im curious as to how ethanol, a polar molecule is dissolved in a non-polar substance like pump fuel, which is a hydrocarbon ?

no need for funny faces, maybe next time you shouldnt assume, just because i didnt specify which fuel it was doesnt mean it wasnt optimax extreme. to make you happy i'll just add that it was infact optimax extreme 100ron fuel. and im not saying everyone will have problems, im saying its not full proof - and leaking fuel is not a minor concern

someone from the silvia forums used ethanol based petrol in his old CA silvia, and it caused his rubber fuel lines to expand and eventually caused leaking fuel in certain places. he went back to non ethanol based petrol and its fine again now. so while it may be ok in newer cars, i dont think you should be giving a blank cheque to everyone saying its all good, i would say you should be cautious with it, especially in older cars. the warning given by manufacturers that older cars shouldnt run it, is probably also something to consider

whats the deal with the shortage anyways ?! i remember reading something about the worlds supply being used up on the new massive air buses theyre making

haha oops forgot about the different flange... yeah i was referrering to the sr20 version of the GTRS, although i thought it was the same one for the rb20, and only the rb25 one was different with a .84 exhaust housing ?!

i would recommend the Garrett GT2871 - 52 trim. The HKS GTRS equivalent, which has the ability to put down 250rwkw on an sr20det, and still has very good response. although a different motor, it should work even better on your motor since you have the extra 400cc capacity. its the next step up from the gt2530 in the silvia world, the gt2530 will only give you 230rwkw - but has awesome response, extremely streetable and a very nice mid range, i know because im running one on my sr20 although it should be noted that, the .64 turbine housing (GT2871 - 52 trim), starts getting choked in the top end on SR's, it may be even more evident on your motor. but for 250rwkw, its the smallest option, which should give you the best response..

careful with paint strippers, as the one i used expanded rubber

ive been through the same dilemma regarding which flows more, the 040 or the 984. from resellers they say the 040 flows more.. differnet sources say different things. does anyone know why bosch rates the 040 at 6.5 bar where as the others are rated at only 5bar ?? ive seen figures floating around of 240L/hr @ 5bar but the accuracy of that figure is pretty sketchy it has nothing to back it up the 040 also seems to eat up more current then the 984 as well i ended up with the 040, to replace my genuine walbro which couldnt hold pressure on my sr20det..

very nice, your the only producer of auto parts in australia that i know of that have pure carbon products

the silvia community has had issues with these D2 coilovers. search www.nissansilvia.com or www.silviansw.com for the threads. its one of those things where imo you get what you pay for.

whatever happened to this ?

are your products carbon overlays or pure carbon ?

same size ey, interesting cheers for the info

so what do you recommend for a 180sx with stock guards, in terms of wheel width and tyre sizes ?

is this the SK package ?

i second this guy. perfect run have prices as good if not better then nengun and greenline. there service is better then both, i have dealt with all 3... and the best part of it is..... THEY HAVE A SHOP IN SYDNEY ! so give them a visit and pay in person if you wish wrong, see what i said above ! go see them in person if your real worried..

stuck answering to accountants

heres a dyno sheet of the 52 trim version on an SR, just for comparison, stolen from silviansw.com, its TMB's chart.. the overly large compressor on the small turbine, doesnt allow boost to be held up top as the turbine starts choking, but even so its pretty impressive, with whats reported to be an awesome midrange

i doubt it, antilag works by adding extra fuel in to burn in the manifold and thus give extra exhaust gasses. changing timing enough will just cause a late burning of the mixture but its still the same amount of air/fuel, so still pumping out the same amount of exhaust gasses, just burning later maybe the higher EGT's will help though

i doubt cams will give you more bottom end, but will help mid range and top end your at a stage where if you want more response you may want to look at a lightened flywheel or something along those lines, your turbo is damn small already !

your probably right, i cant quite remember, ill check the video. 3037's will only flow 300rwkw each (only haha..) too so either the turbos are wrong or im quoting the wrong amount of power. something i found for you, ~1000hp GTR, although it doesnt give much info on the turbo used: http://autospeed.drive.com.au/cms/A_1560/article.html what i found interesting was they claim to be running 12.9:1 AFR's under load. and again according to the article/nizpro this engine would cost 40K to build. and also this one, not a GTR but pulling 1000hp: http://autospeed.drive.com.au/cms/A_2311/article.html again the turbo choice is kept a secret, but both these 1000hp setups are running singles.

Veilside have a green r32 thats running twin 3037's, making around 1000hp (i think), 0-300kb/hr in 13sec. i have a video of it, i think most people have seen it. i believe its still stock displacement too, but dont quote me.. what happened to that crazy 200sx you had ?

wow thats a big difference in economy when not running an o2 sensor ! makes sense though i guess, since its allowing you to run leaner then stoich mixtures for cruising great thread by the way, ive been reading it all very keenly, alot of good info keep it up

yes please !

i dont see anything wrong with a little discussion, if you feel your not up to it, then dont post. im sorry which part of it am i incorrect about because you didnt specify, your link states nothing different from what i said. your taking my use of the word stationary in the wrong way. what my point is/was, that the vibration of molecules is far different from its movement through space (in gas form), and there not interelated, where as you implied they were. OK so your NOT talking about viscosity when your talking about pouring honey, when its hot or cold, then please explain what your point was. and yes density does apply with gasses, but in liquids density and viscosity are related. its obvious that honey flows more freely when hot, this is because of its lower viscosity, which is also because it isnt as dense. the same does not apply with gasses because the molecules are no longer bonded together at all, where as in a liquid they are, and thats where viscosity comes in. "Like I said I'm not going to add any more to our little debate, it's not really helping anyone else in this thread." i disagree, if i were correct then wrapping your front pipe or cat converter would seem pretty pointless and a waste of money. if you are correct, then yes there is a performance gain to be had and its worthwhile doing. i think its worthwhile to find out which is the case, so people can make informed decisions were having a discussion about it, putting our ideas forward and debating the issue - but it seems you would rather belittle me with your greatness and dismiss further discussion, which is what a FORUM is really about, isnt it. if im incorrect and im happy to be corrected, then please argue your case with self explanation instead of just posting links.
