20b Ecu for Fd???
 
Yea does anyone know what kind of ecu should i be using for a 20b in a fd?? Plus where can I get the Ecu?

JoeD 04-12-02 09:34 PM

lemme guess....you have a stock FD and you want to to a 20B conversion, and think its a $2000-$3000 conversion...right??

BTW, you will need something along the lines of a MoTec to get the most out the 20B.

Jer 04-12-02 09:45 PM

My friend owns a autoshop so money isn't a problem but i need parts for the motor but i can't seem to find a ecu for it.

j9fd3s 04-12-02 11:57 PM

you can run a factory 20b ecu if you get ALL of the stock electrics. or you can use a haltech, motec, autronic, microtech, marelli, maybe even the new aem. there is no plug and play ecu/wiring harness for the car.

sorry if this sounds blunt, but if money isn't a problem, ditch your friend, his shop, and any curiousity of what parts you need for the 20b, and head over to http://www.pettitracing.com with $40k

Jer 04-13-02 04:52 AM

i can't ditch my friend because he is getting me the parts and motor. instead of spending 40k i only spent 15k all i need is the ecu/wiring. thanks for the ecu info but i just order a haltech(e6k) but i also heard that i need a ig5 for it too is that true?

Only if you want to run the split.

I would take into account who is going to do the tuning. The tuner should be comfortable and familiar with the ECU you have chosen.

Jer 04-13-02 06:54 PM

he knows how to do the tuning/installtion its just i have to find what kind of ecu/wiring i want, plus he is pretty busy and i can't bug him every day about my stuff when he has to handle the customers car first. im not saying that he is the perfect guy for the job but when your friend has a autoshop and its right next to your house its pretty convienant. Plus im just asking about the IG5 on what it does.

HyperRex 04-13-02 07:08 PM

hmmmm
 
You spent 15K...is that the total cost including the car? That sounds off.

Now, if you spent 15K the 20b + parts alone, you're probably on the right track.

The 40K you'd spend at Pettit does not include the price of the car. that's what they charge for the swap alone.

Jer 04-13-02 08:56 PM

15k for the motor and the parts car not counted

RETed 04-13-02 09:20 PM

$3000 20B
$2000 clutch
$2000 EMS
$1000 rad + cooling
$1500 IC
$2000 Turbo + manifold (unless you're going stock twins?)
$1000 Exhaust
$100 IC piping
$200 materials for mounting
$500 front anti-sway bar
$1000 Recalibrate suspension
$500 Ignition system
$1000 Fuel System
$3000 Rims and Tires
$1000 LSD
$400 Mazdspeed PPF

That's already broken $20k...
This factors ZERO into labor costs...you've got a pretty GOOD friend helping you...

Jer 04-13-02 09:37 PM

yea because all the parts we are getting are directly from japan..and its basicly pretty cheap over there

HyperRex 04-13-02 09:39 PM

sounds like a plan
 
Seems you know what you're doing then. Let us know what you decided to do.

RETed 04-13-02 09:42 PM

No it's not.
You're talking about an OS Giken twin-plate for an FD that retails over $2,000, cause this bitch converts the stock FD pull-type to a push-type clutch.

About the only other thing is the Mazdaspeed PPF unit.

Everything else does not have to come from Japan, but if it did, you're talking an extra 20% premium at LEAST.&nbsp That makes it a $25,000+ affair.

I call your bluff...I think this whole thread is a bunch of bullshit.&nbsp Care to offer proof of this so-called project?



-Ted

T88Rx7 04-13-02 10:14 PM

if you can get that done for 15k then ur friend would be a pretty rich and busy guy right now cuz there will be so many rx7 ready to put a 20b in there. and if i wasnt to sell my cars i would be the first there. correct me if im wrong.

The IG5 will allow you to control the split timing.

If your mechanic/friend knows how to tune a rotary then he probably has a good feel about which ECU to use (based upon what he is comfortable with and has worked with before). Like I said before...make sense?

I am sure that all of us would like to see some pics Jer. How about it?

I am at the early stages of figuring out the best way to convert an FD. How did you mount the engine?

black99 04-14-02 05:47 PM

To me the cheapest/easiest way to mount a 20b would be to use pettit's subframe/spindles. Or somehow make a subframe yourself. The pushing the motor back, recessing the firewall, and chopping down the PPF and driveshaft is alot of work, and you still end up with the shifter not in the stock position.

I am with RETed on this one, stuff in japan isn't that cheap at all, and you still have to pay shipping which most of the time makes it cheaper to buy parts out of the u.s.

I say if you guys know what you are doing then you can probably get it done for about 15k-20k with no overhead or labor costs. Not saying it will be perfect, but it'll run. One thing RETed didn't factor in is rebuild and porting of the engine. Not a must but you are investing this kind of money then you want to be safe and try avoid pulling the motor again and spending 5k that you hadn't planned before. And he didn't factor either using the pettit subframe or moving everything back for you either.

Unless you have a mechanic from japan that has done many 3 rotor conversions, knows his shit, and has a "cheap" way of doing things then I think it will be very costly.

Bitchn7 04-15-02 05:03 AM

I cant believe you Americans are willing to spend $20K+US on a 20B conversion. Thats NZ$50K.
Our Full rebuild of our 20B cost NZ$12K will full polishing, porting and all new seals throughout (oh and that included removal and instalation.
Now, Turbo and manifold NZ$6k, ECU, NZ$2.5K, Clutch NZ$1.5K, I/C NZ$1K, Radiator $1K,
now that's only NZ$24K, now I know there is labour and a few other bits and pieces, but not another NZ$26K worth.
You guys must go over board.
Exhaust, mate it up to what you already have.
Whats wrong with factory LSD?
Why add rims and tyres into the equation??
I guess you guys don't have "Kiwi injinuity" though do you.

My brothers boss (RX-7 Heaven, NZ) is about to put a 20B into his Bat. i will find out what that costs him. It wil be the first in NZ thats road legal that I know of. He already has one with an alloy 406 V8 and 6 speed in it.

AJC13B 04-15-02 05:16 AM

Bitchn - Soz mate. but an FD exhaust has trouble coping with a 13B ;p

He might be legit....give him the benefit for a while at least.... :D

That's about $5,300US.&nbsp The motors imported here range from anywhere from $2,000US to $4,000US.&nbsp A "rebuild kit" can only be bought from MazdaComp, which should easily break $1,000US for all brand new parts and gaskets.&nbsp That's already coming close to your quote - if these guys were in the U.S., the rebuild and porting would practically be free!&nbsp Is this something ANYBODY can pay for and buy?&nbsp There are very few shops that can rebuild these things in the U.S....


Now, Turbo and manifold NZ$6k, ECU, NZ$2.5K,
Turbo and manifold for about $2,700US - what brand, type, and model turbo are we talking about here?&nbsp Some plain-jane Garrett model?&nbsp Sure you can get a T76 for about $1,600US...that leaves $1,000US for the manifold.&nbsp ECU for $1,100US?&nbsp Microtech? :)


Clutch NZ$1.5K,
What clutch can handle over 500lb/ft of torque for $700US?


I/C NZ$1K,
Intercooler for $450US?&nbsp You can barely buy a CORE for that much!


Radiator $1K,
now that's only NZ$24K, now I know there is labour and a few other bits and pieces, but not another NZ$26K worth.

You're missing the custom engine cradle, ignition components (Microtech runs it's own coils?), piping for IC and exhaust, the upgrade fuel system (and fuel injectors), and serious fabrication for relocating the steering and front anti-sway bars - that's a serious amount of work to be calling "bits and pieces"...


You guys must go over board.
Exhaust, mate it up to what you already have.
Whats wrong with factory LSD?

Boy, guess you've never built one of these things.&nbsp Sure, you CAN use the stock exhaust, STOCK fuel system, STOCK tires and wheels, STOCK LSD, etc., but you'll end up with a very limited vehicle with a very restricted powerplant.

All the torque is going to spin anything less than 275 wide tires.&nbsp You gonna recommend we keep off the gas pedal now?&nbsp The stock LSD breaks with anything over 400lb/ft of torque going through it - that makes it a MUST-CHANGE item in my book, if you're going to even "mildly" modify the 20B.&nbsp The stock fuel injectors barely support over 300hp, you gonna keep off the boost too?&nbsp You're assuming a lot of fabrication that's gonna be FREE - boy, your shop is going to love you for assuming that much - do you OWN the shop or something?

I'd say you're seriously underestimating the cost to build one of these things.&nbsp I tell you what - you build me a an FD with a 20B swap into it, running, putting down at least 500hp for $10,600US, and I'll buy it from you + the cost of the car itself.&nbsp Here I am busting my balls, trying to do this conversion for under $20,000US, and you can cut that in HALF!&nbsp Boy, that's a bargain!

Oops, current exchange rate is 2.28 for NZ to US...

AJC13B 04-15-02 06:17 PM

Ted - If anything in Australia, we do get cheap turbos. You can pick up a turbo capable of flowing close to 800hp for under $2000AUD. Granted its not roller bearing, but it makes more than enough power for a triple :D

Jer 04-15-02 07:00 PM

ok first off all i don't know why some of you guys are acting like dicks when i asked for a simple question, i thank you for the others for answering my question. second the motor isn't even in the car yet so how am i gonna prove, i have know digital camera unless you want to send me some money to go buy one just to show you and when i said this is my friend of course he is gonna hook me up with the best he can do he has a webpage for his store but its not finish and i don't know if i can even post it up because its not my decision. if you guys are hardcore racers and live in so cal or near Orange county you should all know Speed Image from along time ago that is my friend his new shop is name "Jer" you can say he is pretty much the O.G. of import racers. since some one already answered my question this is my last post . thank You

T88Rx7 04-15-02 08:10 PM

all i can say is try to send some pics of how the prject is going
