Did you make the intake and MAF mounting piece? Looks really good
Thank you.

As far as the MAF mount goes. I just cut the stock MAF housing and tubing (mount) out of the OEM intake box and matched the aluminum tubing to it. That way it maintains the stock MAF scale in the ECU's VE tables. That keeps all the electronics happy and the ECU has the ability to adjust fuel and ignition appropriately.

Nice work sir! When will we see the dyno in this? And how did you get approval from the misses?

Sent from my SM-G935V using Tapatalk
Thanks!

No AWD dyno's in my local area, have to travel to find one. The misses and I may go on a shop & tune road trip late spring. Until then, I'll be keeping the tune fairly conservative. For the most part everything that I have built and bought for the engine should balance out with a couple good street tuning sessions. May have to wait till I take it to the track to get any actual numbers.... ;)

Happy wife = happy life ;)

To me that is the biggest gain from adding a cold air/short ram intake. I could really careless about the 5-10% claims of any gains in power or MPG. I love the wide open throttle sound that you get when you put your foot to the floor. amplified once again when she hits 4000RPM+ when the VTEC and secondaries open up.

Sweet I'll have to look into tuning it as a FWD. Only videos I have seen on YT have them rolling on AWD dyno's and it seems as though the rear wheels are rolling all through the RPM range. I would assume this is what you are referring to as speed coupled? So the rear rollers are coupled to the front.

dopes6070, I forgot to list that I have KTuner. I have been playing around with it on the stock setup for a few months now. Pretty sweet software for the price.

I dont think you have the ZDX TB and ITBs. Did you mean you have custom Secondary butterflies?
I do have them both, However I am not running them both at the same time. I'll sort out the confusion here. The first post lists my "current setup", where I have the ZDX throttle body installed. The second post lists "Future Mods". Where I have built a custom set of ITB's to be installed sometime in the future.

MAC Kustoms J35 46mm Individual Throttle Bodies

Making of the custom 46mm individual throttle bodies for my J35 biuld

Had the lower spacer and the bottom portion of the upper intake manifold machined to accept my throttle bodies.

GSX-R Throttles

The fuel injector spacing on these ITBs is exactly the same as the stock J35 rails. So I purchased an extra set of rails. I have a modified set of GSX-R injectors and complete wiring harness to install as well.

Secondary J35Z5 fuel rails and 240cc GSX-R injectors mounted.

Rails and injectors mocked up so I could get the measurements for the aluminum mounting brackets.


by Chappy, on Flickr

Aluminum brackets fabricated and rails mounted to the GSX-R throttles.


by Chappy, on Flickr

The stock rails have the injectors pointing out from the center where as these are pointing in. This actually worked out in my favor as it took less fabrication to mount them this way on the throttles.

Complete intake manifold with lower intake runners mounted.


by Chappy, on Flickr

I will be using the stock injectors and fuel rails as well as these secondary injectors. May have to step up to a stand alone EMS for this one. The KTuner isn't going to cut it.

Or I just so happen to have a spare MegaSquirt III laying around that I may look into setting up for this build.... Time will tell!


by Chappy, on Flickr

It will only be for fuel and ignition, stock ECU will continue to control everything else. That is, if I can get it to work as a piggy back. ;)

Intake manifold modifications

Picked up my Non IAB upper intake cover this week. Preparing to paint it the same colour as the chassis.


by Chappy, on Flickr

Factory casting flaw removal.


by Chappy, on Flickr


by Chappy, on Flickr

Paint to follow.....


Also took some time to port and polish the upper intake manifold.

As much as ITBs are cool, my question is, what is the point?
F#@king right they are cool. That's my point. >:)

This is not a racing truck or a truck that will be raced frequently. I would imagine this is a full fledged daily driver with full interior and all the stock creature comforts.
You are 100% correct. This will not be a designated racing truck. However, if I can improve on the 8.0 second 0-60 and add 50whp... that would be sweet.

raced frequently... No. I will probably take it down the 1320 once or twice just for FUN. Because I can!

The investment of $$ and time made into the ITBs and ECU programming/piggy-backing, wont it be easier and efficient to go with a forced induction via centrifugal blower or a turbo?
I wouldn't say bolting on a turbo would be easier. Sure the power increase would be easier, but where is the challenge in that?

With the range of power that I'll be putting down, I'm pretty sure the stock ECU will work. Just need a few runs and a few quick tweaks with KTuner and I should be good to go. Only reason I am thinking of running a stand alone or piggy back EMS would be if I use the secondary set of GSX-R injectors. It would be easier just to tap and plug the GSX-R throttle body injector ports and stick with a single stage fuel injection using the stock J35 injectors and ports. If I use the single stage FI I will probably have to increase the fuel injector flow rate/pressure. Then make a few tuning tweaks. 30-60 minutes, 2hrs tops.

Realistically, all this work would add what, at most 50hp at the crank with some crafty fuel and ignition mapping on pump gas even with the proper exhaust, intakes and cams? How much of that would be usable at the wheels?
I'm not sure of the end result, but I'm hoping for more like 50WHP. And all of it will be put to good use. This beast is AWD and more than capable of putting 400 ponies to the ground. So 270-300whp should be no sweat. And fun as hell on the street. Hoping to put some of those over compensating, jacked up, never see the dirt, straight pipped, V8 super trucks in their place with ease! :surprise:

Dont get me wrong, a decade ago, I was hell bent on getting a forced inducted A20 motor with ITBs and a straight up CF plenum.
So why didn't you go through with it?

Your build is surely one of a kind and you have my admiration for having some serious steel balls to do this.
Thank you and really do appreciate your constructive criticism. It is food to fuel me to the finish line.:domokun:

Hey that's life and it happens. It's always best to put family first.

I am a bit further on in my life now. I am able to take some money and put it toward working on my cars. As well as tend to the needs of my family. I wasn't always able to drop money on these sort of builds. We lived pay cheque to pay cheque. And as far as vehicles went. We had to make due with just being able to barely keep a car on the road. I have always done my own wrenching so that has helped keep a lot of the costs down. :wink:

Finally two nice sunny days in a row. All the snow is gone so now it's time to start adding some parts!

Out with the old



by Chappy, on Flickr

in with the new


by Chappy, on Flickr

Added a set of yellow DRL bulbs while I had the bumper off.

I also took a few minutes to add my splash guards. Figured in this climate that these would be standard equipment. Guess not with the Value Package!

Unless I missed it, your build thread doesn't say what brand / spec wheels those are??
No you didn't miss it. I did forget to list the specs. :frown: I'll update that post now, thanks.

TSW® - Valencia
Gloss Black with Mirror Cut Lip
• 20" x 8.5"
• +35 Offset
• 5x120.65 Bolt Pattern
• 76mm Hub

They require a centering ring as they are hub centric wheels. The rings for these wheels where included as part of the install kit option that came with the wheels.
