Kinda weird it has a big boi box

seeing i took us to RFB world I'll spam your thread for a sec as I've been on a similar journey of study albeit slightly different goal I am gathering up last of parts now to see if i can simply stroke an rb20det (78mm piston 69.7mm stroke) by using a rb26dett crank (73.7mm stroke) - will have some stock rods next week so I'll put it together and see physically if the theoretical maths works, hoping to be able to make it work without needing to make use of aftermarket (expensive) shorter stroker rods (119.5 vs 121.5mm). Maths says with a slightly thicker head gasket I can still get around 9:1 static CR. Potential to bore block to say 80mm (could go further) as its probably going to need something anyway being a thrashed twenny debt. Main reason for looking at this is I too love teh rpms but an rb20 is not really setting the world alight power wise and while it will happily take boost it means that power will hit like a train at ~4000rpms and off boost power is a bit shit - i want it to behave kinda nicely as a road car. So I am kind of going the opposite direction on rod ratio but trying not to drop rpm too much, RR goes from 1.74 in a rb20 to 1.64 in an rb26 but i am hoping that in keeping the stock (or stockish) pistons it will be light enough that forces are low in the higher rev range, not shooting for 10k though. One of the big constraints for an rb20det is head flow, In the car right now is a redtop rb20 which basically has TVIS (NICS), I will grab a more common R32 silver top head and I am currently looking at an R34 rb20de neo head as well (which has massive intake ports by comparison, and VCT on intake cam and has its own TVIS kinda thing but likely not used for boosted applications, not sure valves are any bigger yet which is constrained with tiny bores at 78mm - online data is weak so I will measure - I also need to cc the combustion chamber of the head as I cant find if its any different to a 20det, if its less then this will create more of a headache for CR) /RB the world //650 woulda got you 2 barra engines ///I was pipedreaming future track cars and was looking at 2AR and 2GR engines a while back (2AR inspired by your 1NZ work) I feel my pipedream is endorsed by your research and action lol ////ling out - I'll post up my stz in my thread once I have some actual measurements and a direction

same done between rb25 and rb26 re piston wrist pin (rods same length, pistons same bore, stroke slightly different) - pretty common practice between engine family variants i think

All good, keen to see in that engine bay of the CET p10 primera Steven Richards peddled, I see the P11 has a flipped head as per most of the later 90s touring cars Sorry for touring car chat invading your thread romandayf I did like the Volvo, I think it was, that was also using the same location either side of main intake to take ducts down, presumably to other oil/water coolers/brakes Who was talking about low intakes? Speeno? All of these seem to sit high

lush, did you snap pics of all the cars too? would be cool to associate engine bay to particular gen/class of touring car

lush did you rebuild? I dug out a couple of frames the other day that i never got round to finishing when i did my supersport for the original OS bike meat, hmx500 and a standard girls raleigh 20"

Wow, I mean, I know how much you rated that BA

Does anyone have sauce on various engines factory cam specs? trying to find stock redtop/silvertop RB20det intake valve closing angle. /i could be annoying and ask kelfords edit: found via a bootleg manual http://www.turboninjas.com/supra/maft/8 - Vehicle Specific Info/R32 Nissan GTR/All Engine Manual (OCR).pdf

@mjrstar what did you do with the CD009 bellhousing?

Sr20 not that bad?

with your top speed target in mind, has rolling diameter changed a lot from what you ran last time?

SR20 for ease/availability

Fairly sure I'll have some parcel speakers for the rear that could be of interest, ill rummage in garage tomorrow and let you know what I have Other option is just do some 6x9s (i assume they still make these) and build a speaker box for them from mdf and carpet them (this what we used to do at highschool)

ah yes, now I see it

Few skid demons around id say, not just in grease mud

dunno why but @sentras grubby hivis rainjacket ticks all the boxes

Sorry that was directed @kiwi808

Do you mean iPad pro? I didn't think there was all that much between a air and regular except one is thinner/lighter, screen a bit different and they get slightly different processor specs depending on release date

Imo air not worth it for mum, my mum and nana are both on many years old iPads perfect for as you describe

it was deep man, talking about a toyota echo, talking about how it sounds, and quoting/repeating like an echo echoception

im just gunna say of all threads im dissappointed this pun didnt take off

very cool echo this, so hot

Chur, had z31 vg30s in mind I've had grit/crap/whatever get stuck in vvti actuators before which messed with timing and idle revs as was getting stuck, could be worth whipping them out for a flush/clean Symptoms were high/slightly tough idle like unmetered air was getting by. I fucked around with IACs for so long before seeing it was a timing/vvti issue This was in an auto and would require heavy breaking at rest to resist rolling fwd as it was loading the torque converter

Theres no vct on these right?
