nissan VG30e In a Fiero(Is this doable?)

Forever-Fiero · Post by **Forever-Fiero** » Fri Jan 12, 2007 6:46 pm

Just a thought. I like the VG30's power and Im a big fan of Nissan, and thay make a lot more aftermarket parts for it then the GM 3.4 DOHC! On top of that I think the Nissan FWD trans is more durable and can holed the power better. I don't know about the weiring but im guessing its about as hard as any. Well tell me if this is just a pipe dream or if im on to something good. :thumbleft:

pipe dream.

VG30E or VG30DET or VG30DETT

Doable? Yes.

Ever going to get done? No.

At this point in time, I'd go with the VQ35DE + 6 speed trans from Altima or Maxima.

Put the Pontaic Arrowhead on those boobs.

For all the work and breakthrough engineering involved, the LQ1 is a shit load easier, and the lack of aftermarket makes up for it. In Custom cams don't cost much more than pre-fabed set for the Nissan motors would, and either way headers would require a custom set to use in the fiero, light flywheels can be had, a 96 intake is plenty good. Forged pistons exist, port and polish can be had anywhere, so in all reality, what would make a one of these motors so far superior to own, other than coming ready for boost, either way mounting a turbo in the fiero would require custom fab work.

I honestly don't think the advantage of aftermarket is worth it seeing as most of whats available for it would have limited applicability in the fiero.

And besides, whenever a dumb thread like this is started, the person who started it talks about his knowledge, skills and ambition (which I always seem to question as do others), takes everyones bashing, and say they're gonna do it anyways, a month later you see his/her car in the mall, and the guy disappears from the forum because he finds a civic or something. This is a pipe dream just like any other foreign motor swap, MR2, Rotary, B18, what have you. oddest motor I've seen in a fiero was the 4g63. no bash against you but for seriousness, can you do it? :scratch:

Doing its not the problem. Gathering good info is. And no i'm not a punk ricer with no skill under a car. I'm in no hurry to do it ether! Oh And I don't live anywhere near a MALL. :bootyshake:

(Will) what year max. came with the 6speed? The VQ30 is as thick up here as the VG30 so whats the benefit of the VQ?

Ive just completed my LQ1 swap in my notchback and want to go a different way with the fastback, Just undecided what to do.

My biggest reason for the VG30 idea is I have a Villager with one in it with 218.000mi on it and it will still role smoke of the tiers(235/75/r16) and pull that heavy ass van to 100 in no time. I know its cheese but for a van it's got some balls

I was referring to the mall as the area where ads are posted on the forum, but its all good. And since you know the workings of a swap, its all good, but i think the wiring is going to be a world of hurt. It's doable what isn't with enough money, but I think when it comes down to it, cost for cost, work for work the 3.4 is better because its got more displacement. But don't listen to me, listen to what you want to do, I would hate to see something start, then end up parted out on eBay because it turns out to be to challenging. finding a Programmer that will do nissan code to comply with GM electronics is potentially a hurdle, but with enough cash you can have anything you want.

Explaining the difference between those is like explaining the differences between an LS1 and an LT1. The LS1 is just newer and better. You can make a lot of power with a traditional Chevy, but the engineering in an LS1 is 30-40 years more advanced.

AFAIK, there was never a VQ30 built. They're all VQ35's. The advantages are that it's a newer better engine. It makes as much power (280-300) N/A as the VG did turbo. The VQ is lighter because it's all aluminum and the VG has an iron block. The VQ has better heads, better cams, better variable valve timing, better everything. It's a newer, better engine.

And it has a 6 speed transaxle.

Why waste time trying to make nissan electrnics compatible with GM? Why not just take the ECM, etc. out of the vehicle the nissan engine is coming from?

Prolly have to build a whole new wiring harness from scratch though.

I say just use a GM engine it would be alot easier. Why not build a twin turbo 350? But if you really want to do this you might want to run mega squirt or another stand alone to simplify the swap. GOOD LUCK! :thumbleft:

6 speeds came in the SE Maxima in 2002+

2002-2003 maxs we rated at 240 crank, when dynoed they would put 205-210 down at the wheels

Stock 2002 SE 6 speed:

(Why waste time trying to make nissan electronics compatible with GM? Why not just take the ECM, etc. out of the vehicle the nissan engine is coming from?)

Good point. I had planed on going with a stand alone if I go threw with this. Like I said this is a long term goal so the Money wont be a problem.

I agree with Will and will go with the VQ for the engine and 6speed if I can fined one. (Are thay electronic?)

I would like to turbo this setup and look for 375-400 W.H.P will the 6speed holed that?

FieroWannaBe · Post by **FieroWannaBe** » Sun Jan 14, 2007 3:18 pm

I didnt really mean a gm ecm working with the nissan motor but the nissan ecm working with the gm gauges and cabin harness. I guess using the nissan guages would fix that though.

The Dark Side of Will · Sun Jan 14, 2007 4:25 pm

My understanding was that it's not hard, with bolt on parts, to boost the FWD Altima/Maxima engines to the same power output as the RWD engines in the G35 and 350Z.

A couple of companies make turbo kits for VQ powered cars. I think there is at least one available for the FWD cars. This should be adaptible to the Fiero.

Nissan electronics are the way to go on the stock engine/powertrain.

GM senders can be used to drive the Fiero gauges. The only potential issue I see is the speedometer, but Dakota digital has products that should allow that to be adapted.

You're still looking (almost certainly) at custom axles, more plumbing difficulty than with a GM powertrain (adapting fuel line fittings, etc), custom powertrain mount brackets and a good many other difficulties associated with doing a certain swap for the first time.

Engine mounts aren't THAT hard to build, and if you have a decent welder, making new hard-points on the cradle shouldn't pose much of a show-stopper either.

For me, I see the adapting of the shifting mechanisms to be the biggest problem.

Not only would the shift assembly need to be different, the cables need to be longer, and the whole works would have to be inverted 'cos the tranny's in the back.

My family's owned 2 vans with that motor. It's a good little motor, sounds great, and seems to make a nice smooth power curve. And yes, hauls that heavy-ass van around town in quite a respectable manner.

(Mach10) When you say the trans is in the back you mean the front?? Because the Fiero's is in the back. And if it was in the front wouldn't that make it easier??

(Will) VQ30 was in pre. 2001/2002 maxe's.

The crank will holed 400+ and the block is good 500+ the problem is the pistons, they're to brittle to holed boost or high RPM. I had planned to go with JE's with EAGLE rods.

I think I've talked my salf in to this swap! this will be Fun to say the least! I wont write a Post on it(do to the length of the swap time) en-tel done completely :thumbleft:

If you're going to put the engine in the fiero with the tranny in front of the engine , where are you going to put the engine itself? There's not much space behind the rear axles.

p8ntman442 · Post by **p8ntman442** » Thu Jan 18, 2007 7:45 pm

better question, if your going to a different manufacturer, why go with this motor, are there better motors that would require the same amount of work and be better in the long run?

Remember that the shift cables in a nissan go to the transmission from behind it because the engine is in front of the shifters. In the Fiero, the cables come in from the front (because the engine is behind the shifter).

Pulling the shift cable on a front transmission becomes a push movement on a rear. This is why you need a rodney shift bracket adaptor to use other GM 282s in Fieros.

Capiche?

Actually, that's not why you need the Rodney Dickman pars. Rodney's parts are required because the shift shaft on the FWD transmissions is shorter than the Fieros and the linkage has to be modified accordingly.

Think about this... if you pull back on a shifter in a FWD Getrag car, the cable pushes, comes up to the shift shaft from behind and below and turns it clockwise.
In a Fiero, when you pull the shifter back, the cable pulls, comes at the shift shaft from in front and above and turns it... clockwise. I don't think there will be logic problems with adapting the shift mechanism... just mechanical problems.
