I know this is probably covered about a million times a week
but what is involved with putting a 13b turbo from a FC into a FB
I've got a spare 12A motor so I can use the front plate off that if that'll make it any eaisier?
also would it be better/eaisier to put a 12A turbo/13B turbo gearbox in it or how would the standard 12A non turbo gearbox deal with the power? if either of the 12A ones would even fit
also what other drive line changes would be required?

do a searh on turbo first gen or 13bt first gen. you need a 12a or gsl-se front pltate amd se oil pan. to get the motor in your car. depending how you drive a decent 12a box will work but not last tooo long if you make any amount of power. putting a turbo box in can be a bitch (i know) ut it can be done fairly easily. i just left the shifter location alone and hacked about 1" back ad i fits perfectly. then you have to get a custom driveshaft.

Will all the motor mounts line up fine for the swap or do they need to modified as well???

The mounts will line up IF you either have a -SE or get the racing beat 13b adapter for the 12a cars. Because the 13b is longer they made the mounts on the crossmember farther up compared to the 12a crossmember. The racing beat engine mount is just offset to allow you to bolt in the longer 13b.

Rx7passion is right about the gear box its best to use the turboII one but its a PITA to make it fit right without modifing the shifter tunnel. If you want the shifter to stick up in the right place without modifing the tunnel you will have to swap the extension housing from a 12a tranny to the Turbo tranny other wise it sits 1inch too far back. Im in the process of changing the housingings over and and having the shaft inside shortend and redrilled so that it will stick up in the right place will have pics soon. As for putting the engine in the car thats no big deal just use a GSL SE or 12a turbo front cover and a GSL SE oil pan and slot the motor mount back and it will bolt in. As for racing beat mount they are on back order and they have no idea when they will have them again. The advantage of the 12a turbo cover is that the oil return line for the turbo is already there although im not sure if the 12turbo cover uses the OMP with 4 oil lines which the GSL SE one does. Hey Rx7passion do you have any pics of how you modified the 12a tranny mount to line up with the TII tranny? Ive looked at that many different ways and still can not decide how im going to do that.

Ok one problem guys..

I'm in australia and im pretty sure we didn't get those model designation's like GSL-SE and stuff like that..
but from what i can tell they came with an injected 13b yeah?
all the 1st generations that came out in australia came with a 12A im pretty sure.

so would putting in a 12A turbo be a better idea? or could the motor mounts be changed to suit a 2nd gen 13B Turbo pretty eaisly?

rx7passion

how much did you shorten the rod inside, i tried to figure it out but it was being to much of a pita to get it all to fit just right for 1.25" of location. i would love to see what you did so one day i can change it back

and about the pics i dont have them developed yet (old fashion) but i will pretty soon. all i did was just tap the housing cause again its about a 1" off or so from the 12a mount holes. put some big hurkin bolts in there with a few o rings to help vibration. i doubt it will be horribly bad because the 12a mount has alot of rubber around the chassis mounts.

and pstn klr its called a series 3 over there. series 1 older rx7 with different tail lights. series 2 has newer tail lights and lsd's in some of the models. series 3 is top of the line with 13b and upgraded suspension.

REVHED

Nope, even the Series 3 only came out with the 12A over here. And PSTN KLR, you'll also need a custom exhaust manifold for the turbo to clear the stearing box. Either that or you can offset the engine but IMO it's easier to get the custom manifold. And if you're interested I can give you the number to a place here in Brizzy that has brand new 12A turbo front covers and 13B sumps to suit Series 1-3 Rx-7.

I'm planning on doing the same thing, good thing is I have NINE 12A transmissions to pick from (most of them are good too :p) So swapping the tail assembly or whatever it's called, should be easy for me.

PSTN KLR here is a great page that I found a while back thats been a lot of help. http://www.geocities.com/MotorCity/G...5/webpage.html

Its an australian page so it explains how to move the turbo froward to clear the stearing box and some info on how to wire things up.

Rx7passion I should have some pics in the next couple of days I had to take the tranny to a shop to have the shaft cut and the hole drilled I did not want to screw it up. Right now they are having problem lining up the hole for the pin in the right place they could get it to go into every gear but reverse. Ill try and get some info on how much of the shaft was cut off and how far back the hole was drilled. Ill also try and get some pics from inside the extension housing.

it is really easy to do... run SE front cover or 12a turbo cover. I'm running a 12a US spec front cover(modified to use 4 outlet metering pump). Se oil pan. You can run the stock 1st gen tranny you have. But if you run a 88turbo motor you have to use a 88 NON-TURBO flywheel.89 t2 runn 89 non-turbo flywheel. I know a few people running about 400+hp on the 1st gen tranny and works fine!! I swaped to the turbo2 tranny just because I got one real cheap and i like drifting(i'd The swap was easy. turbo clutch slave.. run the same clutch master.. turbo starter.. run 84-85 drive shaft with turbo yoke. The leight of the shaft is perfect!! dont' forget to run turbo clutch. The cutting of the tunnel is no big deal I mounted the 89 tranny in with a little bracket i made to hook up to the stock cross member and then I just plazma cutted it. The shifter doesn't even sit far back at all. If you're in Australia check out local rotary shop b/c pretty much everyone there does the swap. www.dysonrotary.com.au
