4.8, what budget turbo/WG/BOV to go with
Ok so I am doing a budget turbo 4.8 build. I have all the engine components etc.. now its time to get a turbo, wastegate, and blow off valve. I plan on running an ebay intercooler. this is a street car looking to get as much horsepower for the money. nothing too crazy. Question is, whats a good size turbo for the 4.8? should i go with a 44mm WG? i found a tial 50mm BOV for 150 on a local cragslist ad. good deal? also, anyone know of any reputable off brand turbos for around 300-600 dollar range? Im not looking to spend a ton on a turbo. any used turbo sites that i can check out?
thanks

Ran the ebay turbo all last year and not one problem...havent heard of one failure from the model I have. Funny thing is i took it off to sell...sold it to my buddy and was going to get a "name" brand...but ended up buying another one off ebay.....
Check out the new HotROD magizine..they did a junkyard 5.3, 01 zo6 cam, and ebay chinese turbo....made close to 600 hp....no intercooler....

Not that it help but I just finished my front mount turbo in a firebird 4.8 ls6 cam and a s475 t6 flange 1.32 ar I'm hoping it won't be ridiculously laggy but I do have a 2 step and it's a drag car. If the weather changes for the better I'll let you know how it works out

lots of guys running the small 475 with 83mm turbine and 1.10 a/r on 5.3s and it works about perfect. Most say its a bit small for a 6.0L motor and from my experience the 5.3/4.8 are pretty similar with the 4.8 having more compression. Like I said it will be a bit laggy but with a 3400+stall you would hardly notice, plus if you add a spool valve it would be absolutely perfect. Another thing is that you have alot of growing room with it if you ever step up your combo

Godspeed makes a decent 50mm BOV, all i did was re-seal it and it works, and sounds just like a Tial 50mm.
Heres a pic of it taken apart.
