first off, its on the first page, with many threads asking the same thing, secondly, your typing is atrocious, and you're a little late hopping on the band wagon arent you?

First thing you should do is get a cold air setup and clean out your throttle body.
Get a small brush and some carb cleaner and scrub around the butterfly. You'll be amazed how much difference that makes.
After that you may as well get exhaust. From there on though I would focus on suspension and stiffen it up some so it slides easier.

ok well thanks for the nissan help and the grammer lesson

but not knowing anything about nissans i dont know anything about the k377628 or w/e engine swap or an intake for a kj2728k or whatever you call em so i was hoping someone could help me out with what mods i should do and where to find information

the car already has a full 2.5" exhaust with the cat removed so i think the intake and clean the tb will be next

the intake wont do much, only make it louder, personally, i would leave the engine alone for now, unless you wanna do a UR underdrive system, and maybe headers, and as far as headers go, hotshot is the best, and most expensive, but definately clean the butterfly, i took come carb cleaner, and sprayed it on there, rubbed it off with my fingers, and it helps a lot, it helps it breathe easier, and the engine since its a 91 will be a KA24DE a dual overhead cam 2.4L inline 4.

other than getting an ECU re tune, you can always take the tranny speed sensor out, but it will make your speedo not work, i wouldnt reccomend it, and i thought they topped out at around 109?

i really dont know about piggy backs, i know on www.tamparacing.com the nissan section talks a lot about the piggy back systems, i love living in tampa :) the guy makes the system to your specs, cheaper than JWT, but i really have no experience with them

Cams can be found at pdm.com. The dohc KA is basicly the same from 91-98 there are turbo kits for it. I believe in the ******** fourms there is a whole section for KA turbos.

this is correct but there are a few 91 240sx's with ka24e's in them because of an overstock by nissan(FRIGGIN RETARDS) just so you'll know

All you have to do is cut the third tranny wire. Nissan makes shit like this easy. Governors fucking frighten me.

I don't like the governers either but im not sure cutting the trans. sensor wires will always work I have heard other people say disconnect those to get around the limiter but I also read on the 240sx.org forum that some guy tried that, took his car to the track and almost got creamed when the limiter "unexpectedly" cut in while he was in third. This seems terribly dangerous if you need to accelerate and your car dies. I also read that there is a wire to the computer you can cut. This wire supposedly runs between the speedo and the computer. It isn't supposed to affect the operation of the speedo. It's just supposed to be "telling" the computer how fast your going. I apologize for telling you this and not being able to tell you the color of the wire or anything more specific about how to do what I said, also I have never tried this myself I only read about it on another forum a LOOOOONG time ago so I can't even guarantee that all this is true. wow that was alot of typing :givebeer:

Yeah, that's what the third wire is. It goes from the speedo to the ECU. I wouldn't cut the transmission sensor wires themselves... I think www.srswap.com has details about it in their wiring guide. I know I saw it somewhere...
