GT4 Weight Reduction

Post by Tania »

Hi guys.... I've just joined since I bought a Celica GT4 on the weekend so hello to you all.
Arter this purchase the old wallet is somewhat lighter so I'm looking to start with some cheap mods.
Obvoiusly the first thing to do is to get rid of some of the weight out of this whale of a car.... does anyone have any suggestions?
I am thinking remove the aircon..... any suggestions on this/how do i do it? I've bee told its really heavy and I don't need it ayway having windows and all! (plus it will free up space for a front mount later on)
Any other ideas? What has everyone elso found to be effective?
Cheers guys... have a good one! :lol:

1990 NA6 MX-5 - because reasons
2018 Ranger - Because workcar
1997 FD3S RX-7 Type R - all brap, all the time
OMG so shiny!

Air con is good in summer!!


Only worry about it if you are going to compete in events then you could strip the interior, aircon (does save a bit of weight) sound deadening and everything else that isn't essential (who needs a horn anyway??)

But.. everything you remove will be a sacrifice and take away from the cruiser aspect of the car.

Spend $200-$300 get a ball and spring boost controller and a boost gauge, set it for 12lbs and you'll notice a huge difference as the ball and spring boost controller will eliminate wastegate bleed.. quicker spool and more perceived power.

Take it down the strip as is first or get it dynoed to see where you're at and what difference the mods you do do make.

Air-Con is no need... Just wind the windows down :)

Plus air-con uses more petrol...


Off topic: Has anyone figured out the drag you get by having your window fully down???

Myth Busters...

Having your windows down actually creates more drag meaning you use more petrol...

Why sacrifice your air-con to save 1$ worth of petrol a month?

Weight reduction as a reason is feasible but if it's not a race car I can't ever really justify removing your air-con just to save a couple of KG.

What uses more petrol ? A window that is fully wound down or your air-con on full... at 50km and 100km :)

Well at the mo it is my road car but its done less than 100,000kms so i dont mind spending a little money and time making her faster.... aircon is good for some but im always cold anyway! :?
Lots of my friends have skylines etc which (sadly) are a LOT quicker stock standard than my lovely whale.... I just want to keep up with them! I must admit I have a bit of a need for speed and I just want to go faster! :lol:
Now I know everyone suggests pod filter as a mod (which she already has - although it needs replacing) but if this is my road car shouldnt I stick to the standard filter since the pods are actually quite bad for your engine as the shape and fibre allows for more to pass through??? I know you should never clean a pod filter, but rather replace them as cleaning causes a lot of damage to them... is it worth the money buying a new pod or will a standard air filter do?

Nah thats BS...a good K&N filters very effectively, and can be cleaned over and over.
What model GT Four do you have? I'm assuming an ST205?

Please I beg of you go and try it and then post your results.

The difference that an air-con is going to make to your fuel consumption is going to be minimal...

Having a Pod filter will increase peformance and increase air flow which increases fuel usage......................................................

Its a gt4 right.....

Get rid of your air-con, turn up the boost to 10 - 12psi, get some good tyres and brake pads also get a nice setup suspension wise...

Just because their skyline can be faster than you in a straight line means shit.

Go take them for a drive through some windy road and see if they can keep up with you :)

EDIT: Oh any by the way go buy a $80 K&N pod filter not a $30 repco shit one... the difference is quite a lot

Trust me one of my best mates is a filter expert and even though you are supposed to be able to clean them, it actually causes a heck of a lot of damage to the fibres.... and in the long run having ineffective air filtration is going to damage your car. :( What kind of HP increase can be expected from adding a pod? and how much does a really good one cost?

hmmm... around town though!!!

Having air-con going as fast as it can compared to having your window down......................................

Maybe at 100km its different. But my mate who drove to auckalnd and back said he used more petrol going up there with the air-con than he did coming back with the air-con... (i know many factors etc etc)

But its believeable

Hmm, cant see how the cleaning kit you're MEANT to use on the K&N could damage it, but anyway....
A good K&N pod filter is in the vicinity of $100-120. You can get some Japanese branded ones which do a similar job for about twice the price :lol: I believe the A'pexi filters are the best of the Japanese brands.
If its sealed in a good cold air box, then you'll get a reasonable gain...hard to give a figure without knowing which model you've got.

K&N filters are rated right up there with Apexi/HKS/Trust etc.

You aren't going to notice any power increase just with adding a pod filter and half the time replacing the standard filter with a good K&N counterpart instead of going with a pod will be more beneficial.

Ring Repco and ask for a quote on a replacement K&N filter for your car. Will be around 100-120$ new.

And PLEASE don't just go out and wind your boost up and hope for the best like what was said above. Just winding up your boost (contrary to popular believe) is not always the best way to go about things if you consider the potential consequences.

Turning up the boost by 1 - 2 psi isnt going to do much to your engine...

Also make sure if you do fit a pod filter that it isnt sucking in hot air... Get it in an area where a decent air flow will be hitting it... Sometimes this means moving hte battery to the boot

Panel filters are around $140 RRP. I wouldnt use an HKS filter if you paid me to.

Yes a 1990 GT4.... thanks for that.... shall go and get one this week.... how hard is it to take out all the aircon

And yes winding down the window creates about 15% more drag.... and dont even think about sticking your arm out the window.... the drag that will cause is huge!
I think i will remove the air con as I can never have it on for more than a minute at a time because I get so cold.... and it currently isnt running at the mo anyway.... doesnt have enough charge or something and I can be bothered spending money on fixing aircon
