Help selecting a turbo
I am getting ready to put together a turbo kit and I need some help selecting the proper sized turbo. I am building a car that is daily driven and will see occasional track time, but 90% of the time will be street driven. I am hoping to see full boost around 3,000 rpm, but I do not want it to run out of power before redline (if that is possible).

power goals? piping setup? Budget? People here have ran with anything from a t3/t4 to a T66. It all really depends on how much you are willing to spend.
I personally love my 35r/t4. Spool response is great and plenty of power.
Read some of the stickies or donate and search, that may help you make your decisions .

jcy98maxse ... Well, I have a budget for the whole project of $4,000 and I am looking to make in the 300 to 350whp range. I had actually looked at your setup and was thinking of using the same turbo as you. When do you reach full boost?

Im auto, T04B turbo, i start getting boost after 3k, full boost at around 3700ish or at 4k. I am very happy with how boost comes in. At first I hated how much lag i had. but that was because of being untuned and running too rich below 3k. now im tuned below 3k and above 3k. turbo spools rather quick now. for daily driving i think my setup is PERFECT. Driving like a sane human being you never see boost, once u slightly step on it, goes rite into boost.

That will do nicely on a 3 liter.. (assuming that's what you have..)
That's a very efficient compressor.. and teamed with a decently sized stage III T3 turbine, in a .63 A/R exhaust housing.. you should see 10psi by 3500rpm or so.. The 50 trim is nice.. holding at around 75-76% all the way to the 400hp level.

Yeah.. for what you're doing.. you don't need a 35R or anything crazy expensive.. That's a Garrett turbo, with a 360 degree thrust bearing.. it should last for years without any problems at the horsepower level that you're looking for.

cool guys i just learnt a bit for my car lol every one in my country wont help me like the businesses obvisouly dont want my money just wondering have u done anything to the motor to handle the new pressure like new pistons or custom planum?? or u just bolting it straight on?
i'v done the prep for the spacing like moved the battery to the boot and at the moment just got the pod filter attached pritty much to the start of the motor lol so got the room for the turbo just doing the ground work now really wondering if I better prep the mottor for the new poressure. thanks

Psi is irrelevant. You need to have a HP goal. 10psi on a t25 is quick, but 10 psi on a T66 is just stupid fast. Your looking at 220whp vs 400+ at the "same" psi. Decide on a HP goal and pick a turbo that will get that HP goal with a nice wide powerband.
For mild HP on a VQ look at a GT30.

In an earlier post I said that I was looking to make around 350whp. I was stating the 10psi for the guy who was asking me about what I was planning for upgrading engine internals. Do you think that a GT30 will work for those goals?

For anything 400whp or south of that.. go with a 50 trim T350 combo.. you won't be disappointed.. they can be had for less than 700.00 from Phoenixturbo.com

Would be a nice choice if you ever decide that you want more power. Other than that full-race tends to be a little cheaper than Phoenixturbo.com

If you don't know how to read a compressor map (they are kinda intimidating at first) learn how to. Use these as your bible for selecting a turbo. If you are wanting to run 10psi then find something that really opens up on making power in this area (of course leave some room above this area for when you want more:-). The turbo on my eclipse is a big 60-1 capable of 650hp and does not really enter the efficiency range until about 18-19 psi(i run 22psi) anything much under this level of boost feels the similar to my old 16g (that is like half the size). This may help you understand http://www.enginelogics.com/cmaps.html

OK, I realized that I forgot to mention that this turbo is going to be used for a rear mount turbo project I am planning. I am sorry. Will this affect my turbo choice? I was going to go with T3/T4OE 60 trim (the on Travis suggested).

Yea sorry about that streetz. At least you can say that you were the first. By the way, did that guy who emailed me about the custom sts kit help you at all with your setup? I remeber giving you his email, but didn't know if he gave you some advice. When I finally get around to doing this (working on getting my tranny built right now) I will probably have some questions for you. Is it ok to PM you with them?
