R33 Subframe in R32 GTS4/GTR problems

Hello all, 

I picked up a R33 rear subframe for my R32 GTS4 and was going to fit it to obtain wider track, better anti squat etc. 

What is the best way to mount the frame? Fit the offset aluminium bushes from the top down or from the bottom up? If they are fitted from the top down I'd have to get some sort of spacer to make up the difference as the 'pegs' that the frame mounts over dont have enough thread. 

I'm concerned that it may alter the geometry negatively if its mounted flush to the chassis rails not only will it be hard to mount the ATesa pumps etc. 

Has anyone done this? Or is it worth just changing the bushes in the standard frame..

Just a follow up,

the lower arms are different slightly, and the ‘nose’ of the diff sits in another type of carrier - different to the gtr/gts4 cradle. I will make 16mm aluminium spacers to fit the rear cradle into the car which will sit under the offset bushes. 

Im yet to cross the hurdle of mounting the attessa pump and ancillary parts

      Blue/grey smoke after idle

      Update Got turbo back from hypergear, installed everything etc. Bled coolant, wasn't smoking so I thought beauty she's sorted now. Went on a drive, car up to temp, let it idle for about 15 seconds, gave it some gas...nice puff of smoke again. Fml No doubt my turbo was pretty worn anyway but nonetheless frustrating that the problem persists.

      Lol, yeh sure. But I'm not changing the head on this engine. Turbo is the current mod im looking at; as the VCT-2.6L  engine im building is getting the turbo setup i posted so the old built RB25DE needs a snail

      New setup just needs a VCT enabled head and it will come on so much earlier. At least 500rpm of added response, if not more.

      Question about BoV on RB25DET NEO

      By MBS206 · Posted

      Something to note, on an aftermarket BOV, it's quite possible to end up with the worst of both worlds, where on light throttle, there isn't enough force to open the BOV so you get small reversion and driveability issues, and with the venting to atmosphere, it dumps a lot of fuel on shifts. Realistically, dumping to atmosphere under power isn't a major driveability issues, compared to the issues of stalling from reversion. If you're getting up the throttle, then putting the clutch in, say on a shift up, but then don't release the clutch, yes, the engine can and will stall, but, just drive around it, and that's easy, let the clutch out in the next gear and the car rolling will keep it all running / going.who wants a hard hit of throttle and then to just let the motor idle anyway?   Main issue for driveability is blipping throttle and it wanting to stall, like when parking or trying to move in slow traffic.
