I have a 1992 fd and i'm interested in any information that anyone has about the conversion. I'm starting the conversion in October. Cost is not an issue. Any specifics from personal experience would be appreciated. Thanks

Do a search and look at the 20B forum. I think you 'll find what you are looking for...

 

Cost is alway a problem ahhaha..
but since you are in japan..you can try one of the many tuners that do has done 20B conversions ..like re amemiya..

RE Amemiya has a racing 20B in the JGTC300 so they would be experienced in putting it in.

Or C Y sports ... they do some wild conversions too .

The problems with a 20B into a fd are, the mounting points(ie, sub frame) , the bumpsteering , also the transmission tunnell needs to hammered out . the gear shifter will be also moved back about 6 inchs ...etc

go the the https://www.rx7club.com/forum/forumd...?s=&forumid=95
many are running a 20b but mostly in the FC ...

 

SomeGuy, the tranny does not move, my 5speed will sit in it's stock location.

 

You are in Okinawa and you want to put a 20b in an FD? You want to pay someone to do it? Good f@cking luck!!!! There isn't a Japanese shop in Okinawa that has the knowledge to pull it off right. Yeah, they'll take your money and then shove your car in the back of their shop until you forget about it. If you want it done, you need to talk to Dragon. His name is Chris and he drives a yellow FD, I drive a black FD and we share a shop with a couple of other guys down in the Sunabe area, out gate 1 KAB. All of the fastest RX7's in Okinawa are out of our shop and the shop next door. If you've seen the white 20b FC, or the blue bridgeported FC they are out of the shop next door.

 

How did you deal with the extra inchs of the 20B in the front ? Did you have to move alot of things?

 

I am curious to see what shops like RE charge to do the conversion.

 

SomeGuy sg, can you post some pics of your car, its sounds pretty amazing... atleast thats what i get from your sig

 

IGY do you have any links to any pics of his conversions? Or yours? or their websites?

 

Dragon is actually in the process of doing his 20b into FD project. Sorry, no websites, and I haven't converted my car, I just tuned an FC that has been converted. I'm just working on a twin TO4S setup. By the way, FC's are waaaaayyyyyyy easier to convert.

If he ever gets his damn 20b out of the race car I will finish building the down pipes and wastegate piping, F@cker.

 

Hey, the Race car is my mock up to fab all the parts and make the kit so when I have it all done It'll drop right in my car.. I'm thinking it should be out of there in a few months or less..

 

Dragon, have test fitted your 20b in the car with your modified stock sub-fram yet? If so hows the fitment?

 

Keeping the tranny in the stock location is part of what creates the bumpsteer problem in the FD, because it forces the steering rack out of it stock location. You have to modify the spindles to realign the steering rack, once that's done no more bumpsteer.

 

ok and who sells modified spindles and for how much, if it's available somewhere?

also, does the modified pettit subframe leave the tranny at the same place, meaning you don't need to mess with the PPF and the driving shaft?

 

Pettit Subframe leaves the tranny in the same place. I'll have more pics up soon with the motor dropped in . My clutch is b eing shipped this week( Been waiting a long time for it).

 

You can get the subframe and spindles from Pettit for about $2200 with a core exchange

 

hmm well that's not to bad then, what about the sway bar issue, i guess this won't solve the problem heh?

 

With a 20B in a 3rd Gen a stock sway bar will not work, but again Pettit does sell a custom one to work with the 20B.

 

ok, i know i am being an *** but any idea how much he sells it?

 

Not sure call 954-563-6064. Ask Jeff he would know he does all sales for Pettit, you can just about call him anytime..........within reason.

 

cool, thanks a lot

 

If you didn't know Rx7Specialties accually makes the sub-fram Pettit uses. They sell it for 1,400 bucks. Call Adam 403-246-6980.

 

That's funny the two look nothing alike, but I guess they could, I'll call and ask Cameron @ Pettit

 

Well thats what I was told by Adam. Anyways its cheaper. Actualy the price is around $1600 and you don't have to pay taxes since they're in Canada.
