Default Second best after VF34 turbocharger for a Classic V2 Sti. Advice please !

Hi. As above, I'm looking for a turbo as an upgrade to my TD05 16g. I know that VF34 would be the best choice but was wondering if there is anything similar for a bit less money ?
My firs remap coming soon and with supporting mods I'll be looking at 350-360 bhp. I'm more about quick spool not top speed so...

I'm all ears :-)

For the money I doubt you will get anything better than a vf 34 to upgrade from what you have,you would need to spend more…

I'm not looking for a better turbo than vf34, I was wondering if there is anything better than TD05 16g but less pricey than vf34 if you know what I mean ?
Let's say £350 mark

You could try a VF35 but everything would have to work perfectly for you to hit 350bhp

Legacy,
What sort of money we are talking about for a new sc36 and where can I get it from ?

banny,
350-360bhp would be nice but it is not a MUST :-)
I'm just looking for a nice, not too laggy turbo with decent spool. As I said I'm more about torque than Bhp.

Have got a vf30 thats in between the vf35-vf34. Its spooling a bit later that them to but pulls hard till 8k rpm. I had upgraded from 16g as well and must say is much nicer car to drive now. Im porting the manifold and getting the upipe to get it spooled even earlier. Hope this helps.

Its a bit steap, even if the housing isnt cracked around the wastegate.... which it probably is or will be soon!

Doesnt effect low down boost much, but will mean it runs out of puff at the top.

I have a 35 and your right it boosts really well at 4k but also starts to spool nicely at 3k well thereabouts on mine. I suppose it is normal and does run out of puff at top end

Here's the latest :-)
I can have VF35 with 60k for £300
and VF35 with 28k for £350
Both units without waste gate cracks and posted.
Should I get one of these or wait for vf34 ?

VF34's are rare.. I got lucky finding mine.. Had a VF30 on before it and just couldn't get on with how late it spooled up.

Get the VF35 fit and map it and then if you don't like it keep your eyes peeled for a VF34 and remap it again.

Pretty sure one of the breakers would have Vf34 though.

Matty(Pole Pisition) has a mint but £450 is a bit too much for me to pay :-(
That 28k vf35 is also from him.

Buy it. Don't try and save yourself £100 on a turbo, especially when you are considering buying one you don't really want.

Just pay the extra - get the turbo you want - Job done.

If you buy a 35 and then decide you still want a 34 then you are spending out the £100 on the remap again anyway.

Hmm...
Didn't think about it :-(
I thought that these will be direct swap.

Both would be direct swaps but still need remap's mate.

Seriously heed my advise... I've learned this from experience!!

Your TD05 is a 90degree inlet or side entry, whereas the VF34 etc are front entry

People are either speaking from ignorance or to lazy to actually look at what car you have Don't waste your money IMHO. TD05 16g is a good turbo with the right set up and mapping

However...other options...talk to Andy F about his AFP5-16/18 turbos as this is based on the 93-96 90 degree inlet TD05. To the best of my knowledge these are like the Hybrid TD04's in that you see earlier spool and better boost efficiency. These are also offered on exchange for your old turbo for similar money to the VF you were offered by Matty albeit these are remanufactured by Andy to be better than new

Andy may also be able to assist you in converting a VF34 should you be able to source one in your budget.

What gearbox are you running, mods etc. It's better to run a smaller turbo and get the best out of it for the supporting mods than be a billy big bollox with a bigger turbo but fail to reap the benefits due to fragile drivetrain, insuffcicient injectors or maf limitations etc...

HTH

As above really. I dont think the vf34 or 35 would be enough of an upgrade from what you already have. You'd be better of exchanging yours for a 18 or 20g

Thanks a LOT guys for all replies. Much appreciated.
As for mods:

ON THE CAR ALREADY
- Major_Sarcasm CHIP
- fully decatted system
- K&N 57i IK
- Harvey ported headers with matching uppipe
- Exedy uprated Stage 1 clutch kit (done less than 2k )
- Lateral Performance lightened flywheel 6Kg
- Walbro 255
- NGK PFR7B spark plugs

WAITING TO BE FITTED
- freshly rebuild (by Three Arches) TY754 box with matching diff
- new ESL daughter board
- FMIC
- 550cc side feed injectors

Am I missing something on my list to achieve good torque figures ?

As advised above, my best bet will be to give a call Andy F and ask for advice regarding which turbo to choose if not to stay with my current one :-)

Thank You

I'm planning to keep the car and by little steps making it better and better. I rather chose a turbo I will like in aspects I've stated above instead of changing it after a month or so because of being disappointed.
I'm not in rush and if I will have to save a bit more money for a really good one, I'll do it.
