Fujita Engineering (FEED)
Last night I read the lastest issue of Option magazine (JDM). It had a nice 10 or so pages on the RX-8. One article was on the work that FEED is doing on the Renesis. They figure that the 6PI variable intake is good, but that side port exhaust sucks... good for mazda to make the car clean, but bad for ultimate performance. Their idea is a hybrid engine. They are taking the front, intermediate and rear housing, plus rotors from the Renesis and peripherial port exhaust rotor housing (I am not sure from which... custom or from 13B-REW). They've only just gotten all the parts and assembled it so no telling what it will do, but they expect some loss of low-end torque, but to pickup 30hp or so.
Just thought it was an interesting idea that people might want to discuss...

Taka.... yep that's it... with the sketch of the RX-8 on the front.
There is also an article from the RE Amemiya team on ECU tuning. They've partially cracked the ECU and have been doing fuel and timing maps, limiter cut (speed limiter I believe) and SDAIS control as well. They want to get down to everything like electronic throttle control, traction control and such. There's a pic of the maps and data dump (looks like the one in the "cracking the ecu" thread) in the article as well.

Kinda funny... comments are all about the magazine itself and where to get it. None are about the actual thread topic... using peripherial exhaust ports on the Renesis...

If you mean high compression as in the stock Renesis rotors... then yeah. Headers is something else being talked about... well needed too with this setup... the stock Renesis one isn't going to work. I only skimmed the article, but I don't recall having seen any talk of FI for it yet... maybe in the future. The engine hasn't even been tested yet (as they just got the parts and assembled it) so they are looking at getting it running and seeing what it'll do N/A. After that...
Yeah... zero overlap will be gone on this FEED engine, and low-end torque will be down further they say, but they are hoping for better gains from the mid-range on up.

Hmmm... i dont know if i would want to lose any more low-end torque. It'll be interesting to see what their and RE's results show.
The japanese tuners have seemed to be very quiet, but its pretty clear they are working hard and will be bringing the fire very soon.

It's cool what FEED is doing, but they are basically rebuilding the engine. That'll cost some $$$$. But I still want to see what they come up with. Should be pretty good.
The ECU cracking is something that needs to go down. After reading that thread about an article where a Mazda R+D team in (Australia I think), built a turbo 8 with 360+hp. What was even more interesting is that guys who built said it daily drivable. Relatively speaking, it obviously was easy if he had access to the ECU code (from article:Engine-management is handled by a tweaked standard computer without any piggybacking chips. ). I've got to find that thread.

Seen that RX-8... but did not get much secret out of it. I doubt it is run by cracked ECU ... since I know no one has cracked it yet!
I have doubt in their reablility. We had a National last October where this car made an appearance, but at the pit lane only. They did not run on the track at all.

^^ Uh RE Amemiya has basically cracked it. Other JDM shops that offer to tune your ECU probably have too. It's not impossible, it's just that most places don't want to invest the time and money into something that has such a small market.
