Bought 04 Maxima J31 from elderly couple

Once serviced and roadworthied I discovered Frankenstein engine under the bonnet

it has Infiniti Skyline Gt500 engine

but with a difference it has Aus maxima dual plane inlet manifold

Spoke with Ian Gibson USA Nissan Master tech- He has confirmed as engine number ends in A

No Australian Maxima engines ever did

Ian suggests approx 225 to 235 kw at flywheel

Car is quick as in from 4.9 to 5 .7 0 to 100 kph- best power under10 degrees Celsius 

Has anyone else ever heard of or discovered such a rare thing.

seems unlikely, would need bit $$ spent, the higher powered VQ35 fitted to the V36 skyline were dual intake and were externally very different looking to the standard DE engine, it would require a complete ECU and wiring replacement as well as trying to get it talking to the factory auto TCU.

They were also a VQ35HR, not DE.

There also was no 'infiniti Skyline GT500'

There was a Skyline GT-R GT500 race model but it had a RB engine, not a VQ.

Even the V36 skyline with this engine won't do 4.9 sec 0-100 with it's 5sp auto, so I can't see a J31 managing this with it's 4sp slush box.

As above.. pictures please!

Hi All,

Updating mystery VQ35 de engine in J31 Maxima

So there are doubters

Well believe these facts as they actually happened

Driving to Sydney from Melbourne

Dragged Bf xr6 turbo with upgraded exhaust at a least most likely a tune etc

Maxima held and pulled past at around 190 Kph

Only slowly but did it stopped drag at 215 kph both of us backing off

Way back from Sydney ran VF SSV redline Ute big exhaust and cold air intake 

Manual both dead even from 115kph till 180 then Max pulled like freight train

through to 230kph

SSV guy shattered

Max can beat 2017 VW GTi 7.5 performance edition to 100 kph by 3 lengths 

known 6 second car

My mate Scott owns it and we have had over 50 runs

 Max has 4 gears 3rd goes from 135 to 215 kph so monster pull from 170kph onwards 

Timed Max near Camperdown 100 to 200kph

Constant 10-11 seconds with big pull 170 kph onwards 

Two times in succession reeled in FG XR8 Sprint 100 kph to 230 kph Blown Miami V8 has 650  on over boost 

Lost 10 car lengths when hit gas at 100 kph but slowly reeled him back at 170 gaining rapidly

on phone going I’m coming bro then at 200 up it’s ass saying get the f**k out of the way

Past it at 215 strongly his blower howling

And yes the sprint had the limiter removed for those who know

I can’t explain it guys 

I work at a Nissan dealer

They all love it

One night only 2 car lengths behind a Mits Evo at 200 and holding

Known 4.5 second car it also has mods

Its fun

Scary as shit as chassis brakes and suspension can’t keep up with it all

Motor is what came with car

I think it has been a test mule for Nissan R & D

 Undisclosed  but exists

Still runs a sub Six 0 to 100 kph after Thousands of redline thrashings 

One thing I do have to do is reset ecu very often

It richens mixture temporarily to protect engine as it retunes it’s own air fuel based off driving 

After 3 or 4 days of 16 lph thrashings she settles to 12.5 lph 

loses  power though 

A good half second to full second 0 to 100

So there you go

Frankenstein engine punching well well above it’s weight 

Honestly

It's not a fact when you haven't proven anything. You're a complete stranger on the internet and you expect us to take your word for it.

If you came here to beat your chest before the gullible, you're in for a rude shock. Photos, videos, timeslips, a visit to the dealership where you work, you name it, we expect to see it, not your empty words.

Ok to all who have commented

No timeslips no photos no proof

Accepted not here trying to prove anything It exists

Same as Hokden Australia placed L34 spec heads on 1974 Hj PRE pollution 308 motors but only  in Statesman and Monaro

Those motors had 275 hp plus same as 350 Chevy and kept up easily with them

Point being one of a few Aus J31 maximas with factory tinkering or as Nissan techs say maybe a Frankenstein 

Infiniti G35 bottom end with Aus top end

VQ35 engine number ending in A

No disrespect but The VQ35 de is underrated as it’s expensive to unlock the power 

Nissan Japan created my Maxima 

maybe by mistake or possibly intent

It is a beautiful feeling watching the faces of people in modified or expensive high performance cars as my J31 pulls away from them

Current Kia Stinger

0 to 100 Maxima touching bumpers at 100

1 car length and done 3 to 5 times

Even when Maxima had burnt out O2 sensors and was drinking 21 Litres per 100 klms

Running With petrol smell flooded completely

well Stinger from Dig only 3 car lengths ahead

Gt mustangs I’m 2 to 3 car lengths ahead at 100

Heres a shocking one

Holds 17 to 18 Audi Rs 3 to about 60 koh

then Rs3 just explodes learnt my lesson on that one

Bur same drag done Twice with Rs3 driver then sling comes 17 Mustang GT 

We both smashed him from a dig

He wouldn’t run us again and Rs3 driver was laughing at next set of lights

Ive had loads of guys I’ve beaten motion to me to open my window after running them

Saying is it boosted Nitrous etc

Evo Guy I worked with was shocked saying it doesn’t make sense not many guys keep up or get near him 

We had done 3 dig pulls in a side street to 90 kph

He beat me but only by 1to 2 car lengths each time

We then went out onto main road and ran from 80 to 150 same result 2 car lengths and closing

Fg xr6 turbos non modded 

Hangs with them and always a car length in front from a dig to 100

They are the most shocked but intrigued by the Maxima and often pull over to talk and see under my bonnet

Nissan got it right whatever they did

I have stock exhaust No tuning or chip

I have removed the front air intake over radiator to help breathing

Big difference and throaty air intake sound 

Only slight difference is the engine rumbles a little at idle like slightly larger cam profiles 

Also hates anything less than 98 Ron fuel like seriously hates it so suspecting slightly higher compression than stock

If the motor had been rebuilt who knows 

older guy who owned it may have had it rebuilt after starving it of oil due to their consumption issues

It did have three broken engine mounts and two cvs were shot when I bought it with only 100,000 klms on the clock 

Maybe the old guy who owned it had some fun too

In ending It’s genuine and honest 

All that I’ve written

Cant explain it 

I love driving it and have so much fun like the ultimate sleeper Grandpa car 

I wish everyone all the best and respect everyone’s opinions

Sick story bro

amazing formatting.  Sounds like your world is amazing.  
 

PUT IT DOWN A DRAG STRIP AND POST SLIP 

 

stories don’t count for shit. 
Even if it was what you claimed it wouldn’t be that quick

Thanks bro

As we all know that was in D for drive

Holding mobile and trying not to stack

When Vehicle stability is switched off and I stalk it up and shift manually gets to 100 a little quicker

Wished I had have held it to 200 plus so people could see the third gear pull from 170 to 215

I hope it helps people believe it exists

    • What does it look like with highway driving? And yes, I had a similar thought as Duncan. It looks quite similar in my Stagea and I have made myself accept it as normal. Might have to look into it some day  
    • While I was waiting for the new parts to come in for the charge pipe and radiator I decided to do some turbo modification. The drive pressure (exhaust backpressure) was a lot higher that I thought it should be. For 32lbs of boost drive was 55lbs. The turbine housing is a 1.10AR and my turbo builder has suggested to go to a 1.25AR. To test if a larger AR would do anything to reduce drive pressure AND not spend any money I decided to hog out the divider in my current housing. I removed it from the inlet and the whole way through the housing.  After reassembly and testing it doesn't look like this modification did anything for reducing drive pressure or requiring more fuel (making more power). Oh well, it was worth a shot. We'll get some data at the track if it makes it past the 60ft. I also machined a $7 shift knob off Amazon to fit my Stillway shifter since I didn't like the Stillway shift knob. Next on the list was the radiator replacement and fabrication of a new intercooler tube that had no silicon coupler. No pictures of this - I was short on time each night after work to get this done and didn't stop to take pictures.  Next was to get the clutch disks out and replaced. Previously when installing the dogbox I had ordered a set of the same sintered iron disks I had been running because I switched to the 26-spline input shaft. I thought it was odd that they didn't have any markings or brand name on them like all my old disks had but installed them anyway. At the track I could not get the clutch to lock up using my normal strategies. After two track nights I reached out to the clutch manufacturer and ask their thoughts. They said they had to switch the material out because they were having trouble getting the original material and that this new material would not take to being slipped very well.  So out with the first set of 26-spline disks and in with the correct material 26-spline disks. While I had the trans out I added an inspection/service hole. I've wanted one of these for a while. Now I can have a look at things and change the front cover shimming when needed (clutch wear). I hustled and got the clutch change done in a few hours on a Saturday. Hopped in the car and drove home. On the way home I did a 1-3 pull. When shifting from 2nd to 3rd the core plug in the back of the cylinder head popped out and dumped all the coolant. Thankfully I was only 30 seconds from home and coasted it there. Datalog showed nothing unusual and 2.5psi of coolant pressure. That plug has been in there since 1992 but I guess it worked its way out. Pulled the trans AGAIN and replaced the plug, JB welded it in, and made a brace. Also deleted the head drain I had added in during the bearing issue fiasco.  I am currently changing my boost control plumbing to make it cleaner. After that is done I'll make another attempt at getting past the 60.
    • Are you 100% sure this isn't tune related?
    • 140-150 across the board. At this point hoping the grounding harness fixes it. My grounds are all tied to the chassis and none to the battery. For SR and KA that’s never been a problem for me but had a few other guys here and Reddit who told me RB really like a very solid ground setup tied to the battery so going to try that next, I’m stumped if that doesn’t do it. Never had a car have spark and fuel and not fire off before. Only thing I can think is the spark is intermittent/weak because of grounds nothing else really makes sense at this point 
    • I am having close to the same issue. Can you help me with what wire you grounded to get your pump to trigger?
