07 altima engine
Any reason why a 2007 altima engine would not work for a regular VQ35 swap? Will the 95-01 timing chain covers still bolt to the block?
The ECU reflash is 7500 for these cars (7000 stock) and they changed the rings, rod bolts and valve springs I assume. The intake too. I still have my VQ35 nismo cams (10.7 mm lift) drilled at full retard. Any reason to think I couldnt just install these cams in a stock 07 Altima engine with the 95 timing chain assembly? Will the valve springs handle the lift (10 to 10.7 mm)? Hopefully they havent changed the holes in the block for the rear timing cover.
Any other issues I should be aware of? The new (black plastic) intake is different, does it have an EGR like the 04s? Will the maxima VQ35 headers bolt onto the heads (i.e have they enlarged the ports for the headers in the heads?).
I am not planning on doing this immediately but I'm buying back my old 95 from my brother. The 07 altima engine seems like a good idea vs the 02-06 - no oil burners, new rod bolts, new valve springs, new intake. I want to tune the 3.0 first, but I might look into a 3.5 sometime this summer.
Thoughts?

Thanks doublea.
At the very worse I could just throw the cams into the 3.0L. It already has an (untuned) 00 VI on it, and still has the Cattman exhaust system (minus headers) from when I ran 13.68. Ive got a stock 2002 VQ35 oil pump laying around. It wouldnt cost anything. I could double shim the stock valve springs (whatever the hell that means) and go to 7500. Id throw on the new OBX equal length headers (350$) while Im at it and maybe change that U-bend.
I bought the 4.47 Axxess gear & pinion again. Its from a 4WD RS5F50V trans. Same as the max 5-speed but 4WD. The gear & pinion fits but has 10 holes in it (open trans is 10 holes, VLSD is 14 holes). My new trans only has 70k on it and the VLSD ACTUALLY WORKS! So Im going to MIG plug weld the 10 holes and drill 14 ones so it fits on the VLSD. Everything other than the holes is identical. Teeth count is 76/17.
I picked up the 4.471 gear & pinion yesterday with a 0.74 Altima fifth gear (stock is 0.795) so the 5-speed RPM only goes up from 3000 to 3250 at 75 mph. Stock is 3.82 so 3.82 to 4.47 is a 17% difference. Fun times ahead.
Did I mention the frame is now a 2x3? Its better than SFCs. Feels like it has a cage in it. Floaty stock suspension still. The Rad support is changing into a 2x3 too. And im welding another 2x3 between the rear shock towers, the suspension is rusting/pushing into the trunk.

JClaw, welcome back! 
AFAIK doing the swap as you and me did with the 3.0 timing covers, would not work on the VQ35HR motor. This was determined when LA02Max (something like that) attempted to swap that plastic dual-stage VI IM into his 02 3.5, to find that the new LIM mounting bolts were spread out more than the original LIM, implying that the heads sit higher up (I dont recall if they have the same part# as 02-06 3.5s or not), or that the block deck height is taller.
So from what I see, the only way to make that motor work on a 4th gen would be to do a FULL swap with wiring harness and all.
Someone correct me if I misinterpreted the info. I am after all recalling it off the top of my head.

no pics sorry but its basically a 2x3 that runs straight from behind the front wheels, all the way to under the rear seats, then he cut another 1.5 foot long 2x3 piece that goes sideways and is welded into a 1/4 inch thick plate that is welded directly into the rear suspension mounting point. Its better than SFCs. He removed the mushy stuff under the carpetting so the extra weight (~25 pounds) is pretty much reduced to nill.
The frame protudes into the car (1.5 inch under the floor, 1.5 inch over the floor) with slightly thicker metal plates all around it since they were rusted. He trimmed down the 2x3 to a 2x2 in the front where you put your feet. Believe me when I say that this **** is STRONG. It feels like a cube on wheels on a highway offramp. ONE PIECE.
Its got a 00vi (untuned), regular winter tires, homemade y-pipe with cattman cat & catback and a VLSD. NO Wheelspin at all. I suspect the combinasion of the working VLSD and frame helps.

I wasnt correcting you I was asking.. shoot I didnt even know the se r's had hr's in them
Im also intrested in the hr short block. I hear you dont have to slleve them to make over 600whp on a z33.

Same deck height, different part number. If you want to use the new IM setup you will have to use the new heads since the stud placement for the LIM is different.
Edit: They will bolt on to an old DE block.

Only the 07-08 Z33 has the HR. And it's been discovered over time that sleeves aren't necessary in a DE to make > 600WHP reliably.

I think I'm going to go with a regular DE. The only 07 Altima engine around here is 2500. Not worth it with all the 1000$ DEs. On the last engine I got lucky and paid 600. First one I paid 1200 way back in December 2004.
I know there are two version of the 2001 Clutch. The one before Nov 2000 and the AE one that is dated production after Nov 2000. I know the first one fit, but does the AE clutch fit?
I plan on beating on it at the track, but street tires ONLY this time, no slicks. And I believe the 4.47 final drive ratio will relieve a good portion of the stress on the drivetrain, since it is 17% more agressive, so I just might pull the trigger on a 2001 AE clutch, IF it does indeed fit my 95 flywheel and trans.

Is there a reason why you couldn't import an engine from a yard in the US? UPS and FED ship ground to canada. It'd probably save you money.

They all fit. I had an 01 AE clutch, held great untill it got soaked with gear oil when the input shaft bearing went.
I cant remember, but the 07 Altimas have CVTC on both intake/exhaust correct? Combined with a better flowing IM and potentially better flowing heads, this would be where most of the gain over a 1st gen vq35 be?
What would stop one from doing VQ35 block, 07 Altima heads, and 4th gen timing equipment? Would that work with the heads or would that cause interference issues with the altima heads being taller?
