    Need Your Help! - Cam's

    in Naturally Aspirated Performance

    Posted

    I'm running ITB's on an RB20DE in my rallycar. Still a 2ltr for class requirements.

    I don't have the exact spec of the cam's on hand, but they are 280° duration and max lift we could run with the standard lifters/followers. The head has also had a lot of porting done, although I feel we may have gone a little too far on the port size and cams. It pulls strong for a 2ltr, but is very fussy on intake length adjustment and doesn't have the torque I'm looking for yet.

    Cams are a custom grind made by Kelford Cams, as no one really has any spec's on ITB N/A RB motors. I would say the 2.5ltr will be easier to strike the right tune with the cams thanks to the extra capacity. To me it sounds like you are after peak hp and rpm? I'm after the opposite, however the 'lil bugger does like to rev to 8,500rpm all day long on the stock bottom end. Oh and the sound!! :)

    Vids' FYI

    -motor is too flat below 4,000rpm

    Sweet mate!

    I'm a torque hunter like yourself bud :)

    I wouldn't mind upping the hp abit tho, 300bhp would be nice.

    The car's going in again in 2 weeks for a shift light function wiring in that can be used with the K3.

    It should hopefully see some more hp, the garage has said possibly between 30 - 45bhp depending on how much they can fine tune it which they are fairly confident in.

    Here's a vid of how she sound's!

    Hi all,

    I'm over in the Uk, haven't been on the site for a little while but i'm hoping that some of you guys can help me out as you have alot more knowledge with N/A Skyline's than us lot!

    I've got a '96 R33 GTS with the RB25DE.

    I've just completed having individual throttle bodies fitted and mapped up etc.

    Current tuning mods are:

    Emerald K3 ECU

    Custom made throttle body set up using GTR throttle bodies, Jenvey trumpets and Piper X filter socks

    Uprated coilpacks

    Wasted spark set up

    Coby D12 exhaust manifold

    Custom Powerflow 2.5in exhaust system

    Tomei adjustable cam gears (only the exhaust one fitted atm where NVCS has been removed)

    A/C removed

    The car's acheieved 201bhp at the flywheel and now rev's up over 7500RPM.

    Power delivery, torque and fueling have all smoothed out.

    We're now looking to extract some more power.

    There's a shift function on the ECU which means the other adjustable cam can be fitted and should she another 30-40bhp.

    We're looking at doing something with the cam's next.

    Does anyone do aftermarket cam's for the N/A?

    If not, can the standard cam's be reprofiled to be more efficent?

    If so, what's the best profile?

    Any other info on cams or anything else i can do to futher extract more power will be greatly appreciated.

    Here's a pic (sorry pic quality ain't great) of the set up so far!

    Question For Those With Pod Filters.

    in Naturally Aspirated Performance

    Posted

    When I first fitted the pod filter, I didn't do any thing, and there was no gains if anything the car seemed less responsive, specially on hot days and driving around the city, after the inital disaponitment I made a rather crude air box (not pretty but it works) to keep the hot air out, this made a noticeable difference and the car seemed much more responsive, My next step was a cold air feed directly under the pod, I didn't really notice any gains from doing this. If you would like to see a pic of my set up let me know and I'll post one up.

    Hope that helps.

    Lets see a pic plz :yucky:

    4 Stud Or 5 Stud

    in Naturally Aspirated Performance

    Tim, the 200SX is called the S15 in Australia. (just to clear up any confusion).

    Ross, all the hub conversion details have been outlined before. I believe someone even posted up a DIY outlining their progress. Have a look around the forum for details.

    There are plenty of 4 stud rims around, you just need to know where to look. Yahoo Auctions is a good place to start, with heaps of WORK, NISMO, RAY, BBS rims floating around.

    cant believe i'm saying this, but check out nissan silvia forums. they have heaps of traders who specialise in bringing in 4 stud rims with decent widths and diameters

    Ahh, i didn't know that.

    Over here we have the 200SX S13 and S14 and the S15 Sylvia

    Resanator Box On The Oem Air Intake

    in Naturally Aspirated Performance

    Posted

    Does anyone know much about the resanator boxes on the standard air intake?

    A guy over here custom made an alloy air intake losing this box.

    He noticed that this caused his car to run funny and lost power.

    He cut the standard resanator box open and says it has lots of circular chambers in.

    Anyone know how they work and if there are any form of aftermarket one's you can fit?

    4 Stud Or 5 Stud

    ok, so i have been looking for a set of rims. thinking black with a silver rim in 18s or higher. not having too much luck in finding 18s in 4 stud though so im thinking maybe i should do the conversion. what parts would i need for it and price wise what am i looking at (i will be doing the work myself)

    cheers panda.

    You could fit some from a 200sx S13, the pcd and everything is the same as i use s13 steelies for drifting.

    If your struggling, try www.rarerims.co.uk

    They have loads of 4 stud wheels and you can upload a pic of your car and add pics of the wheels on to see what they look like in their virtual garage.

    If you want to do the 5 stud conversion you'll need the hubs, calipers and disc n pads off a GTST.

    Not sure on price wise as i'm in UK so prices differ from you guys.

    Rb25de Tuining Help

    in Naturally Aspirated Performance

    Posted · Edited by ToolmanUK

    Hi all,

    I have a R33 RB25DE GTS and will soon have some Tomei adjustable cam gears arriving.

    The thing is i've still got the standard camshafts in as i can't afford to do anything with them as of yet.

    Does anyone know what the best setting for them would be?

    I've read threw on some of the threads on here about camshafts and have seen about adjusting them to compensate went using turbo cams but can't find anything with having the standard cams in.

    There's another guy back here in the UK with an exhaust cam to fit but we're both unsure with if there's a best setting to get the most out of them?

    Any feedback will be greatly appreciated as there's only a couple of us over here on www.skylineowners.com who have N/A's so info on them ain't great.

    Cheers in advance to anyone who can help!

    What Size Rear Can?

    in Naturally Aspirated Performance

    Posted

    Ok so from reading other threads, this topic seems to have been covered quite a few times but i would really appreciate any feedback.

    Just want to know what size rear exhaust people have gone with and if they found that this element can also effect power.

    E.g. if i have a de-cat pipe with a full 2.5 in system and then have a the rear box also with a 2.5 in tip, is that going to be better than having a 5 in tip?
