performance decisions. I need help!
Hi,
I just started my first rotary performance build. And I need some advice with fueling and turbo selection.
This engine is going to be a street/ autocross engine, so the power doesnt need to be stellar, but I would love to have the bragging rights to a 300+hp engine (wouldn't we all?). Anyways, I'm planning on using megasquirt as my ECU since the engine is a carburated 12a. Im going to street port all the intakes, and make the exhaust ports bigger for more flow. I currently have an old T3 turbo sitting in my garage collecting dust from a previous project, now I'm prity sure the T3 is way way way to small for the rotory. So which turbo would suit my needs? My friend told me to get a T3/T4 hybrid, but he is a honda guy (he has also been my friend since I was 5, so I let the whole honda thing slide...lol) so I dont know if he realizes the flow of the rotary engine. I was thinking of a T4, but I'm not sure if that will be good for the street. Im also puting together a cheep fuel injectoon system using junkyard parts and alot of elbow greese. I just bought four 460 cc injectors from a fellow rotary guy, and I was wondering what junkyard available injectors I should add to my 2nd bank of injectors to make the flow I need? I could spend a bunch of money and buy a few 1600cc inectors, but I like taking other peoples junk and making it my treasure.
Any help would be greatly apreciated and if you have any suggestions on what parts work for cheep, that would help out alot too.
thanks
Mark

thanks for the info.
I just tore apart the 12a and found the rotor housings to be badly flaked, so I've decided to go with a jdm Turbo II 13b instead (way cheeper). Those turbo specs will still work for the 13b I hope.
