Ok, as a rotary guy I'm gonna jump in here. To get 350-400 hp you had BETTER be running an aftermarket ECU (haltech or equivilant) or you WILL blow that motor so fast you won't know what happened.
yeah the motor i got/on its way is a 13B-RE (more intake ports better injectors) and it puts out more power stock than a stock 13B. and im planning on getting a aftermarket computer (wolf 2D) its about $1200 bucks but it will be money well spent. complete engine managment at the tip of my fingertips. everything on the motor is tunable with this thing. it has two programable maps (you can get more) which you can program however you want (ie. race mode/daily driving) and are available at the touch of a button instantly. pretty neat, you guys can check it out at www.wolfems.com. thats why i always give a range because its all depends on what i want to do with it but at the least its gunna have around 350 HP.
Ok, let me correct some misconceptions. The 13B-RE
W (that is what you mean, right?) from the 3rd gen DOES make more power, thanks to better turbos, better intake, and engine management to match. It does NOT have more ports, although the port size and shape is slightly different from the previous version. That is a sequential twin turbo motor- the stock turbo setup is very complex, so you will need to convert it to non-sequential. (the Wolf won't have a provision to control it!) Or you can convert it to a single turbo. ($$)
Only the 13B (non-turbo) and the new Renesis have more ports. A Renesis would be pricey currently, and you wouldn't gain anything by using that for your setup- although being able to approach 300 hp without turbos would be nice.
350hp is about the absolute limit on stock turbos. on the 13B-REW At that point you are getting out of their efficiency range.
Most rotary guys in the US use Haltech instead of Wolf, but both are good. Find a tuner that knows how to work with them before you buy. I'd make my selection based on who was going to tune it.
If you are REALLY adventurous there is a fuel injection unit called a "megasquirt." You build it yourself. So far the reviews are good, but it's a big project. It doesn't include igniton, you would need a distributor from an early car, and it would probably have to be "recurved."
For rotary motor help, go to the RX-7 Forum at

Good luck- this sounds like a REALLY fun project!

p.s. I'm "rx7_ragtop" on there. I haven't been on ANY forums in quite a while due to work...
