I was using google to find more info on the VG33E when I ran into this thread below hybrid VG. Basically what is being said is that a VG33 could make over 250hp NA with pistons, cams, headwork + bolt ons. I personally would love to build a 200-220whp NA VG motor. The magic setup is a VG33 block stuffed with VH45DE pistons. That gives you a 3.4L VG and bumps compression from 8.9 to 9.7.

 

um, no, the pathfinder never came with a s/c motor

you can get more power then 240 out of a vg series.

hell im at 200 with simple bolt ones

 

Matt(93SE) also has a picture showing an side outline of the VE30DE vs the VG30DE. I'll try to find the picture.

Do the VH45DE pistons have the same wrist pin size as the VG30E? Do the VG30E and VG33E have the same wrist pin size?

I found on this link that the VG33E has the following:
Bore: 91.5mm (3.602")
Stroke: 83mm (3.268")
CR: 8.9:1

I found on this site that the VH45DE has the following:
Bore: 93mm
Stroke: 82.7mm
CR: 10.2:1

The VG30E has the following:
Bore: 87mm (3.43")
Stroke: 83mm (3.27")
CR: 9:1

The VE30DE has the following:
Bore: 87mm (3.43")
Stroke: 83mm (3.27")
CR: 10:1

The VG30DE has the following:
Bore: 87mm (3.43")
Stroke: 83mm (3.27")
CR: 10.5:1

The VG30DETT has the following:
Bore: 87mm (3.43")
Stroke: 83mm (3.27")
CR: 8.5:1

The Wrist pin for the VE and VG30DE/VG30DETT is the same diameter/length, the wrist pin for the VG30E is smaller. The connecting rod journal size for the VG30E/VG30DE/VG30DETT/VE30DE is the same.

If you guys would like, I can take pictures of a VE30DE crank next to a VG30DETT crank and VE30DE pistons/rods next to VG30DETT pistons/rods later today. Personally I was planning on going to put 10.5:1CR pistons from a VG30DE into my VE, and use the stock VE rods.

 

Isnt the VG33E block the same size as the VG30E with just a larger bore to obtain and extra .3 displacment? If this is the case, boring the block out another 1.5mm is a little risky. Does the VG33E share the same oil pump as the VG30E?

 

sooo.. what is this tread telling me? besides that im stupid
someplz explain this to me... i looked over it like 3 times and i think ppl are confusing enigne names

 

where are you confused?

Yes, it is correct, the bore and stroke is the same for VE30DE, VG30E, VG30DE, VG30DETT

 

from my understanding on the truck end of it all it is the same block, the heads interchange with the vg30e. but the cc's of the head are bigger and drop the c/r

you can get 3.3 liters from a bore and stroke, its just not all from a bore

 

I am totaly aware that stroke can increase displacement but the VG33E and VG30E share the same stroke, 83MM.

 

Do you think that the VG33E would be able to fit inside of a maxima?

 

it has already been done, some "minor" modifications had to be done, but it has been done before

 

if you have the vg30e right now the vg33e and vg30et are probably the easiest. the ve30de would require a lot of other swapping (i.e. lots of electrical stuff). the vg30de(tt) won't fit.

 

I'm currently in the middle of a similar project, though I used a VG30E block from a 90 Max. Bored it to 3.3 (91mm bore) and ported the heads and intake, got the cams custom ground, and got a set of headers. We'll see how it goes here soon, just put the heads on this morning.

 

why not just VE rods, VG30DE wristpins and pistons? that'd give 10.5:1CR, up from 8.9, and alot easier/cheaper than all the VG33/VH45 frankensteining.

 

already done

 

I'm waiting for the parts to come

 

The VG33E fits, but it is nowhere near simple to do. This has really sparked my interest, though...so when the money starts to flow for me I'm going to give this a whirl.

 

did you ever get all those problems worked out?? hows it running?

 

The engine runs beautifully...the noise problems I was having were because of rusted/bad wheel bearings up front. I've got some maintenance to do with it when I get back from school, but once that's done I think the car will be in good shape.
The biggest problem now is traction...at any point in first or at the top of second, I lose traction if I nail full throttle. To combat this, I think I'll have to go with a new suspension...leaning toward eiback/tokico right now.
Once low end traction is better, I can work on breathing improvements, like y-pipe and full exhaust to help out the top end and really see what the 3.3 is capable of.

 

warning stupid question... Can this be done with a VE if you bored it out?

 

boring a ve could only get you to maybe 3.1. you have to change the stroke to get alot more

There are the facts gentleman.

 

So you're telling us that a stock VG block with a bore of 87mm has enough meat in it to go to 91mm, a 4mm increase? That's excessive, the most they would ever go on old L28 siamesed blocks was 3mm.

Also, a 91mm bore on a 83mm stroke does not equal 3.3 liters. It's still a little short at 3239 cc. That's why Nissan uses a 91.5mm bore on the VG33 to equal 3275 cc.

And since the VG33 already comes with the 91.5mm bore the guy was able to punch it out to 93mm which allowed him to use the 93mm VH45DE pistons. But what wasn't mentioned is that the VQ30DE, VH41DE and the VK45DE all use a 93mm bore. However the wrist pin height between them is different.

 

so let me get this straight.
vg30e - maxima (obviously) / z31 na
vg30det - z31
vg30dett - z32
vg30de - j30 / z32 na
vg33e - pathfinder
vh45de - q45

the xterra has the vg33e correct? what about the supercharger xterra?
where did the vh41de and vk45de come from?

 

VH45DE '91-'96 Q45
VH41DE '97-'01 Q45
VK45DE '02+ Q45

 

mmhmmm...i get it
thanx

what about the exterra? anyone know which engine it uses for the supercharged version?

 

There is no such thing as an Exterra.

However the Xterra supercharged has the VG33ER

 

thanx once again...
exterra <> xterra same difference

 

 

what makes it difficult to put the vg33 in a gxe?

 

What are your mods?

 

i'm interested in doing a VG30E to VG33E swap.. what kind of work needs to be done? cutting? cutting where? around engine mounts? the tranny fits the same? electricals?

with the VG33E having just larger bore but same stroke as the VG30E it should be around the same height and should fit quite well into a stock maxima engine bay. what are the difficulties?

 

Probably engine mounts. TB setup for the intake, exhaust issues from it's manifold to wherever else. THe usual crap.

 

I read somewhere that you need to swap out the oil filter mount... Other than swapping intake plumbing & engine mounts, swap should be simple enough.

 

can you tell me what the best thing to do to a ve30de ? in a maxima se? i would really appreciate some help

 

WTF? I thought this thread was in the stickies.

Everyone will tell you that the easiest and best thing to do is to get a wsp y-pipe. up to a 20hp gain!

 

yea, i think this thread belongs in the stickies

 

We put the link in the 3rd Gen FAQs & PERFORMANCE MODIFICATIONS sticky. It was not necessary to have so many stickies up, just refer to them next time

 

y-pipe
High flow cat or test pipe or cutout
catback
CAI or short ram intake
engine is already 10:1 compression, so you could raise it to 10.5:1 with VG30DE pistons
Supercharge or turbocharge
nitrous
timing advance (NA)
UDP
Flywheel (5-spd)
engine grounding


blah blah blah... what do you want it to do?

Brian

 

You forgot UDP

 

aka blah blah blah...
