well i have an 02 altima 3.5 SE. These cars are lil bigger then that honda you had kevy kev. lol when i bought mines i was like dayumm this a big ass car. But hey more room for more hoes...lol
1) The build quality is pretty solid. some people say the interior looks cheap. myabe in the 02-04 but the 05+ looks a lot better. as far as suspension when it's lowered it handles very good. but notice stock the rear sits lower then the front because the fenders are bigger on the rear. I would use tein springs or coilovers. I have eibach but i will be swicthing over soon. as far as noises i havent really noticed any.
2) gas, gas, gas. I have intake, header, exhaust and technosquare reflash. I fill my tank up and it will last a week. One tank full of premuim is 60 bucks
3)hummm oil consumption. well my car burns about quart or two between oil changes depending on how i drive it. I just keep an eye on it. some burn some dont. BUT it states in the owner's manual that the engine will do this.
4) being that this is the same engine in the 350z and g35 just fwd. Its a torque monster. power is good. just be careful once modded you will be getting a ticket or two so be careful.
5) my tranny felt weak when i had my altima or shold i say my clutch felt week. Long engaugement, and wasnt gripping. I replaced it witha competion clutch stage 2 clutch. damn thing grips good

but stop and go traffic isnt fun. Nissan has some ****ty slave cylinders and clutch master cylinders. I have replaced my slave cylinder but im working on replacing my master. I dont know what years these apply too. but i have heard guys on nissanclub.som say all years are like that.
6)well lets be real this is one sexy car. well to me it is. i love the exterior and i love the interior. very comfy on road trips. Wish i had leather.
7) im satisfied with my whip. need some suspension work and extrior work but other then that. she has been good. Had it for three years and put about 80k miles on it. only had to replace the maf sensor, battery, starter and major tune up. did all this myself.
8) my loves are room car with good power. my hates are wish there was more aftermarket stuff available. also you plan on doing headers be adviseed that they have not been able to get the check engine light off of the 05+ models. also these cars come with a timing chain, i look these better.
they way your talking about hooking it up it will fa sho be a head turner. I will be doing some things to my car as well you will see in a couple months. I cant tell you though... ancient chinese secret
now rep me and sell me old parts when you start modding it
