kicking some ideas around, getting a 2004 3.5 with a leaking headgasket for cheap

Anybody know if the 3.5 headbolts are the same as the 3.0? Or if the 3.5 headbolts with work with 3.0 heads? i cant find the thread with the two next to each other.

and since im going to be going so deep into the engine already to fix the gasket and replace heads, how hard would it be to go the whole 9 yards and rebuild the whole thing? never done an engine rebuild yet.

im going to attempt a 00vi on a 3.5, we will see how it goes.

3.5 crank and pistons, 00vi ported maybe, either 3.5 injectors or 2k1 injectors, not sure if the 3.5 will fit in the 01 LIM, ported 3.0 heads, and 3.5 jwt s1 camshafts. all this is hypothetical since i have yet to get the heads off the 3.5 yet to see if they will fit.
aiming for high 270-80 hp

 

I've always heard give the motor what it wants. Numbers are just numbers.

 

are you going re-use head bolts? I mean you cant if you measure them and are still in spec, but either way if your going to take apart a 3.5, mineswell get new head bolts. they arent expensive. actually get HR head bolts.

 

You can reuse headbolts? I had no idea, I thought you HAD to replace them just to be safe lol.
I was already going to see if the HR valve springs would fit with the heads so the bolts would just be a +1 to the collection. might as well mention ill be using the JWT cam spacers, HR springs, cometic head gasket, and NWP might get some attention from me for the spacers but i have never been able to justify 200 for 10hp, but i probably will this time.

 

eww Cometic headgasket? are you going for an NA build? My suggestion, HR head gasket (as well as modifying cooling passage), HR head bolts, rev up oil pump, and then w/e your doing after.

 

threadlink about modifying the cooling passage? Is that the mod where you bore it out slightly but watch out for the oil passage behind it? or is that the pathfinder coolant mod? i read so many threads i get them all mixed up.

any good sources for HR stuff im at 360.84$ for bolts, gaskets and springs from courtniss. Surprisingly ImportRP doesnt have prices that can beat dealership for these parts!

yeah n/a is the objective, if i had any intentions of going turbo i would leave the heads alone since my compressions gonna be so high. i might in the next year or 2 piece together a 75 wet shot to try and break a time barrier, but thats far in my future.

 

Its none of those for cooling passages, its this, simpler than you think:

They compare the three different head gaskets, HR being the best one as well as the head bolts.


Your best source for nissan parts will be Dave B at Nissan. I dont have his number handy but I am sure someone can post it, or if you search. I got all my parts from him, as most doing builds do the same.

 

Found the pathy thread http://forums.maxima.org/all-motor/6...oling-kit.html. Im gonna check your link and post what i think. Yeah i have dave Bs number saved in my phone, just recently replaced my suspension lol

 

ah! I see its the mod that Arron did on his 3.5. Thats very interesting and i will be doing that for sure when I get the block torn down. That was one of the most informative post ive read in a awhile. It also confirmed my question about the head bolts being used for both 3.0/3.5 heads. Now i just need to figure out if the 3.5 injectors will fit with the 01 LIM or if Im going to need to get bigger injectors also.

note to self, buy new headers.
