if you have any technical skills and can use logic , you should be able to do it youreself ,there is more than enough info on this forum anyways to help you convert it ,
as soon as my engine starts ( i hope next week ) i`ll start posting some pictures (i did everything step by step ) not that yours has to be like mine but just as a guide line ,

you cant even use the stock computer in an fd right ??,so why bother
just get a stand alone ,microtech,motech,haltech (wow lotsa tech) and get it over with

Now for my three-part attempt to restore order in this thread:
A: I was referring to a stock 20B Cosmo ECU, not a 13B, but thanks for the information.
B: I was thinking that it would be a good idea, for appraisal purposes, to say that a certified mechanic did the engine swap, and to have documentation to that effect, hence the request for labor.
C: I apologize for not further researching the issue using previous threads, as per RETed's suggestions.
There, we can now return to normal posting.

no worries, i say be a newb and ask questions (dont flame me people)... if i see q's that i know answers to i usually answer them or point people in the right direction. and actually the question you asked (about being able to use the 20b ecu gets different answers from different people). some will tell you that unpluging the auto tranny stuff will put the computer in "limp" mode which is bad. however, the majority of people that i have talked to (especially people out of this country, japan, australia, NZ) have said that theres no problem... so im going off of what they said unless i discover first hand that it doesnt work.
as per the insurance stuff... i think they have a special apraiser (at least AAA does) that either figures out a value for your car (not sure how they do this) or maybe they just let you give it a value and insure it for that.... its something that i need to look into as well cause id hate for something to happen to the car and have them tell me its only worth $5K in the blue book. that is probably the least of your worries if your considering doing a 20b swap though

The other way to do this swap is to use custom motor mounts and a custom oil pan. Custom motor mounts run about $250 (I have a set) and can be used to mount a two or three rotor Cosmo in an FD. For the oil pan, youre on your own MVA apparently has made one but I do not believe he is selling them outright.
For the aftermarket ECU, Microtech has a 20B version, the Haltech E11 works and a few of the Motecs work. The Microtech would probably be the easiest in terms of initial cost and they apparently have good starter maps for 20B setups.

sorry, ive been really busy this week jim so i didnt have a chance till now. ok i just got off hte phone w/ them... yes the modified spindles ARE included in the price... however they want your old ones back... you do NOT have to ship the old subframe back as they completely fabricate a new one. ill look to see if i can find pics of the spindles, but hopefully i answered your question.
i also learned a few things that i thought id share that will help in a 20b swap.... 1) the FD throttle body is larger than the 20b one so its best to use the FD TB. ill look into this a little more, or maybe someone can post if theyve done this. 2) pettit sells some intake piping for those too lazy or incompetent (me
) to make there own... i will probably try to make my own though. 3) Pettit sells a DP for the stock turbos for $299.... this i may buy or see if i can get one from alamorotary.com for cheaper. most of the parts for a 20b swap are readily available... thats why i chose a 20b over something like jim's v8..... well that and its just plain wrong to put a piston engine in an rx7 (just poking fun jim)... ill look for those pics of the spindles now

but the switch connected to the auto shifter tell the controller what gear its in right?
did you try unpluging the tranny controller to see if it put it in limp mode? either way, it doesnt matter cause i have all that crap... just trying to save room at the passengers feet

Thanks for the heads up, and thanks to everyone who is informative, not insulting. I guess I'll just have to get a 20B myself, to see if it's any good.

Ditto. I've been browsing this site forever trying to pickup info on this swap and it seems like more people are willing to discourage it then see someone do it. Seems kinda backwards...

or its a lot easier to make a nice neat paragraph on how to do it than to actually do it.

Let me just add...if you really want to be taken seriously, and not get flamed, you might consider changing your user name...

I understand that no RX7 comes with a 20B factory installe. What I was trying to say was that if you took an FD and installed a "stock", non-ported 20B in place of the 13B, and kept all the turbos, etc., it should, according to several rotary specialty shops, generate up to 550 HP. I based this guess on documentaion from Pettit Racing, and articles in Modified Magazine wherein an RX7 and RX8 had 20B's installed, generating up tp 950 HP. It seemed like a good candidate for the fastest RX7 out there.
Now, before the flame war commences, I'd like to say that I would like nothing more to be put in my place and corrected, because I'm ony looking for the best way to make my car fast. BUT PLEASE, correct me with information, or a useful thread to view, NOT by simply telling me I'm stupid , or that I smoke lots of crack.
