Dave I think a lot of the ideas you are getting have been done. 2.3, Red, etc... What I think is improving on what you already do best. Make big power. But do it better.
I'd say figure out how to get the same amount of power your used to getting out of a 35R turbo but having it spool at least 1500 rpm sooner. Divided housing, T3/T4 turbo, stroked, diff CR?, mid range cams, e-85, stock sized valves, mivec head, etc...
Make 2009 the year you have dozens of customers going into the 9's but they all hit 30 psi at 4k not 5k. This seems to me to be the natural evolution.

Absolutely not going to use a TS T4, I've done enough testing on it at this point to not be impressed with it. We did testing on the black car last year, had a customers car here with a FR TS GT40 on a stroker etc. Not something I am impressed with.
I had a stock 2 liter on our dyno today, stock block, stock head. HKS272 cams, our cast manifold GT35r kit. In 4th gear the car made 20 psi at 4100 rpm, in 3rd gear at 4400 rpm.
Not to be rude but I do not care to debate the TS stuff either. I haven't been impressed with it enough to consider doing it.
I want this to be a high torque, extremely responsive daily driver above anything else. It's not going to make 600 whp and 600 ft lbs but I'd like to see something square like that for power. Ideally 500/500 on our dyno would be a completely bad *** combination and I think it is possible. I kind of have that in mind, on pump gas would be really nice and E85 does come from the pump

It is very hard to deny what a great fuel that is straight out of the pump. Its the cheapest most availible umm should I say it "Race Fuel" out here hehehehe
Yes, increasing the static compression ratio will also help with the torque. I may have something cooking for that too. We've done a lot of things that aren't talked about or advertised.
I say give CBRD/Blouch a call and try out there t3/t4 hybrids (33r for reference). I'm sure you will be very impressed with these turbo's. For suspension I would run something other than apexi N1's. Try something like Bilstein PSS9's or something along that path if this will be your DD.
Engine
BR 2.3 Stage 3
BRStage 3 head
BF CAMS (they can be tuned on the stock ecu if you have the proper headwork done)
Race Intercooler and Piping with battery
BR 3 inch exhaust with HFC and Bullet Muffler
Perrin Filter BR intake
FP Red
Shearer Exhaust Manifold ( I know Buschur likes shearer since 9sec9 is using one)
Wislon V2 IM
Buschur Ported throttle body
Megan Ported 02 housing a EPM dump if you decide the noise and pollution is okay
Buschur Igniton and 1000 or 1200 injectors
Suspension
you said you already have one
Brakes
GiroDisc front and rear slotted rotors
PF Race/Street Pads
Looks
Buschur CF Lip
JDM rear
20% tint all around (looks so good on white)

I sure do like all the input!
It seems most of the input so far is something other than a 2 liter, something other than 600+ whp, stock framed turbo, stock ECU, emmission legal, stock appearing type build. That's what I seem to be reading the most.
A few things that I can't do. I am starting from old cores, used blocks/heads. I do not have used complete engines here and have no desire to drop in an unknown quality used engine. As for knowing the limits of the stock engine, we all know that already. Emery from STM went 10.0's and the engine eventually failed and ruined a good block, $1800 down the drain for the block replacement. We've built many-many 400+ whp stock block/stock head stock framed turbos. Very few problems doing that. Eventually though the stock piston or rod is going to fail and once again cost you for that perfectly good block that gets ruined. The bottom line on the engine is, whatever goes in the car will be built, it's the only logical choice. If the car had the stock engine in it, I'd stick with it. In this case the engine and head will be built for sure. It's going to make for some nice pictures and such anyway.
Just wanted to clear up that one things on the engine/head build. I'm starting from nothing so building it is the only logical choice.
Also, we did the Time Attack thing already for 2 years and did pretty well at it with the "Magnum". I would like to use this car for autocross and road racing more so than drag racing.........but the biggest intention is just a kick *** street car with a/c, power windows and that is very quiet.
As for the 200 mph standing mile, that is one of my goals for this year with my RS. First for it to run 8's, then go to the mile with it.

I am glad that you continue to have a passion for doing new things with the old Evo 8 platform and make new projects.
Honestly, it shows that you just love the car.
For myself, I think I get enough Evo vibe from tuning all the customer's cars that pass through our shop every day. The vast majority of the customers we are doing now have stock frame turbos like the FP red which is my personal favorite and doing pump with meth injection. We have dozens of guys out there with those kind of set ups both with 100% stock motors and also drop in pistons, etc.
Personally, I am not give to give any input into what I think you should do as I am more interested to see what you come up with and I would encourage you to ignore all the suggestions here and just work your usual magic.
For 2009, I am hoping to see more of your customers running 9's on street cars - that was the thing that had the biggest impact on me this year.
I am the kind of crazy individual who would have zero interest in driving a slower evo if I had the Bad Bish to drive around in.
I am looking forward to seeing what you will come up with and also seeing the new car in action in August at the Shootout.

Read all 50 pages of it. Good info there on what each part contributes to the overall power . . .

Borg Warner/Garrett obviously do not know how to produce a turbocharger, if only they were as wise as some of our vendors here!

Trust me Borgwarner didnt build those diesel turbos they sell to run on Evos.. If they did i wouldnt have blown 4 of them to pieces in 1 weekend.. Nor would brent rau have 6 of them in his trailer to swap out between rounds..
Doesnt Brent Rau's car break lots of parts, I don't think there is anything on his car MADE for what he is using it for
