so i popped my turbo tonight....
what i dont understand is why people buy these huge turbos and dont push them even close to the limit. most people with a big turbo kit are only hitting mid 400whp anyway unless they crack the engine open. if i can hit the same numbers on a smaller turbo for less than 1/2 the price, why not?
this is why not.. a larger turbo has a better effiiciency range a smaller creates alot of heat. If a turbo produces 50 max lbs per min and another produces max 75 max lbs per min and you push themboth to 400whp. which one will be safer to run in that range. BTW you will need a octane/ cooling adder to reach that 400whp mark with the ko4+or the bnr and if someone dont there a idiot.. Its creating to much heat. Also with a larger turbo you dont have to push the engine as much with boost!!
I can spend 1k on a exaust manand a turbo and itll be internally wastegated and itll come with oil lines and also a flange fo whatever downpipe i would be using!!! So spending the 1k on a bnr turbo to me isnt worth the little power you gain.

ask anyone running a gt2871 (essentially what the bnr is) and theyl tell you its worth it. i picked it up for 850bucks and all i need is a bov which i can get for 100.
also, me hitting 400whp on this turbo would do no more wear and tear than someone on a maxed out stocker. a maxed out stocker would probably do worse.
heres a question for you, what car would be faster from a roll? a gt28 powered car @400whp or a gt35 car@400whp?
Your awnser is this. ( Depends on the type of gt35, twin sctrol gtx series and ect. and if break boosting is there (Of course lol). ) The issue is not the fact its still a small turbo or even a large. it is the fact you are maxxing the turbo out ( stressing everything) ill post this link up from garretts site. for there gt2871 not the bnrs. The garretts turbo is max 475hp (Not whp)so prob 420-400 whp. So after i looked at the compressor map id say it would still be benificial to go with a larger turbo. And yes in fact you can find a turbo that will bolt straight up to the stock mani with a adapter and it will bolt up to the stock piping and down pipe will need a adapter. but itll still be under 1k or at 1k for all the parts.... I have my ways.. I understandwhat your saying. straight bolt on and it has the capabilities of creating good power. but its not safe powerfor the turbo and the max airflow...

I don't know what you guys are saying, but I do know Treadstone kit will bolt up to my current set up and I get a Precision turbo. I don't know if that's good or not?
I'm considering it though
***Edit***
Oh I just learned it's like BNR, I need a BOV and new oil/coolant lines

also an extra 60-80 whp for less than a grand is a great hp/dollar ratio.
The poweband on the gt28 is **** too.
considering the turbos map shows proof it it not being in the range of efficiency at 27lbs at a higher rpm yes its not efficient. it might be a upgrade but its a upgrade for someone who wants 400whp. ........ i can get tubos and ect cheap and no not ebay lol.....

Comparing new to new, Your way better off putting together your own turbo kit (purchasing a manifold, oil lines and such from seperate shops/vendors) Then buying that BNR thing for 1200 bucks.
If you do not want to get your hands dirty, Then yeah the BNR is cool.
If your someone with a hint of knowledge, putting together a Good turbo upgrade for a SS/TC can be had for under 2,000 dollars. (providing they already had bolt ons like a intercooler and such)
You bought yours used. So you got a discount on it. That ill agree with

the turbo alone (lets say a gt30) would be a little over a grand. they you need the following:
exhaust manifold
wastegate
BOV
charge pipes that will fit the turbo
intake that will fit
maf relocate (unless you recirc the BOV)
oil and water lines
custom downpipe
maybe an MBC
this all assuming you already have an aftermarket I/C n shyt.
i might be missing a few things as well.
after all that you will be pushing around 450whp on a decent tune on pump gas.
now, you can spend 1200 on the BNR, use all your stock stuff, and just get a BOV. so for less than 1500 bucks you can have 400whp on pump. you can close the gap between the turbos by throwing meth or E at it. you could throw meth or E at the bigger turbo but then you risk blowing your trans.

Just for arguments sake though, I doubt anyone would buy that little turbo it does have a bigger inducer than K04+ though.
All pointless, I don't have knowledge and will not be building my own kit. I'll be buying a kit from someone. ZZP or Treads kit
