As title really , not sure whats best to get , or value for money along with reliabilty etc , looking to achieve mid 300's if poss ,

I already have a full de-cat , typhoon induction kit and re-map (liscence paid) and will be looking at injectors and fuel pump alongside turbo



Any advice will be great as i really dont know the best way to go

 

I have a VF34 which is very similar to the VF35. I understand the 35 spools slightly earlier but has less at the top end. I don't know anything about the TD05 but am well pleased with my VF34 which was supplied by powerstation a couple of years ago.
It takes quite a lot to get a WRX up to 350bhp with good torque, I think I was around 330/311 with similar mods to the one's you are planning but cars do vary.
Hope this helps
cheers

If you want a TD05 16G then, because it's top entry, you'll have to get the compressor cover converted by having an engineering shop cut the snorkel off and re-weld a suitable length collar back on for your 'under the IM' turbo intake hose.

But forget that, just fit a straight swap VF34 or 35. AFAIK they have very similar spool characteristics as the TD, and similar power capabilities i.e. upto 350bhp. One of those VFs (can't remember which) is a roller bearing version of the other, which means it spools slightly quicker, but is that bit more fragile (I think).

 

VF34 is rollerbearing

Sparky,
I may be selling my VF34 and STI 550's, I haven't come to a decision about another upgrade yet but I'd be looking for about £400, turbo and injectors
cheers

I had a VF28 on my classic and now a VF30 on my 02 WRX. Bought the 30 for £150. Its boosting at 1.5bar
Bang for buck, you wont beat it.

 

Oh sorry, does that mean the 34 has more top end... and 35 spools quicker, then?

 

Yes I think that's it

 

Nice one trevsjwood , are you coming to the meet on the 22nd ? if so i could have a propper chat with you then and take it form there

Ok buddy see you then although the wife will be there and we'll have to use coded speak - like every thing half it value

 

i know what you mean mate , its ideal for me as she cant make it , i'll keep it low key

 

I have the VF34.
I had the VF35.

As it was already mentioned here, the 35 does spooles a little faster, but get to it's top end faster too...
it chunk's where the 34 keeps on boosting and beating. there is slight difference in the kicking of the turbo. the 34 gets in more linery way then the 35, and last's much longer then him. it last's up to the max rev's without any power losses of the engine.
Defently recommend the 34 on the 35.

 

I have the vf34 also, but often wonder what it would be like using the hybrid td04? These are good for over 300 and maybe 320 i think. That way you keep the best of both worlds

 

I think the AFTD04 Hybrid is only good for 290bhp (I'm sure that's what it states on AF's site ). So if you're happy at the sort of level, then great!... A really low spooling turbo with max boost developed at about 2,500rpm, held all the way to the redline like the TD05 ...... However, you have to ask yourself: "Will I want - nay, need - more?!"

The choice, as they say, is yours...

 

Exactly mate , as you say the best of both worlds but knowing what i'm like i'll be wanting more soon enough , i'll start the hunt for a vf34 then , i can get a new one of these for aroung 550 so hopefully find a good used one for 300 maybe ???
