Default any kits for converting to FWD?

first, this is for a specific application, so please lets not get into the 'why' aspect. this isn't for a daily driver or anything.
TIA



like the title says, I'm basically looking for a center diff that's 100% FWD or something similar. I searched, but only found stuff on converting forresters,etc to FWD electronically.

this is on a 2004 WRX built 5speed.

2nd question....lets assume 350whp, will that kill the front diff completely? OH....Carbonetic 1.5way LSD. The course would be half dirt, half tarmac....short race intervals, the whole RallyCar RallyCross venue thing.


last question...who makes some decent upgraded front ring/pinion gears?

^saw this thread and thought the exact same thing. I'm sure the majority of us here bought a Subaru because of the AWD.

I bought my WRX because I crashed my FWD Accord in the rain... the AWD was a huge confidence boosting factor in the purchase...

LOL....1) morons....READ my post, maybe the part in BOLD, perhaps??? (same to drifter2be and smallville) Sorry if you don't understand the reasons that I already said I don't feel like explaining to you, you just wouldn't listen anyway, proven by your above responses.

and 2) AWD won't fix your crappy driving, sounds like you'll eventually crash your Subaru too.


Andrew and 04stigeorge...thx for the replies. I'm just doing some advanced research for a potential project in 2012. if it works out, you'll certainly hear about it

I'm guessing mid engined rwd project.

If you have a look over at the subaru conversions forum you will find other folks working towards a similar goal. It's been done before..

All you would really need to do is weld up the center diff and eliminate what isnt used after it. Pretty straight forward.

^^ something else, but good guess I'll def check out the conversion forum, thx.

Yeah, a locked center is pretty straight forward, I'd prefer to buy that single piece than mess with finding an OEM diff and welding it up...for $240, that locking spline is pretty easy.

I was hoping someone would bring up something I haven't thought about, just trying to check all the angles. Going FWD the weak points are probably the OEM front axles and the OEM ring and pinion, and maybe the diff, but its a carbonetic front LSD, so it should be able to handle what I'm throwing at it.. nothing crazy high HP, as stated, but just wanted to get any helpful tips from the peanut gallery.

Listen up you primitive screw-heads....

The OP already stated he is doing something DIFFERENT so that's the reason why he's looking for FWD. Obviously you'd either have to be doing something different to even consider this, so quit trying to think you are being cute with your comments.

To the OP, I think you have exhausted us in terms of finding what you are looking for. I've been haunting this forum since you were in middle school and I actually learned the above link as a FWD source and added it to the Transmission FAQ. If I learned something...that's saying something. So, concentrate your efforts on it as I don't think there is another solution.

I wasn't criticizing your choice of going for a unique setup, it was just a casual comment.

Thanks for analyzing and making an assessment on why I crashed and will probably crash again. Glad to know your spectral spirit was there to witness everything.

Jon,
I hate sending people outside of our little NASIOC swimming pool but head over to 914world.com and look around. This gearbox converted to 2WD has become somewhat popular with the 914 Suby swap crowd.

The thing that I suspect will be the challenging part after you make the conversion is the shifter. I'm not sure how or if the Bremer kit changes the shift rod location and throw length. You might have to get something fabbed up there. And as you are already aware, the shift rod for our dog box kit that you are running is already a custom piece. If the rod needs to be altered and you ever want to go back to AWD you'll need to have us make and supply you with a new rod. But that's only if it's the rod inside the case. If the changes happen after that point, there's no worries there.

The other is as you suspect, the ring and pinion strength. The 914 guys seems to be seeing reasonable durability out of their conversions. However most of them are using Ej25 and Ej22 NA engines. Or at most a relatively stock Ej205 swap. There are a couple of Ej255/7 builds going on but I don't think there's enough time on any of these swaps to say for sure if the R/P can handle it. My professional opinion on the matter is no.

To my understanding, Subaru changed r/p factories about the time the v7 was released. The last of the 5spd r/p sets are nowhere near at high quality as what they were making earlier in the model life. So, what you might consider if you do this is trying to find a low mileage Legacy core gearbox from the early 90's with a 3.9. Or maybe you don't want to stay 3.9 with the conversion. Then the 4.11 and 4.44 FD's from the late 90's become an option.

If you do want to buy an aftermarket r/p set, you know where to find me. You also know what kind of money it takes to swim in that pool.

And to the WHY whiners, I'll add one more thing to think about. There's certain sanctioning bodies in racing who require that a rookie run 2WD and get a provisional license for a season or even two before you can get a full AWD license. While you boy racers on the street may have bought your car because of the AWD, for a real racer, going 2WD for a couple of years may be part of the path to becoming a real rally racer and not just dreaming about it while sitting in mom's basement playing GT5 on your Play Station...

Te part in that kit looks like the sst for disassembling a su baru trans. Wonder if the tool would be strong enough?

Thanks Matt, I knew you'd chime in here....and as this gets closer to reality I was going to give you a call anyway and let you in on my evil plan.


I'm sure a Modena R&P is mucho $$$, so the legacy option might be worthwhile, as I'm staying with 3.9 FD. But I'll still want to see a quote from Frank eventually....always fun to splurge

been chatting with the Bremar guys over email and how their locking spline installs....I get the feeling its a lot thicker than it looks.

I have done a mid engine setup with a stock FWD manual trans in my open wheel subaru powered car. http://www.youtube.com/user/pa028911#p/u/12/9eFEBqMEu5g Have had several of these apart and in my opinion the trans should be stronger than the AWD version as the secondary shaft is integral with the pinion gear, not a hollow tube like the awd. The bad part is there is only 3.70 gears available for this transmission, and with a turbo and the 1-2 gears, it really drops speed after a launch. I am now working with a Forrester trans with 4.10 gears but Bremar is out of stock until late this month or early next month. I use an all mechanical shift linkage similar to the formula Vees on mine, but am working out a sequential shifter now using an automatic ratchet shifter and solenoid assist with paddle shifters. The series I am running with hill climbs makes it tough to keep your hands off the wheel. Other issue is that the clutch in the older push style trans gets overpowered quickly, even with a 3-puck, so I put a case on from a turbo car to help with that.

pretty common for people that don't want to buy a new car when moving from group 2/5 to open/openlight rally cars.

I've seen cars that have had similar plans and it's not pleasant. There is a lancer with a built evo swap in it (~400whp) and it's WAY over kill for rally. Especially rallyX... you'll be doing burn outs non-stop.

Default AWD reverse kit

IS there any such kit for reversing the entire gearbox and all three outputs ?

I want to put the running gear into a buggy while maintaining AWD, but mount it 180 degrees out. Obviously you could do this without the kit and just always run it in reverse but it would be nice to have more than one speed

Yes, i believe subiegears has a diff flip kit as well as the fwd conversion for various mr, vw rr conversions. I have the 2wd lockout and rear tail section pieces for an mr project i've piecing together.

UP2MTNS. . .did you ever get this figured out???

We are trying to do something similar with a '17 STi transaxle. . .running the STi transmission in a mid-engine set-up and using the front axles as our only axles (in a non-Subaru vehicle and it's not a Subie engine either).

I'm trying to figure out how to lock-up (or lock-out, whatever you want to call it) the DCCD so that 100% power is always delivered to the front axles.

If you (or anyone else) has info on this for a manual STi transmission please let me know.

Thanks!
