What are you comparing the RB20 woth when you say more punchy/torquey. SR20?

You dont need to stroke it to go 2.2L, just overbore the engine, which means a lot of labour and new pistons so expensive if all your looking for is more torque.

If you want torque then a 2L turbo engine in a 1350kg car is perhaps not the right car to start with. That said you can do things like breathing mods, cam gears etc etc that all helps torque, or you can change the diff ratio to make the thing more punchy, but at the end if the day its a 2L engine...modern cars and technology sometimes spoil us rotten and we forget that we cant have everything.

But a good place to start is full exhaust, good filter and intake, cam gears apparantly work well, if you need a new clutch then only get as big as you need and go for a lightened flywheel at the same time, and throw a shorter diff ratio at it and lern to use those 7,500revs, and stay away from 18" chrome wheels.

Im probably wrong but thats the way i look at it

What are a few things that can be done to make the rb20det a bit more responsive. and have a bit more torque?  Like the sr20det...

How much would it cost all up to have it stroked to 2.2 or 2.3 ltr?  Would this be a good idea?

What mods do you have? If its relatively stock I'd try an ECU + dyno tune and a lighter flywheel.

well my 1st car was an r32gts4 and i wasnt too happy with power until about 3800rpm.

I then bought a 180sx.. it felt nicer at low rpm.. but for some reason i like the r32 so much more.. so ive sold the 180sx and now looking for a clean r32 again..

I want it set up for drift as much as possible which is why i want a more responsive engine...

I would love an rb25det r32 if anybody knows of one!

rb25 definitely.. if you can afford it..

i am "downgrading" to an rb20det for a while until i go for a monster engine. Will be interesting to feel the difference.

Have been in a couple of r32, and more nothing, then on.. rb25det is much nicer..

some of the better rb20det turbos are meant to spool up a bit lower and give much nicer response down low.. HKS2530 and things like that. You could research into those a bit more.

hi there,

there's a guy selling what seems to be a very nice R32 GTS-T with nice bits and pieces on it, so if you're interested, check this out;

      Looking for a part number for this part here

      By eli995 · Posted

      (Rb25det intake manifold) I’m having a hell of a time trying to find the full part or part number of this coolant hardline so far I was given these (Below) but they aren’t what I’m looking for and was told it’s the IAR or aac valve but that doesn’t seem to be it either. If someone could point me in the right direction it’d be greatly appreciated. Or if anyone has it for sale that’d be great too. I have recently purchased a greddy manifold and I can’t seem to find my old one to pull it off.  (Front Heater Return / Water Pipe (under intake): Primary part: 14053‑21U10 (front return pipe assembly for R33/R34 RB25DET) Alternative listing: 14053‑21U00 (same pipe, sometimes interchangeably referenced)   Heater Feed Pipe: Listed as 14075‑04U00 or feed-related variant 14053‑AG500)

      This sounds cool. But, as per usual, anything really complicated like that, that I take on, constitutes a steep learning curve that I never actually "learn". I just get it working, install it and start using it. Then, when it breaks a few months later, I've got no memory of what I did, how I did it, or even the bloody IP address I gave it. I'm having more or less exactly that problem right now. My Proxmox machine was discovered to be non-responsive, and the VMs on it were ditto. Power cycle it to a stream of loud Dell beep codes - which was unpopular at midnight, I can tell you. Move it to the lounge room so I can HDMI it to the TV for a screen, see the boot messages complaining about the /PVE/data having all sorts of LVM problems, saying it needs to be fixed manually. And I'm like....great. How am I going to work out what I need to do? At least it wasn't the stupid Silicon Power SSD shat itself. Mental note for all readers - DO NOT BUY SP SSDS! They are shit. I have had one take out an entire VM setup already, and this one could have done the same. Maybe it actually has. Cheap Chinesium shitbaskets. I won't cheap out again, even on play projects with no budget. Because my time budget having to fix shit is worth far more than the cost of proper parts.

      I do typically agree. These days even the screens most people use have more of a boot time than the main device. However, I've seen an interesting use of the RPi in vehicle, however it involves effectively building your own OS and MBR, as then it boots up exceptionally quickly, as you don't have everything needing to start up, and you can then also run it up as an RTOS, while still having more compute than an Android can give for things like display, and processing. A very huge task that would be though for Duncan, I'm not sure that's his skill set (or Arduino programming and wiring) ha ha. If end goal is definitely just water cooling, Arduino would be the simpler setup especially for a rookie. If he wants extra display stuff though, bashing some code in Python on an RPi may be the better result for both systems.   Unfortunately the new device I'm building at work which runs a display, is too slow of a display for dashboard style purposes. More extreme low power, update only a couple of times a day type system

      I don't like "actual computers" for in car use. They take time to boot up, have OS annoyances, and so on. Arduinos etc are ready to go a few seconds after power on, don't mind being agressively powere cycled, because everything is non-volatile, don't mind being shaken and stirred.

      As Fred would tell us, it's all about interpreting the rules. It's not a water sprayer, it's a water mister... But everything else you've said, 100%! Even a raspberry Pi would be great, use HDMI out for a display, and add a raspberry Pi CANBus hat to read values out from the ECU.
