i am about to aquire a 88 maxima with a blown motor for about 200 bucks i was wondering if the vg33e is a direct bolt in motor and thier is a large supply of those in local junkyards anyone ever do this swap. that extra torque from a 3.3 would do wonders. and if so what donder verhicle has the best version of the vg33e. thanks

 

If you want to spend tons of money on it, go for it. Do the swap...then if you want to get more power out of it than stock, you're in for the real ride of your life...parts and upgrades will break you.

You will likely need the engine harness, ecu, downpipe and o2 sensor, stuff to adapt to the trans (flywheel, etc), afm, and more...

The reason you don't see many make the 3.3l swap is because it's just not cost-effective. I have put about $600 into modifying my 3.0l and built it up to 400hp. You'll not even buy a good 3.3l for that....and you'll be at 222hp.

I'm not trying to be rude or anything, but I think that after you realize what all will be involved, you'll change your mind.

 

what are you talking about the 3.3 motor never came with 222 hp that i know of and from what i can tell. it's just a bored out vg30 motor . the 3.3 is still only a v-6 sohc motor with 170hp stock instead of 160 hp stock. but the extra torque is were it makes it's presence known. vehicles that have that motor are, pre 2001 pathfinders, xterra, quest/villager, frontier. physically it's the same motor with more displacement i dont think nissan would change the block were the tranny bolts to it. did they? and how did you get 400hp out of that motor for only 600 bucks?

 

Hey, I'd love to know how you pulled that much power for only $600? I'd love to squeeze even 200 from my old, wheezing v30.. at 220k, and 180 psi comp all around, it's still running good, but i'd like a little more oomph..besides, i think the engine will need a little work, anyway...the front main is starting to leak a little, and the fuel system needs some work...but hell, it's 14 years old, and 220k...show me a domestic that can do that...

 

maxwagon try a lincoln towncar with the 4.6 motor they can pull the highmilage thing off also ive seen one with 550k miles on it at my job (it's a taxi too) but yeah most domestics cant pull that off very few can. ohh yeah the motor is original but of course the tranny isnt. and is there anyone who can answer my question?

 

I cold be mistaken about the hp rating. BUT, you ar mistaken about it being nothing more than a bored out 3.0l. If it were, the heads would interchange, as would the intake, exhaust, crank, and more...

I am not sure, but I do think that I have heard that the trans bolt pattern is the same...but not 100% sure.

If you just want more lower end power, why not just pull your heads and weld up the combustion chamber a bit to raise compression?

It just doesn't make much sense to spend all that money for a 3.3l and then have so many unknown troubles ahead...all for so little gain. You can get more power than that for half the money if you just build your motor a bit.
ANd you'll avoid the unknowns..

On my car...I think I left out that I actually have an 86 300zx turbo. WHen I decide I want something, I look until I find a deal. I bought MSD and nos for $310, for example).

It's the same engine (basically), as the maxima. I have MSD ignition and coil, NOS, ported and polished heads and intake, customized intake plenum,12psi boost, blow off valve, Stanza Throttle body (.290" larger diameter), 2.5" exhaust, no cat, Dynomax muffler, and more that I just can't remember...

I'm rebuilding now and planning on a Twin turbo crank and rods (takes a bit of machining)

you have a vg30t in a maxima or do you mean you have z31 turbo. im not really a fan of nitrois turbos are welcome. but have my dsm for that.(would love a z32tt) i just wanted a little more torque and the head could always be ported too. i dont know you are prolly right. i just cant believe it because if you sit those 2 engines side by side on the ground they look externally identical. but i didnt really look to hard for diffrences.

[B]I have the vg30et in a z31 300zx. Nitrous is good, if you do it right. It's like any other mod...if you do it right and the car can handle that horsepower, you're going to do fine.

Porting the heads will not give you much gain at all...you may not even feel the difference. The Japanese casting methods are really good. It's not like the old domestics that were really sorry castings...they gained a lot from porting and polishing.

One thing you may consider is swapping cams. Isky, from what I've heard, makes good ones and they have good suppport. They run about $200 with exchange, for the pair. You'd meed the same cam as the 300zx (nonturbo).

Also, raising compression will give more torque.

 

I was just wondering if it would possible to put a 300zx tt in an 87 maxima? Or if that would be too costly for the horse gain?

 

I'd imagine it can be done. One of my personal, soon to be famous quotes applies: "Where there's a wallet, there's a way."
