[QUOTE=coolgavin97]Hi guys,
Could anyone tell me what is the standard boost PSI for My98 WRX? And what is the safe boost if I want to boost up. The only mod I have is the intake and exhaust.
Thanks![/QUOTE]

I had a MY98 with exactly the same mods as you and my boost gauge read 14.5psi

i think the standard for a my98 is 13.5 psi

[QUOTE=mr_psi]i think the standard for a my98 is 13.5 psi[/QUOTE]

And [I]you[/I] would know.... Mr psi....

its just under 1 bar 14.3 psi or something very close

Hi Prodigy, did your WRX running the standard boost at 14.5psi? or did you boost up already? If 14.5psi is the standard, its pretty high, isn't it?

Mine was stock standard except the exhaust and CAI. 14.5 psi should be pretty much the norm for a standard MY98..

hey thats a pretty cool list, where'd you get that from?

a tad innacurate as some 01/02 STIs got the VF30 too. But defintely worth a sticky

moved to mechanical section and stuckied.

i had it in "My Documents" i dont know where i got it from. I know its not 100 percent accurate but gives you a good idea what to expect.

Hope it helps

awsome list hey helpfull as

mine is 98 wrx with vf30 and mine runs 16 standard

You're car came with a TD04 standard :)

When my 98 was stock it boosted at 13psi and sometimes 14psi.

i got a 2000 GC8 wrx same as the 98 a standard wrx like that comes out at 12 psi a safe boost is about 14 or 15 if you wana really give it som peak tweak dont no if that will blow a seal or bearing shouldnt do mines been fine for about a couple of months now

Turbotim????


Generally it helps if other people can read & understand what you post. A full stop or a comma would make it legible, it's not that hard.

A 2000 gc8 and a 98 gc8 are completely different animals. They run different turbos and the 2000 has a different engine / manifold design.

2000 runs 14.5 psi stock and a 98 13.5 psi stock.

1 bar is pretty normal.. its not 1990 where 8psi was the norm.. engine was built with turbocharger in mind

stock standard gc8 wrx runs 2 p.s.i if your looking to boost hard but not blow nething you wana boost round 14-15 thats wot i ran mine at, she had a bit of poke but nothing broke :P but my advice get sum coin togetha nd jst mod the lot nd tune only way to go.

I'm hoping he means 12psi like his post on the previous page.

Then that just means cheap china gauge is reading slightly under (as expected).

Although 2psi would explain how the evo dishes chop :D

Which model of STI running VF34??? ANyone knows?

2002 type-ra (spec-c)

How about the 05-06? I was told its also using VF34?

MY03 - MY05 STi (PEANUT), Turbo: VF35, Boost: 16.4psi.

MY06 - MY07 STi (PIG NOSE), Turbo: VF43, Boost: 14.93psi.

You have been told incorrectly.

My bad gavin, I read it in dyslectic:o

haha no offensive Paul, I was just wondering what year should the VF34 come off from, since I can't find it myself so ask around... but I know VF34 is the best in respond.. and hoping to get 300hp on wheel.

Sorry to ask a silly question but what does a 97-98 spec boost to if the factory boost soleniod is deleted??

7psi.

13-14 psi sounds about right, expecti it to creep up and drop back down when its cold out side

My old 98 used to run 14psi STD. But they used to have problems with boost control solenoid mounted on the rh guard. This resulted in a drop to 7psi. Can remove them and spray out with carby cleaner.

And?
