RE: Turbos IIs and Power FC
Here is my question:
I'm planning to run about 400 hp (w/ the possibility of 500hp) on A Turbo II. So herein are my questions:
1) Obviously I know that the 89+ version of the Turbo IIs are better suited for more power. Is this power also attainable w/ the 87+ versions?
2) Will the stock ecu have to be modified to accompany these modifications as the FDs are?
3) This question is directed more towards Soul Assassin as well as others that may know. Regarding the Apexi Power FC...I was told that they had an application for the FC (maybe in Japan only), however, upon checking the Apexi website (both US and Japan)...there is no application for the FC shown. Can someone verify whether there is a Turbo II application? IF, there is a Turbo II application, does anyone know if the Power FC is applicable to all Turbo IIs (US versions)or maybe just the 89+ versions?
Thanks!

2. For 400hp, definately going to need an alternate ECU
3. There are Power FC's running around that have been tuned for the FC's (series 5's fromw hat I have seen) They are done by tuners in Japan, and I have never seen one operate in person. There was one for sale a few months back on the parts trader. Apex does not sell one made for the FC's. You could install a 13B-REW and use their regular Power FC

400hp is about the absolute limit for an FC3S turbo engine.
You end up cracking the tension bolt bosses in the front housing due to the sheer power produced.
A stand-alone ECU is HIGHLY recommended for power levels that high.  It can be done with the stock ECU, but you're severly limited by the stock airflow meter, whether it be the 1986-1988 Zenki "flapper door" or the 1989-1991 Kouki "sliding cone" air flow meters; most stand-alone units convert to MAP-based load measurement, which eliminates the previous mentioned restrictions.
You're need to "bulletproof" the engine internals - check out the Racing Beat catalog for all the goodies for this step.
After taking care of the engine, you need to nail down a good clutch system and an aftermarket (read:  KAAZ) LSD...
Someone ported the A'PEXi Power FC to ONLY the 1989-1991 Kouki models.  I think FEED or Panspeed did this?  You're still limited due to the airflow meter, so this is not something I would recommend...

Ok. From what you are saying...there are Power FCs out in Japan that are modified to work w/ the FCs. However, that does not guarantee that it will work w/ the US version...am I correct? Assuming that we had got ahold of a JDM and a US spec version Turbo II...does that mean that the ecus are swappable/compatible?

Regarding the limitation of the airflow meter, what do you mean? Is the limitation still there even though I acquired the Power FC?
I appreciate everyone's input by the way!

actually with the PFC used on the FC you do not use he AFM any more. you convert to a MAP sensor and the PFC comes with the equiptment needed for this. there is information available on it on Apex's japan site, but it is in a sub catagory at the bottom IIRC.
ive seen people make more than 400hp on stock un-doweled motors, though i cant tell you how long they held together. these motors were also ported. i am shooting for the lower 400 range also, and am still using a bone stock 89-91 motor. i know tony farkas made 375rwhp @ 12psi with a bone stock 89+ motor using 4x720cc injectors and an E6K.
at any rate, id go with the haltech over the PFC anyway. the only area where the PFC is better than the E6K that i can think of is the ease of installation, seeing as its plug and play.

From what i have read, Crispeed said you don't have to worry until you hit ~600RWHP+..
The reason people crack there rear housing is because of tunning... Maybe someone else can chime in... Crispeed???

well where should i begin--- power FC is made by AP enginering it si a complete plug and play computer the air flow meter does get yanked in favor of a map sensor even easier if you convert to a FD intake system,the new version are compatible with stateside FD commanders the old ones weren't. as for the 400hp limit i must disagree more like 600hp is the limit over here! lol! i am currnetly using zenki rotors with FD housings and a half bridgeport pushing 25 psi of boost with no problem expected life out of the motor is 30k
