I would assume that since they haven't been made in a while that they have or are finding their way into younger more "performance-minded" people's hands. Just as over here the luxury Lexus SC300 is being modded more an more. I haven't seen anyone do a BP single turbo or anything close while still using an auto cosmo tranny. I've heard of people using t56's for bigger mods.

But people are doing mods to them and still using the auto tranny, and I don't think people raising the boost(to 16psi), installing exhaust, intercoolers, etc(basically "modding" the cars) is anything out of the norm.

I've certainly seen a few 3 rotor Cosmo that have been modded. And I found one with the mods I listed above(more boost, exhaust, ecu, intercooler upgrade) still using an auto.

 

RETed, i will tell you know, if you can't egt a front cut for under $5000US, you are being ripped off.
I bought an entire JC Cosmo for $4500NZ, thats not even $2500US!, Well actually I bought two Cosmos. The one we use on the street as our daily driver cost us $5000NZ with a broken apex seal. The Cosmo I mension above, had a rebuilt engine too, and yes it was a 20B!
Oh, I also have a spare 20B JC ECU and AFM here too and know of a few others with them too. And, I can get a spare auto, and ours may be available soon too as we may put our 5 speed in the JC Soon. They are out there, you just need to know where to look.

No one modifiies JC because they are for 50 year old mens cars? I don't think so. RE Amemiya have modified ECU's to suit the 20B JC along with a modified auto to handle 500HP! There are numerous mods available in Japan for the JC Cosmo, and there are a couple of Cosmo owners clubs to support this too.

I congradulate Now for using your own determination in getting your car going, and on a budget too.

Remember, not everyone has money burnong holes in their pockets. I tell you, some of us kiwis over here have come up with some very unique stuff to get 3 rotors going without injection etc.
Check out the starlet in the feature cars section of this site www.badrotor.co.nz I can't remember but the rear drive 20B 323 may be there as well.

 

You're on. Oh wait, I won't sell it for 10k.... so nevermind.

I have nearly everything to put her together, and I'm still a couuple k under 10Gs... I'll keep you posted.

 

Now, was including the price of the car. And I have seen plenty COMPLETE front clips for $3500. Ill take that bet. Matter fact, lets make it interesting. Lets make a single turbo FC for under 10k? But when its done I doubt I would sell it

 

so i suppose re amemyia (i know i cant spell it) sells coilovers, fmic's, full exhaists, single turbo kits, for the 20b jc cosmo becasue???
and the cars at www.3rotor.com arent modified??

Sure...
Building a 700hp 20B FC will have no problems with someone banging on the firewall...
At least I know who not to consult on automotive structural integrity.

I am going to have to check into that, but i am almost 100% sure that the 4 inch long 2 inch wide ridge
over the trani that i moved up one inch will have
NO effect on strength.
if there is an effect i would hate to see what strength
is left in the 3rd gen car where they have been cutting
the fire wall and moving it back!

what are 20,000 reliable miles?? zero failures? or do we get a warranty?

mike

 

Oh, I could've told you that.&nbsp The sudden increase in 20B's in the U.S. hs supplier jacking the price up recently.&nbsp You'd be hard pressed to find one under $4,000; if ANYONE has a reliable source that prices them cheaper than this, I looking for several motor myself - please tell!&nbsp Can you shimp the front cut over to the U.S. for under $5kUS?&nbsp On average, I've heard of these things costing $5,000 - $7,000 on average shipped to your door!


The majority of engine importers in the U.S. have a very big problem securing the AFM and ECU's off of these things.&nbsp Don't shoot the messenger - I'm just relaying what I've experienced.


I have no use for automatic transmissions; I do all my conversions with FC or FD 5-speed transmissions (for "low" power applications).


I'm talking about Japan - are you talking about the same country?


Sure, I do too, but I dunno about "on a budget" at this point in time.&nbsp Maybe now can give us a quick run down on expenses to-date?


Speed takes money.
Performance takes money.
How fast do you want to go?
Unfortunately, I don't build these things to produce anything less than 500hp; you can easily do that with a 13B for a lot less money.&nbsp The 20B options is, IMO, for those looking for beyond 500hp with totally reliability.


-Ted

 

Hmmm...and you're going to assume they are being sold and install just because R.E. Amemiya has them available?&nbsp Come on Mike, I know you're better than that.&nbsp I believe there are only 2 or 3 "mainstream" rotary shops that offer products for the Cosmo (20B JC3S) - that should give you an idea of the demand for these products?



-Ted

 

20,000 miles as in daily driver - what you would normally do with our vehicles.&nbsp An occasional track day, here and there..."street racing" up to triple digit speeds...ability to go "cross-country" with very few problems (i.e. can you guys make it down to Vegas and back with very little fuss?).&nbsp Do you want detailed terms?&nbsp I guess what it comes down to is that no "major" component failure - wear&tear items are game, i.e. brake pads, air filters, oil filters, spark plugs, fluids, thermostats, tires, even clutches; items like radiators, brake calipers, oil coolers, transmission, rear diff, any drivetrain are not.

reted> the 20b cosmo has a large following in japan and
there are lots of people over in japan who add
performance parts etc. there are a couple cosmos
running around japan with the stock computer and
manual trani's making 16lbs of boost. the R.E. Amemiya
moded computer allows you to run either 9lbs or 16lbs
with the flip of a switch on the fly!
by no means are the cosmos getting modded as widely
as say the 3rd gens are in america, but to say that it isnt
going on is not correct.

matt

ps. the cost of my project is higher than it would have
been if I would have looked around for a cheeper clip,
but again I have heard that some of those cheap clips,,
are cheep for a reason! there are cosmo's getting cut up
because the motors have died and were not worth
fixing, I know my clip was cut up because of a accident,
and was in good running order.

 

Ever since I was totally raped by a JC Cosmo when driving in a workmate's MY01 WRX STi I have had a fair bit of respect for those cars. People DO modify them, and they go pretty well too

My question for all the people who have bought front-cuts / whole cars is this:
Who actually has an AFM sensed ECU? I've been digging through all my photos of front cuts and they are all MAP sensed. As well as this NOW's car is MAP sensed . So WTF is everybody talking about? No wonder they have trouble getting the AFM's. Is it because they dont exist?

Bitchn7: Can you check your JC?

-pete

 

There are two different "versions" of the JC3S 20B-REW engine.&nbsp The earlier "Series I" versionis more common, and this indeed uses an airflow meter.

The "Series II" engine is a lot harder to find, and it rumored (I haven't seen one myself) to be MAP-based engine load ECU system.



-Ted

 

but now's motor is clearly a series 1??

 

Yes, the give-away is the silver upper intake manifold.
The Series II 20B's have black coated upper intake manifolds.

The best "peek" I've seen is in this movie...

I love that video !!

 

I am not sure if Mazda changed the set up some where but I was lead to beleive that all 20B Cosmo's were AFM, the 13B modle are MAP sensed though.

RETed, I just mensioned the Auto thing because I thought you asked Now where he would get a spare one if it died. I can understand why anyone wouldn't use the auto. Thats why we are goiong to put the manual in our 20B JC.

Normally only the engines get shipped to NZ, but there are complete clips around now and then. We bought our one as a non registerable complete car for $4500.
And the complete (with broken seal) road legal car for $5000, and its been in NZ since new. I saw it for sale in 1991 for $125000NZ! kinda strange realy, I liked the car back then but new nothing about them, now I own that very car, and it was the first JC Cosmo I had ever seen.

the reason not many are seen to be modified is only 9000 were ever made, that small numbers realy.

 

Why would the 50 year old executive want a fragile car? It would have to be overbuilt for stock power levels. Are you saying the transmission can't even handle stock power levels?

Also, just because the car is built for a demographic doesn't mean nobody else buys them. Nobody buys the car for the 3-rotor engine and builds them up? I find that hard to believe.

 

Name something Mazda has designed that is "overbuilt"...
The stock 5-speed manual FC3S/FD3S transmission (which has it's roots back to the RX-3 SP transmission) is actually one of the exceptions.


The car is relatively "rare" - I've heard the number 9,000 units thrown around.&nbsp Ever try and price a 20B swap in Japan?&nbsp You think our $20kUS figure is ridiculous...Japan shops charge TWICE that amount.&nbsp I know the Japan consumer has a little more money, but NOT that much money!&nbsp Let me tell you about demographics...the people that have money live in urban areas.&nbsp Urban areas have very little or no garage space - you have to even PROVE you have a reserved garage space to OWN a vehicle.&nbsp These guys do not tinker with their cars; they take it down to the local specialty shop to drop BIG money on mods.&nbsp The folks out in the "country" have more space - these folks actually have the space and the time to do such an ambitious project.&nbsp Now, do they have the money?&nbsp I doubt it - it's a catch-22 situation...&nbsp Don't even try and apply YOUR demographic stereotypes in Japan; that just does not work.



-Ted

 

How many modified GSL-SE's are there?

There are 9000 20B Cosmos made? That's three times as many GSL-SE's, no? Yet it seems like everyone and their brother has at least one GSL-SE.

I'm sure quite a few that have filtered down into NZ and Australia have fallen in the hands of people who are not satisfied with stock performance

 

sorry, double post syndrome.

 

yes quite a few JC's are starting to make it to NZ, well no more will though thanks to a change in NZ import car laws.
What a few of us find funny though, is that a lot of yong guys here buying them are getting the 13B model. There are two here I know of with 5 speeds in them and one of them has a single tubo, FMIC, repaint etc (hopefully have a pic to attach, its pale blue).
I can't understand, to me the whole concept of owning a JC is the 20B engine, but being unique is also a part.

I wouldn't say there are too many JC's on the roads around the world jusdging by the number of 20B engines around without a JC holding them off the ground. I have seen 12 in one ws here in NZ, 17 were at another in OZ, on more than one occasioan, and thats just the start. Can't be many left to modify I think.
Here is a pic of Pac performance in OZ JC. Couldn't find a pic of ther NZ blue one.

 

change in NZ import car laws?
sounds like the government there is getting
like the dictatorship here in Canada,,, or should I say Kanada!
We cant even watch u.s. t.v. here, I am guessing that
its because it hasn't gone through the propaganda
machine first...
matt

 

Government has put a ban on pre '96 model cars being imported from Japan. safety issue they recon.

 

thats bs, wtf is different in 95 saftey wise?
and ted the r type transmission is actually first seen in the 1970 rx-2. the r100 has the even more unusual split case tranny. and if there are 9000 cosmo's that doesnt mean much there were only 13,000 and change fd's imported here, and probably even fewer t2's*
