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

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.

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

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.

      They care about emissions, and cost the most. Save weight where possible, and make manufacturing easier. Less material also let's the engine transfer heat to water quicker, and bring the engine up to temp quicker, better for emissions and getting them past their warranty period.

      I was under the impression the reason why OEMs are going with solutions like relatively thin "right-sized" cylinder walls with technologies like PTWA and open deck is because they care a lot about whatever marginal knock margin benefits they get from that vs the structural rigidity benefits of a closed deck block and thicker cylinder walls. I also see some weird stuff like plastic inserts in the water jacket around the cylinders to try and equalize cylinder wall temperatures. re: the PRP blocks and heads at the end of the day it's hard to know what is and isn't going to work there, just have to see what the initial buyers say about it.

      Which is why I didn't mention that hardness testing, and specifically mentioned the bore and deck thickness testing. Yeah, not really. The bore temperature will be a lot more even around the top half inch or so, where the material distribution is dominated by the deck, and which is the only place where the bore surface temperature heating any gas in the cylinder is likely to have any effect on detonation. Think about it. Another inch or so down the bore, you might have a hotter spot. The gas there might get a bit hotter, then the piston rises squeezes that gas away from there at high speed and mixes it with other gas from nearby. Instant dilution of the problem. I'd be surprised if it was an issue at any time other than in racing engines or OEM dev engines being run at the ragged edge of tuning. Say what now?

      https://dsportmag.com/the-tech/education/engine-tech-material-hardness-testing/ The PRP testing on block hardness I'm not sure how much it actually can be trusted. The thinner cylinder walls on RBs is a bit of a problem vs 2JZ but it really depends on the design goal. Siamesed cylinder bores like a 2JZ cause uneven cylinder wall temps too, which means a bit of distortion induced by that + the hotspot can affect knock margin. Something that actually gives me a bit of pause with the PRP block, whether super thick cylinder walls are going to keep it from being drop-in compatible on an otherwise OEM rebuild.

      Yeah very valid point. I am waiting for one of the other tuners to come back from vacation so he can help me a bit when the cat is installed again. In the meantime I am going to finish up my polishing and ceramic coating that I have started myself.    N45 Dr Beasley product is highly recommended for a paint primer / polisher. Using this EXO Gtechniq also for the ceramic but next time might use the light serum before hand also. Looks great.
