Hey guys I need some help from some fellow members I’m in the next stage of my build and that’s suspension the car is my r32 four door but I need to lay the power down to the rear what suspension is every one running these days ?  Rang just jap talking to them they recomaned bc coils but I am open to options the car will be setup for drag racing the set up now is way to hard

First you need to fix the subframe.  The anti-squat geometry on R32s is the enemy of drag traction.

After you've replaced it with an S14 subframe, put a full set of adjustable arms into it and ensure that they are dialled in for minimal camber and as little bump steer as possible.  Then speak to MCA about some custom valved coilovers.

Yuh, but the subframe is essentially the same as the GTSt subframe.  The stuff that's bolted to it is not responsible for the geometry.

And the GTR diff isn't "stronger" than the GTSt diff.  Yeah, sure, it's a mechanical LSD, but then anyone dragging a non GTR is going to put a mech centre into the GTSt diff anyway.  And the 6 bolt axles are only marginally stronger than the 5 bolt.  So, go ahead and put that stuff in if you want to, but don't make the mistake of thinking that it's a major upgrade in terms of strength.  And do not make the mistake of thinking that the GTR subframe is better than the one that you have.

In the R33/4 and S14/5 cars, the suspension geometry was significantly improved over the R32 & S13 era cars.  And the S chassis cars don't have HICAS, which is worth getting rid of for any car, but certainly good to get rid of for drag.

agree with all above 

I dont know what power your going to run but I have personally run  high 500's hp with rb25 in both drift and circuit in r32 4 door with all of the above and have never had a problem with axles etc (I know drag is a little different with launches)

then if anything you can spend the same money getting s14 subframe + diif + below upgraded axles for a better outcome than circa $1000 - $1500 on the full rear GTR cradle

      Ticking Sound On Idle - Rb25

      By myrbgivesmeheadaches · Posted

      Thanks for the reply @GTSBoy this is is a hydraulic lifter engine. Yea right i did not realise the lifters were supposed to be compressible while installed. I could push them down but i had to lean almost my while body weight on them.  I have never heard of a lifter/ lifters ticking only at hot idle and getting worse the hotter it gets. I have owned a few jdm cars with noisy lifters. This noise is slightly more subtle, it is more of a sharp gentle metalic tic than the solid and more loud tapping I've heard on lifters. I have used a metal rod, alloy tube, hose and stethoscope and could not find the source of the tick. But it appears to be loudest on the actual engine block behind the exhaust cam gear and next to the oil filter. I had mate (40 year old mechanic) go over it with me and he couldn't find it either..  Could it be a cam seal issue of some sort?  Cheers

      Ticking Sound On Idle - Rb25

      By GTSBoy · Posted

      This seems problematic and unlikely at the same time. Vanilla RB2Xs have hydraulic lifters. They do have "zero" clearance, but only when running with oil pressure inside them. When not running, you should be able to compress them and obtain heaps of clearance. RB26s and Neos have solid lifters. They should have ~0.3mm and ~0.5mm on the inlet and exhaust respectively. If they have zero clearance then bad things are happening. With nothing else being wrong, it would mean that the valves would be held slightly (ever so slightly) open when they are supposed to be closed and it should have all sorts of problems when running, caused by leakage in/out through the valves. Or, zero clearance can indicate severe valve seat recession. None of it is good. Have you used a piece of hose as a stethoscope to try to localise the noise?

      Sorry for reviving an old post, but I'm having the same hot idle tick issue. Did anyone ever find out what it was?  I have checked/ replaced Injectors Coils checked Lifter clerance (is at zero) Checked Cam lobes Replaced exhaust gasket and studs Would appreciate any advice this is driving me nuts

      There's a huge reason manufacturers are tuning in dead flat torque curves... Make them reliable (and more drive able)

      What HVAC actuator is under the steering wheel? Do you mean on the RHS of the centre console, immediately to the left of your shin? If so, then yes, it is probably that one, because that is the mode door actuator, and from what I know, it's still a pain in the arse to replace. I don't know about whole dash out, but you certainly have to rip into the centre console section. I don't know if it's covered in the workshop manual, as I haven't spent much time looking at those parts of it. (and by "the workshop manual, I mean the R32 GTR one, which is the most comprehensive one we have, and it should be similar enough between that and later cars to serve as a guide).
