If you do all the carbon fibre bits, why not do carbon fibre panels on the whole car..........

The cops won't know..........really!

u could start looking at stuff like the inlet manafold and TB upgrades...RPW have a range of stages for upgrade.

i have been looking at the manifold upgrade and the twin tb upgrade they have. cost would be around 1000$ though. i think i'll do that after a few months. any other mods u can think of?

shue how much did your exhaust cost? i want to mod my fto up but i got little budget hehe

the extractors were 550$, hi flo cost me 250$ i think and the muffler and the cat back came with the car.

How much are you willing to spend?

Have you gotten a fuel pressure regulator yet?

Also, what about getting a Magna throttle body and take it to a workshop to modify the plenum a bit for more flow?

Are there any gains by doing a fuel pressure regulator??

shue · Post by **shue** » Fri Jul 14, 2006 4:58 pm

im pretty sure there isnt any gain with the fpr other than it doesnt let the car lean out too much with the mods. the last time lee took a look at it he said with the current mods on my car i wouldnt need a fpr. but yea if your looking at getting work done on the tb/ manifold u'll need the fpr

I don't think there is an actual power increase but rather smoother better response, no flat spots etc

any other ideas guys? other than the tb manifold and fpr ???

But you have to address the intake, and exhaust before moving to other points
Otherwise it'll be like a bottleneck effect

Maybe a shot of NOS?

hey shue, any idea how much hp you would get with that setup?

also, some more ideas
kinda crazy ones though....

1. dual stage exhaust system (butterfly-valve in the exhaust opens at a certain RPM to direct air out of the exhaust before the muffler to allow more air flow for top-end power)

2. re-direct an air conditioning duct to connect up to your intake pipes to provide extra cool air. not sure how that would work though.. and what the ecu would think of it.

The loss you'd experience having the aircon on in the first place would well & truly out weigh any gains there....

to be honest the bang for buck value of this mod is highly debatable. rpw hasnt got a proper dyno figure to give and from what ive heard its roughly about 5- 10 kw which kinda roughly equates to 100-200$ per kw.

Get your intake manifold assembly down to a machine shop & get it ported, get the TB bored as well. Then get it all tuned up.

ive been thinking about it. wont i need to change the butterfly and stuff in the tb though?

Yeah but they'll do that for you, its just an off the shelf peice of brass

sweet. would anyone know who can do this for me in melb? and how much would it cost me for a whole job?

Lots of stickers - every sticker = 10kw Chrome ones are worth 15

but seriously I think a kidney may have to go . . . .

I guess im at a smilar stage to you (well performance wise anyway) and im relising more and more - power dont come cheap in a 2L NA. I guess you either have to be prepared to spend plenty more $$ or be happy with the perfomance you got.

Im looking at stuff like lighter flywheel and better clutch, suspension setup (Tein adjustables waiting), Lighter rims and semislicks for the dragstrip (did a 14.7@92Mph on my 18s the other day) And then investigating stuff like the heads, cams, tb, custom plenium blah blah further down the track - trying to find more info so I can learn off other peoples mistakes etc but info very hard to come by. I work on the princaple everything helps

Hey - for what my FTO owes me I could have had a nice Evo 4 over here in NZ

But for me I like the challange and being different - I bought it to be a show car because they're not so popular over here yet there is still the availability of aftermarket parts

Sorry about the novel
