was a pointless post

 

Yes theres a DOHC VG, NO it wont fit in our maximas. Thats why the VE was made. Its a DOHC VG that fits in the maximas.

~Alex

 

yeah, I know, there were a few questions about "where can I get this engine and what year" and all. So, I figured ppl in here could use it to find what they want. Right, not all the engines can fit in any car, but, it's always possible. So, if ppl were say looking for the VH45 or whatever pistions, they can go look.

Thanks for the compliment. <--not me

 

One word of advise, dont waste your time putting VG30DE rods and pistons into a VG30, too much work. I wish I would have went turbo instead!

 

Quick question: Instead of doing all the swapping and boring out of the vg33 block and using vh45 pistons; why not just use the vg33 block and pistons as they come? That would give a 3.3L engine instead of a 3.4, but I'm wondering why nobody has done it if the two blocks are externally the same like Alex_V mentioned earlier. I mean, 0.1L difference and it would seem to me like a lot less in terms of cost and modifications. Somebody please tell me if I'm overlooking something.

 

The compression ratio is the large difference. It is higher with the VH pistons than the stock VG33 causing most of the power increase.

 

Good for a turbo though...

 

3.3L turbo = TQ and thats bad for trannys. Id rather have a 6500-7500 RPM VG or VE then a 3.3L turbo. Oh well DD yea...for a race car Id pick something else...

~Alex

 

Briggs & Stratton engines are bad for our trannies (ok, ok... so not really... but you get the idea. )

A 3.3 with a turbo would definitely be a blast. The 3.0 with a turbo setup would be more than enough for a Maxima though. Either way would be fun. If I had a 3.3 laying around I'd probably try it though.

 

I'm in the middle of a VG30e to a VG33e swap. The car is a S12 (200sx) but maybe I can help with some things.

The temp sensor in the front of the head was not there on the VG33, but the hole was. I just screwed the sensor off my old motor.

The intakes swap directly between the VG30 and VG33, so I'm running a VG30 lower intake and injectors with the VG33 (pathfinder upper intake), which does not fit directly under the hood, controling it of the original VG30 ECU. You will have to wire in the idle control valve.

The exhaust manifolds will bolt on, but in my case 2 of the studs on each side where in the wrong locations. The heads have 4 holes around each exhaust port and you can easily move the studs. The VG33 does have thicker studs, the VG30's manifolds fit right over them no problems, but the VG33 studs also have more shoe (or unthreaded area) because the truck manifolds have a thicker base flange. You just need to run washers under the nuts to get the manifolds to tighten up all the way.

Already mentionmed that you can't swap crank pulleys between the 2, so if you want to run stock accessory locations, you have to swap crankshafts. Don't lose your flywheel to crank bolts, the flyhweel bolts are longer then the automatics flexplate bolts, and if you use the flex plate bolts only a small amount of thread will actually go into the crank.

all VG33's come from trucks, so the oil pan and pick up tube is different. You can swap oil pans directly. Now here's the great part. The VG30 and VG33 have totally different oil pumps, they have there pick up tubes on opposties sides of the motor. So you can't just bolt a VG30 pick up tube on a VG33 oil pump.

Since you are swapping cranks, you have the oil pumps off both motors anyways, you can swap oil pumps at the same time. At that point you have no oil filter.. Because the VG33's oil filter is on the side of the oil pump, whereas the VG30's is on the side of the block. The VG30 oil pump has no allocation for a filter. The oil filter hole is there however on the side of the VG33 block, there is a block off plate covering it. However there is no oil filter stud or reflief valve (S12) or oil filter mount (Maxima? not sure how that set up is). You can swap oil filter studs between blocks, and buy a new relief valve, it probaly won't come out with out destroying it.

If anybody wants any pics detailing the difference between the 2 motors, send me an Email

I love my 3rd gen, and I was trying to sell it for a while but now I'm realizing how great a car it is and I think I'm going to hold on to it. Where it does lack though, is power. Its a VG30 5 speed with 201k miles and I'm thinking of swapping in a new low miles top end with a cam. Or maybe a whole new engine with a cam. Right now theres valve tick on cold startups I'm guessing someone neglected regular oil changes and theirs sludge built up, prob scarred lifters and such.

How much HP could I expect from JUST a jwt or wolf racing cam? (along w/ an intake cone and exhaust). I think project pathfinder showed like 20+ hp right?

Also how many RPM is the stock VG30E bottom end good for? Is our 6000 rpm redline for real or just becuase its out of the power band? Rev limiter is way up there at like 6800 right...

This 15 post to post crap is really deterring, sorry, didn't mean to threadjack. I'd just like to hear from people who experimented with cams. I don't want a huge boost in power or huge hit to my wallet. My car already has a aftermarket y-pipe, its not mandrel bent, but its better than stock so I don't really wanna jump to a warpspeed one.

 

What kind of aftermarket y-pipe do you have?[brand name]

 

I'm not sure, it came with the car, I'll have to take a picture of it later.
It looks like its just a revised OEM replacement not any kind of performance mod. I'm not sure if our 3rd gens came with the precats newer maximas have but this y-pipe doesn't have any.

I was thinking about it, and I'll probably just do intake and exhaust and advanced timing and I'll probably be happy with that for a while.

 

i'm eventially going to be doing an engine rebuild on my 91 GXE. i'de like to bore the engine out as much as i can up the compression, grind the cam, bigger throttle body, ect... going to do the works when i do it. but..... My philosophy with cars, especially when doing that sort of work to a car with 212k miles on it is to make it handle and stop before you make it go fast. Working in a body shop i've seen too many idiots who made their car fast but forgot the importance of a good suspension and totaled their cars.

 

can i bolt my vg 30 manual trans to a vg30 dett

 

yes .

 

Yes,but the 300zx engine will have fitment problems into a maxima body,the heads are taller on the zx engine,so unless you like running around without a hood,i wouldn't try it...

BTW,nice to see a local guy in here..

 

well... i've just been given a VQ35DE motor today w/ one blown cylinder. after i fix and build it, i want to swap it into my 91. has anyone tried this yet?

 

No,you would be the first..

 

have fun. show us video when it's running.

 

You'll also need engine management, the stock stuff would be the easiest. But there are other great options, if you take the VTC's out of the equation.

Then you'll need a 4th gen 5speed tranny, oh and have fun getting axles to fit and making 4-5 engine/tranny mounts.

Other then that it'll bolt right in.

If you don't want it any more Id buy the VQ35 off you...if shipping isnt too expensive.

~Alex

 

I'm sure i can make it work. I need an wiring harness and ECM and tranny. I'm not too worried about getting all that yet, I'm pretty sure i can make it work. Worst comes to worst i'll end up with a built VQ35 motor and tranny.

 

How do you plan on upping the compression?

 

I have a couple question concernning my Maxima 92 brougham.

no.1-does the VG33E pistons fit in VG30E engine?
no.2-what happen to the compression of the VG30E?
no.3-does the super charger of the VG33ER fit on the VG30E?
no.4-which manual 5 or 6 speed manual fit on my VG30E?
no.5- what i need to convert my tranmission' Drive axel ect?

 

1. no
2. nothing
3. with modifications yes
4. one from a third gen maxima
5. depends on which trans you use

 

#1 maybe. Your boring out the stock VG30 bore by 3mm or so. You might hit a water passage or you might not. get a junk block and bore it out and see what happens.

Everything else- READ! Theres alot of info in the stickies and alot of info in this thread and the links it contains.

~Alex

 

I've always wondered where the 250HP figure came from. Maybe I missed it..?

 

no.1 NO
no.2Nothing
no.3Good Luck
no.45speed VG or VE trans but 6speed will require you to modify the bellhousing or swap the VQ motor so good luck on that one.
no.5Like Brian said, it depends what trans will use.

 

Im pretty sure they dyno'd the pathfinder with it.

~Alex

 

No updates on the engine swap yet????

 

if u build it,it will fly.

I don't know if this link was added earlier... But it's a good tid bit.


EDIT: I used the words 'tid bit' wtf is wrong with me these days....

 

O/T question: goon how far are you from Roswell?
