Im hate to be asking but im wondering. I have a couple of 3.0 blocks laying around and was wonding if it was possible to bore them out to take some forged 3.5 pistons. Im asking so I dont hae to buy a another motor and do a build on top of that!

 

I know FOR A FACT the 3.0 can be bored out to 3.4....not sure if there is enough clearance in the cylinder walls to make it to 3.5.

But I know someone whos been killing it for years with a SC 3.4

 

and who might that be>?

 

I can't say, for privacy reasons.

But he's had a BUILT bored 3.0 for years....

Looks like a measily old 3.0 from the outside. He runs a 12 flat.

 

Seems like "New york" is synonymous with "Secrecy" these days. Anyway, I can almost guarantee you that whoever bored it out to 3.4 got his block sleeved. The stock block CANNOT accept pistons that large, period. Not because of space constraints, but because the stock iron cyliner liners are so thin.


To the original poster, I personally wouldn't overbore the stock cylinder liners any more than .03" because they're so thin. You'd need to increase them .098" to be able to fit stock bore sized VQ35 pistons in there. More than triple the generally accepted limit. If you do it, you do it at your own risk.

 

Yea Nismology we "are". The reason is I've had things stolen days after posting it on the forums. Some people live in "safer" areas than others, if you haven't realized that these forums are a mode of gathering information for car thieves...you are sorely mistaken. As I mentioned to you you about a month back when I was pm'ing you about my setup, we don't like to list out everything we have on a public forum for obvious reasons. But like I said in the other thread, I'm more than happy to talk on AIM or via PM.

I don't understand why no one can understand this.

 

In that context it's understandable. It's just frustrating to hear of these sick setups and not know any more. But I understand the "safety" issue.

 

tell cmax i said hi

 

Thanks for understanding man...it's pretty frustrating. If you want, hit me up on AIM- Cardrok

Like I said, I don't have a problem sharing all the info on my build, and some of my friends', just not for all the world to see.

 

There was a reason I kept it private. You are now officially the coolest person on this board that you know him.

Mods, can you edit his post. Thanks.

 

too late, the cmax word is out

 

Have you nothing better to do than make useless posts in the threads I post in?

 

Next OT post wins the poster a vacation. Any takers?

 

Thanks Nismo.


Back to the topic. It can be done. Apparently alot of FI guys do it, due to the 3.0 having a little better design for boost. Hell the guy I know has had it for years, with spray.

 

ok well i got some think eles in mind! the pathy 3.5 from a 01. Im wonder if I cut a whole in the maxima timing cover and fab a plate over that area but im not sure about the motor mount. Im really wanting the 3.5 for more power and torque. But I dont want to have to go throught the timing componts swap so im now thinking on putting the 01 pathy motor in complete if it will work.(with pathy manifold)

 

So you'd rather custom retrofit a PF motor than swap over timing components on a FWD VQ35 that drops right in relatively easy on account of labor?

 

Well thats if after putting on the maxima timing cover that solve the ps,alt and that the all the mounts will bolt up!

 

I don't think you understood what I meant. If you want to be a pathfinder (pun intended) then go right ahead. More power to ya. But you shouldn't be under any illusions that it would somehow be less work than just swapping over timing equipment to a FWD 3.5.

 

yeah for some reason timing componets scare the **** out of me!
I did do a full tear down on my vg and did not worry about it other than the timing belt if it was tight or too tight. But after looking in the vq it just scares me to try!

 

would using the maxima timing cover fix the ps and alt problems?
Also does anyone know about the mount wether the pf 3.5 will acept the fwd mounts?

 

I was the same way as you man, just do it. I knew I could put together a 3.5 ready motor, just not the timing. After seeing it done, and watching...it's cake. Cake compared to installing a pathy engine and modding the cover etc ...

 

well fabricating is fun to me! I make all my own stuff that dont require math like a intake manifold or something! but im just wondering what I may would have to do to get it in!

 

Did I miss something? Is there a pro to using a pathfinder over any of the easier swaps?

 

not having to swap timing componets lots of torque and good manifold not sure if its better than a fwd mani though i have no idea

PF block and timing covers not found.

 

Thought it was a good read since they're asking about it, and this will ultimately be a boosted ap.


Also, better than talking about different type of pastries and with such a lame thread title, well, I thought it could use a little bit more of a technical mood.

 

error 404: still no timing cover

 

404 ERROR, Care Not Found.

 

oh thanks man

 

Honestly I'd just do the timing stuff, don't let it intimidate you. If you follow the FSM and take your time it's easy, plus all the links/sprockets are marked for you. Once you tear it apart and have a good look at it beforehand you'll see. Get some adapters made up or ordered beforehand and the actual work is cake. And if you do run into trouble there's lots of people here who've done it and can help.

 

Does anyone think the pathy intake manifold will be better for boost due to the true duel runners?
