Hi my name Is Toby. I have a Yellow VH Commodore Wagon. You may have seen it at Wakefield park or Eastern Creek. I have slowly turned it into a ripper of a track car that leaves Porsches and Ferrari's in its wake. I have changed just about every thing on the outside of the motor. The crazy thing is that the Rb20 makes 386rwkw and has never had the rocker covers off. Nothing has been changed from the rocker covers to the sump. (ie Stock rod,pistons and cams). I have set the shiftlight to light up at 8300rpm. By the time i change gear it just brushes 8600rpm. The turbo is a bitza. 8 litre diesel compressor, RB20 ballbearing core and VG30 turbine housing. It was put together by Precision Turbo and runs 30lbs all the time. They high flowed the whole lot. They really know their stuff at Precision Turbo.

About two weeks ago I rolled my Commodore at turn five at Wakefield Park. I was in third gear with the tail out and I miss judged the apex op the corner. My front left wheel went over and off the ripple strip onto the dirt. As the wheel went back on to the ripple strip it caught me and flipped me over. I estimate that I was doing about 110km/h when I roled. I rolled 3 and a half times coming to rest on the drivers side. My roll cage, Harnesses and helmet saved my life!

Any way while the car is off the road I wanted to build a good engine for the car. I want to build a RB24. I have a RB26 head, RB25 block and my RB20 engine. I wanted to use the RB20 crank in the RB25 block with the RB26 head. Does any body know if this has been done before and if so what do I need to know. Are their any major hurdles or is it a simple bolt together afair?

Any how it is time to start pulling the old girl apart. I am building another wagon. This one will be even tougher.

      Because it is financially convenient for them lol. Why wouldn't they want to give you the lowest possible valuation for your car?

      Yep. @Duncan also shannons they will rip you dry and will be probably limited on how much you can drive. Also keep in mind that you always have to have it garaged with Shannons, with enthusiasts as per their PDS you can have it 2 times per week on the driveway for example.

      I had a generic 4" Varex rear box on my old V8, worked a treat for sneaking home late at night, it was as quite as stock when closed The car was "fairly" loud when open as it consisted of 1" 7/8 headers to 3" catted Y pipe, to 4" single, it did have a resonator in the mid pipe and only the Varex out the back I also hard wired in a Varex dash mount switch, as the key fob thing is a pain to use when driving I wouldn't recommend giving the beans when it is closed though as it creates a large restriction in the exhaust  It also can in very handy when pulled over for "random" breath tests or just cruising past the constabulary

      How To Fix Tacho, R33 (maybe)

      By stewart1 · Posted

      Here is the before and after of the scraping/sanding of the IC pads on the tachometer board for the fix mentioned in this thread. And yes it worked fine after. Just a note if you change any components on the board the tach calibration can be wrong showing the wrong idle etc...only problem is once it is installed back in the cluster you can't get to it to adjust...ouch! My fix was to cut out the calibration pot (the blue one) from the board and run it with two wires to the fuse panel under the dash where I could adjust the idle calibration once everything was installed. And yes I soldered everything up again including the half soldered components either side of the IC in my photos
