Best engine performance upgrades !
Hello all wankelfreaks !
I have just picked up my FC turbo II cabriolet year 1990 in France, and have bought some very nice Arospeed Kai Racing Flight wheels and now I am looking for a little more power from that fantastic rotary
I am not looking for extreme powerupgrade, more like downpipe, midpipe and catback exhaust system, cold air induction kit, lightned flywheel, this setup would that demand ECU upgrade to give more fuel, maybe larger injectors ? if, wich ECU upgrade would be the best/easiest/plug and play ? about the modification items, which brands gives most value for mony here ? I know many use the Racing Beat exhaust system, but is there other/better/cheaper systems out there ? is a fuelcut defender a must with this upgrade items ? if, best one here ? I am allso thinking of a blow off valve, which do you think would be good/best for this upgrade ? I know proberly many people ask theese questions and many people have their own favorites, but if you could just give me a hint about what YOU think I would be very very happy !

I think with the modifications you listed above, it'd give you an excellent power increase.
The FCD will be neccesary with what you've named an upgraded fuel pump and secondaries wouldn't hurt either. I prefer the walbro pump and GSL-SE injectors. If you wanted to go beyond the FCD and spend more, look into purchasing a Microtech or Haltech etc.
As for the exhaust components, it comes down to preference of styling, sound etc more or less. I use the corksport setup which is a bit more inexpensive then RB.
And as for bov, this is also more of a preference matter but I think the HKS SSQV is one of the better designed units out there.

Here's the basics:
1: Full exhaust. Racing Beat makes a great one. Mine is custom made 2.5" all the way back with 2 Magnaflow mufflers.
2: Turbo inlet duct...rip that crappy airbox out of there and make a TID for it.
3: Port the wastegate. The stock turbo has a very restrictive WG and will boost creep due to the exhaust and intake thus blowing your engine...take it off and port it to about 35mm or more and install a bigger flapper. This will prevent boost creep and keept he engine in one piece.
You can stop here, or if you want to turn up the boost read on...
4: Fuel pump...more fuel to go with more air of course
5: Bigger injectors...you can just get a set of 720cc secondaries, or go for 720's all around if you plan on big power
6: S-AFC...you have to be able to control all that fuel
7: FCD...prevents fuel cut at higher boost levels. If you want to run more than 8 PSI, you need one.
8: Boost controller...now you can actually bring the boost up safely. I wouldn't go over 11 PSI on the stock turbo.
At about 10 PSI you should be putting about 230 HP to the ground. The rest from here gets even more expensive...bigger turbos, FMIC, etc. Have fun.
