1998 240sx LS TT swap alright gentlemen started doing my swap last weekend and i have got this project in full swing. i have a couple newbie questions goin into this. mainly cause this will be my first turbo build and or TT build on a LS. I have read alot about speed density tuning and MAF tuning and leaning towards MAF tune it seems to be more user friendly as tuning may come. The main questions i have will be about the turbo setup its self. it being a front sump pan and a remote oil filter i will be running the oil feed line off the filter housing then to a T then the lines to the turbos. not sure if i would have to run a scavenge pump/system since i will have twin turbos. the turbos will be mounted higher than the oil pan so not sure if a scavenge system is something i will need i plan on making it street/strip car street cause i do not own a trailer to get it to a track lol.
i guess my main questions i have are gonna be
-the scavenge system: is it really needed? is it something i should look into?
-fuel pump/system: i will be running a walbro 400lph intank pump. would i need to upgrade from my factory steel lines? at least the fuel feed?
-waste gates/BOV: running 2 44mm tial rep's 7-12psi not sure if i should use a cheaper BOV or spend the extra cash for a TS race port? opinions welcome
pics to be posted soon once i figure out how to post them lol

If you have read alot on tuning then you wouldn't be considering MAF for a boosted LS. Alot of scaling to do.
I wouldn't cheap out on a BOV as you already spent money on good wastegates.

And some of the most recent progress. (last 2 weeks) got motor in monday and had to pull sub frame and notch it so motor and trans could come back to mount just right. (bought a CXracing front sump pan and said no need to modify subframe) pshh so much for that.

I'm using a setup from some company called mkt. they are pretty nice and good pricing too. Running a poly trans mount and factory 240 mounts. And I was looking into the tial BOV's might go that route to match the gates I got. And thank you this is my first conversion I've done at my house turned out a lot better than what I thought

Update- got the motor and Trans bolted in and all suspension tightened up and will be heading out to exhaust shop this week for turbo piping, and intercooler mounting. Here are some pictures of it ready to ship out.
If you wouldnt mind sharing contact info that would be appreciated. Just did a google search and couldnt find anything.
Looks really clean especially for being done at home. I was in the middle of a turbo LM7 (5.3) setup but due to a few life events I will need to stay NA for now and just collect parts. I purchased the On3 7876 and had 2.25 turbo plumbing setup into a single 2.5. A few v-bands and some flex sections and I was ready to rock and roll but she will have to wait till next year or so.
Not sure if you want to keep it a secret but what twins are you looking to run? Whats the final goal of the setup? Cant wait for more progress.

Also my engine a 5.3l bored to a 5.7l running -.30cc dish pistons(diamond), eagle h-beam rods, stock stroke, stock heads with upgraded springs and lifter. Running a voodoo cam wanna say 232/234 with a 112 LS. That's probably wrong. I don't remember right off hand
