Stupid Questions?

[dezz]

Ok guys, so i dont actually own a skyline yet, but i dont think it'll be far off, as i'm currently looking at a few.

I've been reading your forums over the last few days, and seeing what you guys are doing to your beasts etc...

These questions are probably stupid (to those who know the answers) because they are probably the basics.

First of all, what exactly are people referring to when they say, front/dump pipes? can anyone explain, and post some pics of what is being talked about?

what next...

what is needed for a turbo car to have a blow off valve fitted? Does it need to have a FMIC with the piping etc, or can a blow off valve be fitted (and heard) with the intercoolers that come on the R33 GTS-T stock (thats what model im looking at by the way)

i was reading about a bleed valve i think its called...what exactly is that, and what does it do?

also, a stock R33 GTS-T, which has a 3 1/2" from the turbo to the cat, and then 3 1/4" from the cat to the tip...is that a good thing or a bad thing?

it used to have a FMIC, but doesnt anymore, so i guess its using the factory cooler...it will probably have a HKS pod filter with a heatshield fitted as well, but other than that, its stock (manual if that means anything in relation to this)

If i buy it, i'll probably get a FMIC eventually, as they not only look cool, but from what i've read, are a good thing to have performance wise...

also, any other general info about skylines , R33 GTS-T's in particular, and turbo cars in general that anyone feels like offering (in terminology that i can understand, not being very mechanically minded, but not a complete dud when it comes to cars...) would be greatly appreciated.

If i do buy a skyline, then i'll definitely be a part of these forums, as after only a few days i've already found things that i'd be interested in...(for sale items etc)

also, I read on this page http://members.dodo.com.au/paul/docs/top10mods.html

about the "cold air box".

now the pod on this paticular skyline im looking at has a proper heatshield seperating it from the engine, but is a cold air box something different again? I looked in the group buy section but couldnt find 1 for sale, so i'm guessing that page was written a while ago

Thanks

A dump pipe/front pipe leads off the turbo housing and joins up to the cat converter, and can be a single or split pipe set-up...

You dont need a FMIC to fit a BOV, all that is needed to fit is an adaptor from the stock bov to the aftermarket one...

A bleed vavle basiclly allows you to increase the boost above the standard amount by placing basicly causing the wastegate to stay open...

the exhaust you mentioned will be fine as most exhaust systems are 3" in diamiter or thereabouts...

yes a FMIC will be a good mod, allowing you to run a bit more boost, keeps intake temps down, and also reduces the risk of pinging...

a CAI is different from heat sheilding because generaly there is a intake pipe mounted low down in the front bar of the car to route cold air to the pod...

for any other info on skylines i suggest using the search button for more info...

good luck on the car hunt...

let me hve a go at this...

firstly, your questions are NOT stupid. at one stage in all our lives we knew nothing about cars and learnt the bsics first. you will find that if you hang around these forums long enough then you will get to know your car very well and pick up some valuable knowledge...

Q: what are front/dump pipes?

A: well in a turbo car there is an exhaust manifold that sort of bolts onto the side of the engine and all the exhaust gas escapes through that. This manifold has 6 pipes (as its a 6-cylinder) and these meet into one big pipe. The turbo sits on this and when the gas flows throught the turbo it spins the wheels and you get boost. When the gas has spun over the turbo's wheel it is now useless and needs to excape, and so it passesthroug hte rest of the exhaust. A skylien exhaust consists of 4 pieces: front pipe, dump pipe, cat converter, and cat-back. Basically they are just sequential pieces of pipe that lead from the turbo back out to the atmosphere.

So in answer to your question, the front/dump pipe is a pipe that bolts onto the back of the turbo and then passes under the car and bolts onto the cat, and it takes exhaust away from the turbo.

Q: what is needed for a turbo car to have a bov fitted?

A: if you are looking for a skyline, then it already has a bov in its stock form! this is good news for you as they are a great unit and don't need to be repalced

Q: what is a bleed valve, and what does it do?

A: it is a little valve that sits in a tube and removes air from the tube. don't worry about that, just know that it is put into the system that controls how much boost the car makes, and it allows the car to increase its boost level for extra power!

Q: the exhaust is 3.5" from turbo to cat and 3.25" from cat-back.. is that good?

A: yes, that's good (taking from what you now know about the dump/front pipe, the car has a 3.5" dump/front pipe). that exhaust might be a bit loud but will flow nicely and allow the car to make some nice power.

Q: used to have a FMIC

A: that's cool the stock intercooler is not bad at low boost levels and i can't imagine why it wouldn't be up on when the FMIC was removed. keep your eye on the for sale section for some cheap intercoolers and piping kits. they can be had for about $600-700 all up if you doyour research

Q: HKS pod with heatshielt

A: cops hate pod's and give peopel a hard time with them. its good that it has the hetshield, but if it comes with the stock airbox then one ofthe best thigns to do is simply buy a K&N panel filter and place it into the stock airbox

when you buy a car, give it a good service and have it checked y a mechanic. read the forums and get some advice if you are going to upgrade things as meny people have done whateve you are thinking about and can give you some insight into how it turned out...

best of luck and i hope you understood what i wrote!

oh, adn have a read of this:

http://www.skylinesaustralia.com/forums/in...showtopic=35129

thanks for the replies guys...good to see there are a lot of sensible and mature guys with these imports.

i'm a big ford fan and always have been, but i've always liked imports, and this time round i thought i might as well go for 1, while im in a position (finacially) to do so.

WazR32GTSt: thanks mate. very understandable responses.

flipknot: PM me with what your selling and i'll have a look

[fLipKnot]

WazR32GTSt: Very well said indeed...maybe you can enlighten me on how we go about changing the stock turbo in the R33? Besides purchasing the turbo, do we have to purchase anything else to fit the turbo into the engine nicely?

[WazR32GTSt]

sorry mate, my knowledge only extends to what i have actually done myself and i have not had a turbo change ...................... yet (he he)

from what i have read through, as long as its a T3 flanged turbo designed for the skyline then there should be no real engine bay mods to make it fit. the only mods that may be needed are ECU, fuel pump, injectors, depending on how far you want to push the car's state of tune...

hopefully soemone else can give us better details!

best of luck,

Warren.
