I've been searching for old threads but can't find anything, i'm looking to upgrade my UK turbo, as i only use it as a summer car so want it to be more impressive for the short time i drive it


At moment i have, Japspeed manifold, Ninja sports cat, Powerflow 3" cat back, Subaru pro R filter

I'm guessing i need, new fuel pump, Injectors, Esl ecu, hoping with those mods and a remap, i'm hoping i would be able to get to 280bhp

Question is which fuel pump? Injectors? And would i need a upgraded turbo?

Thanks

If you are only after 280bhp and your injectors are yellow they will max out about 340-360 bhp where there running 100% dc Yellows Im pretty sure there 440cc.Fuel pump should be ok as it is,Clutch should also be ok with the power.Im told the td04 runs out of puff at 290bhp and very few have seen 300bhp with supported mods.I don't no if you have the td04 or td05 on yours.I think the upgrade after that is a VF turbo or even a td06

what year is ur car? u can get 280bhp on a td04 with a remap, esl is available on 97-98 and ecutek on later. 97-98 have 380cc injectors, grey and 99 - 00 have 440s, yellows.

Its a 1998 uk turbo, i think i have the td04

So why do the 99-00 have the 440 injectors if same bhp?

For some reason the later versions did have yellows .
The standard td04 turbo runs out and I got 264 bhp from

Standard everything . Part fromair filter and fuel pump

Wanted more so I put 3" exhaust with sports cat
Yellow injectors
Vf28 turbo

And got 310 bhp

Think someone on here claimed they got 300bhp off sightly modified low mile engine

Which phase 440 injectors would i need

jaygsi

iTrader: (46)

phase 1 or 2?

I would say a 2000 model because I have a 2000 forester with yellows.Ive seen a lot with td04s getting 280-290 with supported mods and map

You need phase 1 or phase 1.5 fuel injectors. You can use phase 2 injectors but you'll need an adaptor kit, Carl Davey sells them.

jaygsi

iTrader: (46)

Which is best or both same?

Do I even need bigger injectors, as I'm only after 280bhp? Thanks

MattyB1983

iTrader: (51)

Any pre99 (phase 1 / 1.5) 440 will be fine. I would definitely suggest a set if heading towards 300bhp.

jaygsi

iTrader: (46)

So for 280bhp you think i just need 440 injectors and an esl remap?

MattyB1983

iTrader: (51)

If it was me.......

440's
255 fuel pump
Full de-cat exhaust
Decent panel filter
Pfr7b plugs
ESL map.

That'll see somewhere around the 280 mark and make a nice road car.

Ok cheers Matty, i'm sticking to 100 cell sports cat, but yes wanting a nice road car, my WRX was a beast but sold it years back as wasn't a spec looks wise as my Uk turbo

Got new panel filter
Going to buy NGK Pfr7b

So just phase 1 440's and 255 fuel pump, then ESL, remap and away

Not anymore. Carl's knocked it on the head, and Alyn has the rights to all his stuuf, IIRC.

Oh really, didn't know that buddy. Cheers.

any more suggestions i'm willing to listen?

Suggestions for what mate ??

Of modifications, or if thats the route i should go

You already have 440s, your injectors will be yellow, only pre-96 were 380s.

If your intercooler is standard it will limit output. A FMIC will give in the order of a 10% power increase.

A cheap upgrade would be a td05-16g or in tank meth.

jaygsi

Hi Andy will the td05 be a direct fit?

And my injectors are grey bud

MattyB1983

iTrader: (51)

Grey injectors are 380's.
TD05 will bolt straight on but you'll need to find one (or do it yourself) that has been converted to front entry. 16G is a good turbo and with the right supporting mods will see circa 320bhp pretty easily.
Front mount is a good shout but for what your aiming for I'd look at a newage WRX top mount. Larger than your current cooler and can be picked up for peanuts these days.

MattyB1983

I'm fairly sure the UK cars didn't get 440's until 99 Andy.

jaygsi

iTrader: (46)

Yes i was thinking top mounted intercooler upgrade aswell, will have to see if i can get one cheap, as alot i've seen have gone for £150

My mates old MY97 UK Turbo had 440's as standard, IIRC.

However, 97/98 was a bit of an odd time with things crossing over.

MattyB1983

iTrader: (51)

Newage STI ones make circa £150, you'll pick up a WRX one for a third of that.

MattyB1983

iTrader: (51)

The terzo came with 380's and that was a 97 car for instance.
Like you say, odd times no doubt.

Sometimes I think Subaru just fitted stuff that was closest to hand half the time....

mickywrx

iTrader: (29)

There could be a whole lot of truth in that.

Some were definitely "Friday afternoon" cars.

jaygsi

iTrader: (46)

WRX ones arn't as good though?

MattyB1983

iTrader: (51)

I'm aware of that chap, hence why a WRX is £50 and an STI one is £150.
Depends what your budget is doesn't it. But your not after big power and a newage WRX one will be a nice upgrade for you and easily cope with what you want it to.
