Mark, One of these 2 guys can help you with your Aero Designs: http://www.hurleyracingproducts.com/index.html or http://www.dauntlessracing.com/

Not sure where you live, but I am selling a VQ35DE from a G35 with a 6 speed. Here is the link: http://forums.hybridz.org/index.php?/topic/93330-vq35de-6-speed-tranny-for-sale/ Just for information, Jeff

You won't loose VVT if you go with Haltech.

Also, Z-Fever has a wiring harness modification and ECU flash which does away with all of the extra NATS, etc... stuff you need, making the swap a lot easier.

Don't forget the drive shaft. You need to yoke. Jeff

It might be the bushing "bearing" the yoke rides on inboard of the seal.

Question about the ECM programming. It sounds like a modified wiring harness is needed (if only to get rid of unnecessary loose ends). Do you supply instructions to modify the harness when the ECM is re-programmed? Will piggy back controllers still work properly with a modified ECM? Thanks,

Thanks, please keep the updates comming!

Mark, What are you using for the front suspension? A-arms and hubs/spindles? Jeff

If you search through the VQ 35 threads you will see that someone has done this with Z-Fever recently and they are very happy. It looks like it works as advertised!

I have a 2003 G35 VQ, and it did not come with a mechanical fan.

Great news, Thanks for the information!!

Here is the link to his build. He is using Autronic, not Hal Tech. Hal is the local tuners first name. http://www.midsouthscca.org/index.php?name=PNphpBB2&file=viewtopic&t=112&postdays=0&postorder=asc&sid=e771acfc3d9a55553c3ad689c4e3128e

Yes, I was looking at cams as well, but at $1200 - $1500 for cams and springs, that isn't going to happen very soon. I think I am going to get the engine in the car as get it sorted out before tyring to switch heads/cams. It has been great watching EMWHYR0HEN's build! I hope to have enough money saved up to get my engine in during the 2009 winter season. I didn't get all of the wiring I need to run the stock ECU so I either have to find another donor, or go with an aftermarket ECM.

Looks great! I've always liked the idea of going back into the cowl for the intake. Keep us posted.

Check out this build. It is for a race only car, but very nice. http://www.midsouthscca.org/index.php?name=PNphpBB2&file=viewtopic&t=112&postdays=0&postorder=asc&sid=0524960c3c8af00ea21d58952c077a2a

That may be a good option for me as well. Is the chamber volume different on the Rev-Up cylinder heads, from the non-Rev-Up heads? The factory lists both engines as 10.3:1 compression ratio.

Thanks for the replis, guys. Here is what I found out: YES, the Rev-Up cylinder heads will bolt onto a non-Rev-Up engine. You just have to get the connectors for the additional cam control circuits. This is an engine which will be going into a race only car, and I have not fully evaluated the stock ECU route. But I don't want a large amount of extra wiring in the car just to make it work, plus I would still end up adding a piggy back type of controller to the stock ECU. My reasoning for trying to go with the Rev-Up heads, is to get the additional power available in stock form, and to give me an extra set of cylinder heads for back up, and to maybe allow me to mill the heads to get the compression up. I will need to check the valve to piston clearance before acting on this one. Does anyone have any input here? There are 3 aftermarket EMC's which will control both cams, but not the drive by wire. They are Haltech, Autronic, and AEM. There may be more, but this is what I know so far. They are all in the $2500 price range, complete. The Haltech and AEM ECM's have good base programming already avaliable. The Autronic ECM should be ready in another month or two.

Does anyone know if you can install 2006 Rev-Up cylinder heads with cams on a 2003 non-Rev-Up VQ35DE, and control the cams? Planning on using an aftermarket ECM. Thanks.

I have not had a chance to look very closely at the stock crank pulley on the VQ, but there seems to be a move in the OEM engine designs to use the serpentine belt as the dampener. The crank pulley is usually solid, and the belt and belt tensioner take up the harmonics. Whether or not the engine is internally balance doesn't determine the need for a harmonic balancer, it is the harmonics the engine creates during operation that require the use of a harmonic balancer, and that changes with RPM.

Hi, Does anyone know if Saner Performance is still around? Their web site has not been updated in almost 3 years, and they have not responded to my e-mail. I am very interested in their adjustable front sway bar.
