donkey

woops, ignore my previous comment, mine dosent backfire up high in rev range, its down low, on deacleration etc sorry

hey there, my gtr does the same thing, i had a wrx with a link computer, gtr with a power fc, now running a G4 link, when summer comes it starts to run rich, backfires, popping, maybe just check your pugs and see if they are fouled?

hmmm yes nismoid, just going on what a few tuners said that its not so much the power (though im sure 380AWKW would kill an engine pretty quick!!!!!!) that will kill the engine, but high revs, and or a poor tune. im just not realing feeling the 320AWKW, so was thinking to move up to 20lbs, safe tune, bring the rev limit from 7500rpm, to 7000? was thinking the extra 2lb might be what im after? robbie ps. running a G4 LINK, no AFM's

just been reading a bit about the -5's. ive got the -5's + usual supports on my RB26, standard internals, running profect b low boost 15lbs high at 18lbs 320AWKW, reading what nismoid said that the-5's really start going around 20lbs, i was thinking about uping the boost to 20lbs, as i feel the -5's are not even trying yet. can anyone tell me is there a much difference between 18-20lbs? or should i head towards 21-22lbs to quench my boost thirst? cheers

hey dirt garage, do you need to re. dyno the car if you install the balance pipe, is there a balance pipe you can buy, or are they custom made? i have -5's, custom piping, etc cheers

hey got an hks twin, real nice to drive, my lightweight flywheel is mean, rapid take off, has a bit of a shudder though, revs drop back pretty fast when changing gears, so when doing quick gear changes pays to blip the gas peddle to prevent the shock on box, diff etc....

what about an RB30?, check out the 'RIPS' website in NZ robbie

hey thanks for that robbie

oh cheers nismoid, i guess that answered my question, ha cheers robbie

just trying to figure out (i have no idea if im right) but say you made 7000rpm the limit, would not all the cars of that model have the exact same top speed because of the final drive/diff ratio? if in theory you could reach it power wise????????

hey does anyone know what the topspeed of a r33 gtr is? what does the car gear ratios alow the top speed to get to, if in theory you had the power to get there? hope this this makes sense cheers

hey there, r33 gtr v spec, 170kms, standard shocks, springs, etc. just wanted to replace shocks but dont need anything crazy, just a good alround set any ideas? cheers

hey i just made 320AWKW on 18lbs, full boost at 3800 (of the top of my head) -5's, custom dumps, inlet, pump, injectors, G4 LINK, std cams, std engine etc, HKS twin light weight fly wheel, asked tuner to do a safe tune, lots of torque 850ft lbs...... got quite bad shuffle though...... robbie

hey there, i have just got a HKS twinplate, in my GTR, real sweet to use, my girlfriend didnt even stall it..........

have you tryed the plug clean yet? just about to do mine

haha, yes only one mule

again im sorry have no idea where they are set? can ask my mechanic

i think i will just stick with the standard cams, really dont want to through away thousands of dollars for not much gain, im looking for torque not massive KW's

hmmm, was going to get the boost turned up to 20lbs and see how that feels (on standard internal motor, rev limit 7500, have a profect b so will also run 15lbs) am a lil bored on 320 AWKW, dont know how much power 20lbs will produce, but im sure more then enough for me, then when motor gets tired go forged rebuild but maybe just leave the cams? ps. sorry dont know what cams are dialled too

hey thanks for advice, yeah cam gears was one of the first mods i got

yeah have read on this forum about not needing to touch them to around that power, but some others say they are a great updrade for low down power?

hello there, rb26 garrett -5's, with all the other bits and pieces would anyone like to help me out with advice on when it is a good time to change the ol' cams, i have about 320AWKW at 18lbs, going to wind boost to about 20lbs for a bit, and was thinking the next step would be cams? if so what is the pick of the bunch for low down power/torque? i see poncams seem to be one of the fav choices, what roughly AWKW does it make sense to upgade? thanks for any help

hey all, so im not sure what my R33 GTR top speed is with its factory diff ratio's etc, but im curious to ask how many people drive there GTR's around at 250kph+ on the street, im sure the ratios are set for around 280-300kph (correct me if im wrong) what im trying to get at is i would like to sacrifice some of my top speed, for some more take off, i mean you spend 10's of thousands of dollars on engine mods when dropping the diff ratio's would be a cheap mod? if so what ratio should i drop down to cheers

check your plugs for fouling, my gtr runs pretty rich, and starts backfiring after about 2 months, especially in summer, the plugs will soot up, i just clean them and problem gone........ hope this works for ya

hey there R33 GTR ive just had a HKS twinplate installed, real easy to drive, has a little shudder from lightweight flywheel, but all good, traffic stop-starts a breeze, big hill starts all good too, not really heavy either. a wee bit of a rattle from plates, but who cares? my girlfriend jumped in and drove it sweet too.... great clutch if you want to to some hi rev launches cheers
