Getting ready to put all my bits I have collected over the last 6 months on -

they include -

RB20 Power FC

GTR 440cc injectors and resistor pack

Stainless Steel exhaust manifold

Maybe GTR cams later on $$ permitting

Due to my turbo being a bit of a mystery (told is was a 2510, but looks to be either 2530/35/40 but due to tag no matching up no one know) All I know is it makes dead on 200rwkw at 0.9bar and comes on boost at about 4-4500rpm

I am hoping for a conservative 220rwkw, running around 18psi boost, maybe 230 with a splash of toluene for dyno days etc

I am usure weather to use the stock AFM, or upgrade to a Z32 unit, as thelast thing I want is to get it all running on the dyno and find out that the AFM is maxed out...........

Whats everyones opinion? I have read post from Sydneykid that says it should be good for 226rwkw

Has anyone else made around that power with the stock AFM, as if its doesn't need replacing, I won't bother!

:D Chris

Yeah was thinking that myself, cheers.

I know Clint made 235rwkw with the RB20 AFM, but I guess with the Z32, there will be more 'resolution' so to speak

so you still have to run the AFM with a PFC then, its a shame you didn't get a ecu that did away with the AFM and kill 2 birds with one buy...good luck with it all..

Well my original plan was to run a Microtech, but I managed to pick up the PFC for a very reasonable price, so I went with that. Wolf3D crossed my mind, but a tuner I spoke to that would be the one having to tune it reckons they where best left alone........

Plus its plug and play, if I get defected etc I can jsut plug the old computer back in and change a few things

I don't think the AFM poses much of a problem/restriction at these type of power levels

      Maybe also really stiffly sprung track cars. Get the inside wheel up in a corner and all the fun stops. Also me sometimes (rarely) when I have to stand on the brake to convince the diff to drive the wheel that is still on the ground when I'm trying to diagonally get over severe driveway entrance, etc.

      R33 Fuel Pump & Brakes after alarm swap

      I feel like I'm missing something. You had an authorised installer come out and install a new alarm. Post install the car doesn't start, and you aren't getting the installer back to fix what they did wrong?

      So either way it is gearbox out and look what is wrong?  I know about the input shaft bearing. Even before swap/new clutch the it sounded exactly like this: So is that inout shaft bearing or the other was installed backwards?  And can some please tell me the part number for that input shaft bearing? The gearbox is small box from R34 N/A and number is FS5W71C. Thank you

      I am yet to see anyone ever regret a quaife or helical. ...other than drifting/skidpan duties. I kind of want to upgrade my factory helical with a Quaife (but really it's not ultimately that different, and is a MASSIVE UNDERTAKING), that's how good the hype is about them, that I want to try them 'just to see'

      D2 and Ksport are essentially the same thing and basically just generic Taiwanese manufacture. Better than ChinaBay crap, but... not top shelf. Öhlins have got to be some of the best dampers around, so likely to be a good option. It's going to get to the point though where I suggest you buy from Oz. We have at least 2x excellent options here. If I were you though, I'd be talking to KW about doing something for the R33. There's bugger all difference between that and the 32. In GTR land, anyway.
