I never said there were problems with steering did I. As far as drive getting used to it.. i am used to it. The car is going to be built for racing purposes only....so no awd is not better then rwd. (autocross)

I was asking if people have done it or know someone who has...not tell me why i should not do it.

Please excuse us all to hell. Now that you've revealed the Secrets of the Pyramids about WHY you want to do this, we can offer the same answers: the factory drive system isn't strong enough to handle pushing and braking the whole car on its own without failing. The RWD DSMs that are used in competition are done by building a RWD scheme under the original shell: there's not any rolling around known of that are modified out of the AWD or FWD drivetrain.

christ.

:rolleyes:
 
Defiant...where in my post(s) did i say i was going to use the factory drive system.. You keep saying things that are well know. "the factory drive system isn't strong enough to handle pushing and braking the whole car on its own without failing"...yea i think most people know this....its obvious you dont have a rwd or personally know someone who has so shut up and stop posting plz

Uhh... pardon? From the VW Bug to the Sprite to the Datsun 2000 through dozens of other Datsuns, the Supra and a few pickups- I've never owned FWD.

And yes, the posting will stop.
 
Does anyone have any first hand or second hand (third hand and up and BS talkers need not apply) experience doing this? How did it go, what was involved, thanks.
 
Do you mean to turn the engine 90°, get a RWD transmission and a real rear-end, or do you have some idea of using the AWD rear drive for this.

Because the first way will work, and the second won't.

Oh, and just as a heads-up for some of our more delicate members, this thread won't have a long life. It's been much-discussed before. But we'll see what washes up on the beach, first.
 
More detail is needed. What's your plan of attack. Motor, trans, etc...
 
I can't believe you guys knocked me for wanting to put a North-south AWD Skyline Drivetrain in a DSM, and then willingly converse about making a DSM RWD, which is DUMB.

oh well, lots of weird people in the world.

IGS, I 'd like to say that if you have to ask your going nowhere with it, BUT don't ever let anyone tell you something CAN'T be done...like some of the people on this site.

PM Morphius, he's suceeded in eliminating two drive wheels, a turbo, and adding 4 more cylinders in a DSM. ;)

peace
 
I'm thinking an engine-back mod. That's not possible? Can't I just lose the center diff?
 
you could rotate the engine and put in a mighty max tranny. of course it has truck gearing, but then again i hear the gears and shafts inside the transmission are the same as a conquest. so you swap it out and the tranny bolts right to the block. i believe that is how the conquest 4g63 swap guys do it.
 
1) Get a welded center diff. Insert welded center diff. Remove front drive axels. RWD is now obtained.

2) Have a custom built center diff that sends all the power rearward. It can be done and has been done on other AWD cars. Go see the latest rice mag issue (I think it might have been Sport compact car?) which had a RWD biased diff in the WRX. I'm sure they could build a RWD biased DSM center diff.

3) Sell your DSM and get a RX-7 or 240SX with an SR20DET (Best option).

Just don't run a lot of horsepower or you'll be breaking shit left and right. The drivetrain is only made to take half the power you're giving it, remember.
 
Ok this has gotten out of hand. Someone lock this thread.

????????? Where does that come from?


If you are simply keeping the transverse mounted engine (ie stock) then the best info you will find is what cait sith stated. Do a search. There are a ton of threads with that "mod" discussed. Has anyone done this and run strictly RWD? I doubt it. It's not real efficient. Alot of work for no gain.

Looking at a north - south mounted engine. For 4G63 powered cars there is the pioneer, Buschur. Or I see Rau is running a similar setup now. They have a world of experience there. Of course, they are purpose built race cars. I'm sure they wouldn't mind chatting with you on the topic.

As SpoOLxExO stated, I've got a V8 project going. It's not road worthy yet, but I anticipate having it out this spring. Is it alot of work? To some, yes. For me, no. I enjoy the fab work and find it fairly simple. I may be an exception given my mechanical background. At this point, I won't give out anything in detail about my setup. But if you have some specific basic questions, I might answer them.

Then there is the 4G63 starion/conquest crowd.

You simply aren't going to find many people who have done this. So, in reality I don't know how you can get away from this........

"first hand or second hand (third hand and up and BS talkers need not apply) experience"
 
Yes what cait sith stated is what I was originally thinking of. I just wish someone who has actually done this can chime in on the results.

Unfortunately, I don't think you will find someone that has. Numerous people could, who are running a welded center diff. But, given the build up of their car, they don't want to mess around with removing the front axles and take a chance in messing up the rear of the car.

Why not blaze a trail and report on the how it works?

Your 2g is running a 4 bolt. According to Shepard, the rear is good for around 500-600Hp/500 ft lbs torque. (That's after taking in account for launching and the weight transfer to the rear)

So, unless your car is highly modded, you should be safe.
 
Why when you open up Starquest web page there's this BUTT UGLY Subaru on the Homepage - WTF? Did the Website get hijacked?

& I think it's an interesting little thread BTW...
 
Yeah I don't know what happened there. Go to www.startquestclub.com instead. Their search is slow but you if you just look around in the engine and performance mods forum you could find something.
Also, the 4 bolt rearend might be able to handle some abuse, but what about the tranny? Isn't that designed to send most of the torque to the front wheels?
 
you know i just finally got the new scc issue, that issuse got me searching for threads just like this. my outlook is that i love dsms and especially the motors themselves but i love the fun factor of rwd cars like supras and most all drift-capable cars. when i saw about how relatively effective the rwd swap was. i immediatly thought of that for a dsm. it could be a really cool combo if done right.
but anyways, since there are beefier aftermarket cv axles out, wouldn't a stronger welded center diff, and possibly and strengthened rear diff be pretty much all that'd be needed?

I'll be the first to say that IF that is true. It's impressive. The link wouldn't work for me, so someone else will have to chime in on what the vid showed.

What I question is the statement that the car wouldn't dyno FWD. Someone want to explain how, on a dyno, the RWD makes it more dyno worthy? No weight transfer. Less weight on the rear, so what makes it an advantage?

Also note that, because he can lay down 821hp on the dyno doesn't mean that drivetrain will hold up to street/strip abuse. If Shepard is at the limits of ripping the rear diff apart at the power level he is at (and through 4 wheels) then how can you put 821hp reliably through it?
 
does anyone know of a place that sells a center diff that sends power to Rear wheels only?
 
I really would love to know can it be done and what it will cost to turn a FWD talon to a RWD. I like the All wheel drive but seeing a street driven RWD talon on the streets is something to see. The all wheel drive has to much to break due the the stress of turning all four wheels. Having the RWD and a pair of drag radials or slicks on the street and its as good. If anyone knows the cost and what parts are needed please let me know.
