Time for "the" upgrade!

23 March 2008, 16:59

Hey,

Gonna be performing an upgrade to my MY05 WRX SW relatively soon and was hoping for some constructive "criticism"/advice on the following equipment upgrades.

Starting from back to front:

--Perrin Stealth Cat-Back Exhaust with the associated up and down pipes.

--Perrin Top Mount Intercooler

--Perrin WRX Fuel System (maybe still considering)

--New hosing

--IHI VF 34 Turbo

--Iridium Spark plugs

--Upgraded clutch

--Quickshift

--Dash mounted instruments for oil temp and so on.

--Intercooler water spray and associated water tank

--Tarox 10/12 pot brake upgrade (front and rear) or Brembo......

--(Already got STi strut bars)

--Remap of course!

Dunno if I am missing anything else?

Hoping to extract around + 320 BHP

Perrin WRX Fuel System, considering it, even though it is a bit expensive.

Also forgot the K&N filter.

Still wondering about the top mounted intercooler though.

Thanks for info!

i would add a bigger turbo inlet , consider the Perrin 5 or 6ply silicone inlet , allows faster spool.Are u using larger injectors , consider STI pinks 565cc.

So the original STi injectors that good?

Looking for around 320 PS, not really monster power (yet) and to be able to ride around town, go to work, to the shops and so on.

I think I can picture that, could you elaborate a bit?

The VF34 seems to be the most able kind of Turbo in the VF range......

i am no expert , just writing from experience , had the perrin turbo inlet with VF30 similar to VF34, no surge with stock size 65mm intake pipe with the perrin turbo inlet tapering to 2.4''.
The sti pinks are good , but i max mine at 95% duty cycle with my VF30 .My experience > 350bhp , go larger 650cc. But u are aiming for 320bhp , they will be ideal .

Recommend also wrap downpipe and use turbo wrap or get jetcoating on the VF34 , because those IHI turbos as compared to MHI turbos give off far more heat . The sti TMIC will work , but will get a lot of heat soak , once u are on the fly TMIC will be very cold , but at the lights it heat soaks like hell. With the wrap and jetcoat your IC water reservoir will last longer . Makes a huge difference .
