So, I'm just about done with this swap... Engine/tranny is in, wiring harness from a 02 Altima will be here Monday. I managed to find a ECU,NATS module, and key from the same car.. so I won't have to reprogram with the Consult. Wiring this up in a Spec V is pretty straight forward. The QR25DE is drive by wire, using the same harness/pedal. We are using a 2004 Max motor, and Spec V 6spd, with a VQ35 6spd bellhousing swapped on. The trans mount bolted up.. the rear QR mount fits in the VQ bracket with a little trimming. I had to redrill the holes in the VQ bracket to line up with the QR mount.. No big deal. The front mount, and side mount, I made adaptors to go between the QR mounts, and VQ brackets. I used 1/4" plate steel and spacers.. all MIG welded.. I also had to make a bracket for the Spec V passenger axle to bolt to the block. The Spec V axles are the same diameter and spline as the VQ.. but, the splines on the hubs are different.. so, I couldn't use the Maxima axle. But, it wasn't terribly hard.. just time consuming to get it lined up perfectly. The QR uses a dead-head fuel system, set at 51psi of pressure.. same as the VQ. It shares the same fuel pump as well... The QR A/C compressor bolts to the block, but you have to drill the holes in the compressor to accept 14mm bolts.. the QR uses 12mm bolts. The two bottom holes line up, as well as the top right side.. but, it's about 1/4" too high.. so, you have to drill the hole bigger and use a washer to get a good clamp on it. The stock fans ALMOST fit... However, we opted for slim fans. The Maxima radiator fits.. no fuss.. same size as the QR.

Here's a few pics..

More pics to come..

same thread in other car forum

 

so what, this dude is doing a big project and wants to share his progress with everyone here. besides, not many people go to the other vehicle forum anyhow.

keep at it Travis, we're interested to see your final product

 

Did I post it up already? I couldn't remember if I did here or not..

Sorry... If I could have used the damn search function, this might have been avoided..

How much more additional weight is added to the front suspension with that swap?
And how do you correct that?

 

From the QR25 to the VQ35 is a 47lbs weight gain.

Mike

 

47lbs for like 70hp, well worth it.

that is awesome man. good job

 

This is awesome. I love to see little projects like this! Keep up the good work.

 

dam that car must fly with that motor. i could imagine a 4th gen with that motor running high 13s N/A.. I wonder what that will run in that sentra!

 

Too bad the sentra got porkier along the way, it's now at ~2750lbs from what i recall. Imagine if it was the weight of a Civic HB with that engine

 

That's an amazing feat stuffing the VQ35DE in there. Now mod the VQ

 

So how many different people are doing this swap while all posting pictures of the SAME car in each thread? And posting conflicting information about this exact same car.

IB4MOVETOOTHERCARSFORUM

 

Interesting swap. Keep us posted when that thing is ready to roll, especially the times if you are planning on taking to the track.

 

I love seeing this the spec v in my mind was the way the 4th gen should have been .ive seen 70 + in the slalom STOCK .
Lighter start weight great handling and it seems like a full swap is easier than putting it in a 4th gen.

mods please keep this type of stuff in the forums because one its maxima related and also it may spur swap kits and better ideas with sharing ideas.

 

this kinda reminds me of what happened with the thread wit tilley and the 350z peoples...


but good luck wit this swap and dont mind the people saying trash here.

 

If you turbo the QR, you gain that weight when you bolt on a turbo manifold, turbo, FMIC, piping, etc

 

Thats just nuts, I give you lots of credit for that swap.

 

And who in here is talking trash? A simple question has been asked which was repeated by someone else in the other thread.

 

wow... for the swap man...

this doesn't look like a cheap swap...how much $$ have u invested so far?

 

Nice cat wait till i get my 93 altima running with a VQ. BTW travis if you need any parts feel free too hit me up i got VQ parts out the azz inc a few 2k2 and newer harness's.

 

Crazy J posted it in Other Cars, and it is his spec that Travis is working on from what Ive read on other boards.

 

That has already been established. Thanks

 

well move the battery to the boot and most of that 47lbs will be balanced out again.

Mike

 

i would have just got a bolt on Turbo kit for the SpecV and called it a day....
good luck with the rest of the swap!

Ant

 

very nice...I want to see some 1/4 mile slips when you're done.

 

That was my original intent as well ... but the QR has so many weaknesses its not even funny. Boosted QR's are dropping like flies because of things breaking. Altho there are some running strong .... there are a few problems u will eventually run into

 

props to you man. i cant do any more projects currently cause dont have a place to do it at.

 

thats alot of work man, are you doing that by your self???

 

I don't understand what's so confusing about this swap, SR20DEN?.. What are you confused about? It's a VQ35 swapped into a Spec V.. Nothing more, nothing less.

Thanks for the props... I figured that the Maxima guys would love to see this.. which is why I posted it here. I forgot that I had posted it already.. I am human, and I do make mistakes. If I could have used the search function, I would have been able to find my thread.. I just couldn't remember if I did or not.

I have built some sick cars.. granted, most people don't know me, or my business. I have lost the lease to my shop.. After hurricane Katrina, my landlord decided that he wanted double the money for his building.. since surviving property is worth gold right now. I have been with him for 2 1/2 years.. I guess loyalty means nothing to people these days. So, yes, I am working out of my 2 car garage.. pretty humbling.. going from a 4K square ft shop, to a 2 car garage and a spare room. But, I get my work done regardless.

A turbo QR is fun.. but, reliability in stock form is questionable. This is a more reliable setup, obviously. Believe it or not, it wouldn't cost THAT much to do if you sourced a cheap motor. The QR trans is used, with a VQ bellhousing.. 3 mount adaptors have to be made (2 engine mounts, 1 axle mount). A 2002 Altima 3.5 5spd harness, ECU, and NATS module, with matching key.. and you're done. It's not THAT hard... I consider building the destroked QR way harder than this. Anyone with any wrenching ability should be able to do this.

John's car... I'm building it... no big deal.

 

Keep up the good work. Dont mind sr20den he can be a ***** sometimes but he can also supply good info.

 

I just wanted one simple question answered, which got answered in the other thread. And I wasn't the only person who brought up the issue.

 

TurboS13Hatch , to bad im not still in the area, i would let you work some hamburger magic on the chariot !

 

I know how you come off too new peeps.

 

Hey man! Long time no speak... Where are you these days? Someone said you were going overseas or something?!

 

Very impressive job. I'm going to sticky this one for a bit. May be a gray area since it doesnt involve a maxima, but i'm sure our members would like to see more about this.....

 

F*CK this NATS crap...

After wracking my brain for 2 days, elbow-deep in wiring.. I finally thought I had it all finished up. Guess what... no fire... So, I hook up a LED to the NATS output for the security light.. and it stays lit when the key is on..

When I checked the voltage on the other pins... I noticed that my 12v constant was dead.. So, I traced it back, and just my luck... the damn fuse was blown for the 12v power supply that I decided to use. So, I guess the NATS module went on lockdown because the 12 volts constant wasn't hooked up... OR, because I didn't have the LED security lamp hooked up? At any rate, I have to get the Consult from my buddy, and see if I can clear this thing out. Any tips on NATS from someone who's messed with it? And, can Technosquare, or anyone else program the NATS out of the ECU?

Travis

 

My plan would be to tow the car to the dealer and have them program the Sentra keys to the new ECU.

Or, use the valet key insert that you would use for the remote start on a new alarm. But you probably don't have matching keys for that ECU.

Other than that, TS can clone a ECU but if they can't program a Sentra CAN ECU they probbaly can't retrieve the NATS from it anyway.

 

Good job on teh swap. Keep us posted!!!
