j here is a link not the one I was looking for though. http://www.hitman.hm/injectors.htm
I think the site with all the injector info is down right now.

setzep

yup, 550's all around for the 13B-RE.

SETZEP, I just checked out your exhaust, NICE work!! It looks f**cking awesome, I really like the rear bent down tip, looks so much like the dolphin tail exhaust from RE amemiya (which I came close to getting one time, and lust for it ever since). How much would you charge to make me a similar setup? Seriously, I would like to have a exhaust made for a turbo first gen, intsead of throwing some racing beat 2nd gen downpipe, and custom it from there. Let me know! Thanks

LTProject

yah setzep, when will you be taking orders? Looks great, keep up the good work!

setzep

lol, I got orders now?

But for me to make a full exhaust for anyones car I'd have to have the car on hand because you all are running different turbos than I. The DP would be different on your cars.

More fuel tech when using stock ecu with AIC.
Does anyone know why 2/3 of the FCD i had did not stop fuel cut and which one would you use if u did not have the haltech. Racing beat or HKS or ???????

kuhlrx7

The FCD's need to be for the 86-88 rx7 turbo. those ECU's had a lower setting for the fuel cut than the 89 + ECU. there are two basic styles; style 1 is a universal type design it has a dial or set screw to adjust for setting. style 2 is a pre set desgin no adjusting just plug it in. HKS is style 1, racing beat is style 2. the other option you have is to buy an upgrade chip from a chip tuner that has the fuel cut removed for your ecu. that is what I am doing plus adding an greddy e-manage to tune plus drive addional injectors. there are a lot of people pro and aginst the chip route. there is a club list site for japan that I had a friend ask the cosmo injector question he seemed to get two differant ansers some said 550cc in both spots, two differant styles, side feed in the primarys and top feed in the secondarys. the other ansers were the same injectors as the fd 550 in the primary and 850 in the secondary nothing about color though. I searched the archives on this club and also came up with the same ansers. also posted on this site

The green plug I think is for temperature, not 100% because mine has always had a custom fuel rail.

SetZep, I'm just running a simple sock Tll turbo, 89-91...... Come on, you know you want to build me a exhaust........ Think of the money.... Oh yeah, how thick is the tubing you used? if someone hasnt already asked.

setzep

It may be a simple T2 swap but still don't know where the turbo is located in the engine bay

I used mostly 16 gauge for the DP and MP but used some 18 gauge for the over the axle tube.

setzep

hmm could have sworn that it was ajc-13b that told me they were 550's all around, maybe not. But they are side fed primary and top fed secondary, I do know that much cause I just looked at them today

Rex4Life

I just realized my 84 cruise control actuator won't work with a TII engine (duh boost vs. vacuum). So looks like I need to move over the TII electric actuator and control unit. That or maybe I can reverse the control signals and use boost with the existing actuator.

Do any of you guys know if the speed sensor from the FB will be compatible with the FC unit? Other than that I don't see any problem using the FC cruise control.

Thanks

ok i FINALLY got my gsl-se to do my supention swap.(my turbofb is a 83 limited edition) I also pulled the fuel tank and the crossmember. So now im able to drop in a 13b(the factory way). I have ported my plates and im waiting on a good deal on some housings. then ill get the stuff and stack the motor. I drove down to Fl. to pick up my Microtech LT8 2 weeks ago and that has lit the fire under my but to get this thing rolling . i also have my sr5 turbo...but i need to send it off to BNR to get the stage 2 to4 upgrade and i also have my starion/conquest TSI FMIC.

I've been looking at all the diffrent "styles" of cooling people are running... some run a stock rad. some lean a 2nd gen rad in the nose. Im still up in the air about that ..... I DONT want to overheat this puppy. I have been thinking of just running the stock fan and shrould with a new Automatic "TALL" 84-85 gsl-se rad... so it should be 3 cores and tall... that with the fc oil cooler i hope will keep her cool.

setzep

You are sending the turbo to BNR? Send it as soon as possible, he has a lot of things that he has to do and sometimes it takes forever to get you stuff back from him. So if you don't want the turbo to be your hang up I'd send that sucker to him ASAP!

Most people use the stock FB rad, the way I see it is if AJC-13b can use the stock rad so can I I have the gsl-se one but some have switched to the shorter fat one so they can mount the oil cooler under it.

Cool thread guys...we get the same questions coming up on Ausrotary all the time, its about time we had a sticky. That cosmo conversion is coming along very nicely - great work!

OK, now a s4/5/cosmo 13BT conversion is relatively easy when you have the right parts and the right tactic, but lets look at something a little harder.

I wanna put a FD 13B-REW in my series 3 (1985 aussie model). This would at first glance appear to be no different to a cosmo conversion...but there is one big problem: a stock FD ECU uses a crank position trigger mounted on the front cover not a crank angle sensor which would normally fit inside a a 12A/13B front mount cover. I wanna use the FD ECU for legal reasons, plus the FD engine has the 850cc secondaries as mentioned, plus a better intake runner/plenum design.

What are your suggestions on tackling this?

I know a guy in the states did it - i read it on this forum and I've PM'd him, but how would you front mount the REW, or mount it otherwise in a 1st gen body. I reckon you could remount the crank triggers on a 12A cover if you were careful with your measurements and used the timing pin with a timing light to fine tune their placement.

Any thoughts?

J Oliver

I was under the asumption that the 13BRE Cosmo was a far superior motor to the 13BREW FD motor especially when it came to intake runner and plenum design, this is why I spent so much time getting one so whats what? Oh ya have we decided that the COSMO has four 550cc inj. or 550 and 850?

setzep

KYPREO- you pretty much spelled it out. Either have to mount the trigger wheel on a FB front cover or make new mounts to allow it to be bolted into the FB chassis.
As to the REW being better than the RE there is some debate on that subject. Internally the FD is better, RE has larger intake ports, REW has better exh sleeves, some say the RE intake manifold produces more torque, the RE has larger runners in the intake, REW has larger twin turbos and the list goes on I'm sure. But when it comes down to it I got the RE because it was a little over 1000 usd cheeper than the REW at the time.

J-Oliver- I guess the injector debate is still up in the air.

KYPREO

thanks guys....yeah it all seems pretty debatable.
The other reason i guess is the that using a stock ECU would be easier with an FD as it is manual already, and you don't have to worry about tricking the cosmo ECU into thinking there is an auto box there. I was under the impression that the FD runner design is better for low down torque and lag with better flowing runners, while the cosmo has the larger volume plenum which would be better once the boost has been turned up. I would add to the list of advantages that the CPS is slightly more accurate than the CAS, but its pretty academic in the end probably. Cost is an issue, but I'd be getting a front cut, so with the FD you have the advantage of a perfectly good 5 speed there to use.

The juries still out! They're both better than a 13BT though.

FYI, all 84/85 Radiators are the same, SE or not. They are also only two core (tall) versus the short 3 cores of the 81-82. I think 83 has the same as 84.

The only difference the "automatic" radiators have (from factory) are the two tubes for the auto tranny cooling.

All stock replacements have those tubes, whether you use them or not.

KYPREO

the 84/85 model in australia only got the tall one-core radiator - how bad is that!

Directfreak

iTrader: (2)

Pretty screwed up, but I am pretty sure it's a 2 row core.

Also, why do you want to handicap yourself by using an FD ECU? Or the Twins for that matter?

You're in the land of Haltech and Micro-Tech, use them to your advantage. The stock ECU's are only for stock cars and stock power levels.

KYPREO

ours were one row (around 18mm from memory) - got one sitting in the garage which I replaced with a series 1 three row.

The ECU/twin turbo choice is a thread in itself, but briefly for four reasons: (1) legality - can be engineered for street registration with less hastles with stock ECU and turbo setup; (2) my initial goal is only around 180rwkw and this is *well* within the limits of stock ECU/twin turbos, so the initial setup costs are lower; (3) when I do want to go faster, which everyone always does, there's nothing to stop me using the new Microtech LT8 series 6 plug-in, which utilises all the stock ECU closed loop, electronic OMP, etc, along with a bigger single turbo; (4) there are merits to the twin turbo for a street/circuit car.

setzep

Got a question.
So I want to get a new slave and master cylinder for my car. I have a 83 FB and a T2 trans. I understand that I need to get a slave cyl for the T2 trans and a master cyl for the FB chassis but what hose do I need? T2 hose or FB hose?

J Oliver

All my stuff is FB ie: slave and master with FB hoses.
??????

setzep

you are using a FB slave on a T2 trans? Or do you still have a n/a trans in it?

J Oliver

It is a TurboII trans, I took it out of the TII and put it in my FB soooooooooo I would hope it is the stock trans. Ya it is. And yup it is the stock FB slave, I work her reeeeeeeeeeeeeal good!!!!!!
WHOA, did I just say that out loud?
