Roy Posted May 7, 2006 Share Posted May 7, 2006 Can someone actually get the owner or mechanics on that car to post here that it IS a stock bottom end???? And if so what is the catch? And would love to know more about that RB20 dog box Link to comment https://www.sau.com.au/forums/topic/116489-quick-question-whats-the-max-power-in-one-in-aust/page/2/#findComment-2145743 Share on other sites More sharing options...
1400r Posted May 7, 2006 Author Share Posted May 7, 2006 dog box might be up for sale Roy once the "lay shaft"(bit beyond my knowledge sorry) is fixed. From what I understand the stock lay shaft was retained to keep the box quiet but it meant that it would break every now and then savage rises in torque and power will do that the box is at ppg getting this replaced I believe stock bottom end my arse hat Link to comment https://www.sau.com.au/forums/topic/116489-quick-question-whats-the-max-power-in-one-in-aust/page/2/#findComment-2145766 Share on other sites More sharing options...
AzzurrA Posted May 7, 2006 Share Posted May 7, 2006 could quite possibly be a stock bottom end... (oh, and by the way, lots of people are starting to count forgies etc as 'stock' bottom ends) hardcore love their bottle fed babies Link to comment https://www.sau.com.au/forums/topic/116489-quick-question-whats-the-max-power-in-one-in-aust/page/2/#findComment-2145774 Share on other sites More sharing options...
Cubes Posted May 7, 2006 Share Posted May 7, 2006 1400r, unsure if its your mates or not. A couple of days ago Shaun (Boostworx) had an rb20 with a t88 strapped on the side of it. Made around 346rwkw? Hows it boost in the first 2 gears? None the less thats a rather impressive figure.

Roy Posted May 7, 2006 Share Posted May 7, 2006 Having recently looked at some RB20 rods, they look to be strong things. The pistons, well who knows how strong they are, if car is tuned well and its not stressed for long durations???? The bearings will cop a beating, but again the piston speeds etc are relatively low because of the short storke ... i would not be surprised if its a freshened stock bottom end?!?!?! If i can get an answer on piston sizes i have given myself a $500 budget to build up my spare motor and see what power/revs the pin come sout of the grenade Link to comment https://www.sau.com.au/forums/topic/116489-quick-question-whats-the-max-power-in-one-in-aust/page/2/#findComment-2145810 Share on other sites More sharing options...
Cubes Posted May 7, 2006 Share Posted May 7, 2006 You will need those big arsed lumpy cams Roy. I'd be interested to see how this RB20 makes power, cams it runs and where power noses over.

RedDrifter Posted May 7, 2006 Share Posted May 7, 2006 When I blew my original rb20 up I took a good look at the rods and I would think they could probs take a fair beating and all. My 1st impression was "bloody hell they are short rods. I would think that the bottom end if new(or good nick) could take a close to 300rwks for quite some time. As long as there was no det and gas temps were kept down a bit. The 8.5 cr would help alot too. Of course this is just an opinion and I could be far from the mark. Oh well.

Cubes Posted May 7, 2006 Share Posted May 7, 2006 Still a little dumbfounded over the amount of power it made. Simply awesome. Any chance you can grab a dyno print out for us and post it up?
