I was going to do a little show and tell earlier but I figured I'd at least get a little was into the project first. :secret2: The simple run downgoes like this, 5.3l for now ( forged aluminum 370 over the winter:devil:) T76 for now (80-88mm over the winter:devil:) 4l80 stick shift to syclone tranfercase to s10 front differential, and infinity q45 rear. also I plan to keep it under 3000lbs Its a bit more complicated than that but thats the basic plan.
Some body is probably asking them selves why would a person do this? I want my car to be all purpose. A car set up launch hard typically sucks when when you ask it to turn hard. and the inverse is true. Ask a hi powered 2wd car to accelerate hard from a roll and what do you get? smoke and rubber, fun but not so effective.
Most of the hard parts have been purchased and are in my garage the big variable left is the the torque converter. Also drive shafts still need be made. I'm thinking a 5 clutch vigalate around 3500 stall. For road racing run it locked in 2nd-4th with a button to unlock for down shifts (sort of a poor mans sequential) for drag racing run it unlocked I'm thinking I can get the best of both worlds. 4 gears should be plenty for a turbo motor and my gear will give the car a theoretical to speed of 206mph. with a goal of around 650 at the tire it should be a gear limited speed.
thats all for now here are some pics of the car, the old sr20det setup and the progress so far. I still have a long way to go.

The oil pan is a modified moroso pan. I forgot to take pictures of the modifications. i have to take it back off once the final turbo placement is set, I still need a drain back. (its similar to the truck pan in the faq that was modded for a sy/ty. The pan is so close to the crank that I had to cut the windage tray to clear the pan.
the front sub frame has bee taken out. the engine has been mounted as a stressed member of the chassis. no rubber or poly anywhere. the engine bolts in and with the two very stout mounts and becomes the link between the left and right frame rail. the axle solid mounts to the motor mounts. on the right it uses the stock mounting ears on the axle on the left its uses the three bolts you can see in the pictures. (does that make sense?) I will try to get better pictures soon.
I am a bit worried the the axle is now the lowest point but it still hangs no lower that a typical bodykit front bumper so I should be fine. (plus s10 parts are everywhere and cheap.)
Are the diff ratios the same you ask? no. before I get a lesson on why it wont work remember that I need the diveshafts spinning the same speed not the cv axles. tire size will make up the difference. with that factored in drive shaft speed will be less that 1/2% difference. that is not enough to cause problems. (when you drive in a circle drive shaft speed difference is more than that)
the car already has an j30 rear end and z32 hubs so that should not be a problem the front will use s-10 hub assemblies re drilled to 5x41/2 bold pattern or ford ranger hubs. yes s10 axles will fit in a ford ranger hub. with a little work) who would have thunk it huh? (ranger hubs are 5x4/12 like Nissan)
I'm currently in design phase for the front control arms. I plan to get the roll center back where it should be.
SirWarrior
05-29-2008, 01:02 AM
OK, first of all, HOLY SHIT. thats a lot of different than I expected
Second - I was asking, because some people might not realize to make the wheels spin at the same rate is important - don't ask, but I've seen too many people blow their diffs that way.
Third - pics of all this jibber-hootie going on in your front wheel wells. Mainly I'm wondering how it all fits together.
Again, good luck, I hope it will run as you want it to.
PS. are those rivets in your strut towers?
Professor_speed
05-29-2008, 06:03 AM
I,m currently finishing up the motor/axle mounts. (they needed a little modification from the current pics. the control arms will be next, first I have to pin down exactly what im going to use for steering knuckles. I'm thinking aluminum GM front wheel drive stuff machined to accept s10 or ranger hub assemblies. I can't build the a arms until I have that nailed down so I can locate the wheel in the same place as stock.
The trans, transfercase, and front axle has held up to 8's for the sy/ty boys, and that rear diff is near indestructible so i don't think I'll be breaaking many parts

So i hit the junk yard picked up front knuckles and after figuring out what i thought would work would not, at least not with out a lot of machining.
The original plan was to use grand prix knuckles with s10 hubs. s10 hubs have bearing pilot hole about 1/8 to big. so i figured i had have them turned down. (there is plenty material.) then they would have to be re drilled to the proper bolt pattern, for the wheels, then they would need the mounting holes welded and re drilled to match the steering knuckle. id be 300to 400 dollars into bearings per side. but hey i knew this going in.
I got home with knuckles and is aparant very soon that those knuckles would work but would be far from idea. The mounting location for the tie rod was too high in relation to the ball joint. I knew it would not be perfect. My plan was to use bump steer correction tie rods to get them where i need them. they would need to be about three inches with this knuckle :bang: that just sounds like a snapped tie rod to me.
So back to the junk yard. 05 malibus use a very similar design but the tie rod mounting point is much lower. problem solved right? well not wanting to spend $600+ on bearing i thought why not just use hub assemblies from the malibu and have the outer tulip switched from a malibu cv axle to a s10 cv axle. ( still believe this would have worked.) they appear identical.
I got to thinking (not good, thats how i got myself in this project in the first place, I have an enlarged medulla-bad-idea) s10s where designed way before any of the stuff I have been looking at for hub assemblies, so why not try one from that era? long story short 88 cutlass fwd with hd brakes has a hub assembly that not only has the proper bolt pattern for an 05 malibu knuckle, and the proper hub pilot size, and 27 spline axle that s10 use, and 5x115 bolt pattern which is close enough to 4x114.3 to fit my wheels and brake rotors. gotta love when engineers don't redesign stuff for no reason, and gm's ridiculous parts interchangeability
On this first day of the 6th month of 2008 A.D. The automotive gods have chosen to shine on me.
On a side note every response here has been positive same with syty/sgt, on the Nissan forum 1 reply and it was negative.

if you could source some gtr knuckles it would probably make the configuring of your awd system a little easier since they're closer to the stock 240 knuckles. also iirc full race was offering awd conversions for 240's w/ full skyline running gear, so you may want to look around and see what else is out there as far as the running gear is concerned. This will most certaily be a badass.

Professor_speed
06-02-2008, 06:31 PM
yeah gtr knuckles were the obvious choice but would actually be more work. gtr and s13 have completely different front suspensions. rears are basically the same. I've spent quit abit on my current suspension set up. to switch to a gtr set would require new coil overs and adding an upper control arm. you could argue that i would then have a superior suspension? Ever tried chasing a well set-up Porsche at the track? they do just fine with front struts and multilink rear. also getting s10 axles to gtr hub assemblies would not be easy. Ive looked at many options from an lsx mated to a gtr transmission to using a gtr front axle to g35 awd front diff to bmw awd front diff . any set could be made to work but in the end it came down to availability, cost, and strength. gtr uses 160mm 6.3" front ring vs 7.2 for s10.
s10 diff $100, bravada tranfercase, $150 skyline anything $$$
craigbb
06-02-2008, 07:16 PM
have you looked at the design of the awd system on the holden HSV coupe 4..they did similiar to the rb26 in that extra clearance is made by pushing the front diff axle up into the oil pan area..then you could still have a crossmember joining the frame rails..without a crossmember how are you going to mount a steering rack?
1dirtyZ
06-03-2008, 06:45 AM
craigbb has a good idea there, the holden pan has the diff built in , plus you can get a transfer case from the same car that would be smaller and lighter than a truck one to mate to the tranny you have.
only down side if i remeber correctly is that the car will have to be rear steer , i.e. the rack would be behind the front axle centerline.
Professor_speed
06-03-2008, 07:04 AM
actually holden stuff would have been great. but tough to come by. 240sx stock is rear steer. it will be front steer when im done. holden stuff is simular to tbss oil pan in actuality it passes through the oil pan, but it is not as close to the crank as I would like. part of my oil pan is so close to the crank the windagetray had to be cut out. I also had to cut an ear off of the block (square untapped, unused boss down by the oil pan)
the plan is put the rack in front of the diff.
again the parts choice was largely due to what available.
the trasfercase is a bit of weight but its automatic in its operation. no electronic clutches to figure out. and all the weight is right in the middle of the car. my car weighed under 2700 pounds to start id be surprised if I added 300lbs, and most of the added weight well be between the axles. if I over shoot 3000lbs, I have excuse for carbon doors and trunk

any pics of other systems would be great. keep the ideas coming. but for the most part my hard part are already in the car. (differential) i will need to move it 1/2 from the current set up but its no big deal. I'm getting a bit of axle bind.
I don't know and cant find what the holden uses for a t case but its probably not much smaller than a bravada t case. the holden has more power plus weighs probably just as much.

06-04-2008, 11:50 PM
I like the idea a lot.
You probably thought about it, but have you looked at the AWD setup that is used in the Trailblazer SS? That pan is setup for one side of the front axle to pass through if I remember correctly.

06-05-2008, 05:42 PM
It'll be a killer street/drag setup for certain.
Road racing, not so much. You might want to revisit your front diff choices as the GM front diffs are far from performance oriented in that realm. Further, with a 4L80 and transfercase and turbo, your gonna be putting on a bit of poundage and theres going to be some heat concerns with the tight fits.
What about a modified oilpan with a driveshaft through pan and set the engine far back into more of a front-mid-engine setup?
There might be some options with retrofitting a porsche front axle out of a C4S, it's been a while since I've seen one; but I *think* they are rather small.
It's very challenging to have a front and low V# longitudinally mounted for 4wd use. I always imagined it as being a front mid-engine with the the trans output being a little behind the center line. Transfer case with small diameter driveshaft then running hugged next to the block on the passenger side. Granted, AC might go bye bye. Basically very similar to the new gtr, but it's still a bit too high mounted.

Basically very similar to the new gtr, but it's still a bit too high mounted.
I'm not sure what makes a front diff performance orientated. an lsd? yeah that would help. awd cars that don't turn well generally have a suspension tuning problem. Or have front biased torque split. I have 62 rear 38 front. for the most part it will act and drive like a rear drive car, with more traction for acceleration.
all the pass through axle systems I have seen do not get the axle any higher than I have it now.
My engine is no higher in the engine bay than the other 240 to lsx swappers.
my engine is further back than most 240 to lsx swappers.
Most of the added weight is in the middle of the car and low down.
the 4l80 will have a 5 clutch torque converter that will be locked 2-4th gears for road racing. this will keep the converter from super heating the fluid which will have a large dedicated and ducted cooler and a fan if needed.
the car will run a small diameter drive shaft. tucked next to the block but on the drivers side.
c4s would be too hard to make work. its not the configuration i need.
I was originally going to use bmw 330ix stuff but its too week. this diff is larger than most car front diffs but smaller than most truck stuff. so it will hold up to any thing I throw at it. It also came in many ratios and is cheap.
and again Im starting at about 2650lbs. even with awd it will weigh less than any thing that came from the factory with an lsx.
Professor_speed
06-08-2008, 11:52 PM
OKcrusing I did some asking around, and evo sti and gtr guys swear by torsen lsd's in the front. :bang: GM 7.2 only has a locker available. (obviously that won't work) I did a bit of research and the front differential for an explorer has a torsen unit available. I guess I'm going to switch. Dana 35 is 7.56 ring gear so its a bit larger but it has a low pinion vs. the high of the gm 7.2 and it comes in 3.55 gear ratio. I wont need to run staggered tires. the axles on the wheel end fit into the hubs I already have. I'll get some pics up once it is in.
Professor_speed
09-21-2008, 10:16 AM
quick update: front suspension is in, front axle has switched to tbss set up that is also in the transfercase is in, looking to get the front drive shaft in today. I still need to make across member with a transmission mount, but the motor mounts are so strong that they will support the 4l80 and a t-case hanging of the back. While I'm in the garage I'm going to snap some pictures
I made three different sets of motor and from axle mounts before deciding that this is the best route. the engine had to move up relative to the chassis and now sits at a 7 degree slant which I'm not found of but i think it will be fine.

-transmission is a 4l80 with a trans go hd-3 stick conversion
-torque converter will be a precision 5 clutch (so it can operate locked for road course driving, and keep the heat in check. poor mans sequential :pimp:)
- transfer case is syclone/typhoon/bravada with a George Blake/Prime gears custom input shaft/adapter to fit 4l80
-front drive shaft- astro van

Now that is definitely an "out there" concept. A great concept, mind you, but out there.
I applaud the effort, and look forward to seeing when it is complete.

I'm looking at how low you're transfer case is hanging, Are you using the syty 4l80 adapter plate and the syty transfer case adapter? You need that to clock the transfer case in the correct position.

all parts are clocked as they would be on typhoon conversion.
I got a deal on a ls1 so I decided to build that up forged internals oringed heads etc, going twins instead of the tc76. I live in Minnesota the high today was -6 so progress has been slow. but still plan to have it on the road come spring.

Should be fine then.
That's while I'm in here bug, I've had mine finished at least 3 times.had the engine in and out at least 10 times!! LOL, I thought about twins but all my gas and oil plumbing is on the driver side, no room for a downpipe.Cool project, stay motivated!!

um its actually bad to run a syty without a front drive shaft. you should be ok with the axle disconnect and the driveshaft in though.

Nice build...
Transfer case is a little to low, but if you protect it, it sould not be a problem.

Actually with the front axle disconected you will smoke the T case in a matter of minutes. You have to have the awd working all the time or it will grenade itself. Change to an astro van one piece left axle and eliminate the switch. or change to a auto 4wd T case that you can lock or unlock at will. Even then it will be harsh locked up. No give in the clutch pack. G

No give in the clutch pack. G
Actually, it's the right (passenger's side) axle shaft that is the single piece / 2piece assembly. And the Bravada single piece shaft is probably easier to find, they're pretty plentiful (any year Bravada has that shaft).
Do yourself a favor and just don't run this in 2wd. The viscous coupling in the BW 4472 doesn't appreciate it. Yes, you can get away with this for some amount of time, but its a matter of time before you completely cook the VC and it remains locked all the time. When that happens, the vehicle will no longer be AWD, it'll be 4wd high (no longer any differential action front to rear) and it'll try to hop tires around corners. Check on SyTy.net if you don't believe me. BTW, a replacement VC is in the neighborhood of $500 to $600, so it's not the most expensive oops, but not cheap either.
The "On-Demand" transfer cases (like the NV136 or 246) could be made to work (with a bunch of effort), but I know you've got a bunch of money invested in the existing setup, which will work just fine for a really long time if you don't try to run in 2wd.
Also, be warned that if you run it in 2wd (either with no front propshaft or the axle disconnect) use the parking brake or wheel chocks. Without resistance on both shafts of the Tcase (front and rear outputs), the VC will allow the vehicle to slowly move. Some Sy / Ty / Bravada / Astro owners have been very suprised when they removed the front shaft, parked somewhere, and the vehicle wasn't were they left it when they returned. Typically doesn't move fast enough to do damage, but you never know. One of the SyTy guy's recently related that he parked in the driveway with no front shaft. And figured out he had a problem from all the honking horns from the road out front. His truck was in the middle of the street, just sitting there. Didn't hit anything, but certainly could have done something stupid.
Otherwise, keep wrenchin' away on the project. And stay warm!

i would loose the bm ratchet shifter in a heartbeat and install a compushift tranny controller and a twist mashine steeringwheel paddleshifter.. have one in my Bu and its awesome... that way you can have a toggle to change between full auto, and full manual driving....

looked through this a little bit, and from what i saw you didnt have front wheel clutches, as an awd would have. maybe i missed it, or just cant read right.
but thats one of the major differences from awd and 4wd, and if you dont and it is 4wd. then its going to suck.
another thing is, that the weight transfer in this beast is crazy amount of up front death.
its and awesome looking project cant wait to see it done.

wtf is a front wheel clutch? The difference between a 4wd and awd is pretty much all in the t-case. what is up front death?

This project is not dead although it spiraled way out of control (budget wise), I also had on one of those adjustable rate mortgage deals, so that sucked up some excess cash for a while.( I got that all straightened out, its actulay less now than before the adjustment) I got to the point where everything is mounted and front suspention was built. Its all back apart now to make some tweaks and go back at it. I also took a break to put heat and insulation in my garage so I can work on it over the winter. (The high for to day is 6 degrees it was -4 when I left for work!!)
I'm also still gathering parts. I just got my 160# injectors if that gives you an idea of the kind of power I'm after.

How can you run a 3.42:1 up front and a 3.55:1 in the diffs? Doesn't that fry the transfer case?

How can you run a 3.42:1 up front and a 3.55:1 in the diffs? Doesn't that fry the transfer case?
Not if the tire sizes account for the different ratios, i.e. the 3.55:1 axle has a taller tire than the 3.42:1 axle.

12-15-2009, 01:30 PM
Very cool. Is that what's being done on the sy/ty?
Professor_speed
12-15-2009, 06:54 PM
No sy/ty runs same tires and ratios. So much has changed since the beginning, and I may end running the same ratios front and rear. I don't like the idea of staggered tires so im working on another solution. I don't post much because until I have it nailed down its pointless.

compact T-case but its the wrong side drop for your front diff.

How does that one compare in size and weight to the syty?
I've read this thread through twice now and started an excel sheet to figure out when I can afford a huge build that spirals out of control.

Your build just made my build look like child's play, I get frustrated working on my ls1 240 and i used a kit, I couldn't imagine building an awd/turbo/650hp/ls1-240sx and then manage weight placement final drive ratio's. It takes a crazy MF to build a badd ass car i guess. Any more progress?

08-13-2010, 09:27 PM
One more thing I have read the entire thread and I saw that you are using the q45 rear diff and later you said you are rethinking on what your are using for diffs, or at least thats what i understood. If you took the q45 diff out are you selling it?
