newb with a Question
this is my first ls1 and that being said I know not that much. I do know that living in Wyoming takes alot of your horsepower away because of the altitude and my question is what mods would best fix that problem and help gain the the lost hp due to the thin air and such so far I have thought that a cold air intake and the free mods and some exhaust work would be the quickest way to free up the system and I am not looking to blow a lot of cash on this one just looking for something that will help me to spank a friend who is running a stock 1998 prelude and thinks he can really give me a run. as of now the car has a new air lid and has subframe connectors but that is all the mods. If there is anyone on this board from wyoming I would love to know who so we could try and get a f body club going for wyoming
Any help or suggestions would be great

what car do you have? what year?
air lid, headers, ported tb, ls6 intake(depending on year of your car, '01 & '02 have them stock)
with all that thin air a turbo or supercharge would be nice, but they are spendy.

You'd have to give him a few carlengths to make it fair

That said, most people start with a lid & K&N / Air hog filter. You can also add some MAF ends. I put on a Granatelli MAF & picked up 1/4 sec & 15hp, but it pinged, so I put the stock elec on the Gran MAF ends & kept the power & lost the pinging.
For an auto car, the best thing you can do (without adding parts) is get a tuner. The Predator comes with a perf tune that you just downlaod. It adds timing, gets rid of Torque Management, and some other stuff. And you can tweak things a little too, like shift points, air feul, fan settings,etc. A Predator is a good way to get into tuning. Very safe! Buy it from RunninWithTheDevil if you get one. James is one of the best guys you will ever deal with.

K&N check
I have also wondered if the shift kit for the auto would help any or not just really looking for something that won't suck as much gas as my 400 but will also have the power to destroy the rice around and we have plenty I live close to the famous WYOTECH which is a rice and lowrider magnet. I was also thinking just for traction purposes only 17x11 on the rear and 17x9 on the front for the stance and the lock up when I go. she is not going to be flogged severely that is what I am going to leave to the 69 bird I have my eye on with a bored out 455 tubbed and ready to drag and the 78 is just my dream car so I am going to love her and keep her cherry. oh BTW I love my birds. well I appreciate all the help and support here and I will keep posting as things come up.
BTW the kid with the prelude is a good friend and well we are looking at a 3 way race me ls1 formula, him in a manual 98 prelude and, anoother bud in a manual 3.8 stang. looking to keep them with me and then let them have it. looking at a 1 mile straight no cops no nothing just us and a rice, ford and bird match. I will have the video posted when we do it

78 T/A 400 4-Speed. I had a 79 T/A 400 4-Speed.
400 Right not the 403 Oldsmobile? What color? WS-6
That will be a fun car to restore.

I suggest some long tubes and cat back. A free flowing exhaust will help scavenging and improve gas mileage. Plus you'll get the added power and sound. Port and polish your stock throttle body and throw an ls6 intake on it and you should be good to go.
You may or may not want a converter as it will decrease your mileage. Maybe if you keep it small (around 3000) then you wont notice too much decrease. This is the first mod i'd do to the car if it were mine.

Then start to mod it.
The LS1 is such a badass platform to build on...........welcome to the forum and enjoy the never ending quest.
Next, I have to agree with all my buds here and say you should SMOKE your friend in his qualude, er, Prelude, without doing a freaking thing to your car.
I would just do all the free mods you can at this point. My T/A is my daily and every thing I did to it only improved drivablilty and mileage, except the 3600 Yank. That took my mpg from 21 down to 14. But I have learned how to drive it now and it is around 17 if I just go to work and back with it. Free mods and MAF are for real. LS6 and 90mm TB might be a bit much for you if you are just going to use it for a daily driver. That being said, anything you can do to help it breath (in and out) would be good.
