Can a VQ35 crank,rod,pistons,cam,and valve springs fit into a VQ30 block and heads?

Sorry for my stupedness!!!!!

NO FLAMING PLEASE

SinisterPR

I would have to say, no, perhaps one of the above may fit, but i doubt that the crank, or rods would fit, pistons definately not, nor cams would fit, i mean, its not just a bored out VQ30.

No question on this site is stupid, that's why we're all here. The G35 internals are made for RWD so because of that it cant be done unless you make your car RWD, been there done that.

CiViC KiLLeR

I did not think that they would fit but it was worth a try. Thanks

SinisterPR

It is not just that it is set up for RWD, i mean, you can use an engine that is set up for RWD in a FWD car, its just a simple matter of different engines. If it was just a bored VQ30, you could make it work, the internals have nothing to do with the layout of the drivetrain.

I have a buddy that got his that crashed his 350z and he gave me the motor. I thought that a VQ35 crank would fit in a VQ30 block and make it a stroker but I guess I was wrong. One last thing Sinister (WAR EAGLE)!!!!!!!!!!!!!!!!!!

SinisterPR

Don't take my word for it, Let someone with Extreme Technical Knowledge answer, there are folks that may have tried that, but i expect that it is not a match...War Damn Eagle.

I was under the impression, the G35 internals are identical to the 2004 maxima, 3.5 altima, 3.5 pathfinder, I35, and 350z... The only difference, is the VQ35 motor is turned side-ways for front-wheel drive applications or, it may be turned stright for rear-wheel applications....


In other words, the VQ35 motor will drop right into a 4th gen max, just turn the engine sideways and it's a WRAP!!! Just my 2cent....

CiViC KiLLeR

That is what I thought But will it bolt to the motor mounts and tran of 4th gen max

SinisterPR

Exactly what i was trying to get across, you could drop it in, and instantly whip tail. Thanks for saying what i had not yet said, Morfeus17. But, you would have to get a new tranny...and new mounts, if they are made...and a lot of other things, its not plug and play.

Sinister

Morfeus17

To answer your question.... Instead of wasting all that time and money into swapping parts from VQ35 to VQ30.... Just do an engine/transmisssion swap... Then aquire wire-harness and ecu... There are a few org members that done this... So its do-able..

Eric425

This makes me sad for us all. The 4th gen forum is dead.

Morfeus17

It will bolt up to the 4th Gen chassi, but the 5spd tranny will be an issue... Just substitue this with the 6spd gear-box and axles.... And thats it...

CiViC KiLLeR

Well How much do you think it cost altogether for the 5th gen engine and tran swap.

Morfeus17

Well to give you a rough idea...

Go to car-part.com

1. VQ35 2003 Max Engine 12k miles $850
2. VQ35 2003 Max 6speed gear box (locking diff) $1450
3. VQ35 2003 Max Axels left $65 and right $65
4. VQ35 2003 Max ECU $175

Then you will need gear shifter, console, mounts (may come with motor), harness.

Not a bad little project...


And to add it would be better to get this all from a donor 2003 5th Gen maxima... Parts are very similar..

CiViC KiLLeR

Thanks morfeus!!!!!!!!!!!!!

You are truly the one! J/K

You won't need mounts. The motor should fit on the 3.0 mounts. 3.5 have used the place racing motor mounts from a 3.0 and they say it fits fine.

Sell me the motor if you don't want it. I think the internals will fit, a shop will charge a lot of money for that work though.

CiViC KiLLeR

I have other plans for that motor but I can not talk about it.Sorry spanishrice.

if Im not mistaking some of the internals can fit. There was a thread about this a while ago. PM ICEY2k1. He is a mod on the 5th gen forums. I'm pretty sure he has research this a lot

vsamoylov

i can find all those parts in my garage. lol. my bro and i will attempt this soon.

car_boy_16

Just to clear something up, can you bolt the 5spd A32 tranny up to the VQ35de engine??

No member has done this as far as I know. Tilley has the 6spd in and is working on the engine but besides him I know of no one wha has done a complete 2k2+ swap.

Ok well you can't use a VQ35 ECU in a 4th gen unless you replace all the electronics which is just crazy. Problem being is that Maximas have used a security chip in their cars since 1999. In order for a VQ35DE engine and ECU to work you would have to swap the engine, computer, ignition locks and coded keys from the 5th gen doner car, and the NVIS transponder in the steering collum. Unless you want to cut and splice alot of wires this setup won't work.

However one member on this board has used a VQ35 block with VQ30 cylinder heads and manifolds. Also its theoretically possible to use the VQ35 crank and rods with custom pistons in a VQ30 block, making a stroker VQ33DE. (FYI using stock pistons would make a very high unstreetable compression ratio).

But what I hear from some 350Z forums is that the VQ35 block can't handle more than 9~10 PSI on stock internals. So if you intend to boost the VQ35 block you may want to look into better internals.

CiViC KiLLeR

If I do put a VQ35 crank in my VQ30 I am getting Custom rods and Pistons so it will be a turbo fed beast......My goal is 15 psi as long as it can hold 15 psi safely that is all I want.

I know that 15psi is a very high goal but I have to set it some were.

also consider that the vq35de is running a electronic throttle as compared to a cable. So just swapping in the engine will be harder than just bolt on parts and ECU

Nismo87SE

I bet some $$ that one could put a VQ35 crank in a VQ30. Actually I remember a post about that very swap about 2 years ago. Maybe you should find someone to help you search for the answer.

formz

Haha I was thinking the exact same thing. People responding to posts they know NOTHING ABOUT.

5spdFastMax

Im pretty sure you can put a 3.5 cracnk in a 3.0. I dont see why not. Ive put different cranks than the engine requires in big blocks before. get back to us with research if you find it. i heard someone say it will make a 3.3 liter. sounds sweet

vsamoylov

and also a problem you would encounter would be the guages also and if you do not have abs, that would be a problem also cause that is where the speed sensor is at on 2k2 max.

stephenlc

iTrader: (1)

No you need the 3.5 liter 6-speed

CiViC KiLLeR

You can put a VQ35 crank in a VQ30 block and it will make it a 3.3 litter but you have to get custom rod and pistons and it is alot of work.

I took the engine out of my buds crashed 350z today that was a b!tch so I got out the cuting torch and went to town cuting everything. Now the engine is on a stand and I will start taking it apart monday.

vsamoylov

what is he going to do with that engine?

CiViC KiLLeR

He gave it to me because it will not run.

car_boy_16

Why would it be 3.3L's instead of 3.5L's?? Makes little sense to me why it would be that.

formz

Because just replacing the crank wont give you all the displacement of a 3.5L.

car_boy_16

Ok...But it has the exact same bore(stroke*bore*cyls*pie=displacement)...So *Why* would it be any different?
Thanks.

BP2K2Max

what does "cyls" represent in that equation?
