Rb20 Vs Rb25


Recommended Posts

hi all first post....

So basically im after a R32 or R33 Gts-t. clean with low kms, minor-no mods.

I have previously owned a 33 great car but i am leaning more towards a 32 this time around. basically i need some help in to deciding what car would be best suited (reliability, affordable etc)

these are some pros and cons ive researched between the 2 models. Can you guys give me a few not so obvious pros and cons?

RB25 Pros

Newer

Easier to attain more power in it's stock internal form

N-VCT (Nissan Variable Cam Timing)

Beefier Tranny

Better head design than the 20

Stroker kits available

More torque

RB25 Cons

More expensive

Lame Turbo (Better than the 20 though)

7,000ish Redline

Weak piston ring lands

Harder to tune than the RB20

Side Feed Injectors

RB20DET Pros

8,000 Redline

Cheaper

Easier to tune than the RB25

RB20DET Cons

Head doesn't flow as well as we would like

Lame turbo

No N-VCT

Harder to get more power in stock internal form

Weaker tranny than the RB25

Older

Makes almost the same HP as a SR20DET out of the box

270CC injectors (stock)

sounds like you made your mind up yourself ! buy an r32 with a 25 in it to save you the trouble

I love the look of the 32 but i want a decent 'all-round' car that ticks most of the boxes. thanks for the reply mate

Also realistically “low” km cars don’t exist unless you have full & authenticated service history. It’s 2012 – No standard issue R33 from ‘95/’96 is going to have 70,000km’s on it. 99% of them have simply been wound back.

R33 Chassis is better than a R32 one either way. They are a better built car, evident by the extra weight as well of course.

Also remember that Nissan electrics aren’t the best once they get older. So things like CAS, AFM, Dash & general gremlins creep in. Not everyone suffers but it can happen.

It doesn’t sound like your about to go through a 350rwkw rebuild, so just get as later model of R33 as possible – simply reduce the chance of headaches.

Doesn't it all just come down to money then mate?,most people I know would go the 25 and myself to if the funds were in the bank. Dont get me wrong i love my 20 and it does take a bashing and still is living happy but the 25 is just a bigger newer engine, flows better and can make more power with minimal mods...seems to me then ur only dilemma is the body, a nice sexy looking 32 or a hideous 33 rolleyes.gif .Good luck with u choice.

Well im heading back to uni so money is a factor. but i want something quick and reliable (being a 20y.o car that may be a bit difficult lol)

At the moment im keeping my options open, but still wanting advice/opinions from people who have owner either or both cars.

Cheers

i love the 20 in my 32 but when it carks it i will put in either a 25 or 25/30 (plenty of parts at my disposal) as there is heaps of parts available for the later motor, ive even considered a 25 neo(the STOCK one in my 34 goes like hell)

    • Slap a 460L into the car, send its mum.  
    • So last night pulling away from the lights, I lost power for about 1 second. Bit weird, but I kept driving... 5 minutes later the pump completely dies. When I tried to start the car, the pump won't even prime.  I left the car for about an hour, tried to start it and it all appeared fine. Pump primed, car started, got the fuel pressure I should have.... Start driving home, 5 minutes later it dies again. I'm stuck in a shit spot this time going up hill with a car right behind me, so I just let the car continue to turn over while praying to the fuel pump gods. After about 2 minutes of turning the engine over, the fuel pump came back to life and I got home (only about another 5 min away).  So I've been digging around online, it seems like the 525 fuel pumps really don't like to be run at 100% all the time. I've found quite a few examples online of people killing their Walbro 525 pumps within about a year of usage when they are run without PWM.  So, my pump is an Aeroflow 525 (AF49-1057) and I've been running it at 100% without PWM. I'm thinking the Aeroflow 525 didn't like being run at 100% and has burnt itself up.  I really am sick of dealing with fuel pump issues, my current thoughts are -  1. Use a Walbro 450 and run it without PWM. It seems like these pumps hold up pretty well to being run at 100% all the time. I only make about 350kw and can't see me making any more power any time soon so this is probably a fine option.  2. Get a Walbro 525, run it with PWM. I know doing this will annoy me as I feel like with only 350kw, its extra expense that I don't "need" and I'll be thinking the whole time while setting it up that I should have gone with option 1. I know I'll be happy with this option when its setup and running, its only the initial setup frustration and cost as an issue.  3. Get a Walbro BKS1001 brushless pump. This is the fu*k it I'm already going PWM, might as well go full retard. This option just seems better in every way, with the only downside being cost. But I don't know much about this pump so I could be wrong.  Happy to get everyone's thoughts before I go digging around in the fuel tank again. 
    • Doing it this weekend. For sure this time. Thank you forum gods.  And im running map sensor now with the haltech. Still have the AFMs attached to the mushroom dome shaped air filter things
    • Actually, it is probably pretty legit. I mean, it's still woke feminazi bullshit academia, but you would have to agree that it is very likely that there would be a correlation between wanting a loud exhaust and scoring at the unpleasant end of the scales for dark triad personality traits. The fact that they found it didn't correlate with narcissism and only with psychopathy and sadism definitely shows that the loud exhaust thing is more of a "f**k you" than a "look at me", and I reckon that rings pretty close to most of the dickheads who take it to the extreme. Remember, this is correlation with tendency to be closer to one end of a personality trait scale than the other end. Of course someone who is at the literal opposite end of the psychopathy scale is going to be so considerate of others that they wouldn't even think about wanting to upset anyone with a loud exhaust. So the finding isn't that "you are a psychopath". Just that you score more towards that end of the scale than someone who doesn't like loud exhausts (on average, not necessarily even for specific individuals).
    • Blitz ER34 at some point hopefully, should be allowed in Gr3 if they do.
