^^^^^Thanks man, really appreciate the help. This is another one of my swaps that i just got near to finish with. my friends rx7 with a vg30dett single turbo megasquirt set up.http://s1282.beta.photobucket.com/user/ ... sort=3&o=0 . Anyways this is a swap ive been wanting to do for a while, got a deal on a 2003 vk45de and it was history. Didnt like how the 2002-2003 intake manifold looks so i changed it out for the 2006-up style. Sorry for not having a step by step picture but as you can see i also modified the plenum with a custom set up to adapt the 1990 q45 90mm http://s1282.beta.photobucket.com/user/ ... ort=3&o=11 . Also had to modify the oil pan to sit engine lower in the engine.http://s1282.beta.photobucket.com/user/ ... sort=3&o=2, http://s1282.beta.photobucket.com/user/ ... sort=3&o=5, http://s1282.beta.photobucket.com/user/ ... sort=3&o=3. Will post more pics when possible. Should be ordering my adapter plate from bret at swap-1uz.posting.php?mode=reply&f=193&t=566213#

Yeah ill post some pictures soon. The adapter plate arrived but I'm not sure if I'm going to use a vk45de starter or a 300zx tranny starter. Oh Yeah for those who don't know the vk45de transmission/ engine bolt pattern and vh45de are 99% identical. So all those adapter plate whether it be from mazworx or swap1uz etc it will. Will also post Picture of exhaust flange when it comes this weekend.

The vk45de was first introduced in 2002 in the infiniti q45 and then the m45 which was producing 340 hp. If you need more info you can check wikipedia.

Ok, I know this is my first post but this is something that the FSM and searches have not told me yet.
Where is the crank pos sensor on these engines?

also what ECU package are you going to use? Stock, or aftermarket?

The crank position sensor is located between the engine and tranny. The trigger wheel is on the flywheel. I'm planning on using the mega squirt 3.

I'm not sure but you can always fab up something. And if you get the 2002-2003 engine the transmission ( your tranny) will bolt right up! Or if you want you can use the same adapter plate made for a vh45de. Same bolt pattern.

I have a 370z 6 speed behind my VH, I helped Brett(swap1uz.com) get the measurements and stuff for his adapter plate. Glad someone else picked one up.

Yeah but I had to modify the engine subframe. If I had use the 2002-2003 intake manifold it would have fit, but I'm using the 2006 intake which is likes an ls1 intake on steroids . Wouldn't change it for nothing though. :biggrin:

I thought the 2002-2004 made more hp than the newer VK45? I couldn't seem to find a picture of the 1st gen VK45 motor. Is the throttle body in the rear like the VK56?

Well I didn't make my mind up yet but I'm more leaning towards using the z32 starter which I already have. If your using a 350z or a 370z tranny you will need to use the vk45de starter with the 350-370z flywheel and etc to make it work. That's good that's someone else is swapping this into something. :dblthumb: I

Yes it did make more power 340 hp compared to the 325 hp the 06 and up made, but that has to do with ecu tuning. Search vk45de in a google browser and you will see the one with the throttle body coming out the side. Make sure you go into images.

Are you sure you can use the VQ flywheel? I dont think the VK starter will engage it properly.

If the VK45 uses the z32 flywheel, you should be able use the OE starter with the z32 na flywheel and either flip the gear or use the VK gear on it. This is what VH guys do, to run the Z33 trans or any trans other than z32.

I love this engine so far, tearing it down gonna replace some gaskets and a few other things just to be 100% sure its in good shape might do the jim wolf cams and springs and POSSIBLY drysump. mine is the 2002 q45 version. only other problem that i may have is the cam pick up, because I am gonna be using an AEM series 2 box and this has un-even cam tooth spacing.

Well I dont see why it would't being that the vq35de starter is bolted on the engine like the vk45de and vh45de. It would make sense that the flywheel from the 350z would best fit and match the gear or tooth. I think theres guy on here that ran into a similar problem using the vh45de starter with a z32 flywheel and I think he had to shim the flywheel to make the starter engage the flywheel. At the end of the day anything can be made to fit I guess. For me im more leaning towards the z32 starter and flywheel etc. :biggrin:

Yeah I love mines too. Mines is a 2002 model also, I just loved the way the 06 and up manifold look so much I had to get one. Its crazy that no one else have ever use this engine with that much hp for starters which I think is being choked by the luxury car computer. A few of my friends have ls1 motors in there 240sx, a 5.7 liters making 350hp while the vk45de is only 4.5 liters and making 340hp :confused: :gotme . Anyway Iam also going to do jwt cams, cp pistons to mines see how much I can get out of mines. You should start a thread so we can see your pictures and follow ups.

yah i know, I had a person tell me that "oh a sbc will make more power at a fraction of the cost" I laughed a little then broke it down too him. Ill make a thread in the future, right now the project was just tare down and clean. I wont officially start on the project till next year because of military deployment. It sucks because I really want to get cracking on it!
