Read, lots and lots. Then read some more, then if you still have any questions feel free to ask us. These types of questions are really common and with a little bit of searching/reading you can answer them yourself. Its much more gratifying than having someone spoon feed you the answers.

Read the top two stickys on this page, that will answer the majority of your questions.

besides knowing engine and turbo setups, and the search button isnt always gonna help and being rude about it wont help the forums. you basically have your power goals in mind, so look at what kind of setup. do you want acceleration or top end power, the T2 family is great for daily power and on the cheaper side of complete setup. You can pretty much source everything on ebay or from other NICO users. But read up on installs and necessary parts before starting cuz you dont wanna get half way thru and forget that oil restrictor and blow it up. have fun.

For my personal goals, I only want 300 MAX, so I decided to go with a Big T28 (t25 upgraded to a "Big T28"). I also prefer acceleration + street/dd setup (which also happens to be cheaper).

I think a T3 would be a huge overkill if you only want 250whp max.

Please point out the rudeness. This guy obviously is new, and the best advice you can give someone is to read the stickies at the top of the page. No one even told him to search dude, give me a break.

Anyway, the t2 flanged turbos will choke a ka's top end. I have a t3/t4 50 trim .63 ar, and i cant see EVER wanting a smaller turbo. I start to see boost right before 2000 rpms, by 2500 im at 7-8, and by 2800-29 im at my full boost for now, which is 12 psi. If you want better response than that, go with a .48 ar housing and you will pretty much have the instant boost of a t2 flanged turbo with the ability to push 400 hp out of it.

The thing is, sure, you can get a t2 flanged turbo and ride around town in boost pretty much all the time. However, this sucks IMO for this main reason. In boost, your fuel econ is going to go way down which is NOT what you want for a daily driven car. Sure its fun for a while, until your paying 4.00 at the pump this summer and getting 15-18 MPG from a 4 cyl. It is NOT cheaper to run a t2 setup at all, thats a load of crap. You can get a super 60 or a small t3 used for the same price as a used SR t25. The manifolds range from cheap to expensive, for ANY turbo size. --- Basically, what im saying is for a daily driven car, you want the ability to stay out of boost. With a t2 flanged turbo, especially a t25, this ranges from really difficult to impossible.

Also, saying you have a power goal of 250 is fine. However, what happens when you get a little extra cash and want to go bigger? Your stuck with an undersized turbo, and a manifold you cant use. Your going to spend a lot more money in the long run because you went t2 flanged. 90 percent of people who are turbo enthusiasts will eventually want to upgrade, so why would you shoot yourself in the foot over the long run for virtually no good reason.

For someone that says we're rude for not spoon feeding this guy, you did the opposite and gave him incomplete if not bad info. The stuff on eBay needs to be scrutinized especially the T2 series turbo's since 90% are going to be cheap knock offs.

Then you mention oil restrictor, like he knows what size to get. Not to mention that Garret themselves say the oil restrictor is the last resort to be considered if you have oil seeping past the aft seal.

You piggy back with the bad info, a T3 is nowhere near overkill and to say so is an out right lie. You go ahead and dump $650 just to have a turbo upgraded.

Bottom line here guys, either take the time to completely educate someone the right way, or reply like we did. By reading the FAQ that I put together and the thread I made about boosting a stock KA there is more then enough info provided to give even the youngest novice a head start. So I'm not being rude...I'm simply pointing to the info that I already took the time to provide in the first place.

I'm all about helping people out, always have been. But reading up yourself is the best way to learn.

#1) I wasn't agreeing with you both being rude.

#2) MY T2x setup DOES happen to be on the cheaper side vs. T3 setup. The T3 route I would have went would have been a lot more expensive, but unnecessary for my goals...my goals. #3) I pointed out MY personal out take. I never told him to get a t25/t28.

He should evaluate his situation, resources, funds, goals, and come up with a setup. I never once said "you should get xyz". I was merely giving him ideas (i.e. options). I don't see how an "opinion" is wrong.

There's no reason to get so worked up....wow.

EDIT: 480sx: serious question here, not being an *** - if on the T3 you see full boost (12 psi) @ 3,000 rpms, wouldn't the T3 still be "in boost pretty much all the time"?

Yes, your in boost all the time from 2000 rpms up, with 100 percent throttle. With light throttle, the kind i try to do to maximize fuel econ, you dont hit boost at all. However, if you feel like stomping on it at 3000 rpms you pretty much get hit with 12 psi of boost within a few moments.

[Tx-Sx-FS]

ya the whole T2 flange is always in boost in BS, i drive my KAT all day and never get into boost unless i want to...and the ebay stuff, i purchases every item on my car from ebay and havent had a problem yet, so to everyone there own.

[WDRacing]

You said that if you want 250 that a T3 is WAY over kill...it is not. That isn't an opinion you stated. You were stating it as fact. Which is incorrect.

My main point is simple and I'm not getting worked up. When you spread information, you need to make sure it is as correct as possible. Hence our suggestions about researching, at which time he can come up with his own conclusions and determine what his goals will be.

"I think a T3 would be a huge overkill if you only want 250whp max."

Sure, will do.

[nissan2787]

wow guys im very sorry for the troubles but i will now use the search button and thanks alot for the info that you guys have already given me. i might go with a top mount t3t4 lol well i am new to this forum and someday i hope to have alot of usefull post without being a thread whore!

[WDRacing]

It's no trouble man, just a couple guys discussing a difference of opinion.

If you read through the top two stickies you should be well on your way. I only suggest lots of reaearch because this is something you only want to do once. With the proper parts you can attain your current goals as well as have room to grow.

Boost is like heroin, once you start you're just going to want more and more.

MMMMMMMM boost is good.Welcome to Nico! My t25 set up is fun, and I have no problem staying out of boost. But I am building an engine for a t3/4 set up. IMHO I think a t25 is a great turbo for a stock , daily driven KA. It is super responsive and will spank a lot of cars on the road. But like WD said, it is an addiction that is impossible to overcome, and you will want more. For price and fun, a t25 is hard to beat. I you shop smart, you can have a turbo set up for a few hundred bucks. A good t3/4 set up will cost you a bit more, but you will have a lot more potential.But in the end , it's your ride and your wallet.Good luck, and happy turboing.

Eh, i should stop talking out of my ***...

Just figured that it would be a huge pita to stay out of boost with a T2.. I have to stay pretty light footed on my t3/t4, so i thought a smaller turbo would be impossible to keep out of boost. I guess the t3.t4 is pretty small too.
