Exhaust tip and neons. fully sick :D

Nahh seriously ure best off starting with an air filter/ cold air intake as its the easiestand cheapest. ure next step is ure exhuast, nothing fancy, just some good headers/extractors, whatever u want to call em and a 2 and 1/4 inch pipe with a high flow cat and muffler. That should be around $1k.

From there its time for suspension work, brake upgrades fuel management. THe list goes on.

Check out my sig, that's what I've done with my car and in that order to give you an understanding of the power gains you'll probably achieve with simple modifications.

I think the general consensus is that a pod filter would give you greater gains than just changing the standard panel filter to a performance filter.

For $25 you can pick up blitz style air filters from A-Spec in Murray St. I've just replaced my first one after about 18 months and they're fine.

Yeh dont go out and blow ure money on some BS HKS super hurricane gizmo. The $25 dollar air fliters with the concave centre are fine for the amount of air you will need.

The standard airbox and the ducting going into it is not so great on the 33, that little bottle neck where they ran a hose (radiator or something) past it screws up the flow big time.

With the new filter u can do 1 of 2 things. Move the filter all together to in the bumper some place where it will get good air flow but hopefully not much rain and stones and stuff. Second option (preferred) is to get creative with an angle grinder and some PVC and make huge duct to the front bumper via the wheel arch. Be careful with this as u dont wanna cut structural steel.

okay,

when mine was stock etc.

i went to many places who all told me the same...

dont BOTHER with getting a pod filter.. the stock setup is more than enough for a non turbo.

get a high flow panel filter (HKS or something if u really want... i did and it worked a treat... felt a bit more responsive...) This is because the stock air intake, has that lil snorkel bit that sucks air from the front of the car.. forces it into the air box. having a Pod would basically kil this idea with a non turbo, i dont think it sucks as well being NA etc.

get a full exhaust.

i had a catback cypher exhaust 2.5inch and stock airfilter and got 15.8 odd at motorplex.

my car is already decked out with suspension when i got it though, so i dont have to mod that :cheers:

but definately do those asap. theyre fun! :)

P.S. I still have the Cypher catback 2.5inch mandrel bent exhaust system sitting around since i upgraded my car. your more than welcome to buy it off of me. PM me if ure keen

A decent CAI should do this and more. The stock airbox blows in my opinion. That little duct that sucks air from the front is tiny.

That should speed you up a tad.

*Honestly id get what has been said above.

Make it breath better and fart better, that'll be the biggest bang for your buck.

Breath better and fart better.. hmm thats a good one..

Best of Luck mate !

enjoy your new car!

It kinda straight forward.

Get as much ducting to the air filter with as little cutting as possible. Make a good weekend of it. Also build a box or heatsheild around the filter to redcue heat sink from the engine.

Oh and if you want to move the filter all together make sure teh AFM (little thing behind filter with wires coming out) is in a nice flat spot where the airflow will be smooth.

when building your new CAI keep this in mind for every bend that the tubing has to get to the T/B subtract 7% of the power... this is how much the bends slow down the volume of air.... a simple way of testing this out is watching the way water moves through reticulation systems (half cut versions) but if you must have it coming from behind the front bar have a section just before the T/B that has a larger diameter than the rest by about 20% this will allow for the loses... hope this makes sense

Also look for a bigger T/B and a port matched intake for better flow

Try chasing up some better cams this will give better top end

and then of course a really good well made mandrel bent 21/4" tuned length extractors

and management to even out the air- fuel ratios

      Turn signal wiring question

      By OakvilleGTR · Posted

      Good morning all, Bit of a random question but figured I’d finally throw it out after wondering for a long while. Before I start, I'm hoping to do this purely out of personal preference. I think it would look better at night, and don't mind at all spending a few hours and dollars to get it done. I've copied this from a non-Skyline specific forum, so I apologize for the explanation of our headlight switch setup that we all know. Here we go: Zero lights (switch off) Parking lights (switch position 1) being a rectangular marker on the outside of the housing, my low beam being the projector in the centre (position 2), and a high beam triggered by my turn signal stalk. Most North American cars I’ve owned of this era have power to the amber corner (turning indicator) light as part of the first switch (parking lights). I’d love to have these amber corners receive power when the headlights and parking lights are on (headlight switch), yet still blink when using the turn signal which is of course a separate switch. Hopefully I’ve explained my question correctly. Is anyone aware of a way in which I might be able to achieve this? Thanks in advance

      Mistakes were made, my R34 Story

      By Kinkstaah · Posted

      My heads are cathedral port! It's likely possible, but I don't want to add any extra moving parts (I know they don't move) between the heads, manifolds, etc. It will also affect how injectors/fuel rails etc sit and I don't really know if it would change how the FAST manifold goes/sits/fits. I have the LS6 steam pipes already as I have a very late LS1 block so it should be fine. I couldn't find anyone who had ever actually used one for this purpose, it seems 100% of people grind the water pump. The thermal spacers are 12mm and are half way to the cost of the newer water pump anyhow... so if it comes to that I suppose I'd rather buy a new pump. The bearing in the pump I do have is a little.. clunky, but it hasn't done that much time and I never noticed it when the car was together in the past few years, so..

      Lower A arm Skyline v35

      By sonicii · Posted

      The bushing has failed, not all that uncommon for a car of this age.  Any mechanic should be able to push in a new bushing for you, or you can probably buy the entire lower control arm, complete with bushes.

      Could you not use "thermal" spacers to give the clearance, like the ones I used between the blower and head? That raised the manifold height by around 10-15mm Albeit the ones I used were for cathedral ports, but I assume they have similar for rectangular ports????

      Looking for autoelectrician in Perth who can do the OEM to double din stereo upgrade.

      By Red Sky II · Posted

      Thanks Paul I reached out to Autotainment but they no longer work on JDM cars as the guy who used to do the work moved on and is no longer doing that kind of work. I am talking with Level Up Audio though.
