you just said you rarely rev it past 3000rpm

why do you think it must be some torque monster down low? it's a 2 litre straight 6

you will get more torque down low fro ma 4 cylinder because the pistons are bigger, the trade off is that being a 6 cylinder it will rev higher and easier

sell your car now because you have no idea

Hey all,

I purchased my r32 only like a month or 2 ago.

The car feels very slow/sluggish until boost kicks in.

I get munched by little yaris/jazz/swifts etc... at the lights (just driving normally)

Boost on car does not kick in until atleast 4-4.5k!

Car has fair bit of work done to it.

CAI

Pod

FMIC

3" TBE

Pon cams

Cam gears

Bigger injectors

Better coilpacks

Z32 AFM

Upgraded fuel pump

Bigger turbo

Nistune ecu (can't remember if that's the correct name)

Few other bits.

I hardly ever floor/race my car as turbo lags and it drinks so much petrol... i'm a GRANNY driver! LOL.

However when i drive normally it's so slow/sluggish... all these cars just overtake me and the ones driving behind me get's frustrated that i'm so slow.

Car does not feel like a straight 6 down low in the rev unless turbo kicks in. Getting overtaken and beaten by 1.3L is a disgrace!

Is this normal or what's up with the car?

Any advice/help would be great.

Thanks guys.

Ok dude I have exactly the same set up as you minus the cams and cam gear and I make 230 rwkw on my rb20det.

The RB is very reluctant to release torque before 3000rpm. Remember...

1) It's a turbo and turbos are designed to make power when they are on boost - NOT ON VACCUM. My boost starts to come on at about 3300 rpm and this is when the car starts to become torquey and fun.

2) Its a tiny displacement 6cyl turbo with less combustion to push more cylinders than any other nissan inline turbo.

With this said however there are a couple of things you can do to combat the lag (apart from getting a tune which I would recommend first as mine is not very laggy even down low)

1) Regap plugs to 0.8mm

2) Buy a performance flywheel

3) Get a proper, sealed and insulated cold air intake...any exposed pods in the engine bay will be sacrificing horses due to heat.

4) Practice launching the car as you get next to no lag off a good launch and this can be a drag launch or an every day town launch

5) Swap in an rb25det (which i personally could never bring myself to do as the rb20 is the sweetest sounding engine in the world)

i rarely got past 3k.

so ur saying if i keep all gear changes under 3k without kicking the turbo in then from stat to finish ill always be slower/behind other cars?

even lilttle 1.3,1.5L etcc are faster/ahead of me?

dunnoo. if u guys get what i'm talking about but yer... maybe u needa be in the car to understand..

everyone that sits in my car thinks its slow cos i keep it under 3k and not let the turbo kick in... but boy do they get a surprise when i rev it though..

lollll..

i'll get a retune and fix a few little stuff and see how i go..

=)

Lol rb20s are crap down low with the stock turbo, one making 240kw will be absolutely gutless below 3.5k, I wouldn't be surprised if 1.5L non vtec civics and barinas are faster off the line due to the conservative cams and variable valve timing they have.

You NEED to rev it to go anywhere, I'm talking 4.5k for daily driving otherwise why the hell did you buy it? should have just bought a commodore if you want to drive around at 3k lol. The fuel economy should be fine revving it out with daily driving, my 240kw rb25 gets a beating everyday and it manages 14.5L/100km with stop start peak hour driving so I really can't see how you could be worse than that, you would be lucky to get it below 12L/100km anyway.

So drive it like a skyline or sell it, I don't understand why anyone would buy a skyline and drive it under 3k everyday, it is a puny little 2L six, that is equivalent of a 1.3L 4 cylinder if you take 2 cylinders off it lol, TINY engine with cams and a turbo that suit high revs.

Its a short stroke, low compression engine, I have no doubt that a lighter non turbo eccono box is faster in that rev range, its what they are designed to do, where as the RB20 is designed for revs (short stroke) and boost (Low compression)

      The German place in Cabramatta was rock solid, fresh pretzel cooked to order back then. Then it went all quiet, after all the poker machines were removed, then I believe it closed for good. I did drive past the other week and noticed outdoor lighting a big screen, but no idea what is there now.

      Yeah I suspect even if you hold airmass per cycle/cylinder constant if you get too far away from stock you're still going to have problems running the factory tune within the bounds of the factory load scale. Cams, different displacement/rod ratio, etc. I'm just lucky that the GTIII-SS with wastegate boost + CA compliance cats is pretty much equivalent to stock turbos. When I have actual space I can finally get it tuned and modify the fuel system for flex fuel to 100% handle any detonation concerns when cranking the boost to whatever those dinky turbos can put out.

      I would say no, why, because my daughter, who also lives in Goulburn, hasn't recommended us going there Pity, as we miss all the German joints around in Sydney, actually, the restaurants are the only thing I really miss about Sydney, and a special mention to Ishibanboshi at Bondi Junction, their Kara-age Don is heart cloggingly deliciousness (always added a special boiled egg...or 2) 😋

      Does that German restaurant still exist in the old place out the NW end of Goulburn? When I say "out the NW end of"...I am really being vague. It was 1997 when I was last there, and the only point of reference I can recall is that it was on the opposite side of the main drag from the big merino. And when I say "opposite side of the main drag", I don't mean "on the main drag". It was either a couple of streets back from there, or might have even been out in the sticks a bit further. Was an old farm building or mill or somesuch. And when I say "the big merino" I might actually be thinking of a completely different part of town, because I just looked on maps and the big bugger is not where I remembered him to be! The food was good, consisting largely of various German mystery-meat sausage/loaf things and kartofflen.

      So while the second sentence is completely correct and the whole point of the conversation, the first sentence bears consideration. If this bloke is just hoping to throw big turbos on and drive it around, because there are no helpful facilities at all in his tropical paradise** then he likely has zero chance of even knowing what the TP is on the last column in the stock maps, let alone know whether the ECU is operating anywhere near it or past it. So the point is very very moot. And, per what I said before, at stock boost on those turbos, you may well be off the end of the map. **I'm just back from Vanuatu, so I know exactly what small Pacific nations can be like wrt paradise without requisite facilities. But it's not even that simple. I put a high flow on my car and had to drive it around without a proper tune because of the lack of opportunity*** to put the bigger AFM and injectors into it to allow it to be tuned. I had to turn the boost down to less than I had before, and back off the boost controller's ramp, because it was exploring parts of the map that it didn't drive in before, and really couldn't access for tuning on the dyno either, and so was pinging. It was still well within the last column, because when I first**** set up the Nistune on the Neo I rescaled all axes of the maps to give some more space to explore. ***Family dyno was broken ****This was 13 years ago, and the TIM thing wasn't a thing then and so TP would definitely grow when pushing past the stock tune's limits.
