what would you guys recommend me do to maintain my engine? i was thinking change my plugs, wires, rotor cap, my fuel injectors, flush the engine with sea foam, change oil and filter, and my tranny fluid. anything else you guys recommend me doing?

 

Not driving @ 5k rpms constantly. If you do I hope you plan on taking some 1hr or so long breaks. But besides that what youve stated is the best you can do w/o buying a crate motor.

 

Why on earth would you be @ 5k constantly? gonna travel around 90mph? Slow down or take another vehicle.

 

haha yeah, i was going 90 the whole way. i had to stop ever 130-150miles for gas. it was about 30minute breaks in between. the first day i got back, it felt sluggish, because i was packed with stuff inside to the top. but now its coming back to its state it was in before. but i still need to change those out anyway. but right before that seems like my injectors were going out anyway. doesnt help when i have a 4.4 final drive either.

 

I think theoretically it would wear your engine out sooner but how much, who knows...
Id definately change your oil and do a full tune up before you travel that long. Ive driven my car cross country twice with a jdm itr tranny so I know how bad it sucks. LS 5th gear helps alot though, you should do that one day...
Set your tire pressures a little high too...
Have a safe trip

 

I'm pretty sure I can do 90 Constant without going 5k O.o

 

5k???...
u definetly have to keep it lower than that to get better mileage as well as not get a ticket i would think...id just cruise down at 55-60 to keep it just right

tuneup doesnt sound like a bad idea though...i would do it..ive taken long trips like that so good to always be prepared

 

I drove 4000 miles, from Washington to Nebraska and back, 400 miles after building my 2.0L. I changed the oil right before I left, and right when I got there. I also have the ATS Final drive, so cruising at 80mph is roughly 5000rpms.

 

yes i did do a tuneup before i left. and no it would have not gotten better gas mileage at a lower speed. it took the same amount of load at 5k rpm at 90mph as it would at 70mph which is the majority of the speed limit. i tried it out and the same mpg would show.

 

i love road trips although each time i do go on one i rent a car. its safer all around, it breaks down they give you a new one, it gets stolen, they give u a new one or you get in an accident its like whatever... i dont think i wanna drive to bumb F egypt and get my hatch stolen...

Have a Safe Trip Tho

 

the trip was done before this thread. i was just wwondering what you guys would suggest. but i just sea foamed it yesterday. a lot of smoke. haha and car runs smoother again, a lot quieter in the head, and i can beat 350zs again. haha. but around 7k and up it is a slight bit slower revving than before it seems. ill see how it goes later after the oil change, tranny fluid change, ignition changes.
