Hey everyone. So this past January I finally talked my wife into letting me purchase a 1994 FD. it was more or less stock apart from exhaust, wheels and air filter. Well needless to say that with it having close to 180K when i got it she was not in the best condition mechanically due to the previous 18 yo owner . So I bought it with the intention of major upgrades in the no so distant future. Well.... Now the time has come. I've taken my engine out and it's sitting in the garage on the work bench. Now comes the tricky part. I've worked on rotary engines before, but i never had a chance to build one that was more for performance than street use, and that one was for a friend and mostly experimenting. That's not saying that I want to build some monster that i can't handle. But I am looking to get about 450- 475HP out of a large streetport running around 15 PSI as a street / track car. So I have a question that is probably going to sound stupid, but I still need an answer. Should I use 2mm apex seals or 3mm apex seals? Ceramic or steel, and anything else i should so while I have it out and at the engine builder?
Obviously there are a number of parts that i needed to look into, and I have a few on order and already have some , but here is the entire parts list
VMIC from Rotary Extreme,
ACT pro-lite flywheel
ACT HD XTSS clutch
Nippon Denso Injectors (850CC and 1300CC)
SARD 280 l/h fuel Pump,
APEX Power FC w/ Commander ( should be here before new years)
Rotary Extreme 34 Row Dual oil cooler kit
Fluidyne Race Radiator
Bönez 3" Stainless Steel Downpipe
Bönez 3" Stainless Steel Resonated Main Cat Pipe
GReddy Racing Ti Exhaust
A’PEXi Power Intake
RP Triple Race Pulley
GReddy Oil Catch Tank
Snow performance Stage 2 Boost Cooler
Tanabe Sustec Pro SS Coilover Kit
Now comes the hard part. I can't settle on a turbocharger that will give me good boost at lower RPM's with out sacraficing my high RPM power. I have been staring down the Trust TD07-25G turbo but I'm sure I'll lose some spool up time. I also have some minor parts like a BOV and wastegate that I've already installed. Suspension and brake upgrades are going in early next year.
I want this car to be fast, but well mannered. At some point i also plan on installing a FD3S Spec-F aero kit from Shine whenever my wife lets me get that, although I would love to get a full FEED kit. Anyway, Thanks for the advice especially on the seals and turbo options.

Look into the Garrett T04Z. It should come pretty close to meeting your goals without being overly laggy.
Seals are a different story. Everyone has their own reasons why they use a certain seal over the others. Check out the rotary performance and single turbo sections, theres plenty of info on different seals in there.
If this were my engine I would use 2mm steel Rotary Aviation seals with the newer design Atkins corner seals.
