I looked for your thread, I couldnt find it?

 

it is called :First Test Drive Finally: pics are toward the end of the thread.

 

Tilley at work today I printed up a Wiring harness diagram up from our computer Mitchell program...Do u want me to send them to you?

-Chris

 

one love man.

tilley, think you could source a good bottom end down around your area? I think getting one from the states is going to be my only optoin to get a 3.5 for under $1000.

 

I got one a few miles from me for 900 (22k) and about 10 near philly for 750-850 each

 

How is it stock with JWT cams?

 

Its nice to start with 255hp but is he gonna do anything from there cause while it was out would have been the time to do other things. I did flywheel, headers and cams while it was out(the cams were a unplanned thing cause they are so expensive, now i need another set for my car)

 

Next time don't waste your money on the JWT crap. There is a much wider selection of parts out there to use.

 

FYI 3.5 heads have so many cams out there but 3.0 has none but JWT so thats why I used them.

 

You can use the 3.5 cams in the 3.0.

 

Uh no the pins for the cams are in different locations and WILL cause major valve to piton interference. I have already looked into it, I probably could use them if I lined them up by eye but thats too risky.

 

Uh yeah did you not notice the open dowel hole on the VQ35 cams? You remove the smaller dowel and put in the larger one which is timed correctly for the VQ30 cam gears. And the exaust cam needs nothing else.

This information has been posted several months ago. Once by me and again by BlackBirdVQ.

 

Thats weird too bad I threw the cams away but I could have sworn they wouldnt work cause the lobes were at the wrong angles.

 

You threw away stock VQ35 cams? : Don't ever do that.

 

I think my 3" exhaust hurt my 1st and 2nd a little but 3rd pulls like hell. I hung with a high 12 second DSM from 20-80 and he wasnt pulling at all just got a little off the start, he thought I was S/Ced lol

 

After what I did with my girls car im thinking of going NA with my car its more fun. But i will have to go the aebs way, 4.2

 

If you're going to go NA with the AEBS you'll want to do the 4.4. You could save yourself some money by getting the 101.5mm sleeves, have it honed to 101.6mm to acomodate SB Chevy or Ford piston blanks and use the VQ35 81.4mm crank with OE rods/Nismo rod bolts, or custom rods and have a much less expensive 3960cc VQ.

 

just wait guys. i finally got my tires and will be going to the track as soon as i have some time cause school and work is killing all of my time at home and my time with my car.

and tilleys99, why didnt you get a Vi from a 2k-2k1 max? and with that high of a comperssion, going FI is just nuts. it will work but for how long though is the question.

 

Why does everyone think its gonna kill my car having a 11.5to1. Considering they make piston that are 11.5to1. It runs awesome with minimal issues. Im just trying different plugs cause it has a slight miss a low rpm.

 

With the right setup you can run as high as 14+:1 on pump gas. But most people aren't aware of this.

 

I would only be worried running 12.5to1+ on a daily driver

 

What octane does your GFs car run again Tilley?

Any detonation?

 

93 with no problems

 

Tonight the walbro goes in to help the minor leaning out on top end. Still need a payhy TB.

 

ok, first, where can you get the sleeves? second, are the wrist pins the same height? and third, will the block take the 101.6 bore?

 

I am referring to the AEBS kit. They will sleeve a block for about $2k (vs. $7800 for the complete kit). The 4.4 NA kit uses 101.5mm pistons and the 4.2 FI kit uses 100mm pistons.
No they're different. That's why I said piston blanks. It may be a little cheaper to order custom pistons that can be based off of existing forging blanks.

Not without the custom AEBS sleeves.




There is also the VQ40DE that will debut in the '05 Frontier, Xterra and Pathfinder. However that block will be much taller to support it's 92mm stroke and probably won't fit in a A32 or A33 chassis without a custom cowl hood.

 

Swaping a full 3.5 would require the 5.5 ECU/wiring. The variable cam timing is controled by the ECU. Plus he would put down more power with the 3.0 heads (extra compression).

 

The reason tilley went with the 3.0 heads was because of the higher compression? The variable timing doesn't look that complicated. There's a solenoid on the top of each valve cover. Can't you just use a rpm switch or something similar to activate it? Do a few runs on the dyno and see which rpm is best to activate it. Does it sound like it will work or I am thinking things too simple?

 

There is only one aftermarket standalone (Motec) that can control the Nissan CVTC or BMW Vanos. They don't work by simply being switched on or off.

 

+ 1


Um...C ontinuous V ariable
These engines output are continuously varied via timing of ignition and valves.

 

Can some one point me to where I can read more about the cvtc? I've only a crappy repair manual with like 2 paragraphs on vtc and nothing on cvtc.

 

Notice to all:

I am in the process of pruning extraneous posts that do not add anything of value to the subject of this thread. I will then sticky it if the other mods agree I should.

So - please stay on topic when you post. If you're engaged in some argument with somebody else, don't bother posting, I will delete it.

Thank you for your cooperation.

 

Im about to pick up my motor/ecu and harness....looking forward to this whole 3.5 swap and hope it goes smooth.

 

how much and what are u getting and who is going to do it for you?

 

Ok I am new at reading this and want to learn more about it. Your taking the short block 3.5 using 3.0 heads. Using short block your using crack rods and pistons. You get the higher compression due to the greater combustion area correct. So if I want to do this to my 00 I could. Then I could get aftermarket pistons for 3.5. Also JWT hasn't got back to me about cams but I could use those in the DE-K correct even though it says use with JWT ECU. Also Tilleys99 with it being a short block does that make the engine sit lower in your car.

 

Yes, on the 3.0 head with 3.5 block...that's what Tilley did.

No, your compression is raised because 3.0 head CC is smaller.

Yes, you could do it to any VQ30.

You only need aftermarket pistons if you intend to raise or lower the CR.

Yes, JWTs VQ30 cams will work in the DEK heads.

No, VQ35 and VQ30 are externally same.

 

short block doesnt mean its shorter. lol

You can use cams without ecu upgrade in your de-k basiaclly use the 3.5 engine block,rods,pistons,crank...........Everything else is 3.0.

 

What HP gains did you get with the 3.5 block. Have you thought of doing a port and polish on your heads.

 

I went from a 15.5 to a 13.87 (added headers, flywheel, and cams too) but 3.5 has so much more low end torque.

 

That's what I want is some low end torque.
