We are happy to announce the 350z/G35 LSX kit is finally complete! This kit will allow you to bolt any LS series engine into your 350z and G35. No cutting or welding required. We decided it would be a good idea to show everyone just how easy this install is with our kit so we took a fairly stock G35 and began the install. Here are some pics and info to better show and explain this setup for those interested.


Here is the donor car, prepped and ready to go with the OEM engine and trans removed.

Donor LS2 engine and 6 speed manual trans from a 2006 Pontiac GTO


First step pull the stock GTO oil pan


Here is the new high capacity Sikky oil pan. Prep the new pan by pre installing the gasket. This pan is equipped with windage tray and trap doors to eliminate any oiling issues associated with the factory GM pans.



Installed Sikky pan showing connections for remote mount oil filter kit that is also included with the mount kit. Factory dust shields are also installed.


Installed Sikky billet aluminum driver side motor mount and urethane bushing


Installed Sikky billet aluminum passenger side motor mount and urethane bushing


All prep work complete on the engine and ready for install


Installed Sikky trans mount bushing


Begin install of new engine and trans. Install is as easy as bolting up the VQ with our kit.


Engine and trans installed with engine bolted to factory cross member

disconnect steering shaft for header install


carefully slip Sikky long tube headers into position around steering column and re attach U-joint

Excellent clearance


Oil filter relocation lines


Aluminum drive shaft installed

Sikky billet short throw shifter, standard with mount kit (over $550 value)


bottom of shifter, complete housing machined from one piece of billet aluminum


factory shifter placement, with threading for factory 6 speed **** Super Clean!


factory fit, ultra low engine placement= low center of gravity


almost done.

 

love it. I love Robs (black Z) That has your kit done with his LS2!!

 

pretty bad ***, congrats great work

 

that is a NICE and well thought out set up. I love it! Makes me think twice about what I want to do to my Z...

is this DE, HR, or mounting locations do not actually differ between the cars?

 

Very sweet!

 

video! looks sick. What's the rough estimate value of this as a package? w/ engine or w/o engine? Just to give everyone a rough estimate?

 

kick @rse!

 

subscribbed. This is awesome.

 

Very nice! You guys should give me a heads up so I can start chiming in on these threads.

 

in for pricing

 

Increadible! I've stopped all other projects to save for this.

> How about the fuel system? What pump upgrade is necessary?
> Is there an interface between the GM and Nissan ECUs to allow the use of factory gauges?
> How about the O2 sensors? I assume they connect to the GM harness and give feedback to the GM ECU. Is there anything that needs to be done to prevent it from throwing codes?
> Does the Sikky kit work with any GM LSX engine or just the LS1 and LS2?
> What other donor parts are necessary.

(Sorry for newbie questions ... Search is my friend but I see such a scattering of information. I'd love to see this become a DIY thread. It almost is already.)

Keep up the great work Sikky!!

 

Im saving up for this as well...

Turbo? SC? - no thanks - LS2 NA FTW!

 

Whats the weight difference?

 

Complete Package price?

I'll have to stop by your shop one of these days, I've seen Rob's and James' LS swaps, both look incredible.

 

Sub'ing for more answers...

 

My last weigh in was a little over 3100lbs.

 

Give James or Chris a call at JE Import Performance. Their quote was pretty much on the mark without the BS you'll get from other shops. You'll get exactly what you need.

 

The weight actually works out a bit better with the LS engines over the OEM VQ setup. We have the info around here somewhere from the scales when we originally finalized the engine location. I will dig them up when I can. Common misconception with some of the other kit manufacturers is that the engine needs to be slammed into the firewall, but the scales show a different story. We spent a lot of time with the positioning of the engine and we ended up locating the engine in the best possible position to ensure it would improve on the handling of the vehicle and remain a bolt in swap. The center of gravity is drastically improved and if you notice in the pics that the engine is very low in the engine bay. When measuring from the factory strut bar on a 350z to the top of the OEM LS manifold it has nearly 6" of clearance.

 

-A factory fuel system will work great with this engine in most NA configurations. The setup in this build is a stock fuel system with a fuel line setup that makes it plug and play. Or, you can run upgraded systems if needed, but it's really no different then you would do for a turbo VQ setup.

-All the factory gauges work except the tach at this point. We have several solutions for this, but we are still testing to determine which will be best. Most people have just installed aftermarket tach's in place of the OEM unit. Looks clean and OEM, and works great. Maybe Havok can post a pic up of his cluster to show everyone. He has this same setup.

-The kit will work with most LS based engines, even most of the 5.3 LM engines. Some LS3's have a different front cover and oil pan, but we are working on that issue right now so in the future it won't be an issue which way you go. Right now, the transmission needs to be a T56 6 speed because that is what our bracket is designed for. We are working on the bracket for the Auto trans that is standard in the camaro/firebird/gto.

-As for other parts, there is not much left. The stock radiator and fan can actually work with some mods. We have some cooling system packages we are testing for both the G35/350z kits and our S13/S14's.

-For anyone considering this swap, typically you can spend around $15k done and driving. Obviously it depends on which engine you use and if you upgrade or add on anything not neccessary for the swap. Most people end up upgrading some items. But, as anyone knows out there, to build a vq motor and boost it with all the required upgrades to both the fuel system and engine management you will end up spending more than $15k. An LS2 setup basically stock, super reliable, starts and runs like a factory GTO with the skin and handling of a G35/350z with 400 wheel hp can't be beat when it comes to dollars spent for hp gained. Then the cheap cost of upgrades makes it even more appealing.

 

looks great!!
