with the p20 will it be more resposive down low and alow more top end or what am i loosing without the p18

[QUOTE=blue.spec;387016]with the p20 will it be more resposive down low and alow more top end or what am i loosing without the p18[/QUOTE]


no p20 is a bit more laggier.. coz its a bigger housing.
But it gives you more top end.

your loosing abit of spool, how much exactly i cant really judge coz my headers are leaking atm.

Id suggest what Terry-Wrist has said (Sorry forgot your name, its Alex isnt it? So many names from collie im confused!). Working the heads. What stops alot of people i would think would be the fact they just rammed their heads (100,000kms+) onto the 207 and went "awsome engine". Get the heads off, get some 03+sti heads and begin from there. Port, Polish, 272's with a bigger turbo and you'll find it easily walking passed 300 imo. Not to mention you awsomeness of shimless buckets and AVCS!

so what i should be aiming to buy is some uneaqual lenth headers, p20 rear housing, injectors (which ones)??

the autronic wont work with avcs....

[QUOTE=Josh;387021]the autronic wont work with avcs....[/QUOTE]

Sell it, get a motec. Like it was said, with power increases money will decrease. Even just getting Knightly over east to do your heads you are looking at 3k labour then some for parts. Awsome work, but costly.

Or. Leave power off to the avcs, change the cam wheels and use a non-avcs inlet cam. There are a few people doing it at the moment and a few that have done it. Only just got word of it myself.

When you can afford the motec + AVCS cam, sell the autronic and your stock cams then buy the motec and cam.

Are you intentionally ignoring the three people suggesting head work and cams?
By all means, do the headers, P20 and injectors, but you're heads are still going to restrict flow.

[QUOTE=Josh;387021]the autronic wont work with avcs....[/QUOTE]

lol yes it does.

do some more research before taking my word, i dont want u crying to me if u dont happen to reach ur goal :eek: :D :D

look on rexnet/nasioc etc plenty ppl have done this turbo conversion.

Dunno.. isnt sean ur tuner? talk to him.

[QUOTE=waxdass;387028]lol yes it does.
[/QUOTE]

Not a SMC?

ill be having words with sean soon i think ill slowley by the parts ao i can still drive the car then once i have everything ill get it fitted

[QUOTE=Josh;387029]Not a SMC?[/QUOTE]
hes got pnp... SM4?

PS: werent you considering selling? why fork out all this on a 9 year old car?

done the sums what will i buy with 20grand josh? i was considering it but its just not worth it... looking into buying a bunky and just thrash that everyday

dunno but keep driving this to my gym so i can have a look when i go in. ha!

what are you driving mate?

pnp smd doesn't do avcs nor does it do GD type intake manifold upgrades for the larger top feed injectors and all the other benefits without adding a stand alone boost controller to free up an aux driver.

if it was me, i would go a twin scoll conversion and reap the benefit of more torque and less lag, especially if you continue to use the fmic.

update heads, ts conversion, gd manifold + decaps & a boost controller it should be a very serious package in a gc8.

yeah - go twin scroll. i would of gone this way if i didnt blow my motor after i bought all the gear...lol

if his not bothered about loosing the air-con even go reverse manifold for that decrease of a few hundred rpm in lag or upgrade to a tmic.

Whilst its now the preferred choice for most bandwagoner's around here, and yes the TS option goes without saying. The lad wants more POWA!!!!!! nothing nothing nothing KAPOW!!!!!!!!!!!!!!! ZOOOOOOOOOOMMMMMMMMMM FARKIN BANG AND SHIT.

For the outlay, put some injectors in and tune it harder.


or put in an LS2.

[quote=jme;387058]

+1!

+2 and you would be the first to do it :D

Yep, get a V8 for power. Why bother with 4 cylinders if you are chasing big numbers?

[quote=wrxrw;386963]pnp or wire in smc?[/quote]

pnp sm4

smd doesn't do aftermarket injectors very nicely, sm4 seems a lot better at it.

fellas may i digress a little. can one have faith in a 205(rebuilt with forged pistons) @ sub 300hp at hubs?

also how does one make more torque?

EJ205's are strong little buggers, so have faith. Just not as strong as a EJ207...

Cams!!!!

CAMS CAMS CAMS!!!

AVO series turbos will net you over 300 easy with appropriate supporting mods (400 Series upwards)

:) Good Luck

Cams, Headers, TD06 final words only because you will get over 34/p20 very fast.

[QUOTE=xsv4rce;387186]with appropriate supporting mods[/QUOTE]

Most over used statement of 2009.

Dude, if your gonna go the full hog then best you buy yourself a new bigger turbo to go along withcams/headers/etc.

The vf34 is only designed to flow so much air through its 47.9mm comp wheel (same diameter as a vf35).
Adding the p20 exhaust housing just increases the rated flow to that of vf22 specs... ~480cfm @ 18psi.

a simple vf34-p20 is a cheap and simple turbo upgrade. It gives you increase in top end performance, without sacrificing too much bottom end.
If you want to keep your vf34 turbo - then may i suggest to upgrade the comp wheel to that of a PE1820 spec.

the PE1820 uses a dual BB catridge, and the turbo is essentially a vf34-p20 with a wheel upgrade...and a $2000 pricetag.

Product: PE1820F
Manufacturer: Power Enterprise
Turbine Specifications:
Housing A/R: P20Bore Size: 25.0mmTurbine Wheel Blades: 11
Turbine Wheel Inducer: 53.0mm
Turbine Wheel Exducer: 48.0mm
Compressor Specifications:
Compressor Wheel Blades: 6+6

This upgraded wheel transform the turbo to push out 630cfm @ 1 bar. (manufacturer rating).
I have heard that Adelaide Turbo Services (A.T.S) can upgrade your turbo for under $400.

So basically, if your gonna do it - then do it properly. It means that you wont have to boost your turbo high to acheive good power.

I didnt go this route coz its not what im aiming for. I'm keeping the stock 550cc injectors, and will push boost till they start running out. Whatever power/torque that makes then so be it. But the turbo defintaly has the potential to acheive some higher numbers if your prepared to push it.

With the added water/meth - think of it as essentially another injector squirting higher octane fuel. So with the combined injectors and meth spray - it will give me some more room to squeeze some more boost into the engine and dial some more timing into it, and see where it goes...

will turbo tech do something like this tode?

dont know mate, never looked into it much.

baisically i should be aiming for a pe1820 the difference between the pe20 is significant, some headers and cams, injectors and tune i think that will probably break the 300 mark

better speak to tristan & chris smith about the pe1820, im sure they will tell you to steer clear!

might make my way down to turbo tech this afternoon and go have a chat with the boys

Why not go for one of the other 10 billion proven 300hp combinations out there?

[QUOTE=WRXRW;387220]better speak to tristan & chris smith about the pe1820, im sure they will tell you to steer clear![/QUOTE]


how come? laggy?

or compressor prob too small for wheel...

Just to repeat whats been said 100 times already!

TD05 20G = GTPS02 = 300hp with supporting mods... = win?
