looking for an upgrade currently running circ 340 and wanting to get closer to 400 (turbo, engine are standard)
i have a my02 sti , what do i need to obtain these figures
is it just the case of bolting on another turbo?

if so what would people say would be a good upgrade

cheers phil

Fuel pump, injectors, turbo, remap etc.....

fuel pump has already been changed to walbro 255 is this not good enough ??

also arnt the injectors in a sti good for 400 ??

which turbo do people generally go for ??

I had to up the fuel pressure to 4 bar on OEM injectors to get near 400 bhp...

Fuel pump is sufficient.

A hybrid TD will get you to around 380, an MD321H will make 390-410, a T will make more...

Full Decat turbo back 3” bore exhaust system sportscat will be fine
ported and wrapped headers and uppipe
Walbro 255 l/hr uprated fuel pump
K+N panel filter
Ecutek custom remap
Twin boost set up for high/low power switchable in-car
NGK PFR 7B uprated spark plugs
Fuel Lab turbo specification fuel pressure regulator with fitting kit & gauge set at 4bar
td 05-20G custom turbo charger

i done all this to my last car for 1700 quid

sc46 billet will prob get you there oe there abouts.

i see cdf are selling a 20g would this be suitable ?

assuming its the one off there demo car. will prob be a bit laggy and not sure if it will make the 400. TD05's are pretty long in the tooth tech wise now

I was hoping for 380-400 with this turbo, I know 400 maybe asking a bit much but I did read on here the other day someone made 410+with the 20g

more info

anyone?

Anymore info that can be shared on this post ?

JayAllen made just over 400bhp on his Bug STI using a 20g and remap.

Can't remember what else he did, but don't think it was a lot.

400 on 2.0 can be laggy.

SC38 turbo probably the best compromise.

So what sort of price is the sc38 and do you need any more supporting mods ?

Turbo and stuff has moved on when i used the td05 20g it was under 400 bhp but now you get the billet version with supported mods and easy be on target for 400 with even quicker spool.

I made 416bhp 370ft/lb on a aet td05-20g sold by ra motorsport in perth
