check your throttle butterfly maybe?

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

hey there... on this forum we have a separate section for V-series skylines. v-series section: http://www.skylinesaustralia.com/forums/Se...lines-f170.html it also seems like the consumption issue has been discussed by a few of the guys before, here's a little head start to get you going. oil consumption issue: http://www.skylinesaustralia.com/forums/Ex...html&hl=oil cheers

yeah the current state of the dollar makes it a bad time to be buying right now. however to the OP, i suggest rather than asking someone to start one maybe you could do a bit of the background work and put forward a deal to the rest of the guys.

most important question. how much are you willing to spend?

pm sent show me pics

not sure why this is in the NA section, but if you search under the cosmetic or DIY (?) section there is a tutorial on how to do it. try keeping an eye out in the for sale section, i have only seen 1 come up for sale, ever. some LEDs a bit of patience and know how and you could make one yourself.

yup start with the basics. unfortunately it's all trial and error. afm, fuses, coil packs, sparkies, etc. just gotta keep testing each one until you find the culprit

oh the lameness Nath. lol @ Reggie

wasn't the legality of modifications clarified to you earlier in the week? who replaced the catback for you? did you ask them? this is your final warning, to cease spamming the forum with new threads all relating to the issue. i will leave this thread open so you may post any future questions that you may have regarding exhausts provided that you search using the above mentioned methods to find your answer first. give a man a fish and you feed him for a day, teach a man to fish and you feed him for life.

mate, this is a no brainer. what kind of response are you expecting from people? if you cant justify $10K for an NA car, then you probably shouldn't do the conversion. i would guess that you would end up spending a lot more doing so. i'm not taking a stab at you here, but it just seems like that you are merely seeking our approval to go ahead with it. go do a bit of homework, price up the cost of a GTST, then how much an RB25DE would be, then go find out how much you can sell the RB25DET. get a quote on an NA differential and all the associated labour costs. don't forget the ECU, engineering, mod plate, extractors, exhaust, air conditioning re-gas, etc. if you plus and minus all those figures and your end total is under $10K then you have your answer! we'll let this thread run for a little longer

however if you are concerned with the legalities of modifications - isn't the most logical place your local transport authority? it varies from state to state, so there's no real point asking here; what might be ok for one of the guys here may not be ok for you. so whatever you read on the forums i suggest that you do a bit of your own homework and pick up the phone to whichever legal transport authority it is in your state. N-dawg put up some good threads, have a look around the forum and see what else you may have missed. If you want an exhaust, here's some threads to get you started. Please ask any further questions in those threads. http://www.skylinesaustralia.com/forums/Po...sp-t194033.html http://www.skylinesaustralia.com/forums/Im...&hl=exhaust http://www.skylinesaustralia.com/forums/R3...&hl=exhaust http://www.skylinesaustralia.com/forums/Ex...&hl=exhaust http://www.skylinesaustralia.com/forums/Pl...&hl=exhaust http://www.skylinesaustralia.com/forums/Si...&hl=exhaust http://www.skylinesaustralia.com/forums/Ex...&hl=exhaust http://www.skylinesaustralia.com/forums/R3...&hl=exhaust http://www.skylinesaustralia.com/forums/R3...&hl=exhaust http://www.skylinesaustralia.com/forums/Ex...&hl=exhaust http://www.skylinesaustralia.com/forums/Ex...&hl=exhaust http://www.skylinesaustralia.com/forums/R3...;hl=r34+exhaust http://www.skylinesaustralia.com/forums/Ex...;hl=r34+exhaust http://www.skylinesaustralia.com/forums/so...;hl=r34+exhaust Cheers Eug

your pics always crack me up! i feel we have been patient enough. eug

i fail to see how he was? correct. everyone can learn from this. this has gone long enough. cheers eug

mate, most of us have been pretty patient with your questions and quite happy to answer them. we have politely suggested that you tried to do a little more research on your own before starting a new thread for each question you may have - as it just looks like you are merely being lazy. treat this forum a little like google and you will soon realise the vast amount of knowledge hidden away. could you please NOT post a new thread for each and every single thought/question, the other thread would have been perfectly fine if you honestly didn't find anything. this is a polite verbal warning. any questions feel free regarding this issue, feel free to PM me. cheers eug

the reason a lot of people ask the same question is because they don't really understand the physics behind exhaust systems. bigger is better if you are in the high rpm applications (i.e. dyno) as the engine is expelling a lot of exhaust gases, the volumetric efficiency is high which improves the flow properties of your system. however at low rpm applications (i.e. street driving) the engine isn't expelling nearly as much exhaust gases, the volumetric efficiency in a large exhaust is low and thus the car will feel 'gutless'. the issue i see with that is, a lot of people use the dyno as a power indicator. the reading is the highest output power at a reasonably high rpm. so of course a large exhaust is going to be seen as an improvement. too small of an exhaust and it creates a restriction. your engine is expelling more exhaust gas faster than you can get rid of; this creates backpressure, where the exhaust gases go back towards the engine rather than out. the perfect exhaust is a variable one, which adjusts according to the amount of gases being expelled. this would be used to create the most optimum scavenging effect which is not easy and most probably expensive. a lot of RB25DE owners have tried 3" exhausts and most have found them to be unsuited for their regular street driven cars. However Cara has reported an improvement with a 3" system, this may be in part due to her motorsport commitments, ecu and nitrous. Not something everyone has. I personally use a 2.5" exhaust and do a fair amount of motorsport activities which involve full use of the entire rpm range. I would not go any larger unless I started making significantly more power as I would be sacrificing driveability. here's a simplification. air/fuel in ----> engine ----> exhaust out if you are putting more air/fuel in, then you will need to take more exhaust gases out. it's a balance and you would really need to do both ends to maximise the benefits. in saying that stock exhausts are a little restrictive from factory due to emission laws. so going a little bigger will improve the efficiency, but going too big then you start to lose that efficiency again. that's the final say. from now on i will close all 3" exhaust threads without any notification.

adam, what mitch said about calculating the area of the exhaust (i.e. cross section) is 100% correct. some of you guys are going around in circles. firstly you need to understand what the muffler is for. the muffler is basically a point where the flow of exhaust gases are muffled by distrupting the airflow. the gases are passed through a series of perforated pipes in various baffled chambers. they are then expelled outside and voila! quiet exhaust. i suggest some of you go and open a muffler up if you get the chance and understand how the internals work. i would say 99% correct ashley! good work. the other 1% i will explain a little later. the other 1%. even if the end pipe of the muffler (i.e. tip) is the biggest, which will help to some degree. it also comes down to the design and sizing of the internal pipes, perforations and camber sizes. so the million dollar comment is: you can not just look at the tips alone. it ultimately comes down to the research and development behind the product it's internals and how well the muffler as one entire package is able to maintain good flow properties and keep the exhaust volume under legal limits. and yes ash, straight pipes would be the sweet sweet ultimate. edit: see pics for a better understanding

hey there, all the info can be found here. no need to start a thread for what's been already covered

nice to see a car being used properly Shane!

oh my... in before the lock!

timo yielded his position bit too easily imo. however the last two laps, awesome nail biting stuff!

what the hell glock again?! i agree, vettel is going to be one to watch out in '09

bloody glock... massa can only wait

man... poor DC!

my last comment wasn't a stab attempt, i was merely stating that it may quite possibly be a combination of other unknown factors including the change of sensors which fixed your issue. however i can only speculate at best. this is just going back and forth and i no longer see any reason for this thread to remain active. everyone was reminded to play nicely and to keep things civil. /locked
