no hate cos altezzas are a guilty pleasure, but what is a period correct altezza build? And do you need help choosing your sex spec livery?

Clint loves RBs Beaver they're his favorite demographic

is the same engine family but bigger capacity block and head considered a swap? is there a granddads axe scenario. Its the same crankshaft the rest is just modified. or do i need to concern myself with trojan sea horses
-
the cap is suspicious cos with all these maxpeeding rods (and all the others that look exactly the same) the have this cut which feels like a stress multiplier. i dunno what breaking the cap first would do though, would it eventually just break off and flyaround leaving the rod and piston just stuck further up the hole rather than tearing the rod in half?
-
Eek, that looks puckery But I was so convinced they were genuine arp2000 rod bolts How many shifts had that donk done ok the dyno?

That's a pretty neat find, what's the rod length now? Oh lol did you edit that in or did I just not finish reading -
re cross sectional area, ive only just started looking deeper for n/a and i dont have my head around yet but there seems to be a trade off between cross sectional area (based on more area for more volume flow rate in general) and keeping small enough to maintain a high enough velocity/intake momentum for high rpm/short stroke (where rod ratio also comes in due to movement, or lack of, at BDC for example when cylinder filling) Im probably not explaining well cos i dont understand fully yet, im sure others will know theory+real world better than me

That looks like the solder rig I just received from aliex -
"stumpy" is what its known as and is a 71b trans variant, google ai reckons its too weak for your aj6 torque
-
Looking again at your pics you need something with shifter quite far forward? Iirc there was a 'stubby' box maybe for a d21 that was a 71c?
-
Yeah big box is a normal swap for a rb25+t/comes normally on the rb25det, they are pretty stout, again more than what I'd guess you need (smol vs big below)
-
/just saw your tunnel pic, i very much doubt a cd009 is fitting in there. i can grab some dimensions of RB box if you want but internet should be able to provide
-
I'd have thought a t5 would be fine? what about a nissan small box, Fs5w71c (rp71c) from a rb20/rb25? they arent too pricey, nice and light and are fine behind an N/A RB25. they last ok with 20dets with the wick turned up (until they strip 3rd lol)
-
not used but its my current plan for rb build, supposedly t56/tr6060 equivalent in stock form so yeah pretty strong, they take abuse from drift spec VQs errday I'd say its stronger than you need, they arent small either
-
Lol i was meaning for me but sure These are the ones I have, but I need to get an alignment done and current measurements before deciding if I actually need these or not
-
What about wedge shaped shims for twist beam rear camber/toe correction?
-
Ooh tomei rb powah secret sauce
-
That doesn't stop the rabbitholes
-
That compression ratio equation caught me out on destroke too on the rb, I can recover enough by going to 87mm...of course it was after I bought the 86.5mm pistons, thankfully I got them for a steal comparatively. So using the scanner you can cc the head combustion chamber easily?
