Ok off the top of my head this I need/have yet to do:
For the turbo/engine and engine bay setup:
BOV
Clutch that will stand up to a GT35r on 9-11psi
I need a reflashed ecu or my current one reflashed
Side feed injectors
S14 Walbro Fuel Pump
S14 Catback 3" Exhaust (to be fabbed by me)
Engine needs to be rebuilt or I just need a good bottom end with lower compression pistons.
Powdercoating of parts (To be done by me)
Engine bay shaved of all unused bolt holes and such and coated (to be done by me)
Interior:
New S14 carpet
Drivers side 350z window motor
350z drivers side power seat rail
Re-wiring of interior harness (to be done by me)
Queitcar Spray in coating (to be done by me)
Exterior:
JDM S14 Zenki Sideskirts
Power sunroof
Paint (to be done by me)
Replace all windows and new seals
Rear wide body panels
Suspension and brakes:
Brembo 350z brakes or Z32 brakes
All new brake lines and fuel lines
Install energy suspension master bushing set
Then there is wheels and tires obviously
On a lighter note, I am going to get my friends parts S14 off him so my suspension will be pretty much squared away as I plan to just use stock s14 suspension with upgrade polyurethane bushings. The majority of my current suspension is missing because alot of it was bent.

The paypal is where people can donate $100 if they feel they want to do so. I have had that up there for almost as long as I have been on this forum. The donation idea came later.

how many names are on the list so far? if this is actually going to happen, add my name. then let me know when its time to donate! i will be doing a similar build (vq35 into my s14) next spring. so id like to see this done before me!

Newest update:
VQ35 out.... Tag in VQ30DET.
I have been talking with my best friend who decided to ditch his S14 project that I had showed earlier in this thread. I have been talking to him and we are working out a deal to where I will get his VQ30DET from him.
WHY? Do you ask?
Low milage, JDM. Already built for turbo.... Which means no rebuild to be had to get this car running. Which = Big chunk taken out of projected costs of the project.
For those of you that dont know, info on the vq30det was covered earlier in this thread. Its basically a earlier turbo version of the vq35. Since they are so closely related I should have no problem adapting all the sensors from a vq35de to a vq30det and still use a reflashed VQ35 ecu. If I am right this could be a possible swap for 350zs and Gs.
If anyone has questions feel free to ask.

Can the VQ35de ecu really work on a turbo VQ30? What about using the larger intake, maf, and headers off a VQ35 on the 30, will that work, and if so will that give you better power and mileage?

With some re mapping it should work which is what I would have had to do to begin with. Headers are interchangeable with the VQ30 I know for a fact. I will be using the intake manifold I originally made for my VQ35 on the VQ30 which is a VQ30 manifold with the original throttle body removed and a new VQ35 throttle body flange was installed in its place. This is better anyway because the runners to the VQ35 head to the VQ30 intake manifod did not line up perfectly, enough to make a seal with a gasket but not a smooth even flow type line up. Overall the forge internals alone make switching motors worth while. I will be sacrificing the better flowing VQ35 heads, but it is what it is.

So after some brainstorming with my friend we have decided to do a VQ30DET/VQ35DE combo. Meaning VQ30DET bottom end and VQ35DE heads. Should be a great bottom end for turbo and great flowing heads as well. Here are the specs for the VQ30DET for those who are curious:
Taken from Wikipedia:
VQ30DET
The 3.0 L (2987 cc) VQ30DET is a turbocharged version of the VQ30DE. Bore and stroke remain the same at 93 mm and 73.3 mm respectively, and it has a compression ratio of 9.0:1. It produces 270 PS (200 kW; 270 hp) and 271 ft·lbf (367 N·m). From 1998 onwards, it produces 280 PS (210 kW; 280 hp) @6000 rpm and 285 ft·lbf (386 N·m) @3600 rpm.
Should roughly make it a 3.3L if I am not mistaken (Dont know all the math involved to be completely accurate)
The plan is to take the VQ30DE heads and put them on the VQ35DE bottom end to make a high compression 3.3L for the next project which will be all motor.
I am getting excited I pick the VQ30DET up sometime this week. Still have to work out some kind of payment plan with my buddy cause I am still broke dick.... lol.
Still need a 350z firewall folks if anyone knows anyone with a parts 350z that wouldnt mind whipping out the old reciprocating saw...

It seemed a better option than sourcing rods and pistons for the VQ30 if the original rods can handle the extra boost.

I am interested in seeing how this turns out. I have a VQ30DE that I am trying to figure out how to do this on. I was under the impression however that the 35 heads will lower the compression ratio due to the different combustion chamber design rather than change the engines displacement.

I know the engine mounting points are the same so I know the VQ30DET can be swapped into a 350z pretty easily. Turbo setup clearances might be an issue tho.
I should have probably clarified that this is going into a 240sx I have an s13 but I'm starting to think that that shell is going to take more work than I'm willing to put into it so a new one might be in order.

Sounds like an interesting setup. If budget would allowed, I would see if you can get VQ37 heads or even VQ40 heads and the are suppose to be even more freer flowing(at least that what I read).
