Sikky 350z/G35 LSX swap
All our ceramic coated headers come with a v-band flange pre tig welded on since welding to a piece of metal that has this coating is very difficult and messy even after cleaning it off. The non coated headers come with no flange so you can install whatever setup you want when you fab your exhaust. The outlet on the 1 7/8" headers is 3 1/2". There is 1 O2 bung pre installed per header for the primary sensors. If your looking to add wide band sensors you can add another either in the exhaust right after the header connection or add to the header itself. Added some info to the site....thanks for the $0.02 

i wish some one would do a write up on wiring this set up.
working on it. taking quamens advice and utilizing z stuff.
he is on a standalone but has suggested i try the following, as he did (were both doing throttle cable as opposed to drive by wire)
retrofit coolant and oil pressure sensors using factory nissan harness
retrofit alternator/starter using nissan harness
maintain factory nissan ecu
using a factory gm ecu (im on the e38) and harness (mind im using a t56), connect the proper connections, and get a fuse relay block. wire up the relays to be powered up by the factory nissan ecu. this would be done i assume by using pigtails off the nissan harness onto the ls harness. im figuring out which wires are required currently. my factory harness is basically nothing now, few sensors and wires.
if you go with an ls2, or drive by wire setup i believe you can use the CAN and flash them both?
if i am wrong on the wiring idea, somebody please correct me, or if there is another way to wire it up without a standalone, please let me know! the idea behind the retrofitting is to maintain the factory gauges, and start it up like factory, while the rest is powered off the ls1 ecu/harness
the more info and insight we can get, the better off we are at helping eachother out! no secrets here folks!!

i figure the simpler it is, the less electrical bugs to work out, because i hate wiring and electrical riff raff
so we have to send him both wire harness and ecu"s (ls1 & vq) or does he have a plung n play wire conversion that ties into both ecu. cause im way to far away to haul my car for him to wire it up. it would be nice if he offered both, wire manual with kit or just pay them to wirer it up. i just like saving money when its something i might be able to do my self.

"Basically our wiring service covers everything you just mentioned. The wiring tech will take both upper/lower nissans harnesses and the ls1 harness and wire them together to make everything work."
i would imagine its 500 including both harnesses, not that bad of a price really.
after my tune at CIN and i put my eyes on Cmytailsblink car im really really leaning towards a ls1/2 swap. However after putting together a few prices for myself of course thats just fast searching not trying to find deals its gonna b quite expensive. idk what to do with my turbo fund

I know they do the wiring harness, but last time I checked with them via email it was less then 500.. I have the email.. It was about 100 more then the one they offer for the S13/S14s
I talked with them yesterday. The wiring harness service they offer only really gets you a working engine temp gauge and a working oil pressure gauge. Your tach will still not work and your speedo will always work as long as you leave the nissan ecu installed. My understanding is that it is pretty damn simple to get the engine temp and oil pressure working with the LS engine. I'm not paying $500 bucks and probably add a 2 week delay to my install for that. Hopefully I'm not eating those words in a few weeks.

On a sadder note I tried to order my Sikky kit yesterday and my freaking card has been canceled due to a merchant having my info compromised. I'm glad they are looking out for me but I need to get my new card before I can get my last pieces ordered. Oh well...
Guarantee retro fitting the sensors will work. The stock Z coolant sensor threads right into the stock LS coolant sensor location on the side of the driver side head. The oil pressure sensor requires an adapter. Should be M16 to 1/8" BSP if memory serves me correct. I just bought an M16 o-ring plug from a local hydraulic parts store and drilled and tapped it for the 1/8" BSP. Then just thread the stock Z oil pressure sensor into the block.
