I've been doing a lot of research and I think I have a good idea of the answer but I thought I'd ask those that have "been there" ...

My lease is ending on my current car and I won't be leasing another. I'm very interested in buying a used S2000 and going turbo right off the bat (or close to it). My goals would be a medium sized turbo (GT3076R or there abouts), most likely T3 framed, and get 450-500whp on 100% E85 (abundant in my area).

I have emissions testing every other year - the test is a simple OBD2 scan - no visual, no sniffer. I don't mind going back to stock for emissions if it just means swapping injectors and maps. I would not want to have to do any serious disassembly.

The other goal is for the car to have nearly stock like driveability (idle quality). It will also retain air conditioning and all the factory options (cruise control, etc).

The reason I asked which model year is best is because in my research I found that 04/05 can do the Hondata RSX swap for factory like driveability.

How are the newer (07/08? and up?) cars that can do the flash tunes? Do they have the same capabilities of retaining a factory idle and accessories?

Any info is greatly appreciated

Easiest emissions is probably going to be an 06+ with Flash Pro. I daily'd my Flash Pro setup for 2 years and went through emissions testing without any problems. Do you ever plan on putting in anything other than E85? I ask because if you do then you will have to completely drain the tank, not to mention having a second tune. If you wanted to be able to run any content of E85 (which varies by season anyway) then you will want the AEM Series 2. With 06+ this should be emissions compliant (you keep OBDII) since it's a dual ecu setup.

Thanks for that info! Does the Flash Pro have the same features as the RSX/Hondata swap like no-lift shifting and 2-stage rev limit (launch control)?

I can pretty much run E85 all the time. I guess teh only time it wouldn't be good would be on long road trips.

From searching, it seems like there are a lot of quirks with the AEM setups.... temperature gauges and other things... is that the case with the 06+ ?

I've also searched and found that the ID1000 injectors that would give me the best idle would limit me to about 450whp on E85. I don't want to go to ID2000's if it means a stable idle under all conditions can't be met (and I'm willing to deal with the 450whp limit). If in the future I were to go to a higher horsepower setup, which EMS would be most recommended to control a set of 2000's and still be driveable? Can the Flashpro do that?

Flash Pro has most all the same features as K-Pro and will cost you about 1/3 as much.

If you have any chance of running regular gas, at a minimum you will need two tunes. You will have to fully drain the tank if you do go somewhere that doesn't have E85 around. Your mileage will suffer so this will be likely if you go any longer distance.

I have the AEM Series 2 now in my car and everything still works, even the cruise control. All the gauges are also fully functional.

ID1000s are your best bet for good driving characteristics, but if you plan on going higher power then you might get the 1300s instead. Flash Pro will still do the job but something like the AEM will have more features and better peripheral support (gauges). However if you do stay Hondata you can get their traction control which works really well.

gtx3076 or 3082, i cant remember which people like more..i think the gtx3082. and 06+ s2k

Thanks a million guys... I was set to buy an 04/05 but this makes it a lot easier (no valve cover/sensors to replace).

Are there any downsides to the 06+ like weaker transmissions, or unfavorable features (drive by wire?), etc? Limitations that the older cars may not have?

The only disadvantage is the returnless fuel system. You will want to convert to the return style like on previous years. DBW would only be an issue for ITBs but since you're going turbo this won't be a problem.

Drive by wire is surprisingly good. I had a 2005 S2000 for about a year and now have the 2006 with the DBW and I am very happy with it. I have a 2007 Si and a 2008 TSX and the DBW in those cars is nowhere near as good as the S2000. Return less fueling is the only big downfall...I gotta replace mine soon! Good luck!

I brief search for fuel return system conversion brought up the Science Of Speed retrofit kit (using mostly Factory parts)... wow.. if I were to do it right with the AEM and AFPR, it's $735 to convert. I guess there goes the savings of the Flashpro
