st185 turn it to rwd by fuse?

[KwS]

No not true. Only skylines with the attesa 4WD can do this afaik.

Most subarus you can pull a fuse and make it 2wd... however it's FWD... nothing quite like a FWD tyre shredding WRX...

not saying it's a good thing, just nothing like it.

only if its auto afaik. The manual boxes dont use an electronic centre diff or anything. The autos use that fuse so you can safely tow the car or use a space saver.

north south engine in a car designed for east west = crap. Yeah, I said it

Unless the chassis is well reinforced to deal with the totally different stresses it sees, it's always going to twist to buggery with a torquey longitudinal motor if it wasn't designed to deal with it.

[thegreatestben]

Have you seen the project build on that st185 with the 1UZ.
You'd probably want to if you haven't already. Very impressive

Typical engineer thing to say. I did mechanical engineering and tbh, who cares. It would be one hell of a laugh/something different.

I think whoever has the intention of turning a EW engine into a NS one will look into that sort of information anyways let alone the certifiers who will look at the car to try and make it road worthy.

I'm not sure that many people that do such conversions give it much thought really. I know the 1UZ ST185 (which btw I do think is nicely done, with the exception of my thoughts above) had problems which may or may not have been fixed, where the hatch would sometimes pop open when the engine was highly loaded.

I personally wouldn't want a car that gave different handling characteristics depending on whether you were turning left or right, which is something you're likely to get if there's significant twisting from the engine applying loads to the chassis (under acceleration and the opposite under engine braking). It might be cool to cruise around in and probably goes alright at the drags, but that's not my cup of tea

Justens car ( the RWD 1uz St185 ) is sorted out , and going thru further handling , braking and power upgrades as we speak ..

Currently it has a better weight distribution than the AWD 3sgte version, is craploads faster , but like any powerful RWD car , will still kick the bum out easily when pushed and try to kill you..

Justen doesnt do things by halves, I can guarantee that. His workmanship in these sprt of respects is only matched by jamies IMHO:)

I think it's the autos only, Seems to be quite common for people to turn imprezas into rear drive drift machines

Not knocking his engineering ability, but I would have to think that unless he was able to substancially reduce the weight of the GT4 while increasing its regidity it would have to be slower around a track than a mildly worked stock GT4.

I'm not questioning his workmanship, I have no doubt he's done an excellent job of what he has done, it's more to do with the underlying weakness of a chassis designed to be loaded in a particular way but its engine being loaded completely differently and with considerably more force.

And since you brought it up, I'm curious as to how do you define "better" weight distribution?

[Trls250s]

1uz = better skids haha

Altho a Tim spec 3s is more then enough for any man....

[Prymal]

yes , ill be getting a tim spec 3s , and justens car will still be able to put it in its place .. Currently its being converted to more track car than street car as far as i know - you can follow his build over on toymods to see what hes up to..

Seriously , the car has been done properly , he has alot of very knowelegable people working with him for any specific advice he needs outside of what he already knows himself .

As for the second reply, The weight bias/distributions front to rear is better on his gt8 then a gt4 .. Overall weight is also less i believe than the other white ST185 group A he had , and that itself was a very fast car.

[Malcolm]

no, what I meant is - what defines better weight distribution? You can't just say it's "better". Does better mean more rear bias or less? And how do you know which of those options is the better one?

Been reading this thread and find it a rather intresting topic

I have personaly driven, a evo 1 converted to rwd, and a couple of wrx's converted to rwd, all of witch imo handled like ass, even more intresting is all cars had farily well set up suspension, wrx had ohlins coil overs, cusco say bars, evo had coil overs.

Converting a 4wd to rwd is not a good idea, as the often these cars were made 4wd to make up for a shit chassie, evo expecally

but then again, anythign can be created with right amount of fincal input, the jun drift evo 9/ 10 would be a prime example

Actually i havn't, but any four door family car, that is taken then converted into a high performance 4 door sedan, is never going to have a chassie as well desgined as a purpose built sports car

But then again, you seem to be a world of knowledge, going form what you have built and created

[barryogen]

must be taking the piss or wrong... I make nothing, just wondered which cars were known to have had this done to them, it seems to me that it would be cheaper to design the chassis correctly rather than redesigning the drivetrain and body layout to be 4wd.

whats being a very fast car got to do with weight distribution?

someone forgot to tell Audi that then. their cars have been designed around 4wd for years.
most of these cars all handle exactly like you would expect a 50:50 split 4wd to handle (except the st185s dodgy centre diff). mild understeer that can be adjusted to a balanced oversteeer if you throw the weight in enough.
they werent built just to make up numbers, they were built to compete in rallys, and as such the basic mechanical grip and handling even before you add fancy diffs and suspensions is usually pretty sound. its not in the manufacturers interest to just slap 4wd into whatever chassis and try make it a rally car.
the chassis themselves are often quite different anyway, they are usually strengthened with extra welds etc and different style suspension setups.

oh and making factory 4wd vehicle rwd = FAIL
kinda like the kids that tried endlessly to put the square peg into the round hole.

its OVERALL weight is less i believe - meaning the AWD group A was heaver but still very quick on the track

justens RWD one is lighter overall and will be lighter again soon - and horrendousy fast on the track .

hes had 2 group A's if that also helps clarify stuff.

Seriously though you guys have any technical questions , pop over to toymods and ask .. Both justen and jamie are fairly open to genuine enquiries and could explain and back up what the have done better than a third person like me .

As for the extra welding - ive seen this first hand when tinkering with my old group A replica - body Strength in the 185 seemed to be overengineered to the max , And i know my 205 group A is also equally as braced and welded .. I havent checked but it may also have some examples of the WRC car preps in there already , as friends in the UK have found extra support brackets and sections in their Group A/WRCS where as the jap spec ones havent got these bits..
