Hello guys! I have r34 sedan wich came with rb20de in it. I swaped my engine and now I have est 300 hp .Unfortunetly I am stuck with stock open diff. Can anybody suggest wich cars locked diff will fit because I can't find parts in my area. I was only able to find one seller wich has this diff he doesn't know from wich car did this diff came from. It just says viscous lsd and and ratio 3.69 . If anybody can help to check will this diff fit my vehicle would be appreciated.

Have a look on the plate on your firewall and it will give the stock diff ratio for your car which I believe is 4.3 ...so  3.69 will be a lot taller - probably more than you want. 

A viscous diff will not be much different from an open diff especially if it is old. To make a worthwhile change you need a mechanical LSD (I presume you don't really want a "locked" or welded diff).

Whereabouts do you live? You may need to search further afield to get a suitable diff.

Thank you for your answer. Yes the ratio is 4.3. My mistake by saying locked diff I meant LSD. I live in europe under Russia. My country is called Georgia.

It is pretty old

Um, they're all pretty old.

 

The first diff you pictured is not even from a Skyline. It is probably not even an R200. If it has 6 bolt (not 5 bolt as previously described) flanges AND is viscous, then it is more than likely out of a Z32, and could be an R230.

It's just the wrong diff everywhere.

 

The Laurel diff you show looks to be near perfect - so long as it is an LSD. Do not consider one out of an S chassis - there will be things that you can't handle - the ratio will be very wrong, the stub axles will be wrong and you won't be able to swap them between a VLSD and an open diff (as they are not the same lengths).

 

And lastly - you asked for a "locked diff". What do you mean? Just any old LSD? Must be mechanical LSD? The reason I ask is that VLSDs are weak. They barely offer any LSD action when they are old and when presented with a lot of power. Not that 300HP is a lot of power, but I got rid of my VLSD at that power level because it would just open up under load.

So to be exact this car is my daily driver. I dont want to weld diff. Because I want to keep it comfortable and safe on high speed turns and etc . . All I want is to make 2 wheels speen while trying to drift. So you suggest that there is no point in investing in old VLSD right? I am really confused, than what will be solution in this situation.

My first tip is don't drift your daily.

My second tip, is, if you want to drift, then you need a 2-way mechanical LSD. A VLSD is a form of AIDS that you do not need or want.

You can buy a Nismo (or other brand) mech centre to put into your existing diff housing using the existing CW&P.

Yep. Nismo diff is the answer here. The N/A R34 GTT has the same "stuff" as a S15, or at least a S15 helical bolts into a R34 N/A perfectly.

Luckily, a lot of people drift S15's so options are plentiful.

      Rusty roof repair

      By Duncan · Posted

      Shit thing to find eh? I guess the big issue is that whatever "fix" you do now, it might slow the rust down but won't fix it. I just wanted to add that in no way is fixing sheet metal in 3 dimensions the place to start with welding....that is a pro only job because its too hard to work out where things should be, let alone doing a clean enough job that it can look OK and still be strong too.  I needed to get a new rear quarter panel on the GTR and it took a pro weeks to get the old one off cleanly, new one on in the right place and looking somewhat like it should have with most of the previous connecting panels in place. Gluing a couple of bits of metal together with a welder in the garage is doable, but that is totally different to doing panel  replacement

      first time swapping rb25det into r34

      By Duncan · Posted

      This seems to be a very popular swap since all the turbo skyline prices went through the roof! I'll let someone more familiar chime in, but I understand that yes you probably want to swap the loom in to swap out the auto TCM stuff. You should not assume everything just plugs in either, you need to check at least the ECU wiring diagram for any differences at the plug at the left headlight and probably the ones near the ECU that join the dash loom too

      first time swapping rb25det into r34

      By dingleberry · Posted

      hows it fellas, my first post here which seems crazy cos half the forums i read are like the same age as me haha. to make a long story short ive got an r34 sedan (rb25de neo auto) which im swapping to a s0/s1? rb25det, r33 big box and nismo gt pro lsd. i have the motor and gearbox all bolted up outside the car, old motor and trans out. i bought the motor with stock ecu and loom, do i switch over to that? or will it be easier to get a r34 manual ecu and keep the loom if thats even possible.  also engine mounts look different, anything else thats different or incompatible? cheers, hope this all makes sense Paddy

      SAUNSW - World Time Attack Challenge - 5 & 6 September

      By Keeper · Posted

      Plan on the day will be to park trackside. Depending on space availability we will try put a small shade tent and a few of the cars on top of the hill inside turn 3, this is an easy to get to parking area with views of Turn 2, Turn 3, Turn 4 and Turn 5 and limited other pieces of the view around the track. IMPORTANT NOTE! One consideration from previous years is from memory the trackside parking sells out before the admission tickets, for that reason I encourage anyone planning on coming to buy tickets for parking now via the official website; https://www.worldtimeattack.com/ The type of parking you are looking for is 2 Day Park & View (Access Around Venue) Vehicle Pass Only Please note this does not include admission to the event itself, remember to grab that also, and kids under 12 get in for free!
