Just picked up a on3 70mm turbo kit. The turbo is bad but I was going to replace that anyway. All the welds look pretty good on the hot side as well as the cold side.
Im looking to get either a precision or turbonetics turbo or any other that is a good quality turbo. I have a T4 flange. I will not be running a ton of boost on this set up. The most boost I will be running is 10, just at the track, and 8 around town. these are my supporting mods on the car now:

stock block, pistons, rods, crank ( fresh build about 15k on it)
TFS stage 1 cam
TFS twisted wedge heads, 170's, 1.6 rockers (will have before the kit goes on)
gt40 intake
70mm TB
255 intank fuel pump
42lb injectors
SCT blow through maf

I want to run between 400-425 HP. I just want a reliable turbo set up and I know precision and turbonetics makes quality stuff im just not sure what size/model number I need.

other related questions I have:
-If you guys can think of any other supporting mods I need, please let me know.
-I know I need a catch can that can breathe, so wheres a pretty good one that wont break the bank or is this one of those things you gotta suck it up and get a good one?
-is it possiable to make your own oil return line to the oil pan or am I just better off buying a kit?
-will I need a in line fuel pump along with my 255 intank? if so, whats a good one, again trying no to break the bank?

This is my first turbo charged car so im a noob to it! Thanks guys

either the precision 6262 or 6266 would be more than enough. I personally would do the 6266 with a .81 turbine a/r. it would give you tons of power and torque down low

out of those I would go with the 6262 but its still pricey. im trying to stay around the 600-800 dollar range. Is that possible to do and still get a quality turbo?

only if you can find one used in good shape. even the turbonetics units are around $1000 brand new. its worth the extra $200 for a precision 6262. You can find some of the borg warner units a little cheaper and many people use those

Go with a 7065 precision turbo I know it's supports more power than your wanting but it gives you room to grow. On catch tank go to I think last page on the quick time thread and there is a pic of a customers car that we did. Used a vibrant performance catch tank.

any idea why the On3 turbo failed? I have not read many issues with them

was told the by the guy that i bought it from that he ran it for around an hour, wasnt getting enough oil pressure to it but took it on a cruise anyway and when he returned oil was comming out the exhaust. He wasnt to smart about it, didnt have a boost gauge, no chip no nothing. just put the small spring in it and trusted it. I picked up the kit for dirt cheap. I will be selling the 70mm on3 turbo he gave me with it. there is no shaft play on the cold side. a tad bit on the exhaust side. an new seal kit is like $35 from on3.

im not sure thats the right turbo for me. my cold section is 3in and that turbo has a 4in. just seems like that turbo is way to big for what im trying to do. I really dont need room to grow, if I decide I need to go faster, I will start a 351 motor build. thanks for the suggestion though. what do you guys sell with your entry level turbo kits for 5.0's?

For an external fuel pump you can pick up a Vortech T rex on here for cheap. I made my own drain line with two -10 push loc fittings and hose.[/QUOTE]

my question is, will I need the inline as well? I have a 255 in tank but dont want to be starving the engine at 10psi

That compressor housing doesn't discharged at 4" that is the standard turbo in our base kits
is your cold section piping 4" as well? I actually checked your kits out about 3 weeks ago but cant remember. They look to be pretty high quality though. I was going to look into maybe getting one but I got such a good deal on this on3 revised kit that I couldnt pass it up. Im just not really impressed with the quality of their turbos. Not from experience, but just from what I have researched. This is a newer model so it may be better but I still wanna go to a what I feel is a better style turbo.

Also, with my set up in mind from my OP, would it be ok to run a .58 A/R turbo? how would the engine react if there was a .58 A/R rather than a .68 A/R? would it spool faster with a .58? or should I just stick with the .68?

Found out I will not need a in line. Although its good back up its not a must. I also found out what the A/R number is.
