i vote scare tactics, its 12 midnight by the time he goes to work the next day he'll cant be farked transferring it from his phone to the pc. just say you drove your grandmother to maccas.

hahahah @ potato... i wouldn't have thought that it'd work since you are technically going from: 2.5" -> 3.0" -> 2.5" if you turbo'd your NA and didn't declare it, then i suppose you "might" get away with it, but then your "mod" would be considered illegal without a mod plate. and your royally reamed if someone cluey were to check your manifold only to find a small snail hanging off the side of the head and your back at square 1.

in comparison to what? bar the RB30DE hybrids and Autech RB26DEs, the RB25DE is the largest capacity non turbo in the RB series while i don't claim to be an exhaust specialist, i do see some faults in your statement. first of all the correct term for your quoted "backpressure", is infact called volumetric vacuum. what this describes is that the gases expelled from the system "plunge" the entire area of the exhaust system and creates a vacuum. as the gases progresses through the system, this vacuum will encourage and tend to extract the newer gases being expelled. having a too large of an exhaust system will create an empty weak vacuum, this ruins the flow of the expelled gases causing the turbulence you describe. although what you say about the gases being cooled down does hold some merit, how long do you thing the gases remain within the 2-3 meters or so of metal to have any sort of significant effect in regards to the volume it occupies in relation to molecular expansion? i guess you could describe it as a combination of both, but what you say about changing to a 2.5" will barely have any affect is false. in high RPMs this may be the case, but i would pretty confidently bet some money most of the people on these forums drive in a range from 2-5000rpm most of the time. this is true, non turbo systems (unlike turbo) are NOT under pressure, so in theory you would want to remove as much of the restrictions as possible in order to provide an effortless expulsion of gases. many people have played around with exhaust sizing on skylines for over a decade now. 2.5" has been the ageed upon gospel for a street driven non turbo skyline. however that said a 3" system MAY provide higher power figures on the dyno, but as most people should know a rwkw number is most definately not an accurate representation of the car's drivability.

no worries jeremy... since most of us are dealing with a similiar situation, i'll put in my 2 cents. choose your exhaust system carefully, especially on NA cars they will tend to be very very drony. NA_R33 had a set of these extractors and a titanium 2.5" system with a cannon - the headaches you used to get sitting near, around, in the thing was enough to drive you nuts! stick with something simple and pay attention to resonators. let us all know how you go with your new systems

thank me after they arrive at your doorstep fellas, the hardwork is done - it's just the waiting game now. glad you guys are happy so far.

ok guys - payment all recieved. still waiting on a few delivery addresses. I will PM each of you with what I will be emailing to partsco... this is your last chance to confirm or make any changes to delivery address, extra parts and so forth. Cheers Eug

thanks for that jeremy. pm sent, and payment recieved from jeremy

alright guys, i've sent off another email. if you can please ask these questions much earlier - as its difficult to correspond with them in multiple emails. please check their terms and conditions on their site: http://www.partsco.com/partsco-hibernate/legal/terms.jsp i will be collecting payment now, please check your PM inboxes.

josh, u reckon a certain lemon r31 with rb30det making 11ty rwkw could do a sub 1 minute up there? <3 u & dan!!!1111oneoneoneoneeleveneleven

i may be interested if this is a go'er

have your AFRs cleaned up, it won't entirely solve your problem - but it is a little over the shop. do you have an SAFC, ecu, chip or anything? as to your power issue, the graph looks fine to me - but you've had history with the car, so just start troubleshooting. have a fiddle with your pod filter, service the car, look into timing advance/retard, etc. that said - the dyno always feels/drives differently to when your actually on the street, so don't take it as gospel. does it "feel" slower to you?

ok dude.

ahh you sure wasnt your flux capacitator pete?

sorry bud - out of my price range. good luck with your sales.

got a block your selling? price?

yeh its not a fast number karen

no worries jeremy.. 1st post ammended. i'd like everyone to check if everything i have stated in the first post is correct. ultimately we'd like to get everything done, so it can be in oz in time for christmas - otherwise we'd be looking at a january/february 2007 delivery because of christmas - cos of their holiday. just a heads up to those involved.

http://www.skylinesaustralia.com/forums/in...t&p=2659059 another update guys... please check the first post of the group buy thread - make sure everything adds up accordingly and is correct. confirm with me and i'll provide you with bank details. cheers

cool stuff Sean'O ok guys. HPC coating was orignally just on the outside. but i have sweetened it to get done both inside and outside and in silver for the agreed price Sean'O if you are in, that makes 4 and we are good to go in regards to payment: - check first post for your total, make sure everything you ask for is correct and the total adds up accordingly - confirm in pm with me if you wish - i will pm each of you with my bank details to deposit and please include your forum nickname - pm me back the reference number as well as your desired delivery address - i will pay all the fees associated with international transfers (since i was going to buy them anyway) - then i will just make 1 large payment as opposed to doing 4-5 seperate ones. - then we wait.

macca_r33, whitezuluR32, Sean'O ???? lots of yes, but no follow ups... whats the go? nick jeremy and myself are waiting to go ahead with this

that looks very cool. whats the vin? i'll run it now...
