More Power!!!

[myr332]

Man, I am posting like a demon today !!! (all of 2 post .. yes that is big for me..)

The question I have for everyone is a selfish need for more power.... I'm sure you can all sympathise with this..

Let me list what I have currently..

'Line R33 GTS-T '96 Series 2

Air pod

Intercooler

Full 3 inch Exhaust from turbo back

BOV (full-e sik m8)

Power FC ECU

Profec B boot controller

I'm on the market to get a new clutch and flywheel which will of course allow me to get more power at the wheels, but I am just waiting for that group buy thread start up again!!

Now I've spent a fair bit of my saved up pay packet, so now I am after power gains for as cheap as I can...

So without getting extravagant and buying a new turbo, what other modifications can I do to make more power at the wheels that wont break the budget? Is there such a thing as cheap power gains after I have done most of my stage 1 work already?

Be very interested in hearing people's experiences with modifying their cars and the budget they had to play with.

Look forward to reading!

Thanks fella's..

its screaming for a new turbo, it would love a HKS2535 or hi flowed stock or something similar

would be the next logical choice

Next step would be a set of HKS cams if you dont want to change the turbo! Also a bigger AFM might be a good idea as the pressure drop wouldnt be as much. Altho Im not sure how big they are on the RB25, but all I know is that the SR20 (50mm) is barely big enough for a kei class car!!

RB20/25 AFM's are 80 mm.

Treat me like an idiot man ... (well not literally)

So each of the below; what is the benefit of each particular modification, how much on average would it cost to replace, what's installation like? time required, difficulty etc.. (i installed all of my other stuff so i'm not too fussed about getting my hands dirty) and what kind of power increase do you think i would get?

i'm still trying to pick up about modifying cars, so i'd appreciate it if you could play teacher for this one:)

cheers dude..

A cheap but worthwhile improvement is some shrouding around your pod filter, and some ducting behind the front bar to ensure that air is passing thru your IC, not around. Next i would look at some cam gears, then be happy with a very effecient, nicely setup car.

Outside of that if you want more power/driveability id be looking at a new bolt on turbo that will make use of your current exhaust and filter setup, and a new fuel pump.

Thanks man... once again though, good suggestions but can you quantify any of it? like what type of power increase I might get, the cost of purchasing things and how hard to install?

Cam gears, depending on brand will set you back between $400-500, so once fitted and car tuned will likely to end up being just under $1,000. With the Pfc you may only see a 5rwkw gain, but you can get a bit more midrange and driveability from it.

The ducting can all be done yourself for about $40-50, just get some thin aluminium, some foam and go to work.

Power gains wont be huge, but you can be sure that your air filter inlet temps are low as posible with good shielding and ducting for the filter, and then your intercooler is workign to the best of its ability by ensuring that air is passing thru it, not around it. So for next to nothing you are likely to pick up some throttle response

how dificult are cams to install? and when looking at purchasing some i assume your bettergoing to a big name like hks? and wahts the price of some hks cams?

An 8 degree celsius increase in air temp cost 5% in horsepower. So if it's 25 degrees admbient and the under bonnet temp is 60 degrees, then you would loose ...............

I am sure you can work it out for your self.
