I have been reading threw the forums awhile now trying to find an answer but couldn't find a clear one.anyway i have a 03 maxima that i just bought and it has 2 spun rod bearings.i am wanting to replace the bottom end and my question is will any 02-08 vq35de engine blocks work(fwd block of course)?i thought about getting a newer block for the lower mileage and from what Ive read they don't have as much oil leak problems.i didn't know if i could just swap my top end over to a newer block or not so please any help or info is much appreciated,thank you.

Yup. Except for the 07+ altima block, it might be a little different

what about the 09+ block,are those usable also with 03 top end?i know i could use the whole 09+ engines with slight modification and have more power but id like to just use my top from my 03.

I'm an engine maschinst an you are wasting your time ad money buying another block. Unless it's cracked but u did not mention that. Take the whole bottom end out and take it to a local machine shop. Tell them to grind your crank .010 or .020 whatever it clears. And then just get oversized bearings. And if you can still see cross-hatching and feel no ware on the cylinder walls then u can get away with a hone and new rings. But you spun 2 bearings and all that metal shavings isn't staying in your bottom end. It's all over the engine. It's your heads and oil pump as well.

Machine shop work $1000+ new engine with low miles $600-$800 and anything upto a 08 will work

yeah im sure there is metal shavings threw the whole engine but i was hoping on just cleaning up the top end since it was still pumping oil up to the top and the top end was still working.the engine was still running when i started to tear it apart.but i found a couple complete good low mileage blocks for sale and that's the only reason i was gonna go that route.also it seems a good complete engine is hard to find around here where i live and what there is here they have almost 200,000 miles and they still want 1,100 dollars for it.

Your lifters are hydraulic and they are pumped full of the metal shavings. You would really need to take them out and replace them as well. I'm on the same boat you are. Spun a bearing on Monday. I'm waiting on my fried with a hoist right now so I can take it out and take it to my job. And I'm only paying for parts since I'm doing the labor. But you are saying you can't find one with less the 200k for 1100?? Think about it. For 500 bucks more you have a fresh engine with 0 miles on it. And you kno everything that has Been done on it.

04-08 motor will require new timing chain guides and tensioners if you plan on keeping the car for a long time or putting a lot of miles on it.

Perhaps you could get the vehicle history with a VIN and if it was serviced at nissan in case they were replaced already?

I never did find out last time I was wondering, can we swap the FWD block for a RWD setup?

I have a local Maxima 3.5 engine that is going super cheap, but I have no idea if I can use it. I'd likely use only the short block right.

Nope unless you change the heads

lee46582

correct me if im wrong cause im new to maxima's but from all that i have read over the past month i don't think you can use the different blocks because the motor mounts are positioned different on the block it self on the rwd vs the fwd version.

heads have to be changed.

I'd use the G35 head anyways, but will it just mount right up, no shenanigans, same compression ratio, etc, etc? And how about those engine mounts, should be the same, right? Obviously just need to switch the physical mounting bracket, but the bolt holes/pattern should be the same for them right?

cjandura

Yup and the alty/ac mounting bracket needs to be swapped over not 100% sure but my brain no good

I really don't have $600 to pitch at this but damn. If it would work that would be a stunning deal. And then sell off all the FWD Maxima components
