Yep. He really is a waste of skin.

LOL. Sort of true sadly.

lol I have no idea........3 pages in and I'm still in the dark :)

Several choices of turbo to fit the bill - depends on who the chosen tuner is and what he wants from the turbo, oh and of course how much he wants to spend.

To be honest, if you're happy to not chase numbers I'd be inclined to save a bit of cash and get a VF turbo with a billet wheel instead over anything posh like a SC turbo. I have a friend who has a VF43 with billet conversion and it's making a solid 375 bhp and 420lb/ft and drives very well. Very spooly combo without going too large on the turbo.

Hi Domino,Can I ask where you had the Billet conversion done on your vf48 please?

Few places do them but there is a guy on Facebook who rebuilds Subaru turbos and does billet upgrades for sensible money. His name is Craig Bellworthy. have a search for him and send him a PM, he's a motorsport technician at Maclaren.

my vf43 is already billet according to my paperwork,it was sent to cr turbo's in 2014 for billet wheel and new actuator.

at the minute its 350bhp with around 370ftlbs which i find low, my old 2.0 wrx with a vf35 mad 365ftlbs and that was a 2.0.
would the vf48 be a better choice?
does having aftermarket or ported headers/up-pipe help with torque?

my car isnt slow by any means and it spools its nuts off i just feel its lacking mid-range a little. my last impreza had 440/440 so perhaps thats why i want more

Yes that will all help build boost. Ported headers or GT spec headers and Harvey trick up pipe will also help. Also a FMIC may gain you 10-15bhp additional over a TMIC but may change the way the car drives slightly as a result. Not getting into the age old TMIC vs FMIC argument yet again. lol

Sounds like your car is making good numbers for the turbo currently fitted and supporting mods then to be honest.

i have since changed to a full 3" exhaust afterburner system as it was a 2.5". i already have a fmic.
headers are std and up-pipe is of unknown origin so will get a set of rcm headers and a trick up-pipe and maybe have the boost turned up a little.

To be honest that sounds like a good idea to me anyhow. You will want all those bits if you do decide to go to a bigger turbo, so worth seeing what your current turbo will push out first.

will get searching for a set as im not paying £600 odd for a set.

might get a fuel pressure reg aswell.

Or find someone to port your standard headers. I've been told that ported standard headers are also very good.

will speak with alyn @ as performance for a price aswell as a wrapped up-pipe.

Below 400 i thought gt-spec took more away down low than they freed up top,

Was told the tubular Gt-sec style wouldn't help spool either until pushing big numbers when sock become a restriction,

Over 400 tho its up across the board,

(Approx. obv it wont be bad on a 399bhp car but great on a 401bhp car)

Thanks,will be sure to look him up.

Sheksta... Sounds like a have the sort of turbo you want. (its not for sale so don't get too excited)

I have an AFP GT-420 on my 2.5 wagon.
It made 380bhp and 375ftlbs @ 1.3 bar on the dyno. Torque comes up very quick.
Will easy see 400 with some more boost.
Engine is forged with STI up-pipe, STI TMIC + the usual exhaust and fuel upgrades.
Turbo fits in stock location.

I'm not sure you can buy these turbos from Andy Forrest anymore but FYI its basically a TD05 20g with Garrett GT30 core and billet wheel.
Hope it helps.

hi and thanks for the reply, I have decided that the engine will now get a rebuild to allow me to run the power I require so now looking at 500bhp capable turbos.

Thanks anyway buddy

cough cough FP red lol

I looked on their website, dont you have to run their 84mm intake hose?

and what power you running again or you still fixing it lol ,, advice from someone who hasn't got a gt30 or a FP red lol at least my advice is first hand

I am but have seen other running other intakes so assume others fit aswell ,, saying that there intake is a awesome bit of kit

Lol raggy. There are a few dynos that will get you 500 if you want ? 😀. As raggy says gt30 billet rotated will easy get you 500. I'm running this on my 2.5 .

thought it just needed a syvecs fitting and mapping ? ,,, if thats the case then why is it taking so long to fix as its a days work at most ?? ,, someone is chatting doo doo and sounds like still trying to fix it lol

at least my car works and I'm out having fun in it ,, unlike you cry wanking on your driveway

yes but mine isn't rotated and there is massive price difference between them
