KF-ZE Conversion to RWD

Does anyone know of a gearbox (eg. Grand Vitara) that could be used to covert a K series engine into RWD?

Now before everyone tells me that I'm insane , I already know that. However I own a damaged eunos 500 (front end) that would make a great donor into a new toy if I can get the engine sorted.

Thanks

wouldnt touch somethin like a 4wd gearbox...cause unless you want AWD you wouldnt need it...

i thought some of the 626s or the 929s were RWD so one of them would able to be used i suspect...youll have more issues with the rear floor and subframe with diff than anythin else...

82 626 were RWD, 83 they made the transition.

the 929 were always RWD,

Mx-5.
If the V6 and I4 transmissions in the Astina share a common bell housing then the BP powered Mx-5 trans should bolt straight-up. Flywheel and clutch may be an adventure as will the starter motor.

Also you'll need to redo the sump, can't the motor over etc etc ... BajaWes from teh MX6 forums has a RWD instal in his Baja Bug which may shed some light on the orientation for oiling purposes.

I don't believe the 929 v6 boxes match the KF/KL pattern as the JE/JF family were a RWD only development.

Hard way
get a K series gearbox, cut it in half
find a Toyota Supra or something box
Weld/Grind, adapt etc,
flywheels, starters, etc

get Rx7 LSD rear end
and watch the money burn...oh and rubber

Easy way
Get a J series package (complete)
get Rx7 LSD rear end.

and watch the rubber burn

or just buy a real wheel, simpler, easier, cheaper, less messing around and less chance of s*** breaking. And when it does, replacing it is a simple swap which wont require a custom job of some sort.

Or find out what car the engine would go into before making random assumptions.

there is No box that will bolt on.

You just do what anyone else has who has used a K motor for RWD conversion be it race sedan or off road. A custom bell housing adapotor.

IMO only one box I would use if your going to go Large and it would be a Tremec or similar.

and why a KF - why not a KL get some cubes into it.

what r we all talking about? The engine mounts east west not north south!!! Where are you going to find the North South mounts?!? You really think the 929 was an E/W configuration with a gear box that had a 90 degree turn in it? Impossible. Only way you could do it would be to put in an AWD box and somehow lock the F/R diff so all the power/torque gfoes to the back.
Then you start with all the issues of 150 KW and 250 NM of torque going through a drive shaft made to handle half that MAYBE.
Then.... relocate petrol tank to boot (oy gavalt) dig a well under the car to accomodate drive shaft as well as rear diff.
And after that, i'm sure all your real woes will start kicking in.
In other words, good luck to you. Your going to need it.

Yeah

I must of missed something here, didn't think anyone was that stupid

Is the Eunos 500 or Ca chassis going to be used to make a RWD - LOL

God some funny ideas.

If you were to put it into another car okay. BUt A eunos 500 RWD -

Have you got money - my guess no Because the idea came from a free car if that's the case.

I get free cars alsmot dumped one m all the time - I can get anything just about legal and I have enough cash to play with but I'm not that silly.

It's not hard but Gee some people

DREAMERS

Glad to see that I generated some amusement for everyone! I am actally trying to get the engine into a Lotus 7 so don't have to worry about the Eunos itself which makes clearance of engine/mounting issues a bit easier to deal with.

For those of you who are stupid enough to consider something like this, I have found out the following:-

In 1995 a V6 Quad-Cam 24 Valve 2.0 litre engine was released for the LWB and Estate (103Kw @ 6500rpm and 177Nm @ 4000rpm) versions of the Suzuki Vitara. The engine was a joint venture between Mazda and Suzuki and it can also be found in a slightly modified fashion in the Mazda 323 Astina and various Eunos models of the same era.

The gearbox appears to be adaptable to a 2wd RWD format as the transfer cases are separate animals. So IT IS POSSIBLE albeit somewhat dopey.

My goal as this is my first foray into building larger toys is to have some fun and since I like the engine in the Eunos 500, I wanted to see if I could get it to work.

I understand that many would think this is insane - I probably agree with you - but its not whether it works in the end - its how much fun I have in between - although success never hurts

Anyway will continue with my research and go and get one of the above transmissions to assess how stupid I going to be.

It may be that I get a 929 transmission and mate it to a Sierra bellhousing...

Thanks all for the feedback and for those naysayers who doubt - its easy to point out the problems - its more important to find solutions.

Dont be fooled into thinkin there is any similarity between the Suzuki motor and the Mazda motor cos theres not
Thats like sayig the cosworth 2.5 (designed by mazda and ford) is similar to the KL of the same era when its different as well

Suzuki v6 is as close to a KF as the Lexus 2.0v6 is hahahaha

The K- series has more Owing to Porsche then it does to anyone else.
Car makers may share block desgin or similar to aid in production. But it's like the Mazda - japan made Duratec Ford V6's, they maybe the same but as anyone who has worked on a few already will know - Some parts just don't cross over.

Also if you made it clear in your First post the complete Idea no one would even consider it.

As for gearbox search it's RWD- Adaptor plate. Or if you really want to try mod the bell housing.
You don't need a really strong box either the KF is a weak motor. the KL is where it starts to make something but
BP N/A makes more torque down low - where it can do damage compared to a KF.
you could use a simple 1800 RWD box from a old Rolla would do the job.

I'd look at space and ratios available. You will need tight ratios and use your diff to get it where you want it for over all speeds.

The 626 RWD had the MA (puke) two litre. Nothing to do with the KF and that's the last I'll say as I'm getting too many ideas.... 626 coupe with a KL-ZE...
