Rear end links and camber arm
Fast Intentions 2.5 inch exhaust. 18 inch resonators.


K sport coils
K sport coils and spl front control arm

Spl front end link




3780 with full tank of e85 and no driver. 8 week old German Shepherd puppy

Rear toe arm. Deleted the spring bucket on both sides.






































Magnetic oil drain plug broke in half lol






Oem tow hook painted back with hole dremeled out. Planning track day soon




Got the engine cover painted color code QAA (moonlight white)




Where the stillen headers are hitting the steering column?




Stillen said it will be around a month before they can get new ones sent to me with correct clearance. In mean time they told me to take a hammer and put a dent so I can safely take right hand turns
The z1 headers that don't fit..... <br/>Driver side motor mount on the X will not clear the first header run




Plugs at 44k. Not in that bad of shape, but need step cooler for nitrous. No oil found with spark plugs.(I have seen a few that have bunch of oil on top of plug.)



Oem gtr plugs (do feel difference on butt dyno) Ran out of track. In 6th with 2200rpm left and still had all of 7th! Never been over 120 before this in my g.really cool air field. I'll have to go back for some 0-150 videos after nitrous in installed




This part bolts to the oil filter bracket from the hose
You can see the light coming in. When I drained oil I was a quart short or so. Luckily I caught it after it happen. Smell was terrible. Hot oil all over a hot exhaust!

New one was $30 and is a completely different design.

The adaptor for my z1 oil cooler blew out causing a lot of jmy oil to spew out

Looks great man! Z1 should sponsor your car with all those parts from them!

Can't wait to see the NOS tank installed! I don't think I've ever seen a G with nitrous yet How much nitrous are you planning on spraying?

Would like to do 50 shot in each intake. But I might just do a 75 shot to be on the safer side.
I'll be leaving it up to Jon at z1 to work his magic. Still deciding if I'm doing the window switch or the wot switch. I'm leading toward the wot personally

Hahahah you have been consulted on many of these mods before they were installed. Thanks for your help my cars really coming together. Can't wait to take it to the track and get a 1/4 mile run in before the nitrous install for comparison

I have no dyno results with it on but I came from the k&n typhoon. I like it a lot for me I knew it had to be a long tube intake. This was my setup before I swapped them. I recommend them or any long tube intake.

This was before the z1 intakes. The sound is better with the z1. The k&n had a whistle noise to them I hated that

Are you going with the Nitrous Express kit? 100 shot? I was going to do this, but I was;t able to find a tuner to tune it that felt comfortable. I hope this works out well for you We have a lot of the same mods.

Ya foreal lots of same mods. I'll be finding out more info in a pm about the trans setup and pricing.

Yes I'll be doing a 100 shot.
I'll be putting in this stuff myself before I drop off car to save some cash.
-one step colder plugs (maybe gtr? I think they might me not step cooler but if they are that's what I'll go with)
-bottle warmer
-blow down tube
-remote bottle opener
-purge
-running whatever lines I can without actually hooking anything up lol

Kit that z1 recommends is the zex kit for the 07-09hr. Honestly haven't bought the kit yet. I'll look into the nitrous express. Any major difference between the 2 kits?

ZEX is solid. Nitrous express seemed to get better reviews when I was looking to do this. I hope everything works out well with your install.

Just wondering if you have had any luck with your Nitrous system. I have had 2 kits on my other cars but never pushed more than 100 hp on the highest which was on a 99 dodge dakota r / t with the 5.9L V8. I have always been told that basic rules of nitrous are around 30hp for every 100 factory hp was thought of generally safe. But don't like the idea of that much nitrous in a smaller engine even though the g37xs I have is rated for over 300hp and my dakota waz 250 but had 350tq. Just wanted to find out what the results are.
