Well after about 3hrs of work last night i figured out a way to use 3.5 cams in a 3.0.... basically i had to make a template for the intake cam to reposition the guide pin (there is NO way around it) If you use the pin hole thats on the 3.5 intake cam it WILL be off and there arent enough teeth on the sprockets to adjust and make up for it. Exhaust cams will work no problem. Im gonna test these out but its looking good so far, now i just need to make spacers too get the cam gear where it needs too be.

 

hopefully this will make up for the low end loss that the JWT cams have

 

SO now we can use Nismo Cams? Goooood.......

 

If you dont mind drilling new holes for the guide pins. I made a template using a old cam sprocket now i can drill them out easily

 

very nice. I might be interested in something like this.

 

HKS cams have 2 pin holes for the camshaft sprocket dowell pin, works in VQ30 and VQ35. Exhaust cams are same on both engines. HKS 272 with 11mm of lift sound nasty on a VQ35.

 

Yes, Tilley you are the man I will definitely look into this.

 

 

*dyno*dyno*dyno*dyno*

 

How are the Cams coming along?

 

I think it will all work considering the 3.0 cams fit a 3.5 head with proper clearance

 

tilley, would this make up for the drop in HP your setup has vs. a full 3.5?

you only put down 220ish whp while most other 3.5s are doing 230-40 whp with similar mods. Are the heads now the limiting factor? And would using the 3.0 timing setup allow you to use the 3.5 heads without the VCT?

and try to put a vq40 into ... my max next

 

But rememer I had a stock 2k TB (55mm I think) and 2k2+ are 75mm that is a huge difference. I had a pathy TB on for a day and that was a huge driving difference.

 

Oh, I though you were running the 00VI with a pathy TB. What do you thinks the gains would be with the path TB or even a Q tb?

 

well it probably would have been a big gain. Soon coming full 3.5 minus 2k2 BS wiring.

 

cant wait to see how that turns out

 

Just about ready should be in and running by middle of next week.

 

Sounds like this is going to be another beast

 

Good stuff. Keep us posted.

 

It would be in but im waitin on a clutch disc

 

hey tilley you got a PM. get back to me asap please.

I would like to see this too. What would be the easier way. getting all other parts running off 3.0 ecu to run on 3.5 ecu or getting 3.5 VQ to run on 3.0 ecu.

 

Neither is a easy task.

 

what's your plan.

 

Ok I spent most of my day puting things together making sure everything lined up.
Here are some pics I took of the Cam Swap.
Still working on it, I'll keep yall updated. :

Rear Heads
Front Heads

 

Sweet....so the JWT idea did pan out.

 

JWT does indeed have spacers ,so i need these spacers to use 3.0m sprokets but cams are going in 3.5 head

 

write up with pics????

 

As soon as I have it actually running I'll post the write up.

 

Whoa, forgive me but I dont often troll the all motor forum.

I wana be sure on this, the HKS VQ35 cams will have the alignment holes for the VQ30 sprockets in them out of the box? To use these I need JWT spacers?

 

NO I had to mod the cams too work it required redrilling the intake cam hole

 

You modified stock cams? A post above by BlackbirdVQ indicated that the HKS cams come out of the box with pin holes for both applications?

 

they have VQ30DET cams which are used on both VQ35DE and VQ30DET, by HKS. Tomei just released their 268 deg 10.5mm lift cams, they would require redrilling of the dowel pin hole and JWT spacers.

 

I can't find any info about HKS cams on there website.

 

Quick question which if any tomei cam would be better for some low -mid range HP and TQ. I am trying to get my pick-up off the start.

 

Ok I think it's official as some of you may have already read but if not the car is running fine and cams sounds good.

 

What would be the benefit of using VQ35 cams into a full VQ30? Im waiting for someone to do that and dyno it to compare to JWT's $1000 cams.

 

10% more valve lift.

 

what the difference in lift between the stock z cams and the 4th gen cams?

 

What about the 3.5 Stock vs. Tomei vs. Nismo vs. JWT vs. 3.5? Would the 3.5 valve springs fit in our heads (if there are different from the 3.0) as oppose to spending $$$ for the JWT valves springs?
