well, im not sure if this goes into the conversion forum, but here goes...

Ive been wanting for months to do a rotary rebuild and porting project... Ive been slowly gathering the money. The goal of the engine is 240hp NA with minimal porting. I bought a totaly rebuildable parts car / engine with everything there. Ive now got the engine and bits. So then I started to look around for a good car and I found an 89 S5 GXL for $600 in almost imaculate condition. other then needing a sunroof and a paintjob, its in exelent shape. this is what ive been planing on since.

but, ive come across a friend thats letting an 87 SR5 AE86 Corolla with minimal rust go for $100, its got a blown HG and the engine is trash... so I was beating the idea around of swaping my S5 Project Engine into the 86...

My question is has it been done, how hard was it and should I do it? In theory the lighter 86 should suit the rotary well. that and most toyota bits can be had for cheap. My orginal budget was $1600 in the car running for the FC, that included buying the FC for $600, but with this, id be able keep that budget and have alittle left over to "play with" but then figureing the cost of mounts and custom stuff, id probably even out... also im alittle worried about the wireing too.

as far as the driveline and all, I figured that i would get it running and then look for the bits to convert it to an LSD and 4pot calps.

Any Opinion Welcome, but dont come and call me a bandwagon jumper :P lol

 

If your goal is 240 WHP NA with minimal porting your going to need to go with a 20b. Because thats going to be a stretch with a 2 rotor.


To answer your question as to wether it has been done or not, probably. Theres a video of a ae86 with a 20b turbo. So, someones got to have done a 13b swap into one if someones put a 20b in one.

And yes you should do it! I'd do it with a 20b though.

 

I think the mounting is the same as a TE72 corolla, if it is.................. I can sell you a mounting plate to bolt up your rotary. Let me know if you're interested.

 

i've seen "hachi's" with 12A's, 12At, 13B, -RE, -REW, and 20B's swapped in.... its not that hard "mounting wise" yes some fabrication is in order but the most you'd fab up is mounts but then there are ppl who have some mounting plates/brackets already made just as he^ said.

of course wiring is a whole 'nother ball game. im not experienced enough with that

 

Thats gunna be tight

 

well, so far my bigest worrie was the mounting, which we may have just solved. As far as wiring, I was talking to my friend(the one porting it for me) and instead of the orginal plan to use the VDI ports and some kind of porting he was going to do, we think itll be 800x easyer to use a carbed set up with a bridge to make 235ish...
The thing is if im going to do it, need to do it soon. or atleast get the plan up and running anyway. My other worry is that will the NA Driveline hold up to 235hp? and if it wont, can I atleast get it working and running and drive it easy till i can get a beefyer driveline?

This is going to be sooooo coool... I would LOVE to do a 3rotor swap, but being that 3rotors are $4,000 and im going to have. Once Ive gotten a place to keep it, ill start building
anyone got a carb setup for me for cheap?

 

Someone here is do ing it.

 

I love rotary Corolla projects.

 

ok, just letting you guys know, project RX-86 is a go. Im going to need abit of help from this forum and its members to do it though. Right now im planing the rear, and wanting to use a GSL or SE rear from a 1st gen, so I need to know the exact length of the rear. Im planing to use an FC TII Tranny, Driveshaft and then a GSL Rear. so that I wont have to fab alot of the driveline parts together. also if someone can help me figure a way to hookup the ignition, thad be great.
thanks
Tim

 

Keep me updated on the progress, because I am very interested in doing a 20B swap if possible(money wise), into an 85-87 Corolla.

The stock drive train will hold up just fine. I built t a turbo charger AE86 that made 292 Hp at the wheel and it held up just fine. But if your planning on going over 300 hp then maybe upgrade to a celica rear end or better.

Heres that 3 rotor AE86 ...... again http://www.turbocorolla.com/media/video/3rotorAE86.asf

 

Hmmm...Real driving and car shows are 2 different things. Let me drive it and I will tell you if its good or not.

 

I have a buddy that has a 1986 sr5 corolla ready but lost his job so we haven't been working on it at all. he plans to put a 13b in her and swap over to a gts rearend and rear disc brakes.

 

thats cool, but tell him i said good luck on finding a GT-S Rear
its hard as heck, im thinking of trying to use somthing else because its too rare

has he made a mockup and started making mounts? im trying to get ideas

 

...

In my humble opinion you dont need a GTS rear.
You are beter off with a 79-81 supra rear..or even a cresida 79-85 rear end..some even came 5bolt , disk brakes and same width 56.5inch WMS_WMS.
A 85 or older toyota truck rear fits nice too..they are 55"wms-wms.
So you gain almost 2inches. ..of and they are 31spline, gears available up to 6.00, spools gears etc..GTS rears are overexagerated.
..
we have an 12A powered 87 sr5 that has not been driven in years...maybe this is our year to burn up a few hondas.

 

Oh its you again......why am I not surprise? That car was not show worthy, its too ugly.

hey, do any of you guys know if theres a difference between the Middle Iron on an S5 13B Vs a Later Model 13B(GSL-SE)? I heard the mounts were different from the S5s, and im wondering if it would be smart to find a GSLSE Middle Iron and Front cover,
I know I need a carbed CAS and Ignition System. wondering what other bits from the older 7s I could use?
Also, which would be better for this project? A TII Trans or a GSL-SE trans? I know you can run the bigger Clutch/Flywheel with the TII, but is there a down side to using the GSLSE? I thought id be smaller than the TII anyway
thanks

This baby is a stock 13B with a T70 putting out 349RWHP/MT.

 

:shocked: so you guys finaly come out of the woodwork huh?

I was begining to think that Me and the Japanese Guy were the only ones with Rotary powered 86s. You must share your wisdom, Enlighten me... HOWD YOU DO IT? you nuts made it look easy. What Kind of Rear? Howd you mount it? I have sooooo many questions.

Just saw the turbo in the 2nd 86... are you out of your mind
that is just vulgar... I feel naughty now. how did you get that turdo in there? Very Nice 86s guys. are they both GT-S's?

 

If you are goin to go with a 13B or 13BT in the AE86 u dont need a GTS, because you are going to have to replace the whole drivetrain anyway. The GTS rear end will only hold 200 HP so better look for a replacement.. I want to do the same thing thow.. it would be fun..

wow, i cant believe its using the stock tmic with that turbo

 

as stated before...toyota truck rear end will bolt right up...or if you really want to go nuts a ford rear will also do the job.

the red one is clean as hell....however i agree with ^ about tmic and that turbo....you can get a fmic in there with ease not to mention it won't be completely visible so you'll still retain the sleeper look.

 

I know a Yota Truck will work, Im just trying to get rear Disk and LSD if at all possiable... If I could find a Yota Truck with Disk and LSD, ill jump at it. what would be the best truck to look under? 2wd or 4wd? and will ANY Ford Rear work?

as for the other two, question ontop of the other technical questions, how fast are these cars? more pointed twoard the NA corolla, is it like briskly quick or butt dyno says your thong whent up your crack quick???

now most importantly, Whatcha got packin? Mods? so forth? and most importantly, HOW?
