wel some guy I know is selling me the the whole block complete with heads for $200 will the bottom end of the engine fit into the VQ30? I read a thread a long time ago about doing this but never heard of an outcome. I need to tell this guy if I want it quick or else no more VQ35. BY the way its brand new still in the crate. Any info will greatly be appreciated.

I posted this in the 4th gen but no one knew can someone help

 

Contact Mardi Gras Max he should be the one will definate answers.

 

I definately want it if you don't take it. Just let me know. Pleease!!!!!

BTW, I'm in Houston, so I will drive down to pick it up if you don't take it.

He's selling a "brand new still in the crate" VQ35 longblock for ONLY $200? Sounds WAY way too good to be true.

BTW, you could EASILY part that out and make it worth your time. I'd give you $200 just for the crank/rods/wrist pins.

 

From what I know - yes it will fit.

3.5 block
3.0 heads/mani

 

D_Warner it is mine, haha! I will race him to El Paso first one there gets to buy it. Ya if you don't want it I will skip school and go pick it up.

Contact me before D_Warner!

 

Hey Stephen. First come first serve man. ha ha

 

A race David, come on! Ha Ha

 

dont worry warner you got dibs on the block if i do decide to buy it

 

Doh!
12345

 

Any power gains?

 

Que?

 

around 10-15 hp

 

LOL...let me ask you this, if there weren't any, what would be the point?

 

To build a hybrid VQ with some boost.

 

Have you actually seen the "brand new" engine in the crate? That engine costs a few thousand dollars brand new. Why would anyone sell it so cheaply?

I've still got a VQ35 short block in my garage- Just waiting on a VQ30 donor- Can you say VQ33.5DE-K? I'm pretty sure sliding the whole VQ35 short block under the VQ30 heads won't work.

 

Do you mean to handle MORE boost...or get more out of the boost...or...? I'm not sure what you mean by this, but I can understand there being benefits for boosting with higher displacement.

I meant as far as NA performance, though. The same engine with a higher displacement seems to me is almost always going to yield more power, even NA. Now how much, I dunno. JeffesonM seems to think 10-15 HP? (btw, do you mean crank or wheel HP?)

 

heads are the most expensive engine part, and are worth about 3k when new. whole engine retails for about 5k unless the local nissan dealer pulled the numbers out of his usual crevice.

200$ doesn't make sense. i know whole used engines from 5yo+ cars are about 500-800 so this person is either following this price guide or it's just a matter of miscommunication.

 

Please elaborate?

 

About 6 months ago, we had a '01 Pathfinder VQ35 & a '00 Maxima with both engines dis-assembled across the shop floor. Under cursory inspection, it seemed that the VQ35 had different water passages & the front cover was shaped differently to accomodate the VTC. I wish I had looked more closely and compared both head gaskets, if you have more info regarding this, please let me know.

 

Mardi is this true?

 

It dont make sense but I saw the block myself. Now I dunno were it came from but it does say VQ35 on it I was a little spectacle my self but thats what it said. Ill probably be gatting it tommorow if I get a hold of the guy




But the bottom end of the block wil fit rightistons, crank.........?

What else though

 

Heck DCM, if tis a 3.5, and you don't want it, I still want it.

 

Thats why you don't use the front cover. You make cam gears to fit the 3.5 cams that are non VTC. So you can put 3.5 liter tomei cams in the 3.0 heads and run them without VTC.

 

Nobody knows for 100% sure, but from *JUST* the FSMs, I think they will:

The only issue I *THINK* could be a problem is the valve piston clearance. I'm not sure how to figure that out from the FSM dimensions.

 

It's no more difficult then what Mardi is doing right now and probably Kev in the near future.

Mardi is using a VQ35 block, pistons, crank, ie bottom half of the VQ35 and bolting it to the top end of his VQ30. Same deal, except you RE-use the crank, rods, from the VQ30.

_So how did MArdi still manage to use the vq35 block, the quote obbove is by ICeY2K_________________

 

Posted same yhing twice my bad

 

Mardi hasn't bolted the VQ35 block up to the VQ30 heads yet. He's going to have to run low CR pistons or he'll end up with 11.3:1 CR due to the head cc difference.

 

Will he have to use thicker head gasket to get the compression even lower?

 

I think i remember him talking about stacking 2 or 3 head gaskets on top of each other at the cost of 2 degrees of cam retard.

 

Head gaskets line up perfectly, water and oil are fine. I am using lower CR pistons. Piston to valve clearance is my only concern, till I button it up and do a test I wont know, but I think it will be fine.

 

The headgasket is only mm's thicker.

 

...doesn't seem to me like it'll cause too much concern.

 

I'm with Mardis. I don't think there will be clearance problems, but doing it will be the best way to find out. I eventually want to do exactly what Mardis is doing, only I want to build a n/a version of his motor.

 

 

I am also thinking about going N/A, so I can take out some of these 12 second all motor civics on street tires here in Houston, on slicks they run 11's.

Do you think I could use VQ30 heads, that would raise compression, and use thinner head gasket? Maybe even high compression pistons or will the piston be too high?

 

VQ30 head + VQ35 stock pistons would be around 11.3:1 compression IIRC.

However, SGP makes VQ35 11.5:1 pistons, so pair those with the VQ30 head.

Both of these will probably require race gas, so not a good idea for street duty.

 

Stephen,

the stock pistons would give you an 11.3:1 compression. Which wouldn't be terrible bad in itself as long as you use some good cams with good overlap. Using High Compression cams would definately be out of the question. I'd like to go 1.5mm over on the motor and run a 9.5:1 piston. End ration would be about 11:1 and the total displacement would be around 3.6 litres with the 3.0 heads. Without boring over, you go to like a 3.3 litre displacement.

 

How can my friend run 12:5:1 on 93 octane. He has a LS Vtec. He has about 235 horses and runs hondata.
