I was just wondering if it would be more reliable and or make more power if I would stay with stock compression and run lower lbs. of boost with possibly a smaller/different turbo, rather than running more lbs. with vitaras and lower compression and having the turbo spool at a later rpm.. what would be more reliable and what would make more power and is it worth it to sacrifise some power for reliability? I would plan to run 17lbs with vitaras with a t3 .42compressor .48turbine with 8.7:1 compression, or if I got with stock compression I would probably run 10lbs with a t25

also; could these turbos provide that kind of boost?

I <U>want </U>and <U>hope</U> to make 275whp+ if anyone could suggest a better set up what would it be.. also I dont want to spend a fourtune on this, but still want to make some decent power

 

Those turbos are not what you want to achieve 275+ whp.

 

would a t3 .42compressor .48turbine at 25lbs compare to a t3/t04e 57 trim .60 .63 at 14lbs.?

 

that small t3 will max out real quick at 250 or so hp. if your going to build the motor go with a t3/to4e, if you want quicker spool and have the stock redline you might want to consider a .48 hot side. for example i will be running a t3/to4e 60/.48. on a d16y8; also that small t3 will die out uptop real fast.

 

So would I make more power with less boost on higher compression, or more boost on lower compression?

 

I dont want to spend a ton of money on the turbo.. thats why I was looking at the t3's.. I don think I could afford a GT30R, so what would you recomend for around $250-$300, or less...

also, I bought the block with no pistons or rods.. would I be better off going with vitara's and running more boost or couldnt they handle it, are they any better/worse that stock pistons as far as how much heat/boost they can take?

Edit: If I was to minorly build the block with Eagle or Tuner Toy rods, with vitara's and a block gaurd, could I use the bottom end to its full potential without major head work?

 

BUMP, need to know ASAP!! what about a t3 super 60, .48 turbine .60 cold side 60 trim around what rpm would that spool at, and can the internal wastegate be removed. is one with shaft play worth $115, I could get a rebuild kit for $80ish.. is that a good price?
