So I am literally at the end of my project. When I get money again, I am going to spend it on a turbo so I can finish my project. I need help deciding what turbo to use. I was going with a holset hx40 but it was too big, so I got rid of it. So I was doing some searching on this very forum and I came up with maybe using a Borg Warner S200 with the extended tip. Or I was gonna use a Garrett T04B 60trim and 1.15 hotside. It would be a S200 with a 50trim and a 1.15hotside. I'm shooting for a decent spool and like 350hp+. I have a street ported S4 TII, microtech LT8-S, walbro 255, 550cc primaries, 800cc secondaries, etc etc. I know 1.15 kinda big for the hotside so I was thinking of maybe changing it out to something smaller like a 1.00. Any suggestions on what turbo I should get. I was looking to spend like under 250bucks on a turbo, I know that is not alot for a turbo but I can get a good deal from a friend of mine. And I know these two turbos run around that much used. I know everyone is going to tell me to buy a gt35r or somthing like that but I can't afford one at the moment, I will definately upgrade later down the line for sure. But for know I'm open to suggestions.

any of the turbos you described are not going to be under 200 bucks. unless you find a ridiculous steal.

is this for a street car? DD? AutoX? it all makes a difference.
what boost levels are you wanting to run?

You DON'T have enough injector for any of the turbo's you picked or for the power your looking to make (ok, your very very close to border line). For 350 + RWHP look at getting a T04B V-trim, T04E 57 or 60 trim, T04B 60-1, T04B 62-1 or GT35/GT35R compressors. You'll need a T4 turbine in a P-Trim. For that power level a .81A/R non divided or .84 A/R divided turbine housing will suit your needs and spool pretty darn quick. If you want a little room to make more power (375~420) then a .96 A/R non divided or 1.00 A/R divided will up the power at the expense of spool time. Make sure you match non divided manifolds with non divided turbine housings and divided with divided. Compressor A/R values coincide with the compressor you choose. Most T04B's will have a .6 A/R with a 2.5~3" inlet and a 2" disscharge. The T04E's will come with a 3" inlet and a 2" disscharge in a .6 flavor also, but the diffusor will be slightly larger and flow more air then the T04B's. The T04B 60-1, 60-2, GT35, and GT35R will come with the T04S compressor housings with a 4" inlet and 2.5" disscharge and a .7 A/R value and flow gobs more then the previously mentioned. Also, your Walbro will become a problem after 400+ RWHP. You'll need a Denso or Bosch 044 fuel pump after that or run duel Walbros. lastley, your not going to find ANY turbo mentioned at all in this thread for less then $400 (and thats DIRT CHEAP {I used to be a Garrett dealer} new. You'd be lucky as hell to find one USED for less then $400.00. STAY THE HELL AWAY FROM THE EBAY TURBOS!!! Stick with Garrett, Turbonetics, Innovative, or any other Garrett varient even "Master Power" is ok. Stay away from "Tread Stone", "Master Power" knock offs, "SSAutoChrome" etc. Your gonig to need a fuel pressure regulator and a good tune not to mention a custome down pipe at least 3" or bigger along with at least a 3" exhaust for decent spool and power. You need to spend more time in the single turbo forum and get your learn on. You could make close to your power goals wiht a hybrid and save your self a butt load of money on manifolds, down pipes, waste gates etc (oh yeah, you'll need a waste gate too!!).

^That pretty much sums it up.

OP: How much money do you have to spend?

Why not a Holset HX35 ? Either way though, you don't have enough fuel. You need 1600cc injectors.

Give it up.

I can get a very good deal!!! Alright I will get larger injectors that is a given... I WILL NOT BE BUYING A KNOCKOFF!!! I've seen what happens to knockoff turbos.... Thank you "RacerXtreme7" for all that info. I really appreciate it. I am not going to 400 quite yet, maybe after a few months after I break in the motor. I was aware I would have to upgrade my fuel system.... Rigth now I am just going to try and make 350 (around there) and use it fror Daily driver, drift, and a lil drag I guess. I'm not a big auto cross fan.

go with the 1.00 hotside. you'll thank yourself later. once you start feeling that boost, your not going to want to stop. with the 1.00 you'll be able to turn that boost up without worries of chokin out the engine

i'd go with a 1.24 hotside... but you'll need at least 3" DP.
The T04E 57 is a great chioce.

dean23

1.24 is too big... he wants a quick spool...

.96 or .84 for quicker spool. go with .84 i think.

i hit full boost at 3k.. and i currently have a 2.5" cat back...

Once I get my exhaust cutout, I expect to see full boost at 2k or less.

What makes you think that the 550/800cc fuel injectors will get to 350bhp before the engine goes lean and blows up?

LOL... i maxed out my 750s in 1st 2nd and 3rd gear with the T04E

I'm stuck with the 800cc at least for the break in process of my engine cuz I am broke for a bit... I am having a friend of mine hold a set of 1000cc and 1600cc for me, for when I get money...
