I don't care if I could get a billet setup for $600. Their quality is equivalent to ebay; this isn't an opinion of mine just a direct observation in person with more than one unit. You wanted advice, I'm giving it to you. If want AR advice I'll simply say go with something in the .8-.9 range.
My friend has reassured me those problems are "in the past" and they were "minor" problems, I'm just curious to what exactly those problems are... I know nothing about this brand besides the fact that they tout billet technology and are apparently the latest in turbo design. According to forementioned Honda guys. My buddy put 675 down on racegas with an 82 and he tells me he's never had any problems.. A google search yields little... Anything I find is indeed a giant pissing match and doesn't get into detail about WHAT exactly is so bad about them.. A link anybody?

I told my buddy to go ahead with the order but I'm honestly going to be calling him tomorrow and having a chat with him about possibly cancelling the order. I typed "precision turbo sucks" and got a million pages of people talking about exactly what I wrote. Lots of threads with lots of people posting about lots of friends with lots of fried turbos.. Seeing as I'll be fabbing a vband to go with my downpipe and I need to get this fkin build DONE already, I might be taking some people's advice in here. I have some other friends that I can get stuff for cheaper then online... Borg warner and Garett mostly..

Another important detail that you left out was if you were using AI? FMIC with piping length? Amount of boost you want to run? ALL of this plays a large role in turbo threshold and system efficiency.

On pump gas only, you are going to have to oversize slightly due to a boost limit. But with water injection you can undersize and run a bit more boost.

AI - Ball bearing T04E, .82 ar with preturbo water injection. This would be one zippy bastard at 20 psi. Should hit high 300's and spool your face off. http://www.atpturbo.com/mm5/merchant...egory_Code=GTB

Pump only - GT35R, T3, 1.06ar. Should see around 370-400whp on 15psi with a ported S5 block. I see 15psi by 3600rpm. Awesome street turbo. http://www.atpturbo.com/mm5/merchant...egory_Code=GRT

After re-reading, I missed the part where you said no meth....

Water is the essence of life... and your rotary would love it.

I'm happy you're seeing the light. Their wastegates fail ALL THE TIME, and I've seen the turbos out of the box with bearing issues. Let me know if you want to consult something else for your project. I have a little bit of experience with turbo setups

Alright, I have a guy offering me a Garett gt35r .82 for roughly 1200 shipped.. I know that these are supposed to be top shelf(although old technology) and alot of guys use them on the Fd... What I was wondering is if it would be the right choice for my setup now.. Anybody use this on a t2????

Currently running a front mount, the piping is 2.5 I believe.. Water is something I'll consider in the future as I'm looking to keep costs down(new engine to be paid for)... I won't be running ball bearing because I've heard they don't work well with rotary and I don't see the point of shelling out an extra 700 dollars for a bit faster a spool... As for what amount of boost I'm planning on running, whatever is within safe limits. If the tuner doesn't think it's safe, I won't be the one to say anything contrary... As a rough guess, I'd say about 15-17.
