Need More Grunt... Whats A Good Mod...

[4drftn]

refer to my sig hehe

was thinkin of gettin one but not now

[mark_sudakov]

top run says 35psi (if thats what it means)... but im not 100% on reading dyno sheets

You've misunderstood the graph. Your boost level for 221kw is 12-14psi. The top curve got nothing to do with the boost level. It is power relative to the rev range. The bottom curve is boost relative to rev range

^ in other words bottom line is boost top line is power

oh really... well that explains it all... here i was thinkin with extra mods my car was actually slower than stock and something was very wrong... help to know how to read it i guess. :laughing-smiley-014:

..... Well, live and learn.

So, back to topic, if you want more power, look for a bigger turbo.

I'd probably recommend that you look at upgrading brakes and suspension first though. If you can't read dyno graphs (Which is not a big deal) I think it's safe to assume that you're after power for bragging rights rather than track day performance.

Upgrading the raw KW is pretty useless if you can't put the power to the ground.

There is a good ongoing suspension group buy from Sydneykid, also there were some slotted rotors there too. Add in some brembos and you're laughing.

Oh, but you must, must MUST not cheap out on tyres. There is nothing wrong with them being the most expensive addition you make to your car.

So, it really depends on WHY you want more power. If it's for performance, look at the above upgrades. If it's for bragging rights at maccas, find a dodgy dyno place that will give you a high reading.

Oh, and "more power" and "budget" are just about mutually exclusive. From this point on, it will be big $ for you, at least, if it's done properly. The up side is though that you'll be able to drive a pretty nice car.

well would like it for track... one day but not at the mo... yes suspension i need to consider to stiffing up my ride as it has a little bit of body roll in corners... also if a bigger turbo is my best move in getting more power will i need to do much more to my motor to with stand a bigger turbo. would a high flow be any better...

Again, it depends what you're after.

You could get a massive turbo, with huge power, but your lag will make it undrivable on the roads. It's only be good as a drag car.

If you're after track day performance, look at upgrading everything.

First though, upgrade what's on the way out.

look at the clutch, consider upgrading that, ditto brakes. This will give you more control of the car.

stiffen the frame. Depending on your driving style, you may want sway/ tower bars. A cheap addition, but a heavy one.

Remove stereo and speakers. They add weight. Pretty much remove anything you can while remaining legal.

I could go on, but it's all going to come down to what you want in a car.

For track days, you'll spend more time braking and accelerating than you will at full boost, making clutch and brakes more important than a bigger turbo.

A highflow is an option worth considering if the turbo is ceramic. Then, it's on to internals. There are so many options that I can't write them all. You can RB26 it, or add in an RB30 bottom end, forged pistons, bore, thick metal head gasket, extruder polish... all of these have various benefits, but from here on, it'll cost a lot to get a little.

You're best option is to get a CAMS license, come out to track days and have a go. See what you're driving style is like and see how others with a similar style upgrade their cars.

Oh, and the raw KW on a dyno is more of a diagnostic tool. Not all dyno's will read the same. It's pretty useful for tuning though.

So, consider the following:

Daily driver

High top speed

Good acceleration

on a budget.

Now pick three of those above options. You'll have to forget about the other one.

oh ok... that makes me think alot different about things... i dunno i dont think i will go to the extreme of ditchin my stereo and interiour gear ect for track seeing that it might never happen but i would definitly pick good daily driver as one of my options. street performance would proably describe what type of performance ect.

seeing it only hits 14 psi you could probly run more boost but take a pic of your engine bay so people can look and check out what u got... probly high flow turbo or 2530 something alone those lines...but mate by the sounds of things you need to get more of a understanding of your car first....and suspension mods would make the car feel totaly different from traction off the line and thru the twistys.

very true as i bought my car already modified... being my first turbo car (was a commodore man thru and thru) im getting there.... i will post a pic of my engine bay soon i might have a pic but i know it definatly not a top view and wouldnt see much
