Hey guys, mate and I that both own 32s running RB20DETs are in the dilemma of deciding where we'd like out of our cars power wise. Neither of us have been in an RB20 with anything other than the standard turbo so we're wondering if there are any friendly member with a powerful 20 who wouldn't mind taking us for a bit of a spin so we can get an idea of what we can expect. Will shout a beer!

Well we more wanna get an idea of what to expect of X amount. We haven't really set a budget yet and don't really know how much power we'd like because we're not really sure how much we'd like. We've both done full exhausts, fmic and the basics and are now looking at turbo, injectors, AFM and tune. I've already got a Power FC so we just wanna get an idea of what we'd like. Anyone mind sheading some light?

So what are your choices? Power or new car? For turbo, injectors, AFM and tune, youd be looking at around 4000, thats the minimum. Theres alot of extra unexpected costs as well, as im sure alot of other members will vouch for|!

hey mate, atm iv got a

vg30 turbo- $300 and all the usual..eg fmic, fuel pump, bleeder valve, and a re-map and also an external gate (not nessisary but sounds damn good lol) and iv got 215kw at the treads on 15psi, injectors are at max flow and yu shouldnt realy run over 14psi with vg/r33/standard turb obviously, so i wouldnt reccomend it but iv had this 4 over a year now and its all good! our customers cars we usualy run 14psi max in top end and get between 180 to 200 kw. cheep!

biulding a 3L now! :blush:

ive got just a bit over 200 killerwasps @ 14psi with a turbo from an rb25, standard piping to a fmic (standard piping to reduce lag) 3" turbo back zorst, gtr fuel pump, bleeder valve and a remap. got other toys too like coilies strut braces and a 2-way but they have little to do with power.. the only other things that i will do to this car will be stuff to keep it happy (like a big ass oil cooler, moar efficient radiator and a sexy oil catch can)

i want MOAR POWAAHHH, but i think that will end with me getting a new car

The VG30 turbo sucks. Its nothing more than an rb20det cartridge with slightly larger comp and turbine housings.

The rb25det turbo on the other hand has a similar sized exhaust housing but both a larger compressor and comp cover.

Definitely the rb25det turbo over the vg30det turbo.

Average power FTW.. It accelerates you quicker to that 200killawasps of where you only spend 1/10th of a second anyway. :P

Unless the car is a track hack I wouldn't bother spending money on the rb20. Drop a rb25det in to it and make 2x the power with more off boost acceleration, more mid range, considerably faster spool and just so much nicer to drive.

Or you could go the rb30det and spool a larger 525hp rated turbo the same as an rb25det spools its stock turbo. ;)

As for how much power... 200kw is quite lazy. 250rwkw+ is repeatedly 'fun' in a r32 gtst lightweight.

250rwkw as a streeter with an rb20 will no doubt have you loosing your license as it will require you to ring its neck to 'feel' fast.

RB25DET or greater. :P

We'd def like to consider the 25 / 30 option but legalities would make that less feisable and we don't really want to be driving round cars that insurance would void (especially me as the 32 is my daily).

Go the RB25det then.

Regardless; suspension, highflow turbo, boost controller, remapped or aftermarket ecu are all insurance voiders if they were to get nit picky. :P

When listing mods with an insurance company and they say yeah thats fine.. The fine print also states it must be legal.

I see your logic. We'd still like to go for a small drive in something (be it 20, 25 or 30) to get an idea. :P

if you decide to stay with an RB20 you're best bang for buck would be the 2530. fast spool, reliable power, low mounted, fits factory manifold and dump. probably the best turbo built for the RB20.

have a read of the RB20 upgrade thread as it may give you a heads up on what parts and costs are involved in getting to the power figure you want.

ive gone a lil stupid on my rb20. ive spent over 10k on parts from october last year until now on a stock internal motor. you really need to decide how much you want to spend then you can decide how much power/driveability you want to achieve.

+1 for the 2530

once ive finished wiring the loom for my mates 300rwkw R31 with a 20 in it im sure he wont mind me taking you guys for a drive! hehe.

Sounds good, that's what we're after.

give me some cash an your rb20 and i'll think about giving you my 255rwkw RB30DET. (All the works done, haha!)

Sounds exciting, how much are you asking?

I'd probably be looking to budget aroud 2 -3k depending which turbo ect but I will also be looking into the budget options like 25 turbo and saving my cash for another car or RB30 conversion.

I'm pretty sure my mate is willing to spend more than I am so I gues 3 - 5k maybe.

    • Just wanted to pop in an update on my setup. The CD swap has been great, I love the mazworks housing for the overall simplicity. I ended up sealing my trans tunnel with a thin sheet of aluminum reused some of the holes on the trans tunnel, and laid some window sealing EPS foam around the edges. Works great, really quieted things down and sealed up the car.  As for the power comment. Right now I am also running about 650whp. with the way the bell housing is attached to the face of the transmission I have zero doubts it would be fine, mainly because the input shaft and main shaft bearings are seated into the bell housing adapter. This means the load is NOT on the bolts to maintain the power, rather into he casing of the bell housing; Yes the bolts are doing some work there, but with both shafts locked in zero worries.  End of the day, the Mazworks solution is the easiest and safest. no need to take your trans to a shop to get milled perfectly, it fits with minimal clearancing, and you can use all your existing clutch and flywheel.  Driving wise the CD has been great compared to the big box, I'll probably swap my final drive at some point. The serial 9 shifter is gooooood, my only qualm is how tight it is, it takes a fair bit to get use to, 5th and 6th are a bit eh/hard to find at times, but maybe I need re-adjusting, and I think my clutch master is very tired and needs a rebuild. 
    • If you are keen, have a look at my build thread. Car is for sale for the right money or straight swap for a F80 M3 LCI.
    • Welcome mate.  No point in over thinking it, buying any one of those cars you mentioned is not a smart or logical choice with the availability of many "better" (re price to performance) cars available to you.  The heart wants what the heart wants, buy whatever it leads you too.
    • Hey everyone! Im so grateful to be apart of this community and ill do my best to be apart of this. Firstly, i'm not disclosing my real name due to in real life circumstances surrounding my privacy and public image (sorry lol) Secondly, The only thing personal I am willing to share is that I'm from Sydney and a descendant of one of Sydneys largest mortgage firms. I got gifted my first ever car, a 2022 Porsche Cayenne and I love it to death. Ive been driving it for about 5 or 6 months now and honestly Im so grateful for my parents for gifting me this vehicle. However recently I've been working my ass off to afford my second car (which I need help deciding soooooo community help me out please?). Once decided, im planning to try modify it myself. Recent I've been thinking about getting a Skyline, particularly a 25GT or GT-V, yes I know overrated as hell, but I'm also considering a Chaser which I recently came to love. However my dream is to one day own a 180SX (So hard to find clean versions and im not really into importing).  Lastly before I send this off, I want to apologize if I sound tacky or pretentious. I try not to and want to genuinely learn from everyone and anyone. (Im no expert in this area) Thanks for reading!
