OK, i'll go ahead and say yea this is my frist build and I'm 18. So there will be a few question that you guys may look down on and laugh,lol. I know quite a bit but not all. I bought the "Shift 180" DVD, that shows a guy installing his first SR20DET and other components in a 240sx as a helper. Well, i'll get started on this.
1) Whats the weight of the stock SR20DET flywheel? I'm either looking at getting a light weight flywheel, or having the stock one resurfaced. I plan on using the car as a daily driver and auto crossing, road racing, don't really care much for drag but that might happen every now and then.
2) For suspension i'm looking at KYB AGX shock/struts, with Eibach Progressive springs. Pilot struts front and rear, adjustable tension rods, sway bars, and polyurethane bushings from Energy Suspension. Any other suggestions?
3) Brakes, why spend money on flashy brakes? I'm going to go with the Z32 brake swap for the front, and for the rear 240sx with Brembo OEM fit rotors front and back. Stainless brake lines front and rear. And for looks going to have the calipers powder coated and polish up the "Nissan". Will the rear calipers from the TT Z32 work on the 240sx? What would need to be done to have them work?
3) As far as performance goes with the SR, i'm still looking into it and researching. I'd like to see 350-400 hp to the wheels being reliable for daily. Enough to put Cobra Stangs in their place and try to keep up with Vipers,lol.
I'm open to all suggestions and any well advised help. Thanks for any help.

dude. 350-400 reliably for daily use from a 4 cyl. is ALOT!! you may get in to the high 270-300, get you into the 12's. suspention is good unless you want to get the tein/jic majic products = $$$. brakes are good, rear will fit, dont know what is required. there was a thing about it earlier, do a search. keep in mind a lighter flywheel will drop revs quickly.
1. dunno the weight but get a lightweight one if you have the cash. it's a lot easier to do now than later;)
2. that's most of it. maybe some RUCA's and camber plates.
3. you can make the rear Z32 brakes work but it take a bit of fabrication to get it all working. there's a writeup somewhere around here about it.
4. i have a friend locally that made 315rwhp/335tq and stayed side by side with a Z06 on a highway run. if you want a "reliable" 350-400rwhp then you're going to have to have the internals built and have the car tuned pretty well. but nothing's impossible, it's all money.

Well according to some reseach that i read up on, says that the stock bottom end can hold around 450. First though, I'm getting the car from someone who did the swap so its kinda has it umm minor stuff here and there. The guy said that it needs a clutch, and a radiator (hes currently running the motor with the KA radiator 
...tisk tisk...) so thats gonna be replaced by a Koyo unit with fans probally. He also said that down the road I might wanna take the wiring harness out and send it to SRSWAP.COM and have them redo it so that it will be properly done. Its going to be a project that I will look after and learn all before i mod. Just worried about it being reliable for point A to point B travel.Other then that shes gonna be my baby. I'm looking at motor internals right now. checking out some peoples setups to see what they have done. I know its ricer, but i'm looking at some magazines to see what those people go by. However I'm also looking into true nonshow stuff as well.

One VERY important thing in doing a build up is that you shouldn't trust one single source in determining what to do.
This is especially true when you're talking about information on the net. One topic often debated on is the "reliable" hp that the SR can take. The reason for this discussion stems from the definition of reliability. I personally enjoy exceptional reliability, and will NOT go past 300-350 level with stock internals (I wouldn't even change out the turbo w/o installing a metal head gasket).
Anything beyond that is possible, and can be done with a bigger turbo, cams, & some computer work, but I can't in good conscience advocate reliability. True, the SR is very reliable for being a 2 liter with an aluminum block, but is very suseptable to irrepairable damage when over-revved and/or over heated.
The fact that you want to learn before you start modding is a great attitude. Too many people are in the grand tourismo mode, and just want to slap parts on to make the car faster. That's not quite how it works (lol), so please do a lot of research before jumping into anything. Do a lot of reading from different sources, again, is very important. Calling up reputable shops about what should be done is a good way to gain knowledge also. Be sure that they're not trying to sell you parts that are not needed, though. . .
Good luck on your project

Thank you for your input. I have a few friends who have SR's and get their help when I can. However I'm a "do it yourselfer",lol. I've watched alot of forums and I'm also taking the common sense of "Build the car from the ground up". Thats why before I even worry about more performance, I'm looking at suspension, braking, and chassis bracing first. Well, I'll have to get a clutch and a radiator first just to keep the motor in good health and don't plan on really getting on it until i'mve gotten everything else into account.
Considering that I won't have money to throw in another SR if this one blows i'll be babing this one for a GOOD while,lol. I plan on doing things right and never cutting corners on my build. I don't care how many hours I've gotta work at work to pay for the correct, trusted parts. I don't know if thats a good attitude or not,lol. I'll keep updated for you guys and let you know how its coming.
I'm staying away from coilovers cause i know the car wont see enough track to get the $ value out of them. Thats why i'm only looking at the strut/shock and spring setup. With all the other goodies as well.

a LSd is a differential, yeah it would work but, i think you are going to need a custom drive shaft to make it fit and some othr things, not to sure what else you need to make it work, its in the site somewhere. you can use vlsd from an SC modle, or buy internals to make an lsd, or weld the spider gears in the differential, to make a make-shift lsd.
Ok i found this while look for some random lighting stuff for the 240sx. I think it looks kinda cool The changed the LED lights in the dash and the gauges to all red. Does anyone know how to do this or would this be the thing to take to a shop (like a stereo shop,etc) and have them do it? Might really look at this down the road.
