The Official LS Swap Info/Questions Thread
Was looking at your pics to see the mods that were done to see if I can run the best parts of both our setups together and then have another LS-Z to sell to offset some of the cost. I figure it would cost as much or more to get a fully functioning setup done.
How you doing? ANy new rides or builds for you while I was away?
Same as always ... just livin the life. Had some other interests take a front seat for a while, cycled through a couple different cars too. Finally getting back into the Z and keep thinking about wanting more power. Once you taste 600+whp, nothing less is ever good enough.

Cass this looks like an awesome product! This "could" work if I can find the merged signal pin for the Nissan tach. If I had a schematic I could find out where the signals merge and what pin they are on the Integrated Circuit chip. Real easy from there to wire the SGI-8 D up.
Another note does anyone know what the protocol of the LS tach signal is? Also does anyone know what the protocol of the "merged" Z tach signal is as well?
The SGI-8 D doesn't say what protocols it cannot output. This is cheap enough to warrant an experiment!!
Cass I'm down for providing some development dollars as well towards this. I have an O-Scope and plenty of soldering materials to make it happen!!
Also we could buy a spare cluster to use as a development tool. I can/will put money on this as well. Are those inexpensive? I believe I can cover a lot of the ground work if I can get a schematic and the protocols of the two tach signals. I can try to duplicate both protocols in software to test as well. Then once the parts come in I can start doing some tests on the test cluster.
What do you guys think?

After blowing my motor I am craving more HP. Thinking either supercharged VQ or just going V8. Doing some research on cost and headache comparisons. How much weight is added to with LS swap? I plan on running NASA TT/PT2
My LS2 Z has a minimum race weight of 3320 lbs. That's with me in the car (220lbs), and a roll cage (~80-100lbs). I'm current set up to run TT2/ST2. If you want more info/details PM me.
Hello everyone I have a 2005 350z Grand Touring edition. Right now my Z has 65k miles on it and of course I want more HP lol I have been looking at forced induction but of course I have concerns considering my motor is very high compression. Ive heard of people doing LS swaps in these cars but honestly my main concern is losing luxury's that my Z has. So is it better to rebuild the motor I have now and put some TT's on there or just go ahead and do the LS swap. If I do the swap will I lose the luxuries my car has came with? AC,Digital gauges...etc. Thank you so much in advance. Also if anyone has done the LS swap could you list an average price of the build.

This topic has really been beaten to death. The best option is to either sell your Z, buy a Vette and put up with the poor build quality. Or rebuild your VQ with a built shortblock and FI app for big bucks...
Im struggling with understanding the wiring with my swap. I have PSI's stand alone harness but which Z wiring stays in the car? I know I dont need the vq35 engine wiring but all wiring seems to run off that main engine harness. would appreciate some help. thanks
Lots of good info on wiring up LSX swaps on that site.
