Sorry to hijack, just want to know if the plant in the tank is a Water Sprite? Cheers!

:lol: that might not be such a good idea. It will mean that I will have to fake not being able to see the computer screen.. which means then that i can't really work. Unless my dog can work for me? :lol:

I think this is a question that probably plagues alot of dog lovers out there. How does one manage to have dog and yet work full time. I really really like dogs.. esp German Shepherd and have always wanted one. But the idea of leaving him at home while I'm at work just does not cut it. It is as if I have to win lotto and quit my job before I can have one. Anyone out there in the same situation? These dogs are just so damn gorgeous and I don't think they deserve to be kept alone at home for the whole day. Its too bad I can't bring them to work. I work in an IT company and I don think dogs are allowed in the office area.

Righto thanks for that. I'm just trying to look at it at every angle possible before I blow money on wheels. From what I can read on the internet, 1 pound reduced in the rotational weight is roughly 3-4 pounds of the car''s static weight and that every 10lbs reduced in static weight = 1 HP gain... mulitply that by 4 wheels and it would be a significant increase? So if I were to go for the same wheel size but lighter wheels, I'd be reducing 2kgs or 4.5lbs of weight on each wheel. 4.5lbs X 4 wheels X 4 = 72 lbs. This is 7.2 HP gain so I think its worth it? Then again you can't believe everything you read on the internet. :lol: If I went 18's then rotational inertia plays a big part? Its all so confusing to me. :-? Probably the reason why I was interested in the calculations. Thanks again Ira!

Which is easier to spin? A 17 inch diameter wheel weighing 9.6 KG vs a 18 inch diameter wheel weighing 8.7? The reason I ask is because I'm thinking of upgrading my car to light weight racing wheels but not sure if I should bump up to 18 inch but still be lighter then my present wheels. If its gona reduce performance, then I'll go for the 17 inch racing wheels which weight 7.7 kgs. Anyone can shed any light on the calculations involved regarding rotational inertia?

Is turbo charging a Spec S safe? What about Supercharging.. in any case.. doing force induction on an engine that was not made for it to begin with.. isn't that bad? I guess i could run lower boost since the compression on the SR20DE is much higher then the turbo version? Does that mean less turbo lag as well? Maybe I'm being alil unrealistic about the HP gain... will 5-10 hp gain be even noticeable though? Oh, and how much HP gain if i changed the Intake and exhaust flows? lol sorry about all the questions... As far as engine mods go.. I'm still very green!

Lol! I have a learner license on a motorbike. Bought a 150cc bike during Jun and been taking it to work until my old car broke down so thats why i got the Nissan Silvia (been eyeing one for a long time now). Because of the bloody learner restrictions (which i think is bloody rediculous) I can't go out and by a GSXR or a YZF or Ninja etc. Pretty keen on a 750 GSXR 08. I mean, I've plenty of experience on bikes.. just that the process of getting a license here meant i had to go through the same procedure as a 16 year old (is that the age restriction)! Anyway, back to the car... Its a N/A car and I don push the car too hard as to prolong the lifespan (Don see the point pushing the car hard on public roads). Been thinking about suspensions as well but engine is more on getting the acceleration back to how it was.. or maybe slightly better. BTW: I don like drag racing.. more of a circuit guy. No offense to all the Drag racers out there.

Hi Guys, Just want to know if engine modification on a Nissan Silvia Spec S will harm the lifespan of the engine? I was looking into things like the exhaust manifold... Cold Air Intake... things that will not restrict the airflow. Not sure about bolt on headers and what not.. all I want is an extra 20 - 40 gain in HP (anything more will be a bonus) so that my new Wheels done feel so sluggish when compared to the stock wheels. Any input will be much appreciated!

Yep I passed him the keys to the car today. Got him to install a couple of extras in the car like aftermarket gearknobs, handbrakes, pedals etc. I figured if anything were to happen to the car then he'd be responsible. Thanks again guys!

I think I'll tell him that I'm not comfortable with him taking my car. At the end of the day... its my car right? Plus insurance and crap like that.. too much of a worry and I cannot work as well. Thanks guys!

Quote from Nissansilvia.co.nz: It could be the balancing - but I wouldn't discount the hub ring. What he's talking about is hub centric ring. The center of your hub sticks out ~10mm and has a shoulder for the rim to rest on. The rim has a hole here. The size of this is not standardized, so aftermarket rims are generally larger and require an adapter to make it fit snugly over the center of the hub. This is what he is talking about. A rim should center on the hub, then the wheel nuts put on to hold the rim in place. The wheel nuts should not be relied upon to center the wheel. When the wheel is bolted up it is the tension on the studs (and the friction between the back face of the rim and hub) that holds the wheel there, neither the studs or the hub center should be 'taking the weight'. It's not unheard of to have the wheel not center properly without the hub ring - that's why they have the things in the first place. If he's from a professional business and he doesn't look slimy I'd trust him. I'd take the car to them though. At the end of the day he warned you there may be an issue, there is, and he's trying to fix it. Don't think its a spacer so should be alright? Anyway, I think I'll use the insurance company excuse... And probably consult my friend who brought me to the guy in the first place. Really don't like someone else driving my car... especially since I just bought it! Thanks guys for the reply.

Hi Guys, I posted the message below on NissanSilvia.co.nz but wanted to get more opinions and advice from people with more experience on this. Have a read. All comments and advice welcomed! thankS! New to the modifying business. Last Friday, a fren of mine managed to get a pretty good deal on a set of 17inch SpeedyWheels Racespec wheels... looks awesome and so drove in at lunch time and had the wheels fitted. There is this ring that the store owner had to put on the hub before fitting the wheel and he told me that the ring was a loose fit... and there may be a possiblity that the steering wheel will vibrate at high speed.. .he told me that this is nothing to worry about and chance are that it won't happen at all. Unfortunately the steering wheel is vibrating! So called up the guy and he told me that he wants to pick up my car (Nissan S15.. I just got it for 2 weeks now) and refitted the ring and then test drive it so that there is no problems. But the idea of someone that I barely know... (met the dude for only 1 hour on friday) and now he wants to take my car.. and bring it for a test drive! It just doesn't seem right. Anyone have experience here? Is this normal procedure? Am i just suffering from new car syndrome or is my unwillingness to let someone else drive my car valid? What should i do?

Btw guys, [email protected] replied stating that they "believe" that it is 95 and turbo needs 98. Although the important thing to note here is that they believe... :-?

Thanks guys for the very informative debate not only on fuel type and octane rating but different types of cars, engines and their performances... etc. I think from all that has been said.. (on this thread and on the other one at nissansilvia.co.nz) I will definitely not go for 91. I love my car... (although my girlfriend does not approve.. well sometimes ) ... i treat it like my second wife.. and so nothing but the best.. and if 95 or 98 will be better for it then yeah.. thats what I'll go for. Thanks again! :bounce: :bounce: :bounce:

Fair enough. I'll try 98 after the 95 runs out. Its currently at 1/4 so nearly there. I hope I've not done something bad to the engine.

Running lean as in not burning clean? How much does it cost to get a dyno test? Thanks! I've also just posted a thread on the silvianz website. And i emailed [email protected] for a manual! Doubt they can help me though.

Thanks for the reply guys. No clue whether the engine has been remapped or not. I would say no because i doubt that the dealer would spend money on that. Its a non turbo so naturally it will have a lower compression rate I would suspect. So far 95 octane has not caused any knocking in the engine... so I know that its definitely not requiring any higher... Just worried that its too high as it might cause ill effects to other parts of the engine.

Hi Guys, I recently got myself a fresh import from Japan. Its a standard Nissan Silvia S15 Spec S 1999. Everything is factory standard so no funky modifications or anything like that. My question what fuel should I be using. At the moment I'm using 95 V power from Shell but i Understand that High Octane for a car that does not require high octane is not good as well. Anyone have any clue? I'm leaning towards 95 octane but I do not know the compression rate of the car and therefore I do not know. Help!

The fuji red have settled down now and all are eating very well indeed! I guess all they needed was time... Thanks for the advise ppl! I have a last question... I was planning on getting 2-3 juvenile discus... Currently have 6... Now once they outgrow the 80 litre grow out tank I will be putting them in a 200 litre tank... If i were to continue the daily water changes... will 8-9 discus in a 200 litre tank be ok? Tank has a Eheim Canister filter running on it as well. Do not want them to end up being stunted... and if its too many then i will stick to 6.

Cool Thanks! I'll give him alil more time.. Hope he will start eating. Cheers!

Ok i'll increase the amount of water changed... Water temp is very stable as I check the temp of the water before pouring it into the tank... as for PH.. i don check that but I figured that with the amount of water changes that I'm doing it should be good... Reason for using the smaller tank is because, 1) According to the breeder that I bought some of these discus from... it will be easier for me to do daily water changes required while they are still young... to prevent them from being stunted. 2) The larger tank is still cycling.. its been going for about a month and a half... and should be all good in in the next two weeks or so... Also, I have a driftwood in the 80 litre tank with very healthy, growing/propagating java fern. I also have a light unit but i dim it down my covering the top of the tank with a cloth so the light gets diffused. I'm just worried that he is not eating and will weaken and be more susceptible to diseases... How long can they go without food?

Well... all the poo that I've siphoned out are red with alil white... just a lil stringy stuff but majority are in clumps. what does white poo signify?

Hi Guys & Gals, Recently got 6 juvenile discus in a 80 grow out litre tank... They range from about 4-6.5cm in length... (they will be moved to their 200 litre display tank which is currently cycling and that they have outgrown the 80 litre tank... Probably in the next 2 months or more...) 2 Alenquer Reds 2 Red turqs 1 Blue/white cross 1 fuji red. Everyone is eating well except the fuji red!!! He comes out and stuff... but when i get close to feed them.. he goes and hides behind the filter inlet... Are fuji reds extra sensitive?? Or is it because he does not see a fellow fuji red... and therefore feels less secure? I'm pretty sure water quality is very good as I run a canister filter and do daily water changes of 25 - 30%. Been doing this for about 2weeks now so plenty of time for the discus to settle in... I'm currently feeding them Discus Tucker (frozen food from LPS), Frozen Bloodworms, tetra color bits and tropical flakes. Most of the other guys are alright but when one starts to freak out (the fuji red) the rest seem to follow which kinda sucks. Any advice to get the Fuji red to eat as well as make them less skittish would be great! Thanks!

Henry looks happy.. Will cut down on the amount of food that he gets too ease the pressue own his little tummy... Thanks for the help guys! Appreciated it. I'll keep you guys posted on his condition..

Poor henry... I'm not at home til tomorrow evening, so I'll check his poo then... hope he's okay... I read up on some forums that I could dip his food in garlic extract to help treat the infection? If there aren't any medicated foods here, I might just have to for the extract.
