My stock twins are starting to blow some oil, I always figured on going single when I had to make a change. My setup is:
* RX7 Store Street Port Motor with Rotary Aviation seals - approx. 5k miles
* Currently setup non-sequential
* Stock fuel rail, new fuel pulsation value 550 primaries - 1300 secondary
* Upgraded Nippondenso fuel pump: Off of Jason's car don't know specs?
* Twin-power
* aluminum AST
* CoolingMist 2 stage water injection set at 5 and 12 psi
* Air pump and cat removed
* Full 3'' exhaust with magnaflow mid and Racing beat catback
* PFC with hand held controller
* Greddy Profec B boost controller
* Upgraded plug wires
* New fuel filter
* Cooling fan mod
* M2 Medium SMIC from RX7 Store
* K&N intake

My goal is to have a smooth power ban somewhere between 350 and 375 rwhp with good torque #s and quick spooling. I am not a drag race kind of guy, but do love smooth and predictable power. I live in central Kansas where 91 octane is the best your money can buy (some 92.7 with E10 blend), thus the water injection. I would rather not depend on the water injection however. I will likely try to get Steve at Gothic to tune it for me as I understand he is good and I believe the closest qualified tuner to me. Thanks in advance for any responses.

 

You'll find a lot of good info if you search this section. This question has been asked many times, and you'll find for your power range there will be many options.

Anyone else? I have tried searching. You spend hours sorting through other post with people talking about who knows what or with different set ups, and oh ya, my favorite, lot of responses telling the person to search. Don't get me wrong, I understand nobody owes me an answer, but if anybody is willing who knows, it would be much appreciated.

 

GT35R will do what you're looking for with very fast spool. 500R will spool fast also if your motor is ported and will have more top end then the 35R. There are others but that's speaking from personal experience

 

Richard,
I have a GT35R with a .82 exhaust side that will spool fast and give you the Power your looking for. Give me a call as I have a few options that will work.

T04E 60trim .84a/r

 

The Apex'i RX6 turbo spools very fast, and will definately make the power your looking for. Just make sure you get a turbo with fairly small turbine, if your only looking for 350-375 you don't need a big one and you'll get a much faster spool. Steve Kahn will be in Oklahoma May 27th for tuning. I will be there to get my car tuned along with another guy from here in KC. I'm not sure if you'll have everthing together by then but if you do...

 

T51r KAI and 10psi... LOL.

Yeah I agree.. stick with a GT35r or something similiar (T04Z, 500R, etc etc)

 

Thanks very much for taking the time to respond. It must get old answering the same questions over and over, but it sure is appreciated. I will start research each of the setups you guys suggested. Jason I will likely give you a call after I get my homework done.

 

Richard,

I whole-heartedly agree with Jason on that 35R. You'll be very happy with it. That is a smaller hot side version ( .82 vs 1.06 ) of the one most here are using. It's a Garrett ball-bearing turbo and will spool VERY quickly and very smoothly.

on a rotary with a 35R.. 1.06 or higher A/R with a a T4 flange
