Potential project opinions needed!!!

SHPmainMAN · 02-23-2009, 11:15 PM

I am going to need a few smart opinions from some people who have been under a few cars.

Just recently i was bitten in the ass by the offroad racing bug. But i have this disease called "Rotary" running through my blood.

So i am contemplating a very custom project called 1.3RS, some of you may already have an idea of what im thinking of.

I want to take a Subaru 2.5RS coupe maybe around a 1999 or a bug eye 2.5RS and mount a transverse 13b into it to retain the AWD. i have not researched into this project really at all. i have not looked at the transaxle of the Subaru nor have i really dove too deep into fitment issues.

If this project is possible and i have enough support, i will continue this venture and i will most likely be fabbing a lot of parts for this project, but i am willing to start this if i can get some opinions on it and some help on research.

I guess the first step is to pull the engine in my TII and start the porting. Then im going to have to find the subaru donor car.

i wont lie. i have wanted to do this EXACT project for a long time but like the tools. The 13B is not as long as a boxer engine and i think that it would help reduce the frontal weight issue the motors have.

That said i would buy a kit from you. or two.

Don't do the bug-eye...it's fugly.

Go look at a subbie and check how the engine is mounted......I'd be interested to see this swap just because I've never seen it before.

Whizbang · 02-24-2009, 12:33 AM

its mounted like a typical rwd vehicle.

I meant the mounts...isn't the subbie mounted transversely??

How's the awd set up?

Yeah, I knew it was layed out north/south...Thats why the whole transverse comment through me lol.

WE3RX7 · 02-24-2009, 09:47 AM

Should be doable as far as the fitment. I often wondered this project myself as I love the 2.5RS body...

It will definitely take some fab and some patience, but there wouldnt be anything like it for sure, and if you could simplify it enough, I'm sure you would be able to sell kits based on the design....

RotaryProphet · 02-24-2009, 09:56 AM

The only issue I see really (as long as you're willing to make your own motor mounts and such, which it sounds like you are) is finding (or making, if you're brave enough) an adapter to fit the 13b to the original trans, and locating the starter, as it looks like the axles on that trans will wind up in the same place as a Mazda starter. Didn't they make a rotary with a top mount starter at some point?

Clutch disk is easy, there are lots of places that will make them custom for you, with the Subaru input shaft splines and the Mazda diameter.

bigtony08 · 02-24-2009, 10:06 AM

i would be worried if the tranny and driveline could handle 9grand and not break cause subaru axles def are not the strongest

SHPmainMAN · 02-24-2009, 11:43 AM

ok now that i just got learned on subaru, and i know that they dont have transverse engines... i am a lot happier, and thats going to make this project a lot more fun. Thanks for the input guys, if you have anymore please let me know.

SHPmainMAN · 02-24-2009, 11:58 AM

as far as mating the engine to the transmission its going to be a custom fab job by ME! And i will have to find a way to mount in that starter, but i will find a way. as far as the strength of the drivetrain goes does anyone know of strong reliable interchangeable parts that i could use in place. Either way the tranny will get a whole new gearset for the tranny, and new front and rear drive axles probably looking to retain around 450hp.

So i guess i will put this project underway, if a mod or someone would like to could you please change the Topic title to "1.3RS"

SHPmainMAN · 02-24-2009, 11:59 AM

oh and BTW im looking for a 2.5RS coupe around michigan if anyone knows of one.

djmtsu · 02-24-2009, 11:59 AM

Kennedy Engineering makes custom adapters to mount just about any engine to any transmission. Look them up.
