Welded diff

BB4lude · 24th January 2007, 06:53 PM

Has anyone here ever welded their diff in a fwd particualary a prelude?? just wondering how bad it was and what it was like round corners ie for track work did it just sledge off or pull round?? or run a otherwise locked box need traction for drags and track work but dont like the lsd prices lol and il prob need a new box soonish anyhow its at 170km now and been thrashed. btw is a rebuild worth it in a gearbox and whats a lsd box worth these days their damn hard to find
cheers ben
ps talking track not street here so please dont flame to much

Dont do it

Save the dosh for a rebuild and an aftermarket LSd ... cos factory LSD probably wont be too happy with anything like a turbo or something

I had one in my old civic (for track, hill climbs, etc). Awesome for hill climbs, Ok for track, crap for motorkahnas or anything that requires turning at slow speed.

BB4lude · 24th January 2007, 08:06 PM

LSD starts at 1800bux... and yeah its turbo but not massive power so dont need anything extreme at this stage and thats before installing and gearbox rebuild.... so not real keen on spending that much gota save for a house more importantly . do you mean tarmac hill climbs frost?? because i love the twisty stuff but dont wanna have to switch diffs between drags and hill work... . and i could always switch the welded one out for a lsd later if it doesnt work out
cheers ben

Yeah - tarmac. Don't have any vids from that car - but raced Hiwi Rd in it once. There's a link to the vid of Hiwi Rd in my build thread. Different car but obviously same rd. This was more of a bentsprint than a hillclimb, but the locked diff was just as good. Plenty of grip to pull you round the corners :thumbsup:

BB4lude · 25th January 2007, 01:34 PM

cheers frost good to have some info from someone whos tryed it instead off just assuming things . did you go through any axles ?? wicked build btw must go nuts il try watch the video dont rate my chances out here in the wops tho lol
cheers ben

Good old Hiwi Road again Frost :wink:

Next time that is on can you pm me about it?

d16a7 · 25th January 2007, 01:47 PM

you wont go through any axels.. if you do then thats Good going !

youl shit the outer CV's and it will only happen at full lock under power coming out of corners... soo just ease on the gas ... or dont go as full lock...

All i can say is.. hairpins with a locker will be interesting... i mean sure itd possibly be better than single spinner .. but there are ways around this.. i know a guy with his track car Never had LSD and still kept up with all the guys with LSD... its all about knowing how to use the throttle... if you want to Go for it.. but id personally do it once.. do it right...

No didn't break any axles. I agree with d16a7 also! The original track at taupo - the hairpin on it - that made some awful noises if you tried to give it hell through there, so just has to ease it around. :wink:

Yeah no worries Kane - I'll give you a message when it's on again.

Trench_Rat · 25th January 2007, 05:39 PM

locked diffs are great fun a guy i know had a locker in his old fgxt circuit car , you could throw that hting sideways at 100 and drive sideways down the road 8O

BB4lude · 25th January 2007, 06:19 PM

I think il give it a go and if its to nasty il order a lsd and just have to switch them out. gota get the damn gearbox out yet the lower arms seized onto the hubs sorta cant get it off not much fun on axle stands... . what diff do you run in your current civic frost??

Have an LSD now. Don't know what sort it is. Was supposed to fit but wouldn't - so we MADE IT FIT!!

BB4lude · 25th January 2007, 07:16 PM

"If it dosnt fit force it..."

. where did you get it from and how much any problems otherwise? the obx ones did have alot of problems but seem to have sorted them out and way cheaper than others but at the end off the day their just copys and you get what you pay for so not sure if their worth the risk.

Got it from speedfactor - but it sat in a box for a year before we got round to fitting it. Can't remember how much it was now. I'll check with the old man tomorrow and see if he remembers. It's been great! No problems - after the initial one. There's a pic of it in the build thread (somewhere) - but I don't think it has any names on it...

BB4lude · 26th January 2007, 02:20 PM

Well ive decided not to waste time trying it and ive ordered an obx lsd from the states way cheaper to the others they are just a copy and did have problems to start with but they seem to have sorted them out now so i think its worth a try il get a gearbox rebuilder to fit it and retorque the bolts like many ppl do with them. i wonder if yours is obx frost?? they did have problems with fitment at one stage seem to have sorted them tho.... hope so anyway

. does anyone know what a rebuild costs on average? and how much it would be to get a new 1st 2nd and possibly 3rd gear?? as their the ones that will take the stress so should get it sorted now as engines pretty much done for the moment just want to switch to twin coils soon.
cheers ben

Ive got a welded diff in my production saloon DA6, Its a pain in the ass to try and move around in tight spaces, chews out cv joints pretty quickly but is the best mod ive done to the car, on the track i can throw the car into corners and it powers out very well, much more predictable then what it was beforehand.

Macros · 26th January 2007, 03:53 PM

Wouldn't do it to a street car.

Mate has a welded diff in his race mini.
Gibson motorsport had a locked diff in their FWD sentra race car.
