well, I REALLY don't mind BMW's being RWD, they've got a 50/50 weight distribution, and even if that weren't the case, my old man's 300hp V8 wouldn't treat the front tyres too nicely - WITH traction control, 235/60R15 tyres and an automatic in Economy mode he still manages to spin the tyres up pretty good...
my reasoning in this case is, when you accelerate the weight is shifted to the back of the car - if you make like BMW and get a 50/50 weight distribution, methinks RWD would be pretty desirable. My Nissan's got a weight distro of approx. 75/25, and that manages to spin the front tyres occasionally on dry pavement (100hp, auto, 185/65R14 Goodyear Ducaro GA's).
Does anyone know exactly what the weight distribution is on the '89 GL wagon? if it's something like, say, 60/40 or 65/35 then I might still give it a go
-
sweet
I'm aiming for a manifold length of around 2 to 3".Looks like I'll be having to make hood scoops anyway
at least I can do fibreglassing to some extent... -
But if you like RWD and over steer, and hate under steer, I can see why you would like it. I guess you americans are used to RWD anyway.
I'm not American - I'm to your east dude, not to your west
dual carbs and RWD... BURNOUTS!!!Heh heh heh, not to mention the weight distribution of said wagon...
good burnout machine I'd reckon, light behind, RWD, front parking brake, dual carbs, low range...
Still, not that I'd do any of that stuff but it'd still be cool
-
Ah yeah - I don't really mean nicer in terms of power etc, just that when you're accelerating/engine braking, torque isn't trying to steer the car, so the steering wheel permanently feels loose and you get better feedback from the road
-
Also - to sync the carbs, can I pull the idle screw on the slave pretty much all the way out, crank the throttles all the way open and then link them?
-
luckily yeah...
I'm wondering, should I put up a diary or something of progress?
As it stands at the moment, all I need is to go build prototype manifolds out of wood, digitize the design and send it off to my friend to construct them for me... then it's just trying to find a second carb and hooking up all the vaccuum lines.
As for the coolant, I was thinking hacking off the thermostat/temperature sender housings, welding them to a block with three nipples on it (one for each manifold + the heater core), welding nipples to the new intakes for the coolant, and fixing this new coolant supply thinger to the engine by the same mounts as the PS pump.
Quick question though: why does it squirt coolant onto the base of the carb (from below), and will I need to do this?
-
hmm... maybe a sort of a scale, with a kind of a flat chute type thing in the mouth of each carb - if one carb sucks more air than the other this'll make the scale tip, and I can adjust it to compensate...? of course, the two carbs won't be sucking at the same time, but I could just take an "average" so to speak of the scale position?
or is the difference in airflow not that apparant?
-
Sweet! I don't think it'll be doing any extreme angles, it's not lifted or anything
-
LOL, true, true - this is Auckland - don't like the weather? wait 30 minutes
that's actually a now-famous quote by Augie Auer at the America's Cup races - on one of the race days there was no wind at all, and he's like "Oh, if you don't like the weather wait 10 minutes", and sure enough, 10 minutes later there was a pretty good breeze going
Anywho - nope, not planning a drift car - just want to improve the handling a wee bit, it'll be a PITA to stop it from losing traction (already loses it quite easy just in FWD) but after driving my old man's RWD, I decided my next car's going to be a RWD as well
-
ASV's are a piece of crap that cause a lot of problems - look under the car, near where the exhaust flange connects to the head - on both sides you should see metal pipes comming out of the head near the flange on either side of the car - they are held on with two ten mil bolts, loosen them on each side, and shove a quarter in, retighten
the car will run quieter and smoother
That's some interesting stuff - I assume you mean shove it a quarter inch in? what is an ASV?
sorry, did not realize you were intl - don't know what your emissions stuff isHeh, quite allright - I don't think we even have emissions testing, just as long as the thing doesn't create a black line visible from space that marks your daily commute
-
EGR? ASV? :S might need explanations of what these are...
how about brakes?
cheers

Hi folks,
What vaccuum lines on the EA82 intake manifold can I afford to dump? there's a lot of stuff running all over the place. This is on a HiCrappy-carbed EA82.
Also, does anyone know where I can find a service manual for the carb'd EA82? pref. a PDF download or something along those lines.
Cheers
-
also, does anyone have a ballpark figure for the kind of horsepower a mod like this could add, if I were to use the stock hicrappy carbs?
-
hmmm... any idea where I could get my hands on such a tool, or how I could make one myself?
-
forgot about the search, sorry :/
I don't think it actually has a center diff...

Hi folks,
I'm planning on converting my EA82 to RWD only. Down here we don't get snow, so the pavement's dry all the time
In any case, RWD (Right Wheel Drive) generally drives a helluvalot nicer than FWD (Wrong Wheel Drive).
So the question I have is this: the tranny is a D/R 4wd 5-spd. Can I take out the front driveshafts and run it in 4WD permanently, thus making it RWD? will it be rugged enough to survive, say, if I were to stall the engine from high revs?
I'll probably be modifying the 4WD selector lever also to make it so it can't be put back into FWD (otherwise I'll lose power
), and unplug/remove the 4WD dash indicator light, and just leave the low ratio light (I still want the D/R feature! )what do you folks think?
-
Ah, I got some for ya
got them in the process of trying to figure out how to do the dual-carb setup.They're not very clear, but here ya go
-
Doubt you're gonna find someone with pre drawn plans tho...... You might have to get the vernier out!
Oh hell, with my in-chiropractic-progress back? gonna be murder
very interesting thing just came to mind. At university, we have a machine that can "print" 3D shapes. Forgot what they call it, but you can basically create a 3D object straight out of Solidworks. ABS plastic. Hmm, anyone up for a plastic manifold?
:grin: -
from taking off the manifold yesterday I saw the port in the head is pretty much adequate to feed the cylinders. Remember, only one cylinder at a time will be sucking through that hole, and unless you get some radical new cams, that hole will pretty much be sufficient.
The hole itself is about 1" to 1.5" in diameter at a guess. However, the main barrel of the Hicrappy carb is 0.75" or so - probably even less:banana: so in the end, the idea is to double-up the carb to allow the thing to run more freely - and on top of that, to just be able to say "I did this"
-
I've done a fair bit of digging around under the hood - if anyone can slide me a technical drawing of the EA82 (inc. heads) and the intake manifold's carb base then I think I'll be able to draw us up a plan for a manifold, incorporating coolant, vaccuum lines, inter-carb linkages etc.
this sound like a good plan to anyone?
-
LoL, wonder what'd happen if you took one of those rather massive Edelbrock carbs and shoved it on an EA82...
-
quick Q: is there anything wrong with having really long drive belts? Figured if I could somehow relocate the alternator way off to the side on the other side of the engine bay I'd be able to fit two carbs on there much easier someday.
Might need to make hood scoops for it though, they'll be moved out from under the "power bulge" on the hood and the "studs" on top might just hit the hood...
EDIT: heh, an EA82 cruising along with dual, actually effective, hood scoops... heh
-
heh, I might just still do it for kicks - just need to get the facilities, because right now it seems it's going to be too hard to make a pattern to build a new intake from.
Oh, another interesting note. Idle speed without airbox: 1700rpm. Idle speed with airbox and filter: 500rpm.......
-
Drat.
Just came back from a 2-hour greasemonkeying with the car - sad to say that putting two carbs on is pointless. The ports are the same size as the manifold vent, the only limiting factor is the carb throat.
Might as well just slap a big Weber on...

how about one of those high-flow cone filters?
