Which would you buy in my situation: Brand new VF34 from Scoobyclinic for around £650 + vat or a used VF35 (IHI) from ebay for £300 ish... http://cgi.ebay.co.uk/IHI-VF35-Turbo...QQcmdZViewItem

Looking to go on a MY03 WRX, running 264 BHP with full de-cat.

Neilo

VF35 personally, depends on the milage but for 300 quid it cant be that much...

you most likely wont be stretching it too much anyway and certainly wouldnt get maximum power out of either of them on a WRX. so save the £400 odd quid i reckon

[MikeyB]

Looking at getting uprated pink injectors, fuel pump and remap (including a new turbo) to hopefully get me between 320 and 340 BHP, does this sound realistic?

Why's that then..?

[MikeyB]

What should I be looking at then, TD05?

Neilo

Yeah thast realistic, the lower end of the scale is more likely, the more aggressive cams of an STI will get more out of these turbos as will the higher rev limit which is why i said what i said before. Just means that making the power is more likely and probably easier.

I believe the housing on the 35 is slightly smaller than the 34, so the 34 will give slightly higher peak power, but again, theres not much in it.

Neilo

no necessarily no, these turbos will do you just fine.

The 34 would be my choice, roller bearing low friction turbo rather than the sleeve bearing slightly smaller vf35.

Tony

Neilo

but can it justify spending over double the money on it?

I'd be tempted to find a good used Front Entry TD05 16G................simple, old fashioned but a tough critter with good spool up

VF35 will spool quicker with its P15 exhaust housing and max out around 340ish. VF34 is roller bearing as Tony mentioned but will spool slower (upto 500rpm later) due to its larger P18 exhaust housing. We have seen a VF34 make 370 HP on our Dyno Dynamics Dyno but it was running the wrong side of 1.9 bar to get this. Personally I'd go with the VF34, its new, its GVFM, warranty and if you get the internals done at a later date you can push it that bit harder. The cams wont be a restrication in your WRX as the inlet cam is more agressive than the STi and we have found the WRX to respond very well to the upgrade of STi pinks, STi or aftermarket top mount intercooler and Turbo (VF35 or VF34) Dont forget the fuel pump upgrade

If your goal is 320-340 then go for the VF35 @ £300. Why waste money for a slower spooling turbo when you aren't going to push it that far? You'll get your money back when you want to upgrade the power further at a later date but you'll only lose money on the VF34.

my mapper said he would alway choose the vf34 as it has less surge issues -

Brun

Nowt a bit of porting can't fix

RLE

Shameless plug Mikey but I'll have a VF35 coming off my 53 plate sti8 at the end of the month as I'm upgrading a few bits and going for a bit more power.

Low mileage (documented 18k from new) Sent you a PM anyway just in case you are intersted.

Rob

Bob Rawle

VF34 for preference, wouldn't buy a turbo off ebay so RLE's option looks good BUT port the wastegate as it will creep.

BTW trying to run 1.9 bar on a turbo this puny is asking for trouble, I have made 360 (just under) from a VF35 runnning 1.45 bar mid and 1.3 bar top with supporting mods (on Optimax and booster blend) in a customer car. Ringing its neck though. Not having a go but just sanity statement.

if you swap a P18 turbine hsg to a VF35 you have ...??

RLE,

Can I express an interest in the VF35, obviously second to Mikey B if he wants it

RLE

iTrader: (2)

Sure mate.

Should be off next weekend with a bit of luck (24th)

Floyd

iTrader: (9)

Agree with Bob that ebay may not be the best place for turbo's!

My VFM statement still stands unless you could source a VF34 for similar money.

F

[MikeyB]

Go for it mate, I'm not planning on upgrading just yet.

paul walker

i have three vf34 turbos of my rally car one is good the other two were starting to pass a little oil.

anyone who wants them can collect them from me in north yorks. or call 07808914448.
will be doing dukeries rally this weekend (mansfield) so could bring them.

The Fixer

Just to clarify the VF34 running 1.9+ bar wasnt one of our cars, it was in for a turbo change to an APS SR40 and was found to be running this on the pre-modification power run. After chatting with the customer he knew about it and was quite happy running this on standard internals as well

Good to note though that it needed alot less boost on the new SR40 to produce more torque and power after the remap so maybe it will now live a lot longer

For £400 why not gte a TD04-Hybrid from Andy F ?


http://www.andyforrestperformance.co.uk/16307.html

You'll retain the rapid spool but get VF35 ( -ish) power ?

Just a thought as i have this predicament but want ultra quick spool

See my post above......... I wondered if the Mitsubishi TD series was out of favour for some reason ?

But won't a td04 hyprid struggle to get over 300BHP? Has anyone ever fitted one, and can they be used with a tek 2 map?

Midlife......

iTrader: (2)

I thought off the shelf (example / TeK 2 ) EcuTeK maps had died a death......

on a Bugeye WRX I'd have thought that a Hybrid TD04 with supporting mods (filter / exhaust / STi TMIC / pink injectors etc ) would have hit 330 BHP easy

Shaun

~~ Cal ~~

See Andy F's articles in Scooby mag for the power he was making..........

The latest developments on our 03WRX will be posted here.

4th Feb 05

Version 1 of our Hybrid TD04 turbo (mild port and polish) is tested at Dastek rolling road and makes 300bhp and 322 lbft of torque

3rd March 05

Version 2 of the Hybrid TD04 turbo (new compressor) is tested at Engine Advantages rolling road and makes 329.5 bhp and 314 lbft of torque. Up on power but down on torque from Version 1

12 March 05

Version 3 of the Hybrid TD04 turbo (another new compressor) is tested at Dastek rolling road and makes 312.3 bhp and 338.6 lbft of torque. Well up on torque (and it feels it !) but power dropping earlier at the top end.

24 March 05

Final version of the TD04 hybrid with a modified exhaust has been tested for the past week but the tubular headers expansion piece has blown :-( delaying a rolling road run. Road-dyno figures were very promising, combining the power and torque of version 2 and 3.



6th April 05

Megan tubular headers are fitted with version 3 TD04, these share the same expansion piece as the previous headers, attempts are underway to 'blow them up' using the normal levels of abuse that the subaru can be subjected to !

Initial impressions are not good, lack of torque off boost and a 200 rpm later boost threshhold. On boost, similar peak torque and power to previous small bore units has been achieved.

20th April 05

Well they didn't blow up but the trade off in response was too much. I have now fitted a set of fully ported OE headers and regained the off boost response. Torque is unchanged and peak power is only down 5bhp on the best tubular header result.

October 05

The car is now fitted with AFP 5-16. Although peak power is up by around 30bhp, overall throughout the full 2000-7000rpm range the car is no faster however if the rpm is kept above 4000 then the difference is much more noticeable.

Febuary 06

AFP 5-18 turbo was fitted and after a few wastegate and map adjustments, power climbed to 378bhp and torque was 365lbft (still on sti8 tmic) Full boost from 3200rpm right to the 7000 rev limit. This is how they should have come from the factory !

Red 16G 350bhp Blue 18G 378bhp

Cal,

Thanks for the info, Andy was originally top of the list for the replacement turbo - and if I went that route it would probably be for the TD05-18G

I have particular 'issues' based where I am, where the shipping cost is likely to be around GBP50 each way. The TD04-AFP4H is GBP400 + Vat (which I wouldn't have to pay) on an exchange basis, so including dual shipping would be GBP500 total.

The VF35 would be around GBP350 total, making the TD04 GBP150 more expensive, an increase of 40%!

I would also not be convinced that the ECUTek tuner I can use here could extract the same results as Andy F from the turbo - and flying him out would not be financially viable!

I already have (what appears to be!) a very 'laggy' setup with the entirely mismatched TD04, 3" decat exhaust, Helix up-pipe, APS CAI and APS FMIC all badly managed by a Unichip piggy back controller, so a 'slightly' more laggy VF35 and ECUtek would probably improve over the **** I have already!

I want to do 'something' and if I keep waiting for the perfect solution I will never do anything!

Neil
