I have the jwt 700bb kit and its great. The turbos spool up quickly and there isnt to much lag. But also if you go with the greddy kit and you get the 18g wheel turbo and feel you need more power you can always get a 20g wheel with slight modification to the compressor housing instead of getting 2 whole new turbos. My brother had the greddy kit on his 350z and it ran great untill spun a bearing a there were metal shaving in his turbo and oil pan.

I heard they downgraded the turbos in their tuner kit...never heard they sold knock off stuff...
I have had nothing but good luck with my APS Extreme Kit...my turbos are genuine Garrett BB turbos.

Hi ALL,
My first G, I had APS single turbo. That kit gave me a lot of troubles...from oil return issue to oil passing through the turbo into the intake
. I sold this car in 2006.
About a year later, I returned to the G family again. This time, I bought 2
. My current Gs, 03 with JWT 700BB, fully built motor, 6spd, pushing 510 WHP at 15 PSI with Haltech. This kit is great, no trouble so far...17+ months now. For DD, I use map A for 450 WHP @13 PSI. It took me a while to get use to the power it has. It sounds so so due to the fact that JWT has cheesy BOV.
My other G, 04 with Greddy 20g with stock engine running 5psi at 380 WHP, using Greddy E-management....6spd, very low milage under 13k. I like the way it sounds (external waste gate, BOV etc..) better than my JWT. I drive this G only on nice weather. To pick one of the above, I'd pick the Greddy ones. I like their BOV sounds, large external waste gate, 3.5 " thick FMIC, high polished pipings, simple design and no need to have JWT authorized dealers to do the installation. my 2 cents Ned

. It can be replaced by removing 2 hose clamps. I replaced mine but only with an upgraded recirc valve to be sure it would hold 21psi.... I can't stand all of the little ricers with the super loud BOV that go off at 5psi!!
