    Rb20det Lag Monster?

    in Forced Induction Performance

    Posted

    LOL...wont overtake them, but being 200-250kgs lighter helps you keep in touch. Imagine if a GTSt had 300rwkws? This guy was a bit shocked when i overtook him and pulled away down the front straight at Sandown (he was even running slicks) smile.gif

    Damn, you've sure got an impressive list of kills :) But I daresay a lot comes down to the abilitiy of the driver. Once the car is up to par anyway.

    Hopefully the person im thinking of reads this and may be able to help you out. A forum goer with a damn tasty GTSt is just about finihsed bolting up the same setup as mine. Im coming up to NSW in Nov to do a few track days so shoudl rock up then for a joy ride or 17 smile.gif
    hopefully my car will be back on the road in around 4 weeks... im in nsw as well so you can come for a ride and see for yourself what its like

    I can't get over the generosity of people on this site. I'll definately have to take you up on those offers. Cheers guys.

    Wow, roy, thankyou very much for such a comprehensive answer. And for actually stating figures rather than just spewing propaganda.

    Firstly, what state are you in. My car will be back on the road in about 2 weeks, and best thing is to take it for a drive and see what you think. Its a long way from the optimum/best set up...but its fun smile.gif

    I wish i could take you up on that offer, but im in nsw, thanks anyway, I def need a ride in a 200+kw rb20 to give me a better idea.

    So they are strong, next thing is they are cheap. For a short motor you are looking between $400-600. So if a pressure line drops of the fuel rail, or bad luck strikes then you are not in a big $$$ hole

    Yes this is certainly a big attraction for me.

    But here is the thing, take the car to the track and see how it compares to the bigger engined cars. Where they wheelspin out of corners with insatant hits of torque to the tyres...i can just flatten the thing and by the time its hits full boost im normally about that point of corner exit that it wont fry tyres.

    Good point, as long as the power arrives in time for the exit.

    The car can still go another 2-3 seconds quicker with more laps and gettign to know the track. So in my eyes thats pretty quick. If 330-350rwkws GTRs with a fair amount of engine, brake and suspension work are doing 1:20-1:21s, then im happy for a completely internally std RB20 with a Trust kit do be 1-2 seconds slower. smile.gif

    Well theres an eye opener, just the sort of figures i was looking for, very impressed to say the least, imagine the look on the gtr drivers face when he gets passed by an rb20 powered gts-t that probably half the money spent on it and a quarter of the upkeep :laughing-smiley-014:

    But on the track, what the slowest corner? 55-60km/h? Thats boost in 2nd gear so not a real issue.

    For a 3,750rpm power band i average something like 215-220 rwkws so its a good wide power band. 2nd gear i rev to 8,200-8,300 rpm, but with the higher upshifts dont have to rev it so hard as the revs drop less from 3rd to 4th and 4th to 5th.

    Thankyou, those figures pretty much alleviated all of my doubts. Consider this thread whizzed!

    but point is, the RB20 wont stop the car from being quick. Hell, LOL after a track day i jumped on the the forum and a guy was carrying on about "that silver GTR was damn quick and sounded tuff" LOL it wasnt a GTR smile.gif

    LOL, excellent!

    Again thankyou for taking the time to answer my questions, I really appreciate and it's people like you make the skyline community so inviting. :):)

    Well, my mind is at ease, still more research to do but the gts-t is looking promising at the moment.

    Goodnight.

    The rb30 works out too expensive if you want it too rev + your likely to overshoot your 250rwkw by a fair margin.

    Well 450rwkw would be ideal, but its the expense thats holding me back at the moment, otherwise i'd go the rb31dett route without question hahaha. :)

    But as long as i can turn the gts-t into a fun track car I'll be quite satisfied...

    ...For now.

    :)

    Get out of my thread biatch!

    LOL, nah just kidding.

    Yeah I saw those graphs in the stickies and some seem to go almost straight up!

    I'll keep on researching I guess..

    I've noticed that rb20's are cheap as so i guess if i change my mind i wont be losing out too badly. But i would like to make sure they can offer what im looking for first. My main concern is slow corner exits. Does anyone here race a rb20, how do you find its response out of corners, what setup and power are you running?

    Cheers guys

    Okay people, first of all, I'm new here so hi hows it going etc.. Now down to buisiness. I've heard a lot of bad things about the RB20DET such as "high performance examples suffer from extreme lag" or "totally gutless down low" etc.

    Now I've owned a R31 for a year, (well used to, its a long story), with the RB30E, with a cam, chip, exhaust. extractors, pod etc, probably pushing around 100rwkw. Now that car is gone and im looking at upgrading while I have the chance. Im very interested in buying a R32 gts-t coupe. But the problem is, the car will see occasional track duties and will be considerably track orientated, (as much as possible while staying street legal), aiming for about 250rwkw. And from what I've heard at his power level, the rb20 will be fairly laggy. Basically i need power on tap at every point around a track, particulary coming out of corners at maybe 3500-4000rpm or so, will there be sufficient power at this point in the rev range with 250rwkw to remain responsive and competitive. If so I will buy the gts-t no problems as i love every other aspect of the car.

    Also, what rpm can a stock rb20det safely rev to.

    Or should I just pay the extra cash for a rb30DETT, basically looking for neck snapping response form a decent way down, say 3500 to redline, the response/torque comes before peak power, but still has to have decent power to be competitive.

    Cheers
