Sikky 350z/G35 LSX swap
the oem gauges are an orange plastic, so no matter what color led you put through it the cluster will still glow an orange hue. the black cats come blank, and whatever color you choose is the color that shows through. i have a luxeon white conversion onmine, and going with the speedhut tach that matches this as closely as possible. even if the stock tach would work, the speedhut setup looks so much better.

Pearl white faces with blue numbers and blue LEDs.
Havok, what color combo did you choose for the speedhut tach? yours looks very close to my gauge colors.
Why would Hinson advertise and sell a product that doesn't work? SHADY
Confirmed on everything Havok said about the tach signal, it goes to the box behind the AC controls and then through the data chord to the cluster. I'm not loving the idea of ripping into my already modded cluster. I have a spare one that I will mount the speedhut tach to and then send out to a friend and have all the LEDs converted to match the Defi blue racer gauges.
bbs - post a few pics of the wiring harness when you get it back please. Does SIKKY run the new tach wire into the main harness when they do the wiring work? Where is the crank sensor on the LS?
Lastly, anyone running Defi gauges in the center console? My oil pressure gauge just fit in the console before running out of wire. If the pressure sending unit is on the drivers side I will have to rewire everything through the smaller drivers side firewall grommet. So many questions
It's the same way Ryan wire his up since I'm pretty sure he got the instructions from me. BB trust me when I say you wont have any problems with this part of the install if you're going to SpeedHut route. The install is simple and you'll only need to run one wire through the firewall. If you're really concerned about the wiring then here are a few options that I know of.
1. Call Sikky from their complete wiring service. Note: How mine is wired and looks stock.
2. Painless sells a complete wiring harness kit for the LS motors for people doing LS swaps. Note: Buy a whole lot of split loom, electrical tape and brush up on your soldering skills. http://www.shopatron.com/products/pr...er=60008/302.0
Did I mention that this option is nasty expensive?
You gave me the part number for the gauge but I'm running a full standalone so mine was super easy. Just ran the green tach wire from the Electromotive TEC-GT to the tach and done.
Not true, the Black Cats can be made to order. Here is what I have:

hinson never sells things that work anymore lol
and cass ill send ya pics asap. the crank sensor is located on the back passenger side and sits below the starter, and i need a place to mount my boost gauge, as my wideband is in my door vent and i hate pillar mount gauges
quick question, there is a ls specialty tuning shop about 45 minutes from me, would i have to buy hp tuners and have them tune it, or could i purchase credits through their shop and have them tune it (assuming i only use 4 or so of the 8 supplied credits)?
i have a very basic understanding of how the credit system works, but im a bit hazy if i actually need to purchase the software and then pay them to tune it

Quick trans question.
I like to do all three AutoX, RR, and Drag racing plus my car see allot of street use, because there is almost no snow (South Carolina). I'm going to splurge a little on my engine and trans. For the trans, what gear ratios shuld I choose with everything in mind?
2.97, 2.10, 1.46, 1.00, .74, .50
or
2.66, 1.78, 1.30, 1.00, .80, .63
Or will I not notice a difference with either?
Thanks.

Just got some more info today on the swap and want to see how others are handling these issues.
1. The AC controls on our cars will no longer function (I am waiting for clarification on if its just the on/off function or the whole setup). How are you guys planning to deal with this issue?
2. The VATS system on the LS needs to be bypassed. JE Performance can do this, anyone know what they charge for the service?

I'll shoot them an email and report my findings.

You first gear set is more of a cruiser gear set and the second is more of a road race gear set. I'm personally going with the T-56 Magnum with the second gear set. Beware! T56 Magnums will not accept the Sikky driveshaft or the shifter. The magnum has a 31 spine output shaft vs 28 spline and it's 1.7" longer.
I'm still using the Sikky just having it modified.

Regardless I'll do a write up on a T56 Mag install. when I'm done.

Thank goodness I have a box truck with a liftgate or getting this off the delivery truck and back to the house would have been an adventure.

I thought I read on the LS forum that your second choice was the more popular.

2. The LS VATS isn't a bypass. I'm pretty sure its turned off in the tuning process. Should be able to turn if off with the HPTuner.
