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

      What should I do next to hold the head on

      By Gareth87 · Posted

      I can see between the water jacket and cyl 3 there wasn't a hard line of combustion gas. It certainly appears that the issue is coming from there. Yes, checked the tension. All at 100ft lbs where I set them 5 years ago. These blocks can crack but generally when they have been over bored. Mine is only 0.5mm oversize at 89.5mm. They break between cylinders around the 91mm mark. No sign of that with mine. My gut feeling is the head gasket lifted a while back when the studs stretched and i bandaided it by retorquing the studs. It's finally let go.

      So, version 4 intake is on its way I was looking at these a while ago but at around $200 or more it was a little pricey for something that might not work, but, I had it in my watch list, but, I got a message saying it was on special, and I had a code thingie to use, it eventually came in at $120 delivered, so BAM, BUY NOW.....LOL I'll need to have a look when it arrives but I feel it will "look" better than what I currently have, as it comes with a PCV fitting, so I will be able to get rid of the alloy pipe that goes to the throttle body with the PCV fitting  Well, that's what the voices in my head are telling me  Oh, and this happened today Yeap, it was a Trojan, and it was cheap, so I headed back to the hardware store and actually spent a little bit more on a heavy duty,  one that was actually recommended by a plumber mate, a Cyclone one with a fibreglass handle that is actually rated for clay The broken shovel will eventually be "modified" into a short handle shovel
