Big step forward

Progress has been slow but the car can be pushed around right now Work on wiring up the gauges, wiring harness etc is basically under way now. The frame for the fuel cell needs a couple more brack

We have yet to sort out the belt/tensioner just yet. It sounds like a Juke belt might be workable. We are also relocating the oil filter to be remote and use a GTR type filter to work with the thermostat type adapter. Steering I think we had no major issues with, its primarily getting the engine in the right spot and having the right header design.

This is exciting to see! Was talking to a friend recently and have started reconsidering the VQ as a swap. Since I care more about something fun, than all out power, and I'm aiming to for a modestly lightweight but daily driveable car, the VQ fits the bill perfectly. VQ37 even more. I love the responsiveness of the VVEL system, though I know aftermarket support isn't the best. Most I have in my G37s is an Ark Grip exhaust and I honestly love the sound. It's a far cry from the "trumpety" reputation VQs have from cheap 350z owners straight piping their cars.

The  VQ37 to my knowledge doesn't have good support with full standalone, and simply would not require it unless someone wanted to go for insane power, at which point I really think there are better platforms (LS anyone?).  But the VQ37 with flashed stock ECU's also picks up more torque gains across the rev range than other VQ's. So for mild builds the potential to make pretty high N/A power is substantial with all the standard stuff that ought to be done in a swap (custom intake/exhaust/modified ECO with the security disabled, etc).  We used ZFever to modify the stock ECU for this service. 

I too was just wanting responsive high power motor that is relatively light, and reliable to thrash on. We should be over 400 bhp on this build but will do a custom tune before it is back on the road. Still lots of little shit to do. I will say that this swap is more of a pain than doing an LS, but I think in the end, since I have no intentions to sell the car for a long time to come, its important to get what you want, based on your own values and how you intend to drive the car.

Getting there, lots of tedious stuff to do. One thing I think we will do is order an aftermarket pedal set including one with DBW as the 370Z pedal is really quite awkward for the small foot wells. Looks out of place. Fuel is basically sorted out, oil sorted. We are going to test fire this engine with the clocked tensioner and belt before mentioning which belt we used just because we are not 100% it will not make noise with this set up we have and don't want to steer anyone in the wrong direction. But as it is, I am happy with the look, the belt is tight, I think it will work.

Dash is made by retrospec, definitely had some extra hours put in to making it fit this good, hope there are no major issues with gaps when we have it all done. 

 

 

Is he still in business?? 

 

I've heard so many horror stories about poor communication and many months of lead time. Sadly only other carbon dash options right now are Carbon Signal in the UAE. Tough pill to swallow

Not sure if they are still selling, the website is up. Fitment was not as advertised, definitely takes a lot of work to make it fit anywhere close to as good as stock. Unfortunately they also shipped gloss finish even though matte was requested. So it created a lot more work to refinish. You do not want a shiny dashboard, seems not only like it would be annoying but unsafe.

Couple more pieces back from powder coating, that cutout above the fuel cell we will basically just glue it down since it is not structural anyway. 

EDIT: Tried to upload a video of it running, apparently the file isn't compatible with the forum, though it does start and run! 

We need to get this thing tuned properly before it is driven again, ended up getting an Ecutek so we can tune with that given the cam changes (JWT C2).

Got the fuel cell from Fuel Safe and the surge tank/pump from Radium. We will probably get our pedals figured out when the car comes back from paint which its going back there next week. Might just get some Tilton pedals and I think the sensor from the factory pedal can be swapped into a Tilton DBW pedal somehow.
